Stearalkonium chloride is a type of benzalkonium chloride which is used as an anti-static agent, a surfactant and an antimicrobial.^[1] It is an ingredient in some cosmetics and hair care products, particularly conditioners.^[2] It was originally designed by the fabric industry for use as a fabric softener.

Toxicology studies have determined that stearalkonium chloride is safe and non-toxic at the concentrations typically used in cosmetic products (0.1 to 5%).^[3] At higher concentrations (25% solution), it has been shown to cause minor skin and eye irritation in animals.^[3]
