preparation example Construction

[0033] The preparation method of described green antibacterial detergent provided by the invention comprises the following steps:

[0034] 1) Dissolving NP10 antimicrobial peptide in water to obtain A solution;

[0035] 2) Anionic surfactant and nonionic surfactant are mixed and dissolved with water under water bath conditions to obtain B solution;

[0036] 3) mixing and dissolving urea and water to obtain C solution;

[0037] 4) Mix and dissolve the C solution with sodium citrate, disodium EDTA, sorbitol and vitamin E, adjust the pH value of the obtained mixed solution to neutral, and obtain the D solution;

[0038] 5) Mixing the D solution with the A solution, B solution and C solution to obtain a green antibacterial detergent; wherein there is no time sequence limitation between steps 1) to 4).

[0039] The present invention has no special limitation on the mixing method, and a mixing scheme well known in the art can be used. The temperature of the water bath is preferab...

Abstract

The invention provides a green antibacterial detergent with NP10 antimicrobial peptide and a preparation method and application of the green antibacterial detergent and belongs to the technical field of detergents. The green antibacterial detergent is prepared from, by mass, 14-20% of an anionic surfactant, 4-12% of a nonionic surfactant, 0.10-0.15% of the NP10 antimicrobial peptide, 0.08-0.12% of sodium citrate, 1-3% of urea, 0.08-0.12% of EDTA disodium, 0.1-0.3% of sorbitol, 0.1-0.3% of vitamin E and the balance water. According to the NP10 antimicrobial peptide, in cooperation with the sodium citrate, the bacterium inhibition performance is improved, in cooperation with the anionic surfactant and the nonionic surfactant, the decontamination capacity can be improved, and the green antibacterial detergent also has the performance of resisting hard water. The green antibacterial detergent has the excellent decontamination capacity and can also moisten and protect the skin, the antimicrobial peptide has an excellent antimicrobial function, the application quantity of the green antibacterial detergent is lower than that of a chemical antibacterial agent, and the green antibacterial detergent is healthier than the chemical antibacterial agent.

Description

technical field [0001] The invention belongs to the technical field of washing liquid, and in particular relates to a green antibacterial detergent containing NP10 antibacterial peptide and a preparation method and application thereof. Background technique [0002] Dishwashing liquid is a daily consumer product. It is clean and gentle, with soft and fine foam, which can quickly decompose greasy, has the effect of fast decontamination and sterilization, and can effectively clean tableware, fruits and vegetables. Most conventional detergents on the market rely solely on chemical preservatives to kill bacteria and inhibit bacteria, which are difficult to degrade, have poor antibacterial effect, and are highly irritating to the skin. Therefore, there is an urgent need for a strong antibacterial ability, no irritation to the skin, no side effects on the body, and environmental protection Harmless antimicrobial additives. [0003] The patent with the publication number CN10752343...
