Applicant's summary and conclusion
- Conclusions:
- The No Observed Effect Level (NOEL) for systemic effects is 225 mg/kg bw/day for effects on the skin the NOEL is 25 mg/kg bw/day.
- Executive summary:
A sub acute 21 -day dermal toxicity study was performed at TNO, The Netherlands with albino rabbits. Repeated dermal application of Tosylchloramide sodium, trihydrate at a dose of 225 mg/kg bw/day resulted in distinct skin lesions consiting of scaliness, coriaceousness, haemorrhages, fissuring and sloughing. A slight scaliness and very slight coriaceousness of the exposed skin was seen in the animals of the group treated with 75 mg/kg bw/day. No distinct skin lesions were observed in the lowest dose group 25 mg/kg bw/day. All experimental animals showed a yellowish discolouration of the fur as a result of the application of Tosylchloramide sodium, trihydrate. General appearmce and behaviour, growth, food and water consumption, blood and urine composition, and organ weights were not adversely affected by the repeated dermal application Tosylchloramide sodium, trihydrate. Histologically, distinct changes of the treated skin were found in the two highest dose groups.
The No Observed Effect Level (NOEL) for systemic effects is 225 mg/kg bw/day for effects on the skin the NOEL is 25 mg/kg bw/day.
