Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Additional information
The biodegradability of isobutyl-(R)-lactate was calculated by QSAR estimation using EpiSuite 4.1/BIOWIN, Biowin 1–7. All sub-model results unequivocally predict that isobutyl-(R)-lactate is readily biodegradable (including anaerobic degradation); the predicted time frame for ultimate degradation is days to weeks. Due to the ready biodegradability, a study on hydrolysis was not conducted. Based on the low log Kow (0.73), the substance is expected to have low potential for adsorption to sediment and soil. In accordance with column 2 of REACH Annex VIII, the adsorption/desorption screening test has therefore not been conducted. In accordance with column 2 of REACH Annex IX, also a bioaccumulation study in aquatic or sediment species is not required because isobutyl-(R)-lactate has a low octanol-water partition coefficient (log Kow < 3), and thus a low potential for bioaccumulation.
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.
