GLP compliance:
no
Remarks:
Clinical study
Ethical approval:
not specified
Details on study design:
Volunteers of female and male sex from 20 to 65 years of age, with a normal skin , without any dermatological lesion on the experimental area shoul be included in the study
Exposure assessment:
measured
Details on exposure:
Single application of 25 µL of the studied test item, on the sacapular part of the back, maintained for 48 h in contact with the skin, with the help of an occlusive patch (Finn Chambers).
Results:
11 volunteers have been included. The average irritation index is 0
Conclusions:
The test item can be considered as non irritant after an application with the help of an occlusive patch for 48 h on 11 volunteers.
Executive summary:

In a single patch test, 11 volunteers (men and women) from 20 to 65 years of age, with a normal skin, without any dermatological lesion on the experimental area, have been included in the study. Single application of 25µL of the test item, on the sacapular part of the back, maintained for 48 h in contact with the skin, with the help of an occlusive patch (Finn Chambers).

11 volunteers have been included and were analyzed. The average irritation index is 0.

Under the conditions employed in this study, test item was considered as non-irritant.
