Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Based on read across from aluminum, benzoate C16-18 fatty acids complexes, the surface tension of a 90% saturated aqueous solutions is estimated to be 72.6 mN/m at 20.0 ± 0.5°C. (Benzoato-O,O')hydroxy(octadecanoato-O,O')aluminium is considered not to be surface active.
Key value for chemical safety assessment
- Surface tension:
- 72.6
Additional information
As no data was available for the surface tension of (benzoato-O,O')hydroxy(octadecanoato-O,O')aluminium, the endpoint was read across from the substance aluminum, benzoate C16-18-fatty acids complexes. The surface tension of the read-across substance was determined in a proprietary, GLP-compliant ring balance test following OECD guideline 115 (Harlan 2013).
Aluminum, benzoate C16-18-fatty acids complexes (CAS No. 94166-87-7, EC No. 303-385-6) is considered suitable for read across to (benzoato-O,O')hydroxy(octadecanoato-O,O')aluminium as it is structurally similar being an approximate 2:1 mixture of (benzoato-O,O')hydroxy(octadecanoato-O,O')aluminium and (benzoato-O,O')hydroxy(hexadecanoato-O,O')aluminium. The only significant difference therefore is the presence of about 30% of the aluminium complex containing the saturated C16-fatty acid, hexadecanoate, in place of the saturated C18-fatty acid, octadecanoate. This small difference in composition is expected to have no influence on surface tension.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
