Abstract

PURPOSE:

This study was designed to assess the ability of 2 skin cleaning procedures to remove transient microbial flora from the skin.

DESIGN:

The study is a direct comparison of 2 washing procedures: soap and water washing versus cleansing with a no-rinse cleanser.

SETTING AND SUBJECTS:

The trial was performed at the research facilities of the Department of Clinical Bacteriology at the University of Göteborg. Forty-five healthy adult volunteers were recruited to participate in the study.

METHODS:

A solution of test bacteria, either Escherichia coli or Staphylococcus aureus, was applied to both forearms of the test subject. After a 15-minute incubation period, one arm was cleaned using soap and water and the other arm was cleaned with no-rinse cleanser. Both the arms were dried with a disposable cloth. The amount of residual bacteria on the skin was assessed using contact agar plates.

RESULTS:

Both methods of cleaning resulted in 4-to 5-fold log reductions in bacterial count. The number of residual bacteria after both procedures ranged from 1 to 4 colony-forming units/cm after washing. The amount of residual bacteria was comparable for both washing procedures.

CONCLUSIONS:

Both washing procedures resulted in a low level of residual bacteria on the skin. No-rinse cleansers can be safely used as an alternative to soap and water washing of fragile skin.
