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 across personal care, textile, and industrial cleaning applications.

Its strong affinity for negatively charged surfaces drives its use as a conditioning agent, softener, and antistatic treatment. In fabric softeners and rinse conditioners, DSDMAC deposits onto fiber surfaces to reduce static charge.

This action improves tactile softness, making it a primary active in both consumer and institutional laundry formulations. Hair conditioners and detangling treatments rely on it to coat damaged, negatively charged hair strands.

This process improves combability and reduces flyaway. Textile and leather processors use it as a fiber lubricant and softening agent during finishing operations, where uniform surface deposition is critical to end-product quality.

In paper manufacturing, it functions as a surface modifier to improve softness and reduce interfiber friction in tissue and specialty paper grades. The compound is supplied as a paste, flake, or aqueous dispersion.

Active content typically ranges from 50% to 90% depending on grade. Both technical and cosmetic grades are available, with cosmetic-grade material meeting purity requirements for personal care formulations.

Buyers should confirm active content, solvent carrier, and viscosity profile when sourcing for specific process or formulation requirements. This ensures the material meets the necessary performance standards for the application.
