Sensory evaluation is a special type of in vivo experiment, and cosmetic sensory evaluation is an evaluation method to verify the subjective claims of cosmetic products such as skin feel. It is a scientific method in which people perceive the characteristics and properties of a substance through sight, smell, taste, touch, and hearing. The method does not require special instruments and equipment, chemical reagents, but the evaluation results are closely related to the evaluator's sensitivity, practical experience, and physiological and psychological factors, thus requiring a comfortable and uniform experimental environment, strong professionalism, experience, and repeatability of the evaluator, as well as good stability and consistency of the evaluation team.
The prerequisite for sensory evaluation experiments is the establishment of an evaluation team. The establishment of the evaluation team requires the screening and training of a certain number of evaluators, and the passing of consistency and repeatability tests to ensure that the results of the evaluation team are true and reliable.
