Abstract

The present invention relates to a cosmetic composition comprising: (i) boron nitride; and (ii) one or more kinds of inorganic powders selected from the group consisting of cerium oxide, titanium oxide, talc, aluminum oxide, iron oxide, zinc oxide and mica. UVA, UVB and near-IR may be simultaneously screened by applying the cosmetic composition.

Claims

exact text as granted — not AI-modified
1 . A cosmetic composition comprising:
 (i) boron nitride; and   (ii) one or more kinds of inorganic powders selected from the group consisting of cerium oxide, titanium oxide, talc, aluminum oxide, iron oxide, zinc oxide and mica.   
     
     
         2 . The cosmetic composition according to  claim 1 , wherein boron nitride powder has an average particle size of 1-10 μm. 
     
     
         3 . The cosmetic composition according to  claim 1 , wherein boron nitride powder is present in an amount of 0.1-30 wt % based on the total weight of the composition. 
     
     
         4 . The cosmetic composition according to  claim 1 , wherein one or more kinds of inorganic powders selected from the group consisting of cerium oxide, talc, aluminum oxide, iron oxide, zinc oxide and mica have an average particle size of 0.1-40 μm. 
     
     
         5 . The cosmetic composition according to  claim 1 , wherein titanium oxide powder has an average particle size of 1-50 nm. 
     
     
         6 . The cosmetic composition according to  claim 1 , wherein cerium oxide powder is present in an amount of 0.1-30 wt % based on the total weight of the composition. 
     
     
         7 . (opowder is present in an amount of 5-25 wt % based on the total weight of the composition. 
     
     
         8 . The cosmetic composition according to  claim 1 , wherein talc powder is present in an amount of 0.1-10 wt % based on the total weight of the composition. 
     
     
         9 . The cosmetic composition according to  claim 1 , wherein aluminum oxide powder is present in an amount of 3-15 wt % based on the total weight of the composition. 
     
     
         10 . The cosmetic composition according to  claim 1 , wherein iron oxide powder is present in an amount of 0.001-5 wt % based on the total weight of the composition. 
     
     
         11 . The cosmetic composition according to  claim 1 , wherein zinc oxide powder is present in an amount of 1-20 wt % based on the total weight of the composition. 
     
     
         12 . The cosmetic composition according to  claim 1 , wherein mica powder is present in an amount of 0.1-10 wt % based on the total weight of the composition. 
     
     
         13 . The cosmetic composition according to  claim 1 , which blocks out UV and near-IR simultaneously. 
     
     
         14 . A method for blocking out UV and near-IR simultaneously comprising administering an effective amount of the composition according to  claim 1  to a subject in such need, wherein the method is for blocking out UV and near-IR simultaneously.
