preparation example Construction
[0038] The preparation method of above-mentioned embodiment 1-3, operate as follows:
[0039] (1) accurately take by weighing dipropylene glycol in emulsifying pot, add PEG-60 hydrogenated castor oil, peach phenol, farnesol, grapefruit seed extract and antibacterial flavoring agent successively, stir to obtain mixed solution A ;
[0040] (2) Heat the water to 95±1°C, keep the temperature for 5-10 minutes, then cool down to 30-35°C, add it to the emulsification pot, mix with the mixed solution A, stir evenly, and discharge and fill after passing the inspection.
[0041] The preparation method of Comparative Example 1-4 is the same as that of Example 1-3, except that the components with zero mass are not added.
[0042] The spray water preparation containing the natural bacteriostatic agent prepared in the above Examples 1-3 was tested for efficacy, including the irritation test, and the deodorant effect and the antibacterial effect were compared with those of Comparative Examp...
Embodiment 3
[0085] In the bacteriostatic test of Example 3, the total number of bacterial colonies was less than 10 cfu / g on the seventh day; the total number of mold and yeast colonies was 3.0×10 5 cfu / g reduced to 1.1×10 2 cfu / g, and <10 cfu / g by day 14, significantly lower than Comparative Examples 1-4. It shows that the antibacterial effect of grapefruit seed extract with farnesol, toritol and antibacterial flavoring agent is significant, which is obviously better than that of the same amount of single component (Comparative Examples 2-4), and better than grapefruit The combination of seed extract, farnesol and tortosol (Comparative Example 1). The four components can synergistically inhibit bacteria without increasing the dosage of a single component to improve the effect, and the effect of bacteriostasis and deodorization can be achieved with a low content ratio in the spray.
