超临界萃取技术及其在日用化工中的应用

Supercritical extraction technology and its applications in personal care product industry

简要介绍了超临界流体萃取技术和超临界流体分析技术。与其他常规萃取方法相比,超临界萃取具有操作温度低、萃取效率高和绿色环保等优点,特别适用于热敏性物质的提取、分离和分析。详细介绍了超临界萃取在日用化工上的应用:热敏物质的提取和与其他分析技术联用测定日化产品中特殊组分的含量。

Supercritical extraction technology and its uses in the chemical production as well as in laboratory analysis were briefed.Supercritical extraction technology has the advantages such as lower operating temperature,higher extraction efficiency and good environmental compatibility.The uses of supercritical extraction in cosmetic and tooth paste manufacture,particularly in the preparation,separation and purification of heat sensitive materials as well as the use of supercritical extraction in combination with other analysis technologies for the determination of special ingredients in cosmetics were introduced in details.
