BENZETHONIUM CHLORIDE
Commonly Found In
Overview
Benzethonium chloride is a synthetic quaternary ammonium compound used as an antimicrobial preservative and antiseptic in cosmetics. The EU permits it at up to 0.1% in non-mucous membrane products and 0.05% in mucous membrane products. In 2016, the US FDA removed it from OTC antiseptic hand soap formulations due to insufficient data on safety and efficacy.
Also known as: phemerol chloride, hyamine 1622, BZT
Key Benefits
Provides antimicrobial and preservative action against a broad spectrum of bacteria and some fungi. Studies suggest no superiority over conventional soap and water for hand hygiene, which contributed to FDA OTC removal.
