Applicant's summary and conclusion
- Interpretation of results:
- other: Skin Corr. 1B
- Remarks:
- according to the classification criteria outlined in Annex I and according to Annex VI of 1272/2008/EC (CLP).
- Conclusions:
- Tosylchloramide sodium, trihydrate resulted in an average overall irritation score of 0.7 ) when applied to the intact rabbit skin. However, according to the clinical judgement of the treated skin in two animals (corrosion). The substance is classified in catergory Skin Corr. 1B (H314: Causes severe skin burns and eye damage) according to the classification criteria outlined in Annex I and according to Annex VI of 1272/2008/EC (CLP).
- Executive summary:
The purpose of this study was to assess the possible irritation or corrosion potential of Tosylchloramide sodium, trihydrate when a single dose was placed on the skin of rabbits. This study was carried out in accordance with OECD Guideline No. 404, "Acute Dermal Irritation/Corrosion and EEC Directive 84/449/EEC, Part B.4, "Acute Toxicity - Skin Irritation". Tosylchloramide sodium, trihydrate was applied on the shaved skin of six animals, using semi-occlusive dressings for 4 hours, followed by six (seven) observations at approximately 1, 24, 48 and 72 hours and 7 and 14 days (and 21 days for three animals only) after removal of the dressings and the remaining test substance. Under the conditions of this study, Tosylchloramide sodium, trihydrate resulted in no skin irritation in two animals, very s light oedema and/or very slight erythema in two other animals and eschar formation and slight oedema in the remaining two animals. The eschar formation and oedema noted in two animals were disappeared within 15 days in one of the two animals. Both animals showed scar tissue on each last observation day. The slight skin irritation noted in two animals was reversible within 24 hours, while the severe skin irritation in the other two animals was reversible within 15 days in one of these animals and not reversible within the study period (22 days) in the second animal. In the area of application, yellow staining of the treated skin by the test substance was observed in four of the six animals. Corrosive effects occurred on the skin in two of the six rabbits. No signs of systemic intoxication were observed during the study period. Tosylchloramide sodium, trihydrate resulted in an average overall irritation score of 0.7 ) when applied to the intact rabbit skin.
However, according to the clinical judgement of the treated skin in two animals (corrosion). The substance is classified in catergory Skin Corr. 1B (H314: Causes severe skin burns and eye damage) according to the classification criteria outlined in Annex I and according to Annex VI of 1272/2008/EC (CLP).
