Results and discussion

Results of examinations:

This study was initiated with 56 subjects. One subject discontinued study participation for reasons unrelated to the test material. A total of 55 subjects completed the study.
Individual dermal scores recorded during the Induction and Challenge Phase appear in table 1 (report attached)
Based on the test population of 55 subjects and under the conditions of this study, the test material identified as Fatty acids, C5-9, hexaesters with dipentaerythritol did not demonstrate a potential for eliciting dermal irritation or sensitization

Applicant's summary and conclusion

Conclusions:

Based on the test population of 55 subjects and under the conditions of this study, the test material identified as Fatty acids, C5-9, hexaesters with dipentaerythritol did not demonstrate a potential for eliciting dermal irritation or sensitization

Executive summary:

To determine the irritation and/or sensitization potential of the test article after repeated application under occlusive patch test conditions to the skin of human subjects (non-exclusive panel).

Fifty-six (56) subjects, 6 males and 50 females, ranging in age from 18 to 67 years were impaneled for this test.

The 9 Repeated Insult (semi-occlusive) Patch Test (9 RIPT) was conducted.

Based on the test population of 55 subjects and under the conditions of this study, the test material identified as Fatty acids, C5-9, hexaesters with dipentaerythritol did not demonstrate a potential for eliciting dermal irritation or sensitization
