Product Details
Sodium Oleate (CAS#143-19-1) is a highly effective anionic surfactant derived from oleic acid and sodium hydroxide. Featuring both hydrophilic and hydrophobic groups, it offers outstanding emulsifying performance, enabling the formation of stable oil–water systems in a wide range of formulations. The product also demonstrates excellent penetrating, wetting, and detergency properties, making it widely used in soaps, detergents, textile auxiliaries, and industrial cleaning applications. In addition, Sodium Oleate exhibits good solubility in hot water, which improves processing efficiency and formulation compatibility.
