Generally regarded as low‑hazard polyols. Hygroscopic—keep closed
to avoid moisture uptake. Spills are extremely slippery. Avoid
overheating (> 200 °C) to limit degradation. For pharmaceutical
uses, specify compendial grade (USP/Ph.Eur.).

• Humectant/solvent in personal care and HI&I.
• Plasticizer, lubricant and release agent in plastics/rubber. • Pharma excipient (ointments/bases), tablet lube/binder (compendial grades). • Carrier in agro and inks; heat‑transfer fluids (low‑toxicity blends). |
• Liquids (PEG 200–600): 200–230 kg drums • 1000–1250 kg
IBCs • bulk.
• Solids (PEG ≥1000): 25 kg bags • 500–1000 kg big bags. |
• Keep closed, dry and clean; avoid moisture pickup.
• Stainless steel recommended; avoid reactive soft metals at high temp. • Mix before use if partially solidified; heat gently (≤ 70 °C) to melt solids. |
