Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Administrative data
Description of key information
The LD50 value derived from the acute oral toxicity study with FeNaEDDHA is > 2000 mg/kg bw. The dermal LD50 is > 2000 mg/kg bw. The inhalation (4h) LC50 is > 4200 mg/m³ air.
Key value for chemical safety assessment
Additional information
Oral route
In two acute oral toxicity studies according to OECD Guideline 401 and GLP, the LD50 in albino rats and Sprague-Dawley CD strain rats was determined to be greater than 2000 mg/kg bw. Body weight development was not impaired. No deaths occurred in both studies.
Inhalation route
An acute inhalation toxicity study, according to OECD Guideline 403 was performed in albino rats. Upon a four-hour acute inhalation exposure and a 14-days post-treatment observation period, no mortalities were elicited by the test item at a concentration of 4202 ± 188 mg/m³. From the absence of mortalities it is concluded that the 4-h LC50 for both sexes is greater than 4200 mg/m³ air. The animals of both sexes exposed to the test article experienced the symptoms piloerection and dyspnoea to a similar extent. They recovered within 5 days. At autopsy, no deviations from normal morphology could be detected in all animals.
Dermal route
Two acute dermal toxicity studies (limit test), according to OECD Guideline 402 were performed with the test substance in albino rats and Sprague-Dawley CD strain rat.
All animals survived the 2000 mg/kg bw dermal application. No mortalities occured in both studies and body weight development was not impaired.
The acute dermal LD50 -values of FeNaEDDHA were considered to be greater than 2000 mg/kg bw.
Justification for classification or non-classification
The available experimental test data are reliable and suitable for classification purposes under Regulation (EC) No 1272/2008. As a result, the substance is not considered to be classified for acute oral, inhalation and dermal toxicity under Regulation (EC) No 1272/2008, as amended for the ninth time in Regulation (EU) No 2016/1179.
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.
