Additional information

Environmental Classification related key information for HiMo LABS:

 

Biodegradation in water: not readily biodegradable

Bioaccumulation: no potential to bioaccumulate; log Kow > 10 (EPISUITE QSAR calculation)

Water solubility: < 0.1 g/L (insoluble, EPISUITE QSAR calculation)

The Summary of Acute aquatic toxicity data for HiMo LABS:

For fish: 96h LC50 > 1.67 mg/L; LC50 > water solubility         

For invertebrates: 48h EC50 = 2.4 mg/L (RA from LABS); EC50 > water solubility         

For algae: 72h-EbC50 = 127.9 mg/L (RA from LABS);  EC50 > water solubility          

The Summary of Chronic aquatic toxicity data for HiMo LABS

For fish: 72d NOEC = 0.23 mg / L; NOEC > water solubility         

For invertebrates: 21d NOEC= 1.41 mg /L; NOEC > water solubility         

For algae: 72h-NOECb ≥ 2.4 mg/L (RA from LABS); NOEC > water solubility            

Conclusion on classification

Based on available acute and chronic aquatic data from analogue substances and EPISUITE QSAR modeling calculation, HiMo LABS is considered as an insoluble substance with EC50 and NOEC values higher than its predicted water solubility. It is therefore expected that the substance will not be toxic to freshwater or marine species. The substance has a very high predicted log Pow, but a very low predicted log BCF. It is therefore considered that the substance would not bioaccumulate in the environment. Based on the available data, the substance will be persistent in the environment.

On the basis of the data available and the known properties of the substance, the substance should be classified as category chronic 4, following section 4.1.2.6 of the CLP Regulation.
