Abstract

The invention relates to a compound orthophaladetyde phenyl ammonium chloride disinfectant and a preparation method thereof. The compound orthophaladetyde phenyl ammonium chloride disinfectant comprises the following components by weight: 0.2-1 wt% of orthophaladetyde, 0.05-0.5 wt% of phenyl ammonium chloride, 0.1-1 wt% of dipotassium phosphate, 0.1-1 wt% of monopotassium phosphate, 0.1-0.3 wt% of sodium polyacrylate, 0.05-0.2 wt% of antioxidant, 0.01-0.1 wt% of disodium ethylene diamine tetraacetic acid and the balance of water. The preparation method of the compound orthophaladetyde phenyl ammonium chloride disinfectant comprises the following steps of: adding the orthophaladetyde into water according to the content and components, and stirring for dissolving; adding the dipotassium phosphate, the monopotassium phosphate, the sodium polyacrylate, the antioxidant and the disodium ethylene diamine tetraacetic acid in sequence, and stirring for dissolving; and adding the phenyl ammonium chloride, and stirring for dissolving to obtain the compound orthophaladetyde phenyl ammonium chloride disinfectant. The disinfectant is applicable to the high-level disinfection of thermolabile medical apparatus and instruments. The disinfectant has no pungent smell, safety, low toxicity, stable properties and convenient use.

Description

technical field [0001] The invention relates to a disinfectant, in particular to a compound o-phthalaldehyde phenyl ammonium chloride disinfectant and a preparation method thereof. Background technique [0002] Phthalaldehyde is a new type of aldehyde chemical disinfectant, which has the characteristics of low corrosion, non-volatile, low irritation, and can be used directly without activation. It was used for endoscope disinfection in foreign countries in 1994. It was found to have a good disinfection effect. In 1999, o-phthalaldehyde was certified by the FDA of the United States. As a high-level disinfectant, it can be used to repeatedly treat heat-sensitive medical equipment, and it can quickly and high-level disinfect at a room temperature of 20°C. However, o-phthalaldehyde also has obvious disadvantages, mainly in that its killing effect on bacteria and spores is not ideal, and its properties are unstable and easily destroyed by oxidation.
