Test animals
- Species:
- rat
- Strain:
- Sprague-Dawley
- Sex:
- male/female
- Details on test animals or test system and environmental conditions:
- 12 Sprague Dawley rats (SPF Caw) originated from IFFA CREDO were used after a 5 to 6-day acclimatation period. At the beginning of the study, the animals weighted between 167 g and 196 g (males) and between 149 g and 184 (females).
Group 1 (control) : 3 male rats: Rm2597 to Rm2599 and 3 female rats: Rf2586 to Rf2588
Group 2 (treated): 3 male rats: Rm2671 to Rm2673 and 3 female rats: Rf2656 to Rf2658
Environmental parameters for the treated group:
temperature: 20-23°C
relative humidity: 37-52%
Administration / exposure
- Route of administration:
- oral: gavage
- Vehicle:
- unchanged (no vehicle)
- Details on oral exposure:
- The animal of Group 2 received an effective dose of 2000 mg/kg body weight of product administred by forced-feeding under a volume of 2 ml/kg body weight using a suitable syring graduated fitted with an oesophageal metal cunula
- Doses:
- 2000 mg/kg body weight of product
- No. of animals per sex per dose:
- 3 male rats and 3 female rats
- Control animals:
- yes
- Remarks:
- Group 1 (control) : 3 male rats: Rm2597 to Rm2599 and 3 female rats: Rf2586 to Rf2588
- Details on study design:
- in order to minimize test volume variability in cases where the LD50 had to be determined, concentrations under investigation are adjusted so as to administer a constant volume of 2 to 10 ml/kg.
Variability in test volume should be minimised by adjusting the concentration to ensure a constant volume at all dose-levels. - Statistics:
- The value for LD50 and standard deviation are calculated for each sex and for the entire population (both sex together) using the parametric model for estimation of the LD50 using the probit analysis.

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The LD50 of the product is higher than 2000 mg/kg body weight by oral route in the rat.
According to the criteria for classification, packaging and labelling of dangerous substances in accordance with the E.E.C Directives 67/548 and 99/45, the product must not be classified - Executive summary:
The test item was administered to a group of 6 Sprague Dawley rats at the dose of 2000 mg/kg body weight. The experimental protocol was established according to the official method as defined in the O.E.C.D. Test Guideline No. 423.
No mortality was noted in the animals treated at the dose of 2000 mg/kg body weight.
the macroscopic examination of the animals at the end of the study did not reveal treatment-related changes.
In conclusion, the LD50 of the test item is higher than 2000 mg/kg body weight by oral route in the rat.
