SOSA · The Complete Car Ritual · Mystery & distinction
The first scent a new car should know. Assam Oud, the complete ritual.
Every new car deserves a scent that makes it feel like theirs. This is the whole Assam Oud ritual in one order: a hanging diffuser that keeps the cabin quietly scented every day, a refill for the month after, a 10ml spray for the glove box and a 50ml spray to keep at home. A warm, resinous agarwood inspired by the oud of Assam, composed by perfumer Sonal Sahani in Pune. The gift for someone who has just brought home a new car, or for yourself.

II. For a new car
A new car is an occasion
In India, a new car is never just delivered. It is taken to the temple, garlanded across the bonnet, blessed with a nimbu-mirchi and a coconut broken at the wheel. The whole family comes for the first drive.
Then, for weeks, it smells of new plastic and upholstery. The ritual changes that. From the first drive, the car smells of something chosen, something that is theirs. Every time they open the door, they will think of who gave it to them.
The first scent of a new car, and the one it is remembered by.
Give it to
- Someone who has just bought their first car
- Parents bringing home the new family car
- A newly married couple and their first car together
- A colleague, client or friend: a gift used every single day

V. Heritage विरासत
Oud, and why Assam
Oud comes from the agarwood tree. When the wood is wounded, it slowly fills with a dark, fragrant resin, and that resinous heartwood is what the world calls oud. It has been worn by Mughal emperors and traded across oceans for centuries.
The resin of the northeast, softened for the drive.
“Oud is easy to make loud, and in a small car, loud becomes heavy within minutes. I kept the resin and the warmth of agarwood and took away the smoke, so it reads like the inside of a carved wooden box, not an incense shop.”Sonal Sahani · Perfumer's note

How to use
- Hang the diffuser from the rear-view mirror, clear of the dashboard. Once a week, turn it upside down for a moment so the oil soaks the wooden lid.

- Keep the 10ml spray in the glove box. Spray once toward the centre of the cabin, away from seats and leather, and add a second spray when you want it fuller.

VIII. Questions
Is this pure oud oil?
No, and we'd rather say so. Pure distilled oud costs thousands of rupees for a few millilitres. This is an agarwood blend composed to capture the warmth of Assam oud.
Will oud be too heavy for a closed car?
No. It is built for a closed AC cabin: warm and resinous, without smoke, and it settles close rather than filling the car.
Is this a good gift for someone with a new car?
It is the gift we would give. A new car is used every day, so a gift for it is noticed every day. The set has everything for the first few months: the hanging diffuser for daily scent, a refill for the next month, a 10ml spray for the glove box and a 50ml spray to keep at home. All in Assam Oud, composed in our Pune studio.
Which scent should I choose for someone else?
Think about how they like their home to smell. Fresh and light: Malabar Lemon, Icy Mint, Sea Breeze. Warm and familiar: Mysore Sandalwood, Khus Vetiver. Deep and evening: Assam Oud. Soft and floral: Mogra Jasmine, Bhaderwah Lavender. If you are unsure, a fresh scent is the easiest choice for a car the whole family shares.
How long does the set last?
The hanging diffuser lasts 4 to 6 weeks, and the refill fills it completely for another 4 to 6 weeks, so roughly two to three months of everyday scent. On top of that, the two sprays give about 600 sprays between them.
Why both a hanging diffuser and sprays?
They do different jobs. The hanging diffuser is soft and always on, so the car never smells of nothing. The sprays are fuller and on demand: before a guest gets in, after lunch, at the end of a long day. Together they are the whole ritual.
Why is there alcohol in the spray?
The spray uses perfumer's alcohol, the traditional base of fine fragrance. It carries the scent into the air as a fine mist and evaporates within seconds, so what stays in your car is the fragrance, not the alcohol. Spray toward the centre of the cabin, away from seats and leather. If you prefer something softer and slower, the hanging diffuser in this set releases the scent gradually over weeks.
Does it work in monsoon and summer heat?
Yes. In May 2026, in Pune, we ran it through a 72-hour test in sealed parked cars, with heat up to 45°C and humidity up to 85% RH. Our internal panel rated scent stability and intensity, and the character held steady across the test. This was our own product testing, not a clinical study.
Will it give anyone a headache? Some of us are sensitive to fragrance.
It's composed to stay soft in a closed car: you notice it without it filling the cabin. It's IFRA-compliant and made to be gentle. If anyone in the car is pregnant, has asthma or a known fragrance sensitivity, check with a doctor before using any fragrance in a closed car, start with a single spray and keep the car ventilated.
How long does shipping take?
Orders ship the next working day and arrive in 3 to 5 days, depending on where you are.
