Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Conclusion on classification
No constituents have acute toxicity at the limit of solubility, therefore no Acute classification for the environment is required.
The substance is classified Category Chronic 3 for the environment. This conclusion is reached whether a toxic units method based on contribution of the constituents present, or the additivity method for mixtures from the CLP regulation, is applied.
1) Using the toxic units method (refer to Section 6.1.4 in IUCLID): Loading rate 0.17 mg/l whole substance gives a TU of 1. Since the constituents are rapidly degrading this result therefore meets the critiera for classification as aquatic category Chronic 3.
2) Criteria are defined in the CLP Regulation based on the classifications and proportions of the constituents. The following condition is met, indicating the mixture should be classified as category Chronic 3 (the criteria for mixture Chronic 1 or 2 are not met): Sum of components classified as: (M×100×Chronic 1) + (10×Chronic 2) + Chronic 3≥25 %.
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.
