Correction, 20 October 2026. The publication date and the product-type-specific conditions have been clarified.
The European Commission approved silver zinc zeolite for biocidal product-types 2, 7 and 9 under Implementing Regulation (EU) 2024/2635. Adopted on 3 October 2024 and published on 4 October, the regulation sets an approval period from 1 March 2026 to 29 February 2036.
Product Types Covered
The approval covers specified disinfectants and algaecides, film preservatives, and preservatives for fibres, leather, rubber and polymerised materials. It is an active-substance approval with conditions, rather than authorisation of every finished biocidal product.
Treated-Article Conditions
The annex restricts non-textile polymer articles according to skin-contact area and age group. For product-types 2 and 9, treated textiles cannot be marketed if they may contact human skin, be handled wet or be mouthed by children under two. Product-type 9 additionally restricts textiles that may be used outdoors.
For product-type 7, separate conditions concern paints and coatings for outdoor infrastructure and structures above water. The annex also specifies treated-article labelling duties. The conditions must therefore be read against the relevant product type.
