Description of key information
Hydrolysis
The test item is a complex mixture for which the test guidelines for hydrolysis are not recommended. This is not only because components could have different hydrolytic rates but also hydrolysis products can be analytically indistinguishable from the starting components.
The test item as a whole was expected to be essentially insoluble in water (water solubility reported as < 0.13 mg/L). Therefore, the test solution concentration required that would dissolve all the components would be impractically low in order to perform the test and a sufficiently sensitive analytical method was not available. Overall, these issues would make hydrolysis testing unfeasible.
The main functional groups in the components of the test item which have the potential to hydrolyze are esters. Although esters usually hydrolyze readily, especially in alkaline conditions, some components of the test item may have a reduced hydrolytic potential due to them being essentially insoluble in water.
Biodegradation
No study is available for the substance itself, however a study is available for the read-across substance, Ethylene glycol, reaction products with polyisobutenyl succinic anhydride and hexadecenyl succinic anhydride, salts with dimethylethanolamine.
A study was performed to assess the ready biodegradability of the this material in an aerobic aqueous medium. The method followed that described in OECD TG 301C "Ready Biodegradability; MITI Test" referenced as Method C.4 -F of Commission Directive 92/69/EEC. The test material was prepared as an aqueous dispersion at a final concentration of 100 mg/L, inoculated with micro-organisms from a laboratory culture originating from 10 different sites throughout the UK and incubated in the dark at 25 +/-0.1 deg C for 28 days. The degradation of the test material was assessed by the measurements of oxygen consumption, DOC analyses on days 0 and 28 and compound specific analyses on days 0 and 28. Control solutions with inoculum and the standard material, aniline, were used for validation purposes.
The test material attained a mean of 38% degradation calculated from oxygen consumption values after 28 days. The mean degradation rate from the DOC analyses was 42%. The mean degradation rate from the residual test material analyses was 100 %. The test material cannot be considered to be ready biodegradable under the strict terms and conditions of OECD TG 301C as the degradation rate calculated from the oxygen consumption values was < 60%.
Adsorption coefficient
The adsorption coefficient of the test item was determined using the HPLC screening method, designed to be compatible with Method C19 Adsorption Coefficient of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 121 of the OECD Guidelines for Testing of Chemicals, 22 January 2001.
The test utilized a high performance liquid chromatograph. A commercially available cyanopropyl reverse phase HPLC column containing lipophilic and polar moieties was used.
The adsorption coefficient (Koc) of the test item has been determined to be > 4.27E+05, LogKoc > 5.63.
Additional information
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).
