Suzhou Polyethylene Glycol 4000 Supply, Common Additive in Pharmaceutical and Cosmetic Industries
Polyethylene Glycol 4000 (PEG-4000) is a white waxy solid with good water solubility, stable chemical properties, and low toxicity. Its high molecular weight characteristics make it widely used in pharmaceuticals, daily chemicals, and industrial fields, serving as a drug carrier, sustained-release agent, emulsifier, lubricant, or thickener. PEG-4000 is safe, environmentally friendly, and biodegradable, suitable for product formulations requiring high purity and stability. It is an important excipient in pharmaceuticals, cosmetics, and polymer materials.

Application Fields
Food Industry | Commonly used as an emulsifier, thickener, and humectant to improve taste and texture, extending the freshness of baked goods and condiments. Used as a defoamer in beverages to address foam issues in beer and soft drink production. |
Pharmaceutical Manufacturing | Used as a solvent, diluent, and drug carrier in the preparation of pharmaceuticals and medical supplies. |
Daily Chemical Industry | Used as a wetting agent and consistency regulator, suitable for lotions, creams, toothpaste, and hair care products. |
Industrial Manufacturing | Used in lubricants, coatings, paints, pulp, and textiles, providing auxiliary, diluent, and surface treatment functions. Serves as a coolant and antifreeze, lowering the freezing point of liquids to ensure equipment operates normally at low temperatures. |
Packaging Method
Kraft Paper Bag
Stability and Storage Conditions
Storage Conditions: Polyethylene glycol is hygroscopic and should be stored in a sealed container (glass, plastic, aluminum, or stainless steel) in a cool, dry place, away from direct sunlight.
