Long-lasting liquid color compositions

Abstract

Embodiments include a liquid colorant composition having an acrylates/octylacrylamide copolymer, a cellulose material, alcohol and a colorant. The cellulose material may be hydroxypropylcellulose. Isostearyl alcohol and silica may be included in the composition to enhance properties such as the spreadability and feel of the composition on the lips. Additional additives such as fragrance and botanical extracts may also be added. Such compositions can be easily applied to the lips and offer long wear characteristics.

         6 . A lipstick as in  claim 1 , wherein said acrylate/methacrylate component comprises at least one material selected from the group consisting of isobutyl methacrylate, butyl acrylate, and methyl methacrylate.  
     
     
         7 . A lipstick as in  claim 1 , wherein said N-substituted acrylamide component comprises at least one material selected from the group consisting of t-octylacrylamide and t-butylacrylamide.  
     
     
         8 . A lipstick as in  claim 1 , wherein said N-substituted acrylamide component comprises t-octylacrylamide.  
     
     
         9 . A liquid lipstick as in  claim 1 , further comprising silica.  
     
     
         10 . A liquid lipstick as in  claim 1 , wherein said cellulose material comprises hydroxypropylcellulose.  
     
     
         11 . A lipstick as in  claim 1 , wherein said lipstick comprises approximately 0.5 to approximately 10 weight percent of said copolymer and approximately 0.1 to approximately 5.0 weight percent hydroxypropylcellulose.  
     
     
         12 . A lipstick as in  claim 11 , further comprising: 
 0.1 to 5 weight percent methyl glucose ether;    0.1 to 20 weight percent isostearyl alcohol;    0.1 to 10 weight percent silica;    up to 10 weight percent fragrance; and    up to 10 weight percent botanical extracts.    
     
     
         13 . A lipstick as in  claim 12 , comprising 0.5 to 4.5 weight percent methyl glucose ether, 2 to 4 weight percent isostearyl alcohol, and 1 to 2 weight percent silica.  
     
     
         14 . A liquid composition for coloring skin comprising: 
 an copolymer consisting essentially of 10-75% by weight acrylate/methacrylate, 10-70% by weight N-substituted acrylamide and 5-40% by weight unsaturated carboxylic acid;    a thickener material;    alcohol; and    colorant.    
     
     
         15 . A liquid composition as in claim  21 , wherein said thickener material comprises hydroxypropylcellulose.  
     
     
         16 . A liquid composition as in  claim 14 , wherein said alcohol comprises isostearyl alcohol and isopropyl alcohol.
