Quantitative Determination of Multiple Ingredients in Topical Formulation by Gas Chromatography
By CPLGas chromatography (GC) is a typical chromatographic method used to separate and quantitatively determine analytes that can be volatised without decomposition.
Many excipients widely used in topical semi-solid and liquid formulations, as solvents, humectants, surfactants, thickeners and preservatives, can be quantitatively tested by GC.
