GB/T 35799-2018 Translated English of Chinese Standard. (GBT 35799-2018, GB/T35799-2018, GBT35799-2018): Determination of Sodium PCA in Cosmetics - High Performance Liquid Chromatography

This Standard specifies the method of high performance liquid chromatography of determining sodium PCA in cosmetics (counted by pyrrolidone carboxylic acid). This Standard is applicable to the determination of sodium PCA (counted by pyrrolidone carboxylic acid) in creamy, milky and liquid cosmetics. In terms of sodium PCA (counted by pyrrolidone carboxylic acid), this Standard detection limit is 0.003%; its limit of quantitation is 0.01%.
