Application Notes
|
|
Food Industry
|
It is used for emulsification, thickening, anti-crystallization, stabilization, and moisturizing, improving the viscosity and texture of food. In baking, it prevents ice crystals and extends freshness; in sauces, seasonings, and gravy, it acts as a thickener and preservative, making the texture smoother and inhibiting microbial growth.
|
|
Beverage industry
|
As an antifoaming agent, it reduces foaming problems in beer and soft drink production and improves production stability.
|
|
manufacturing
|
Used as a coolant and antifreeze, it lowers the freezing point of liquids and is suitable for automobiles, industrial equipment, and air conditioning systems, ensuring normal operation in low-temperature environments.
|
|
Pharmaceutical manufacturing
|
As a solvent, diluent, and carrier for drug delivery systems, it can be used in the preparation of drugs and medical products.
|
|
Daily chemical industry
|
It is used as a wetting agent and consistency regulator, and is often used in products such as creams, lotions, toothpaste, shaving creams, and detergents. It is also suitable for non-rinsing hair care products, giving hair a silky shine.
|
|
Industrial manufacturing
|
It is used as a wetting agent and consistency regulator in creams, lotions, toothpaste, shaving creams, and cleaning products. When used in leave-in hair care products, it can increase the shine of hair.

Packaging
tonnes, leather drums, tank trucks, and kraft paper bags
Stability and storage conditions
Polyethylene glycol (PEG) is hygroscopic and should be stored in tightly closed containers, such as glass, plastic, aluminum, and stainless steel containers, in a cool, dry place, avoiding direct sunlight. PEG is a flammable liquid; therefore, fire safety regulations must be followed during storage and handling. Keep away from open flames, heat sources, and oxidizers.
