Problems solved by technology

Traditional quaternary ammonium surfactants are not easy to degrade, have poor water solubility, and have poor compatibility with other surfactants. They are used for sterilization. Due to long-term and large-scale use, bacteria have developed resistance to them, and the antibacterial effect is not good.
Moreover, disinfection cleaning products are mainly effective against Escherichia coli and Staphylococcus aureus, but have no obvious effect on Candida albicans

Abstract

The invention discloses a laundry detergent with antibacterial effect, which comprises the following components in parts by weight: 10-15 parts of dodecyl dimethyl benzyl ammonium bromide, 5-10 parts of dioctadecyl dimethyl ammonium chloride 5-10 parts of ethylenediamine hydrochloride, 8-15 parts of fatty alcohol polyoxyethylene ether, 0.1-0.5 parts of thickener, 0.1-0.5 parts of chelating agent, 80-10 parts of deionized water 95 servings. The present invention adopts three kinds of cationic surfactants and nonionic surfactants to compound, and through the unique ratio, it can achieve synergistic antibacterial effect, not only can effectively kill Gram-positive bacteria and Gram-negative bacteria, but also It can kill fungi and has a good bactericidal effect.

Description

technical field [0001] The invention belongs to the technical field of daily chemical industry, and in particular relates to a laundry detergent with antibacterial effect. Background technique [0002] Since the outbreak of SARS in 2003, people have higher requirements for the cleanliness and sanitation of the clothes they touch, not only requiring the clothes to be soft and free of dirt, but also requiring no pathogenic bacteria on the surface of the clothes. Correspondingly, sterilization and disinfection washing products are developing rapidly. Disinfection and washing products mainly include antibacterial hand sanitizer, disinfectant laundry detergent and disinfectant, etc. The main bactericidal ingredients of these disinfection products are chlorine-containing (sodium hypochlorite, chlorine dioxide and sodium dichloroisocyanurate, etc.), Hydrogen oxide aqueous solution, sodium percarbonate, sodium perborate, etc.), phenols (such as p-chloro-m-xylenol), aldehydes (such ...
