Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Aluminium trilactate is very soluble in water and dissociates toLactate and Aluminium in form of its cation.Thus, the read-across approach to Lactic acid and Aluminiumis justified in accordance withREACH Regulation (Annex XI, 1.5)by chemical structure and common physiological activity of the dissociation products.
Lactic acid has proven to be readily biodegradable. Thus, no further investigations of the degradations of Lactic acid are required (REACH regulation, annex VIII, 9.2.2.1).
According to REACH Regulation (Annex XI, 1) a study on phototransformation in air does not need to be conducted if the available data are sufficient for assessment. The atmosphere it not a target compartment for Aluminium trilactate. Due to the low vapour pressure (melting point > 300°C) of the substance, emissions to air are expected to be very low and the extent of photodegradation in air has no relevance for the environmental fate of Aluminium trilactate.
In general, abiotic degradation is not a relevant process for Aluminium as it is anorganic. According to REACH, “hydrolysis” refers to the “Decomposition or degradation of a chemical by reaction with water” (Guidance on information requirements and chemical safety assessment, Chapter R.7b).Aluminium is the most abundant metal in the lithosphere. Hydrolysis can change the chemical speciation of but not decompose or degrade Aluminium. Aluminium persists in the environment irrespective of its chemical speciation. Thus, hydrolysis is not relevant for the environmental fate of Aluminium trilactate.
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.
