Dusting Analysis
Isoamyl Butyrate is not typically considered a 'dusted' ingredient, as its sole purpose is to provide fragrance. Its inclusion directly aligns with the intent to create a scented product; therefore, it fulfills its specific function without being an inactive filler.
The Formula
Formulation
Stability
Isoamyl Butyrate demonstrates general stability under standard storage conditions. However, it is susceptible to degradation via hydrolysis, a reaction catalyzed by both acidic and basic environments, which yields isoamyl alcohol and butyric acid. For optimal stability, storage in tightly sealed containers in a cool, dry place, away from heat and light, is recommended.

Safety
Safety Profile
Extensive safety evaluations by the Research Institute for Fragrance Materials (RIFM) have concluded that Isoamyl Butyrate does not pose concerns for skin sensitization, photoirritation, or photoallergenicity at current usage levels. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) established a group Acceptable Daily Intake (ADI) of 0-3 mg/kg body weight for flavoring uses, finding no safety concern at current intake levels. The US FDA recognizes it as safe for specific food uses, and for cosmetics, it does not require pre-market approval for ingredients other than color additives.
