Profile

Thymol is curated in this catalog as an aromatic material, with a secondary reading of herbal.

On the strip it reads warm thyme medicinal phenolic.

It is registered under CAS 89-83-8.

The catalog records an average working dose of 0.5% Max%, which is a starting point for a trial rather than a limit.

How it behaves

volatility index 0.64 · the opening

A boiling point of 231.5 °C and a molecular weight of 150.221 g/mol give Thymol a volatility index of 0.64, which places it in the opening of a composition.

It leaves the strip early and does its work in the first minutes, before the heart arrives.

The index runs from 0 for a material that barely leaves the strip to 1 for one that flashes off, and it is computed from boiling point and molecular weight. Inside a real formula the surrounding materials shift where the boundaries fall, so a material can read differently there than it does here.

Questions about Thymol

What does Thymol smell like?

Thymol reads as aromatic and herbal, described in the catalog as warm thyme medicinal phenolic.

Is Thymol a top, heart or base note?

Thymol sits in the opening. Its volatility index of 0.64 is computed from a boiling point of 231.5 °C and a molecular weight of 150.221 g/mol, rather than assigned by hand. It leaves the strip early and does its work in the first minutes, before the heart arrives.

How much Thymol should I use?

The catalog records an average working dose of 0.5% Max% for Thymol. Treat that as the starting point for a trial: the right dose depends on what else is in the formula and what you want it to do there.

What can I use instead of Thymol?

The closest materials in this catalog by olfactive profile and physical behaviour are Carvacrol (100% match), Lavender Aldehyde FCC - Bedoukian (99.7% match) and Carvone-L (82.3% match). Closeness is scored on descriptor taxonomy and on measured properties, so the nearest match is the one that behaves most like Thymol. Ranking ignores price.

What is the CAS number for Thymol?
