In short

Geranyl isovalerate is the isovaleric ester of geraniol. JECFA describes it as a colourless to pale yellow liquid with a rose odour.

What Geranyl Isovalerate smells like

JECFA, as published by PubChem, describes geranyl isovalerate as a colourless to pale yellow liquid with a rose odour. PubChem links it to natural-product databases. Sigma-Aldrich's food-grade listing describes it differently, as apple, blueberry, green, fruity and pineapple.

What makes Geranyl Isovalerate distinctive

A heavier geranyl ester whose published description is simply rose.

Where the descriptions disagree: JECFA gives a rose odour, while Sigma-Aldrich's listing is wholly fruity — apple, blueberry and pineapple — with no rose.

How Geranyl Isovalerate is used

JECFA evaluates it as a flavouring agent, and Sigma-Aldrich sells a food-grade grade with a fruity profile. In perfumery it softens rose and fruity-floral accords, where its rose (in JECFA's description) and apple-pineapple fruitiness (in Sigma-Aldrich's) both play.

Typical role: modifier (used in small amounts to change the character of a blend).

How Geranyl Isovalerate differs from similar materials

Geranyl Butyrate
Geranyl butyrate is described as fruity and rose-like; geranyl isovalerate simply as rose.

Each difference compares the published descriptions of the two materials. Smell varies with grade, supplier and dilution; compare them side by side on blotters before substituting one for another.
