Abstract

Abstract The invention is an improved disinfectant and sterilant in a chemical form. The disinfectant and sterilant formulation is based upon glutaraldehyde which must be in acidic form. The normal pH range for the disinfectant and sterilant is 3.0-3.5, however, under controlled circumstances the range may be 2.5-7.0; as the disinfectant and sterilant must be acidic, it cannot be over pH 7.0. In use as a disinfectant by immersion, the items or materials remain immersed for up to ten minutes. As a sterilant, the immersion is between six and ten hours. The disinfectant and sterilant consists of a plurality of chemicals mixed with the glutaraldehyde as a solution.
