The Formula
Formulation

No specific optimal pH range for stability has been identified. It is soluble in alcohol and fixed oils. Water solubility is estimated at 356.7 mg/L at 25 °C, making it poorly soluble, and it is listed as insoluble in glycerin and propylene glycol.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) has not specifically evaluated Isononyl Propionate, a compound distinct from Isononyl Isononanoate which is sometimes referenced erroneously. It generally demonstrates a low hazard profile according to GHS criteria, with 114 out of 114 reporting companies not classifying it as hazardous. Neither the SCCS nor the FDA has issued specific opinions or approvals for this ingredient as a cosmetic, though it is an active chemical under EPA TSCA.

Verdict
While Isononyl Propionate exhibits a low general hazard profile, the lack of specific cosmetic safety assessments (CIR/SCCS) and dedicated skin-related efficacy data means its precise role and safety profile in precision skincare remain largely undefined.
