Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The test material did not meet the criteria for classification as irritant or corrosive according to EU labelling regulations Commission Directive 2001/59/EC. No symbol and risk phrase are required.
- Executive summary:
A study was performed to assess the initation of the test material to the skin of the New Zealand White rabbit (SPL Standard Test Method 540.10). The method followed OECD Guidelines for Testing of Chemicals (24 April2002) No. 404 "Acute Dermal Initation/Corrosion" and Method B4 of Commission Directive 2004/73/EC (which constitutes Annex V of Council Directive 671548/EEC). The test material did not meet the criteria for classification as irritant or corrosive according to EU labelling regulations Commission Directive 2001/59/EC. No symbol and risk phrase are required.
