Abstract

Cosmetic article ( 1 ) for application to the eyelid, the eyelashes and/or the eyebrows, including:—at least one element ( 2 ) to be applied,—at least one adhesive layer ( 5 ) which is at least partially in contact with the element ( 2 ) to be applied, this adhesive layer ( 5 ) including at least one water-resistant adhesive material, and—at least one layer ( 6 ) for protecting the adhesive layer ( 5 ), externally covering same and including at least one water-soluble polymer.

Claims

exact text as granted — not AI-modified
1 . Cosmetic article ( 1 ) for application to the eyelid, the eyelashes and/or the eyebrows, including:
 at least one element ( 2 ) to be applied,   at least one adhesive layer ( 5 ) which is at least partially in contact with the element ( 2 ) to be applied, this adhesive layer ( 5 ) including at least one water-resistant adhesive material, and   at least one layer ( 6 ) for protecting the adhesive layer ( 5 ), externally covering same and including at least one water-soluble polymer.   
     
     
         2 . Article ( 1 ) according to  claim 1 , in which the element ( 2 ) to be applied includes a false eyelash ( 3 ) or a tuft of false eyelashes ( 3 ), the adhesive layer ( 5 ) coated with the protective layer ( 6 ) being located at one end of the false eyelash ( 3 ) or of the tuft of false eyelashes ( 3 ). 
     
     
         3 . Article ( 1 ) according to  claim 1 , in which the element ( 2 ) to be applied includes a false eyelash fringe ( 3 ) and a connecting strip ( 25 ), the false eyelashes ( 3 ) being fixed, via one end, to the connecting strip ( 25 ), said connecting strip ( 25 ) being at least partially covered with the adhesive layer ( 5 ). 
     
     
         4 . Article ( 1 ) according to  claim 1 , in which the element ( 2 ) to be applied includes a shell, a patch or a strip for the eyelid. 
     
     
         5 . Article ( 1 ) according  claim 1 , in which the water-resistant adhesive material is a water-resistant pressure-sensitive adhesive (PSA) selected from the group consisting of acrylic polymers, notably copolymers of acrylate and methacrylate, pressure-sensitive adhesives based on rubber or based on styrene copolymers. 
     
     
         6 . Article ( 1 ) according to  claim 1 , in which the protective layer ( 6 ) includes a hydrophilic polymer, in dry form. 
     
     
         7 . Article ( 1 ) according to  claim 6 , in which the hydrophilic polymer is chosen such that its glass transition temperature T g  is greater than or equal to 30° C. 
     
     
         8 . Article ( 1 ) according to  claim 1 , in which said at least one polymer of the protective layer ( 6 ) may be selected from the group consisting of polyvinylpyrrolidones (PVP), polyvidones, povidones, polysaccharides, and polyvinyl alcohols (PVA). 
     
     
         9 . Article ( 1 ) according to  claim 1 , in which the protective layer ( 6 ) entirely covers the adhesive layer ( 5 ) before use of the article, uniformly. 
     
     
         10 . Packaging assembly including at least one cosmetic article ( 1 ), according to  claim 1 , and a packaging for containing same. 
     
     
         11 . Process for manufacturing a cosmetic article ( 1 ) according to  claim 1  from an element ( 2 ) to be applied, including the following steps:
 depositing the adhesive layer ( 5 ) onto at least a part of the element ( 2 ) to be applied, 
 where appropriate, drying the adhesive layer ( 5 ), 
 at least partially, covering this adhesive layer ( 5 ) with the protective layer ( 6 ), in a fluid state, 
 where appropriate, drying the protective layer ( 6 ). 
 
     
     
         12 . Process for applying to the eyelid, the eyelashes and/or the eyebrows a cosmetic article ( 1 ) according to  claim 1 , including the following steps:
 (a) placing at least the protective layer ( 6 ) of the cosmetic article ( 1 ) in contact with water, until said protective layer ( 6 ) has at least partially dissolved,   (b) applying the article to the eyelid, the eyelashes and/or the eyebrows by placing the adhesive layer ( 5 ) in contact with the eyelid, the eyelashes and/or the eyebrows.   
     
     
         13 . Article ( 1 ) according to  claim 6 , in which the hydrophilic polymer is chosen such that its glass transition temperature T g  is greater than or equal to 60° C. 
     
     
         14 . Article ( 1 ) according to  claim 6 , in which the hydrophilic polymer is chosen such that its glass transition temperature T g  is greater than or equal to 80° C. 
     
     
         15 . Process according to  claim 11 , wherein the adhesive layer ( 5 ) is totally covered with the protective layer ( 6 ).
