对以松茸为主要功效成分的化妆品进行人体美白功效评价。选择30名20~45岁女性,按要求在曲臂内侧使用化妆品8周后,测试使用前后皮肤MI值,L*值和ITA°值,实验结果均有显著性差异(P0.05)。Duncan多重比较表明,松茸化妆品的美白功效与抗坏血酸乙基醚化妆品相当,且显著大于配方基质。实验通过数据采集与统计分析,可直观反映化妆品中活性添加剂的美白效果,适用于添加活性物质的化妆品的美白功效评价。

Evaluation for whitening efficacy of cosmetics containing extract from Tricholoma matsutake Sing

Evaluation for human body whitening efficacy of cosmetics with extract from Tricholoma matsutake Sing as main effective constituent was conducted. Thirty female volunteers with age between 20 and 45 years old were kindly invited to use the cosmetic product on the inner side of their crank arm for a testing period of 8 weeks continuously. Values of MI, L* and ITA° of the skin were measured and the results display significant difference (P<0.05) before and after the 8 weeks testing period. Duncan multiple comparisons showed that the whitening efficacy of cosmetic product formulated with the extract from Tricholoma matsutake Sing is significantly greater than that of the formulation matrix and equivalent with that of ascorbyl ethyl ether. Via the data collection and statistical analysis, this method can directly reflect the whitening effect of active additives in cosmetics, and it is suitable for the evaluation of the whitening efficacy of cosmetics with additives.
