Applicant's summary and conclusion
- Interpretation of results:
- not sensitising
- Remarks:
- Migrated information
- Conclusions:
- In view of the results, under the experimental conditions described, the test product must no be classified in accordance with the criteria for classification, packaging and labelling of dangerous substances of the E.E.C Directives 67/548, 2001/59 and 99/45. In accordance with the Globally Harmonized System (Regulation EC N° 1272/2008), the test product must not be classified in category 1..
- Executive summary:
The aim of the study was to evaluate the possible allergenic activity of the test substance after intradermic injection and topical administration in guinea pigs. After induction (intradermic injection at 3.125% and topical application at 50 and 100%) of 11 Guinea Pigs of treated group with the test product and a 10-day rest phase, the challenge phase, under occlusive dressing for 24 hours, consisted to a single topical application of the test product diluted at 50% and at 100%. The experimental protocol was established according the O.E.C.D. guideline n°406 dated July 17th, 1992 and the method B.6 of the council regulation N° 440/2008.
No macroscopic cutaneous reactions attributable to allergy was recorded during the examination following the removal of the occlusive dressing (challenge phase) from the animals of the treated group with the test item. It was recorded a slight erythema in 9% (1/11) of the animals from the treated group, 24 and 48 hours after the challenge phase, on the treated area at 100%. No cutaneous intolerance reaction was recorded in animals from the negative control group. In conclusion, in view of these results, under these experimental conditions, the test substance needs not be classified, in accordance with the criteria for classification, packaging and labelling of dangerous substances and preparations of the E.E.C. Directives 67/548, 2001/59 and 99/45. No symbol and risk phrase are required. In accordance with the Globally Harmonized System (COM(2007)355 final), the test item must not be classified in category 1. No signal word and hazard statement are required.
