Safety
Safety Profile
Phenoxyethyl isobutyrate holds GRAS (Generally Recognized As Safe) status and FDA approval for food applications. The Scientific Committee on Consumer Safety (SCCS) of the European Commission indicates a lack of human data concerning contact allergy for this substance. The Research Institute for Fragrance Materials (RIFM) has conducted toxicological and dermatological reviews specifically for its use as a fragrance ingredient. A 13-week subchronic rat dermal toxicity study demonstrated no treatment-related adverse effects at concentrations up to 50% (1000 mg/kgBW/day), with no-observed-effect-levels (NOELs) for local skin irritation and systemic toxicity determined to be greater than 1000 mg/kgBW/day.
