A perfume adds a scent to a cabin. It does not remove one. So when a car has started smelling of something it did not smell of before, the first question is about the car

Yes - and the reason is more interesting than the answer. The word longevity is doing two jobs in your question and they come apart cleanly. One of them is published and auditable: how long the bottle lasts, which SOSA states as a count you can check yourself. The other is not published at all: how long a cabin stays noticeably fragranced, for which there is no figure anywhere in the range - not for you, not for somebody who keeps the windows up all journey, not for anybody. So the honest answer is that you should judge it differently, but against a baseline you record rather than a standard somebody published. There is no published standard here for a bottle to fail.
Two longevities, and only one is published. Bottle life is countable and the figures hold however you drive: a 10ml spray is ₹449 to ₹549 and holds 100 sprays, a 50ml is 500, and a 12ml hanging at the same price runs 4 to 6 weeks of continuous diffusion with the stopper as the strength control. How long a cabin stays noticeably fragranced is published nowhere - no coverage, scent-throw or projection figure exists - so there is no published persistence standard a bottle could be failing, and the baseline you judge against is one you record over three like journeys.
Quick answers — read this first
Should an open-window driver judge car fragrance longevity differently? Yes, but notice which longevity. Bottle life is published and countable - a 10ml spray is 100 sprays, a 12ml hanging runs 4 to 6 weeks of continuous diffusion - and those figures hold however you drive, because they are counts of what you bought. How long a cabin stays noticeably fragranced is not published for anybody, so there is no shared standard to judge against. Your baseline is the one you record over a few journeys.
Is there a published figure for how long car perfume lasts in the cabin? No. SOSA publishes counts of supply and no persistence figure at all - no coverage, no scent-throw, no projection. So when somebody says a car perfume lasts a certain number of hours in the cabin, that figure is not coming from any published SOSA source. What is published is 100 sprays in a 10ml, 500 in a 50ml, 200 in a spray combo, and 4 to 6 weeks for a 12ml hanging, plus the stopper as the strength control.
What should I measure instead? Three things you can actually record. How many presses a week you are using, which tells you whether the bottle is meeting its published count. Where the stopper sits on a hanging, since that is the published strength control. And what somebody else says when they get in, because you may stop noticing your own fragrance part-way through a drive while they notice it clearly. That is a baseline rather than a figure, and it is the only honest one available.
The short answer
Short answer: Yes, but against a baseline you record rather than a published standard, because no published standard exists. SOSA publishes counts of supply only - 100 sprays in a 10ml, 500 in a 50ml, 4 to 6 weeks for a 12ml hanging - and no coverage, scent-throw or persistence figure at all, for any kind of driving. A 10ml spray is Rs 449 to Rs 549. So audit the bottle against its count, record your own three journeys, and ask whoever gets in later. And if the cabin itself has changed, fragrance adds a scent and does not remove one.
The pick: A 10ml SOSA car perfume spray, ₹449 to ₹549 - because the one published figure you can genuinely audit is the count of presses, and a spray is the format where you control every one of them.
Why: Judging against a count you can check beats judging against a figure nobody published. A 12ml hanging at the same price publishes its own auditable figure instead - 4 to 6 weeks a bottle - with the stopper as the strength control.
Two different questions get asked in the same words. One is "which fragrance suits my car", and that is a preference, answered by the format: a 10ml spray is published at 100 sprays, three months at one a day and fifty days at two, while a 12ml hanging at the same price runs 4 to 6 weeks with a stopper that loosens for more or tightens for less. The other is "my car smells wrong and I want it to stop", and no perfume answers that one, because a fragrance adds a scent and does not remove one. The second question is about the car - and it is worth knowing which of the two you are actually asking before you buy anything.
If I enjoy open-window driving, should I judge car fragrance longevity differently from somebody who keeps their sedan shut and air-conditioned for the whole journey?
Yes - and the useful part is working out what you are allowed to judge against. Your question contains two different ideas of longevity, and separating them settles most of it. The first is how long the bottle lasts, and that is published.A SOSA 10ml spray is published at 100 sprays - three months and above at one spray a day, fifty days at two - the 50ml at ₹1,499 is 500 sprays and about a year and more, a spray combo is 200 sprays, and a 12ml hanging runs 4 to 6 weeks, that is 28 to 42 days, of continuous diffusion in refillable glass. Those are counts of supply, and you can audit every one of them yourself by counting presses or weeks. They do not change with how you drive, because they describe what is in the bottle. The second idea of longevity is how long the cabin stays noticeably fragranced - and SOSA publishes no figure for that at all. No coverage figure, no scent-throw figure, no projection figure, nothing. Not for open-window driving, not for a journey with the windows up throughout, not for anybody. So the sentence worth keeping is this one: there is no published persistence standard your bottle could be failing. If somebody has told you a car perfume should stay noticeable for a particular stretch of time, that number did not come from a published SOSA source, and holding your bottle to it is holding it to a figure that does not exist. The one published line that touches conditions says exact longevity depends on cabin temperature, stopper setting and how often the car is driven - and its subject is bottle life. So what should you judge against? Something you record. Run the same scent at the same single press for three journeys that resemble each other, note where the stopper sits if you are on a hanging, and ask whoever gets in next what they notice - because you may stop noticing your own fragrance part-way through a drive while somebody joining later notices it clearly. That is a baseline, and it is yours. Judged that way, the open-window driver and the windows-up driver are not competing against one published figure; each is checking a bottle against its own published count and their own recorded experience. Prices, so the choice is not clouded: ₹449 for Jasmine, ₹479 for Lavender and Sandalwood, ₹489 for Icy Mint, ₹499 for Lemon, ₹509 for Oud, Vetiver and Sea Breeze, and ₹549 for Mysore Orange Blossom, which is spray only. Spray and hanging cost the same, scent for scent. And one check before any judging at all: if the cabin has started smelling of something you could name, no standard will help, because fragrance adds a scent to a cabin and does not remove one. Find it, dry it, air the car out, and set your baseline afterwards. A portion of every SOSA order supports girl-child education through Nanhi Kali.
Bottle life is published and countable. Cabin persistence is published nowhere, for anybody.
The quick version: bottle life is published, cabin persistence is not.A 10ml spray is ₹449 to ₹549 and holds 100 sprays; a 12ml hanging is the same price and runs 4 to 6 weeks. Audit those, and record the rest yourself.
Two meanings of longevity, and only one of them is published
This question is really about what standard applies, so it is worth setting out what a standard would need. It would need a published figure - something you could be measured against and found short of. Three things follow from whether one exists.
01
Two kinds of longevity
Bottle life is published. Cabin persistence is not
Say the two out loud and the question becomes answerable. How long does the bottle last? Published, countable, and the same figure whatever your windows are doing: 100 sprays in a 10ml, 500 in a 50ml, 200 across a spray combo, 4 to 6 weeks for a 12ml hanging of continuous diffusion. Press-count and weeks are things you can verify. How long does the cabin stay noticeably fragranced? Not published. Nowhere in the range is there a coverage, scent-throw, projection or persistence figure, for any style of driving. So an open-window driver and a windows-up driver are both auditing the first and improvising the second, and the only difference between them is what their own improvised baseline turns out to be. That is not a weakness in the answer. It is the answer, and it stops you measuring a bottle against a number nobody published.
Tip: Count the presses. There is nothing published to count the hours against.
02
The sentence that is published
One line about conditions, and it is about the bottle
SOSA publishes exactly one sentence connecting conditions to longevity, and it is worth quoting precisely rather than paraphrasing generously: exact longevity depends on cabin temperature, stopper setting and how often the car is driven. Read the scope. It is a statement about how long a bottle lasts - a hanging in particular - and it names three things, none of which is a window. It says nothing about scent-throw, nothing about how strong anything smells, and nothing about how long a cabin holds a fragrance. Stretching it into those would be the easiest mistake on this page, and plenty of writing about car fragrance makes it. What the line does legitimately give you is permission to expect bottle life to vary with real conditions, and a reason to record your own rather than expecting a single figure to describe every car. The stopper being named in it is also the practical hint: on a hanging, the strength control is published, and the advice is to start tighter and open gradually.
03
The baseline you can build
Three journeys, one rate, and somebody else's nose
Here is the method, since no published standard exists to replace it. Pick one scent and one rate - a single press - and hold both steady for three journeys that resemble each other. Not one open-window drive against one long motorway run; three of the same kind, so the thing you are varying is nothing. Note what you notice at the end of each, not at the start. Then add the part most people skip: ask whoever gets in next. You may stop noticing your own fragrance part-way through a drive while somebody joining later notices it clearly, and that is the plainest reason to check before adding more rather than topping up at every junction. SOSA publishes no rate or timescale for that and none is offered here; it is simply what people report. After three journeys you have a baseline - your own, recorded, specific to how you actually drive - and from then on a change means something. A figure borrowed from somebody with different windows never did.
Tip: The most reliable verdict in the car is usually not the driver's.
The one number that settles most of this
A 10ml spray is 100 sprays. The rest is division.
SOSA publishes the count on the bottle: a 10ml spray is 100 sprays, and the 50ml is 500 sprays and about a year and more. The pages state the working too - three months and above at one spray a day, and fifty days at two a day. That turns a vague question into an arithmetic one. Spray before every journey and somebody making four short trips a day is out of a 10ml in about twenty-five days; the same bottle in the hands of somebody who sprays once each morning lasts the published three months. Neither is wrong - but only one of them is what the person expected when they bought it. So work out your own number before you decide the product is not lasting. And note what the count does not tell you: SOSA publishes how many sprays are in the bottle, not how far one spray reaches or how strong it will seem, because no coverage or scent-throw figure is published at all.
Build a baseline in three journeys instead of borrowing one
Pick one scent and one press, and change nothing else for three drives.
Choose three journeys that resemble each other, not three different ones.
Note what you notice at the end of each drive rather than at the start.
Ask whoever gets in next, then audit the bottle against its own count.
The SOSA principle
People judge car fragrance against a persistence figure they have never seen published, and then conclude the bottle underperformed. The figure is what is missing, not the bottle.
What is published is a count you can audit in a week. Hold the bottle to that, and hold the rest to a baseline you wrote down yourself.
The nine scents, priced, and the one figure each format publishes
Because every scent is the same price in either format, the baseline you build does not have to be rebuilt if you change scent - which makes experimenting cheap in effort rather than only in money. Oud at ₹509, Vetiver at ₹509 and Sandalwood at ₹479 are the deep end of the range. Lavender and Sandalwood at ₹479 sits between soft and woody, and Jasmine at ₹449 is the floral. The bright three are Icy Mint at ₹489, Lemon at ₹499 and Sea Breeze at ₹509. Mysore Orange Blossom at ₹549 is spray only, with no hanging version, so a baseline built on its stopper setting is not available to you.
The side-by-side
Four standards you could hold the bottle to, and which ones exist
The option
Who it suits, and where it fails
The published count - presses, or weeks per hanging
The only standard with a published figure behind it, and the one worth auditing. A 10ml should give you 100 presses; a 12ml hanging should run 4 to 6 weeks of continuous diffusion. If it does, the bottle has met the only number SOSA states. It fails as a standard for your actual question, which is about the cabin rather than the bottle.
A baseline you record over three like journeys
What this page argues for, because it is specific to how you drive and it is honest about being yours. One scent, one press, three similar journeys, verdict at the end rather than the start. It fails if you keep changing two things at once, which is how most informal testing goes wrong.
Whatever somebody with the windows up all journey reports
Worth hearing and not worth adopting. Their conditions are not yours, and no published figure connects the two, so their account is anecdote rather than benchmark. It fails the moment you treat it as the number your bottle should hit.
A published figure for how long it should stay noticeable
The standard most people are quietly using, and it does not exist. SOSA publishes no coverage, scent-throw, projection or persistence figure at all, so there is no number here for a bottle to come up short against. If you were told one, ask where it is published.
The format choice, and why price does not decide it
Spray or hanging - the same price, scent for scent
This is the unusual part of the SOSA car range and it makes the decision cleaner than it usually is: the spray and the hanging cost the same for any given scent - ₹449 for Jasmine, ₹479 for Lavender and Sandalwood, ₹489 for Icy Mint, ₹499 for Lemon, ₹509 for Oud, Vetiver and Sea Breeze. So you are not trading money against convenience; you are choosing between fragrance you decide to have and fragrance that is simply there. The spray is 100 sprays in 10ml and you control every one of them. The hanging runs 4 to 6 weeks in refillable glass and asks nothing of you, and its stopper is the strength control - loosen for stronger, tighten for subtler. One further practical difference that decides it for some people: 15ml refills exist for the hanging and there is no spray refill at all.
Two practical facts that bear on auditing rather than on scent. 15ml refills exist for the hanging at ₹399 to ₹449 across eight scents in refillable glass, which makes the 4 to 6 weeks of a hanging easy to track across refills; there is no spray refill at all, so a spray is replaced rather than topped up, and Orange Blossom has no refill in either form. The published placement guidance is to hang from the rear-view mirror or another well-ventilated position and to keep it off leather, fabric and the dashboard. Everything in the range is alcohol-free, phthalate-free, paraben-free and IFRA-compliant, hand-blended in small batches in Pune.
₹449 to ₹549, published at 100 sprays. Fragrance you decide to have, journey by journey - which is the format that suits a car occupied an hour or two a day.
The same price as the spray, published at 4 to 6 weeks in a refillable glass bottle. The stopper adjusts it - loosen for stronger, tighten for subtler - which is the only strength control SOSA publishes.

The thing to settle before you buy anything
A perfume adds a scent. It does not remove one.
This is the single most useful sentence on the page, and it decides whether a purchase will work or disappoint. Fragrance does not remove, neutralise, mask, eliminate or purify an odour, and it does not clean or treat the air in a cabin. It puts a scent into the air alongside whatever is already there. So if a car smelled fine in March and smells wrong in July, something in the car changed - and the honest order of work is find it, dry it, air the cabin out, and only then think about fragrance. The usual culprits are dull and physical: a floor mat that has been wet since the last downpour, a boot carpet that got soaked on a road trip, an umbrella or a pair of shoes that never came out, something in the air-conditioning. Perfume over the top of any of those makes the cabin smell of two things instead of one, which is why people describe it as having got more complicated rather than fresher. SOSA's own published note on the hanging says its longevity "depends on cabin temperature, stopper setting and how often the car is driven" - heat and use change how long a bottle lasts. They do not change what a perfume is for. Once the cabin genuinely smells of nothing in particular, the published figures are simple: a 10ml spray is 100 sprays, three months and more at one a day and fifty days at two; a 12ml hanging runs 4 to 6 weeks with a stopper that loosens for more and tightens for less; the 50ml is 500 sprays and about a year and more.
Tell SOSA how many hours a day somebody is actually sitting in the car, where it is parked and for how long, whether the windows are usually open or shut, and who else drives it - and you will be told which format and how much, including the times the honest answer is the hanging at the same price because you would rather not think about it.
There is no published figure for how long a cabin stays noticeably fragranced. Which means there is no published standard your bottle could be failing.
— Sonal Sahani, SOSA
The SOSA car fragrance range
Two questions settle almost every car fragrance decision. First: is the cabin smelling of nothing in particular, or is it smelling of something? If it is smelling of something, that is the question to answer first, because a perfume adds a scent and does not remove one - and the mats, the boot carpet and the air-conditioning come before any bottle. Second, once the cabin is neutral: how many hours a day is somebody actually sitting in it? A 25 km commute is about an hour; a field job can be four. That number decides how much of what you buy is experienced by anybody at all, because the rest of the day is a sealed cabin in a parking bay. Then: do you want fragrance you switch on, or fragrance that simply runs? The 10ml spray holds 100 sprays and does nothing until you press it; the 12ml hanging runs 4 to 6 weeks whether anybody is there or not, and its stopper loosens for stronger or tightens for subtler. They cost the same for the same scent, so price does not decide it - which is unusual, and useful.
The SOSA car range, sorted by how much it asks of you day to day
Start from how the car is used, not from what the product costs
₹449 to ₹549 across nine scents. Published at 100 sprays - 3 months and above at one a day, 50 days at two a day. A fine-mist atomizer; one spray covers the cabin
The same price as the spray, scent for scent. Published at 4 to 6 weeks of continuous diffusion in a refillable glass bottle, and the stopper adjusts it - loosen for stronger, tighten for subtler
₹1,499, published at 500 sprays and about a year and more. The honest size when you already know the routine, and the wrong one while you are still working it out
₹899 for Jasmine & Lemon or Jasmine & Lavender; ₹949 for Oud + Lemon or Sandalwood & Oud. Spray combo (2 x 10ml) or hanging combo (2 x 12ml) at the same price. Four published pairs
₹399 to ₹449 across eight scents. There is no spray refill, and Orange Blossom has no refill at all - so if refilling matters, that decides the format for you
₹3,999, or ₹4,499 for the hotel-inspired sets. A different category from a spray or a hanging, and listed here so you can rule it in or out rather than wonder
from ₹3,999
The fact that answers most of these questions is a division sum. A 10ml spray is published at 100 sprays. Somebody who sprays before each of four short daily trips empties it in about twenty-five days; somebody who sprays once a day gets the published three months and more. The 50ml is 500 sprays and about a year and more. The 12ml hanging runs 4 to 6 weeks instead, continuously, and its stopper adjusts the strength - loosen for more, tighten for less. Spray and hanging are the same price scent for scent, so the choice is genuinely about how you want to use the car rather than what you want to spend. Everything is alcohol-free, phthalate-free and IFRA-compliant, formulated for 45 degrees C heat and 85 per cent humidity, made in India. Fragrance adds a scent to a cabin; it does not remove, neutralise, mask or purify an odour and it does not clean the air - so a car that has developed a smell is a question about the car, not about the perfume.

The honest spec sheet
What the SOSA car pages publish, and what they do not
Everything below is on the live product pages. Anything not on this list is not something a page like this should state.
The published quantities - a 10ml spray is 100 sprays, stated as 3 months and above at one a day and 50 days at two a day. The 50ml is 500 sprays and about a year and more, at ₹1,499. A spray combo is 200 sprays, stated as 100 days at two a day rotating. These are the only usage figures SOSA gives.
The hanging - 4 to 6 weeks (28 to 42 days) of continuous diffusion per 12ml bottle, in refillable glass, and the stopper adjusts the strength: loosen for stronger, tighten for subtler.
Combos and the Discovery Set - four published pairs at ₹899 and ₹949, as a spray combo (2 x 10ml) or a hanging combo (2 x 12ml) at the same price. The Discovery Set is ₹699 to ₹899 for three sprays and ₹2,999 for all nine. Those nine combinations are the entire set range and none is composed to order.
Refills - 15ml hanging refills at ₹399 to ₹449 across eight scents. There is no spray refill and Orange Blossom has no refill.
The formulation - alcohol-free, phthalate-free, paraben-free and IFRA-compliant, formulated for 45 degrees C heat and 85 per cent relative humidity, made in India.
The one published sentence about what changes longevity - SOSA's hanging FAQ states that exact longevity "depends on cabin temperature, stopper setting and how often the car is driven". That is a statement about how long a bottle lasts. It is not a statement about scent-throw, intensity or coverage, and it is not extended into one here. Published placement guidance: hang from the rear-view mirror or a well-ventilated spot, and keep it off leather, fabric and the dashboard.
Not published, and therefore never stated here: any cabin-volume, cabin-size, coverage, scent-throw, projection or evaporation figure - so nothing about one body of car against another in either direction, neither that a bigger cabin needs more nor that it needs the same; any air-exchange or ventilation rate; any rate or timescale for how perception shifts during a drive; any seasonal performance claim beyond the formulation for 45 degrees C and 85 per cent humidity; any difference between a petrol, diesel or electric car; any shelf life or concentration; any health effect in either direction; any bulk rate, minimum quantity, price break or lead time. Those go to WhatsApp +91 96192 18531.
Not sure whether this is a fragrance question or a cleaning question? That is the most useful thing to settle, and it is worth one message. Tell SOSA on WhatsApp at +91 96192 18531 four things: whether the car smelled fine before and has changed, where it is parked and for how long, how many hours a day somebody is actually sitting in it, and whether the windows are usually open or shut. You will get one straight answer rather than a catalogue - including the times the honest answer is "this is a wet mat, and no perfume will fix it", or the hanging at the same price because you would rather not think about it at all. What is not on this page, because SOSA does not publish it: any cabin-volume, cabin-size, coverage, scent-throw or projection figure, and nothing about one body of car versus another in either direction; any evaporation or air-exchange rate; any rate or timescale for how perception changes over a journey; any seasonal performance claim beyond the formulation for 45 degrees C and 85 per cent humidity; any shelf life or concentration; and any bulk rate, minimum quantity or lead time. What is: 100 sprays in a 10ml and 500 in a 50ml, 4 to 6 weeks for a 12ml hanging, a stopper that adjusts it, published guidance to hang it from the mirror and keep it off leather, fabric and the dashboard, alcohol-free and phthalate-free formulations made for 45 degrees C and 85 per cent humidity, and 15ml hanging refills from ₹399 with no spray refill at all. On presentation: custom label or logo on product is the one branding option - no custom box, no printed sleeve and no insert card. Where SOSA is: an Indian fragrance house based in Pune, sending orders across India, with no shop, stockist, counter or warehouse in any other city.

ISIPCA Versailles
A note from Sonal
The message I get most often during the monsoon is some version of the same thing: "I am already using your perfume and the car still smells musty by morning." And I have learned that the worst thing I can do is sell them a bigger bottle. A perfume cannot fix a smell. It adds a scent; it does not remove one. Nine times out of ten what they describe is water - a floor mat that has been damp for a fortnight, a boot carpet that got soaked on a drive and was never pulled up, an umbrella that lives in the back. Fragrance on top of that does not make the car smell fresh. It makes it smell of two things.
So I ask people to do something unglamorous first. Pull the mats out and feel underneath them. Lift the boot carpet. Take out whatever has been sitting in there since the last downpour. Then leave the car open somewhere dry for an hour. That is it. Most of the "my perfume stopped working" messages I get are solved at that step, and the ones that are not usually turn out to be the air-conditioning, which is also not a perfume problem.
The other thing I would say, because it causes real frustration: a cabin you have just opened after it has stood in the sun all afternoon is not the cabin you will be driving in. Judging a fragrance in that first thirty seconds is like tasting soup straight off the heat. Let the air move, let it cool, close it up, and then decide. Our own product page says the hanging's longevity depends on cabin temperature, the stopper setting and how often the car is driven, and I would extend the spirit of that to how you assess any of it.
And the numbers worth holding on to, because they settle more arguments than anything I could tell you about scent. A 10ml spray is a hundred sprays. Three months if you spray once a day, about fifty days if you spray twice, and under a month if you spray before every one of four short errands. The hanging runs four to six weeks and the stopper loosens for stronger or tightens for subtler. If you stop noticing it halfway through a long drive, check with somebody who has just got in before you add more - that is how a cabin ends up over-scented.
Frequently asked questions
Should somebody who drives with the windows open judge car fragrance longevity differently?
Yes, but against a baseline you record rather than a published standard. SOSA publishes counts of supply - 100 sprays in a 10ml, 500 in a 50ml, 4 to 6 weeks for a 12ml hanging - and no coverage, scent-throw or persistence figure at all. So there is no published number that an open-window drive or a windows-up drive could be measured against. Audit the bottle against its count, and record your own experience over three similar journeys.
Is there a published figure for how long SOSA car perfume stays noticeable in the cabin?
No, and that is worth knowing before you judge anything. The published figures are counts of what you have bought: 100 sprays in a 10ml, 500 in a 50ml, 200 across a spray combo, and 4 to 6 weeks of continuous diffusion for a 12ml hanging. There is no coverage, scent-throw or projection figure anywhere in the range, so any hours-in-the-cabin number you have been given did not come from a published SOSA source.
What does SOSA actually publish about conditions and longevity?
One sentence, and its scope matters: exact longevity depends on cabin temperature, stopper setting and how often the car is driven. That is a statement about how long a bottle lasts, particularly a hanging. It says nothing about scent-throw, nothing about how strong a fragrance smells, and nothing about how long a cabin holds it. Windows are not named in it either, so nothing in it can be stretched to cover open-window driving.
How do I know whether my bottle is underperforming?
Audit it against the only published number it has. A 10ml spray should give you 100 presses; the pages set that out as 3 months and above at one spray a day and 50 days at two a day. A 12ml hanging should run 4 to 6 weeks of continuous diffusion. If the bottle meets its count, it has met the published figure, and anything else you are judging is being judged against a baseline rather than a specification.
My cabin has started smelling of something underneath the fragrance. Does that change the standard?
It changes the question entirely. Fragrance adds a scent to a cabin and does not remove one, so no baseline and no bottle will deal with a smell that has its own source. Lift the floor mats and feel underneath, check the boot carpet, take out footwear and anything damp, and look at the air-conditioning. Air the car somewhere dry, and set your baseline once the cabin smells of nothing in particular again.
Take the next step
Audit the count, then record your own baseline
Hold the bottle to the only figure SOSA publishes about it, and hold the rest to something you wrote down. That is the whole method, and it is more honest than any borrowed number - because no coverage, scent-throw or persistence figure exists anywhere in the range for anybody to quote. The formats, and the figure each one gives you to audit: the 10ml spray at ₹449 to ₹549 is 100 sprays, so three months and above at one a day and fifty days at two. The 12ml hanging at the same price per scent runs 4 to 6 weeks of continuous diffusion in refillable glass, with the stopper loosened for stronger or tightened for subtler and published advice to start it tighter. The 50ml at ₹1,499 is 500 sprays and about a year and more. And before you judge anything at all: if the cabin has started smelling of something you can name, fragrance adds a scent and does not remove one - mats up, boot carpet checked, damp things out, air through it, and your baseline afterwards.
Not sure whether this is a fragrance question or a cleaning one? Tell SOSA on WhatsApp whether the cabin smelled fine before and has changed, where the car is parked and for how long, and how long anybody is actually sitting in it. You will get one straight answer - including the times that answer is to dry the car out and buy nothing this week.

About this guide: Written by Sonal Sahani, ISIPCA Versailles-trained founder and perfumer at SOSA Home & Body. Product details reflect the SOSA range; the reasoning about moisture, parking, occupancy and ventilation applies to any brand.
Specifications verified from the live SOSA product pages, 1 October 2026: SOSA publishes nine car perfume scents. Eight are sold in two formats at the same price per scent - a 10ml spray and a 12ml hanging: Jasmine ₹449; Lavender and Sandalwood ₹479; Icy Mint ₹489; Lemon ₹499; Oud, Vetiver and Sea Breeze ₹509. Mysore Orange Blossom is spray only, ₹549 in 10ml. A 50ml spray is ₹1,499. The published quantities are: 10ml equals 100 sprays, stated as three months and above at one spray a day and fifty days at two a day; 50ml equals 500 sprays, stated as about a year and more; a spray combo is 200 sprays; and a 12ml hanging runs 4 to 6 weeks, that is 28 to 42 days, of continuous diffusion in a refillable glass bottle whose stopper loosens for stronger and tightens for subtler. Four combos are published - Jasmine & Lemon and Jasmine & Lavender at ₹899, Oud + Lemon and Sandalwood & Oud at ₹949 - each as a spray combo of 2 x 10ml or a hanging combo of 2 x 12ml at the same price, and each also in a 50ml x 2 variant at ₹2,999. The Car Perfume Sprays Discovery Set publishes eight three-scent combinations from ₹699 to ₹899 plus a pack of all nine at ₹2,999; those are the entire set range and none is composed to order. Hanging refills are 15ml at ₹399 to ₹449 across eight scents; there is no spray refill and Orange Blossom has no refill. Everything is alcohol-free, phthalate-free, paraben-free and IFRA-compliant, formulated for 45 degrees C heat and 85 per cent relative humidity, made in India. The published placement guidance is to hang from the rear-view mirror or a well-ventilated position and to keep it off leather, fabric and the dashboard. SOSA's published note on the hanging states that exact longevity depends on cabin temperature, stopper setting and how often the car is driven; that statement is about how long a bottle lasts and is not extended here into any claim about scent-throw or intensity. SOSA Safar is ₹3,999, or ₹4,499 for the hotel-inspired sets. What is not published, and is therefore not stated here: any cabin-volume, cabin-size, coverage, scent-throw, projection or evaporation figure, and consequently nothing about how one body of car compares with another - no claim that a larger cabin needs more fragrance, and no claim that it needs the same, because SOSA publishes neither and makes no body-type-specific product; any air-exchange or ventilation rate; any rate, timescale or physiological account of how perception changes across a journey; any seasonal performance claim beyond the stated formulation for heat and humidity; any difference between petrol, diesel and electric vehicles; any shelf life, expiry or concentration; and any bulk rate, minimum quantity, price break or lead time. Limits of this guide: fragrance adds a scent to a cabin. It does not remove, neutralise, mask, eliminate or purify an odour, it does not clean or treat the air, and a car that has developed a new smell is a question about the vehicle rather than about perfume. Where this guide discusses moisture, footwear, food or air-conditioning as the source of a cabin smell, that is general practical reasoning about cars and not a claim about any SOSA product. No health claim is made anywhere on this page, in either direction - nothing here states or implies that any fragrance causes or prevents a headache, nausea, motion sickness or any other effect, and nothing is said about safety in pregnancy or for children or the elderly, because SOSA publishes no information this page can rely on. No third-party brand is named and no competitor or category of competing product is characterised. No rating, review count, strength percentage or customer name from any product page is cited. Bulk orders are welcome and custom label or logo on product is available; that is the only branding option, and quantities are settled on WhatsApp. SOSA Home & Body is an Indian fragrance house based in Pune, Maharashtra, sending orders across India, with no shop, showroom, stockist, counter or warehouse in any other city.
