Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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, (benzoato-O,O')hydroxy(octadecanoato-O,O')aluminium is considered to be non-flammable as it would fail to propagate combustion along 200 mm within 4 minutes. Experience in manufacture and handling shows that the substance does not ignite spontaneously on coming into contact with air at normal temperatures and is stable at room temperature for prolonged periods of time (days). Experience has also shown that the substance does not react with water. Therefore, the substance does not meet the criteria for classification as a flammable solid, a pyrophoric substance or a substance which in contact with water emits flammable gases.
Key value for chemical safety assessment
- Flammability:
- non flammable
Additional information
As no data was available for the flammability 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 flammability of the read-across substance was tested in a proprietary, GLP-compliant test following the method EC440/2008 A10 (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 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 flammability.
Justification for classification or non-classification
No classification is justified since (benzoato-O,O')hydroxy(octadecanoato-O,O')aluminium was determined to be non-flammable as it would fail to propagate combustion along 200 mm within 4 minutes. Experience in manufacture and handling shows that the substance does not ignite spontaneously on coming into contact with air at normal temperatures and is stable at room temperature for prolonged periods of time (days). Experience has also shown that the substance does not react with water. Therefore, the substance does not meet the criteria for classification as a flammable solid, a pyrophoric substance or a substance which in contact with water emit flammable gases.
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).
