PHTHALIC ANHYDRIDE/BUTYL BENZOIC ACID/PROPYLENE GLYCOL COPOLYMER.

Questionable / FILM FORMING, VISCOSITY CONTROLLING

This copolymer serves as a multifunctional film-forming agent, creating a protective layer that helps lock in moisture and protect the skin. It also improves cosmetic formulation texture and stability, contributing to a smooth and refined finish in various products.

Film-forming agent Viscosity enhancing agent Binder

Science

Mechanism of Action

Primarily, this ingredient functions as a film-forming agent, depositing a thin, continuous layer on the skin or hair surface. This polymeric film provides a barrier against environmental aggressors, aids in moisture retention, and imparts a smoothed, glossy aesthetic. Furthermore, it acts as a viscosity enhancing agent and binder, contributing to the structural integrity and textural optimization of cosmetic formulations.

Safety Profile

CIR Status
Not reviewed
Sensitization risk Moderate

A direct, comprehensive safety assessment for PHTHALIC ANHYDRIDE/BUTYL BENZOIC ACID/PROPYLENE GLYCOL COPOLYMER by the Cosmetic Ingredient Review (CIR) is not available. While structurally related 'Trimellitic Anhydride Copolymers' have been classified as Polymers of Low Concern (PLC) for specific applications like nail products, data for broader non-nail cosmetic uses are deemed insufficient to establish definitive safety. Importantly, case reports of allergic contact dermatitis have been linked to similar copolymers, such as 'Phthalic Anhydride/Trimellitic Anhydride/Glycols Copolymer', affecting sensitive areas including the neck, face, and eyelids.

Our Assessment

Verdict

Questionable

While offering benefits as a film-forming and texture-enhancing agent, the absence of a direct safety review and documented allergic contact dermatitis for related compounds suggest a cautious consideration for its inclusion.
