Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Short term toxicity tests are available for all the three tropic levels (fish, invertebrates and aquatic plants). In an 96 h acute fish toxicity test, the test substance FAT 20043/C was observed to have 96 h LC50 to Zebra fish <1000 mg/L. 48 h EC50 value of FAT 20043/E to Daphnia magna was calculated to be 6.11 mg/L. The NOEC and EC0 value after 48 hours was determined to be 3.4 mg/I. The test material FAT 20043 is a dark-colored dye which when mixed in test medium will impart dark color to the test medium. Due to light absorption, colored substances such as dyes can inhibit algal growth, which is not the result of a toxic action. This shading effect can confound measures of chemical toxicity and thus impair the risk assessment. In an effort to avoid this problem Lemna gibba (Duckweed) Growth Inhibition test (Static) is conducted. In a GLP-compliant OECD 221 guideline study Lemna gibba (Duckweed) exposed to the test item FAT 20010/E recorded:
ErC50 based upon the frond numbers observed for a period of ‘7’ days for Lemna gibba was found to be >100 mg/L.
EyC50 based upon the frond numbers observed for a period of ‘7’ days for Lemna gibba was found to be >100 mg/L
ErC50 based upon the frond dry weight observed for a period of ‘7’ days for Lemna gibba was found to be >100 mg/L
EyC50 based upon the frond dry weight observed for a period of ‘7’ days for Lemna gibba was found to be >100 mg/L.
All fronds were found normal and healthy in all replicates of control and test concentration after 7 days leading to the end point being determined as ErC50 >100mg/L and EyC50 >100mg/L.
The toxicity to microorganisms of the test substance was determined in two studies prior to the publication of OECD guidelines in 1981. The resulting effect concentration is reported as >300 mg/l. Based on the above results the Daphnia study provides the lowest toxicity endpoint and therefore will be used for classification.
Additional information
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.
