Abstract

The invention discloses a method for simultaneously determining 15 forbidden androgens in cosmetics. The method comprises the following steps: (1) preprocessing a sample: extracting, purifying and concentrating the sample; (2) analyzing and determining the preprocessed sample by adopting an ultrahigh-efficient liquid chromatography-mass spectrometry / mass spectrometry. The method can simultaneously determine 15 forbidden androgens including adrenosterone, trenbolone, boldenone, fluoxymesterone, oxandrolone, androstenedione, nandrolone, metandienone, testosterone, dehydroepiandrosterone, clostebol, androstanolone, mestanolone, chlorotestosterone acetate and testosterone propionate. The method for simultaneously determining the 15 forbidden androgens in the cosmetics is accurate, rapid and sensitive. According to the method, effective scientific evidence and technical support can be provided for the inspection work of cosmetics and the quality control of the daily production.

Description

technical field [0001] The invention relates to a method, in particular to a method for simultaneously determining 15 prohibited androgens in cosmetics. Background technique [0002] In recent years, with the rapid development of the national economy and the continuous improvement of people's living standards, my country has become a major consumer of cosmetics in the world. Consumers have a more rational consumption concept, not only purely pursuing the brand effect of cosmetics, but also paying more attention to the cosmetics themselves. safety. Androgens are steroid hormones that can directly act on the skin. In the short term, they can promote skin elasticity, reduce wrinkles, treat acne, and promote hair growth. However, if used for a long time, it will cause pigmentation, skin atrophy and thinning and other side effects. my country's cosmetics hygiene standards, cosmetics hygiene standards, and EU cosmetics regulations clearly stipulate that androgen is a prohibited su...
