Description

Bis(Dodecyltrimethylammonium) Sulfate is a high-purity quaternary ammonium compound (quat) salt, valued for its potent surfactant and antimicrobial properties. This dialkyl quaternary ammonium sulfate is a critical raw material for formulating high-performance biocides, disinfectants, and fabric softeners. It is essential for manufacturers in the industrial biocide, personal care, textile treatment, and water treatment sectors seeking reliable, effective cationic surfactants.

Application

• Primary active ingredient in industrial and institutional disinfectants and sanitizers.
• Key component in fabric softeners and textile conditioners for superior antistatic and softening effects.
• Emulsifier and phase transfer catalyst in specialty chemical synthesis.
• Biocide and algicide in industrial water treatment and cooling tower systems.
• Antimicrobial agent in personal care products such as hair conditioners.
• Additive in paper manufacturing for retention and drainage aids.
• Surface modifier and antistatic agent for plastics and polymers.
• Research and development chemical for novel surfactant formulations.
