Abstract

The invention discloses a rapid detection method for forbidding sudan red dye in a lipstick. The method comprises the following steps that 1, a triangular carrier is manufactured, and the surface of the triangular carrier is evenly painted with a lipstick sample to be detected; 2, a detection device is manufactured, wherein the triangular carrier is placed at the front end of a sample inlet of an ion trap mass spectrometer; 3, detection is performed, wherein a dichloromethane, ethyl alcohol and formic acid mixed solution is added on the triangular carrier dropwisely, a high-voltage power source is adopted for applying 4.0-kilovolt voltage on a metal crocodile clip, the mixed solution extracts the sudan red dye to be detected in the lipstick sample, then migrates onto the triangular carrier in the direction of the tip end of the triangular carrier, and forms mist spray at the tip end, and detection is performed in a positive ion mode. The rapid detection method for forbidding sudan red dye in the lipstick can achieve accurate and rapid detection of the lipstick sample, and the adopted device is simple in structure, low in cost and easy and convenient to operate.

Description

technical field [0001] The invention relates to the field of cosmetic quality and safety detection, in particular to a rapid detection method for prohibited Sudan red dyes in lipsticks. Background technique [0002] Cosmetics are closely related to human life.
