Primary Outcome Measures:
  • Number of participants with positive reactions, number of positive reactions. [ Time Frame: One week ]

    Erythema, edema, blisters, pustules or erosions on the skin in the patch area will be considered a positive response.

    If the skin is normal after the patch removal, it means that contact with the material do not cause allergy or irritation.

Secondary Outcome Measures:
  • Number of irritant versus allergic reactions, as determined by confocal microscopy. [ Time Frame: On the spot ]
    In case of a positive reaction, it will be examined by confocal microscopy, by a specialist, to determine whether the reaction is irritant or allergic in nature.

Estimated Enrollment: 100
Study Start Date: June 2013
Estimated Study Completion Date: September 2013
Estimated Primary Completion Date: August 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
patch tests on healthy skin Other: patch tests on healthy skin
Patches will be placed on healthy skin.

Detailed Description:

Volunteers will be seen on Day #0 and the study purpose will be explained. Each volunteer will be interviewed to determine if he/she has any exclusion criteria.

If there is no contraindication, and agreement is achieved,consent forms will be signed.

Volunteers will be examined by a lactic acid test to determine if he/she has normal or sensitive skin. In this test, a Finn's cell (plastic cell, size 1*1 cm) with lactic acid (50 microliter, 10%w/v) will be placed on the volunteer's cheek for ten minutes. The volunteer will be defined as "sensitive" or "normal" according to the degree of discomfort they report.

Patch-tests will be performed in the standard method. The materials to be tested will be placed in Finn's cells and attached to the participants healthy skin's back by a plaster (Micropore).The chambers will be left on the skin for 48 hours. The test will be read by a specialist one hour after chambers' removal and 48 hours afterwards. Any erythema,edema, blisters, pustules or erosions on the skin in the patch area will be considered a positive response, and will be evaluated by clinical tools as being of the irritant or the allergic type. in case of uncertainty we may use a confocal microscope for in vivo diagnosis.

Ingredients: appropriate concentrations and solvents of the test materials will be prepared according to accepted standards (refer to: Anton C. De Groot: Patch Testing, 3ed Edition, Wapserveen, The Netherlands, 2009).Leave on products will be tested 'as is'. Rinse off products will be diluted to 5% and 0.5%.

If the skin stays normal after the patch removal, it means that contact with the material did not cause allergy or irritation.
