化妆品中吡咯烷酮羧酸钠的测定 高效液相色谱法
Application Summary AI generated
This standard specifies a high-performance liquid chromatography (HPLC) method for determining the concentration of sodium PCA (pyrrolidone carboxylic acid sodium salt) in cosmetic products. It is applied by quality control laboratories and regulatory testing bodies to verify ingredient labeling compliance and ensure product safety in formulations such as moisturizers, serums, and cleansers. The method provides a reliable, quantitative approach for analyzing this humectant in complex cosmetic matrices.
