An absence, honestly reported
I cannot date your bottle for you and neither can the product record. What I can do is tell you that no shelf life is published, say why that matters, and hand you the two checks you can run yourself this evening.
I would rather this page annoy you than date your bottle for you. Any figure I gave you would be about my materials and my cupboard rather than about yours, and it would be read as official because it was written down. The date on the label is the only honest instrument here, and it only works if somebody wrote it.

The answer in 30 seconds
My refill oil has been open for months. Is it still good?
- In one line. No shelf life and no expiry date is published for the refill oil, so no page can date your bottle. Smell it, look at it, and take what you find as an observation rather than as a verdict.₹1,049
- The short answer. SOSA publishes no shelf life, no expiry date and no degradation figure for the nebuliser refill oil, so nothing published can tell you whether months of being open has changed yours. What you can do is smell it beside a sealed bottle and look at the oil in daylight. Refills are Rs 1,049 for 100 gm.
- If you only do one thing: write the date on the next bottle you open. The reason this question is hard is that nobody wrote a date down, and that is the one part of it you can fix with a marker pen.
- Does SOSA publish a shelf life? No. There is no shelf life, no expiry date and no degradation figure on the record for the refill oil, so no honest page can give you one.
- Is my bottle still good, then? Nobody can answer that from the record. What you can do is smell it and look at it, and take what you find as an observation rather than as a verdict.
- What if I am not sure? WhatsApp +91 96192 18531 is the published route. Describe the bottle, say how long it has been open, and say what it smells like now.
The answer, in full
The answer starts with an absence. SOSA publishes no shelf life for the refill oil, no expiry date on it, and no figure or statement about how an opened bottle changes over months. I have read the record and it is not there. That means nobody can tell you from published information that your bottle is as it was, and it also means nobody can tell you that it is not. What you can do is look at it yourself, which is a different kind of answer and the only honest one available. Put a drop on a strip of paper and smell the strip rather than the neck of the bottle, and if you have a bottle you have not opened, smell the two one after the other. Then hold the oil up in daylight against something white. If you find a difference, you have found a difference, and what it means is not published either, so it is a reason to ask SOSA on WhatsApp at +91 96192 18531 rather than a verdict you can act on.

What is not published, what you can check, and what a check proves
The first of these is the reason the page exists, the second is what is left when the record says nothing, and the third is the limit on what your own nose can settle.
Not published: no shelf life and no expiry date
There is no shelf life on the record, no expiry date, no best-before and no figure for how a pure oil changes once the cap has been off. SOSA publishes the price and the weight, ₹1,049 for 100 gm and ₹1,849 for 300 gm, and that is where the record stops. A page that told you six months was fine, or that it was the end of the bottle, would have invented the figure and you would plan around it.
The record carries a price and a weight, and no date.
What you can check: your own nose, and daylight
Two checks, and both are free. Put a drop on a paper strip and smell the strip, because the neck of a bottle smells of the neck of a bottle. If you have an unopened bottle of the same scent, smell them one after the other and the comparison does the work for you. Then hold the oil up in daylight against something white and look at the colour and the clarity. Write down what you find, with today's date beside it.
What a check proves: a difference, and not a verdict
This is the part most pages skip. SOSA publishes nothing about what a change in colour or in smell would mean, so noticing one does not entitle me to tell you the oil has turned, and noticing nothing does not entitle me to tell you it is as it was. You have an observation. If it matters enough to have brought you to this page, the published route is WhatsApp +91 96192 18531, and what you can see and smell is exactly the useful thing to send.
An observation beats my guess and loses to SOSA's answer.
Does it depend on which scent is in the bottle?
Nothing published says so. SOSA publishes a pyramid for each of the nine scents and no ranking across them, and it publishes no per-scent shelf life because it publishes no shelf life at all. So the answer is the same for a bottle of one as for a bottle of another: look at it, smell it, write it down, and ask if it matters to you.
If the bottle in front of you has become a question, a sealed one beside it is the comparison that answers it. The nebuliser refill oil is ₹1,049 for 100 gm and ₹1,849 for 300 gm. See the nebuliser refill →
What is published, and what your own check can settle
| What the record says | |
|---|---|
| A shelf life or an expiry date | Not published. No date of any kind exists on the record for the refill oil, so this page gives you none. |
| What happens to an opened bottle | Not published either. There is no degradation figure and no statement about it, in either direction. |
| Your own nose, against a sealed bottle | This is what you actually have. It gives you a difference or no difference, on today's date, in your own bottle. |
| What that difference means | Unpublished. An observation is not a verdict, which is why WhatsApp +91 96192 18531 is the next step rather than this page. |
If the whole of this page reads as a refusal, that is because two thirds of it is one. The third that is not a refusal is the part you can do this evening, and it ends with something written on a label.
“No shelf life is published, so no page can date your bottle. Your own nose can tell you that something is different. It cannot tell you what that means.”
Checking an opened bottle, in four steps
- Put a drop on a paper strip and smell the strip, not the neck.
- Smell it beside a sealed bottle of the same scent if you have one.
- Hold the oil up in daylight against something white.
- Write down what you found and the date, then ask on WhatsApp.

Smell it, look at it, then ask
No shelf life is published, so the record cannot date your bottle. A sealed bottle beside it is the comparison that can, and WhatsApp is where the rest of the answer lives.
