Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Unknown

The Cosmetic Ingredient Review (CIR) Expert Panel has not directly assessed the safety of GLYCOL/NEOPENTYL GLYCOL/PHTHALIC ANHYDRIDE COPOLYMER BENZOATE. However, related trimellitic anhydride copolymers, such as Phthalic Anhydride/Trimellitic Anhydride/Glycols Copolymer and Adipic Acid/Neopentyl Glycol/Trimellitic Anhydride Copolymer, have been deemed safe for use in nail product formulations at concentrations up to 12% and 32.8% respectively. The data were considered insufficient to determine their safety for general cosmetic applications, indicating a similar knowledge gap for this specific ingredient in skincare.

Verdict

Insufficient Data

Given the absence of a direct safety assessment by the CIR Expert Panel for this ingredient in general cosmetic applications and a lack of specific clinical efficacy data, its suitability for precision skincare formulations currently has insufficient supporting data.
