  The present invention relates to a deodorant composition including (a) a polyhydroxyamine compound having a specific structure and/or a salt thereof, and (b) a penetrant including at least one substance selected from the group consisting of (b1) a nonionic surfactant having a specific structure, (b2) a surfactant having a residue of a monosaccharide, etc., (b3) a nonionic organic solvent having a log P value of from 0 to 4; and (b4) an amine oxide type or carbobetaine type amphoteric surfactant; as well as a deodorizing method using the deodorant composition. The deodorant composition of the present invention is capable of reducing or eliminating a composite odor derived from sweat smell and aldehydes, readily producing a water-based deodorant, and is safe for human use.

  The oxidation of allenes and alkynes with hydrogen peroxide catalyzed by peroxotungstophosphate (PCWP) was examined. A variety of allenes were first converted into the corresponding alpha-ethoxy ketones upon treatment with 35% H2O2 under the influence of PCWP in a mixed solvent consisting of ethanol and dichloromethane. When the reaction was carried out using tert-butyl alcohol as a solvent, approximately a 1:1 regioisomeric mixture of alpha-hydroxy ketones was obtained along with a small amount of alpha-tert-butoxy ketone. Oxidation of internal alkynes such as 4-octyne by the PCWP-H2O2 system under phase-transfer conditions using chloroform produced alpha,beta-epoxy ketones in good yields. The same reaction in a mixed solvent of ethanol and chloroform gave alpha,beta-unsaturated ketones rather than alpha,beta-epoxy ketones. Plausible reaction paths are proposed for the oxidation of allenes and alkynes by the PCWP-H2O2 system.
