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.

Procedure and observations

The test item was administered orally by gavage to groups of 10 male and 10 female Wistar rats (F0 animals) at dose levels of 0 mg/kg body weight/day (corn oil served as vehicle), 100 mg/kg bw/d, 300 mg/kg bw/d and 1000 mg/kg bw/d. The duration of treatment covered a 2-week premating and a mating period in both sexes, approximately 1 week post-mating in males, and the entire gestation period as well as 4 days of lactation and 2 weeks thereafter in females. A detailed clinical observation was performed in all animals. Body weights and food consumption were determined in F0 animals. All animals were assessed by gross pathology; weights of selected organs were recorded and a histopathological examination was performed.

Clinical examinations, reproductive performance, clinical pathology, histopathology and gross pathology did not reveal any finding in treated animals. Viability, sex ratio and body weight of the pups was not affected. Examination of the ovaries and the uterine content did not overt any effect on uterus weight, number of implantations or resorptions.

Discussion

Thus, under the conditions of this Combined Repeated Dose Toxicity Study with the Reproduction/Developmental Toxicity Screening Test the oral administration by gavage to male and female Wistar rats did not reveal signs of toxicity. Thus, the no observed adverse effect level (NOAEL) for general systemic toxicity, for reproductive performance and fertility and for developmental toxicity is 1000 mg/kg bw.

Effects on developmental toxicity

Effect on developmental toxicity: via oral route
Endpoint conclusion:

Study duration:
subacute
Species:
rat
Effect on developmental toxicity: via inhalation route
Endpoint conclusion:
no study available
Effect on developmental toxicity: via dermal route
Endpoint conclusion:
no study available

Justification for classification or non-classification

Dangerous Substance Directive (67/548/EEC)

The available studies are considered reliable and suitable for classification purposes under 67/548/EEC. As a result the substance is not considered to be classified for reproductive toxicity under Directive 67 / 548 / EEC.

 

 

Classification, Labeling, and Packaging Regulation (EC) No. 1272/2008

The available experimental test data are reliable and suitable for classification purposes under Regulation 1272/2008. As a result the substance is not considered to be classified for reproductive toxicity under Regulation (EC) No. 1272/2008.
