Details on study design:
In a acute dermal toxicity study (Hazleton Laboratories, Virginia, 1972) 2 New Zealand White rabbits were dermally exposed to 2,4-dichlorotoluene (pure).The substance was applied to the skin of the abdomen. The test site was intact or scarified.
Doses: 316 – 10 000 mg/kg bw.
Period of exposure: 24 hours
Observation period after exposure: 7 days.
No animals died during the test.
No signs of systemic toxicity were observed.
The skin showed slight to moderate erythema, oedemas, temporary bleaching and desquamation over the treated area.
The value of the dermal toxicity was determined to be > 10 000 mg/kg bw.
