Title: Glue-free Adhesive Eyeleashes

Description:
CROSS REFERENCE TO RELATED APPLICATIONS 
     This application is a non-provisional application which claims priority from U.S. Ser. No. 62/951,238, filed Dec. 20, 2019, the disclosure of which is specifically incorporated by reference herein in its entirety. 
    
    
     FIELD OF THE INVENTION 
     The present invention is in the field of eyelash enhancements. 
     BACKGROUND OF THE INVENTION 
     It is known that eyelash extensions can use magnets to attach upper and under eyelashes to a natural eyelash. It is also known that magnetic eyeliner can be used to attach an eyelash extension to a natural eyelash. Finally, it is also known that adhesive components (glue) can be used to attach an eyelash extension to a natural eyelash. 
     The present invention seeks to improve upon the existing art by offering a new and better alternative way to attach eyelash extensions to natural eyelashes. 
     SUMMARY OF THE INVENTION 
     The present invention is generally directed to a glue-free adhesive for eyelashes and a method for securing eyelashes with a glue-free adhesive. More particularly, the present invention uses effective amounts of arabic gum, casein and polyvinylprrolidone in water to formulate a glue-free adhesive which allows eyelash attachments to be removably attached to eyelashes without the need for use of an adhesive remover to remove the eyelash attachments. 
     Accordingly, it is an object of the present invention to provide an improved eye-lash enhancement which uses a glue-free adhesive. 
     This and further objects and advantages will be apparent to those skilled in the art in connection with the drawings and the detailed description of the invention set forth below. 
    
    
     DETAILED DESCRIPTION OF THE INVENTION 
     In accordance with the present invention, a glue-free composition is used to attach one or more eyelash strip lashes to a natural eyelash. In the context of the present invention, “glue-free” means that the composition exhibits sticky adhesion properties which allow an eyelash strip lash to be removably attachable to a natural eyelash such that such extension can be readily removed without the need for using an adhesive remover composition to effectuate such removal. 
     The glue-free composition of the present invention can be used to attach an upper strip lash, or an under strip lash, or both, to a natural eyelash. To effectuate such attachment, the glue-free composition can be applied to the attachment(s) or to the natural eyelash, or to both, and then the attachment(s) is pressed against the natural eyelash. Because the glue-free composition exhibits sticky adhesive properties, it allows the attachment to remain attached (or stuck) once the attachment has been applied; however, because the glue-free composition does not cause the attachment to bind together tightly with the natural eyelash, the attachment can be removed, without the need for use of an adhesive or glue remover composition, by simply pulling the attachment away from the eye lash in much the same manner as a Post-It® note can be applied to a surface and yet readily removed from the surface. 
     Without intending to limit the present invention to the exact composition of the following formula, it has been found that an especially preferred composition according to the present invention is comprised of between approximately 23-28 weight percent arabic gum (CAS No. 9000-01-5), between approximately 5-8.5 weight percent casein (CAS No. 9000-71-9), between approximately 6-8 weight percent polyvinylpyrrolidone (CAS No. 9003-39-8) and between approximately 58-67 weight percent water (CAS No. 7732-18-5), with one preferred embodiment having a formulation of 25.0 weight percent arabic gum, 7.5 weight percent casein, 7.5 weight percent polyvinylpyrrolidone and 60 weight percent water. It is believed that the weight percentages of the foregoing ingredients may be varied, while additional inert ingredients may be added, and equivalents to such ingredients may be substituted (in appropriate weight percentages), to get substantially the same result, as would be apparent to one skilled in the art exercising routine experimentation after studying the disclosure of the present invention. 
     Accordingly, it will be readily apparent to those skilled in the art that still further changes and modifications in the actual concepts described herein can readily be made without departing from the spirit and scope of the disclosed inventions.
