Title: Deodorant and manufacture thereof
Inventor: TAUCHI TATSUJI
IPC: A61L9/01
Filed: 1989-10-24
Abstract: PURPOSE:To efficiently remove various malodors by molding various pulps of thick paper form into a determined form after dry distillation. CONSTITUTION:A deodorant is formed by using various pulps of thick paper form and pulp sludge as starting materials, and dry distilling the starting materials. An extremely powerful deodorizer utilizing the deodorizing force possessed by the pulp made porous can be obtained. In the manufacture, the strength and deodorizing force of the fiber itself can be determined by regulating steam pressure in autoclave, temperature, and dry distillation time. The pulps can be selected from craft pulp, Manila help pulp, ditch reed pulp, bamboo pulp, and sisal pulp. For example, various pulps of thick paper form are dry distilled in an autoclave having a steam pressure of 3-6 kg/cm<2> at a temperature of 120-160 deg.C for 30 minutes to 2 hours followed by drying.
