Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Four types of Zeolites were tested for hydrolysis. As the amounts of Si and Al after five days were more than 90% of the amounts at the start of the tests in pH 4 and 7 buffer solutions, the test items were considered to be hydrolytically stable.
As Zeolite is an inorganic substance, no risk for adsorption potential neither for water, sediment nor soil is expected. The actual adsorption of type A zeolite Sylosiv A4 on soils was not determinable.
Due to its inherent chemico-physical properties, the uptake of zeolite, cuboidal, crystalline, synthetic, non-fibrous is low and no potential risk for bioaccumulation is to be expected.
This is also confirmed by studies in dissolution which show that synthetic zeolites are almost identical to natural ones in respect of environmental fate and behaviour.
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
