Summary: | The invention discloses an extraction method and a detection method of polyaminopropyl biguanide in cosmetics and raw materials, and the extraction method comprises the following steps: step 1, respectively weighing sodium tetraborate and lauryl sodium sulfate, adding water for dissolving, and uniformly mixing to obtain a separation buffer solution; diluting the separation buffer solution with water to serve as a sample extraction solution; 2, treating a sample by adopting the sample extraction solution to obtain a to-be-detected sample solution; the detection method comprises the following steps: step 1, preparing a standard stock solution and a standard series solution; and 2, connecting the to-be-detected sample solution and the standard series solution to a capillary micellar electrokinetic chromatography system, and detecting the to-be-detected sample solution and the standard series solution. According to the extraction method and the MEKC detection method provided by the invention, the defects that in |
