In order to control the function of solution products such as daily necessities, it is important to clarify the relationship between composition and structure. Therefore, we have considered a Cryo-TOF-SIMS/SEM method combined Cryo-TOF-SIMS and Cryo-SEM to analyze the composition and structure of solutions. As a result of analysis of a model fabric softener, spherical structures were observed and active ingredients were distributed at specific positions in the structures. The storage stability of two model softeners was discussed from the results of Cryo-TOF-SIMS/SEM. A new point of view for the formulation study of softeners was obtained through this research.
