- Details on study design:
- - Dose selection rationale: In a preliminary study with 20, 30, and 40 mg/kg bw/day 1 female died on day 1 of lactation in the high dose group. No further effects were observed in the parent and F1 generation. Furthermore in a 28-day study a NOAEL of 10 mg/kg bw/day was established for repeated dose toxicity. Thus, 20 mg/kg bw/day was chosen as the high dose level in the main study.
- Parental animals: Observations and examinations:
- CLINICAL OBSERVATIONS: Yes
- Time schedule: twice daily (before and after dosing) during the reatment period and once a day at the necropsy day
BODY WEIGHT: Yes
- Time schedule for examinations:
males: day 1, 8, 15, 22, 29, 36, and 43
females: day 1, 8, 15; day 0, 7, 14, and 20 of gestation; day 0 4 of lactation
FOOD CONSUMPTION:
- Food consumption for each animal determined and mean daily diet consumption calculated as g food/kg body weight/day: Yes
WATER CONSUMPTION: No - Oestrous cyclicity (parental animals):
- Vaginal smears were collected with swabs from all females in the morning (same time, everyday) from the initial dosing day to the day of successful copulation or end of the mating period to confirm the estrous cycle. The estrous cycle was classified into diestrus (D), proestrus (P), estrus (E) and metestrus (M). The mean estrous cycle and the number of estrous period during the test period were calculated.
- Sperm parameters (parental animals):
- Parameters examined in male parental generation: testis weight, epididymis weight
- Litter observations:
- PARAMETERS EXAMINED
The following parameters were examined in F1 offspring:
number and sex of pups, stillbirths, live births, postnatal mortality, presence of gross anomalies, weight gain, physical or behavioural abnormalities
GROSS EXAMINATION OF DEAD PUPS:
yes, for external abnormalities - Postmortem examinations (parental animals):
- SACRIFICE
- Male animals: All surviving animals at day 43
- Female animals: All surviving animals at day 4 of lactation

Reference
2 females of the 20 mg/kg bw/day group died on day 1 and 2 of lactation. Mass was noted in abdominal subcutis in one dam (0.8 mg/kg bw/day) from day 17 of gestation. This change was not judged to be treatment-related as there was no dose-dependency.
BODY WEIGHT AND FOOD CONSUMPTION (PARENTAL ANIMALS)
No significant difference was observed. High values of food consumption were observed in males of the high dose group on days 8 and 15, but was considered to be not toxicologically significant.
REPRODUCTIVE FUNCTION: ESTROUS CYCLE (PARENTAL ANIMALS)
No significant difference was observed.
REPRODUCTIVE FUNCTION: SPERM MEASURES (PARENTAL ANIMALS)
No significant difference was observed.
REPRODUCTIVE PERFORMANCE (PARENTAL ANIMALS)
No significant difference was observed. In one female of the high dose group no mating was confirmed (no histopathological finding in the ovary and testis/epididymides of the male counterpart were observed). Diestrus continued after cohabitation in 1 female of the 4 mg/kg bw/day group, which was seen as incidental.
ORGAN WEIGHTS (PARENTAL ANIMALS)
No significant difference was observed.
GROSS PATHOLOGY (PARENTAL ANIMALS)
Edema were found in the lungs of the death females. No further abnormaliteis were observed.
HISTOPATHOLOGY (PARENTAL ANIMALS)
Moderate and diffuse degeneration/necrosis in the myocardial cell, and moderate and diffuse inflammatory cellular infiltration in the myocardium were noted in the dead dams. In addition, mild/moderate and diffuse fibrosis in the myocardium was noted in the dams. In the alveolus of lung, moderate oedema was noted in the dead dams. In 9 surviving males and 7 surviving females of the high dose group similar effects were observed but in mild severity. Fibrosis in the myocardium was noted in 1 male and 6 females of the 20 mg/kg bw/day group.
Several changes were noted in all groups including the control group and were thus seen as incidental.
Low values of birth index were noted in 3 dams of the 20 mg/kg bw/day group (75%, 71.43%, and 72.73%). These changes were within the normal range of the historical control data and were judged as non treatment-related.
CLINICAL SIGNS (OFFSPRING)
No effects were observed.
BODY WEIGHT (OFFSPRING)
No effects were observed.
GROSS PATHOLOGY (OFFSPRING)
No effects were observed.

Additional information
3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluorooctyl 2-chloropropenoic acid ester (CAS 96383-55-0) was tested in Crl:CD(SD) rats in a reproduction/developmental toxicity screening study according to OECD 421 and in compliance with GLP (Saitoh, 2014). Twelve animals per dose were treated with 0.8, 4, and 20 mg/kg bw/d, respectively, 7 days per week. Male animals were treated for 42 days, beginning during the 15 days of the pre-mating period. Females were treated for a maximum period of 54 days, from 15 days of pre-mating period until day 3 of lactation. The doses were selected on the basis of data from a Dose Range Finding Study. After treatment with 20, 30, and 40 mg/kg bw/day 1 female died on day 1 of lactation in the high dose group. No further effects were observed in the parent and F1 generation. Furthermore in a 28-day study a NOAEL of 10 mg/kg bw/day was established for repeated dose toxicity. Thus, 20 mg/kg bw/day was chosen as the high dose level in the main study.
In the main study, females dosed with 20 mg/kg bw/d were found dead on day 1 and 2 of lactation, respectively. No further effects as clinical signs of toxicity were observed. No test item related influence on body weight development or body weight gain could be detected. High values of food consumption were observed in males of the high dose group on day 8 and 15, but were considered to be not toxicologically significant. No influence of the test substance was noted regarding the reproductive performance of the parental animals. Copulation index, fertility index, days until copulation, gestation length, number of corpora lutea or implantation sites, implantation index, delivery index, gestation index, parturition or maternal behaviour. In addition, no findings were reported after evaluation of sperm measures and estrous cycle. No effect on organ weight has been observed in any animal. Necropsy findings included oedema in the lungs of the death females. No findings were reported in the surviving animals.
Moderate and diffuse degeneration/necrosis in the myocardial cell and moderate and diffuse inflammatory cellular infiltration in the myocardium were noted in the dead dams after histopathological investigation. In addition, mild/moderate and diffuse fibrosis in the myocardium was noted in the dams. In the alveolus of lung, moderate oedema was noted in the dead dams. In 9 surviving males and 7 surviving females of the high dose group similar effects were observed but in mild severity. Fibrosis in the myocardium was noted in 1 male and 6 females of the 20 mg/kg bw/day group. Several other changes were noted in all groups including the control group and were thus seen as incidental.
In the examination of offspring, no changes attributed to the test substance were noted in the number of offspring, live offspring or stillborns, sex ratio, live birth index, viability index on day 4 or stillborn index. No abnormal findings attributed to the test substance were noted in the external features or body weights.
In conclusion, no adverse effects on reproductive toxicity were observed under the experimental conditions of the study. Therefore a NOAEL of 20 mg/kg bw was deduced for reproductive toxicity. Based on the mortality in the high dose group a NOAEL of 4 mg/kg bw/d was deduced for systemic toxicity. No effects on developmental toxicity of the F1 generation were observed based on the available information, indicating a NOAEL of 20 mg/kg bw/d for developmental toxicity.
Short description of key information:
Reproduction/developmental screening test, rats (OECD 421): NOAEL (fertility) = 20 mg/kg bw/d (highest dose tested)
Justification for selection of Effect on fertility via oral route:
The reliable GLP compliant OECD Guideline study was choosen (OECD 421).

Effect on developmental toxicity: via dermal route
- Endpoint conclusion:
- no study available
Additional information
In a study according to OECD 421 no effects on development have been observed with the test item. For further details refer to the discussion section "Effects on fertility".
Justification for selection of Effect on developmental toxicity: via oral route:
A study according to OECD 421 is available where no adverse effects were observed up to the highest dose tested (20 mg/kg bw/day). The screening infomation is sufficient to meet the standard information requirements of Regulation (EC) 1907/2006, Annex VIII, Column I, 8.7.1., but does not fulfill the criteria for a reliable assessment of the endpoint developmental toxicity according to Regulation 1272/2008/EC.
Justification for classification or non-classification
A reproduction/developmental toxicity screening study according to OECD 421 is available where no adverse effects on toxicity to reproduction and development were observed up to the highest dose tested (20 mg/kg bw/day). Although the screening infomation is sufficient to meet the standard information requirements of Regulation (EC) 1907/2006, Annex VIII, Column I, 8.7.1., it does not fulfill the criteria for a reliable assessment leading to a decision on classification or non-classification and labelling of the endpoint toxicity to reproduction/developmental toxicity according to Regulation 1272/2008/EC.
The available data on toxicity to reproduction/developmental toxicity of the test item are therefore inconclusive and insufficient for classification according to Regulation (EC) 1272/2008 or Directive 67/548/EEC.
