The disinfectant used in this example is a SteriBio-CID (brand of disinfectant) disinfectant, which is different from the existing disinfectant on the market today. Many disinfectants, along with turpentine oil to prevent organic substances from decomposing the fragrance and brown dye to mark liquids to prevent misuse in clinical settings, together make up a compounded formulation. Wherein the disinfectant comprises turpentine, n-alkyl dimethyl benzyl ammonium chloride, isopropanol, glutaraldehyde and didecyl dimethyl ammonium chloride.

The disinfectant is compounded and used, and can treat various bacteria, spores and viruses. The combination of multiple disinfectants produces a unique synergistic effect, allowing each disinfectant to be combined at very low concentrations while increasing the effectiveness of the disinfectant. The concentration of each disinfectant is so low that the SteriBio-CID disinfectant can be discharged to a sewer directly after use; at the same time, the low concentration of the disinfectant component also enables the use of the SteriBio-CID disinfectant in small equipment rooms. Wherein, the turpentine is a grade 1 disinfectant, and is also used as a medical waste deodorant to eliminate odor generated by high-temperature storage in the medical waste treatment process; the turpentine oil is used under the condition of the participation of isopropanol, and can also be used as an effective cleaning agent or degreasing agent, so that the tissue structure of a biomembrane in a sewage pipe can be decomposed, and the accumulation of blood fat on a medical waste treatment device can be prevented. Glutaraldehyde can invade the cell wall or spore capsule, cross-linking with essential cellular components, such as deoxyribonucleic acid, biological enzymes, and cell membranes, rendering the organism non-viable. The didecyl dimethyl ammonium chloride and the n-alkyl dimethyl benzyl ammonium chloride, namely quaternary ammonium compounds, can decompose capsules and cell walls and improve the spore permeability of glutaraldehyde; in addition, quaternary amine compounds can break down proteins and cell membrane components, making the cell membrane very porous and more susceptible to other disinfectants.
