Description
Technical field
The present invention relates to a kind of washing liquid, particularly relate to a kind of proteolytic enzyme Superconcentrated washing liquid and preparation method thereof, belong to household chemicals field.
Background technology
Along with the development of modern society, household detergent, also by soap, washing powder, has slowly developed into washing liquid of today, a new generation washing liquid also gradually accept by domestic consumer, market there is the laundry liquid product of number of different types.
Although washing liquids many on the market has various function, still there is weak point.Make a general survey of washing liquid on the market, conventional products is in the majority, makes these washing liquids to some stains like this, as bloodstain, protein spot and fats spot can not thoroughly remove pointedly or removal effect not good.On the other hand, current washing liquid is on the market mostly coventional type, concentrated type is little, and according to industry development trend, concentrated type product more and more will be subject to the welcome of human consumer, because concentrated type product can save energy consumption, and be also very large saving on raw material and packaging material, although the price of concentrated type product is higher than coventional type product, its result of use is also apparent, by contrast, the cost performance of concentrated type product is higher.
Summary of the invention
The technical problem to be solved in the present invention overcomes the deficiencies in the prior art, provides a kind of proteolytic enzyme Superconcentrated washing liquid and preparation method thereof.
For solving the problems of the technologies described above, the technical scheme that the present invention proposes is:
A kind of proteolytic enzyme Superconcentrated washing liquid, described washing liquid forms primarily of the raw material of following mass percent: the nonionogenic tenside of 3% ~ 38%, the anion surfactant of 1% ~ 22%, 0.1% ~ 1% proteolytic enzyme, 0.1% ~ 2% trolamine, the Trisodium Citrate of 0.1% ~ 2%, the purified salt of 0.1% ~ 2% and 60% ~ 70% deionized water; Described proteolytic enzyme comprises bio protease and compound protease.Trolamine has good emulsifying, removes the effect of sebum greasy dirt, and has fabulous consistency.Proteolytic enzyme has the feature of natural, environmental protection, nontoxic, efficient removal protein stain, and has good compatibleness and consistency with negatively charged ion and nonionogenic tenside.
Above-mentioned washing liquid, preferably, described nonionogenic tenside is fatty alcohol-polyoxyethylene ether-7(AEO-7), fatty alcohol-polyoxyethylene ether-9(AEO-9), fatty alcohol-polyoxyethylene ether-3(AEO-3), one or more in alkyl glycoside, cocoanut fatty acid diethanolamide, isomeric alcohol polyethenoxy ether.Nonionic surface active agent of the present invention has well emulsify, solublization to greasy dirt.Wherein AEO-3 is water-insoluble tensio-active agent, but it and other tensio-active agent compounds, water soluble, increases surfactivity greatly, increases perviousness and oil removing power, can also increase viscosity.AEO-7 is low water solubility tensio-active agent, and emulsification greasy dirt power is strong, and AEO-9 is hydrophilic surfactant active, has good emulsifying, washing, soil-removing action.Cocoanut fatty acid diethanolamide (6501) is soluble in water, have good foaming, steady bubble, function such as infiltration decontamination, anti-hard water etc.Isomeric alcohol polyethenoxy ether is soluble in water, has excellent emulsification, washing performance.Alkyl glycoside (APG-0810) belongs to novel nonionogenic tenside, has the characteristic of conventional nonionic and anion surfactant concurrently, and thickening, thickening, detersive power are remarkable; There is good solubility, mildness, little to skin irritation, nontoxic and easily rinsing.
Above-mentioned washing liquid, preferably, described anion surfactant is one or more in polyoxyethylenated alcohol sodium sulfate, Sodium dodecylbenzene sulfonate, alpha-olefin sodium sulfonate.Sodium dodecylbenzene sulfonate (LAS) foaming power is strong, and detersive power is high, easily with various additive compound.Polyoxyethylenated alcohol sodium sulfate (AES) is the good anion surfactant of anti-performance of hard water, removes solids foul ability strong.It is good that alpha-olefin sodium sulfonate (AOS) belongs to biological degradability, has good stability in hard water and good soil-removing action.
Above-mentioned washing liquid, preferably, described washing liquid also comprises the essence that mass percent is 0.1% ~ 0.3%.The interpolation of essence has good flavouring effect to washing liquid.
Above-mentioned washing liquid, preferably, described washing liquid also comprises pigment.Add the color that appropriate pigment can regulate washing liquid system, increase aesthetics.The addition of pigment is few, 1,000,000 about two.
Above-mentioned washing liquid, preferably, in described washing liquid, the mass percent of activeconstituents is not less than 31%.
As a total inventive concept, the present invention also provides a kind of preparation method of above-mentioned washing liquid, comprises the following steps:
1) choose 70% ~ 80% of deionized water quality in formula, add nonionogenic tenside and anion surfactant after being heated to 40 ~ 50 DEG C, stir, obtain surfactant soln;
2) add trolamine, Trisodium Citrate in the surfactant soln obtained in step 1), after stirring, be cooled to less than 30 DEG C, obtain mixing solutions;
3) in step 2) after mixing solutions in add proteolytic enzyme and purified salt, add remaining deionized water, after stirring filter, namely obtain described washing liquid.
Above-mentioned preparation method, preferably, in described step 3), also adds essence.
Above-mentioned preparation method, preferably, in described step 3), also adds pigment.
Compared with prior art, the invention has the advantages that:
1) proteolytic enzyme Superconcentrated washing liquid of the present invention, product partial neutral, the pH value of system is between 7.5 ~ 8.0, character is gentle, and non-stimulated, tensio-active agent used all belongs to non-stimulated raw material, therefore feel is soft, after washing, can not basic residual be left, can not the symptoms such as allergic be caused, also damage can not be had to fabric, simultaneously soluble in water again, easy to use, consumption is convenient to control, be convenient to store, easy to use.
2) proteolytic enzyme Superconcentrated washing liquid of the present invention, effective active component content is not less than 31%, far away higher than washing liquid common on the market.
3) proteolytic enzyme Superconcentrated washing liquid of the present invention, functional comparatively strong, a kind of washing liquid can use as multiple washing composition, also the soft sterilization of tool and protect the function of look.
4) tensio-active agent that proteolytic enzyme Superconcentrated washing liquid of the present invention uses has foam stabilizing effect, and detersive power effect is far superior to laundry liquid product general on the market, and foam is few, and twice rinsing can reach without basic residual.
5) in proteolytic enzyme Superconcentrated washing liquid of the present invention, anion surfactant and nonionogenic tenside are carried out composite, then add after various auxiliary agent becomes washing liquid finished product, textile stains is had to the removal effect of synergy.As AEO-9,6501 and AES, AOS, LAS composite, greatly can strengthen the emulsification to greasy dirt, removal effect, simultaneously make again compound system have stronger resistance to hard water.
