Propylene Glycol(PG) CAS 57-55-6
Propylene Glycol (PG), chemically known as propane-1,2-diol, is a high-purity, colorless, and viscous liquid with a faint, characteristic odor. It is completely miscible with water and various organic solvents. As a leading certified Propylene Glycol & PG manufacturer, we provide high-performance Industrial/Tech grade PG that meets stringent global production standards.
Our Propylene Glycol is characterized by its high chemical stability and low toxicity, making it an essential raw material in modern chemical synthesis. It serves as a versatile solvent, humectant, and intermediate in a wide range of industrial processes.
- Superior Solvency: Effectively dissolves both natural and synthetic substances, making it ideal for complex formulations in flavors, fragrances, and active ingredients.
- Hygroscopic & Humectant Properties: Naturally attracts and retains moisture, which is crucial in preventing products from drying out, particularly in cosmetics and food-related applications.
- Low Toxicity Profile: With extremely low vapor pressure and irritation levels, it is safe for use in diverse industrial and pharmaceutical environments.
- Excellent Thermal Stability: Remains stable and resistant to degradation under varied storage and processing conditions, ensuring a long shelf life.
- High Miscibility: Completely miscible with water, ethanol, and various organic solvents, allowing for seamless integration into liquid systems.

Appearance: Industrial Grade PG is colorless viscous stable water-absorbing liquid, almost tasteless, odorless, flammable, low toxicity.
Water Solubility: It can be miscible with water, ethanol, ether, chloroform, acetone and other organic solvents. Although the solubility to hydrocarbons, chlorinated hydrocarbons, fats is small, but the solubility of ethylene glycol is stronger.
Properties: It is 99.7% pure, colorless, viscous, stable, water-absorbing liquid, almost tasteless and odorless. Miscible with water, ethanol and various organic solvents.
Package: Available in 215kg iron drums, 200kg plastic drums, or 25kg small drums to suit different production scales.
Storage: This product should be sealed and stored in a cool, dry, and well-ventilated area. Keep away from fire, high temperature, and direct sunlight.
Safety Protection: The toxicity and irritation are very low. When added to food and beverages, if the dosage is too high at one time, there is a risk of causing fatal sleepiness and kidney disorders. Although this product will not spontaneously combust, it is a flammable material.
Fire Protection: Fire extinguishing agent: mist water, foam, carbon dioxide, dry powder, sand.
About Us: With over many years as a certified Propylene Glycol & PG manufacturer, we combine innovation with stringent production standards to deliver high-performance product.
