The invention discloses an
antimicrobial and antidandruff composition and application thereof. The composition comprises a
pyrithione polyvalent
metal salt and an alkoxy aromatic
amidine compound, and preferably comprises
zinc pyridine thione and
hexamidine isethionate, wherein the weight ratio of the
zinc pyridine thione to the
hexamidine isethionate in the composition is 1:20-10000:1. The composition can be applied in washing-off systems such as liquid shampoos, hair conditioners, facial cleansers, dermatophytosis removal products or
shower gel and the like which have the effects of sterilization and
antibiosis. The
antimicrobial and antidandruff composition can provide the high-efficiency effect of
dandruff removal and sterilization, overcome the defect that the effects of
dandruff removal, sterilization and
itching relieving are not obvious due to the
single use of any one component in the composition under the same condition, and play an excellent role in the
dandruff removal, sterilization and
itching relieving; and the
zinc pyridine thione and the
hexamidine isethionate have the synergic effect on the using effect, and the composition is used in products under the same using condition and using amount to reduce the amount used when only
single component in the composition is used effectively, so the effects of the dandruff removal and
itching relieving can be achieved.
