Materials and methods

Test guideline
Qualifier:
no guideline followed
Principles of method if other than guideline:
ATEC was evaluated in 59 human subject panelists (males and females) in the repeated insult patch test of Draize. The test substance was found not to induce dermal irritation or contact sensitization. For this test, each of the 59 panelists received a test patch (20x20 cm) moistened with 0.4 mL of ATEC to the upper arms 3 times a week for 3 weeks. Patches were secured in place for 24 hours before removal. Duplicate challenges were made 2 weeks after the final serial applications, 1 set of patches to original sites and 1 set to adjacent sites. Patch sites were scored prior to patch applications and scored at 48 and 96 hours after applications.
