(Benzoato-O,O')hydroxy(octadecanoato-O,O')aluminium is considered to be readily biodegradable. This result is based on read across from aluminum, benzoate C16-18-fatty acids complexes which reached 79% degradation after 28 days, meeting the 10-day window, and therefore is considered to be readily biodegradable.
no data was available for the ready biodegradability 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 ready biodegradability of the read-across substance was
determined in a proprietary, GLP-compliant CO2 evolution test following
OECD guideline 301B (Harlan 2013). The study is considered reliable and
suitable for use for this endpoint. The results from this study also
indicate that the aluminium ion is not inhibitory to microorganisms, and
does not prevent the ready biodegradation of the organic component.
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(hexadecanoato-O,O')aluminium. The only
significant difference 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 adverse influence on ready
