The average value of 20 persons was calculated by setting 2 points when the foam was felt to be creamy, 1 point when the foam was felt to be slightly creamy, and 0 point when the foam was found to be rough rather than creamy. . If the average value is 1.5 points or more, the creaminess of the foam is considered to be good. (4) Feeling slimy after rinsing Twenty women were panelists, and 5 ml of body shampoo was taken on a sponge for bathing to wash fingers and forearms, and rinsed with 1 liter of hot water at about 40 ° C However, the slimy feeling after rinsing three times was evaluated. 4 points if you feel no slimy feeling, 3 points if you feel little slimy feeling, 2 points if you feel a little slimy feeling, 1 point if you feel a slimy feeling is persistent The average value of 20 persons was calculated. If the average value is 3.0 or more, it is considered as a body shampoo with no slimy feeling. (5) Refreshing feeling after rinsing Twenty women were panelists, and 5 ml of body shampoo was taken on a sponge for bath to wash fingers and forearms, and rinsed with 1 liter of hot water at about 40 ° C However, the refreshing feeling after rinsing three times was evaluated. 4 points if you feel a refreshing feeling, 3 points if you feel a little refreshing feeling, 2 points if you feel little refreshing feeling, 1 point if you feel no refreshing feeling at all The average value of 20 persons was calculated.
