Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The substance is inorganic and it does not have a biotic degradation.
The substance is stable in the environment, i.e. transformation or dissociation is not probable. It will behave like other stable minerals in the environment, such as many silicates or metal oxides, which will undergo very slow transformation by geological processes.
Like other environmentally stable minerals, TXAX released to the environment will not be bioavailable and thus will not become part of any biological system.
Therefore, a simulation test in soil would be unlikely to provide further evidence of potential ecotoxicity of the substance.
Key value for chemical safety assessment
Additional information
The substance is stable in the environment, i.e. transformation or dissociation is not probable. It will behave like other stable minerals in the environment, such as many silicates or metal oxides, which will undergo very slow transformation by geological processes. The substance consists of potassium, titanium and oxygen, all of which are abundant in the environment. Organisms can cope with these elements and have developed strategies to control the level of these elements in their bodies. However, since the substance is stable under environmental conditions, exposure to the elements as a reslut of environmental release and subsequent dissociation of the substance, is unlikely. Like other environmentally stable minerals, the substance, when released to the environment will not be bioavailable and thus will not become part of any biological system. Accumulation of the substance bound into the matrix of solid articles on soil, may only occur at appropriate landfills where worn articles are disposed of. release of the substance from these articles is very slow under environmental conditions. Therefore, a simulation test in soil would be unlikely to provide further evidence of potential ecotoxicity of the substance.
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.
