Formulation
Stability
Hexyl isobutyrate demonstrates robust stability under recommended storage conditions, showing good stability in alcoholic solutions, powder detergents, and soaps, with moderate stability at pH 10 and in antiperspirant sprays. However, its stability is significantly compromised at pH 2. For optimal preservation, storage in a tightly closed container, protected from light, heat, flames, and sparks, is crucial.

Safety Profile
Hexyl isobutyrate is Generally Recognized as Safe (GRAS) by the US FDA as a food additive. The JECFA found no safety concern at current intake levels for its use as a flavoring agent. The RIFM has peer-reviewed its safety, concluding it can be safely used in everyday products within current usage levels. Human experience with a 4% solution showed no irritation or sensitization. While an older European classification listed it as an irritant (Xi; R36/38) for skin and eyes, this typically refers to the neat substance. Overall, it does not meet GHS hazard criteria for 99.1% of reports.
