Abstract
- Preservatives are frequently added to cosmetics to maintain product quality. Our laboratory quantifies 11 preservatives in cosmetics each year for regulatory purposes. In laboratories, many manufactures also analyze the preservatives in their products for quality control. To analyze many cosmetic samples, a rapid analysis method is required for efficiency. In this study, we developed a rapid method for the simultaneous determination of 11 regulated preservatives in cosmetics using a core–shell column by high-performance liquid chromatography. In this method, the 11 preservatives were separated within 17 min, which was approximately half the time reported in the previous study. The peak resolution for each preservative was >2.6, the correlation coefficients of the calibration curves were >0.9988, the percent recoveries were 92.0–111.9% and the relative standard deviations were <3.5% (n = 3). The relative standard deviations among 6 researchers were <4.7%. Thus, it is an effective rapid determination method for the analysis of preservatives in cosmetics. [ABSTRACT FROM AUTHOR]
