Abstract

The present disclosure provides a method of making a cosmetic brush head, having anti-aging ingredients infused therein. The method includes the steps of mixing anti-aging ingredients and synthetic grain, melting the mixture, extruding the mixture to form threads, stretching the threads to a desired thickness, shaping the threads, collecting the threads into a bundle, cutting the bundle, hanging the bundle, combing the bundle, wrapping the bundle, cutting the bundle into shorter bundles, soaking the bundles in a solution to form tapered tips on the threads, soaking the bundles in an anti-aging solution, unbundling the short bundles and randomizing the threads, sorting the threads, and recollecting and wrapping the threads into a brush size bundle. The method may further include shaping the brush size bundle to a desired brush shape and securing the bundle to form a cosmetic brush head.

Claims

exact text as granted — not AI-modified
1 . A method of making a cosmetic brush head comprising:
 forming a grain mixture from one or more anti-aging ingredients and at least one synthetic grain;   melting and extruding the grain mixture to form a plurality of filaments;   shaping and cutting the plurality of filaments;   collecting the plurality of filaments into bundles to form a brush bundle; and   affixing a brush bundle to a styling tool handle.   
     
     
         2 . The method of  claim 1 , wherein forming the grain mixture from the one or more anti-aging ingredients and the at least one synthetic grain includes forming the grain mixture from one or more antioxidants and at least one synthetic grain. 
     
     
         3 . The method of  claim 1 , wherein forming the grain mixture from the one or more anti-aging ingredients and the at least one synthetic grain includes forming the grain mixture from one or more of vitamin A, vitamin C, and vitamin E and at least one synthetic grain. 
     
     
         4 . The method of  claim 1 , wherein forming the grain mixture from the one or more anti-aging ingredients and the at least one synthetic grain includes forming the grain mixture from one or more of vitamin A, vitamin C, vitamin E, hydrolyzed collagen, niacin, peptides, antioxidants, and hydrolyzed silk and at least one synthetic grain. 
     
     
         5 . The method of  claim 1 , wherein forming the grain mixture from the one or more anti-aging ingredients and the at least one synthetic grain includes forming the grain mixture from one or more one or more anti-aging ingredients and polybutylene terephthalate. 
     
     
         6 . The method of  claim 1 , wherein forming the grain mixture from the one or more anti-aging ingredients and at the least one synthetic grain includes forming a grain mixture having a mixed ratio 1:100 anti-aging ingredients and the synthetic grain. 
     
     
         7 . The method of  claim 1 , further comprising:
 soaking the brush bundle in an anti-aging solution of at least one anti-aging ingredients.   
     
     
         8 . The method of  claim 7 , wherein soaking the brush bundle in the anti-aging solution of at least one anti-aging ingredients includes soaking the brush bundle in an anti-aging solution having ratio of 5:1 of solvent to anti-aging ingredients. 
     
     
         9 . The method of  claim 1 , wherein shaping and cutting the plurality of filaments includes stretching the filaments to a thickness in the range of 0.07 millimeters to 0.1 millimeters. 
     
     
         10 . The method of  claim 1 , wherein shaping and cutting the plurality of filaments includes crimping the filaments. 
     
     
         11 . The method of  claim 1 , wherein shaping and cutting the plurality of filaments includes forming tapered tips on a distal end of the plurality of filaments. 
     
     
         12 . The method of  claim 1 , wherein shaping and cutting the plurality of filaments includes tapering the distal ends of the filaments by etching. 
     
     
         13 . The method of  claim 12 , wherein shaping and cutting the plurality of filaments includes tapering the distal ends of the filaments by etching in a basic composition. 
     
     
         14 . The method of  claim 1 , further comprising dying the brush bundle.
