Application Notes

Food Industry

Polyethylene glycol 600 is commonly used as an emulsifier, thickener, anti-crystallization agent, stabilizer, and humectant. It can improve the viscosity and stability of food, and enhance its taste, texture, and appearance. In baked goods, it prevents ice crystal formation and extends freshness; in sauces, condiments, and gravy, it acts as a thickener and preservative, giving products a smooth, creamy texture while inhibiting the growth of bacteria and fungi.

Beverage industry

It can be used as an antifoaming agent in the production process of beer and soft drinks to effectively solve the problem of excessive foam and ensure the stability of product appearance and quality.

manufacturing

Polyethylene glycol 600 can be used as a coolant, antifreeze, additive, diluent, or surface treatment agent to lower the freezing point of liquids and prevent icing in cooling systems. It is commonly used in the automotive, industrial equipment, air conditioning systems, lubricating oil, coatings, paints, pulp, and textile industries to ensure normal liquid flow in low-temperature environments and improve product processing performance.

Pharmaceutical manufacturing

It can be used as a solvent, diluent, and carrier for drug delivery systems in the preparation of various pharmaceuticals and medical products.

Daily chemical industry

It is used as a wetting agent and consistency regulator, and is widely used in products such as creams, lotions, toothpaste, shaving cream and detergents; it is also suitable for leave-in hair care products, giving hair smoothness and shine.

Coatings industry

Polyethylene glycol 600 has wide applications in the coatings industry. It can participate in the curing of epoxy resins, improve the flexibility, impact strength, and adhesion of coatings, and reduce shrinkage. At the same time, it can disperse pigment particles, adjust the viscosity of the system, optimize the leveling and gloss of coatings, and enhance the freeze resistance of coatings, ensuring the performance of construction and use in low-temperature environments.
