- Details on test animals or test system and environmental conditions:
- TEST ANIMALS- Source: Charles River Deutschland, Sulzfeld, Germany- Age at study initiation: Young adult animals (approx. 8 weeks old)- Weight at study initiation: 151 - 168g- Fasting period before study: Animals were deprived of food overnight prior to dosing and until 3-4 hours after administration of the test substance.- Housing: Group housing of 3 animals per cage in labeled Macrolon cages. - Diet: Free access to pelleted rodent diet (SM R/M-Z from SSNIFF® Spezialdiäten GmbH, Soest, Germany).- Water: Free access to tap water.- Acclimation period: At least 5 days ENVIRONMENTAL CONDITIONS (set to maintain)- Temperature (°C): 18 – 24- Humidity (%): 40 - 70- Air changes (per hr): at least 10 - Photoperiod (hrs dark / hrs light): 12/12
Administration / exposure
- Route of administration:
- oral: gavage
- Vehicle:
- other: 1% Aqueous carboxymethyl cellulose
- Details on oral exposure:
- GAVAGE METHOD: plastic feeding tubes.Frequency: single dosage, on Day 1.VEHICLE - Justification for choice of vehicle: The vehicle was selected based on trial preparations performed at WIL Research Europe and on test item data supplied by the Sponsor. There was no information available regarding the solubility or stability in vehicle.MAXIMUM DOSE VOLUME APPLIED: 10 mL/kg body weightDOSAGE PREPARATION: The preparations (w/w) were kept at room temperature and were dosed within 4 hours after adding the vehicle to the test item. Homogeneity was assessed by visual inspection of the solutions and the formulations were stirred during dosing, which ensures homogeneity sufficient for these kinds of studies. No correction was made for purity of the test item.
- Doses:
- 2000 mg/kg body weight
- No. of animals per sex per dose:
- 6 (2 groups of three females in a stepwise manner)
- Control animals:
- no
- Details on study design:
- - Duration of observation period following administration: 14 days - Frequency of observations and weighing:Mortality/Viability: Twice daily.Body weights: Days 1 (pre-administration), 8 and 15.Clinical signs: At periodic intervals on the day of dosing (Day 1) and once daily thereafter, until Day 15.- Necropsy of survivors performed: At the end of the observation period, all animals were sacrificed by oxygen/carbon dioxide procedure and subjected to necropsy. Descriptions of all internal macroscopic abnormalities were recorded.- Other examinations performed: none.
- Statistics:
- No statistical analysis was performed (The method used is not intended to allow the calculation of a precise LD50 value).
Results and discussion
Effect levels
- Key result
- Sex:
- female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Mortality:
- No mortality occurred.
- Clinical signs:
- other: Hunched posture was noted for all animals between Days 1 and 3. Additionally, piloerection and ptosis were noted for three animals on Day 1.
- Gross pathology:
- No abnormalities were found at macroscopic post mortem examination of the animals.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- In an acute oral toxicity study with rats, performed according to OECD 423 test guideline and GLP principles, a LD50 >2000 mg/kg bw was determined.
- Executive summary:
Licocare RBW 106 was tested in an acute oral toxicity study with 6 female rats at 2000 mg/kg bw, performed according to OECD 423 test guideline and GLP principles.
No mortality occurred. Hunched posture was noted for all animals between Days 1 and 3. Additionally, piloerection and ptosis were noted for three animals on Day 1. The body weight gain shown by the animals over the study period was considered to be similar to that expected for normal untreated animals of the same age and strain. No abnormalities were found at macroscopic post mortem examination of the animals.
Based on the results, a LD50 >2000 mg/kg bw was determined and the substance does not have to be classified according to Regulation (EC) No 1272/2008 on classification, labelling and packaging of items and mixtures (including all amendments).
