Results and discussion
Results: maternal animals
Maternal developmental toxicity
- Details on maternal toxic effects:
- Maternal toxic effects:yes. Remark: slight local effects
Details on maternal toxic effects:
- General observations: neck lesions, red nasal exudate, and chromodacryorrhea in all groups (considered not to be test substance-related as these signs are common in animals that are collared)
- Local effects: mild dermal irritation including erythema and flaking of the skin in the treatment groups
- Body weight: similar to controls in both treatment groups
- Body weight gain: similar to controls in both treatment groups
- Uterine and net body weights: similar to controls in both treatment groups
- Food consumption: similar to control in both treatment groups; only difference (statistically significant) in high dose group on day 13-16: 31.5 g vs. 29.5 g (corresponding control data)
- Necropsy: no remarkable findings were observed
- Fetal status and uterine position: no parameter evaluated appeared to be adversly affected
- Clinical chemistry: no differences between treated and non-treated rats were observed

Results (fetuses)
- Details on embryotoxic / teratogenic effects:
- Embryotoxic / teratogenic effects:no effects
Details on embryotoxic / teratogenic effects:
- Fetal body measurements: Mean fetal body weights and crown-rump lengths, parameters of body growth and development were normal compared to controls.
- Fetal examination: No malformations or variations were observeed. Bruises were observed on the skin of 4 fetuses from the control group and 2 fetuses form the 800 mg/kg bw/day group (considered to be incidental). One fetus from one dam exposed to 800 mg/kg bw/day was pale in colour. No other remarkable findings were observed during external examination.
- Malformations (lumbar and sacral vertebrae, tail, sternebrae, and ribs) were observed. The incidence was low and there was no apparent dose-response relationship, these effects were considered to be not treatment-related. Comparable incidences of variant skeletal development were observed in both cotnrol and trated fetuses.
- Visceral examinations: A statistically significant (high dose) increase in the number of fetuses with levocardia was observed. The response appeared to be dose-related
Levocardia:
Litters: control: 0 (0%); 800 mg/kg bw/day: 2 (14.3%); 2000 mg/kg bw/day: 7 (50%); 14 litters per group examined
Fetuses: control: 0 (0%); 800 mg/kg bw/day: 3 (3.2%); 2000 mg/kg bw/day: 7 (10.1%); 94, 93, and 99 fetuses examined, respectively
Microphthalmia, anophtalmia and "apparent" hydronephrosis were also observed. Variant visceral development was observed in control and treated fetuses.

Any other information on results incl. tables
Levocardia was the only parameter affected in fetuses of dams treated with the test substance during gestation. In other studies, levocardia was observed in control fetuses, too. However, the effect of the test substance on heart development should be focused on in further studies as well as the impact, this effect has on postnatal survival.
Applicant's summary and conclusion
- Conclusions:
- In a developmental toxicity study, pregnant rats were dermally exposed to the test substance. No adverse effects were observed in any maternal or reproductive parameter nor on external and skeletal development of fetuses. Levocardia was observed in 3.2% and 10.1% of the fetuses exposed in utero to 800 and 2000 mg/kg bw /day, respectively. Thus, the developmental NOAEL was determined to be < 800 mg/kg bw.
