Now, in family, restaurant, dish washing detergent uses very general, and wash dining set uses dish washing detergent to become a kind of custom.Liquid dishwashing detergent has become the most salable liquid washing agent kind on the market, and the sales volume in the white cat dish washing detergent of light every year just reaches more than 100,000 tons.This shows that dish washing detergent is the very wide daily Betengent products of a kind of market outlook.

What mainly consider when the human consumer buys dish washing detergent is the price and the quality of product, if the measured product price of matter is relatively low, i.e. and reasonable words of the performance and price of product, the then easier favor of winning the human consumer.And the sensation of human consumer when being based on them and washing for the evaluation of dishwashing detergent product quality, the clean level during as the product dishwashing, viscosity, to several important index such as the mildness of hand skin, fragrance.Though viscosity index does not wherein reflect the quality of product soil removability, it is comparatively convenient that suitable product of viscosity uses, also more difficult leakage during transportation; While viscosity high product, the human consumer can feel that also the effective ingredient of product is more, soil removability is stronger.But viscosity is too greatly also bad, is difficult for during use pouring out.The viscosity of general dish washing detergent is that 600-800 is comparatively suitable when 25 spend.But meal lotion viscosity with temperature variation and change, temperature rising viscosity diminishes.The rational meal of a prescription lotion, viscosity with temperature changes the smaller the better.The human consumer can not feel-feel degradation because temperature raises.This point also is crucial concerning the meal lotion.

But, the dish washing detergent of selling on the market mainly is with one or both composite the forming in sodium alkyl benzene sulfonate, fatty alcohol-polyoxyethylene ether, these three kinds of tensio-active agents of alkylol amide now, though such product is if rationally then decontamination is also better for prescription, but owing to be subjected to the restriction of employed tensio-active agent kind, the ratio of performance to price of prescription is not so good; Gentle inadequately during 1 use, hand skin there is stimulation, wash the back and easily produce dry sensation; After 2 products were used the thickening material thickening, the variation of viscosity with temperature was bigger, and when the temperature rising, viscosity degradation is bigger; The restriction of the 3 sanitas kinds that added in addition, product have influenced the quality of product at quality guaranteed period content easy bacteria-developing.

The purpose of this invention is to provide the variation relatively good, gentle, viscosity with temperature of a kind of performance and price to skin less, in the quality guaranteed period not a kind of dish washing detergent and the manufacture method thereof of president bacterium.

Technical scheme of the present invention is: as main washing agent, it comprises with the tensio-active agent Recompounded multielement system of following components in weight percent:

A, washing agent contain one or more aliphatic alcohol sulfate analog anion surfactants, 5-20%, be preferably 5-10%, it can be fatty alcohol sulfate salt, polyoxyethylene alkyl ether sulfate salt, alkylphenol polyoxyethylene sulfuric acid etc., its alkyl can be that carbonatoms is the alkyl of 10-18, be preferably the alkyl of C12-C14, salt can be potassium, sodium, NH4 ⁺Or organic ammonium salt;

B, contain two or more different types of Sulfonates anion surfactant, 6-20% is preferably 6-15%, and it can be Sulfonateses such as alkylaryl sulphonate, alkylsulfonate, alkenyl sulphonate; Its alkyl can be that carbonatoms is the alkyl of 10-18, is preferably the alkyl of C12-C16, and its thiazolinyl is α-thiazolinyl preferably.

C, contain one or more alkylol amide class tensio-active agents, 2-10% is preferably 2-5%, it can be a coconut acid diethanolamide, Oleum Cocois formicester diglycollic amide, coconut monoethanolamide, the single isopropanol amide of lauric acid, Stearic acid diethanolamine salt, the stearic acid methyl ester diglycollic amide, stearic acid monoethanolamide, oleic acid diethyl amide, oleic acid formicester diglycollic amide, myristic acid single ethanol amide etc.Owing to adopted above tensio-active agent Recompounded multielement system, has good synergy between them, composite product detersive power than using single or two kinds of surfactant compound systems exceed one times nearly, the cost of product but has decline by a relatively large margin, save 0.1 yuan of calculating with every bottle 500 gram, can save 2,000 ten thousand yuan, improve the ratio of performance to price of product for annual 100000 tons.Owing to adopted more gentle polynary surfactant compound system, make product littler in addition to the pungency of hand skin.

D, in above-mentioned surfactant compound system, add extraordinary thickening material again, add-on is 3-5%, it can be sodium-chlor, Repone K, ammonia chloride, natural or synthetic resins etc., they have good thickening power to tensio-active agent Recompounded multielement system, and the variation of the viscosity with temperature of product is also less.When summer temperature was higher, the human consumer was difficult for feeling that the viscosity of product diminishes degradation.

E, also contain extraordinary solubility promoter at meal in the lotion, it can be sodium xylene sulfonate, urea, C ₁-C ₄Low mass molecule alcohol such as ethanol, Virahol etc., add-on are 1-5%.
