Antioxidant compositions and methods of protecting skin, hair and nails against high energy blue-violet light

Abstract

Compositions and methods of using them for protecting skin, hair and nails against exposure to high energy visible light are described. The compositions can include one or more natural oils or extracts which are effective to absorb the high energy visible light at least to some degree.

         71 . A composition comprising:
 at least one natural oil or extract present in an effective amount to provide a HEV/VIS ratio of greater than or equal to 1.5 at an area of an animal where the composition has been topically administered; and   a carrier combinable with the natural oil or extract to permit topical application of the natural oil or extract to the skin, hair or nails.   
     
     
         72 . The composition of  claim 71 , in which the natural oil or extract and its concentration is present in an effective amount to provide a HEV/VIS ratio of at least 1.75. 
     
     
         73 . The composition of  claim 71 , in which the natural oil or extract and its concentration is present in an effective amount to provide a HEV/VIS ratio of at least 2.0. 
     
     
         74 . The composition of  claim 71 , in which the natural oil or extract and its concentration is present in an effective amount to provide a HEV/VIS ratio of at least 2.25. 
     
     
         75 . The composition of  claim 71 , further comprising two natural oils or extracts or their combination, wherein the two natural oils or extracts are each present in an effective amount to provide a HEV/VIS ratio of at least 1.5 for the composition. 
     
     
         76 . The method of  claim 75 , in which the two natural oils or extracts or their combination and their concentrations are selected to provide a HEV/VIS ratio of at least 2.0 for the composition. 
     
     
         77 . The composition of  claim 71 , further comprising at least three natural oils or extracts or their combination, wherein the three natural oils or extracts are each present in an effective amount to provide a HEV/VIS ratio of at least 1.5 for the composition. 
     
     
         78 . The composition of  claim 77 , in which the three natural oils or extracts or their combination and their concentrations are selected to provide a HEV/VIS ratio of at least 2.0 for the composition. 
     
     
         79 . The composition of  claim 71 , in which the composition comprises at least four natural oils or extracts or their combination each present in an effective amount to provide a HEV/VIS ratio of at least 1.5 or at least 2.0 for the composition. 
     
     
         80 . The composition of  claim 71 , further comprising at least one of (i) an additional component effective to absorb incident light having a wavelength below 380 nm, (ii) a booster effective to reduce reactive oxygen species or (iii) particles effective to scatter light comprising a wavelength of about 380 nm to about 500 nm. 
     
     
         81 . A composition comprising:
 at least one natural oil or extract, wherein the natural oil or extract is present in an effective amount in the composition to reduce reactive oxygen species in an external animal cell by at least 10% after topical application of the composition to the external animal cell, and wherein the composition comprises an effective amount of the oil to provide a HEV/VIS ratio of at least 1.5 where the composition has been topically applied; and   a carrier combinable with the natural oil or extract to permit topical application of the natural oil or extract to the external animal cell.   
     
     
         82 . The composition of  claim 81 , in which the natural oil or extract and its concentration is present in an effective amount to provide a HEV/VIS ratio is at least 1.75. 
     
     
         83 . The composition of  claim 81 , in which the natural oil or extract and its concentration is present in an effective amount to provide a HEV/VIS ratio is at least 2.0. 
     
     
         84 . The composition of  claim 81 , in which the natural oil or extract and its concentration is present in an effective amount to provide a HEV/VIS ratio is at least 2.25.
