Constituent 1
Method
- Type of population:
- general
- Ethical approval:
- not specified
- Subjects:
- - 25 adult volunteers
- Route of administration:
- dermal
- 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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
