Indium tin oxide coated particles and compositions

Abstract

Anhydrous topical compositions containing a solid or hollow particle ranging from 0.001 to 200 microns in diameter coated with Indium Tin Oxide (“ITO”) and methods for protecting skin against IR (infrared) radiation by topically applying the anhydrous compositions.

1 . An anhydrous topical composition comprising a solid or hollow particle ranging from 0.001 to 200 microns in diameter coated with Indium Tin Oxide (“ITO”) in an amount sufficient to block IR radiation in the wavelength range of IR-A, IR-B, and IR-C and ranging from 760 to 1 mm. 
     
     
         2 . The composition of  claim 1  which is pigmented. 
     
     
         3 . The composition of  claim 1  in the form of a mascara, blush, foundation, face powder, concealer, or eye shadow. 
     
     
         4 . The composition of  claim 1  in the form of a solid stick or spray. 
     
     
         5 . A foundation makeup or powder composition with SPF comprising a solid or hollow particle ranging from 0.001 to 200 microns in diameter coated with Indium Tin Oxide (“ITO”), pigments, powders, and at least one chemical or physical sunscreen. 
     
     
         6 . The composition of  claim 5  wherein the composition is in the form of a pressed powder. 
     
     
         7 . The composition of  claim 5  wherein the composition is in the form of a foundation makeup comprising a volatile solvent, a silicone resin, and at least one oil. 
     
     
         8 . The composition of  claim 1  additionally comprising titanium dioxide. 
     
     
         9 . The composition of  claim 1  additionally comprising a powder which is white or non-pigmented. 
     
     
         10 . The composition of  claim 1  wherein the thickness of the ITO coating on the particle ranges from 0.1 to 1000 nanometers in thickness. 
     
     
         10 . The composition of  claim 1  wherein the ITO coated particle has a size ranging from 0.001 to 100 microns, which is titanium dioxide, zinc oxide, or mixtures thereof wherein the particle is operable to block IR and UV radiation. 
     
     
         11 . The composition of  claim 10  additionally containing titanium dioxide or zinc oxide. 
     
     
         12 . A method for protecting skin against IR radiation by topically applying the composition of  claim 1 .
