PURPOSE:To obtain a solid deodorant having superior deodorizing power, durability for deodorizing power, and characteristic in easy handling being relatively inexpensive by incorporating glyoxal in porous particles or molded body of the porous particles of acetyl cellulose having specified characteristic value. CONSTITUTION:Glyoxal is incorporated to porous particles of acetyl cellulose having ca. 3-5mm dia. with 50-58% acetylation degree, >=0.7cc/g pore volume, pref. below 1,000Angstrom mean pore size, and >=10kg collapse strength, or to a molded body thereof. Usually 20-30% aq. soln. of glyoxal is impregnated by the conven tional method such as immersion, and the product is dried by heating. After drying, glyoxal is confined in the pores in the particles exhibiting higher deodor izing effect and durability of the deodorizing effect as compared to conventional zeolite or active carbon, etc., providing thus a solid deodorant. |
