Additional information
The 28 days study, performed on a Similar substance 01 and used in Read Across, followed the EU B.7 Guideline Repeated Dose (28 days) Toxicity (oral) and the OECD 407 Guideline, Repeated Dose 28 day Oral Toxicity Study in Rodents.
Based on the results of a 5 day range finding study, the dose levels for the 28 day toxicity study were selected to be 0, 50, 150 and 1000 mgl kg/day.
Treatment-related findings observed were as follows:
50 mg/kg/day:-No treatment-related findings.
150 mg/kg/day:- No treatment-related findings.
1000 mg/kg/day: No treatment-related findings.
From the results presented in this report a No Observed Adverse Effect Level (NOAEL) of 1000mg kg/day was established.
Based on the read-across principle (read-across from supporting substance -structural analogue or surrogate), the results can be considered for the repeated dose toxicity assessment of the substance. Justification for read-across is detailed in the report attached to the IUCLID section 13.
Justification for classification or non-classification
According to the CLP Annex 1: 3.9.2.8: effects considered not to support classification for specific target organ toxicity following repeated exposure are: small changes in clinical biochemistry, haematology or urinalysis parameters and/or transient effects, when such changes or effects are of doubtful or minimal toxicological importance.
28 days repeated oral administration to rats by gavage at the dose levels 50, 150 and 1000 mg/kg/day did not cause mortality.
No Observed Adverse Effect Level (NOAEL) of 1000mg kg/day was established.
Based on the read-across principle(read-across from supporting substance -structural analogue or surrogate), the result can be considered for the repeated dose toxicity assessment of the substance. Justification for read-across is detailed in the report attached to the IUCLID section 13.
As conclusion the registered substance is not classified for the oral repeated dose toxicity, according to CLP Regulation 1272/2008.
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.
