Description

Steareth-10 is a non-ionic surfactant belonging to the polyoxyethylene alkyl ether family, synthesized from stearyl alcohol and ethylene oxide. This versatile compound is valued for its excellent emulsifying, solubilizing, and stabilizing properties in a wide range of formulations. It is a critical ingredient for manufacturers in the personal care, pharmaceutical, and industrial sectors seeking reliable performance and ingredient compatibility.

Application

• Cosmetics & Personal Care: Acts as a primary or co-emulsifier in creams, lotions, and ointments for stable oil-in-water emulsions.
• Pharmaceuticals: Used as an emulsifying agent in topical drug delivery systems and as a solubilizer for poorly soluble active ingredients.
• Household & Industrial Cleaners: Functions as a surfactant and detergent in liquid soaps, hard surface cleaners, and textile processing aids.
• Agrochemicals: Employed as an emulsifier and dispersant in pesticide and herbicide formulations to enhance sprayability and efficacy.
• Chemical Intermediates: Serves as a raw material for the synthesis of more complex specialty surfactants and esters.
