Synopsis Several high‐temperature liquid chromatography ( HTLC ) and subcritical water chromatography ( SBWC ) methods have been successfully developed in this study for separation and analysis of preservatives contained in O lay skincare creams. Efficient separation and quantitative analysis of preservatives have been achieved on four commercially available Z ir C hrom and W aters XB ridge columns at temperatures ranging from 100 to 200°C. The quantification results obtained by both HTLC and SBWC methods developed for preservatives analysis are accurate and reproducible. A large number of replicate HTLC and SBWC runs also indicate no significant system building‐up or interference for skincare cream analysis. Compared with traditional HPLC separation carried out at ambient temperature, the HTLC methods can save up to 90% methanol required in the HPLC mobile phase. However, the SBWC methods developed in this project completely eliminated the use of toxic organic solvents required in the HPLC mobile phase, thus saving a significant amount of money and making the environment greener. Although both homemade and commercial systems can accomplish SBWC separations, the SBWC methods using the commercial system for preservative analysis are recommended for industrial applications because they can be directly applied in industrial plant settings.
