Carbonyl-containing compounds that have been tested include acetone, 2-pentanone, 4-hydroxy-4-methyl-2-pentanone, and camphorsulfonic acid. The method includes providing a solution containing the dioxirane reaction mixture and contacting the matter or materials with it at room temperature for a time sufficient to disinfect and sterilize the matter or materials.
