[Rationale for the Classification] Based on (1) to (6), since one isomer composing this substance, which is an isomer mixture, was regarded as a teratogen, and teratogenic effects were reported at the dose at which no marked maternal toxicity was observed, it was classified in Category 1B. Based on the new information source, the category was changed. [Evidence Data] (1) It was reported that, in a developmental toxicity study with pregnant mice dosed by gavage, in the intermediate-dose (10 mg/kg/day) group and the high-dose (25 mg/kg/day) group showing maternal toxicity, an increase in the incidence of malformations (cleft palate, open eyelids) was observed in fetuses (JMPR (1998)). (2) It was reported that, in a developmental toxicity study by dermal application to pregnant mice, in the highest dose (25 mg/kg/day) group showing no maternal toxicity, teratogenic effects including impaired otolith formation were observed in fetuses (JMPR (1998)). (3) It was reported that impaired otolith development, which was one of teratogenic effects in mice, was also seen in hamsters at doses that cause maternal toxicity, while in an oral administration test with rats, no teratogenicity was observed (JMPR (1998)). (4) It has been established that this substance (dinocap) is an isomer mixture and one isomer, 4-PP (2,6-dinitro-4-[(4RS)-octan-4-yl]phenyl (2E/Z)-but-2-enoate) is responsible for the teratogenic effects observed in mice and the other dinocap isomers, including DE-126 (meptyldinocap, CAS RN 131-72-6), do not share the teratogenic effects (EFSA (2014)). (5) In a developmental toxicity study with female mice dosed by gavage (4 to 25 mg/kg/day, days 6 to 15 of gestation) (about half of the mice in each group were killed on day 18 of gestation and the fetuses were examined. The remaining dams were allowed to naturally deliver and their liveborn pups were observed after birth), a decreasing trend of body weight gain (not significant) was only observed in dams at the high dose (25 mg/kg/day). However, in fetuses, at the intermediate dose (10 mg/kg/day) that causes no maternal toxicity, open eyelids (1/12 litters, one fetus) and cleft palate (3/12 litters, 4 fetuses) were observed, and at the high dose, open eyelids (2/9 litters, 3 fetuses) and an increase of cleft palate (7/9 litters, 65 fetuses) were observed. In naturally-delivered pups, there were an increased incidence of stillborn pups, decreased body weight gain and an increased incidence of litters with pups with head tilt or cleft palate (7 of 9 pups with cleft palate were from the same litter), and in a swimming test on day 43, abnormal swimming postures or ability were observed (JMPR (1998): Part II (Toxicological Evaluation)). (6) It was reported that, in a developmental toxicity study by dermal administration (1 to 25 mg/kg/day, days 6 to 15 of gestation, 4 hours/day) with female mice, local irritation at or above 10 mg/kg/day and one death at the highest dose of 25 mg/kg/day (the relation to the treatment is not clear) were observed in dams. As for developmental effects, it was reported that impaired otolith formation in addition to cleft palate (1/6 litters, 3 fetuses) and open eyelids (1/6 litters, 2 fetuses) was observed in fetuses in the highest dose group (JMPR (1998): Part II (Toxicological Evaluation)). [Reference Data, etc.] (7) In the EU, it was classified in Repr. 1B (EU CLP Classification Results (Accessed Dec. 2021)). |
