It is well known that short-chain fatty acids, amines and steroids generated by microbial metabolism are the principal compounds responsible for body malodor. We newly identified vinyl ketones (1-octen-3-one, cis-1, 5-octadien-3-one) in body odor and found those ketones are also key compounds in axillary malodor. The purpose of this study was to develop a high performance powder, which has quenching efficacy not only for the shortchain fatty acids and amines, but also vinyl ketones. By investigating various powders known to have quenching efficacy, we finally developed a highly porous silica bead containing magnesium oxide. We found that the superior deodorant effect performed by this powder was the result of the multiple effects of both an excellent physical adsorption capability due to its high porosity and a specific adsorption of vinyl ketones to the magnesium in the powder. An antiperspirant formulation containing both the powder and Morus alba extract showed good efficacy as a deodorant.
