Additional information
similar substance 1 is a multiconstituent substance composed by the acidic and the sodium salt forms of the same structure. The test was performed on the sodium salt of the Acid Red 097:1. The results on the tested substance are the following:
Growth rate inhibition (ErC50) and yield inhibition (EyC50) for the endpoint frond numbers was estimated to be 256 – 2560 mg/l nominal concentration.
Growth rate (NOErC) and yield (NOEyC) for the endpoint frond numbers were 25.6 mg/l nominal concentration, as determined by Dunnett's test.
Growth rate inhibition (ErC50)for the endpoint dry weight was estimated to be 256 – 2560 mg/l nominal concentration
Yield inhibition (EyC50) was estimated to be 25.6 – 256 mg/l nominal concentration.
Growth rate (NOErC) and yield (NOEyC) for the endpoint dry weight were < 25.6 mg/l nominal concentration, as determined by Dunnett's test.
Considering the high similarity between the structures and the composition of the substance, , Acid Red 097:2 is expected to show the same toxicity to aquatic plants as the sodium salt form.
According to the CLP Regulation (EC) n. 1272/2008, 'acute (short-term) hazard’ means for classification purposes the hazard of a substance or mixture caused by its acute toxicity to an organism during short-term aquatic exposure to that substance or mixture.
The result on aquatic plants confirm no concern for the aquatic compartment, therefore no classification is warranted under the CLP Regulation.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
