Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Aluminium triisopropylate dissociates into Al3+ species (Al(OH)2+, Al(OH)3 and Al(OH)4-) and isopropanol upon contact with water (see also section on hydrolysis, water solubility and pH in this dossier). As defined in Annex VII of the REACH regulation (1907/2006) , the study does not need to be conducted if the substance is inorganic such as the aluminium ions formed. Additionally, as stated in the book edited by Adams and Chapman (2006), "Bioaccumulation potential of metals cannot be estimated using log octanol-water partition coefficient (log Kow)." The aluminium cation moiety of the substance therefore cannot be assessed by this methodology. However, the direct dissociation product upon contact with water of this substance is isopropanol and the logKow of isopropanol is 0.05 as described in peer reviewed literature. This value is relevant for assessment of bioconcentration and is taken forward as surrogate value for risk assessment.
Key value for chemical safety assessment
- Log Kow (Log Pow):
- 0.05
- at the temperature of:
- 25 °C
Additional information
Aluminium triisopropylate dissociates into Al3+ species (Al(OH)2+, Al(OH)3 and Al(OH)4-) and isopropanol upon contact with water (see also section on hydrolysis, water solubility and pH in this dossier). As defined in Annex VII of the REACH regulation (1907/2006) , the study does not need to be conducted if the substance is inorganic such as the aluminium ions formed. Additionally, as stated in the book edited by Adams and Chapman (2006), "Bioaccumulation potential of metals cannot be estimated using log octanol-water partition coefficient (log Kow)." The aluminium cation moiety of the substance therefore cannot be assessed by this methodology. Also, aluminium is ubiquitous and the amount contributed by use of aluminium triisopropylate is negligible compared to soluble aluminium compounds in the environment. However, the direct dissociation product upon contact with water of this substance is isopropanol and the logKow of isopropanol is 0.05 as described in peer reviewed literature, indicative of no bioaccumulation potential.
The value for isopropanol is relevant for assessing behaviour in the environment and therefore is used as surrogate for aluminium triisopropylate.
For explanation for using surrogate data in a weight of evidence approach see also the document in 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.
