Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
No toxic effects against Daphnia were observed at a limit test concentration of 100 mg/L. (Currenta, 2011)
Key value for chemical safety assessment
Fresh water invertebrates
Fresh water invertebrates
- Effect concentration:
- 100 mg/L
Additional information
Should read > 100 mg/L.
No effect was observed up to 100 mg/L; and hence EC50 is higher than 100 mg/L.The results are expressed in terms of Effective Loadings (EL). As the test item is a multi constituent and no information about the correlation between molecular weight and the structural formula of the test item are available, a Water Accommodated Fraction (WAF) was used to test effects at a limit concentration of 100 mg/L, and no specific analysis was performed. Desmodur RC / 100 is insoluble or poorly soluble, respectively, in water. Additionally, it hydrolyses quickly. Therefore a suitable selective and sensitive chromatographical method for the determination of the test item in aqueous solutions could not be established. The content of the test item during the exposure period was verified by DOC determination. (Currenta, 2011)
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.
