摘要
化妆品的保湿性测定，通常是采用称重法，但其设备价格昂贵．而且只有进口产品。提出一种新的物理方法：根据化妆品电阻与其含水量之间呈规律性变化，电阻随含水量的减少而增大。该分析方法可作为检测化妆品的一条新途径。通过试验还证明了透明质酸的保湿性能高于山梨醇的保湿性能。就保湿性而言，透明质酸可以作为制造化妆品的新材料。
Weighing method has been generally used to determine the moisture holding capacity ofthe cosmetics. But the equipment is expensive and there is no such domestic product. We findthat another physical method is a promissing alternative. It is based on the principle that the resistance of the cosmetics changes with its moisture content regularly: The resistance increases withthe water reducing. Our experiment demonstrates that the moisture holding capacity of Hyaluronic Acid(HA) outweighs that of Sorbitol. Thus, HA is likely to be a good ingredient for cosmeticsproduction.
