Description of key information
Lactic acid will be present predominantly in aqueous compartments, will not bioaccumulate or bioconcentrate, and is rapidly biodegraded, therefore not persistent.
Additional information
Lactic acid will be present predominantly in aqueous compartments, will not bioaccumulate or bioconcentrate, and is rapidly biodegraded, therefore not persistent.
Physico-chemical properties of enantiomers are essentially identical, except for those dependent on a chiral environment (e.g. rotation of plane of polarization of polarized light, i.e. optical activity). See e.g. http://en.wikipedia.org/wiki/Enantiomer. Most if not all environmental fate processes take place in a non-chiral or 'racemic' environment, and thus will not discriminate between enantiomers. L- and D-lactic acid are both ubiquitous constituents of biological systems and are produced and metabolized a.o. by many bacteria. As such, both L- and D-lactic acid are completely biodegradable. Therefore, data for L-lactic acid are fully valid for D-lactic acid.
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.
