Lansurf OA10 is a nonionic surfactant produced by ethoxylating oleic acid with approximately 10 moles of ethylene oxide. It exhibits excellent emulsifying, wetting, and solubilising properties and demonstrates broad compatibility with nonionic, anionic, cationic, and amphoteric surfactants. Lansurf OA10 is commonly used in emulsions,
detergents, and formulations requiring effective wetting and dispersion.​​
