Executive summary:

In an acute dermal toxicity study according to EPA 40 CFR, Par. 158.50 & 158.135, Subdivision F, Section 81-2, New Zealand White rabbits (5/sex) were dermally exposed to Reaction product of lauryl-PDA/lauryl-DETA with chloroacetic acid (22.5% a.i) for 24 hours at a single dose of 2000 mg/kg bw in terms of test material (corresponding to 450 mg a.i./kg bw). Animals then were observed for 14 days.

2/5 females died during the observation period. 5/8 surviving animals showed weight loss on day 14.

The test item was corrosive to the skin (edema and erythema scores of 4 after 24 and 48 h). The skin sites were severely burned and discoloured black. The skin was thickened and stiff.
