Product Usage

Polyethylene Glycol (PEG for short), with the chemical formula HO-(CH₂CH₂O)ₙ-H, is a water-soluble polymer. Its appearance varies from colorless transparent liquid to white solid depending on the molecular weight, with good water solubility, biocompatibility, chemical stability, non-toxicity and odorlessness. Its core applications are extensive. In the medical field, it is used as a drug carrier, cosolvent and ointment base, which can improve drug solubility, extend drug efficacy, and is also used in sustained-release preparations and targeted drug delivery systems. In the food industry, as a food additive, it is used as a thickener, emulsifier and humectant to improve food taste and stability. In addition, it is used in the cosmetics field to moisturize, lock water and soften the skin; in the industrial field, it is used as a lubricant and dispersant for coatings, plastic modification, etc., and is a versatile functional polymer material in multiple fields.
