Glycol ethers

Glycol ethers are a group of solvents based on alkyl ethers of ethylene glycol or propylene glycol commonly used in paints and cleaners. These solvents typically have a higher boiling point, together with the favorable solvent properties of lower-molecular weight ethers and alcohols.

Chemistry

Glycol ethers are either derived from ethylene glycol or propylene glycol. They are solvents that have both ether and alcohol functionalities. The structure of glycol ethers generally includes an alkyl group bonded to an oxygen atom, which is in turn bonded to a carbon atom. The carbon atom is part of a larger hydrocarbon group, which can vary in size and structure.

Uses

Glycol ethers are used in a wide variety of applications, including paints, inks, cleaners, and hydraulic brake fluids. They are also used in the electronics industry as solvents for resins, oils, and other substances. In the pharmaceutical industry, glycol ethers are used as solvents for the production of drugs and other medicinal products.

Health Effects

Exposure to high levels of glycol ethers can lead to a range of health effects, including irritation of the skin, eyes, nose, and throat, as well as more serious effects such as kidney damage and anemia. Some glycol ethers have been classified as potential human carcinogens by the International Agency for Research on Cancer (IARC).

Safety

Due to their potential health effects, the use of glycol ethers is regulated in many countries. Safety measures include using appropriate personal protective equipment, ensuring good ventilation, and following safe handling procedures.
