Research progress of the correlation between sensory evaluation and instrumental analysis of cosmetics in O/W emulsion system
With the rapid growth of the cosmetics industry,sensory evaluation is required when designing and optimizing products to meet consumers'increasing needs and aspirations.Instrumental measurement methods such as rheology measurement and texture analysis have the advantages of simple operation,lower cost,objective and repeatability,which can control individual differences when using"people"as a tool for sensory evaluation.This article reviewed the literature on sensory evaluation and instrumental analysis and characterization of cosmetics in the domestic and overseas,introduced the definitions of various sensory attributes in sensory analysis,summarized instrument parameters and test methods strongly related to sensory attributes,and listed fitting equations for some sensory attributes and instrument parameters,providing a scientific basis for the formulation design and screening of cosmetics during R&D.However,there was an incomplete study of the correlation between certain sensory properties and instrument parameters,such as visual acuity,softness,smoothness,moisture,and other sensory properties.Subsequent studies should also consider the differences in sensory properties of consumers with different skin types after cosmetics use.The information in this paper would help readers to understand the correlation between sensory evaluation and instrumental parameters,providing a scientific reference for the development of cosmetics with good skin sensation.
