24 hours
Doses:
2000 mg/kg
No. of animals per sex per dose:
5 males and 5 females
Control animals:
no
Details on study design:
- Duration of observation period following administration: 14 days.
- Frequency of observations and weighing: the general status of all animals has been daily monitored after 1, 3, 5 hours from the start of treatment and daily (5 days per week) for 14 days.
- Necropsy of survivors performed: yes
- Other examinations performed: clinical signs, body weight,organ weights, histopathology, other:
Clinical symptomatology: Every clinical symptom, including possible variations of somato-motory activity, was daily registered for each individual animal. Clinical observations included a general objective exam (G. O. E) above:
assessment of major organic functions;
assessment of the status of integumentary apparatus;
assessment of the status of mucosae;
assessment of somato-motory activity and of the sensory status.

Body weight: animals have been weighted before experiment, after 7 days and at the end of the experiment.

Post morterm: at the end of the observation period, animals have been sacrofoced and a post-morterm examination has been carried out.
Statistics:
no data

Applicant's summary and conclusion

Interpretation of results:
not classified
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
On the basis of obtained results, according to Official Journal of the European Union 1272/2008 (CLP) dated December 16th 2008 and OECD Guideline 402 of February 24th 1987, the test substance “tartaric acid” has a LD50 > 2000 mg/kg bw and can be considered non-classified.
Executive summary:

An acute dermal toxicity test was performed with the test substance “tartaric acid” in order to obtain the necessary data to evaluate its toxic effects. The test product has been administered with a dose of 2000mg/kg by topical application to a group of 10 rats (5 males and 5 females). During the study animals have been daily observed for 14 days to detect possible toxic symptoms. No toxic effect was found. On the basis of obtained result, according to official journal of the European Union 1272/2008 (CLP) dated December 16th2008 and OECD number 402 of February 24th1987, the test substance “tartaric acid” has a LD50 > 2000 mg/kg bw and can be considered non-classified.
