China cosmetics market is expected to remain fast growth during the “Thirteenth Five-Year Plan” period, in particular in small and medium-sized cities. It is estimated that the average growth rate of the overall market will reach about 10%, and the market scale will be close to 500 billion yuan by 2020.展开更多

They were separated on a Kromasil C18 column, with gradient elution by methanol and water, and detected by HPLC-DAD.All results demonstrated good linear relationship in proper mass concentration range. The limits of quantitation(LOQ) were between 0.5 and 1.25 mg/L. The recoveries of the six compounds ranged from 98.3% to 101.0% at two inrements with the relative standard deviation(RSD) no more than 1.5%.展开更多
