ACMA00016414
Product Name
Polyethylene Glycol 600
Description
Ethylene glycol is a clear, colorless syrupy liquid. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. Since it is a liquid it can easily penetrate the soil and contaminate groundwater and nearby streams.;Liquid; WetSolid;PEG 400 is a clear, viscous, colourless or almost colourless hygroscopic liquid; PEG 3000, PEG 3350, PEG 4000, PEG 6000 and PEG 8000 are white or almost white solids with a waxy or paraffin-like appearance;Liquid;ODOURLESS COLOURLESS VISCOUS HYGROSCOPIC LIQUID.;COLOURLESS VISCOUS SLIGHTLY HYGROSCOPIC LIQUID.;Clear, colorless, syrupy, odorless liquid.;Clear, colorless, syrupy, odorless liquid. [antifreeze] [Note: A solid below 9°F.];Clear, colorless, syrupy (viscous) liquid at room temperature. Often colored fluorescent yellow-green when used in automotive antifreeze.
