-Semi-occlusive hypoallergenic tape;
-0.9% sterile physiological solution (NaCl 0.9%);
-Gloves, masks and caps;
-Surgical marker;
-Cotton swab;
-Scale
-Micropipette;
-Heating plate;
-Beaker;
-Dropper bottle;
-Transparent bottle.
Test Site
The product was applied to the study subjects back (scapular area).
Population Size
This study was conducted with 70 approved subjects so it could be completed with at least 50 responses.
Procedures
At first the study subjects were assessed by a dermatologist in order to verify the inclusion and exclusion criteria.
The patch test methodology (KLIGMAN & WOODING, 1967), also known as contact test or epicutaneous test, was used.
The product (0.05g/cm²) was distributed on the duly identified patch test filter paper disc and the 0.9% sterile physiological solution, used as control, was distributed on another duly identified disc.
The patch test containing both the test-product and control was then attached to the scapular area of the right or left back of the subjects.
Induction Period: the applications were performed three times a week, for three consecutive weeks, remaining in contact with the skin for 48 hours during the week and for 72 hours during weekends.
Rest Period: There was a rest period of at least 10 days following the induction period, when no patches were applied.
Challenge period: After the rest period, a patch with the test product and control was applied to the right or left back of the subjects on a virgin area, that is, where no patches had been applied before.
The patch was removed by the investigators after approximately 48 hours of contact with the skin.
The assessments (readings) were performed approximately 30 minutes (48h reading) and 24 hours (72h reading) after patch test removal.
The subjects were assessed at the end of the study by a dermatologist and supervised all along the study.
Assessment of Clinical Signs (Readings)
In case any subject presented any clinical sign during the readings, the assessment scale published by the International Contact Dermatitis Research Group - ICDRG (FISHER, 1995) would be used.
Results and discussion
- Results of examinations:
- Adherence to the Study
A total of 58 subjects completed the study.
A total of 09 subjects withdrew from the study due to personal reasons unrelated to the test product (025, 026, 045, 057, 079, 086, 087, 089 and 090).
Subjects 007, 013 and 014 presented irritation resulting from the exposure of the semi-occlusive tape (sticking plaster), probably due to individual pre-disposition, and for that reason the applications were discontinued and their data were not used in the study.
Dermatological Clinical Assessment
During the study, no subjects presented any clinical signs in the test product application site.
No subjects presented clinical signs in the control site.

Applicant's summary and conclusion
- Conclusions:
- According to the methodology used to assess the skin sensitization potential of the product PX-200, submitted by the company DAIHACHI CHEMICAL INDUSTRY CO.,LTD. it could be concluded that:
-During the study, no subjects presented skin clinical signs related to the product.
-The product did not induce a skin sensitization process in the study group.
-The product was considered safe under the study conditions. - Executive summary:
STUDY OBJECTIVE
To prove the absence of the skin sensitization potential of a product applied to the skin, under maximized conditions, with controlled product amount and application site, supervised by a dermatologist.
METHODOLOGY
Both the test-product and control were applied to patch test filter paper discs and then applied to the right or left back (scapular area) of the study subjects. The applications were performed on Mondays, Wednesdays and Fridays, during 3 consecutive weeks. Forty-eight hours (48h) after the application, the patch test was removed by trained technicians and, approximately 30 minutes after the patch test removal, the site was assessed in order to check the presence of possible clinical signs.
After this period (induction) there was a, minimum, 10 day-period when no patch was applied to the study subjects' back (rest period).
Then, the challenge period started. A single application of the patch test was performed, followed by readings after 48h and 72h.
The study subjects were assessed by a dermatologist at the start and at the end of the study and supervised all along the study.
STUDY LENGTH
6 weeks.
FREQUENCY OF APPLICATION
9 applications on the 3 first weeks (induction period).
1 application on the last week (challenge period).
APPLICATION SITE
Back (Scapular area).
NUMBER OF SUBJECTS
