The invention discloses a bacteriostatic,
deodorant and
aroma-enhanced composite oral spray and a preparation method thereof. According to the compound oral spray disclosed by the invention, the
lactoferrin-iron
ion compound is prepared to be combined with the
sulfide, the
essential oil is compounded to improve breath, and the nano-
liposome is prepared, so that multi-mechanism synergistic deodorization and bacteriostasis are realized. The nano-
liposome entraps the globe
artichoke extract, the
tannic acid and the
zinc ion compound, and the
liposome realizes bacterial targeting by taking saccharides as an attractant, so that the activity of an
odor-producing
enzyme is inhibited, the generation of
sulfide is blocked, and the bacterial
cell structure is destroyed. According to the invention, rapid and lasting
oral cavity deodorization and bacteriostatic protection are realized through synergistic effect of three ways of combination of
odor substances, rapid deodorization, bacteriostasis and
enzyme activity inhibition. The stability is improved by adopting high-pressure homogenization and membrane
filtration processes, and the easily degradable active ingredients are encapsulated and protected by the lipidosome, so that the product is high in stability and lasting in activity.
