Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The substance is readily biodegradable (90% in 28 days) with acute toxicity data available for three trophic levels. The weighted average Log Pow value is 1.8 and indicative of a low potential for bioaccumulation. The lowest acute toxicity value from the three trophic levels relates to the algal study with EC50 (growth rate) values determined to be 33.14 and 6.29 mg/l for the two components of the test substance. The test substance is not classified for the environment based on acute toxicity data (> 1 mg/l threshold for classification).
The laboratory reported <10% adverse effects on growth rate for the two components with calculated geometric mean 72-hour EC10 values of 3.21 mg/l and 0.71 mg/l (4.6 mg/l nominal concentration). Both values are not biologically relevant for adverse effects on algal growth with a mean inhibition of growth at 4.7%. A mean reduced growth rate of only 6% was seen at the next highest nominal concentration of 10 mg/l. Substance stability in the test medium is low and the algal EC10 results for the two components of the test substance are not considered to be adequate for classification. The substance is rapidly biodegradable (meets the 10-day window) and not considered to pose a long-term hazard to aquatic organisms. The acute toxicity data for the three trophic levels of organism are relied upon for classification and the substance is not classified for the environment.
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.
