LAURALKONIUM BROMIDE

Description

Lauralkonium bromide is a quaternary ammonium compound widely used in skincare and personal care products for its antimicrobial and preservative properties. This synthetic ingredient belongs to the family of cationic surfactants, known for their ability to disrupt microbial cell membranes. Its chemical structure consists of a long alkyl chain attached to a positively charged nitrogen atom, making it effective against a broad spectrum of bacteria, fungi, and certain viruses.

In skincare formulations, lauralkonium bromide typically serves as a preservative, extending product shelf life by inhibiting microbial growth. It is particularly useful in leave-on products and those with high water content, where microbial contamination risks are higher. The ingredient's surfactant properties also contribute to its cleansing and emulsifying capabilities, aiding in the removal of dirt and oil from the skin.

While effective, lauralkonium bromide is used in low concentrations due to potential irritation at higher levels. Its use is regulated in cosmetics, with concentration limits set by governing bodies to ensure safety. Formulators must balance its preservative efficacy with potential sensitization risks, especially in products intended for sensitive skin or prolonged use.
