COCOALKONIUM CHLORIDE.

Avoid CAS 61789-71-7 / ANTISTATIC, HAIR CONDITIONING, PRESERVATIVE

Cocoalkonium Chloride is a cationic surfactant that serves primarily as a preservative in cosmetic formulations, effectively inhibiting microbial proliferation. Beyond its preservative role, it also functions as an antistatic and hair conditioning agent, contributing to hair manageability and smoothness. However, its application in skin preparations is often associated with a high risk of irritation.

preservative antibacterial antimicrobial solubilizing emulsifying dispersing

Science

Mechanism of Action

As a cationic surfactant, Cocoalkonium Chloride possesses a positive charge, enabling it to interact with negatively charged surfaces, thereby reducing electrostatic charges and imparting conditioning benefits. Its efficacy as a preservative stems from its ability to disrupt microbial cell membranes, consequently preventing the growth of microorganisms in water-based cosmetic products. The compound also demonstrates antibacterial, antimicrobial, solubilizing, emulsifying, dispersing, anticorrosive, and wetting properties.
