### esperimental protocol described below.
3.1. INCLUDEA 5[IBSECTS 8 females and 

### 3 males were selected. They were from 21 to 42 years o1d (mean :.26). i111 subjects were detei

- mined to be frce oz" any vi.sible ski ❑ disease in the area to be patched. tiol)ody was under treatmanr„ whicn could interfere with the results of the study or which 

### could induce a risk for the volunteer. Subjects declared as "elegible" had signed an informeG consent statement. These informed consent statements are stored in special premises of BIOGIR S.A.

3.2. TBBATMENTS The 

### trial involved the appiicata:on of the test product under occlusice conditions (patch cest). We used aluminum cups of 

### 8 mm in diaareter and of 20 pl in volume. Each cup represented about a50 mm 2 area_ ?`hey were affixed by two on an adhesive tape. The product was studiec9 20 t diluted. The salution was placed on a speczal absorbant paper disc, laid down in the alumznum cup. The patch caas applied to the ?eft upper bac:-c which 

### had not received any previous treatment. , .1 2'; solution of sodium laucyl sul?s,te was used as positive cor.trol and was applicd che same :aa,v on a diffNrent skin area. The 

### second cup containing distiiled seatcr .aas used as negati=.e control.

### 3.3. ASSfiSSMENT OF IRRITATIVE Rfi,4GTI0NS

24 hours ai'ter tie application, the patch was removed and the skin was examinated C(ir any dermal response 30 minutes later. The parameters Scored were :

erythema dryness oedema . wrinkling vesicles glazing Scc,7ring of each parameter was in accordance wiLh the scale in nppendix. .a second reading was performed 24 hcurs iater in order to assess the reversibility ot' lesions or to note any zaossible delayed reactiozr.

4. RESULTS They are given in Tables I ta 3 in appendix. The table 1 gis;es the scores obtained with the positive control and the table 2 those obtained wita the negative control (distilied water). Table 3 gives the scores obtained £or the test product.
