Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Conclusion on classification

The test item is a UVCB substance with constituents of different water solubility. This means that only a fraction of the total mass of the UVCB added to the test solution may be present in the WAF. The term "loading rate" in place of "nominal concentration" has therefore been advocated for expressing exposures of UVCBs that neither wholly dissolve nor completely form a stable dispersion or emulsion over the required test range (Girling et al., 1992). The loading rate is the mass to volume ratio of the UVCB to test medium used in the preparation of a WAF. Results should be calculated from the loading rates of the entire UVCB as either a median lethal loading (LL50), median effective loading (EL50) or 10 percentile effective loading (EL10) value. These loading levels from the WAF are used directly in the classification criteria (see also Annex I.4.5 of the CLP guidance document).
