Hydrolysis
Administrative data
Link to relevant study record(s)
Description of key information
Hydrolysis is about 10 % at pH 7 after 5 days at 50 °C. The substance has a half-life time about one year at 25 °C pH 7.
Key value for chemical safety assessment
- Half-life for hydrolysis:
- 1 yr
- at the temperature of:
- 25 °C
Additional information
With the exception of the ready biodegradability data that is on Target Substance, the following data was obtained for Similar Substance 01 and Similar Substance 02 on hydrolysis and adsorption, respectively. It is expected that the Target Substance will present similar environmental behaviour Justification for the use of a read-across approach is provided in Section 13 of IUCLID.
The abiotic degradation of the aqueous solutions of the substance was evaluated on the basis of method and procedures outlined for the preliminary test into the OECD guideline 111. The concentration of the residual substance was determined by HPLC after 2.4 hours and 5 days. Less than 10 % hydrolysis was observed after 5 days in the test solution of pH 7.0; more than 10 % was hydrolysed in the test solutions of pH 4.0 and pH 9.0. Because the substance consists of a very complex mixture of structures, the results of a quantitative evaluation are widely scattered. Changes of the pH-values can affect the different components in various ways, not only by hydrolysis of (a) component (s) but for example also by influencing a protonation equilibrium which can cause changes of the extinction coefficient at a defined wave length.
Due to the chemical structure and functional groups presents, in the case of the substance hydrolysis can be considered as negligible degradation pathway. Hydrolysable organic groups are in fact those groups that can react with water like Esters, Anhydrides, Amides, Carbammates, Nitriles, Cyanates, Epoxides, Halomethanes, Alkylhalides, Urea and none of these groups are present within the commonly market substance formula.
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).
