Endpoint summary
Administrative data
Description of key information
Acute oral toxicity studies (OECD 423) on the structural analogues MI3 and X14DesB30 both resulted in LD50 valus above 2000 mg/kg bw, as no lethaliiy occured at the highest dose levels of 2000 mg/kg bw. Thus, due to close structural similarity to these substances (especially X14DesB30 which also as inuslin human methyl ester binds to the inuslin receptor) low acute oral toxicity (LD50 > 2000 mg/kg) can be concluded for Insulin Human Methyl Ester as well.
Data obtained from an OECD 402 study on MI3 indicate very low acute dermal toxicity potential as LD50 > 2000 mg/kg bw. Thus, due to close structural similarity to MI3 an dermal LD50 > 2000 mg/kg bw can be concluded for Insulin Human Methyl Ester as well based on low -if any- dermal absorption of the substance.
For further read-across justification see document attached in section 13.

Additional information
Justification for classification or non-classification
Low acute toxic potential is concluded for Insulin Human Methyl Ester as oral and dermal LD50 values were concluded to be above 2000 mg/kg bw. Thus, Insulin Human Methyl Ester is not to be classified for acute oral - or dermal - toxicity according to the CLP-classification criteria.
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.
