The invention discloses a method for determining five forbidden miticides in cosmetics. The method comprises the following steps: (1) extracting samples ultrasonically by using methyl alcohol, centrifuging an extracting solution, taking liquid supernatant, drying and filtering; and (2) carrying out gas chromatography determination on filtrate, wherein a HP-55% phenyl methicone nonpolar quartz capillary column with the size of 30 meters*0.25 millimeter (i.d.)*0.25 micron is adopted as a chromatographic column, wherein the temperature of an injection hole is 220 DEG C, the flow velocity is 2mL/min, the programmed temperature conditions are as follows: the initial temperature is 80 DEG C and is kept for 1.5min, and is raised to 250 DEG C at the rate of 30 DEG C/min and is kept for 2min, and the split ratio of the injection hole is 5:1; the five forbidden miticides comprise chlorothalonil, captan, chinomethionat, myclobutanil and captafol. The method is accurate, reliable and simple, and has high specificity and the sensitivity.
