Abstract:

The purpose was to establish a method for the identification of ten anti-acne compounds (benzoyl peroxide, spironolactone, tacalcitol, tazarotene, acitretin, isotretinoin, tretino-in, etretinate, viaminate, adapalene) in anti-acne cosmetics by high performance liquid chromatography and verification by liquid chromatography-tandem mass spectrometry. The samples were extracted by ultrasonic machine with methanol. The separation was executed on an Agilent ZORBAX Extend-C18 column by a mobile phase consisting of 0.5% acetic acid (A), methanol (B), with the flow speed of 1.0 mL/min. The qualitative screening results were obtained through high performance liquid chromatography with PDA detector at multi-wavelength, the standard curve method was used for quantification, and the results of liquid chromatography tandem mass spectrometry were used for verification. The results show that under the conditions of this method, the recovery rate is 80.8%-102.7%, and the relative standard deviation is less than 3.0%. Ten anti-acne compounds obtain a good linear relationship within their respective mass concentration ranges, and the correlation coefficients are all greater than 0.999 8. The detection limits are 0.1-1.0 mg/kg. This method can be used exclusively and quickly to screen and confirm ten anti-acne compounds added in anti-acne cosmetics. It is mainly suitable for the simultaneous determination of ten anti-acne compounds in anti-acne cosmetics.

Key words: high performance liquid chromatography, liquid chromatography-tandem mass spectrometry, anti-acne cosmetics, anti-acne
