Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Remarks:
- Criteria used for interpretation of results: EU
- Conclusions:
- Under the conditions of the test, application of the test material resulted in no irritation in any of the rabbits, and had no effect on body weights.
- Executive summary:
The acute dermal irritation potential of the test material was determined in a GLP study conducted in accordance with the standardised guidelines OECD 404, EPA OPPTS 870.2500, EU Method B.4, and Japan MAFF Primary Dermal Irritation Study, 1985.
Aliquots of 0.5 g of the neat test material, moistened with 0.7 mL of 0.5 % methylcellulose, were applied for four hours to the intact skin on the back of three New Zealand White rabbits.
Under the conditions of the test, application of the test material resulted in no irritation in any of the rabbits, and had no effect on body weights.
