Evaluation studies in the development of new types of cosmetics are divided into exploratory and confirmatory research. The exploratory evaluation aims to discover the unknown characteristics of tested products, whereas the confirmatory evaluation aims to examine the attainment of their designed quality. This report presents an evaluation method to achieve simultaneously the two objectives using the think‐aloud method with the paired comparisons method. The results obtained for two foaming cleansers possessed both exploratory aspects and confirmatory ones, and were straightforward in demonstrating the features of the foaming cleansers, because the think‐aloud method was not restricted by a complicated evaluation procedure. The method proposed from the discussions can be readily applied to the process of new product development.
