Overview
Benzyl Alcohol is used as an anti-parasite medication used to treat head lice and as a common preservative in many injectable drugs. It is a colourless liquid that occurs naturally in plants and fruits is entirely miscible with alcohol and diethyl ether. It is an ideal general solvent due to its polarity and low vapor pressure.
