Brief Summary

The purpose of this study is to evaluate the effectiveness of whole-natural hand-wash formulations in bacterial removal and to estimate the relative mildness of the formulations.

Detailed Description

Hand washing with soap and water is one of the main ways to prevent the spread of diseases in general and specifically, the spread of hospital-acquired diseases. Mother's Choice Company develops natural products and technologies which include hand-wash soap. The purpose of this project is developing a whole-natural hand wash soap including no harmful ingredients which will succeed to remove at least 99.9% (3 log reduction) of the hand transient microbiota. In addition, the soap will be mild enough to allow the use of dozens times a day. The procedure for evaluating soap effectiveness in bacterial removal will include in general: bacterial application on hands, hand washing with the tested soap, sampling of hands before and after hand washing. The procedure for soap mildness estimation will include exposure of specific area of the arm or the back skin to the soap and following up and grading the reaction of the skin.
