We performed a study of MALDI-MS imaging that is a combination of an optical microscopy and MALDI mass spectroscopy. Mapping images of chemical materials were successfully obtained by applying 2,5-dihydroxybenzoicacid (DHB) as a matrix with a sublimation method. In this paper, we present two results: (1) the distribution of light stabilizers in a multi-layer synthetic film, and (2) the state of the penetration phenomena of hair conditioner chemical components in the hair shaft. In either case, a careful selection of m/z ion enabled successful mapping for individual components; and a variation of the distribution according to the type of components was revealed. Further, important implications with regard to the development design of the materials structure and chemical components were deduced. These results indicated that the MALDI-MS imaging method, which has been extensively used only for biomaterials, is also a powerful tool for the analysis of chemical materials.
