Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
According to the REACh Regulation, Annex XI.3.2a, testing in accordance with Sections 8.6 and 8.7 of Annex VIII and in accordance with Annex IX and Annex X may be omitted, based on the exposure scenario(s) developed in the Chemical Safety Report.
The manufacturer or importer demonstrates and documents that all of the following conditions are fulfilled: (i) the results of the exposure assessment covering all relevant exposures throughout the life cycle of the substance demonstrate the absence of or no significant exposure in all scenarios of the manufacture and all identified uses as referred to in Annex VI Section 3.5(ii), a DNEL or a PNEC can be derived from results of available test data for the substance concerned taking full account of the increased uncertainty resulting from the omission of the information requirement, and that DNEL or PNEC is relevant and appropriate both to the information requirement to be omitted and for risk assessment purposes; (iii) the comparison of the derived DNEL or PNEC with the results of the exposure assessment shows that exposures are always well below the derived DNEL or PNEC.
As a basis for exposure-based waiving, the TTC concept as devised by Munro et al. [1] is applied.
Di-2 -EHTDG is predicted to fall within Cramer Class I (low hazard).
Within Cramer class I, the 5th-percentile NOEL have been identified from chronic oral studies or other oral studies (e.g., developmental toxicity) if they were more sensitive. The majority of NOELs were defined by studies in the rat.
The generic oral NOEL applicable to Di-2 -EHTDG (Class I) is 3.0 mg/kg bw/day. This generic NOEL is based on the most sensitive endpoint and also covers reproductive and developmental toxicity.

Short description of key information:
Reproductive toxicity testing has not been performed, because no significant exposure occurs in all scenarios of manufacure and identified uses.

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.
