Mascara brush with small diameter bristle fibers

Abstract

A mascara applicator system for a low viscosity mascara product a having a viscosity of 120,000 centipoise or less is a twisted wire mascara brush containing bristles having a relatively small diameter and relatively high bristle density. The bristles have a diameter of from 0.0001 inch to about 0.004 inch, preferably 0.0005 inch to 0.003 inch, and most preferably 0.001 to 0.003 inch. The bristle density is in the range of 18-175 bristles per turn; depending on the bristle diameter.

1 . A mascara application system, comprising: 
 a brush for applying mascara to eyelashes having a twisted wire core holding a plurality of radially extending bristles to form a brush at an end of the core, said bristles having a diameter, said bristles being provided at a bristle density, said bristle density range being selected dependent on the bristle diameter, wherein if said bristles have a diameter of about 0.0001 inch to 0.00049 inch said bristle density is 200-60 bristles per turn, and if said bristles have a diameter of about 0.0005 inch to 0.00099 inch said bristle density is 180-40 bristles per turn, and if said bristles have a diameter of about 0.001 inch to 0.0019 inch said bristle density is 175-30 bristles per turn, and if said bristles have a diameter of about 0.002 inch to 0.0029 inch said bristle density is 120-22 bristles per turn; and    a lower viscosity mascara product having a viscosity of 120,000 centipoise or less provided on said brush.    
   
   
       2 . The mascara application system of  claim 1 , wherein the bristles have a diameter of about 0.0001 inch to 0.00049 inch and a bristle density of 200-60 bristles per turn.  
   
   
       3 . The mascara application system of  claim 1 , wherein the bristles have a diameter of about 0.0005 inch to 0.00099 inch and a bristle density of 180-40 bristles per turn.  
   
   
       4 . The mascara application system of  claim 1 , wherein the bristles have a diameter of about 0.001 inch to 0.0019 inch and a bristle density of 175-30 bristles per turn.  
   
   
       5 . The mascara application system of  claim 1 , wherein the bristles have a diameter of about 0.002 inch to 0.0029 inch and a bristle density of 120-22 bristles per turn.  
   
   
       6 . The mascara application system of  claim 1 , wherein said mascara product has a viscosity of viscosity in the range of about 7000 to about 120,000 centipoise at 25 degrees C.  
   
   
       7 . A mascara application system, comprising: 
 a brush for applying mascara to eyelashes having a twisted wire core holding a plurality of radially extending bristles to form a brush at an end of the core, said bristles having a diameter, said bristles being provided at a bristle density, said bristle density range being selected dependent on the bristle diameter, wherein if said bristles have a diameter of about 0.0001 inch to 0.00049 inch said bristle density is 200-60 bristles per turn, and if said bristles have a diameter of about 0.0005 inch to 0.00099 inch said bristle density is 180-40 bristles per turn, and if said bristles have a diameter of about 0.001 inch to 0.0019 inch said bristle density is 175-30 bristles per turn, and if said bristles have a diameter of about 0.002 inch to 0.0029 inch said bristle density is 120-22 bristles per turn; and    a mascara product, having a viscosity in the range of about 7000 to about 120,000 centipoise at 25 degrees C., provided on said brush.    
   
   
       8 . The mascara application system of  claim 7 , wherein the bristles have a diameter of about 0.0001 inch to 0.00049 inch and a bristle density of 200-60 bristles per turn.  
   
   
       9 . The mascara application system of  claim 7 , wherein the bristles have a diameter of about 0.0005 inch to 0.00099 inch and a bristle density of 180-40 bristles per turn.  
   
   
       10 . The mascara application system of  claim 7 , wherein the bristles have a diameter of about 0.001 inch to 0.0019 inch and a bristle density of 175-30 bristles per turn.  
   
   
       11 . The mascara application system of  claim 7 , wherein the bristles have a diameter of about 0.002 inch to 0.0029 inch and a bristle density of 120-22 bristles per turn.
