- METHODOLGY.
The upper back between the scapulae served as the treatment area. Approximately 0.2 g of the test material (10% in neutral oil), or an amount sufficient to cover the contact surface was applied to the 3/4" x 3.4 " absorbent pad portion of an adhesive dressing and allowed to volatilize for several minutes. When secured to the appropriate treatment site, this dressing formed an occlusive patch.
The test material remained in contact with the skin for a total of forty eight hours. This site was then evaluated for gross changes. Absence of any visible skin change was assigned a zero value. The test site was reevaluated at seventy-two hours (the evaluation criteria used in this study can be see under "Any other information on materials and methods incl tables" below). - Statistical methods:
- No data
Results and discussion
- Results:
- Observations remained negative throughout the test interval.
- Confounding factors:
- No data
- Strengths and weaknesses:
- No data
Applicant's summary and conclusion
- Conclusions:
- Under the conditions of this study, the test material SymSitive® 1609 pur (10% in neutral oil) did not indicate a potential for dermal irritation.
