Straight answer
What fragrance five-star hotels actually use
Five-star hotels use proprietary signature scents - fragrances commissioned privately to represent each brand, diffused through their spaces, and often different from one property to the next. So the honest first half of the answer is: the exact formulas are not for sale, and no one can truthfully hand you the literal scent of your favourite hotel. But the second half is not a secret at all. The note families luxury hotels reach for are remarkably consistent, because they all chase the same feeling of clean, understated luxury: white tea (by far the most iconic - the famous Westin white-tea signature made this a whole category), green tea, citrus and bergamot, a little fig, and soft woods like cedar and sandalwood with a touch of amber. Nothing sweet or loud - it is quiet luxury in a bottle. That is why you can get so close at home: a hotel-inspired fragrance built on those same families, run through a water-based diffuser, gives you the character without the proprietary formula. SOSA's White Tea Serenity and Quiet Luxury are built on exactly those notes. It is a water-based fragrance, not a masking spray - this is not reed diffuser oil - from ₹299. (SOSA is independent and not affiliated with the hotels named.)
One line: the exact formulas are proprietary, but the notes are no secret - white tea, green tea, citrus, fig, cedar, sandalwood and amber.
A lovely place to start is White Tea Serenity - white tea, aloe and cedar, from ₹299. Add a few drops to your diffuser and the room shifts.

What actually sets the mood
The answer has an honest limit and a useful open secret. Here is exactly what five-star hotels use, what you cannot get, and what you can.
1
The secret part
The exact formulas are proprietary
Luxury hotels commission signature scents privately - composed for the brand, kept confidential, and sometimes varied by property. So the literal formula is not something you can buy, and anyone claiming to sell the exact hotel scent is overpromising. That is the honest limit worth knowing before you shop.
Tip: be wary of any product promising the exact hotel formula - the real, honest goal is the same notes and feeling.
2
The open secret
The note families are well known
What is not secret is the palette. Five-star hotels reach again and again for white tea, green tea, citrus and bergamot, fig, cedar, sandalwood and soft amber - clean, understated notes that read as expensive. The white-tea family is the most iconic of all, made famous by a well-known hotel signature and copied ever since. Master those notes and you have the hotel feeling.

How to get those notes
A hotel-inspired fragrance in a diffuser
You cannot buy the formula, but you can buy a hotel-inspired fragrance built on the same note families and diffuse it the hotel way. SOSA's White Tea Serenity (clean white tea) and Quiet Luxury (white tea, bergamot and cedar) are composed on exactly those notes - run them soft and continuous in a water-based diffuser and you are very close.
Tip: choose a scent built on white tea, citrus and soft woods - that is the five-star palette in a home fragrance.
The SOSA principle
You cannot buy the exact hotel formula - but the notes they use are no secret at all.
White tea, green tea, citrus, fig, cedar, sandalwood, amber - clean and understated, chosen for the same quiet-luxury feeling. Get those notes into a diffuser and you have what makes a five-star hotel smell the way it does.
Which scent, and how to use it
Here is how the Hotel Collection maps to the note families five-star hotels actually favour, so you can pick the one closest to what you loved.

A note from Sonal
As a perfumer, the hotel question I get most is what do they actually use. The truth is the formulas are private - but the notes never were, and once you know them, the hotel feeling is yours to build.
So I composed the Hotel Collection - seven water-based diffuser fragrances, each our own interpretation of the signature scent a great hotel is known for. They are made to run cleanly through an ultrasonic diffuser, not to sit in reeds. This is not reed diffuser oil; it is a water-based fragrance you add a few drops of to the tank.
One honest note: fragrance sets the mood, it does not fix a stuffy or damp room - open a window and clear the air first, then let the scent do the quiet, expensive work. A little goes a long way, so start with a few drops and build up to taste.
