The Formula
Formulation

The ingredient demonstrates heat tolerance, yet it is recommended to incorporate it as a final step in formulation, avoiding temperatures exceeding 40°C. For storage, maintaining temperatures between 15–25°C, protected from heat and light, ensures a shelf life of 24 months.
Safety
Safety Profile
No specific Cosmetic Ingredient Review (CIR) assessment has been conducted for P-CRESYL ISOBUTYRATE. Despite raw material hazard statements indicating potential irritation to eyes, respiratory system, and skin, human experience with a 4% solution demonstrated no irritation or sensitization. It is generally considered safe for cosmetic use within recommended concentrations. Note that the FDA has withdrawn approval for its synonym, p-tolyl isobutyrate, as a synthetic flavoring substance, which is irrelevant to its cosmetic application.
