Description of key information
Data from a borated alkyl ester (CAS 63310-16-7) supporting the boric acid and glycerol functional groups was carried forward for the chemical safety assessment. In an OECD 301F study, 87% of the test material was degraded after 28 days.
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable but failing 10-day window
Additional information
The registered substance is a borated ester alkyl amide that hydrolyzes in water to the original starting materials: boric acid, glycerol and coconut fatty acid diethanolamide.Therefore, evaluating the biodegradation in water of the hydrolysis products is an appropriate approach to assessing biodegradation for the registered substance (CAS 1428353-74-5). Proprietary data for a borated alkyl ester (CAS 63310-16-7) supports that the boric acid and glycerol functionality from a borated ester is readily biodegradable but failing the 10 day window.
The remaining hydrolysis product, CAS 68603-42-9, is a fatty nitrogen derived (FND) amide. This category of chemicals was evaluated in an EPA Screening Level Hazard Characterization (Sept., 2010). There is sufficient data available to assess the biodegradation of this material in water. CAS 68603-42-9 is in subcategory 2, group B, of the FND amide category. In a closed bottle test, 51.8% of its theoretical BOD was achieved and was not considered readily biodegradable. However, in a separate test using two different initial concentrations, it achieved 71 and 84% of its theoretical BOD in 28 days and was classified as readily biodegradable. Additionally, 3 other subcategory members (CAS 142-78-9, 120-40-1 and 68140-00-1) were either inherently or readily biodegradable.
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
