Description

Steareth-5 Stearate is a non-ionic surfactant and emulsifier belonging to the class of polyoxyethylene fatty acid esters. This versatile compound is valued for its ability to stabilize oil-in-water emulsions and modify the texture and consistency of formulations. It is a critical ingredient for manufacturers in the personal care, cosmetics, and pharmaceutical industries seeking reliable performance in creams, lotions, and ointments.

Application

• Primary Emulsifier in oil-in-water (O/W) creams and lotions for skincare and cosmetics.
• Co-emulsifier and Stabilizer in pharmaceutical ointments and topical drug delivery systems.
• Texture Modifier to provide a rich, smooth, and non-greasy feel in personal care formulations.
• Viscosity Enhancer in liquid soaps, shampoos, and conditioners.
• Base Ingredient in the production of make-up products like foundations and liquid compacts.
• Industrial Applications as an emulsifier and dispersant in specialty chemical and agrochemical formulations.
