Description of key information

According to Annex XI of Regulation 1907/2006, testing for a specific endpoint may be omitted if testing does not appear to be scientifically necessary or if it is technically not possible to conduct the study as a consequence of the properties of the substance. Under REACH (ECHA 2017, Chapter R.7B – Endpoint Specific Guidance), the term ‘Hydrolysis’ refers to the “Decomposition or degradation of a chemical by reaction with water”, and this as a function of pH (i.e., abiotic degradation). In the case of the current substance, the chemical safety assessment will be based on elemental metal concentrations. For indicative behaviour in water - see IUCLID section 4.8 or CSR Section 1.3.
