Is there ecological and toxicological data on Dow glycol ethers available?
Biodegradation of Glycol Ethers Biodegradation is an important aspect for assessing the ecological performance of chemical substances. Biodegradation of chemicals is a complex process and is influenced by a number of factors, such as: • chemical structure of the substance • concentration of the substance • availability of oxygen • origin of the microorganisms • concentration of microorganisms • type and concentration of nutrients • “contact time” • temperature • pH value. The Organization for Economic Cooperation and Development (OECD) has set up a number of standardized test methods for biodegradation, based on various principles. Dow has performed biodegradation tests according to these OECD test methods, in house or at contract laboratories. Most of the tests were carried out according to good laboratory practice (GLP). See the Technical Data Sheet below for specific test information and data. Air Quality Under current legislation, glycol ethers are considered 100% volatile organic
