DECETH-7.

Valuable CAS - / SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

A high-performance non-ionic surfactant and ethoxylated fatty alcohol used to stabilize complex cosmetic structures. It functions as a sophisticated mediator between oil and water, ensuring formulations remain homogeneous and effectively lift debris from the skin's surface.

Emulsifying Surfactant Cleansing Agent Dispersant

Science

By reducing the surface tension of water, Deceth-7 facilitates the emulsification of immiscible liquids and improves the wetting properties of a product. Its hydrophilic molecular structure allows it to bind to oil-based impurities and soil, enabling them to be efficiently dispersed and rinsed away without disrupting the skin's barrier integrity.
