Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The biodegradability of butyl-(S)-lactate was calculated by QSAR estimation using EpiSuite 4.1/BIOWIN, Biowin 1–7. All sub-model results unequivocally predict that butyl-(S)-lactate is readily biodegradable (including anaerobic degradation); the predicted time frame for ultimate degradation is days to weeks. Supporting information on the biodegradability suggests as well that butyl-(S)-lactate is readily biodegradable. Due to the ready biodegradability, a study on hydrolysis was not conducted. Based on the low log Kow of 1.1, 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.
The substance has a high water solubility. Due to its physicochemical properties, butyl-(S)-lactate will be present, remain, or distribute to, aqueous compartments, and will be rapidly degraded or metabolized there.
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.
