Glycol Ethers

Glycol ethers are a group of solvents based on alkyl ethers of ethylene glycol commonly used in paints.  Glycol ethers are either “e-series” or “p-series” glycol ethers, depending on whether they are made from ethylene or propylene, respectively. Typically, e-series glycol ethers are found in pharmaceuticals, sunscreens, cosmetics, inks, dyes and water based paints, while p-series glycol ethers are used in degreasers, cleaners, aerosol paints and adhesives. E-series glycol ethers are higher in molecular weights, and can be used as intermediates that undergo further chemical reactions. P-series glycol ethers are generally high performance industrial solvents. Most glycol ethers are relatively water soluble, biodegradable and only a few are considered toxic. Therefore, they are unlikely to pose an adverse risk to the environment.
