The invention discloses an oral composition containing
polysaccharide-based
cinnamon oil antibacterial
Pickering emulsion and a preparation method thereof, and belongs to the technical field of oral care products. The composition comprises
Pickering emulsion and an orally acceptable carrier, wherein the
Pickering emulsion takes
cinnamon oil as a dispersion phase and
polysaccharide-based
solid particles as a
stable phase, and the content of the Pickering
emulsion is 20-60%; the
polysaccharide-based
solid particles are preferably
chitosan nano-particles of which the surfaces are modified in situ by polydopamine, the
emulsion is prepared by high-speed shearing and emulsifying, and the composition can be prepared into
toothpaste and
mouth wash. The Pickering
emulsion is constructed through polysaccharide-based particles, the problem that
cinnamon oil is easy to volatilize and degrade is solved, polydopamine in-situ modification endows the emulsion with excellent oral adhesion and
retention capacity,
saliva scouring and pH fluctuation can be resisted, and the long-acting effect of the cinnamon oil is achieved; meanwhile, the synergistic antibacterial and anti-
biofilm effect of the polysaccharide-based particles, the cinnamon oil and the polydopamine is achieved, the preparation process is simple, the method is matched with an existing oral care product production
system, and safety and industrialization feasibility are excellent.
