Surfactant Cleansing Agent Foam Texturizer Skin Conditioning Hair Conditioning Antistatic Antioxidant Moisture-Retentive

Science

Mechanism of Action

SODIUM COCOYL HYDROLYZED SOY PROTEIN effectively functions as a surfactant, cleansing agent, and foam texturizer, while simultaneously providing significant conditioning benefits. Its hydrolyzed soy protein component, rich in glutamic and aspartic acids, forms a protective, moisture-retentive layer on the skin. On the skin, it leverages the antioxidant properties of isoflavones to combat photoaging, stimulate cell renewal, and reduce both epidermal thickness and skin roughness. It actively promotes the production of hyaluronic acid and collagen, addressing fine lines, wrinkles, and overall skin elasticity for a plumper, firmer, and more youthful appearance. In hair care, it reduces electrostatic charges, contributing to increased shine, softness, and manageability. Furthermore, this ingredient is notable for its ability to decrease the irritation potential of formulations when paired with anionic surfactants.
