This standard specifies the method points, reagents and reference materials, instruments, analysis steps, result calculations, recovery rates, standard deviations and tolerances for the determination of allantoin in toothpaste by high-performance liquid chromatography. This standard is applicable to the determination of allantoin content in toothpaste, mouthwash and tooth powder. The detection limit of allantoin in this standard is 0.08 μg/mL, and the lower limit of quantification is 0.20 μg/mL. If a 1.0 g sample is taken, the minimum detectable concentration of allantoin is 8 mg/kg, and the minimum quantitative concentration is 20 mg/kg.
