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.
