Applicant's summary and conclusion
- Interpretation of results:
- other: CLP/EU GHS criteria not met, no classification required according to Regulation (EC) No 1272/2008
- Conclusions:
- No skin irritating effects of the test item were recorded after 48h.
- Executive summary:
The test was based on the descriptions for skin irritation, EEC Commission Directive of 25 April 1984 (84/449/EEC), page 106 to 108 of document L251. 0.5 mL aliquots were applied over an areea of 6 cm² on the dorsal skin, clipped free of fur, of four albino rabbits. The material was held in contact with the skin under a semi-occlusice dressing for a four hour period after which the patches were removed. Skin reaction to the materials was assessed after 1, 24, 48 and 72 h and 7 days. Irritation of the skin was only apparent after 1 and 24 h, after 48 h no effect was recorded.
