Benzyl alcohol is a very useful fixative. It is an essential spice for mixing jasmine, moonlight and Iran. It is used for making soap and daily cosmetic essence. However, benzyl alcohol can oxidize slowly and naturally, and some of them can form benzaldehyde and benzyl ether, which makes the products on the market often have almond flavor, so it is not suitable for long storage. Benzyl alcohol is widely used in the production of industrial chemicals, such as coating solvent, photographic developer, PVC stabilizer, synthetic resin solvent, vitamin B injection solvent, ointment or liquid preservative. It can also be used as desiccant for nylon fiber and plastic film.
