Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

SUMMARY OF AVAILABLE DATA (key values)

Acute toxicity to aquatic organisms (pelagic):

- Freshwater fish (Danio rerio): 96h-LC50 > 12.9 mg solid content/L (limit test);

- Marine fish (Scophthalmus maximus): 96h-LC50 > 4.8 mg solid content/L (limit test);

- Marine crustacean (Acartia tonsa): 48h-EC50 = 20 mg active content*/L;

- Freswater algae: no data;

- Marine algae (Skeletonema costatum): 72h-EC50 = 5.1 mg active content*/L.

*As an EC50 value expressed in solid content was not reported, the EC50 value expressed in active content was used as a worst-case for the assessment.

Chronic toxicity to aquatic organisms (pelagic):

- Fish: no data;

- Marine crustaceans: no data;

- Freshwater algae: no data;

- Marine algae (Skeletonema costatum): 72h-NOEC = 3 mg active content*/L.

*As a NOEC value expressed in solid content was not reported, the NOEC value expressed in active content was used as a worst-case for the assessment.

Other ecotoxicity data:

- Aquatic microorganisms (freshwater, activated sludge): 3h-EC50 = 1182.7 mg solid content/L and 3h-EC10 = 379.5 mg solid content/L;

- Sediment organisms (marine water, amphipods): 10 -LC50 > 4408.5 mg active content/L.

Environmental fate:

- Rapidly degradable in the environment (more than 60% mineralization in 28 days in a biodegradation test in seawater);

- Low bioaccumulation potential (based on log Kow < 4).

All effective concentration are expressed in solid content (or in active content) and are relevant for the REACh-registered substance (= active content + minor constituents + impurities). According to the CLP criteria for hazard classification, the substance EC 242-893-1 does not have to be classified for acute and chronic environmental hazards.
