Additional information

As no data was available for the vapour pressure 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 vapour pressure of the read-across substance was determined in a proprietary, GLP-compliant vapour pressure balance test (Harlan 2013) following OECD guideline 104.

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 vapour pressure.
