Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Conclusion on classification
Acute toxicity data for the test item are available for two trophic levels (aquatic invertebrates and algae). There were no effects observed up to the highest solubility of Lumilux® Yellow CD397 in test media (i.e., EC50 >46.1 µg/L for daphia magna and EC50 >40.6 µg/L for Raphidocelis subcapitata, respectively).
Long-term toxicity data for freshwater organisms are available for one trophic levels, i.t., algae. The chronic 72-h NOEC for Raphidocelis subcapitata is greater or equal to the highest solubility of Lumilux® Yellow CD397 in the test medium (NOEC≥40.6 µg/L).
Furthermore, Lumilux® Yellow CD397 is not readily biodegradable (0% within 28 days, OECD 301F) with an experimental logPow of 4.3 at 25°C/pH7.
Acute (short-term) aquatic hazard:
Unbounded EC50 up to the highest solubility in test medium (i.e., algae and aquatic invertebrates, respectively)
Since the 48h-EC50is < 1 mg/L, classification for ACUTE/SHORT-TERM AQUATIC HAZARD is required.
Chronic (long-term) aquatic hazard based on chronic & acute data and environmental fate of Lumilux(R) Yellow CD397:
Unbounded NOEC up to the highest solubility in test medium (i.e., algae)
Unbounded EC50 up to the highest solubility in test medium (i.e., algae and aquatic invertebrates, respectively)
Not readily biodegradable
logPow = 4.3
According to Regulation (EC) No. 1272/2008 and subsequent regulations Lumilux® Yellow CD397 does not require classification and labelling for acute aquatic hazard, since there were no acute effects observed up the highest solubility of the test substance in test medium.
According to Directive 67/548/EEC and its subsequent regulations Lumilux® Yellow CD397 does not require classification and labelling for chronic aquatic hazard. Although the test substance is poorly soluble in water, not readily biodegradable with a logPow of 4.3 at pH7 there were no chronic effects observed up the highest solubility of the test substance in test medium (i.e., NOEC≥40.6 µg/L for Raphidocelis subcapitata). Hence, no C&L for chronic aquatic hazard is required.
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.
