Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Effects on fertility
Additional information
Male and female rats were exposed to 0 or 10000 ppm of the substance via inhalation for 90 days. No histopathological or weight changes were observed in reproductive organs. Based on this information, the NOAEL for effects on reproductive organs was 10000 ppm, which was the highest concentration tested.
Male and female dogs were exposed to 0 or 5000 ppm of the substance via inhalation for 90 days. No histopathological or weight changes were observed in reproductive organs. Based on this information, the NOAEL for effects on reproductive organs was 5000 ppm, which was the highest concentration tested.
Effects on developmental toxicity
Additional information
In a developmental toxicity study, pregnant rats were exposed by inhalation to 0, 5000, 20000 or 50000 ppm of the test substance for 6 hours per day, on days 7-21 of gestation. The maternal and developmental no-observed-effect level (NOEL) was 50000 ppm, which was the highest concentration tested.
Justification for classification or non-classification
The test substance did not adversely affect reproductive organs in 90-day studies in rats and dogs, and did not produce adverse developmental effects at any dose level tested in a rat prenatal developmental toxicity study. The substance does not need to be classified for developmental toxicity according to the EU Directive 67/548/EEC. However, due to the lack of a dedicated reproductive toxicity study, the substance cannot be classified for reproductive toxicity according to EU Directive 67/548/EEC and EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation (EC) No. 1272/2008.
Additional information
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.
