Propylene glycol a colorless liquid with steady viscosity and good water absorption.
It is nearly odorless, uninflammable and minutely toxic. Its molecular mass is 76.09. Its viscosity (20oC), specific heat capacity (20oC) and latent heat of vaporization (101.3kpa) are respectively 60.5mpa.s, 2.49KJ/(kg. oC) and 711KJ/kg.
It can be mixed and solved with alcohol, water and various organic agents.
Propylene Glycol is the raw material for preparing unsaturated polyester resin, plasticizer, surface active agent, emulsifying agent and demulsifying agent. It can also be used as mould inhibitor, antiseptic for fruit, ice inhibitor and moisture preserving agent for tobacco.
