Results and discussion
- Results:
- NO. OF PERSONS WITH/OUT REACTIONS COMPARED TO STUDY POPULATION
- Number of subjects with positive reactions: 0/50
- Number of subjects with negative reactions: 50/50
- Number of subjects with equivocal reactions: 0/50
- Number of subjects with irritating reactions: 0/50
Applicant's summary and conclusion
- Conclusions:
- At the end of the 72 h exposure period in the initial application there were no reactions on the skin of any of the subjects. This shows that the chemical is not a primary skin irritant.
At the end of the 72 h exposure period in the challenging application there were no reactions on the skin of any of the subjects. There were no delayed reactions after the first and second series of patches. This indicates that the chemical is not a sensitizer.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
