As a consequence of the REACH dossier preparation, all available data on synthetic zeolites - as described by the Consortium registered by the Lead Registrant as Zeolite, cuboidal, crystalline, synthetic, non fibrous (see list of substances for more details) – have been thoroughly reviewed. Based on this evaluation the members of the Synthetic Zeolites Consortium have come to the conclusion that typical zeolites (non fibrous) covered by the Synthetic Zeolites Consortium can be classified as harmless and non-hazardous for all end-points. Yet some specific grades are classified but do not come into contact with consumers.

Since classic synthetic zeolites are not classified as hazardous or assessed to be PBT or vPvB, no exposure assessment is required for these substances. Moreover there is no obligation to communicate along the supply chain about uses and exposures according to the REACH-Regulation and to the Regulation (EC) No 1272/2008 on classification, labelling and packaging of substances and mixtures (CLP).
