Q弹粉底霜感官特性与其质构参数相关性的研究

Study of the correlations between the sensory characteristics of elastic foundation creams and their textural parameters

对5款增稠剂含量不同的Q弹粉底霜进行了质构测试分析,并对其肤感进行了测试。质构仪结果表明,随着增稠剂含量的增加,产品的硬度不断增大,而弹性、黏性、内聚性等特征呈现先增大后减小的趋势。感官测试结果表明,产品涂抹时肤感的柔软性与质构硬度以及内聚性有较强的相关性,相关系数分别为0.909和0.745。膏霜的涂抹性与质构硬度具有显著负相关性,相关系数为–0.512。感官弹性参数与质构参数具有较强的相关性,其相关系数为0.774,且质构仪的其他各项参数均与感官测试有较好的相关性。这项研究对化妆品研发中,用仪器分析取代人体感官测试是很有意义的可行性尝试。

The textural and sensory analyses of five products of elastic foundation creams with different thickener content were carried out.The results obtained by a texture analyzer showed that,with the increase of thickener content,the hardness of the product increased gradually,while the springiness,adhesiveness,cohesiveness and other parameters were first increased and then decreased.The sensory results showed that the skin softness during the application of the product had a strong correlation with hardness and cohesiveness,and the correlation coefficients were 0.909 and 0.745,respectively.The spreadability of the foundation cream had significantly negative correlation with the textural hardness,with a correlation coefficient of-0.512.The elasticity(a sensory parameter)had a strong correlation with the springiness(a textural parameter),and the correlation coefficient was 0.774.The results showed that the parameters obtained by the texture analyzer had good correlation with the sensory tests.The study proved that it had potential to use instruments to predict sensory test results for cosmetic products.
