Features Of Polyethylene Glycol PEG1500

  1. Highly water-soluble polymer with excellent hygroscopicity and low volatility.

  2. Non-toxic, non-irritating, and compliant with major pharmacopeial standards (USP/EP).

  3. Optimal balance of viscosity and molecular weight for formulation flexibility in liquid and semi-solid systems.

  4. Chemically stable under neutral to mildly acidic conditions; resistant to oxidation and hydrolysis.

  5. Readily biodegradable and environmentally compatible compared to higher-MW PEGs.

Typical Applications Of Polyethylene Glycol PEG1500

  1. Pharmaceutical excipient in oral liquids, ointments, and suppository bases.

  2. Humectant and solubilizer in cosmetic formulations including creams, gels, and cleansing agents.

  3. Processing aid and binder in solid dosage form manufacturing (e.g., wet granulation).

  4. Component in industrial lubricants and metalworking fluid additives for film-forming and corrosion inhibition.

  5. Stabilizer and dispersant in agrochemical suspensions and encapsulated pesticide delivery systems.
