Description of key information
Additional information
Available information on the fate of 1,4-Butynediol in the environment indicates that the substance will not persist or bioaccumulate. It is readily biodegradable, is not expected to hydrolyze, and degrades in the atmosphere through reaction with OH-radicals with little or no potential for long-range transport. If released to soil, it has the potential to rapidly migrate to groundwater due to its low Koc, however rapid biodegradation will mitigate this movement.
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.
