Molecular Weight PEG 400 – ~380–420 g/mol ; PEG 4000 – ~3000–3700 g/mol ; PEG 6000 – ~7000–9000 g/mol

Regulatory Compliance USP / NF / EP / BP / JP / FCC (as applicable)

Manufacturing Suitability Suitable for oral, topical, injectable (PEG 400), cosmetic, and industrial formulations

Storage Conditions Store in a tightly closed container at room temperature, in a cool, dry, well-ventilated area, away from moisture and direct sunlight.

Certifications GMP, ISO 9001:2015, FSSC 22000 (for food-grade material if applicable)

Availability On-demand production / Global supply capability

HS Code 3907.20.00 – Polyethers

Excipient Technical Profile

Appearance • Low MW (PEG 200–400): Clear, colorless, viscous liquid • Medium MW (PEG 1000–1500): Semi-solid, soft wax • High MW (PEG 4000–6000 & above): White to off-white flakes or powder

Bulk Density PEG 4000–6000: ~0.45 – 0.70 g/cm³ (loose, depends on particle form)

Solubility Freely soluble in water; Soluble in ethanol, acetone, chloroform; Practically insoluble in aliphatic hydrocarbons (e.g., hexane)

Melting Point (Approximate, MW dependent) PEG 400: ~4–8 °C PEG 4000: ~53–58 °C PEG 6000: ~60–63 °C

FAQs

PEG is widely used as a pharmaceutical excipient, solvent, plasticizer, and ointment base, as well as in cosmetics, food, and industrial applications.

Yes. Pharmacopoeial grades of PEG (USP/BP/EP) are considered safe and biocompatible when used within prescribed limits.

Lower molecular weight PEGs are liquids, while higher molecular weight PEGs are semi-solid or solid, with higher melting points and viscosity.

PEG is freely soluble in water and also soluble in alcohols and many organic solvents, but insoluble in aliphatic hydrocarbons.

PEG should be stored in well-closed containers, protected from excessive heat, moisture, and direct sunlight to maintain product stability.
