Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Ecotoxicity data are available forfrom short-term toxicity test on rainbow trout, short-term toxicity test on Daphnia magna and short-term toxicity test on Pseudokirchneriella subcapitata. Due to the Atlen SK nature (UVCB character, low water solubility) 100 mg/L Water Accommodated Fraction (WAF) ofwas tested in these studies. Available data show that solubility ofunder the conditions of the aforementioned tests was below <0.005 mg/L (which is the Limit of Detection of applied analytical method). Taking into account data from water solubility test it can be reasonably assumed that saturation concentration was achieved during preparation of relevant WAFs. In none of the aforementioned tests any effects were seen in the test organisms. In the light of these results it can be concluded that Atlen SK does not meet any LC50/EC50/IC50criteria for classification both under the CLP and the DSD.

Taking into account the fact that Atlen SK on the basis of results of ready biodegradability screening test is considered to be a readily biodegradable substance neither under the CLP nor under the DSD it should be classified with respect to environmental hazards.
