Profile

Isovaleric Acid is curated in this catalog as a feral material, with a secondary reading of barnyard.

On the strip it reads Cheesy sweaty animalic note.

It is registered under CAS 503-74-2.

How it behaves

volatility index 0.78 · the opening

A boiling point of 175 °C and a molecular weight of 102.13 g/mol give Isovaleric Acid a volatility index of 0.78, 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 Isovaleric Acid

What does Isovaleric Acid smell like?

Isovaleric Acid reads as feral and barnyard, described in the catalog as Cheesy sweaty animalic note.

Is Isovaleric Acid a top, heart or base note?

Isovaleric Acid sits in the opening. Its volatility index of 0.78 is computed from a boiling point of 175 °C and a molecular weight of 102.13 g/mol, rather than assigned by hand. It leaves the strip early and does its work in the first minutes, before the heart arrives.

What can I use instead of Isovaleric Acid?

The closest materials in this catalog by olfactive profile and physical behaviour are Para Cresyl Methyl Ether (60.3% match), Valspice (4 Methyl Guaiacol) (Natural) (57.1% match) and Massoia Lactone (56.9% match). Closeness is scored on descriptor taxonomy and on measured properties, so the nearest match is the one that behaves most like Isovaleric Acid. Ranking ignores price.
