Glycol ethers are among the most extensively studied and best known chemical substances. They have been used widely since the twenties, enabling to gather considerable information through experience of use. In addition, in-depth studies have been carried out on them in order to best control the risks from their use. Glycol ether manufacturers are always ready to provide the public authorities with any information at their disposal.

Several joint experts’ reports have condensed the results of several hundreds of individual studies on glycol ethers:
