Storage: Propylene glycol should be kept in a tightly closed container. Additional information: Propylene glycol is hygroscopic. Boiling range, 185-189 ?C. Identity test: Dissolve 0.1 mL in sufficient water to produce 100 mL, dilute 1 mL to 10 mL, and place 0.5 mL of this solution in a test-tube. Cool in ice, add 5 mL of a cooled mixture of 10 mL of water and 90 mL of sulfuric acid (~1760 g/l) TS, heat on a water-bath at 70 ?C for10 minutes, and cool again. Add 0.2 mL of triketohydrindene/sodium metabisulfite TS; a violet colour slowly appears.",
