Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
In the presents of water, the substance aluminum;3-oxobutanoate (CAS 15598-24-0) will hydrolyze spontaneously and irreversible to the four components as listed below. Accordingly, the hazard assessment is based on information on these four hydrolyzation products. Since non of the hydrolyzation products are harmful or toxic to the environment, aluminum;3-oxobutanoate does not need to be classified as well.

Acetoacetic acid CAS 541-50-4
Acetoacetic acid acts as an intermediate in the mamal metabolism as well as in microorganisms. It is produced in mitochondria of the liver from acetoacetyl Coenzyme A (CoA). It is then released into the bloodstream as an energy source during periods of fasting, exercise, or as a result of type 1 diabetes mellitus. Furthermore, as it can be easily metabolized by all animals and is an natural occurring carbon acid, a high level of (bio)degradation in the aquatic compartment is expected. Thus, acetoacetic acid will be rapidly removed from the environment after hydrolysation of aluminum;3 -oxobutanoate.
2-Butanol CAS 78-92-2
Based on the read-across substance, methyl ethyl ketone (CAS No. 78-93-3), 2-Butanol is considered to be readily biodegradable (see ECHA disseminated dossier)
Thus, 2 -butanol will be rapidly removed from the environment after hydrolysation of aluminum;3 -oxobutanoate.
Methanol CAS 67-56-1
Methanol is readily degradable under both aerobic and anaerobic conditions in a wide variety of environmental media including fresh and salt water, sediments and soils, ground water, aquifer material and industrial wastewater. Thus, methanol will be rapidly removed from the environment after hydrolysation of aluminum;3 -oxobutanoate.
Aluminum hydroxide CAS 21645-51-2
As an inorganic susbtance aluminum hydroxide is not susceptible to biodegradation. However, according to the assessment published via the ECHA website, aluminum hydroxide is not classified for the environment. Thus, aluminum hydroxide does not contribute to a potential aquatic effect of aluminum;3-oxobutanoate.
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.
