Abstract:

In order to determine the hormone- and amine-type forbidden antibacterial drugs in hair-care cosmetics, a high performance liquid chromatography-tandem mass spectrometry-based method for was proposed. Taking Schwarzkopf professional repairing and brightening hair care cream as the research object, using methanol as the extraction solution, the antibacterial drugs in hair care cosmetics were determined by octadecylsilane-bonded silica gel chromatographic column in multi-reaction detection mode. The results show that when 0.02 mol/L ammonium formate aqueous solution is used as the flow phase, the superimposed total ion current separation effect of hormone-type forbidden antibacterial drugs in hair care cosmetics is the best. The isotope abundance ratio is the highest. When the extraction solvent is methanol, the recovery rates of A-1 to A-10 hormone-type and B-1, B-2, and B-3 amine-type forbidden antibacterial drugs are the highest, which are greater than 90% and 95%, respectively. For this reason, this article uses methanol as the sample extraction solution for the determination of 10 hormone-type forbidden antibacterial drugs. The results show that in Schwarzkopf Professional Repairing and Brightening Hair Care Cream, the detection limits of 10 hormone-type forbidden antibacterial drugs and 3 amine-type forbidden antibacterial drugs are all lower than the quantitative limit. The recovery and precision of hormone-type forbidden antibacterial drugs are 84.7%-114.7% and 1.8%-9.8%, respectively. The recovery and precision of amine-type forbidden antibacterial drugs are 84.1%-93.9% and 1.4%-5.7%, respectively. The separation time is less than 2 min and the determination time is less than 4 min. In Schwarzkopf Professional Repairing and Brightening Hair Care Cream, there are no hormone-type forbidden antibacterial drugs and amine-type forbidden antibacterial drugs, and the measurement efficiency of antibacterial drugs can meet the measurement requirements.

Key words: high performance liquid chromatography-tandem mass spectrometry, hair care cosmetics, antimicrobial agents, multi-reaction detection mode
