Application areas
1. Food Industry
In food processing, it can be used as a multifunctional additive, playing a role in emulsification, thickening, anti-crystallization, system stabilization, and moisturizing, thereby improving the taste, texture, and appearance of food. When applied to baked goods, it helps inhibit ice crystal formation and extend shelf life; in sauces, seasonings, and gravy, it can enhance smoothness and thickness while inhibiting the growth of some microorganisms.
2. Beverage industry
It can be used as an antifoaming agent in the production of beer and various soft drinks to reduce excessive foam generated during production and bottling, and improve process stability.
3. Manufacturing and Equipment Sector
It has good low-temperature adaptability and can be used as a coolant or antifreeze medium to lower the freezing point of liquids and ensure that automobiles, industrial equipment and air conditioning systems can still maintain fluidity in cold environments.
4. Pharmaceutical manufacturing sector
It can be used as a solvent, diluent, and carrier for drug delivery systems, and is suitable for various formulation processes and medical product manufacturing, supporting the uniform dispersion and stable release of drugs.
5. Daily chemical and personal care industry
In personal care products, it can be used as a humectant and consistency modifier, commonly found in creams, lotions, toothpaste, shaving creams, and cleaning products. It is also suitable for leave-in hair care products, helping to improve the smoothness and shine of hair.
6. Industrial Applications
In lubricating oil, coatings, paints, papermaking and textile processing, it can be used as an auxiliary agent, diluent or surface treatment agent to improve processing performance and the surface quality of the final product.
Packaging Method
Kraft paper bag
Stability and Storage Conditions
It should be stored in a cool, dry place, avoiding direct sunlight as much as possible. Polyethylene glycol is a flammable substance, therefore, fire safety regulations should be followed during storage and handling, and it should be kept away from open flames.
