Description of key information
The biodegradation of 3-Methyl-1,3-Butandiol was assessed in a Guideline study and found to be
BOD: 94%
TOC: 98%
GC: 100%
Therefore 3-Methyl-1,3-Butandiol is considered to be Readily Biodegradable.
The hydrolysis of 3-Methyl-1,3-Butandiol was assessed at pH 4, 7 and 9 and 50 ± 0.5°C, less than 10% hydrolysis had occurred after 120 hours (5 days), equivalent to a half-life of greater than 1 year under environmental conditions (25°C). Therefore the test item was determined to be hydrolytically stable under acidic, neutral and basic conditions.
The test item was found to have a log10Kocvalue of less than 1.3.
Additional information
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.
