ActiveDetermination of metronidazole and norfloxacin in toothpaste—High performance liquid chromatography method
牙膏中甲硝唑和诺氟沙星的测定 高效液相色谱法
Application Summary AI generated
This standard specifies a high-performance liquid chromatography (HPLC) method for detecting the banned antibacterial agents metronidazole and norfloxacin in toothpaste. It is applied by quality control laboratories and regulatory bodies to ensure toothpaste products sold in China do not contain these illegally added antibiotics, which are prohibited due to risks of bacterial resistance and allergic reactions. The method provides a precise, quantitative basis for compliance testing in the cosmetics and oral care product industry.
