Effects on developmental toxicity

Description of key information

In a developmental toxicity study according to OPP 83-3 a structurally similar substance was administered to 25 female Sprague CD rats/dose by gavage at dose levels of 0, 100, 300, and 1000 mg/kg bw/day referring to 100 % active substance from day 6 through 15 of gestation. The maternal NOEL is 1000 mg active substance/kg bw/day, based on the lack of effects indicating maternal toxicity. Likewise, the embryotoxic NOEL is 1000 mg active substance/kg bw/day, based on the lack of embryotoxic effects up to the highest dose level. The teratogenic NOEL is 1000 mg active substance/kg bw/day. The partially unsaturated IQAC, DMS quaternised showed no teratogenic properties (no incidence of malformations). The observed variations were isolated without dose relation or lower than in the control group and were therefore not regarded as treatment related. The developmental toxicity study in the rat is classified acceptable and satisfies the guideline requirement for a developmental toxicity study (OPPTS 870.3700) in rats. These findings are further backed by the lack of adverse effects in a dose range finding study which was conducted up to a dose level of 1875 mg/kg bw/day.

Justification for classification or non-classification

Based on the findings of a reliable sub acute developmental toxicity study conducted on a structurally similar substance, classification of the substance is not justified.
