Description of key information
Additional information
The fate of tetraethylene glycol in the environment is governed by its rapid reaction with photochemically-generated hydroxyl radical in the troposphere, and rapid biodegradation in the aquatic and terrestrial environments. The substance is not susceptible to degradation via direct photolysis or hydrolysis in the atmosphere or hydrosphere.
The physical/chemical properties of the tetraethylene glycol substance indicate a very clearly defined (expected) distribution in the environment. The substance exhibits very low vapor pressure, very low log Kow, and miscibility in water. The estimated log Kow and Koc values for this substance indicate a very low potential for adsorption to organic matter associated with soil, sediment, or wastewater bio-solids. This combination of properties dictates that the substance will remain associated with the aqueous phase of the environmental compartment(s) to which it is emitted, and that no evaporation to atmosphere will occur from water or soil.
The tetraethylene glycol substance exhibits a very low potential for bioaccumulation. The estimated log Kow value (-2.02) along with ready biodegradability, do not indicate a need for further assessment of bioaccumulation in the aquatic environment. Biodegradation screening studies indicate the potential for rapid and complete mineralization of the substance in aquatic and terrestrial compartments, and that the rate and extent of biodegradation are increased with prior exposure (adaptation) of microorganisms to the substance.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
