Abstract

The present invention discloses a liquid high-effective disinfectant. It is formed from (wt%) 1-2% of hyamine which is the mixture of alkyl dimethyl benzyl ammonium chloride and dialkyl dimethyl ammonium chloride, 0.1-0.5% of biguanide which is one of chlorhexidine and polyhexamethylene biguanide salt or their mixture, 3-8% of aldehyde which is one of glutaraldehyde, citrial, jasminal and myristic aldehyde or mixture of more than two kinds of them, 5-10% of surfactant, 1-5% of urea, 40-50% of hydrophilic solvent, 0.1% of EDTA sodium salt, 2.5-35% of water and 0-3% of selectable components, such as aromatic compound, colouring matter and viscosity-regulating agent.

Description

technical field [0001] The invention relates to the field of disinfectants, in particular to the field of liquid disinfectants. technical background [0002] The development of modern industry and human beings' concern about the hygienic environment have promoted the development of disinfectants and increased the demand for disinfectants. The current requirement for disinfectants is that when the disinfectant is in contact with the surface of an object or the air, it can effectively reduce the number of bacteria, fungi, yeast, and viruses or inhibit their activity in a short time. The "Technical Specifications for Disinfection" issued by the Ministry of Health of China stipulates the test methods for evaluating the disinfection and sterilization effects of disinfectants. The main bactericidal active ingredients of current commercially used disinfectants are peroxides, phenols, and halogen-containing compounds such as chlorine dioxide, sod...
