TIPA-ACRYLATES/ETHYLHEXYL ACRYLATE COPOLYMER.

Valuable / FILM FORMING

This copolymer serves as a versatile film-forming agent, creating a resilient, invisible layer on the skin. It significantly enhances product durability and spreadability, imparts water-resistant qualities, and contributes to a smooth skin feel.

Summary

Film forming

Science

Mechanism of Action

Upon application, TIPA-ACRYLATES/ETHYLHEXYL ACRYLATE COPOLYMER forms a polymeric film on the skin's surface. This barrier mechanism extends the longevity of cosmetic formulations, prevents issues like smudging or flaking, and facilitates the even distribution of product. Furthermore, this film helps anchor active ingredients on the site of application, potentially optimizing their efficacy and offering enhanced water resistance.

Stability

Initially insoluble in water, this copolymer becomes water-soluble or dispersible upon 100% neutralization of its carboxyl groups with appropriate water-soluble bases (e.g., triethanolamine, potassium hydroxide). Alternatively, it can be solubilized into oil systems through full neutralization with long-chain amines. While its monomer, 2-ethylhexyl acrylate, polymerizes easily, the copolymer itself is a stable, high-performance ingredient.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that this copolymer, alongside other related acrylates, is safe for use in cosmetics within current practices and concentrations, provided formulations are non-irritating. The CIR report notes that related copolymers may contain residual 2-ethylhexyl acrylate at 100 to 1000 ppm. Studies on the monomer 2-ethylhexyl acrylate indicate it is not genotoxic but caused skin cancer in C3H mice at high, irritating concentrations (21%, 43%, and 83%), with the mechanism linked to chronic irritation. However, lower concentrations (2.5%) were not found to be carcinogenic, emphasizing that the stable copolymer is safe under normal usage conditions.
