Results and discussion
- Results of examinations:
- Visible skin changes signifying reaction to injury were observed in 1 out 200 human subjects during the series of application or following the challenge application. On re-challenge, the component found to be responsible was Irganol Yellow 4Glass 125 % (FAT 21015).
Any other information on results incl. tables
None
Applicant's summary and conclusion
- Conclusions:
- FAT 21015 is considered to be neither a primary irritant nor a sensitizer.
- Executive summary:
A key study was performed in humans to determine skin irritation potential of FAT 21015. Visible skin changes signifying reaction to injury were observed in 1 out of 200 subjects during the series of application or following the challenge application. In re-challenge, the component found to be responsible was FAT 21015. Despite the reactions elicited by the component and/or the components contained therein, it is the opinion of the investigator that the results must be interpreted as indicative of having potential rather than obligatory irritating capabilities because of unusual conditions of the test.
