Description

Technical Field

[0001] The invention relates to the field of daily chemical washing, and in particular to a preparation method of a novel dishwashing liquid. Background Art

[0002] With the improvement of living standards and the acceleration of people's pace of life, more and more families have begun to use dishwashers to wash dishes. There are many types of dishwashing liquids on the market, but most of them contain chemical synthetic ingredients, which are harmful to the human body after long-term use. Therefore, it is urgent to develop a safe and environmentally friendly dishwashing liquid.

[0003] However, the dishwashing liquid in the related art has the problems of single formula and relatively simple functions. Summary of the invention

[0004] The object of the present invention is to provide a method for solving the problems mentioned in the above background technology.

[0005] In order to solve the above technical problems, the present invention provides a technical solution: a method for preparing a new dishwashing liquid, comprising the following steps:

[0006] (a) adding deionized water into a container, and then sequentially adding sodium dodecylbenzene sulfonate and fatty alcohol polyoxyethylene ether, and stirring to mix them uniformly;

[0007] (b) dissolving a thickener in water to obtain a thickener solution, which is then added to the mixture obtained in (a) and stirred to obtain a viscous liquid;

[0008] (c) adding a pH adjuster to the viscous liquid obtained in (b) to adjust the pH value until the pH value reaches 7-9;

[0009] (d) after the liquid obtained in (c) has cooled to room temperature, adding preservatives and natural flavors and stirring evenly;

[0010] (e) Finally, the liquid obtained in (d) is bottled to obtain the desired dishwashing liquid.

[0011] Preferably, the mass percentage concentration of the sodium dodecylbenzene sulfonate is 10% to 15%.

[0012] Preferably, the mass percentage concentration of the fatty alcohol polyoxyethylene ether is 8% to 12%.

[0013] Preferably, the thickener is sodium carboxymethyl cellulose, and the mass percentage concentration of the sodium carboxymethyl cellulose is 1% to 2%.

[0014] Preferably, the pH regulator is sodium carbonate, and the mass percentage concentration of the sodium carbonate is 0.5% to 1%.

[0015] Preferably, the preservative is potassium sorbate, and the mass percentage concentration of the potassium sorbate is 0.1% to 0.3%.

[0016] Preferably, the natural flavor is a natural fruit flavor, and the mass percentage concentration of the natural fruit flavor is 0.05% to 0.1%.

[0017] The invention has the advantages that by adding raw materials in different proportions, the produced dishwashing liquid has good cleaning effect and high safety, wherein sodium dodecylbenzene sulfonate as a surfactant can reduce the surface tension of water, disperse oil stains in water, and thus achieve a cleaning effect; fatty alcohol polyoxyethylene ether can increase foam stability and enhance the washing effect; sodium carboxymethyl cellulose as a thickener can keep the dishwashing liquid at a certain viscosity, which is convenient for use; sodium carbonate is used to adjust the pH value, so that the dishwashing liquid is weakly alkaline, which is conducive to removing grease; potassium sorbate as a preservative can extend the shelf life of the dishwashing liquid; and natural fruit flavor can give the dishwashing liquid a fresh aroma, thereby improving user experience. DETAILED DESCRIPTION

[0018] For the purpose of the following detailed description, it should be understood that the present invention may adopt various alternative changes and step sequences, unless expressly specified to the contrary. In addition, except in any operating examples, or otherwise indicated, all numbers representing the amount of ingredients used in the specification and claims should be understood to be modified by the term "about" in all cases. Therefore, unless otherwise indicated, the numerical parameters set forth in the following specification and the attached claims are approximate values ​​that vary according to the desired performance to be obtained by the present invention. At least it is not intended to limit the application of the doctrine of equivalents to the scope of the claims, and each numerical parameter should at least be interpreted according to the number of reported significant figures and by applying ordinary rounding techniques.

[0019] Notwithstanding that the numerical ranges and parameters setting forth the broad scope of the invention are approximations, the numerical values ​​set forth in the specific examples are reported as precisely as possible. Any numerical value, however, inherently contains certain errors necessarily resulting from the standard deviation found in their respective testing measurements.

[0020] In addition, it should be understood that any numerical range described herein is intended to include all subranges subsumed therein. For example, a range of "1 to 10" is intended to include all subranges between (and including) the stated minimum value of 1 and the stated maximum value of 10, i.e., having a minimum value equal to or greater than 1 and a maximum value equal to or less than 10.
