Features Of Dow PEG4000 Polyethylene Glycol

  1. Highly purified, low-volatility polyethylene glycol with narrow molecular weight distribution (Mn ≈ 4000 Da).

  2. Excellent water solubility and hygroscopicity, enabling efficient formulation in aqueous systems.

  3. Non-toxic, non-irritating, and compliant with major pharmacopeial standards (USP/EP/JP) for pharmaceutical use.

  4. Thermally stable up to 150 °C under inert conditions, supporting processing in melt-based applications.

  5. Low residual ethylene oxide and aldehyde content, ensuring enhanced safety and regulatory acceptance.

Typical Applications Of Dow PEG4000 Polyethylene Glycol

  1. Pharmaceutical tablet binder and controlled-release matrix excipient.

  2. Vehicle and solubilizer in topical and ophthalmic formulations.

  3. Plasticizer and processing aid in polymer films and coatings.

  4. Humectant and viscosity modifier in personal care products such as toothpaste and moisturizers.

  5. Carrier and dispersant in agrochemical suspension concentrates (SC) and seed treatment formulations.
