Propylene glycol is used as an organic solvent and diluent in pharmaceuticals and many other industrial applications. Propylene Glycol (C3H8O2) is a propanediol that exists as a clear, colorless and hygroscopic liquid, consisting of propane where the hydrogens at positions 1 and 2 are substituted by hydroxyl groups.
Industrial propylene glycol is used as a heat transfer medium, to control viscosity, to dissolve active agents or protect against corrosion and pressure burst. It is also used as raw material for the production of unsaturated polyester resins. By emulsifying active ingredients, which otherwise would not mix, propylene glycol helps to create a stable homogeneous fluid allowing for the intended final product, such as a face cream or shampoo to perform its function.
With its unique combination of properties propylene glycol supports many uses. It serves as a solvent; Connects and stabilises insoluble fluids (emulsifier); Helps to bind and transport other substances (excipient); Holds and dissolves active ingredients equally in a medium; Attracts/holds water/moisture (hygroscopic); Reduces freezing point, increases boiling point; Chemically inert.

Proper human safety products such as splash goggles, lab coat, NIOSH approved gloves and boots should be worn while handling and applying chemicals. Splashes on the skin should be washed off with water immediately. In case of splashing into the eyes, flush them with fresh water and obtain medical attention. Should not be injected.
Hygroscopic nature should be stored in original vented containers, away from moisture contamination, heat, direct sunlight and combustibles. Opened drums must be closed immediately after withdrawal of the product. Store in a cool and dry place. Please refer label and SDS for details.
