Acute Toxicity: dermal
Administrative data
- Endpoint:
- acute toxicity: dermal
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 06 June 1991 to 20 June 1991
- Reliability:

Results and discussion
Effect levels
- Key result
- Sex:
- male/female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Mortality:
- There were no deaths following a single dermal dose of the test item at 2000 mg/kg bodyweight.
- Clinical signs:
- There were no signs of systemic reaction. Incidence of enlarged submandibular lymp node was slighly higher but was consistent with normal background pathology.
- Body weight:
- All animals acheived anticipated body weight gains throughout the study.
- Gross pathology:
- No gross pathological findings were observed, autopsy revealed no macroscopic abnirmalities.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The results of an acute dermal toxicity study on the test item didt not produce any signs of toxicity and the acute lethal dermal dose LD50 to rats was found to be > 2000 mg/kg bodyweight.
- Executive summary:
An acute dermal toxicity study was performed using a method similar to OECD Guideline for Testing of Chemicals 402 "Acute Dermal Toxicity", and EEC Methods for the determination of toxcity, Directives 84/449/EEC (OJ No. L251, 19.9.84), Part B, Method B3. Acute Toxicity (Dermal). The application of of the test item at a single dose of 2000 mg/kg bw to the dorsal skin of 5 rats/sex under occlusive dressing for 24hours did not produce any signs of toxicity and it is concluded that the acute dermal dose LD50 to rats was found to be in excess of 2000 mg/kg bodyweight.
