Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Maximum mass loss = 35.6 ppm at 37 °C, pH 7 (ICP analysis);
Maximum mass loss = 58.1 ppm at 37 °C, pH 5.5 (ICP analysis);
Maximum mass loss = 148.4 ppm at 37 °C, pH 8.0 (ICP analysis)
Key value for chemical safety assessment
Additional information
This analysis does not follow any of the recommended guidelines. Instead, the test item is digested for two hours at ca. 37 °C and the solubilized material is then quantitated by means of ICP. Three diferent digestion buffers were used (deionized water, pH 5.5 and pH 8).
The water solubility is given in terms of maximum mass loss of the test material. This magnitude represents the sum of all constituents mass losses measured by ICP and it is expressed in parts per million (ppm) of solubilized constituent.
| Extraction solution | DI water | pH = 5.5 buffer | pH = 8 buffer |
| Soluble S, ppm | < 7.5 | < 7.5 | 19 |
| Soluble Sn, ppm | 2.2 | 1.7 | 75 |
| Soluble Zn, ppm | 20 | 43 | 48 |
| Soluble Ti, ppm | < 5.4 | < 5.4 | 5.9 |
| Soluble Nb, ppm | < 0.5 | < 0.5 | < 0.5 |
| Maximum mass loss, ppm | 35.60 | 58.1 | 148.4 |
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.
