Detailed ways

In order to better illustrate the purpose, technical solutions and advantages of the present invention, the present invention will be further described below with reference to specific embodiments.

Example 1

Embodiment 1 is a kind of bactericidal cleaning agent with color indicating function, and its composition and content are shown in Table 1, wherein, Crodaquat DGR is a surfactant mixture produced by British Croda Company, and it contains cocamidopropyl amine oxide. and PEG-2 Coco Methyl Ammonium Chloride.

The weight percentage/% of each component in table 1 germicidal cleaning agent

The preparation method of the bactericidal cleaning agent with color indicating function comprises the following steps: dissolving the mixture of sodium metasilicate, cocoylpropyl amine oxide and cocoyl methyl ammonium chloride in deionized water to obtain a solution, Diclosan and phenolphthalein are pre-dissolved in ethanol, then added to the above solution, and stirred evenly to obtain the germicidal cleaning agent.

Application of the bactericidal cleaning agent with color indication function: spray the bactericidal cleaning agent on the surface of the object to be cleaned, and when the foam fades to white, wipe the surface of the object with a towel to complete the operation of bactericidal cleaning.

Example 2-18

Examples 2-18 are all bactericidal cleaning agents with color indicating function, and the ingredients and contents thereof are shown in Table 1. The preparation method and application of these germicidal cleaning agents with color indicating function are the same as those in Example 1.

Comparative Examples 1-6

Comparative Examples 1-6 are all bactericidal cleaning agents with color indicating function, and the ingredients and contents thereof are shown in Table 1. The preparation methods of these bactericidal cleaning agents with color indicating function are the same as those in Example 1.

The effect of the germicidal cleaning agent with color indicating function was tested by the following method: Fill the germicidal cleaning agent with color indicating function in Examples 1-18 and Comparative Examples 1-6 into a watering can, press the foam pump, spray The foam is produced, and the color of the foam is visually observed, and the color is divided into five grades: extremely light, lighter, normal, dark and extremely dark; calculate the foam fading time, and the fading time is the time required for the foam to be sprayed until its color fades to white. The sterilization rate of Escherichia coli, Staphylococcus aureus and Candida albicans was tested respectively, and the average value of the sterilization rate of these three bacteria was calculated. The specific test results are shown in Table 2.

Table 2 Performance test results of germicidal cleaners with color indicating function

It can be seen from Table 2 that the content of the color indicator is related to the color depth of the bactericidal cleaning agent and has nothing to do with the fading time. When the content of the color indicator is less than 0.05%, the color of the foam is too light, which affects the user's judgment on the color change of the foam. When the indicator content is more than 0.5%, the color of the foam is too dark, which affects the user's visual experience, and the cost is also high. When the color indicator content is 0.3-0.5%, the foam color is suitable and the user experience is better; pH indicator content and The fading time is related to the sterilization rate. The fading time increases with the increase of the pH regulator content, and tends to be stable after reaching a certain level. When the pH regulator content is less than 0.1%, the foam fading time is too short, resulting in the ineffective sterilization cleaning agent. Sterilization, that is, the degree of conformity between the foam fading time and the effective sterilization time is relatively poor. When the pH regulator content reaches 1%, the average sterilization rate has reached 99.99%, and if it exceeds 1%, the bactericidal cleaning agent will be relatively high in alkalinity and have a certain degree of sterilization. When the pH indicator content is 0.3-0.5%, the pH value of the bactericidal cleaning agent is moderate, and the foam fading time can effectively match the effective sterilization time; the bactericide content is related to the bactericidal rate, and the bactericidal rate increases with the bactericide content When the content of the fungicide is less than 0.1%, the sterilization rate is relatively low. When the content of the fungicide is greater than 0.5%, the fungicide may have adverse effects on the human body. At the same time, the cost is also relatively low. High, when the sterilant content is 0.4-0.5%, not only the sterilization rate is high, but also safe; the surfactant content has nothing to do with the fading time and sterilization rate, when the surfactant content is less than 5%, the sterilization detergent foam comparison When the surfactant content is more than 15%, not only the cost is relatively high, but also it may have adverse effects on the human body. When the surfactant content is 5-15%, the foam is rich and safe; the organic solvent content and the fading time It has nothing to do with the bactericidal rate. When the organic solvent content is less than 2%, the organic solvent cannot dissolve the bactericide and color indicator well when preparing the bactericidal cleaning agent. When the organic solvent content is greater than 5%, the cost is relatively high. The solvent content is 2-5%.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit the protection scope of the present invention. Although the present invention is described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that, The technical solutions of the present invention may be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention.
