Polyoxypropylene stearyl ether（Cat No.:R000069）is a nonionic surfactant formed by the ethoxylation and propoxylation of stearyl alcohol. It features a long hydrophobic stearyl (C18) chain and a polyoxypropylene backbone, offering emulsifying, dispersing, and solubilizing properties. Commonly used in cosmetics, personal care products, and industrial formulations, it enhances the texture, stability, and spreadability of creams, lotions, and emulsions. Its amphiphilic nature allows it to function effectively in oil-in-water and water-in-oil systems. Polyoxypropylene stearyl ether is valued for its mildness, compatibility with other surfactants, and thermal stability.
