Conclusion on classification
Classification, Labelling, and Packaging Regulation (EC) No. 1272/2008
Classification related information
Biodegradability: not readily biodegradable (OECD guideline 301F, 30 % biodegradation after 28 days)
Log Pow: 13.6742 at 20 °C (calculated by KOWWIN v1.68)
Aquatic acute toxicity
- Aquatic invertebrates: EC50 (48 h) = 350 mg/L (nominal, Daphnia magna, OECD 202)
- Algae: ErC50 (72 h) = 460 mg/L (nominal, Desmodesmus subspicatus, OECD 201)
- Fish: LC50 (96 h) > 100 mg/L (nominal, Danio rerio, OECD 203)
Aquatic chronic toxicity
- Algae: NOEC (growth rate, 72 h) = 18 mg/L (measured, Desmodesmus subspicatus, OECD 201)
Conclusion
The available experimental test data are reliable and suitable for classification purposes under Regulation 1272/2008. Sika Hardener LJ was found to be not readily biodegradable (please refer to IUCLID section 5.2.1). The log Pow was calculated to be 13.6742 at 20 °C (please refer to IUCLID section 4.7). The most sensitive test for the aquatic compartment was the test with fish (Danio rerio). The test revealed a 96-hour LC50 > 100 mg/L. Based on these results and the phisyco-chemical properties, Sika Hardener LJ is not classified for aquatic short-term (acute) toxicity, but is classified for aquatic long-term (chronic) toxicity in Cat. 4 according to Regulation (EC) No 1272/2008 (CLP), as amended for the fifteenth time in Regulation (EU) 2020/1182.
