His inventive spirit and dedication to improving sterilization methods have made him a key figure in this important area of research.

Latest Patents

Among his latest breakthroughs is a novel sterilizing method that utilizes a peracetic acid-type sterilizing composition solution. This method involves the use of a solution containing peracetic acid, hydrogen peroxide, acetic acid, and catalase. The process is designed to heat the sterilizing composition in a circulating tank, feed it into a sterilizing unit, and subsequently recover it after use. By adding catalase in a circulating passage after sterilization but before it enters the heating unit, Takeshi has developed a process that maintains the effectiveness of the sterilizing solution and conserves heat energy. This advancement not only enhances the efficiency of sterilization but also brings economic advantages.

Another noteworthy patent by Iwashita involves a specialized peracetic acid-type sterilizing composition solution that optimally balances its ingredients: peracetic acid, acetic acid, hydrogen peroxide, and catalase enzyme. The formulation maintains a pH range of 2.6 to 5.0, allowing for reduced hydrogen peroxide concentration through the efficient action of catalase, which minimizes bubbling and enhances the usability of the solution.
