- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Under the conditions of the present study, none of ten animals of the treatment group showed a positive skin response after the challenge procedure.
Thus, the percentage of animals reacting positive is 0% ( below the threshold of 30 %).
Based on the results of this study the test item showed no evidence for sensitizing properties. - Executive summary:
Testing for sensitizing properties of the test item was performed in female guinea pigs according to the method of MAGNUSSON & KLIGMAN.
Intradermal induction was performed using 1 % of the test item in sesame oil. Dermal induction and challenge treatment were carried out with 25%
of the test item in sesame oil.
The validity of the test system is confirmed by the periodically conducted positive control test using alpha-hexyl cinnamic aldehyde for the maximization test
Based on the results of this study the test item sh
owed no evidence for sensitizing properties.
