- Interpretation of results:
- not sensitising
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- In view of these results, under these experimental conditions, the test item N,N'-hexane-1,6-
diylbis(hexahydro-2-oxo-1H-azepine-1-carboxamide) needs not to 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 needs not to
be classified in category 1. No signal word and hazard statement are required. - Executive summary:
The aim of the study was to evaluate the possible allergenic activity ofthe test item N,N'-hexane-l,6 -
diylhis(hexahydro-2 -oxo-1H-azepine-l-carboxamide) after intradermic injection and topical
administration in guinea pigs.
After induction (intradermic injection at 10% and topical application at 50%) of 10 Guinea Pigs of
treated group with the test item N,N'-hexane-l,6 -diylbis(hexahydro-2 -oxo-1H-azepine-1 -carboxamide)
and a 10 -day rest phase, the challenge phase, under occlusive dressing for 24 hours,
consisted to a single topical application of the test item diluted at 50% and at 25% in liquid paraffin.
The experimental protocol was established according the OECD guideline No. 406 dated July 17th,
1992 and the method B.6 of the EEC No. 96/54 dated July 30th,1996.
It was recorded a slight to moderate erythema, in respectively 20% (2/10) and 10% (1 /10) of the
animals from the treated group, 24 and 48 hours after the challenge phase, on the treated areas at 50%
and 25%. These reactions were totally reversible at the reading time 72 hours.
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 item N,N'hexane-
l,6 -diylbis(hexahydro-2 -oxo-1H-azepine-1 -carboxamide) needs not to be classified, in
accordance wilh the criteria for classification, packaging and labelling of dangerous substances and
preparations of the E.E.C Directives 67/548, 2001159 and 99/45. No symbol and risk phrase are
required.
In accordance with the Globally Harmonized System (COM(2007)355 final), the test item needs not to
be classified in category I. No signal word and hazard statement are required.
