Polyethylene glycol 400

Polyethylene glycol 400 has wide applications in the coatings industry. With its excellent water solubility and compatibility, it can be used as a pigment dispersant, effectively preventing pigment aggregation and improving the stability of the coating system. It can also adjust coating viscosity and optimize application leveling. Furthermore, it can participate in the resin curing reaction, enhancing coating flexibility and adhesion, and improving the coating's low-temperature freeze resistance, ensuring high-quality application even at low temperatures.

Application areas

Application areas	Application Notes
Food Industry	Polyethylene glycol 400 is commonly used as an emulsifier, thickener, anti-crystallization agent, stabilizer, and humectant. It can improve the viscosity and structural stability of food systems, and enhance their taste, texture, and appearance. In baked goods, it helps prevent ice crystal formation and extend shelf life; in sauces, condiments, and gravy, it can enhance rheological properties and inhibit microbial growth.
Beverage industry	Polyethylene glycol 400 can be used as an antifoaming agent to effectively control foam generation during beer and soft drink production, thereby improving production efficiency and product uniformity.
manufacturing	As a coolant and antifreeze, it can lower the freezing point of liquids and prevent the cooling system from freezing. It is widely used in automobiles, industrial equipment and air conditioning systems to ensure the fluidity of liquids and the stability of systems under low temperature conditions.It can be used as an additive, diluent, or surface treatment agent in fields such as lubricating oil, coatings, paints, pulp, and textiles .
Pharmaceutical manufacturing	It can be used as a solvent, diluent, and delivery carrier for the dissolution, dispersion, and stabilization of active ingredients in formulation development and medical product manufacturing .
Daily chemical industry	As a wetting agent and viscosity modifier, it is used in creams, lotions, toothpaste, shaving cream and cleaning products. It can also be used in leave-in hair care products to improve product flow and give hair a silky shine.

Packaging

tonnes, leather drums, tank trucks, and kraft paper bags

Stability and storage conditions

Store in a tightly closed container, such as glass, plastic, aluminum, or stainless steel, in a cool, dry place, avoiding direct sunlight. Polyethylene glycol is a flammable liquid; therefore, fire safety regulations should be followed during storage and handling. Keep away from open flames, heat sources, and oxidizers.
