- Executive summary:
A test for skin compatibility was performed to assess the dermal irritation potential of the test chemical. The test was performed according to the "1500.41 in Federal Register 38, No. 917, 27, 9, 173, P 27019" and FDA Guidelines.
6 SPF-albino-Himalayan rabbit strain Hoe: HIMK (SPFWiga) were used for the study. The flank skin of 6 rabbits was depilated with an electric hair trimmer on two adjacent spots on a 3 × 3 cm area respectively. Either one of the clipped skin spots was additionally scarified using a scrape cutter. On 2.5 * 2.5 cm coarse lids of surgical gauze, 500 mg of the powdered dye was applied and glued to the prepared skin areas by means of an adhesive strip. The patches were covered by an infectious, impermeable, 6-8 cm wide PVC foil and then wrapped in an elastic permanent bandage. The exposure time was 24 hours.The dermal reactions were observed and scored after removal of the patches (24 hours) and 48 and 72 hours after the start of the test.
The dye was tolerated without irritation by all rabbits (index = 0). Under the test conditions described under FDA guidelines in the patch test, the test chemical can be assessed as not irritating to skin.
