ECHA’s Biocidal Products Committee (BPC) concluded that the assessment of the following active substances does not support their approval for product-type 4 (food and feed area):

(*) silver zinc zeolite;
(*) silver zeolite;
(*) silver copper zeolite; and
(*) silver sodium hydrogen zirconium phosphate

For these existing active substances, the committee concluded that the risks are unacceptable for human health when activated carbon water filters with silver-containing active substances are used. People may be exposed through drinking water or food which has been prepared in filtered water. The substances can also be used to treat polymers, such as kitchen utensils like cutting boards. The evaluating competent authority for the applications is Sweden.
