Sodium Octadecyl Sulfate
Sodium octadecyl sulfate (CAS 2432-87-3) is a long-chain anionic surfactant with formula C₁₈H₃₇NaO₄S and MW 372.54, based on an octadecyl (C18) chain and a sulfate group. It is used as an emulsifier, wetting agent and dispersant in personal-care, textile and industrial formulations.
• Emulsifier for cosmetics and creams: stabilizes oil-in-water emulsions and improves texture.
• Textile processing: wetting and leveling agent in dyeing and finishing baths.
• Industrial cleaners and emulsifiers: emulsion polymerization and dispersant for pigments and fillers.
• Long-chain anionic surfactant: where a C18 hydrophobe is advantageous.
