- Details on study design:
- The dose levels were chosen in consultation with the Sponsor. Based on available toxicity information, the acute oral lethal dose (LD50) of the test item in the rat was >2000 mg/kg and therefore, it was considered that there was no requirement to do any preliminary work. A high dose level of 1000 mg/kg bw/day was considered suitable for investigations with 250 and 500 mg/kg bw/day as the low and intermediate dose levels, respectively. The oral route was selected as the most appropriate route of exposure, based on the physical properties of the test item. The results of the study will aid dose level selection for subsequent studies.

Results and discussion
Results of examinations
- Clinical signs:
- no effects observed
- Description (incidence and severity):
- There were no clinical signs for any of the animals throughout the treatment period.
- Mortality:
- no mortality observed
- Body weight and weight changes:
- effects observed, treatment-related
- Description (incidence and severity):
- At the start of dosing period, males given the test item at 500 or 1000 mg/kg bw/day showed a slight reduction in group mean body weight gains when compared with controls. Subsequent recovery was apparent for males receiving 500 mg/kg bw/day such that body weight gains from Day 3 of dosing were similar to controls. Males given 1000 mg/kg bw/day also showed an improvement towards the end of dosing period with two out of three animals showing body weight gains comparable with controls over Days 5 to 8 of dosing. At 250 mg/kg bw/day, there was no effect of treatment on body weight development throughout the treatment period.
- Food consumption and compound intake (if feeding study):
- effects observed, treatment-related
- Description (incidence and severity):
- Males given the test item at 500 or 1000 mg/kg bw/day showed a slight reduction in food intake at the start of the dosing period when compared with controls. Thereafter, food intake for males receiving 500 mg/kg bw/day was similar to controls whereas for the high dose males it remained slightly lower than controls throughout the treatment period. At 250 mg/kg bw/day, food intake for males was similar to controls throughout the dosing period.
Food consumption for the treated females at all dose levels, in particular for the high dose animals, remained slightly lower than controls throughout the treatment period.
At all dose levels, food conversion efficiency for animals of either sex, in particular for the high dose animals, was generally lower than controls throughout the treatment period. It is worth noting that inter-group variation was high, reflecting high variation in body weight gain and/or food intake for these animals. - Food efficiency:
- not examined
- Water consumption and compound intake (if drinking water study):
- effects observed, treatment-related
- Description (incidence and severity):
- At all dose levels, treatment with the test item was related to increased water consumption in animals of both sexes. Despite high variation, inter-group differences were occasionally doserelated.

- not examined
- Haematological findings:
- not examined
- Clinical biochemistry findings:
- not examined
- Urinalysis findings:

Any other information on results incl. tables
Administration of XA31 to rats by oral gavage for seven consecutive days at dose levels of 250, 500 and 1000 mg/kg bw/day was well tolerated. There were no clinical signs for any of the animals throughout the study. Males given the test item at 500 or 1000 mg/kg bw/day and females at all dose levels showed body weight impairment that was associated with a reduction in food intake at the start of the dosing period. Subsequent recovery in body weight gain was apparent, however weight gain and food consumption for males receiving the high dose and females at all dose levels were still lower than controls towards the end of the dosing period. In the absence of any clinical signs or macroscopic findings, it is likely that these animals would have attained full recovery over time. At all dose levels, animals of both sexes receiving the test item showed a persistent and occasionally dose-related increase in daily water intake in comparison with controls.
Applicant's summary and conclusion
- Conclusions:
- The oral administration of the Reaction mass of AminoPhosphonium salt and Bisphenol AF (XA 31) to rats by gavage, at dose levels of 250, 500 and 1000 mg/kg bw/day for seven consecutive days was well tolerated. Based on the results obtained, a high dose level of 1000 mg/kg bw/day together with 100 and 300 mg/kg bw/day as low and intermediate dose levels, respectively, are considered to be suitable for use in a 28 day repeat dose toxicity study in the rat.
- Executive summary:
The objective of this study was to determine dose-levels of substance to be administered in the definitive study OECD guideline 407.
In this preliminary study of the repeated dose toxicity study 28 days, the Reaction mass of AminoPhosphonium salt and Bisphenol AF(XA 31) was administered by gavage to three groups, each of three male and three female han Wistar rats, for seven consecutive days, at dose levels of 250, 500 and 1000 mg/kg bw/day. A control group of three males and three females was dosed with vehicle alone.
During the study, clinical signs, body weight change, dietary intake, water consumption and macropathology investigations were undertaken.
As a result, there were no treatment-related unscheduled deaths during the study and no relevant clinical signs were observed. There were also no macroscopic changes at necropsy. However, the mean body weight gains and the food consumption for males receiving the high dose and females at all dose levels remained lower than the respective controls throughout the treatment period. Gravimetric measurement of water intake revealed increased water consumption for animals of both sexes at all dose levels.
In conclusion, the oral administration of the Reaction mass of AminoPhosphonium salt and Bisphenol AF (XA 31) to rats by gavage, at dose levels of 250, 500 and 1000 mg/kg bw/day for seven consecutive days was well tolerated. Based on the results obtained, a high dose level of 1000 mg/kg bw/day together with 100 and 300 mg/kg bw/day as low and intermediate dose levels, respectively, are considered to be suitable for use in a 28 day repeat dose toxicity study in the rat.
