Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Irritation scored by Erythemal Scoring Scale | 8 weeks | Basic Score and Description: 0 - No visible reaction. 0.5 - Doubtful or negligible erythema reaction. 1.0 - Mild or just perceptible macular erythema reaction in a speckled/follicular, patchy or confluent pattern (slight pinking). 2.0 - Moderate erythema reaction in a confluent pattern (definite redness). 3.0 - Strong or brisk erythema reaction that may spread beyond the test site. If a subject develops a positive reaction (a score value of 1.5) to the test material or shows signs of irritation after patch applications, further patching on those individuals are stopped. In order to qualify for the claim of a reduced sensitization potential, all 200 individuals completing the study should exhibit a score value of no more than 1.5 based on the scoring criteria. |
