The cosmetic brush is subjected to weighing detection of the powder adhering amount and the powder releasing amount, and the calculation method is as follows:
the weight of the powder sticking (g) is the weight of the cosmetic brush after sticking powder (g) -the net weight of the cosmetic brush (g)
Amount of powder released (g) ═ weight of cosmetic brush after sticking powder (g) — weight of cosmetic brush after use (g)
And (3) testing antibacterial performance: the antibacterial properties of the cosmetic brushes obtained in examples 1 to 15 and comparative examples 1 to 5 were measured by the bacteria reduction rate;
the bacteria reduction rate is (B-A)/Bx 100%
Wherein A is the number of bacteria recovered from the test sample at the contact time of "1 h", and B is the number of bacteria recovered from the blank at the contact time of "0", and the bacteria were Staphylococcus aureus.
TABLE 2 test results of examples 1 to 16 and comparative examples 1 to 3
As can be seen by combining examples 1 to 16 and comparative examples 1 to 3 with table 2, the antibacterial ratio of the antibacterial filaments can be improved by surface-modifying the silver-loaded silica. The cosmetic brush prepared from the antibacterial fibril has the advantages of excellent powder adhering amount and powder releasing amount, large powder adhering amount and powder releasing amount, uniform facial cosmetic effect, strong skin-adhering feeling and good cosmetic effect. The antibacterial fibril has higher tensile strength and flexural modulus, and is tougher and softer, so that the cosmetic brush is more comfortable when contacting the skin. The antibacterial rate of the antibacterial agent is more than 79.1%, and the antibacterial agent has an excellent antibacterial effect.
From the test data of example 3 and examples 5-7, it can be seen that when the addition amount of the organosilicon modified nano silver-loaded titanium dioxide is gradually increased, the antibacterial rate of the antibacterial fibrils is gradually increased, but the powder adhesion amount and the powder release amount of the organosilicon modified nano silver-loaded titanium dioxide are in a trend of small and gradually reduced amplitudes.
The microcrystalline cellulose can improve the dispersibility of the organic silicon modified nano silver-loaded titanium dioxide, so that the antibacterial property of the antibacterial fibril can be improved under the condition of the same addition amount of the organic silicon modified nano silver-loaded titanium dioxide. It can be seen from the test data of example 6 and examples 8 to 11 that the antibacterial ratio of the antibacterial filaments gradually increases as the amount of microcrystalline cellulose added gradually increases within a certain range.
The organic silicon resin is organic silicon polymer, can improve the hydrophobicity of the antibacterial fibril, can enable the antibacterial fibril to have the moisture-proof function, and thus, the antibacterial rate of the antibacterial fibril is increased. As can be seen from the test data of example 3 and examples 13-14, the antibacterial rate increases with the addition of a certain amount of silicone resin.
It can be seen from the test data of examples 15 to 16 and comparative example 3 that the amount of adhering powder and the amount of releasing powder gradually decrease as the diameter of the antibacterial filament gradually increases within a certain range.
From the test data of example 3, example 13 and comparative example 2, it can be seen that when the dispersibility of the silicone resin and the silicone-modified nano silver-loaded titanium dioxide is added alone, the antibacterial rate is lower than that when the dispersibility of the silicone resin and the silicone-modified nano silver-loaded titanium dioxide are added simultaneously, indicating that the two have a synergistic effect.
The present embodiment is only for explaining the present application, and it is not limited to the present application, 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 application.
