POLYACRYLATE-6.

Valuable CAS - / FILM FORMING

Polyacrylate-6 is a highly versatile synthetic polymer serving primarily as a thickening agent and emulsion stabilizer in advanced skincare formulations. It significantly enhances product texture, providing an elegant, non-sticky feel, while supporting skin barrier function and preventing transepidermal water loss.

Science

Mechanism of Action

This ingredient functions by efficiently thickening water-based systems and stabilizing various emulsion types, ensuring product consistency. It forms a protective, water-retaining film on the skin's surface, which contributes to barrier integrity and hydration. Additionally, Polyacrylate-6 can absorb excess oil and sebum, leading to a desirable matte finish, and effectively suspends insoluble particles to optimize the distribution of active ingredients.

Sensitization risk Low

The Cosmetic Ingredient Review (CIR) and the U.S. Food and Drug Administration (FDA) have both assessed Polyacrylate-6, deeming it safe for its intended use in cosmetics. Dermal irritation studies in rabbits at concentrations >90% showed no irritation, and human patch tests at ~5% indicated it is non-sensitizing. While an in vitro eye test predicted non-irritation at 2%, slight irritation was noted in rabbits at an undisclosed concentration. It is not subject to use restrictions in the European Union.
