cetrimide

Cetrimide, or alkyltrimethylammonium bromide, is an antiseptic which is a mixture of three quaternary ammonium compounds: tetradonium bromide, cetrimonium bromide (CTAB), and laurtrimonium bromide. It was first discovered and developed by ICI and introduced under the brand name Cetavlon. It is used as a 1-3 % solution for cleaning roadside accident wounds. ICI also introduced Savlon, which was a combination of cetrimide and chlorhexidine. ICI sold the Savlon brand OTC to Johnson & Johnson in May 1992. Cetrimide is used in various applications such as antiseptic agents, diagnostic test and analysis, topical formulations, and dental treatment. — Wikipedia
