As shown in table 17, the difference in the cleaning effect and refreshing feeling of the shampoo after the gentian extract was removed was not obvious in comparative example 4, combination 1, compared to example 1, combination 3 and example 1, combination 5; but the anti-dandruff effect and the oil control effect are deteriorated. Wherein example 1, combination 3 and example 1, combination 5 are very significantly better than comparative example 4, combination 1, for antipruritic effect.
Comparative example 5 the shampoo has insignificant difference in cleaning effect and refreshing feel after the gentian extract is replaced by combination 1-3; however, for the antidandruff effect, antipruritic effect and oil control effect, example 1 combination 3 and example 1 combination 5 are significantly better than comparative example 5 combinations 1-3.
Thus, it can be seen that the antipruritic effect of example 1, combination 3 and example 1, combination 5 is more pronounced, and the overall evaluation effect is superior to the rejection or replacement of the compositions of comparative examples 4 and 5 in the gentian extract, in which the gentian extract exerts a significant antipruritic effect.
