product description
Chemical Identity: Polyethylene glycol (PEG, CAS#25322-68-3) is a polyether commonly represented as H–[O–CH₂–CH₂]ₙ–OH. Grades such as PEG 200, PEG 400, PEG 1000, PEG 4000, and PEG 6000 refer to nominal average molecular weights.
Grade-Dependent Physical Forms: Lower molecular weight grades are typically clear, viscous liquids, while higher molecular weight grades are generally white, waxy solids, flakes, or powders. Physical form and melting range depend on the grade.
Water Solubility and Formulation Properties: PEG is generally soluble in water. Solution viscosity and dissolution behavior vary with molecular weight, concentration, and temperature. Depending on the grade, it is used as a solvent, humectant, binder, or plasticizer.
Applications and Quality Specifications: PEG is used in polymer processing, chemical formulations, and suitable grades of personal care and pharmaceutical manufacturing. Quality parameters may include average molecular weight, hydroxyl value, water content, and relevant impurity limits, as specified in the product documentation.
