A kind of mildy wash and preparation method thereof
Technical field
The present invention relates to a kind of bactericide, a kind of mildy wash and preparation method thereof specifically relates to a kind of biological bactericide and contains mildy wash of this biological bactericide and preparation method thereof.
Background technology
Mildy wash adopts the mode of washing to clean the emulsion form product of human body face skin exactly.At present the basis of mildy wash commonly used is water and surfactant, add additives such as essence, humectant, preservative, antioxidant with stable prod, compose with its fragrance.Its decontamination, cleaning action comprise it being wetting, osmosis by means of surfactant, make facial dirt be easy to come off, and with dirt emulsification, are scattered in the water then.
Though yet surfactant has good cleaning action, can not effectively kill and bacterium that portion hides, contain certain nutrient component toward contact because of it, make the Propiobacterium of in cleaning skin nutrition face, small pox is long more many more.
And the bacillus acnes that exists in the hair follicle of skin, staphylococcus albus and oval pityriasis sporeformer, particularly bacillus acnes contains the esterase that sebum is decomposed, intrafollicular sebum is decomposed by lipase and produces more free fatty acid, non-particularity inflammatory reaction takes place around making hair follicle and hair follicle in these free fatty acid, near the atomic ulcer of acne wall and free fatty acid enter behind the corium, add near the cell of blackhead extruding, make their antimicrbial power decline and caused inflammation by the infection of bacterium, so papule takes place in patient, warts, rhabdion, tubercle and abscess.
At present commercially available mildy wash kind is a lot, and its function mostly is cleaning, preserves moisture, skin moisten, whiten etc., and does not have sterilizing function.Mildy wash that has such as CN1148489A and CN1148490A, though certain bacteriostasis is arranged, good kill bacteria, and skin had certain excitant.Thereby develop and a kind ofly can effectively clean, preserve moisture, moisten skin of face, can effectively kill again the facial infection bacterium and to the skin action temperature and, non-irritating mildy wash, be the needs of existing market.
Summary of the invention
Problem to be solved by this invention is to provide a kind of biological bactericide to reach mildy wash that is mixed with by this bactericide and preparation method thereof, can not effectively remove facial bacterium, the shortcoming strong to skin irritation with mildy wash in the solution prior art.
The present invention at first provides a kind of bactericide, and this bactericide comprises staphylococcus lysozyme and lysozyme, and wherein the weight ratio of staphylococcus lysozyme and lysozyme is 1: 100-1: 400, and preferred ratio is 1: 200.
The present invention also provides a kind of mildy wash, this mildy wash is to be main fungicide active ingredient with above-mentioned bactericide, comprise surfactant simultaneously with cleaning action, surfactant be mainly action temperature and amphoteric surfactant, anion surfactant or non-ionic surface active agent.The component and the weight percent content of mildy wash comprise:
Bactericide 0.0001-0.1%
Surfactant 5-20%
Water surplus.
Staphylococcus lysozyme and activity of lysozyme unit's ratio are 1: 200;
Preferred ingredients and weight percent content comprise:
Bactericide 0.001-0.01
Surfactant 10-15%
Water surplus.
Preferred surfactants comprises one or more in imidazolinium betaine, fatty alcohol-polyoxyethylene ether, cocoa butter single ethanol amide, Cocoamidopropyl betaine, cocamidopropyl propyl amide amine oxide, trialkyl methyl oxidation amine, castor oil polyoxyethylene ether or the hydroxy sulfo lycine.
This mildy wash also comprises one or more in humectant, nutritional agents, emollient or the excipient.Wherein preferred humectant comprises one or more in propane diols, polyethylene glycols, glycerine or the sorbierite; Preferred nutritional agents comprises one or more in vitamin or the collagen; Preferred emollient comprises one or more in water-soluble modified silicone oil, cation-modified silicone oil, amino-modified silicone oil and the amino composite modified silicone oil; Preferred excipient comprises one or more in polyvinylpyrrolidone, two stearic acid polyethylene glycol or the cationic cellulose.
The present invention also provides the preparation method of this mildy wash, and surfactant, humectant etc. is dissolved in the solvent about 70 ℃, stirs, and is cooled to 40-50 ℃ then, adds bactericide, stirs, and gets final product.Said process all carries out under germ-free condition.
Characteristics of the present invention:
1. bactericide of the present invention is the purpose that reaches sterilization with the glycine peptide bond in the cracking bacteria cell wall, thereby sterilizing ability is strong, effective (bactericidal effect sees Table 1-2), bacterium is difficult for producing drug resistance, and because of its main component is a biologic product, to body, mucocutaneous without any side effects.
2. compositions such as bactericide and surfactant, humectant, emollient are carried out the composite mildy wash that forms, supplementary element not only makes biotype bactericide stability strengthen, help preserving (stability test sees Table 3), and make its bactericidal activity enhancing be original 2-10 times.
Effective cleaning, preserve moisture, moisten, skin-protecting function, and can strengthen skin elasticity;
To the skin action temperature and, nonirritant;
5. after skin absorbs, because be biology enzyme and can not cause any toxic and side effect to body.
Shanghai Disease Prevention and Control Centre is detected every index of this mildy wash:
1. basic the detection
