Additional information

The main components of the submission substance are of inorganic nature, without any hydrolysable groups present. The substance finally will be completely dissociated into ions. Therefore, testing for hydrolysis is not considered scientifically justified. For the organic complex ligand humate, which comprise <1% (w/w) of the submission substance, a hydrolysis study according to Guideline C.7 was performed. This study showed that at all pH tested the half-time for hydrolysis is estimated to be >1 year.
