HEL-40 is produced using natural hydrogenated castor oil as the starting material, introducing polyoxyethylene chains through an ethoxylation process. The product appears as a pale yellow paste to viscous liquid. As a versatile nonionic surfactant, it exhibits interfacial activity in aqueous systems without dissociation, thus demonstrating good tolerance to acidic, alkaline, and hard water conditions, making it suitable for a wide range of applications.
Its most prominent functional highlight is its "efficient solubilization" capability — it can uniformly and stably disperse hydrophobic components such as fragrances, essential oils, and oil-soluble active substances into aqueous systems, producing transparent and clear products. This is irreplaceable in formulations such as transparent aqueous cosmetics and makeup removers. Meanwhile, as a typical oil-in-water emulsifier, HEL-40 can form fine and stable emulsions, significantly improving the texture and skin feel comfort of the formulation.
In addition, HEL-40 exhibits good compatibility with various anionic, cationic, and amphoteric surfactants, offering high flexibility in formulation design. Its raw material is derived from natural castor oil, and after modification, it still maintains excellent skin compatibility. Under normal usage conditions, it causes no significant irritation to the skin and is classified as practically non-toxic. It is a green surfactant that combines functionality and safety.
