Additional information
Biodegradation in water
The ready biodegradability of 1,3 -butanediol was studied in a Modfied Sturm Test following OECD 301B. The test substance was degraded to 81% (CO2/ThCO2) after 29 days. The 10 -days window was met. The validity criteria were fulfilled. 1,3 -Butanediol is readily biodegradable according to OECD criteria (Barnes, 2000).
Simulation tests:
No data on degradation in soil and in water/sediment simulation tests are available (not necessary for REACH, since substance is readily biodegradable).
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.
