Main Application Areas

1. Pharmaceutical and Cosmetic Industry: 

Used as a drug carrier, ointment base, tablet lubricant, solvent, and plasticizer. In skin creams, toothpaste, shampoos, and lotions, it acts as a moisturizer and stabilizer, exhibiting no irritation, low toxicity, and good biocompatibility.

2. Chemical and Daily Chemical Industry: 

Used as a lubricant, emulsifier, dispersant, and defoamer in detergents, cosmetics, textile auxiliaries, inks, and coatings to improve flowability and product uniformity.

3. Rubber and Plastics Industry: 

Used as a plasticizer and lubricant to improve material flexibility, gloss, and antistatic properties.

4. Textile and Paper Industry: 

Used as a softener, sizing agent, and antistatic agent to improve fiber feel and printing uniformity.

5. Food and Agriculture: 

Food-grade PEG is used as a humectant, dispersant, and carrier solvent. In agriculture, it is used in pesticide formulation dispersion and sustained-release systems.

6. Electronics and Metal Processing: 

Used in electrolytes and polishing fluids for dispersion and brightening.
