Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Water solubility of aluminium tri-sec-butylate can not be determined as such as the substance reacts immediately with water in order to yield almost quantitatively sec-butanol and aluminium 3+ species, which do precipitate as white solid, resp. for a short period of time remain in a colloidal form (white suspension) as shown in a laboratory experiment. As surrogate for hazard and risk assessment supportive studies have been added indicating the solubility of sec-butanol formed (solubility in water 125000 mg/l at 20 °C resp. 181000 mg/l at 25 °C, matching rather well with 7.7% vol as reported in Merck Index).
Water solubility of the aluminium hydroxide, aluminiumhydroxyl oxide and aluminium is very low
Key value for chemical safety assessment
Additional information
Water solubility of aluminium tri-sec-butylate cannot be determined as such as the substance reacts immediately with water in order to yield almost quantitatively sec-butanol and aluminium 3+ species, which do precipitate as white solid, resp. for a short period of time remain in a colloidal form (white suspension) as shown in a laboratory experiment. As surrogate for hazard and risk assessment supportive studies have been added indicating the solubility of sec-butanol formed (solubility in water 125000 mg/l at 20 °C resp. 181000 mg/l at 25 °C, matching rather well with 7.7% vol as reported in Merck Index).
The water solubility of aluminium chloride, nitrate and sulfate is 3.9 -6.9 g/L. These aluminium salts are tested in some of the ecotoxicity studies included in the dossier (they represent a worst case scenario in view of exposure to aluminium(III) species).
For explanation for using surrogate data in a weight of evidence approach see section 13 IUCLID.
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.
