Description
Propylene Glycol USP 99.8%
Propylene Glycol USP 99.8% (CAS 57-55-6, molecular formula C3H8O2) is a workhorse solvent across coatings, cleaning and process manufacture, valued for its predictable evaporation behaviour and consistent purity from batch to batch. China Chemicals supplies it at 99.8% min in pack sizes from 1 L through to 200 L Drum, so laboratory trial quantities and full production volumes can be sourced from the same specification.
It is also traded as MPG, 1,2-Propanediol, Propane-1,2-diol. Every consignment ships with a batch-specific Certificate of Analysis and the current Safety Data Sheet, and material is stored and picked under stock rotation so you receive product well inside its shelf life.
Typical applications
- Food, flavour and fragrance carrier at USP grade
- Low-toxicity heat transfer and food-plant coolant
- Humectant and solvent in personal care formulation
- Unsaturated polyester resin production
- De-icing and aircraft anti-icing fluids
