ERUCALKONIUM CHLORIDE

Description

Erucalkonium chloride is a quaternary ammonium compound with notable antimicrobial and preservative properties. This synthetic ingredient is derived from erucic acid, a monounsaturated omega-9 fatty acid found in rapeseed and mustard seed oils. Its molecular structure consists of a long-chain alkyl group attached to a positively charged nitrogen atom, giving it both hydrophobic and hydrophilic characteristics.

In skincare and cosmetic formulations, erucalkonium chloride primarily functions as a preservative, protecting products from microbial contamination and extending their shelf life. It demonstrates efficacy against a broad spectrum of bacteria, fungi, and yeasts. Additionally, this compound exhibits conditioning properties, making it useful in hair care products to improve manageability and reduce static.

Erucalkonium chloride is typically used in concentrations ranging from 0.1% to 0.3%, depending on the specific formulation and desired effect. While generally considered safe for topical use, it may cause irritation in some individuals with sensitive skin. As with many preservatives, its use is regulated by cosmetic authorities to ensure product safety and efficacy. Formulators often choose erucalkonium chloride for its versatility and effectiveness in maintaining product integrity.
