POTASSIUM COCOYL HYDROLYZED KERATIN.

Valuable CAS - / HAIR CONDITIONING, SKIN CONDITIONING, SURFACTANT - CLEANSING

Potassium Cocoyl Hydrolyzed Keratin is a sophisticated conditioning agent derived from keratin, expertly designed to enhance skin health. It actively preserves moisture, promotes a soft and smooth complexion, and strengthens the skin's protective barrier. This ingredient also functions as a gentle surfactant, ensuring optimal product spread and cleansing efficacy.

Science

Mechanism of Action

This ingredient delivers multifaceted benefits to the skin through its unique molecular properties. It acts as both a humectant, efficiently drawing and binding water to the stratum corneum, and an occlusive, forming a delicate film on the skin's surface to minimize transepidermal water loss. Its hydrolyzed nature allows for a range of molecular weights: smaller fractions can penetrate the stratum corneum for deeper hydration, while larger fractions reinforce the epidermal barrier and improve its intrinsic water-holding capacity. Additionally, its surfactant properties reduce the surface tension of cosmetic formulations, enabling even distribution and effective, gentle cleansing.
