CETRIMONIUM BROMIDE

Description

Cetrimonium bromide is a quaternary ammonium compound widely used in skincare and haircare formulations. This cationic surfactant serves multiple functions, primarily as an antimicrobial agent and conditioning ingredient. Its molecular structure consists of a positively charged nitrogen atom bonded to three methyl groups and a long alkyl chain, providing both water-soluble and oil-soluble properties.

In skincare, cetrimonium bromide acts as a preservative, helping to prevent microbial growth in products. It also functions as an emulsifier, aiding in the stable combination of oil and water-based ingredients. The compound's positive charge allows it to adhere to negatively charged skin and hair surfaces, imparting softness and reducing static electricity.

Cetrimonium bromide is particularly effective in haircare formulations, where it improves manageability, reduces frizz, and enhances shine. Its antistatic properties make it valuable in leave-in conditioners and styling products. While generally considered safe for use in cosmetics at regulated concentrations, some individuals may experience skin irritation or allergic reactions. As with any active ingredient, patch testing is recommended before widespread use, especially for those with sensitive skin or known allergies to quaternary ammonium compounds.
