BENZETHONIUM CHLORIDE
Description
Benzethonium chloride is a synthetic quaternary ammonium compound widely used in skincare and personal care products for its antimicrobial and preservative properties. This cationic surfactant effectively combats both gram-positive and gram-negative bacteria, as well as some fungi and viruses, making it a versatile ingredient in various formulations.
In skincare, benzethonium chloride is primarily employed as a preservative, extending the shelf life of products by preventing microbial growth. Its efficacy is particularly notable in leave-on formulations such as lotions, creams, and gels. The compound also functions as an antiseptic, contributing to the cleansing properties of certain skincare products.
Typically used in concentrations ranging from 0.01% to 0.2%, benzethonium chloride is generally well-tolerated by most skin types. However, like many preservatives, it may cause irritation in sensitive individuals. Its antimicrobial action works by disrupting cell membranes of microorganisms, leading to their destruction.
While effective, benzethonium chloride is subject to regulatory limitations in various countries due to potential environmental concerns. Formulators must consider these regulations and potential alternatives when developing products for international markets.
