DODECYLHEXADECYLTRIMONIUM CHLORIDE

Description

Dodecylhexadecyltrimonium chloride is a quaternary ammonium compound widely used in personal care and cosmetic products. This cationic surfactant functions primarily as a conditioning agent and antistatic additive in hair and skin formulations. Its molecular structure consists of a positively charged nitrogen atom bonded to three alkyl groups and a chloride counterion.

In haircare applications, dodecylhexadecyltrimonium chloride effectively reduces static electricity, improves combability, and enhances the overall manageability of hair. It forms a thin, protective film on the hair shaft, which helps to smooth the cuticle and increase shine. In skincare formulations, it acts as an emulsifier and helps to stabilize oil-in-water emulsions.

The ingredient demonstrates antimicrobial properties, making it useful as a preservative enhancer in some formulations. It is typically used in concentrations ranging from 0.1% to 5%, depending on the specific product application. While generally considered safe for use in cosmetics, some individuals may experience skin irritation at higher concentrations. As with many quaternary ammonium compounds, dodecylhexadecyltrimonium chloride is biodegradable but may exhibit aquatic toxicity, necessitating careful consideration in product development and disposal practices.
