Description

Hexadecyltrimethylammonium Methyl Sulphate is a high-purity cationic surfactant and quaternary ammonium compound, also known as Cetrimonium Methyl Sulfate. This compound is valued for its excellent emulsifying, antistatic, and conditioning properties, making it a critical ingredient in high-performance formulations. It is essential for manufacturers in the personal care, cosmetics, and specialty chemical industries seeking reliable, high-quality raw materials for rinse-off and leave-on products.

Application

• Hair Care Formulations: Primary ingredient in conditioners, shampoos, and hair masks for its superior detangling, softening, and antistatic effects.
• Cosmetic Products: Used as an emulsifier and conditioning agent in skin creams, lotions, and other personal care products.
• Textile & Fiber Treatment: Functions as a softener and antistatic agent for synthetic fibers and fabrics.
• Industrial Surfactant: Acts as a cationic surfactant in various industrial processes, including emulsion polymerization and as a phase transfer catalyst.
• Biocide & Disinfectant Precursor: Serves as a key intermediate in the synthesis of other quaternary ammonium compounds (Quats) with antimicrobial properties.
