Steartrimonium Chloride
Steartrimonium Chloride (CAS: 112-03-8) is a quaternary ammonium compound with a long C18 alkyl chain and a positively charged nitrogen center. Supplied as a white solid, it functions as a cationic surfactant. Its charge and hydrophobic chain help it associate with hair and fibers, providing conditioning, softening, and antistatic effects. Applications include personal-care conditioners and hair treatments, as well as industrial emulsification and fiber treatment. Commercial specifications vary, and intended use should be confirmed against the applicable technical data sheet before formulation.
• In hair conditioners, rinses, shampoos, and hair treatments, it serves as a cationic conditioning ingredient that supports softness, manageability, and easier combing.
• Its antistatic action makes it useful in hair-care products and in treatments for textile or other fibers.
• As a cationic surfactant, it is used to emulsify silicone oils and other hydrophobic materials in selected formulations.
• Industrial uses reported for this material include emulsification in asphalt or waterproof coatings, fiber finishing, and modification of organic bentonite; suitability depends on the formulation and grade.
