Species, strain: rat, Sprague-Dawley ICO: OFA-SD (IOPS Caw).
Reason for this choice: rodent species generally accepted by regulatory authorities for this type of study.
Breeder: Iffa Crédo, 69210 L'Arbresle, France.
Number and sex: one group of ten animais (five males and five females).
Age/weight: on the day of treatment, the animais were approximately 6 weeks old, and had a mean body weight ± standard deviation of 182 ± 10 g for the males and 141 ± 5 g for the females.
Acclimatization: at least 5 days before the beginning of the study.
Identification of the animais: the animais were identified individually by earmarks or eamotches.
Environmental conditions
During the acclimatization period and throughout the study, the conditions in the animal room were set as follows:
.temperature: 21 ± 2°C
. relative humidity: 30 to 70%
. light/dark cycle: 12 h/12 h
. ventilation: approximately 12 cycles/hour of filtered, non-recycled air.
The temperature and relative humidity were under continuous control and recording. The records were checked daily and filed. In addition to these daily checks, the housing conditions and corresponding instrumentation and equipment are verified and calibrated at regular intervals.
The animais were housed in polycarbonate cages (48 cm x 27 cm x 20 cm). Each cage contained one to seven animais of the same sex during the acclimatization period and five rats of the same sex during the treatment period.
Each cage contained dust-free sawdust (SICSA, 94142 Alfortville, France).
Bacteriological and chemical analyses of the sawdust, including the detection of possible contaminants (pesticides, heavy metals), are performed regularly by extemal laboratories.
The results of these analyses are archived at CIT.
Food and water
Ali the animais had free access to A04 C pelleted diet (UAR, 91360 Villemoisson-sur-Orge, France), except as noted in "2.3.1 Fasting of the animais".
Each batch of food was analysed by the supplier for composition and contaminant levels. The diet formula is presented in appendix 2.
Drinking water filtered by a FG Millipore membrane (0.22 micron) was provided ad libitum. Bacteriological and chemical analyses of the water and diet, including the detection of possible contaminants (pesticides, heavy metals and nitrosamines), are performed regularly by extemal laboratories.
The results of these analyses are archived at CIT.
No contaminants were known to have been present in the diet, drinking water or bedding material at levels which may be expected to have interfered with or prejudiced the outcome of the study. - Route of administration:
- oral: gavage
- Vehicle:
- unchanged (no vehicle)
- Details on oral exposure:
- As the test substance was anticipated to be non-toxic at 2000 mg/kg, a limit test was performed by administering 2000 mg/kg of the test substance to one group of ten animais (five males and five females).
The test substance was administered undiluted, taking into consideration its specific gravity (0.91 g/ml).
The administration was performed in a single dose by oral route using a metal gavage tube fitted to a 1 ml plastic syringe (0.01 ml graduations).
The volume administered to each animal was adjusted according to body weight determined on the day of treatment. - Doses:
- 2000 mg/kg/day
- No. of animals per sex per dose:
- 5 males and 5 females
- Control animals:
- no
- Details on study design:
- Clinical signs and mortality :
The animais were observed frequently during the hours following administration of the test substance, for detection of possible treatment-related clinical signs. Thereafter, observation of the animais was made at least once a day until day 15.
Type, time of onset and duration of clinicat signs were reèorded for each animal individually. Time of death was recorded individually, in terms of the number of hours or days after dosing.
Body weight
The animais were weighed individually just before administration of the test substance on day 1 and then on days 8 and 15.
The body weight gain of the treated animais was compared to that of CIT control animais with the same initial body weight.
2.5 NECROPSY
On day 15, ail animais were killed by carbon dioxide asphyxiation and a macroscopic examination was performed.
After opening the thoracic and abdominal cavities, a macroscopic examination of the main organs (digestive tract, heart, kidneys, liver, lungs, pancreas, spleen and any other organs with obvious abnormalities) was performed.
In case of macroscopic lesions, organ samples were taken and preserved in 10% buffered formalin.
2.6 DATA EVALUATION
Evaluation of the toxicity of the test substance following a single oral administration in rats should include the relationship, if any, between the animais' exposure to the test substance and the incidence and severity of all abnormalities including behavioural and clinical abnormalities, macroscopic lesions, body weight changes, mortality and any other toxic effects. - Sex:
- male/female
- Dose descriptor:
- LD0
- Effect level:
- > 2 000 mg/kg bw
- Mortality:
- none
- Clinical signs:
- none
- Body weight:
- no effect
- Gross pathology:
- no finding
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Under our experimental conditions, the oral LD0 of the test substance RICINOLEATE DE METHYLE (batch No. 9802001) is equal to or higher than 2000 mg/kg in rats. No signs of toxicity were observed at this dose.
- Executive summary:
The acute oral toxicity of the testsubstance RICINOLEATEDEMETHYLE (batch No.9802001) was evaluated in rats according to OECD (No.401,24thFebruary1987) and EC (92/69/EEC,B.l,3lstJuly1992) guidelines.
The study was conducted in compliance with the principles of Good Laboratory Practice Regulations.
The test substance was administered by oral route (gavage) to one group of ten fasted SpragueDawleyrats(fivemalesandfivefemales).
The test substance was administered undiluted at the dose of 2000mg/kg, taking into consideration that its specificgravity was 0.91g/ml.
Clinical signs,mortality and bodyweight gain were checked for a period of up to 14days following the single administration of the testsubstance.
All animais were subjected to necropsy.
No death occurred at 2000mg/kg.The body weight was not affected by the treatment.
No apparent abnormalities were observed at necropsy in all animals.
Under our experimental conditions the LD0 is equal or higher than 2000 mg/kg in rats. No signs of toxicity were observed at this dose.

Additional information
Acute oral :
The acute oral toxicity of the test substance ricinoleate de methyle was evaluated in rats according to OECD guideline No. 401 and EU directive 92/69/EEC B.1. The substance was applied to ten (five male and 5 female) Sprague-Dawley rats at a dose of 2000 mg/kg bw. Animals were observed for 15 days. Mortality, reduction of body weight gain and abnormalities in gross pathology were not observed.
Justification for classification or non-classification
According to EU Directive 67/584/EEC and EU regulation (EC) No 1272/2008 (CLP) : ricinoleate de methyle is not classified for acute toxicity (oral and dermal).
Justification : LD 0> 2000 mg/kg bw
