Description of key information

A linear dependency of solubility on amount of the test item (nominal load) was perceived in the main test. As the solubility was dependent on nominal concentration, no exact value for the solubility of the test item in water can be stated. The concentration of K and B was in the range of 8.94 – 23.04 g/L and 12.80 – 25.04 g/L, respectively. The concentration of the test item in water calculated via measured concentrations of Boron as the main compound was stated as 65.73 – 128.6 g/L corresponding to 21.4 – 32.9 % dissolved part.

A dependency of pH values on amount of the test item (nominal load) was not perceived. No observations arousing doubts concerning the accuracy of the results and the validity of the study were made.

Key value for chemical safety assessment
