TDI/TRIMELLITIC ANHYDRIDE COPOLYMER.

Insufficient Data / BINDING

TDI/Trimellitic Anhydride Copolymer functions as a film-forming and binding agent in cosmetic formulations, creating an ultra-thin, continuous layer. This polymeric ingredient is designed to enhance product textures and may offer a protective barrier against external environmental stressors.

Summary

Film forming Binding agent

Science

Mechanism of Action

This copolymer operates by establishing a cohesive, adherent, and flexible ultra-thin film on the skin's surface. This film serves as a physical barrier, potentially reducing damage from environmental aggressors such as chemicals, UV radiation, and pollution. Additionally, its binding properties contribute to the achievement of smoother, more uniform textures within skincare formulations.

Stability

The Trimellitic Anhydride monomer, a constituent of this copolymer, undergoes rapid hydrolysis in water, completing within ten minutes. This rapid hydrolysis suggests potential stability considerations for the copolymer in water-based formulations, particularly if residual anhydride groups are present or under extreme pH conditions. However, related copolymers are generally stable under normal storage conditions and should be protected from excessive heat and moisture.

Safety

Safety Profile

CIR Status
Insufficient data
Sensitization risk Unknown

The Cosmetic Ingredient Review (CIR) Expert Panel determined that there was insufficient data to ascertain the safety of TDI/Trimellitic Anhydride Copolymer for use in any cosmetic formulations. This assessment was driven by concerns regarding its chemical definition and a fundamental lack of chemical data. While two related trimellitic anhydride copolymers were concluded to be safe in nail product formulations, this safety conclusion was not extended to general cosmetic applications for TDI/Trimellitic Anhydride Copolymer. Trimellitic Anhydride, the monomer from which the copolymer is derived, is identified as a known respiratory sensitizer, allergen, and hapten in occupational settings, with its dust capable of irritating eyes, skin, and mucous membranes. Although residual monomer levels in copolymers are anticipated to be minimal, the overall safety profile for dermal application of this specific copolymer remains undetermined.
