Poly Ethylene Glycol 200/300/400/600 (PEG) – Manufacturer, Supplier & Exporter | DPRJ Universal

What is Polyethylene Glycol (PEG) used for?

PEG 200/300/400/600 grades are used in cosmetics and personal-care formulation, pharmaceutical excipients and ointment bases, hydraulic fluids, and metalworking fluid production.

What do the PEG grade numbers (200, 300, 400, 600) mean?

The number in each PEG grade (e.g. PEG 400) refers to its average molecular weight in g/mol; higher numbers indicate longer polymer chains and higher viscosity.

What is the general formula of PEG?

Polyethylene Glycol has the general formula H(OCH₂CH₂)_nOH, where n varies by grade to determine the molecular weight (200-600 g/mol for the liquid grades supplied).

Is PEG 200-600 a liquid or solid?

PEG grades 200 through 600 are clear, colorless to pale yellow liquids at room temperature; higher molecular weight PEG grades (above ~1000) are typically waxy solids.

How is PEG packaged for supply?

DPRJ Universal supplies PEG 200/300/400/600 in 230 Kgs drums, with bulk export packaging available on request.

Is PEG 200-600 soluble in water?

Yes, these lower-molecular-weight PEG grades are fully water-soluble and also soluble in many common organic solvents.

Is PEG safe for cosmetic and pharmaceutical use?

Yes, PEG grades in the 200-600 range are widely used as a base and humectant in cosmetics, pharmaceutical ointments, and personal care formulations.

What is the CAS number for PEG?

The general CAS Number for Polyethylene Glycol is 25322-68-3, with grade-specific CAS numbers available depending on molecular weight.

How does viscosity change across the PEG 200-600 grades?

Viscosity increases with molecular weight, so PEG 600 is noticeably more viscous than PEG 200.
