Propylene Glycol (MPG)

Formula: C₃H₈O₂ GOST/CAS: ГОСТ/CAS: 57-55-6

Propylene glycol (monopropylene glycol) is a colorless, viscous, odorless liquid with a slightly sweet taste. Due to its hygroscopicity, low toxicity, and ability to dissolve both organic and inorganic substances, it is an essential component in various industries. It possesses unique antifreeze properties, making it a safe alternative to ethylene glycol in heating and cooling systems.

Applications

Food Industry: Used as a humectant and a solvent for flavorings and extracts (food additive E1520).
Cosmetics and Personal Care: Included in creams, shampoos, and toothpastes as a softener, moisturizer, and emulsifier.
Heating and Cooling Systems: Applied as a heat transfer fluid (antifreeze) in residential buildings and food processing facilities.
Pharmaceuticals: Used as a solvent for medications, vitamins, and ointments.

Key Advantages

Low Toxicity: Safe for humans and the environment, allowing its use in the production of consumer goods.
Bactericidal Properties: Helps prevent the growth of microorganisms in cosmetic formulations and antiseptics.
High Hygroscopicity: Effectively retains moisture, preventing food products and cosmetics from drying out.
Temperature Stability: Provides protection against freezing in systems at extremely low temperatures without damaging equipment.

Storage & Transportation

  • Store in original, tightly closed containers in a dry, cool, and well-ventilated warehouse.
  • Protect from direct sunlight and contact with strong oxidizing agents.
  • Transportation is permitted by all types of covered vehicles in accordance with cargo regulations, ensuring protection from moisture and mechanical damage.
