Founder Diaries · Attars & Perfume Oils
By Sonal Sahani · ISIPCA Versailles 9 min read Updated 2026
Almost every fragrance decision comes down to three properties, and most people confuse them. Longevity is how long it lasts. Projection is how loud it is. Sillage is the trail it leaves as you move. Once you can tell them apart, choosing an attar stops being guesswork — you just match the one you care about most to the right scent. Here's the full map.
Quick answers — read this first
What's the difference between projection, longevity and sillage? Longevity = how many hours it lasts on skin. Projection = how far it radiates outward at any moment. Sillage = the scent trail you leave behind as you walk. A scent can be long but quiet, or loud but short — they're independent.
Which SOSA attar is best on each? Longevity: Nawaab. Projection: Nawaab (worn generously). Quiet, elegant sillage: Adaa or Mastani. Balanced warmth: Ameeri. Match the property you care about most to the scent.
Which property should I prioritise? For daily and office wear, prioritise longevity and a tight sillage. For evenings and events, prioritise projection. Oils naturally favour longevity and close sillage — that's the family's strength.
The short answer
Short answer: Decide which of the three matters most to you, then match it. Want it to
last?
Nawaab or
Ameeri. Want it to
project? Nawaab, worn generously. Want a quiet, elegant
trail?
Adaa or
Mastani. As a family, attars favour longevity and close sillage over loud projection — so if those are your priorities, you're in exactly the right place. The performance box below maps every choice.
Best pick: for longevity and projection, the
Nawaab attar (oud & saffron, from ₹399); for a fresh, subtle daily signature,
Adaa (from ₹379). Every attar is a 3/6/12ML roll-on.

Straight answer
How do I turn these three words into an actual purchase?
Rank the three for your life: be honest about which matters most. Most daily wearers want longevity first and a tight sillage second; event-focused buyers want projection first.
Match to a hero: longevity → Nawaab/Ameeri; projection → Nawaab worn generously; quiet sillage → Adaa/Mastani. The box below lays each out.
Then test on your own skin: all three properties shift with your chemistry, the weather and how much you apply. Give any attar ten minutes on skin before judging where it lands.

Longevity = how long. Projection = how loud. Sillage = the trail. Rank them for your life, then match: Nawaab to last and project, Adaa/Mastani for a quiet trail, Ameeri for balance.
The three properties, clearly defined
1
Longevity
How long it lasts
SOSA Nawaab · White Oud & SaffronFrom ₹399 Longevity is simply hours on skin, and it lives in the heavy base notes — oud, saffron, sandalwood, amber.
Nawaab leads here;
Ameeri's sandalwood is a close second. Oils as a family win on longevity because concentrated oil releases slowly, so this is the property attars are strongest on.
Tip: Moisturised skin extends longevity for any attar — dry skin is the biggest thief of hours.
2
Projection
How far it radiates
SOSA Attar Trio · pack of 3₹1,055 Projection is how far the scent travels off your skin right now — the 'presence' in a room. It's driven by bold notes and, in sprays, by alcohol. Among oils,
Nawaab projects hardest; the rest sit closer by design. Remember the honest trade: oils favour longevity over big projection.
Tip: You control projection through how much you apply and how warm the points are — more, warmer = louder.
3
Sillage
The trail you leave
SOSA Adaa · Bergamot & JasmineFrom ₹379 Sillage is the scent trail behind you as you move — separate from projection, which is your radius standing still. A tight, elegant sillage is a signature;
Adaa and
Mastani do this beautifully, present to those near you without broadcasting. This close, refined trail is a hallmark of oils.
Tip: For an intimate sillage, apply to fewer points; for a bigger wake, add the neck and inner elbows.
Maximum longevity & projection SOSA Nawaab From ₹399 Nawaab (White Oud & Saffron) is the powerhouse of the range - a deep, resinous oud-saffron base that holds on skin for hours and projects for the first stretch of an evening. If longevity and presence are your priority, start here. Sizes 3ML (₹399), 6ML (₹699), 12ML (₹1,199). See Nawaab →
Why these three don't move together — and why oils change the rules
The single most useful thing to understand is that longevity, projection and sillage are independent. A fragrance can last twelve hours and stay whisper-quiet the whole time (long, low projection). Another can announce itself across a room and be gone in three hours (loud, short). A third can leave a gorgeous trail as you pass but be almost undetectable when you're standing still. People who say a perfume 'didn't perform' usually mean it failed on the one axis they cared about — while quietly succeeding on another they weren't measuring.
In alcohol sprays, these three tend to rise and fall together because alcohol drives both projection and the speed of the burn. Oils break that link, which is exactly what makes them worth understanding. A concentrated attar naturally maximises longevity and keeps sillage close and refined, while trading away some raw projection. So if you rank longevity and an elegant trail above room-filling loudness — which most people, on reflection, do — an oil isn't a compromise. It's the format that optimises for the properties you actually value.

The SOSA principle
People don't disagree about which perfume is 'best' — they disagree about which of the three properties they were measuring. Name your priority and the choice makes itself.
Longevity, projection, sillage: rank them honestly, and the right attar is obvious.
Fresh, subtle & office-friendly SOSA Adaa From ₹379 Adaa (Bergamot + Cardamom + Jasmine Sambac) is the daytime-grace choice - clean, fresh, and sitting close to the skin, so it lasts without filling a shared room. The right pick for AC offices, hot-humid days and anyone who prefers a quiet signature. Sizes 3ML (₹379), 6ML (₹669), 12ML (₹1,149). See Adaa →
Longevity is how long, projection is how loud, sillage is the trail. Learn those three words and you'll never buy the wrong fragrance again.

How to read this box: attars are concentrated perfume oils, so as a family they wear
longer and closer to the skin than alcohol sprays - you trade some room-filling projection for longevity and a refined, intimate trail. For the most presence,
Nawaab (oud & saffron) projects hardest and lasts longest; for a clean daytime signature that won't overwhelm a shared cabin,
Adaa is the pick. Every attar comes as a 3ML pocket roll-on (from ₹379) that's effortless to reapply, plus 6ML and 12ML. Scent behaves differently on every person and in every climate, so give it ten minutes on your skin before you judge it, and layer on pulse points for more strength. Everything is made in India; a portion of every order supports girl-child education through Nanhi Kali.
Why a roll-on oil Long wear, easy reapply From ₹379 An attar is concentrated perfume oil: it wears longer and closer to the skin than an alcohol spray, and the roll-on format is spill-proof and pocketable - the 3ML slips into a bag for touch-ups. Oils lean toward longevity and intimacy over big room-filling projection; for maximum projection, layer or choose the deeper Nawaab. Shop the range →
A note from Sonal
Everything is made and supported from Pune, and a part of every order funds girl-child education through Nanhi Kali. You get a fragrance that lasts; a girl gets a classroom. That equation has always felt right to me.
Frequently asked questions
If I can only optimise one, which should it be?
For most people, longevity — a scent that fades by lunch fails you no matter how it opened. Oils are strongest here, which is why an attar suits daily wearers so well. Prioritise projection only if your wear is event-driven.
Is high projection always better?
No — it's often worse. In an office or a crowded room, strong projection works against you, and it usually fades faster too. A tight, elegant sillage with strong longevity is the more versatile, more sophisticated profile, and it's where oils shine.
Do these ratings hold on everyone's skin?
They're the honest tendencies of each scent, but your chemistry, the climate and your application all shift where a fragrance lands on the three axes. Treat the grid as a starting map and confirm it with a day on your own skin.

Editorial standards & sources
About this guide: Written by Sonal Sahani, ISIPCA Versailles-trained founder and perfumer at SOSA Home & Body. Fragrance performance - longevity, projection and sillage - depends on the perfume, but also on your skin type, body chemistry, the weather and how much you apply, so descriptions here are honest guidance, not guarantees. Attars are concentrated perfume oils: they generally wear longer and closer to the skin than alcohol-based EDPs, trading some projection for longevity and intimacy. Always test on skin and give a fragrance ten minutes to settle before judging it; patch-test if you have sensitive skin, and keep oils away from the eyes.
