C12-14 SEC-PARETH-30.

Valuable CAS 84133-50-6 / EMULSION STABILISING, SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

A non-ionic surfactant and emulsifier that excels at creating stable, silky-textured formulations by reducing surface tension between oil and water phases. With 30 ethoxylation units, it demonstrates exceptional solubilizing capabilities for challenging lipophilic ingredients like silicone polymers and fragrances in aqueous systems.

Science

Functions as a bridge between hydrophobic and hydrophilic phases through its amphiphilic structure, enabling uniform dispersion and stability. The high degree of ethoxylation creates a hydrophilic head group that effectively solubilizes oil-soluble components while maintaining mildness on skin surfaces.
