Executive summary:

The dermal irritation potential of the test article was evaluated in New Zealand White rabbits (3 female). The study was conducted according to OECD GLP (1999). The test method was based on OECD 404 (1992), EEC Method B.4. (1992) and US EPA OPPTS 870.2500 (1998). Prior to exposure (24 hours) the hair on the left flank of each animal (25 mm2) was clipped. Each animal was treated with 0.5 mL of the test article dosed on a 2.5 cm2 cellulose patch, placed on a piece of surgical plaster and covered with a semi-occlusive bandage. The patch was left in place for 4 hours, after which the remaining test article was removed from the exposure site with warm water. The skin was examined for erythema and edema at 1, 24, 48, and 72 hours. Animals were observed daily for clinical signs and mortality. No abnormal clinical signs were observed in any animals during the study period. No erythema or edema was observed in any animal at any time period during the study. Based on the results of the study, the test article is not irritating to skin.
