Distearyldimethylammonium chloride

Distearyldimethylammonium chloride (CAS 107-64-2), also known as DSDMAC or Varisoft 100, is a quaternary ammonium compound used as a cationic surfactant.

Where is Distearyldimethylammonium chloride used?

• Personal care: conditioning agent, softener and antistatic treatment
• Laundry: primary active in fabric softeners and rinse conditioners, depositing onto fiber surfaces to reduce static charge
• Hair care: coating damaged, negatively charged strands to improve combability and reduce flyaway
• Textile and leather finishing: fiber lubricant and softening agent
• Paper manufacturing: surface modifier that improves softness and reduces interfiber friction in tissue and specialty grades
• Its strong affinity for negatively charged surfaces drives these uses.

Good to know: Cosmetic-grade material meets purity requirements for personal care formulations.

Commercial specifications

• Active content typically 50% to 90% depending on grade
• Buyers should confirm active content, solvent carrier and viscosity profile.
