As we make a refreshing shampoo formulation, in order to achieve the required quality, we have to examine the combination of the algefacient density, washing ingredients and conditioning ingredients. The evaluation of the performance for the formulated refreshing shampoo substantially depends on the result of quantitative research, such as the survey to consumers and the formulator's experimental rule. Those methods, however, are inaccurate because it is based on subjective data. To resolve the problem, with applying Emotion Fractal Analysis Method (EFAM) to electroencephalogram signals, we analyzed emotions such as sensation of coolness, refreshment, comfort and relaxation. The results showed that the correlation coefficient between evaluation value of EFAM and subjective assessment of refreshment was very high: 0.99. Those results point to a possibility that EFAM may be objectively measure particular human emotions.
