III. 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

VI. 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.
How long does it last?
4 to 6 weeks, depending on heat and how often you drive. Turn the bottle upside down once a week to keep the lid fresh.
Spray or hanging?
The hanging diffuser is soft and always on. The spray is fuller and you decide when. Many people use both, which is why we make The Complete Ritual.
Can I refill it?
Yes. The bottle is refillable glass, and 15ml refills are available. One refill fills it completely.
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 me a headache? I'm 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 you're pregnant, have asthma or a known fragrance sensitivity, check with your doctor before using any fragrance in a closed car 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.
Do you offer returns or replacements?
If it arrives damaged or faulty, we'll replace it. Email service@sosahomeandbody.com within 48 hours of delivery with a photo.
