Materials and methods

Test guideline
Qualifier:
no guideline followed
Principles of method if other than guideline:
3 male and 3 female animals were subjected to a limit test. The test substance was applied to a 2.5 x 2.5 cm application site for 20 h under occlusive conditions. The skin was either intact or abraded. After the application time, the skin was washed with water which may have contained a mild detergent. Animals were observed for 8 days and skin changes were observed on working days. Findings were recorded and graded as described in OECD test guideline 404.
GLP compliance:
no
Test type:
standard acute method
Limit test:
yes

Results and discussion

Effect levels
Key result
Sex:
male/female
Dose descriptor:
LD50
Effect level:
> 2 000 mg/kg bw
Mortality:
no deaths occurred
Clinical signs:
other: no signs of general toxicity could be observed;
Gross pathology:
Skin necrosis pathologically confined
Other findings:
Necrosis were observed at the site of applicatation on the day following substance application.

Any other information on results incl. tables

The skin irritation properties of the test substance seem to be the limiting factor of acute dermal toxicity. No further clinical signs of toxicity were observed.
