Features Of Polyethylene Glycol PEG1000

  1. Highly water-soluble, non-ionic polymer with excellent compatibility in aqueous and polar organic systems.

  2. Low toxicity and FDA-permitted for certain pharmaceutical and cosmetic applications.

  3. Thermally stable up to 150 °C under inert conditions, supporting diverse processing environments.

  4. Precise molecular weight distribution (Mn ≈ 950–1050 Da), ensuring consistent performance in formulation.

  5. Non-volatile, non-irritating, and odorless — ideal for sensitive end-use applications.

Typical Applications Of Polyethylene Glycol PEG1000

  1. Pharmaceutical excipient: binder, solubilizer, and viscosity modifier in oral liquids and topical gels.

  2. Personal care formulation: humectant and emollient in creams, lotions, and cleansing agents.

  3. Chemical synthesis: reaction medium and phase-transfer agent in esterification and condensation reactions.

  4. Industrial lubricant additive: improves film strength and reduces friction in metalworking fluids.

  5. Bioconjugation platform: functionalizable terminal hydroxyl groups for protein PEGylation (pre-activation required).
