Efficacy testing

1. In order to verify the degerming effect of the antibacterial and deodorant air freshener, the following steps are adopted,

(1) the air freshener prepared in the example 1 is adopted to respectively act on escherichia coli, staphylococcus aureus and candida albicans for 3min, 6min, 9min and 12 min;

(2) the air freshener prepared in the comparative example 1 is adopted to respectively act on escherichia coli, staphylococcus aureus and candida albicans for 3min, 6min, 9min and 12 min;

(3) adopting the air freshener prepared in the comparative example 2 to respectively act on escherichia coli, staphylococcus aureus and candida albicans for 3min, 6min, 9min and 12 min;

(4) the sterilization of each bacterium was observed by a microscope, and the evaluation results are shown in tables 1 to 3.

TABLE 1

TABLE 2

TABLE 3

From the above evaluation results, it can be seen that the air freshener of the present invention has better sterilization effects on escherichia coli, staphylococcus aureus and candida albicans, while comparative examples 1 and 2 have no sterilization function as the present invention. Therefore, the optimal sterilization effect can be obtained only by simultaneously adopting dodecamethylpentasiloxane, 3-methoxy-3-methyl-1-butanol, compound quaternary ammonium salt, solvent (formed by a mixture of polyaminopropyl methylsiloxane at methoxy end and acetone glycerin), essence, propellant and air freshener; whereas, the absence of a solvent (a mixture of methoxy-terminated polyaminopropylmethylsiloxane and glycerol acetonide) or the absence of dodecamethylpentasiloxane does not maintain a high level of sterilization efficacy. It can be seen that the solvent (the methoxy-terminated polyaminopropylmethylsiloxane mixture and the glycerol acetonide) and the dodecamethylpentasiloxane have a synergistic effect, as long as when both are used together, the bactericidal component dodecamethylpentasiloxane takes advantage of its better dissolution function in the solvent of the present invention, the solvent can form a coating on the surface of the part, and the solvent (the methoxy-terminated polyaminopropylmethylsiloxane mixture and the glycerol acetonide) and the dodecamethylpentasiloxane promote each other, thereby achieving an excellent bactericidal effect.
