Applicant's summary and conclusion
- Interpretation of results:
- not irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The test material did not meet the criteria for classification as irritant or corrosive according to EU or GHS labelling regulations. No symbol or risk phrase are required.
- Executive summary:
A study was performed to assess the irritancy potential of the test material to the skin of the New Zealand White rabbit. The method used followed the recommendations of the OECD Guidelines for Testing of Chemicals No. 404 "Acute Dermal Irritation/Corrosion" (adopted 17 July 1992) and Method B4 of Commission Directive 92/69/EEC (which constitutes Annex V of Council Directive 67/548/EEC).
The results may be used as a basis for classification and labelling under Annex VI of Council Directive 67/548/EEC (as adap[ted to technical progress by Commission Directive 93/21/EEC) relating to the classification, packaging and labelling of dangerous substances.
A single 4 -hour, semi-occluded application of the test material to the intact skin of three rabbits produced no evidence of skin irritation. No corrosive effects were noted.
3 -minute and 1 -hour semi-occluded applications of the test material to the intact skin of one rabbit produced no corrosive effects.
The test material did not meet the criteria for classification as irritant or corrosive according to EU or GHS labelling regulations. No symbol or risk phrase are required.
