The term glycol ether refers to a group of chemical solvents used in manufacturing and other industrial applications. Glycol ethers are alkyl ethers made from either ethylene oxide or propylene oxide. All offer a low molecular weight and high boiling point, making them stable when used as solvents or intermediaries. Most are biodegradable and water soluble.
E-Series vs. P-Series Glycol Ethers
Chemical manufacturers distinguish between P-series glycol ethers derived from propylene oxide and E-series ethers derived from ethylene oxide. Dow and Brenntag North America offer several products in each category. While different chemicals have different applications, typical uses for E-series glycol ethers include inks, dyes, paints, pharmaceuticals, and personal care products such as sunscreen. P-series products are used in cleaners and degreasers, aerosol paints, and other products.
Dow E-series glycol ethers include:
A coalescing solvent used in water-based architectural and industrial coatings, specialty printing inks, and certain agricultural pesticides. Also known as diethylene glycol n-butyl ether acetate, it has a chemical composition of C4H9O(CH2CH2O)2C(O)CH3 and offers a good balance between volatility and water solubility.
A solvent with a high boiling point and slow evaporating rate. Its chemical formula is C6H13OCH2CH2OH. Applications include solvent-based silk screen printing inks and industrial and household surface cleaners.
Some of the many P-series glycol ethers Dow manufactures include:
Or dipropylene glycol methyl ether. DOWANOL™ DPM is a hydrophilic, mid-to-slow evaporating solvent. It is most commonly used as a coupling agent in water-based dilutable coatings.
Or propylene glycol n-propyl ether. DOWANOL™ PnP is the company's most hydrophobic glycol ether that is still water soluble. Our customers often use it as a coupling agent in cleaning products or as a co-solvent in aerosol paint formulations, among other applications.
