探讨5款配方配比的乳液类护肤化妆品在消费者使用中感官评价的区别，选用成对比较分析法对其进行感官上的定性评定，并且探讨成对比较分析法的原理和应用。通过成对比较分析法对5款不同配方的护肤乳液类化妆品进行感官评价分析，感官评价指标包括：铺展性、湿润度、厚重感、光亮度、滑爽感、残留量、柔软感、黏滞感等感官指标，运用数理统计中的方差检验对评分进行分析。结果显示，以4%PTID+10%IPP为配方的3号样品，在铺展性、湿润度、光亮度、滑爽感、柔软感等感官特性明显强于其他4款配方的样品，以4%DISD+10%IPP为配方的2号样品在残留量、黏滞感等感官特性明显强于其他4款配方的样品。通过本实验，基本建立了乳液类护肤化妆品感官评价的评价体系；对5款不同配方的样品进行测试，得到了针对不同感官评价指标结果较优的样品配方。
The differentiation of sensory evaluation for five kinds of formula of emulsion-type skincare cosmetics in consumers' usage is explored and the principle and application of the paired comparison method are studied. A sensory qualitative evaluation of five kinds of formula of emulsion-type skincare cosmetics is analyzed by using the paired comparison method; 10 sensual evaluation indexes ,such as spreading, wetness, thickness, gloss, slipperiness, type of residue, softness, and stickiness, etc., are used to conduct resultant inspection through variance test in mathematical statistics. Results reveal that the sample of formula of 4% PTID and 10% IPP is better than other four samples in spreading, wetness, gloss, slipperiness, and softness; the sample of formula of 4% DISD and 10% IPP is better than other four samples in term of residue and stickiness. This experiment fundamentally builds a sensory evaluation system for the emulsion-type skincare cosmetics and gains the best formulation of sample for different index results of sensory evaluation by testing five different formulations of samples.
