Separation of sunscreens in skincare creams using greener high-temperature liquid chromatography and subcritical water chromatography

International Journal of Cosmetic Science, 04/06/2012

The quantity of methanol consumed by the greener high–temperature liquid chromatographic (HTLC) sunscreen methods developed in this project is significantly reduced although the HTLC separation at this stage is not as efficient as that achieved by traditional HPLC. SBWC separation of sunscreens was also achieved on the XTerra MS C18 and the XBridge C18 columns using pure water at 230–250°C. Methanol was eliminated in the SBWC methods developed in this study.
