Propylene Glycol IP/ USP/ FR/ Technical Grade
Propylene glycol, also called propane-1,2-diol, is an organic compound with the chemical formula C3H8O2. It is a viscous colorless liquid which is nearly odorless but possesses a faintly sweet taste. Chemically it is classed as a diol and is miscible with a broad range of solvents, including water, acetone, and chloroform.
Types Of Propylene Glycol

The premium quality propylene glycol, that we offer to our clients is generally produced in industries by propylene oxide hydration. It is widely used as a less-toxic antifreeze, moisturizer in medicines, cosmetics, toothpaste, food, mouth wash and as a solvent for food colors and flavorings. Moreover, it is widely used to make artificial smoke in smoke machines and as a working fluid in hydraulic presses. Application in the formulation of hand sanitizers, antibacterial lotions, and saline solutions is yet another area of usage for propylene glycol.
These standards are required by the authorities responsible for consumer health and safety of materials used in health-sensitive applications, such as pharmaceuticals, foodstuffs, cosmetics and animal feed. These quality requirements are specifically described in the Pharmacopoeias while handling requirements are prescribed in governmental regulation and industry guidelines.

| Anti Freezing Agent Propylene Glycol
Propylene Glycol freezes at about −12°C (10.4°F), but when mixed with water, the mixture does not readily crystallize, and therefore the freezing point of the mixture is depressed. Specifically, a mixture of 60% Propylene Glycol and 40% water freezes at −45°C (−49°F). It is used as a de-icing fluid for windshields and aircraft. The antifreeze capabilities of Propylene Glycol have made it a component of vitrification (anticrystallization) mixtures for low-temperature preservation of biological tissues and organs.
The boiling point for Propylene Glycol increases monotonically with increasing Propylene Glycol percentage. Thus, the use of Propylene Glycol not only depresses the freezing point, but also elevates the boiling point such that the operating range for the heat transfer fluid is broadened on both ends of the temperature scale. The increase in boiling temperature is due to Propylene Glycol having a much higher boiling point and lower vapor pressure than pure water.
