TEST MATERIAL
- Amount(s) applied (volume or weight with unit): 2000 mg/kg body weight

- Males - 5
Females - 5 - Control animals:
- no
- Details on study design:
- - Duration of observation period following administration: 14 days
- Frequency of observations and weighing: Observations: Several times on the day of application then twice daily (once at weekends & bank holidays). Weighing: Directly before administration, after one week and at the end of the 14 day observation period.
- Necropsy of survivors performed: yes - Statistics:
- Taking into consideration available data, the dosages are selected in such a way that graded lethality rates are obtained, which allow calculation or at least an estimate of the LD50.
Sufficient characterisation of acute dermal toxicity is reached as a rule, even if no substance-related lethality occurs at a dosage of 2000 mg/kg body weight.
The dosages are given in mg/kg body weight.
The following dosage was administered:
2000 mg/kg body weight
The calculation of the amount of test substance to be administrated was done taking into account a content of 65%.
Calculation of the Median Lethal Dose (LD50)
If calculation of the median lethal dose (LD50) is possible, it is done according to Spearman-Karher. The algorithm was adopted from SACHS, L. (Angewandte Statistik, 6.Auf1. 1984 , 178).
Should there be value pairs with a mortality of 0% and 100%, the geometric mean of the corresponding dosages is regarded as the "approximate LD50 value".
If only one dose group is used, the LD50 is estimated.
Results and discussion
- Preliminary study:
- Not applicable.
Effect levels
- Sex:
- male/female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Mortality:
- No animal died during the 14-day observation period.
- Clinical signs:
- other: No signs of systemic poisoning were observed after single application of 2000 mg/kg body weight. After the 21-hour exposure the skin in the area of the application site showed a blue discoloration in all rats. This coloration persisted until the 9th day
- Gross pathology:
- None of the animals sacrificed at the end of the 14-day observation period showed any noticeable gross pathological findings.
- Other findings:
- None
Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- Based on the present investigations, the test substance is therefore to be regarded as relatively non-toxic after acute dermal exposure.
LD50 > 2000 mg/kg body weight - Executive summary:
Study conducted to recent EU test guidance 92/69/EEC part B3 and OECD test guideline 402 in compliance with GLP.
Based on the study the test substance is to be regarded as relatively non-toxic after acute dermal exposure. The test substance is not classified.
LD50 > 2000 mg/kg body weight.
