C12-14 SEC-PARETH-50.

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

A highly ethoxylated non-ionic surfactant that excels at creating stable oil-in-water emulsions and solubilizing challenging ingredients like oils and fragrances. With 50 moles of ethylene oxide in its structure, this ingredient provides exceptional hydrophilic properties for complex formulation stability.
