Test one: sterilization test
Test samples: examples 1 to 16 and comparative examples 1 to 9 were selected as test samples.
The test method comprises the following steps:
1. the appearances of examples 1 to 16 and comparative examples 1 to 9 were observed, and it was found that each of examples 1 to 16 and comparative examples 1 to 8 had a uniform texture in which no precipitation occurred; in contrast, comparative example 9 had a non-uniform texture and slightly precipitated.
2. Firstly, fresh slant culture of Escherichia coli, Staphylococcus aureus and Candida albicans cultured for 18h is washed by tryptone-containing diluent to prepare test bacterial suspension, 1ml of test bacterial suspension is dripped on a sterile glass slide, and the test bacterial suspension is naturally air-dried to prepare a bacterial slide.
3. Fully mixing water and the bacteria tablet in the embodiment 1 according to the mass ratio of 50: 1, completely immersing the bacteria tablet in the water, standing for 15min, taking out the bacteria tablet, putting the bacteria tablet into a test tube containing 5.0ml of neutralizing agent, neutralizing for 10min, washing the bacteria on the bacteria tablet, counting the viable bacteria, and calculating the sterilization rate of the embodiment 1.
4. Examples 2-16, comparative examples 1-9 were tested in the same test manner as example 1, and the sterilization rate was recorded and analyzed together with the sterilization rate of example 1. And three replicates of each test sample were used.
And (3) test results: the sterilization rates of examples 1 to 16 and comparative examples 1 to 9 in 15min are shown in Table 3.
TABLE 3 Sterilization rates within 15min for examples 1-16 and comparative examples 1-9
As can be seen from Table 3, the sterilization rates of examples 1-16 against Escherichia coli, Staphylococcus aureus and Candida albicans were all higher than those of comparative examples 1-9 against Escherichia coli, Staphylococcus aureus and Candida albicans.
Among them, examples 13 to 14 were slightly inferior to the other examples in the sterilization rate, mainly because the composition of the anti-association component was changed, resulting in a decrease in the sterilization rate.
In comparative examples 1 to 8, the sterilization rate was reduced due to the presence of different degrees of component deletion or dosage falling outside the proper range among the anti-association component, the high-strength surfactant, the tea tree essential oil, and the PEG-40 hydrogenated castor oil.
Further, in comparative examples 5 to 8, since the castor oil and potassium hydroxide in the anti-association component were not in the proper amount range, the possibility of preventing association of parachlorometaxylenol was reduced, and thus, it was demonstrated that the amounts of castor oil and potassium hydroxide in the anti-association component were very critical, and if not in the proper range, the sterilization rate was very low.
And (2) test II: fabric cleaning test
Test samples: examples 1 to 16 and comparative examples 1 to 9 were selected as test samples.
Test subjects: the selected materials are the same and have the area of 1m2And 5ml of the same hero brand black ink was sprayed onto the cloth as the test object.
The test method comprises the following steps: 250 pieces of the above cloth (ink dried) were produced and divided into 25 groups on average, 10 pieces for each group, and the 1 st to 16 th groups were cleaned by examples 1 to 16, respectively, and the 17 th to 25 th groups were cleaned by comparative examples 1 to 9, respectively. The test was carried out in the same washing machine, the washing time was 5min, the cloth was taken out and rinsed, and the washing of 25 groups of cloth was observed and recorded.
And (3) spraying ink and cleaning again by adopting the method in the second test, repeating the operation for 100 times, and observing and recording the cleanliness and the softness of 25 groups of cloth.
And (3) test results: the cleaning of the 25 cloth groups is shown in table 4.
TABLE 3 Sterilization rates within 15min for examples 1-16 and comparative examples 1-9
As can be seen from Table 4, the cloth materials of groups 1 to 16 of examples 1 to 16 were clean and free from ink residue, indicating strong stain removal; after 100 times of repeated washing, the cloth of groups 1-16 still has soft hand and fluffy texture, which shows that the cloth of examples 1-16 can be protected from being damaged and the hardening of the cloth caused by the calcium and magnesium ions in water attached on the cloth can be reduced when the excellent dirt-removing capacity is achieved.
With the cloth of group 17 of comparative example 1, although it was washed clean and no ink remained, the hand of the cloth became hard and non-fluffy after 100 times of repeated washing, indicating that the stain-removing ability of comparative example 1 was good, but it was difficult to prevent calcium and magnesium ions in water from adhering to the cloth during the washing process, thereby causing a case where the cloth became hard.
With the fabrics of groups 18-24 of comparative examples 2-8, the cleaning was not clean enough, ink remained, and after 100 repeated washes, the hand of the fabric was hard and did not become fluffy. The reasons for this are mainly: in comparative example 2, the strong surfactant was replaced, and the anti-association component, tea tree essential oil, and PEG-40 hydrogenated castor oil were not present, which not only reduced the detergency, but also damaged the fabric, and did not feel as good as it was. In comparative example 3, tea tree essential oil and PEG-40 hydrogenated castor oil were not used, resulting in poor cleaning and damage to the cloth. In comparative example 4, the use amounts of the strong surfactant, the anti-association component, the tea tree essential oil, and the PEG-40 hydrogenated castor oil were out of the appropriate ranges, which not only resulted in poor detergency of comparative example 4, but also damaged the cloth. In comparative examples 5 to 8, the castor oil and potassium hydroxide were not added in the proper ratio, resulting in association of the parachlorometaxylenol with the surfactant, resulting in the influence on the detergency of comparative examples 5 to 8.
The cloth of group 25 of comparative example 9 was cleaned cleanly with some ink residue, but after 100 repeated washings the cloth felt slightly stiff and not fluffy enough, indicating that the preparation method would adversely affect the stain removal ability of the test sample obtained and its protection of the cloth.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.
