Products Description

What is Propylene Glycol?

Propylene Glycol, also known as 1,2-Propanediol, is a colorless, tasteless, almost odorless viscous liquid with good hygroscopicity and low toxicity. Its molecular formula is C₃H₈O₂, its relative molecular mass is 76.09, its boiling point is about 188.2°C, its melting point is −59°C, and its density is 1.036 g/cm³ (20°C). It is miscible with water, ethanol and a variety of organic solvents, and has strong polarity and good solubility. PG has low vapor pressure and high thermal stability, is not easy to volatilize in the air, has stable chemical properties, and is often used in systems that need to dissolve polar or water-soluble components.

Basic Info

Uses

Propylene Glycol has many uses：

• Chemical raw materials: Propylene Glycol is an important raw material for unsaturated polyesters, epoxy resins and polyurethane resins, used in the manufacture of surface coatings and reinforced plastics. In addition, it is also used as a plasticizer for alkyd resins and a raw material for plasticizers.
• Food industry: In the food industry, PG can be used as a food additive, such as an emulsifier and a solvent. It often reacts with fatty acids to form propylene glycol fatty acid esters, which are used as food emulsifiers. In addition, it is also an excellent solvent for condiments and pigments.
• Pharmaceutical industry: It is often used as a solvent, softener and excipient for drugs, especially in the manufacture of various ointments and ointments. Due to its non-toxicity, good viscosity and hygroscopicity, it is often used in topical, oral or intravenous pharmaceutical products.
• Cosmetic industry: PG is often used in combination with glycerol or sorbitol as a wetting agent. It is also used in hair dyes as a moisturizing and leveling agent.
• Other uses: 1,2-Propanediol is also used as a tobacco humidifier, mildew inhibitor, lubricant for food processing equipment and solvent for food marking inks. It is also an effective antifreeze agent and is often used to prevent liquids from freezing.
