SODIUM TRIMETHYLPENTENE/MA COPOLYMER.

Questionable CAS 37199-81-8 / VISCOSITY CONTROLLING

SODIUM TRIMETHYLPENTENE/MA COPOLYMER is a synthetic polymer designed to enhance the textural integrity and longevity of cosmetic formulations. It primarily functions as a film-forming and binding agent, contributing to smooth application and water resistance on the skin.

Summary

film-forming binding agent viscosity controlling water-resistant properties

Science

Mechanism of Action

This copolymer operates by creating a fine, flexible film upon application, which helps to anchor other ingredients and establish a protective, water-resistant layer on the skin's surface. This mechanism improves product adherence, ensures uniform distribution, and also aids in controlling the overall viscosity of the formulation.

Safe with restrictions
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has evaluated a broad class of acrylates copolymers, including related structures, concluding their safety in cosmetics when formulated to be non-irritating. The Environmental Working Group (EWG) assesses this ingredient as having low concern for cancer, allergies, immunotoxicity, and developmental/reproductive toxicity. However, Incidecoder indicates a high irritancy potential. The ingredient is listed on the United States Toxic Substances Control Act (TSCA) Inventory.
