A cleaning, disinfecting, skin-protecting and mosquito-preventing agent comprises the following components:
and (3) chitosan: 50 parts by weight;
45 parts by weight of octaglycerol stearic acid;
sodium benzoate: 5 parts by weight.
Compared with the embodiment 1, the comparative example 3 has no citric acid, sodium citrate and citronella oil, and loses the compounding effect of the citric acid, the sodium citrate, the citronella oil and the octaglycerol stearic acid, so that the bacteriostatic ability of the octaglycerol stearic acid is not improved better. In the embodiment 1, the citric acid and the sodium citrate are used as the buffering agent, and the plant essential oil is further added, so that the degreasing power is improved, the antibacterial, insect-repellent and mosquito-proof effects are increased,
the performance of the cleaning, disinfecting, skin-protecting and mosquito-preventing agent is detected as follows:
(1) oil removal rate and dirt-removing power
The cleaning functions of the cleaning, disinfecting, skin-protecting and mosquito-preventing agents obtained in the embodiments 1, 3, 4, 5 and 6 of the present invention are tested according to the arbitration method of one of the detection methods of the national standard GB9985-2000 in the above examples, so as to examine the cleaning and stain removal capabilities of the cleaning, disinfecting, skin-protecting and mosquito-preventing agents of the present invention.
Wherein the standard detergent is a detergent prepared according to a formula specified in the arbitration method of GB9985-2000, the oil removal rate of the standard detergent is 29.20%, and the detergency is defined as 1.
TABLE 1 list of cleaning and soil-removing ability test data of examples
Figure RE-GDA0002743851520000091
Figure RE-GDA0002743851520000101
As can be seen from the data in Table 1, compared with a standard detergent, the oil removal rate and the detergency of the cleaning, disinfecting, skin-protecting and mosquito-preventing agent disclosed by the invention are remarkably improved, the average oil removal rate can reach 39.45%, and the average detergency can reach 1.42, so that the cleaning, disinfecting, skin-protecting and mosquito-preventing agent disclosed by the invention is good in oil removal and detergency effect and good in cleaning function. In the comparative example, the compound action of citric acid, sodium citrate, citronella oil and octaglycerol stearic acid is lacked, so that the oil removal and decontamination capability of the detergent are reduced.
(2) Scratch-proof and antifogging performance
The anti-scratch and anti-fog functions of the cleaning, disinfecting, skin-protecting and anti-mosquito agents obtained in the examples 1, 2 and 3 of the invention are detected by the quick hot fog method which is one of three methods of the cold fog method, the quick hot fog method and the water bath hot fog method in the example according to the antifogging test method of the plastic film/sheet in the national standard GB \ T31726-2015, and the test results of the examples are shown in Table 3.
The scratch-proof antifogging agent for the spectacle lens reports the experimental grade according to a rapid hot fogging method of the antifogging standard of a plastic film in the national standard, and the judgment basis of the experimental grade is shown in a table 2.
Table 2 antifogging grade judgment criteria list

TABLE 3 tabulation of scratch and fog resistance test results for the examples
Figure RE-GDA0002743851520000111
As can be seen from the data in tables 2 and 3, the scratch-proof and antifogging properties of the cleaning, disinfecting, skin-protecting and mosquito-repellent agent are all 1 grade through detection, and after the lens is scratched by fingers for multiple times and is subjected to water bath, the lens is still completely transparent after being wiped, or the repeated test results after dilution are all 1 grade, so that the scratch-proof and antifogging properties are good.
(3) Bacteriostatic and bactericidal function
Example 1 was tested according to national standard GB.19877.1-2005 for a specific hand sanitizer, and the results are shown in Table 4 below:
TABLE 4 physicochemical standards for hygiene of the particular hand lotions and the results of the tests of the examples
Figure RE-GDA0002743851520000112
Figure RE-GDA0002743851520000121
TABLE 5 microbiological indicator of the Special hand lotions and test results of the examples
Figure RE-GDA0002743851520000122
As shown in the above tables 4 and 5, the physicochemical and sanitary conditions of the cleaning, disinfecting, skin-protecting and mosquito-repellent agent completely meet the physicochemical and sanitary condition standards of the national standard GB.19877.1-2005 special hand sanitizer. Meanwhile, the antibacterial rate of the cleaning, disinfecting, skin-protecting and mosquito-preventing agent is as high as 95%, the bacteriostatic rate is as high as 98%, the cleaning, disinfecting, skin-protecting and mosquito-preventing agent has high-efficiency degreasing, antibacterial and bacteriostatic functions, and the antibacterial and bacteriostatic effects of the comparative example are obviously weaker than those of the cleaning, disinfecting, skin-protecting and mosquito-preventing agent in the embodiment.
In conclusion, the multiple beneficial effects of the cleaning, disinfecting, skin-protecting and mosquito-preventing agent are emphasized in the following aspects:
1. in the aspect of cleaning and disinfection, the cleaning, disinfection and skin care cleanser has high cleaning power on hand heavy oil dirt (various mechanical lubricating oil and edible oil), and simultaneously has obvious effects on removing heavy metals in hand disinfection hand oil dirt and removing peculiar smell of unpleasant oil.
2. The antibacterial and degerming skin care product has the functions of regulating and protecting the pH of the skin when daily skin is washed by hands or body wash or is contacted with the skin for cleaning, and also has the functions of moisturizing and whitening the skin.
3. When the spectacle lens is clean, the spectacle lens has the functions of preventing scratching and fogging of the spectacle lens and preventing the automobile glass from fogging.
4. In the aspect of expelling insects and preventing mosquitoes, the skin after being smeared has the effects of preventing mosquitoes and protecting the skin, and has the function of preventing mosquitoes in the environmental space.
5. The cleaning aspect of dirt formed by the fatty protein on the collar, the cuffs and the like of clothes is also obvious!
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be taken as limiting the invention, so that any modifications, equivalents, improvements and the like, which are within the spirit and principle of the present invention, should be included in the scope of the present invention.
