Test animals
- Species:
- rat
- Strain:
- Crj: CD(SD)
- Sex:
- female
- Details on test animals or test system and environmental conditions:
- TEST ANIMALS:
- Source: Charles River Laboratories, Research Models and Services, Sandhofer Weg 7, 97633 Sulzfeld, Germany
- Age at study initiation: approx. 8 weeks
- Weight at study initiation: 167 - 182g
- Fasting period before study: feeding was discontinued approx. 16 hours before administration; only tap water was then available ad libitum.
- Housing: during the 14-day observation period the animals were kept in groups of 3 animals in MAKROLON cages (type III plus). Granulated textured wood (Granulat A2, J. Brandenburg, 49424 Goldenstedt, Germany) was used as bedding material for the cages.
- Diet (ad libitum): commercial diet, ssniff R/M-H V1534 (ssniff Spezialdiäten GmbH, 59494 Soest, Germany)
- Water (ad libitum): drinking water
- Acclimation period: at least 5 days
ENVIRONMENTAL CONDITIONS:
- Temperature: 22°C ± 3°C (maximum range)
- Relative humidity: 55% ± 15% (maximum range)
- Air exchanges: 12 to 18- fold air change per hour
- Photoperiod (hrs dark / hrs light): 12/12
Administration / exposure
- Route of administration:
- oral: gavage
- Vehicle:
- other: 0.8% aqueous hydroxypropylmethylcellulose
- Details on oral exposure:
- VEHICLE
- Methocel; batch no. 11 A 27-N27, Fagron GmbH & Co., 22885 Barsbüttel, Germany
MAXIMUM DOSE VOLUME APPLIED: the administration volume was 10 mL/kg bw.
DOSAGE PREPARATION: the test substance was diluted to the appropriate concentration in the vehicle. - Doses:
- 2000 mg/ kg bw
- No. of animals per sex per dose:
- 6 female rats
- Control animals:
- no
- Details on study design:
- - Duration of observation period following administration: 14 days
- Frequency of observations and weighing: clinical observations were made 5, 15, 30 and 60 min, as well as 3, 6 and 24 hours after dosing and then daily for fourteen days. Observations on deaths were made at least once daily to minimize loss of animals during the study. Individual body weights were recorded before administration of the test item and thereafter in weekly intervals up to the end of the study. Changes in weight were calculated and recorded.
- Necropsy of survivors performed: yes
At the end of the experiments, all animals were sacrificed, dissected and inspected macroscopically. All gross pathological changes were recorded. Autopsy and macroscopic inspection of animals which died prematurely would have been carried out as soon as possible after exitus.
Histopathology was not carried out as no macroscopical findings were noted at autopsy.
- Statistics:
- No statistical analysis could be performed (the method used is not intended to allow a calculation of a precise LD50 value).
Results and discussion
Effect levels
- Sex:
- female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Remarks on result:
- other: mortality: 0/6, no signs of toxicity
- Mortality:
- No death was recorded within the test period.
- Clinical signs:
- other: Under the present test conditions, a single oral administration of 2000 mg octanoic acid, zinc salt, basic/kg bw to female rats did not reveal any signs of toxicity.
- Gross pathology:
- No pathological changes were observed at necropsy.
Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- LD50 (female rats) > 2000 mg/kg bw
According to the EC-Commission directive 67/548/EEC and its subsequent amendments, the test substance is not classified as acute toxic via the oral route.
According to the EC-Regulation 1272/2008 and subsequent regulations, the test item is not classified as acute toxic via the oral route.
