What is Polyethylene Glycol?
Polyethylene Glycol (PEG) is a family of polyether compounds produced through the polymerisation of ethylene oxide, available across a wide range of molecular weights from approximately 200 g/mol up to 6000 g/mol and beyond. The physical state changes dramatically across this range — low molecular weight grades (PEG 200 to PEG 600) are clear liquids, while higher molecular weight grades (PEG 1000 and above) are white, waxy solids. This versatility across molecular weights makes PEG one of the most widely used polymer families in pharmaceutical, cosmetic, and industrial applications.
Polychem Industries supplies Polyethylene Glycol across multiple molecular weight grades in pharmaceutical and industrial quality to pharmaceutical manufacturers, cosmetic formulators, and industrial chemical companies across India and internationally. We stock and supply the full PEG range including PEG 200, PEG 300, PEG 400 (see our dedicated PEG 400 page for grade-specific details), PEG 600, PEG 1000, PEG 1500, PEG 4000, and PEG 6000 to suit your specific molecular weight requirements.
Available Grades
| Grade | Form | Purity | Standard | Applications |
|---|---|---|---|---|
| Pharma Grade | Liquid (PEG 200–600) or waxy solid (PEG 1000–6000) | 99%+ (Pharma Grade) | USP / BP / IP | Tablet coatings, suppository bases, ointment bases, laxatives |
| Industrial Grade | Liquid or solid (grade dependent) | 98%+ | Industrial | Lubricants, textile, ceramics, mould release agents |
Applications & Uses
Pharmaceutical Tablet Coating & Excipients
Higher molecular weight PEG grades (PEG 4000, PEG 6000) are used as plasticisers in tablet film coating formulations and as binders in tablet manufacturing, providing flexibility and improved coating film properties.
Suppository & Ointment Bases
PEG blends of different molecular weights are used to formulate suppository bases and ointment bases with specific melting point and consistency characteristics tailored to the intended therapeutic application.
Laxative Formulations
High molecular weight PEG (typically PEG 3350) is used as an osmotic laxative in bowel preparation products, working by retaining water in the colon through osmotic action without being significantly absorbed by the body.
Cosmetics & Personal Care
Various PEG grades are used across cosmetic formulations as emulsifiers, humectants, and solubilisers, with the specific molecular weight selected based on the desired texture, solubility, and functional performance in the formulation.
Industrial Lubricants & Mould Release
Industrial Grade PEG is used as a water-soluble lubricant in metalworking and as a mould release agent in rubber and plastic moulding operations, valued for its lubricity and easy water-washability.
Textile & Ceramic Processing
Used as a lubricant and processing aid in textile fibre treatment and as a binder in ceramic manufacturing processes, contributing to improved processing characteristics in these industrial applications.
