  • Metal-carbon structure hybrid formulation for dental use in the treatment of dental hypersensitivity, demineralization and cavities
    Patent number: 11071697
    Abstract: The present invention relates to an antibacterial composition which, when applied to the surface of a tooth, allows remineralisation of the enamel to occur, said composition having very low toxicity for human use. When applied, the composition leaves no stains and does not alter the visible colour characteristics of the teeth to which it has been applied.
    Type: Grant

  • Polymeric materials with antifouling, biocidal, antiviral and antimicrobial properties; elaboration method and its uses
    Patent number: 9481800
    Abstract: The present invention is related to polymeric materials, in particular thermoplastic or resins, with antifouling, biocidal, antiviral and antimicrobial properties. In particular, the present invention comprises a polymeric material with antimicrobial properties, wherein said antimicrobial property is given by the controlled and maintained in time release of elements or compounds with antimicrobial properties. The present invention also relates to the preparation method and products generated from said polymeric materials with antimicrobial properties.

  • ADDITIVE THAT CONFERS BIOCIDAL PROPERTIES TO DIFFERENT MATERIALS, SUCH AS NATURAL OR SYNTHETIC, THERMOPLASTIC OR THERMOSTABLE, POLYMERIC RESINS, ORGANIC COATINGS, PAINTINGS, VARNISHES, LACQUERS, COATINGS, GELS, OILS, WAXES, CERAMICS, AMONG OTHERS
    Publication number: 20160150793
    Abstract: The present invention is related to an additive with biocidal properties based on an active agent with antimicrobial and antifouling properties, wherein the additive corresponds to a supporting material, inert substrate or carrier, which has been modified with antimicrobial agents. The invention further describes the method for modifying the supporting material, inert substrate or carrier, with antimicrobial agents. The resulting additives have a biocidal activity, and can be incorporated in different matrices, such as polymeric resins, either natural or synthetic, thermoplastic or thermostable, organic coatings, ceramics, paintings, varnishes and coatings, granting biocidal activity to those matrices.
