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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
Adequate chronic toxicity data are not available for Set Retard Plus, therefore the aquatic toxicity assessment has been based on the short-term information available.
No adverse effects were recorded up to the tested concentration of 100 mg/l (nominal), in none of the organisms tested, i.e. fish, invertebrate and algae.
Conclusion on classification
According to the CLP Regulation (EC n. 1272/2008) the classification for aquatic acute toxicity follows the Table 4.1.0 a.
A substance has to be classified as Aquatic Acute 1 when:
96 hr LC50 (for fish) ≤ 1 mg/l and/or
48 hr EC50 (for crustacea) ≤ 1 mg/l and/or
72 or 96 hr ErC50 (for algae or other aquatic plants) ≤ 1 mg/l.
According to the CLP Regulation (EC n. 1272/2008) when no adequate chronic toxicity data are available, the classification criteria would be those reported into the Table 4.1.0 b(iii). However, Set Retard Plus is a readily biodegradable and not bioaccumulative substance; moreover, the short-term toxicity values recorded in all the organisms tested are outside of the classification thresholds, thus the substance does not meet the criteria to be classified for aquatic chronic toxicity.
Based on the result available for the three trophic levels the substance is considered as not classified for aquatic toxicity.
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.
