SIMULTANEOUS SCREENING METHOD FOR FUNCTIONAL INGREDIENTS IN COSMETICS

摘要

A simultaneous screening method for functional ingredients contained in cosmetics is provided to quickly analyze the functional ingredients having different chemical properties(solubility and polarity) with high separation rate. A simultaneous screening method for functional ingredients comprises the steps of: adding dimethyl formamide, methanol and water in cosmetic materials in a volume ratio of 1 : 0.9-1.2 : 0.1-0.05 to the mixed solvent and extracting functional ingredients from cosmetic materials; injecting the functional ingredients in a reversed phase non-polar column, wherein the reversed phase non-polar column is charged with octadecylsilane(C18), dodecylsilane(C12) or octasilane(C8) as a stationary phase; and injecting methanol or the mixed solvent of water and methanol a mobile phase to the column where functional component is injected.
