Description

Steareth-2 is a non-ionic surfactant belonging to the polyoxyethylene alkyl ether family, synthesized from stearyl alcohol and ethylene oxide. This versatile emulsifier and solubilizer is valued for its ability to stabilize oil-in-water emulsions and enhance the compatibility of ingredients in complex formulations. It is a critical component for manufacturers in the personal care, cosmetic, and pharmaceutical industries seeking reliable performance and mildness.

Application

• Primary emulsifier and co-emulsifier in creams, lotions, and ointments for personal care and topical pharmaceuticals.
• Solubilizer for fragrances, essential oils, and active ingredients in clear gels and aqueous solutions.
• Key ingredient in hair care formulations such as conditioners and styling products to provide lubrication and softness.
• Used in makeup products, including foundations and liquid lipsticks, for smooth texture and even application.
• Component in industrial applications as a wetting agent, dispersant, or intermediate for further ethoxylation.
