By investigating the extraction technology of dandelion,the best extraction technologywas selected and flavonoids were extracted from dandelion to be used as antibacterial components inhand sanitizer.The surfactants were fatty Sodium Alcohol Ether Sulphate(AES)and Cocoamidopropyl Betaine(CAB).The ovtimal ratio was determined by analvzing the ratio of AES and CAB.AES+CAB(mass fraction of 30%,AES:CAB=1:2),glycerin(mass fraction of 3%),linden honey(massfraction of 1%),essence(mass fraction of 0.1%),dandelion extract(mass fraction of 50%)wereselected by the experimental variables.The experiment proved that the PH of the hand sanitizer issuitable for human body,the viscosity is suitable,the foaming proverty meets the reauirements,andit can inhibit the growth of S.ureus(Staphylococcus aureus)and E.cooil(E.coli)
