Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additiv 104 can be considered insoluble in water, and in addition a substance made of multiple components of very high molecular weights and thus likely not bioavailable to create toxic effects. The hazard classification (R-51/53 or GHS 4 -11) comes from the most sensitive of 3 acute tests on freshwater organisms (Daphnia 48 -hr EC50/NOEC = 6.8/3.6 mg/L, respectively; when fish and algae showed that the acute endpoints were in excess of 10 mg/L). The aquatic tests were conducted as water accommodated fractions or WAFs, and owing to the complexity of the substance and inherent properties the analytical verifications have been based on indirect measurements.

Releases to the environment under normal conditions are minimal, and hence releases due to spills should be limited and easily contained for proper disposal. Al

hough the estimated concentrations have only limited relevance to the actual concentrations, a screening assessment indicates that the substance is less hazardous than what is assigned by GHS, and until better proof can be generated the conservative classification can be considered sufficient.
