ABSTRACT:
Compositions, devices, and methods are disclosed for achieving rapid sterilization. A device for reducing surface tension in liquids is also disclosed. Both cationic and anionic surfactants are simultaneously present and used with a germicide to accelerate sterilization at room temperatures. One device includes a tablet, absorbent body, or other carrier which carries both an anionic surfactant and a cationic surfactant. Another device includes a hermetically sealable envelope which contains an anionic surfactant and a cationic surfactant, preferably with a germicide which impregnates an absorbent liner. The composition includes a germicide, an anionic surfactant, and a cationic surfactant. Glutaraldehyde solutions are the preferred germicides; sulfosuccinic acid, ester with ethoxylated lauryl alcohol, disodium salt is a preferred anionic surfactant; and, a quaternary ammonium salt is the preferred cationic surfactant. A sterilization method is performed by exposing an object to the disclosed compositions.
