Composite material for use in tooth paste, bone-remineralizing compositions and implants contains a sparingly-soluble calcium salt, e.g. fluoride, in the form of nanoparticles and a protein component
Composite material for use in tooth paste, bone-remineralizing compositions and implants contains a sparingly-soluble calcium salt, e.g. fluoride, in the form of nanoparticles and a protein component
Calcium salts in the form of nano-scale primary particles with an average diameter of 10-300 nm are used in composite materials containing sparingly-soluble calcium salts (e.g. phosphates or fluorides) and a protein component. Composite materials (I) containing (a) calcium salts which are sparingly soluble in water, selected from phosphates, fluorides and fluorophosphates, which may also contain hydroxyl and/or carbonate groups, in the form of nano-scale primary particles with an average diameter of 10-300 nm and (b) proteins, protein hydrolysates and/or protein hydrolysate derivatives. Independent claims are also included for: (a) a process for the production of (I) by precipitation from aqueous solutions of water-soluble calcium salts and aqueous solutions of water-soluble phosphate and/or fluoride salts in presence of protein components; (b) toothpaste containing (I); (c) compositions containing (I) for inducing or promoting the renewed formation of bony tissue.
