It has excellent lubricity, moisturizing, dispersion and adhesion. It can be used as antistatic agent and softener in cosmetics, pharmaceuticals, chemical fibers, rubber, plastics, papermaking, paints, electroplating, pesticides, metal processing and food. It has a wide range of applications in processing and other industries.

Product introduction
Polyethylene glycol (PEG), also known as polyethylene oxide or Polyoxyethylene, is a versatile polymer composed of repeating glycol diether units. Its molecular formula is H O(CH₂CH₂O)ₙH, where n represents the degree of polymerization. With a molecular weight ranging from several hundred to several million, PEG is widely used across pharmaceutical, cosmetic, industrial, and electronic applications due to its excellent emollient, hygroscopic, and softening properties.
Our pharmaceutical-grade Polyethylene glycol meets current EP and USP standards, ensuring high purity, consistency, and safety for your advanced formulations.
Key Features & Benefits
