Storage:
This product is slowly oxidized into benzaldehyde and benzoic acid in the air and does not react with water. The aqueous solution can be sterilized by filtration or autoclaving, but benzaldehyde may be produced during autoclaving.
It should be stored in metal or glass sealed containers, not plastic containers (except polypropylene containers or Teflon coated containers) and preserve in a cool, dry and dark place.
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.
