Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Endpoint summary
Administrative data
Description of key information
EC50 (48h) in aquatic invertebrates: 0.26 mg/l based on measured concentrations
EC50 (7d) in aquatic plants other than algae: 1.347 mg/l
Additional information
Studies on aquatic invertebrates and on aquatic plants were used to assess the toxicity to the aquatic compartment.
In both cases, toxic effects were seen and EC50 levels were identified.
Decision on classification
According to the CLP Regulation (EC 1272/2008), studies on aquatic invertebrates, aquantic plants and fish are used for classification. Classification for acute aquatic hazard applies when:
Category Acute 1
96 hr LC 50 (for fish) ≤ 1 mg/l and/or
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.
When no chronic toxicity data is available and the substance is not rapidly degradable and/or experimentally detrmined BCF >= 500 (or if absent, the logPow >=4):
Category Chronic 1
96 hr LC 50 (for fish) ≤ 1 mg/l and/or
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.
Category Chronic 2
96 hr LC 50 (for fish) > 1 to ≤10 mg/l and/or
48 hr EC 50 (for crustacea) > 1 to ≤10 mg/l and/or
72 or 96 hr ErC 50 (for algae or other aquatic plants) > 1 to ≤10 mg/l
Overall, based on results on aquatic invertebrates, Acid Red 111 is classified for both acute and chronic toxicity as H400 (acute 1) and H410 (chronic 1).
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.
