Description

Isooctadecyltrimethylammonium Chloride is a high-purity quaternary ammonium compound (quat) valued for its cationic surfactant properties. This chemical is essential for providing antistatic, emulsifying, and conditioning effects in a wide range of industrial formulations. It is particularly sought after by manufacturers in the personal care, textile, and specialty chemical sectors seeking reliable performance and consistent quality.

Application

• Hair Conditioners & Cream Rinses: Acts as a primary cationic surfactant, providing excellent detangling, softness, and manageability to hair.
• Fabric Softeners & Antistatic Agents: Imparts a soft hand-feel and reduces static cling in textile finishing and laundry care products.
• Industrial Biocides & Sanitizers: Serves as an active ingredient in formulations for disinfecting hard surfaces and controlling microbial growth in water treatment and industrial processes.
• Emulsion Stabilizer: Functions as an effective cationic emulsifier for oil-in-water systems in cosmetic and industrial applications.
• Asphalt & Road Treatment Additives: Used as an adhesion promoter and antistripping agent to improve the bonding between asphalt and aggregates.
• Paper & Pulp Chemicals: Employed as a retention aid, drainage aid, or softener in paper manufacturing processes.
• Mineral Flotation: Acts as a collector or frothing agent in the beneficiation of certain ores.
• Research & Development: Utilized as a standard or intermediate in chemical synthesis and material science research.
