Zusammenfassung:	PCT No. PCT/JP95/00489 Sec. 371 Date Sep. 13, 1996 Sec. 102(e) Date Sep. 13, 1996 PCT Filed Mar. 17, 1995 PCT Pub. No. WO95/25752 PCT Pub. Date Sep. 28, 1995An amphoteric porous particulate containing a basic polysaccharide and a polymer of an organic acid containing a reactive vinyl group or a salt thereof and having an average particle size of 50 mu m or less, is capable of adsorbing a large amount of an acid or a base that is stronger than the acid or basic groups thereof and is useful in a deodorant or a cosmetic. The amphoteric porous particulate is made by emulsifying or suspending an aqueous solution containing a basic polysaccharide and an organic acid having a reactive vinyl group in a hydrophobic solvent, followed by polymerization. A deodorant may be made of a chitosan particulate having an average particle size of 0.01 to 50 mu m. A polysiloxane having long-chain alkyl groups and a melting point of 20 DEG C. or above is useful as an oil component of a deodorant.
