Polyethylene Glycol (PEG) is a water-soluble polymer available in various molecular weights, ranging from low-viscosity liquids to waxy solids. Known for its versatility, biocompatibility, and non-toxicity, PEG is widely used in pharmaceutical, cosmetic, personal care, food, and industrial applications. It serves as a solvent, plasticizer, dispersing agent, humectant, and base material in numerous formulations. PEG’s high purity, stability, and compatibility with various substances make it a preferred choice in multiple industries.
