The anti-redeposition agent is preferably one or a combination of two or more of the following: sodium carboxymethylcellulose, sodium hydroxypropylmethylcellulose, hydroxybutylmethylcellulose, polyvinyl alcohol, polyvinylpyrrolidone. the

The chelating agent is preferably one or more mixtures of the following: ethylenediaminetetraacetic acid sodium salt, sodium citrate. the

The preparation method of the laundry detergent comprises the following steps: (1) adding accurately measured anionic surfactants and deionized water into a stirring tank, heating up to 60° C., and stirring until completely dissolved; (2) slowly adding accurately measured non-ionic surfactants Ionic surfactant and ε-polylysine are stirred until they are completely dissolved, cooled, and observed in the reaction kettle until a transparent and uniform solution is completely formed; (3) add other additives, leave it to defoam after all dissolve, and then prepare Antiseptic laundry detergent containing ε-polylysine. 

The feature of the present invention is that the biological preservative ε-polylysine is used as the bactericidal active ingredient, which has remarkable antibacterial and bactericidal effects, and has inactivation effects on Gram-positive bacteria, negative bacteria, molds, yeasts, and viruses, and has high safety. , non-irritating to the skin, strong detergency, phosphorus-free formula, green and environmental protection. the

Detailed ways
