Benzethonium chloride is a quaternary amine antimicrobial that can also be used as a personal care preservative. Benzethonium chloride exhibits a broad spectrum of microbiocidal activity against bacteria, fungi, mold and viruses.
It has been shown to increase moisture levels in the skin with repeated use. Its quaternary nitrogen is attracted to the skin and hair and contributes to a soft, powdery after-feel.
The suggested usage levels are 0.5% for skin applications, and 0.02% for eye area products. It can be added at room and elevated temperatures in any phase of production and is soluble in water, lower alcohols and glycols.
It is compatible with a wide variety of formulations, and effective over a wide pH range.
