DIALLYLDIMETHYL AMMONIUM CHLORIDE.

Valuable CAS 7398-69-8 / NOT REPORTED

Diallyldimethyl Ammonium Chloride (DADMAC) is primarily utilized as a monomer to create cationic polymers like Polyquaternium-6. These polymers impart conditioning properties, providing a smooth, velvety feel and helping reduce skin tightness after drying.

Summary

Monomer for conditioning agents Antistatic agent (as polymer) Film former (as polymer) Skin conditioning agent (as polymer)

Science

Mechanism of Action

When polymerized, DADMAC forms highly charged cationic substances that effectively neutralize negative charges on the skin surface. This interaction leads to beneficial conditioning, antistatic, and film-forming effects, contributing to improved skin moisturization and texture.
