摘要:
A dental care product comprising carbonate- substituted strontium-hydroxyapatite particles having a lactoferrin-functionalized surface, wherein said particles have the formula: Ca (10-x) Sr x (ΡO 4 ) (6-γ) (CO 3 ) y (OH) 2 wherein x is a number comprised between 0.0010 and 0.015; and y is a number comprised between 0.0010 and 0.010; and wherein said carbonate-substituted strontium-hydroxyapatite particles have a crystallinity degree CD comprised between 55 and 85%. The carbonate-substituted strontium-hydroxyapatite particles are biomimetic for composition, structure and morphology allowing a strong chemical affinity with natural enamel and dentine hydroxyapatite crystals and inducing the formation of a rimineralizing and protective surface coating on enamel and dentine.
摘要:
The present invention refers to oral care and oral hygiene products having photocatalytic activity comprising particles of a calcium phosphate compound, superficially functionalised with Ti02 nanoparticles in crystalline form, said Ti02 nanoparticles having: a) a substantially lamellar morphology; b) an aspect ratio (AR) comprised between 5 and 30; c) a surface structure having face (001) as outermost face of the crystalline lattice; and d) wherein the Ti02 is in the form of anatase, optionally mixed with rutile and/or brookite.
