Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 the density of (benzoato-O,O')hydroxy(octadecanoato-O,O')aluminium has been estimated to be 1080 kg/m3 at 20.0 ± 1.0°C (relative density value 1.08).

Key value for chemical safety assessment

Relative density at 20C:
1.08

Additional information

As no data was available for the density 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 density of the read-across substance was determined in a proprietary, GLP-compliant air comparison pycnometer (for solids) test following OECD guideline 109 (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, being 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 density.
