Brief summary
This study evaluates reduction of resident flora produced by the test product within a defined prepped area of skin.
Detailed description
Three different sample sites within a defined prepped area of skin were collected to determine whether reductions in resident flora produced by the test product are consistent.

| Measure | Time frame | Description |
|---|---|---|
| Comparison of Log Change of Skin Flora Relative to Pre-treatment (Baseline) in Each of 3 Sampling Sites at a Defined Post-treatment Sampling Time. | Post-treatment sampling randomized as 10-minute or 13-minute post-product application | The primary measure of efficacy is change in skin flora log10 CFU/cm\^2 in each of the skin sampling sites relative to baseline skin flora log10 CFU/cm\^2. Baseline samples must satisfy the greater than or equal to 3.0 in each of the sampling sites, to be used for data analysis. |

| Safety Outcome Evaluated by Skin Irritation Assessment | Assessed pre-treatment (baseline) and post-treatment (10 or 13 minutes) | Skin irritation (dryness, edema, erythema, rash) assessed on the test sites using a 0-3 rating scale: 0 = no reaction, 1 = mild reaction, 2 = moderate reaction, 3 = severe reaction. |

Outcome results
Comparison of Log Change of Skin Flora Relative to Pre-treatment (Baseline) in Each of 3 Sampling Sites at a Defined Post-treatment Sampling Time.
The primary measure of efficacy is change in skin flora log10 CFU/cm\^2 in each of the skin sampling sites relative to baseline skin flora log10 CFU/cm\^2. Baseline samples must satisfy the greater than or equal to 3.0 in each of the sampling sites, to be used for data analysis.
Time frame: Post-treatment sampling randomized as 10-minute or 13-minute post-product application
Population: The primary analysis data set used a Modified Intent to Treat population: Subjects were excluded who did not meet the baseline requirement of greater than or equal to 3.0 log10 CFU/cm2 in all three sampling sites on the treatment site. The sampling time for efficacy evaluation was 10 minutes or 13 minutes post-product application as per the randomization schedule.

Safety Outcome Evaluated by Skin Irritation Assessment
Skin irritation (dryness, edema, erythema, rash) assessed on the test sites using a 0-3 rating scale: 0 = no reaction, 1 = mild reaction, 2 = moderate reaction, 3 = severe reaction.
Time frame: Assessed pre-treatment (baseline) and post-treatment (10 or 13 minutes)
Population: All treated subjects were considered evaluable for safety. Safety assessments were based on evaluations for skin reactions at the test sites.
