Description
Technical Field
The invention relates to the technical field of cleaning products, in particular to an oil-removing antibacterial cleaning agent and a preparation method thereof.
Background
Currently, strong alkali type cleaners and solvent type cleaners are commonly used. The alkaline cleaning agent has good degreasing effect, but has strong alkalinity, has a corrosive action on skin, is easy to damage the skin of a user, and is easy to damage cleaning objects. The solvent-type cleaning agent mainly utilizes the dissolution of an organic solvent and the emulsification and solubilization of a surfactant to remove greasy dirt, and can cause certain loss to the skin of a user due to the large content of the organic solvent and relatively large smell.
Antibacterial components such as quaternary ammonium compounds such as benzalkonium chloride, sodium benzoate, glutaraldehyde and the like are often added into the existing cleaning agent, but the antibacterial components have the defects of high toxicity, difficult decomposition and the like.
Therefore, it is necessary to develop a nontoxic deoiling antibacterial cleaning agent.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide a nontoxic oil removal antibacterial cleaning agent and a preparation method thereof.
In order to achieve the above purpose, the technical scheme adopted by the invention is as follows:

According to the invention, polylactic acid modified chitosan oligosaccharide and alkaloid are introduced to serve as a bacteriostatic agent, so that the polylactic acid modified chitosan oligosaccharide and alkaloid are nontoxic to human and livestock, have biodegradability, and can enable the cleaning agent to exert a better bacteriostatic effect. The inventor researches find that the polylactic acid modified chitosan oligosaccharide has a certain adsorption effect on grease, and the adsorption effect on grease can obviously improve the oil dirt removing capability of the cleaning agent by matching with an anionic surfactant, a nonionic surfactant and sodium gluconate.
As a preferred embodiment of the present invention, the weight ratio of the A component to the B component is (10 to 20): 1.
as a preferred embodiment of the present invention, the a component comprises the following components in parts by weight: 15-20 parts of anionic surfactant, 20-30 parts of nonionic surfactant, 3-5 parts of sodium gluconate and 50-57 parts of deionized water.
As a preferred embodiment of the present invention, the component B comprises an alkaloid and a polylactic acid modified chitosan oligosaccharide, and the weight ratio of the alkaloid to the polylactic acid modified chitosan oligosaccharide is (0.1-2): 1.
further, the weight ratio of the alkaloid to the polylactic acid modified chitosan oligosaccharide is (0.5-1): 1. the inventor researches find that if the weight ratio of the alkaloid to the polylactic acid modified chitosan oligosaccharide is (0.5-1): in the range of 1, the stability of the component B is better, and the prepared cleaning agent can exert better antibacterial effect by compounding the alkaloid and the polylactic acid modified chitosan oligosaccharide.
As a preferred embodiment of the present invention, the nonionic surfactant is dodecyl glucoside.
In the invention, polylactic acid modified chitosan oligosaccharide, alkaloid, dodecyl glucoside and sodium gluconate all have antibacterial effect, and the synergistic effect of the components can effectively improve the antibacterial effect of the cleaning agent while ensuring the oil removal and scale removal effects.
As a preferred embodiment of the present invention, the anionic surfactant includes at least one of sodium dodecyl alcohol polyoxyethylene ether sulfate and sodium N-lauroyl sarcosinate.
Further, the anionic surfactant is prepared from sodium dodecyl alcohol polyoxyethylene ether sulfate and sodium N-lauroyl sarcosinate according to the following steps (1-3): 1 weight ratio.
As a preferred embodiment of the present invention, the alkaloid is at least one of matrine and berberine.
Further, the alkaloid is matrine and berberine according to the following formula 1:2 weight ratio.
As a preferred embodiment of the invention, the polylactic acid modified chitosan oligosaccharide is prepared by the following method: dissolving chitosan oligosaccharide in deionized water to obtain chitosan oligosaccharide solution; adding polylactic acid into N, N-dimethylacetamide, heating and stirring to dissolve the polylactic acid to obtain a polylactic acid solution; mixing the chitosan oligosaccharide solution and the polylactic acid solution, stirring for 6-12 hours at 40-50 ℃, coating the mixture on a substrate after vacuum defoamation, heating, evaporating to form a film, immersing the film in deionized water for 12-24 hours, and freeze-drying to obtain the polylactic acid modified chitosan oligosaccharide.
Further, the weight ratio of the chitosan oligosaccharide to the polylactic acid is (2-4): 1.
in a second aspect, the invention provides a preparation method of the deoiling antibacterial cleaning agent in the first aspect, which comprises the following steps:
mixing an anionic surfactant, a nonionic surfactant, sodium gluconate and deionized water to obtain a component A;
mixing polylactic acid modified chitosan oligosaccharide with deionized water to obtain a membrane dispersion; dissolving alkaloid in deionized water to obtain a alkaloid solution; mixing the biological alkali solution and the membrane dispersion liquid, performing ultrasonic treatment, and freeze-drying to obtain the component B.
The inventor researches that the alkaloid is difficult to preserve for a long time, which is probably due to loose molecular structure, poor stability and easy decomposition and deterioration of the alkaloid. The polylactic acid modified chitosan oligosaccharide is used as the water-soluble film to wrap the alkaloid, so that the cleaning agent can be stored for a long time, and the antibacterial effect is good.
Compared with the prior art, the invention has the beneficial effects that:
according to the invention, polylactic acid modified chitosan oligosaccharide and alkaloid are introduced, so that the polylactic acid modified chitosan oligosaccharide and alkaloid are nontoxic to human and livestock, have biodegradability, and have synergistic effects, so that the cleaning agent can play a better antibacterial effect.
According to the invention, dodecyl glucoside is used as a nonionic surfactant, dodecyl alcohol polyoxyethylene ether sodium sulfate and N-lauroyl creatine sodium are compounded to be used as an anionic surfactant, and sodium gluconate and polylactic acid modified chitosan oligosaccharide are combined, so that the oil removal and scale removal effects of the cleaning agent can be remarkably improved.
