Applicant's summary and conclusion
- Executive summary:
In this acute dermal toxicity study Wistar rats were dermally exposed to p-chlorobenzyl chloride in polyethylen glycol at doses of 1000 mg/kg bw (5/sex), 1100 mg/kg bw (5/sex), 1200 mg/kg bw (5/sex), 1400 mg/kg bw (5/sex), 1500 mg/kg bw (5/sex) and 1600 mg/kg bw (5/sex).
Animals then were observed for 14 days.
Necropsy of dead and of surviving animals showed no signs of pathological changes.
The LD 50 value was established to be 1287 mg/kg bw for both sexes.
