To evaluate the face and body wash performance for cleanliness, lathering, and dryness under GS 41 Hand Washing test method.
Three testers were used to evaluate the supplied products’ performance. A preliminary review of the tester’s hands was conducted before soiling their hands with GS 41 Hand Washing test soil. 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 the soil to both hands for 20 seconds. The dirtied hands were considered the baseline for the dirtiest cleanliness rating (5).
Two pumps of hand soap were applied to the dirty hands. The hands were rubbed together with soap for 20 seconds and followed by rinsing hands in tap water for 20 seconds. The hands were then blotted dry with paper towels for 20 seconds. Observations were made after cleaning the contaminated hands for cleanliness, lathering/rinsing, and skin condition. Cleanliness and lathering observations were made once and the skin condition was recorded at 1, 5, 20 and 60 minutes.
Observations were ranked using the following guidelines:
