Method for detecting microorganisms in cosmetics of same dosage form

The invention provides a method for detecting microorganisms in cosmetics of the same dosage form. The detection method specifically comprises the following steps: (1) respectively adding a to-be-detected cosmetic A, a to-be-detected cosmetic B and a cosmetic C containing determined microbial counts into a solvent for dilution to obtain respective to-be-detected solutions, wherein the cosmetic A,the cosmetic B and the cosmetic C are cosmetics of the same dosage form; and (2) respectively putting the to-be-detected solutions of the cosmetics obtained in the step (1) into a culture dish, mixing, pouring a mould and yeast culture medium, carrying out mould and yeast culture, and counting bacterial colonies; respectively putting the to-be-detected solutions of the cosmetics obtained in the step (1) into another culture dish, pouring a bacteria culture medium, carrying out bacterial culture and counting bacterial colonies. According to the detection method disclosed by the invention, the detection cost is reduced,
