Key value for chemical safety assessment

Additional information

Solubility characteristics of the test item were investigated using the flask method, designed to be compatible with Method A6 Water Solubility of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 105 of the OECD Guidelines for Testing of Chemicals, 27 July 1995 (O'Connor & Woolley 2010).The nominal loading rate of 1.0 g/l confirmed that the test item was essentially insoluble in water, with less than 1.0 mg/l of each element being detected in solution with the exception of calcium (1.6 mg/l)
