Abstract:
Multilayer material comprising a paper substrate on which at least one regenerated cellulose layer is applied, wherein the bonding between the paper substrate and the regenerated cellulose layer is achieved by means of a water-based adhesive and the regenerated cellulose layer comprises, as a surface coating, at least one layer of a material having the function of a barrier to the penetration of water. The resulting multilayer essentially consists only of materials based on cellulose or derivatives thereof, so it is suitable for manufacturing completely biodegradable disposable articles that can be collected separately as paper and recycled.
Abstract:
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.
Abstract:
A dental care product comprising carbonate-substituted fluoro-hydroxyapatite particles having the formula: Ca (10-x-y-m) Zn x Sr y M m (PO 4 ) (6-z) (CO 3 ) z (OH) 2-w F w wherein M is selected from the group comprising Mg, Se, K and mixtures thereof; x is a number comprised between 0 and 0.02; y is a number comprised between 0.0010 and 0.015; m is a number between 0 and 0.5; z is a number comprised between 0.0010 and 0.010 and w is a number comprised between 0.000002 and 0.0001; wherein said fluoro- hydroxyapatite particles have a crystallinity degree CD comprised between 50 and 85%.
