ACRYLOYLOXYETHYL TRIMONIUM CHLORIDE.

Avoid CAS 44992-01-0 / NOT REPORTED

ACRYLOYLOXYETHYL TRIMONIUM CHLORIDE is a cationic monomer primarily utilized in the synthesis of polymers, such as Acrylamidopropyltrimonium Chloride/Acrylamide Copolymer. In its polymerized form, it contributes to a desirable velvety skin feel and extended moisturization, functioning as a conditioning agent.

Science

Mechanism of Action

This ingredient operates through its intrinsic cationic nature, enabling electrostatic interactions with negatively charged biological surfaces and molecules. While the monomer itself is not typically applied directly, its polymeric forms can create a protective barrier on the skin, thereby reducing transepidermal water loss and enhancing hydration. It also acts as a conditioning agent, a viscosity modifier, and possesses surfactant properties that improve the wetting and spreading characteristics of cosmetic formulations.

Stability

ACRYLOYLOXYETHYL TRIMONIUM CHLORIDE is chemically stable under standard ambient conditions but is sensitive to heat and prone to uncontrolled polymerization, requiring an inhibitor during storage. Refrigerated storage at 2-8°C is recommended. At pH values exceeding 6.0, the ingredient undergoes significant hydrolysis, with over 70% degradation occurring within 28 days.

Our Assessment

Verdict

Avoid

Given its status as an unreviewed ingredient by CIR and its classification with multiple severe hazard statements (H302, H315, H317, H319) indicating high irritation and sensitization potential, this raw monomer is not recommended for use in precision skincare formulations.
