Benzalkonium Chloride

Overview

Benzalkonium chloride is a cationic surfactant, which means it holds a positive chemical charge and contains a water-loving portion and an oil-loving portion.

Cationic surfactants are commonly used in hair care to condition and soften the hair, but benzalkonium chloride has another trait that makes it useful elsewhere. As an antimicrobial ingredient, benzalkonium chloride is used for broad spectrum preservation of skincare products, including cleansing products, lotions, and serums.

Broad spectrum protection means this ingredient can protect against microbes such as bacteria, yeast, and fungi.
