Dusting Analysis
This ingredient is not commonly 'dusted' or misused for efficacy, as its primary roles are as a solvent or fragrance agent, not a direct active for skin benefits.
The Formula
Formulation
Stability
Isobutyl Propionate is an ester susceptible to hydrolysis in the presence of water, which can revert it to its parent alcohol and acid. It is a flammable liquid and vapor, necessitating avoidance of heat, sparks, open flames, direct sunlight, and extreme temperatures during storage and handling.

Safety
Safety Profile
Data indicates Isobutyl Propionate is classified with R38, signaling it is irritating to skin. Prolonged skin contact may induce temporary irritation, and inhalation or direct contact can irritate or burn skin and eyes. While deemed safe at current levels of intake as a flavoring agent by JECFA and listed by the FDA for this use, its direct application to skin warrants caution due to irritation potential.
