COCOYL HYDROLYZED COLLAGEN.

Valuable CAS 68952-15-8 / ANTISTATIC, CLEANSING, HAIR CONDITIONING, SKIN CONDITIONING, SURFACTANT - CLEANSING

Cocoyl Hydrolyzed Collagen functions as a multi-purpose skin conditioning agent and humectant, significantly enhancing skin hydration, texture, and suppleness. It is particularly valued in cleansers for its ability to mitigate the harshness of surfactants, improving overall product mildness.

Science

Mechanism of Action

This ingredient operates primarily as a humectant and skin conditioning agent, effectively binding moisture to the skin's surface. This action improves hydration, refines skin texture, enhances suppleness, and minimizes flaking. While it offers strengthening benefits that can contribute to reducing the appearance of fine lines and enhancing elasticity, its molecular size prevents direct penetration into the stratum corneum to build new collagen.

Safe as used
Max tested
20%
Sensitization risk Moderate

The Cosmetic Ingredient Review (CIR) Expert Panel has affirmed Cocoyl Hydrolyzed Collagen ingredients as safe in cosmetics under current use practices and concentrations. A maximum use concentration of 20% has been reported for Potassium Cocoyl Hydrolyzed Collagen in specific product types. However, a human repeated-insult patch test (HRIPT) involving a related variant (Potassium and TEA-Cocoyl Hydrolyzed Collagen) at 10% aqueous concentration indicated allergic contact sensitization in 2 subjects and cumulative irritation in 2 others out of 168. Strict formulation guidelines include avoiding nitrosating systems, maintaining a minimum purity of 99%, a maximum secondary amine content of 0.5%, a maximum nitrosamine content of 50 µg/kg, and storage in nitrite-free containers.
