Trial Purpose:

To test the efficacy of Green Mountain Ammenitie's foaming hand soap against other hand soaps.

Date Run:

09/14/2023

Experiment Procedure:

The soil used consisted of 5 grams of Synthetic carpet soil AATCC Test Method 122, 20 ml tap water. The water and soil were mixed together to make a paste. A quarter size amount of soil was applied to a subject's hand.  Both hands were then rubbed together to distribute soil to both hands.

Using tap water hands were wetted and apply two pumps of supplied hand soap was applied. The comparative product was used in the same weight range of the supplied product. This was about a half of one full pump. Hands were rubbed together with soap and water for 20 seconds followed by rinsing hands in tap water for 20 seconds. Final step was to wipe or blot hands dry for 20 seconds.

During the evaluation observations were made for cleaning and rinsing. Observations were ranked using the following guidelines:
