Abstract
Generally regarded as safe (GRAS) dyes can be used as photosensitizing dyes in oral compositions to provide anti-bacterial and anti-inflammatory efficacy. Embodiments include oral care compositions including photosensitizing dyes, methods of making the compositions, methods of using the compositions, and kits containing the compositions and light emitting devices.
Claims29
A method of treating conditions caused by microorganisms comprising irradiating an area of the oral cavity suspected of containing microorganisms with visible light at a wavelength from 380 nm to 780 nm, at a dosage of from 1 J/cm2 to 450 J/cm2, with a power density of from about 1 to about 500 mW/cm2, and for a period of time of from 1 second to 120 minutes.
A method of treating conditions caused by microorganisms comprising:
- a) administering an oral care composition comprising at least one photosensitizing dye to an area of the oral cavity suspected of containing microorganisms, wherein the photosensitizing dye is selected from the group consisting of Chlorophyllin sodium copper salt, Tartrazine (FD&C Yellow No. 5), Riboflavin 5′-monophosphate sodium salt, Allura Red AC (FD&C Red No. 40), New Coccine (CI 16255, Food Red 7), Chromotrope FB (CI 14720, Food Red 3), Indigo Carmine, Erioglaucine disodium salt (FD&C Blue No. 1), Fast Green FCF (FD&C Green No. 3), Lissamine Green B, Napthol Green or Acid Green, Cochineal, Carmoisine azorubine, Amaranth, Brillant Scarlet 4R, copper complexes of chlorophylls, Brillant black BN(PN), Chocolate Brown HT, Beta-carotene, Bixin, Lycopene, Betanin, Erythrosin B sodium salt, and mixtures thereof;
- and
- b) irradiating the area to which the composition is administered with light at a wavelength absorbed by the at least one photosensitizing dye.
An oral care composition comprising at least one photosensitizing dye for use in a method of treating conditions caused by microorganisms, the method comprising
- a) administering the oral care composition to an area of the oral cavity suspected of containing microorganisms, wherein the photosensitizing dye is selected from the group consisting of Chlorophyllin sodium copper salt, Tartrazine (FD&C Yellow No. 5), Riboflavin 5′-monophosphate sodium salt, Allura Red AC (FD&C Red No. 40), New Coccine (CI 16255, Food Red 7), Chromotrope FB (CI-14720, Food Red 3), Indigo Carmine, Erioglaucine disodium salt (FD&C Blue No. 1), Fast Green FCF (FD&C Green No. 3), Lissamine Green B, Napthol Green or Acid Green, Cochineal, Carmoisine azorubine, Amaranth, Brillant Scarlet 4R, copper complexes of chlorophylls, Brillant black BN(PN), Chocolate Brown HT, Beta-carotene, Bixin, Lycopene, Betanin, Erythrosin B sodium salt, and mixtures thereof;
- and
- b) irradiating the area to which the composition is administered with light at a wavelength absorbed by the at least one photosensitizing dye.
