An EFSA Panel has been deliberating on whether existing risk assessments of authorised acids, phenols, alcohols and various cations (lithium, copper, barium, cobalt and manganese) can be applied to their salts, or whether specific assessments are required to determine if the salts can be safely used in food-contact materials. The Panel considered the possible behaviour of the salts in the acidic environment of the human stomach, and determined that they should all dissociate with the exception of the copper salt of ethylenediamine tetraacetic acid (EDTA), which requires further investigation to determine the degree of its dissociation. Thus, for food-contact safety evaluations, it was concluded that the current risk assessments of authorised acids, phenols, alcohols and certain metal cations could also be applied to their salts, except for copper EDTA.
