Fast Bonding Hair/Eyelash Extension Adhesive Compositions Based On Medical Grade High Viscosity Cyanocrylates

Abstract

A fast-bonding and long-lasting adhesive composition with a high viscosity for attaching eyelash/hair extension systems to human eyelash/hair, comprising: a cyanoacrylate monomer having a straight alkyl chain length of from 4 to 16 carbon atoms; an organic polymer thickening agent; an inorganic thickening agent; and a bonding accelerator, wherein the inorganic thickening agent does not separate from the composition.

         35 . A method for attaching an eyelash/hair extension to natural eyelash/hair, comprising:
 (a) providing an adhesive composition comprising a mixture of:
 a cyanoacrylate monomer selected from the group consisting of 2-octyl cyanoacrylate monomer, n-butyl cyanoacrylate monomer, and a mixture of 2-octyl cyanoacrylate monomer and n-butyl cyanoacrylate monomer, about 200 to about 15,000 parts per million (ppm) of butylated hydroxyl anisole and about 10 ppm to about 200 ppm of sulfur dioxide, 
 an organic polymer thickening agent comprising a partial polymer of 2-octyl cyanoacrylate, 
 about 0.8% to 7% by weight of untreated fumed silica, 
 about 0.02% to 0.5% by weight of 18-crown-6 crown ether, 
 wherein the composition has a viscosity of from about 100,000 to about 500,000 centipoise (cps); 
   (b) applying the adhesive to the hair/eyelash extension; and   (c) attaching and bonding the extension to the natural hair/eyelash.   
     
     
         36 . The method of  claim 35  wherein the adhesive composition bonds the hair/eyelash extension to the natural hair/eyelash in less than 15 seconds. 
     
     
         37 . The method of  claim 36  wherein the adhesive composition bonds the hair/eyelash extension to the natural hair/eyelash in less than 10 seconds. 
     
     
         38 . The method of  claim 37  wherein the adhesive composition bonds the hair/eyelash extension to the natural hair/eyelash in less than 4 seconds. 
     
     
         39 . An adhesive composition, comprising a mixture of
 a cyanoacrylate monomer selected from the group consisting of 2-octyl cyanoacrylate monomer, n-butyl cyanoacrylate monomer, and a mixture of 2-octyl cyanoacrylate monomer and n-butyl cyanoacrylate monomer, about 200 to about 15,000 parts per million (ppm) of butylated hydroxyl anisole and about 10 ppm to about 200 ppm of sulfur dioxide,   an organic polymer thickening agent comprising a partial polymer of 2-octyl cyanoacrylate,   about 0.8% to 7% by weight of untreated fumed silica,   about 0.02% to 0.5% by weight of 18-crown-6 crown ether,   wherein the composition has a viscosity of from about 100,000 to about 500,000 centipoise (cps) and is packaged in a dispensing applicator container.   
     
     
         40 . The composition of  claim 39  wherein the applicator container is selected from the group consisting of: a vial, a bottle, a pouch, a syringe, and an ampoule.
