Description of key information
Additional information
No data on aquatic toxicity are available on the substance itself, nevertheless some tests on a very similar substance are available (see read across justification for further details).
The data reported are:
Short-term toxicity to aquatic invertebrates: EC50, 48h = 0.031 mg/l
Toxicity to aquatic algae and cyanobacteria: EC50, 72h (growth rate) = 0.68 mg/l
According to the table 4.1.0 of the CLP Regulation (EC n. 1272/2008), a substance shall be classified as Aquatic Category Acute 1 (H400) when:
48 hr EC 50 (for crustacea) ≤ 1 mg/l and/or
72 or 96 hr ErC 50 (for algae or other aquatic plants) ≤ 1 mg/l.
Moreover, a substance shall be classified as Aquatic Category Chronic 1 (H410) when:
48 hr EC 50 (for crustacea) ≤ 1 mg/l and/or
72 or 96 hr ErC 50 (for algae or other aquatic plants) ≤ 1 mg/l
and the substance is not rapidly biodegradable
Based on the above results and the read across consideration Basic Violet 1 Acetate is classified H400: Very toxic to aquatic life and H410: Very toxic to aquatic life with long lasting effects.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
