Details on study design:
TYPE OF TEST USED: Human patch test

ADMINISTRATION
- Type of application: occlusive
- Description of patch: The patch sites were pre-treated for 24 hours with 5 % aqueous sodium lauryl sulfate under occlusion. The challenge sites were read on removal of the patch and 24 hours thereafter.
- Vehicle: Sodium lauryl sulfate

Results and discussion

Results of examinations:
There were no instances of contact-sensitization. It is unlikely that the test material would present a danger of contact-sensitization in normal, intended use.

Applicant's summary and conclusion

Conclusions:
There were no instances of contact-sensitization. It is unlikely that the test material would present a danger of contact-sensitization in normal, intended use.
Executive summary:

A human maximization test was conducted to determine the contact-sensitizing potential of the test item. 25 healthy adult volunteers were used in a maximization test. In the main test the test item was applied under occlusion to the same sites on the volar forearms of all subjects for five alternate-day 48 hour periods. The patch sites were pre-treated for 24 hours with 5 % aqueous sodium lauryl sulfate under occlusion. The challenge sites were read on removal of the patch and 24 hours thereafter. No instances of contact-sensitization from any material on the maximization test were found.
