Oleth-10 (OV-10, CAS: 9004-98-2) is a nonionic surfactant derived from natural oleyl alcohol and prepared through precise ethoxylation. It appears as a light yellow transparent liquid. Its molecular formula is approximately C18H35O(C2H4O)nH (n≈10), with a molecular weight of about 708. With its balanced hydrophilic-lipophilic structure, this product exhibits excellent interfacial regulation ability and compatibility in a wide range of formulation systems.
In terms of physicochemical properties, OV-10 is readily soluble in water, has low foaming characteristics, and possesses good chemical stability, maintaining structural integrity in general acidic, alkaline, and high-hardness water systems. Its cloud point ranges from 65 to 80°C, and the active substance content is not less than 99%. These core parameters provide a reliable foundation for downstream formulation design. The product is hygroscopic and should be stored in sealed containers in a cool, dry place.
