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 2008, 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 of the UVCB in water - see IUCLID section 4.8 or CSR Section 1.3.
