DODECYLBENZYLTRIMONIUM CHLORIDE

Description

Dodecylbenzyltrimonium chloride is a quaternary ammonium compound widely used in personal care and cosmetic products. This cationic surfactant serves multiple functions, including as an antimicrobial agent, preservative, and conditioning agent. Its molecular structure consists of a positively charged nitrogen atom bonded to three methyl groups and a long alkyl chain, providing both hydrophilic and hydrophobic properties.

In skincare formulations, dodecylbenzyltrimonium chloride acts as an effective preservative, inhibiting the growth of bacteria and fungi to extend product shelf life. Its antimicrobial properties also make it valuable in anti-acne products. As a conditioning agent, it helps improve the texture and feel of skin and hair products, leaving surfaces smooth and soft.

The ingredient is typically used in low concentrations, ranging from 0.1% to 0.5% in leave-on products and up to 1% in rinse-off formulations. While generally considered safe for use in cosmetics, some individuals may experience skin irritation or sensitization with prolonged exposure. As with any active ingredient, patch testing is recommended for those with sensitive skin or a history of allergic reactions to personal care products.
