| 2.0-6.0 | Moderate irritation |
| 6.0-8.0 | Strong irritation |
The results show that: no edema condition appears in the rabbits coated with the no-clean disinfectant of the embodiments 1-5 of the invention after 14 days, only individual mice of a group of rabbits have slight erythema symptom, and the average of the final erythema forming score is 0.1, and is in the score range of 0.0-0.5, which is nonirritating, so the no-clean disinfectant of the invention is safe and nonirritating, and the skin can not be damaged even if the no-clean disinfectant is used for a long time. The final stimulation total scores of the control group 1 and the control group 2 were 0.6 and 0.9, respectively, and were both in the range of 0.5-2.0, which were mild irritations, and the skin was likely to be slightly damaged by long-term use.
(III) test of air drying Effect
Effect test: the results of the tests were compared with those of the above examples 1 to 5 and the control groups 1 to 2.
The experimental control conditions and procedures were as follows:
140 volunteers aged 25-30 years, 70 males and 70 females, were selected at the same time in the same area and randomly divided into 7 groups of 20 individuals. In a closed windless environment at the same time in the same indoor place, each volunteer can quickly and uniformly smear 5ml of the no-clean disinfectant of the corresponding group on the hand, naturally flatten the palm, test the time for air drying, and record the time. Then, in the same outdoor place and at the same time, in an unobstructed open flat land without direct sunlight or strong wind, all groups of volunteers face the wind direction, each volunteer is quickly and uniformly smeared on the hand by using 5ml of the no-clean disinfectant of the corresponding group, then the palm is naturally flattened, the time for air drying is tested, and the record is carried out; test data and information conditions are summarized, and the average air drying time of different fields in each group is calculated, and the result is shown in the attached figure 3.
It is obvious from the data and the comparison result of the column-shaped conditions in the attached figure 3 that, compared with the non-washing disinfectant prepared by the comparison group 1 according to the published patent formula and the preparation method and the conventional product disinfectant purchased in the comparison group 2 on the market, the non-washing disinfectant obtained in the embodiments 1-5 of the present invention has extremely high volatilization speed, the average air drying speed used indoors reaches 14.64-16.10 seconds, the average air drying speed used outdoors can reach 8.91-10.06 seconds, and the effect of quickly reaching the air drying state is provided, so that the uncomfortable feeling of wet hand or sticky hand can not be caused, and the use feeling is better. The average indoor air drying speed of the no-clean disinfectant of the comparison group 1-2 after use is over 27.31 seconds, the average outdoor air drying speed is over 19.25 seconds, and the air drying speed both outdoors and indoors is obviously slower than that of the embodiment 1-5, so that the no-clean disinfectant consumes longer time, is not beneficial to touching other objects by hands of users, causes much inconvenience and has poor use feeling.
By integrating the antibacterial and bacteriostatic effect detection, multiple irritation tests and the use air drying effect test, the no-clean disinfectant obtained in the embodiments 1-5 of the invention has obvious antibacterial and bacteriostatic effects, is mild in components, does not cause damage to skin even if used for a long time, is excellent in volatility, has a quick air drying effect, is more convenient and comfortable to use, and is suitable for popularization and application.
The above description is only for the purpose of illustrating the embodiments of the present invention and not for the purpose of limiting the same, and equivalent modifications and variations of the embodiments of the present invention will be apparent to those skilled in the art without departing from the overall spirit of the invention.
