What it does
Benzethonium Chloride is a preservative: it kills bacteria and prevents them from growing in cosmetics and personal care products, thus prolonging their shelf-life.
It is considered less irritating than most other preservatives.
Benzethonium Chloride is safe when used in concentrations up to 0.05% on products applied on the skin, and in concentrations up to 0.02% on products applied on the eye area.
