Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
According to Column 2 of 1907/2006/EC Annex VII this study does not need to be conducted on Cashmeran 'normal' as it is marketed in a non-solid or granular form.
Cashmeran FF consists of white crystals that are stuck together by the moisture in the test substance and looks like soda and its particle size distribution cannot be determined. It can be concluded that the substance does not consist of any particles of an inhalable size.
Additional information
Cashmeran exists in two forms, which are both mono-constituents. The Cashmeran 'normal' is a liquid and Cashmeran FF is a solid.
For Cashmeran 'normal' the granulometry cannot be performed. The granulometry of cannot be determined either for Cashmeran FF. It cannot be analysed by laser diffraction because the crystals are stuck together by the moisture in test substance. In addition, moisture droplets formed in a dispersing solvent, interfere with the measurement of particle size of the crystals. Sieving is not an alternative since the test substance sticks to the sieves. Based on this it is concluded that it is technically not possible to determine the particle size distribution of the test substance in the commercial form in which it was supplied.
Both forms of Cashmeran are marketed in a non-solid or granular form and therefore overall conclusion is that Cashmeran is treated as a liquid.
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.
