CLAIM OF PRIORITY  
       [0001]     This patent application claims the benefit of provisional patent application number 60/751,018, filed Dec. 16, 2005. 
     
    
     FIELD OF INVENTION  
       [0002]     The present invention relates to a new cosmetic remover composition, principally a makeup and “permanent” lip coloring remover.  
       BACKGROUND OF THE INVENTION  
       [0003]     Two types of long-lasting or “permanent” makeup are particularly difficult to remove: “Permanent” lip colors, which are actually paints or shellacs that seal the color under a polymer film, and liquid face makeups, which are generally silicone-in-silicone emulsions. Although both types of products do not smudge or come off easily, requiring less maintenance, both are also quite difficult to remove when the user wants to take them off. Most current cosmetic remover compositions are ineffective at removing such “permanent” cosmetics. A cosmetic remover composition that easily removes either permanent lip colors or permanent face makeups, or both, is highly desirable, particularly if such a composition is gentle to the skin.

     DETAILED DESCRIPTION OF THE INVENTION  
       [0039]     The present invention relates to a cosmetic removal composition that functions in two ways: (1) by dissolving the polymer film for permanent lip colorings, and (2) by resolublizing the silicone based compositions of permanent makeup.  
         [0040]     In a preferred embodiment, there is additionally a deposition of agents, such as essential fatty acids, found in interstitial fluids of the skin and ceramides found in the collagen layer after removal is completed. Silicone crosslinked polymers are known to provide a light, silky feel on skin and hair.  
         [0041]     It is well known that silicones constitute active beneficial ingredients for various cosmetic formulations, its selection and form of incorporation in various cosmetic formulations is important to achieve the desired stability, compatibility with various other ingredients, and importantly, the effective deposition of the silicones onto substrates as beneficial agents. The cosmetic composition can be provided in variety of formulations, in particular, cleansing or health care formulations for cosmetic applications.  
         [0042]     A working example of the composition of the present invention is detailed in Table 1 below. The cosmetic remover composition of the invention may be provided in gel or liquid form, and may be sold in a tube, roll-on dispenser, tub or pump dispenser.  
                                                                   TABLE 1                           Chemical composition of cosmetic remover                    Name: CTFA or       Formula               Chemical   USP (Vendor trade       Qty,       Phase   ID Code   name)   Formula. %   lbs   Function                    A   Cyclomethicane   Cyclopentasiloxane   89.000       Silicon elastomer           (generic)   (and)           moisture barrier           Dow 344,   Dimethicone/Vinyl           and makeup           345   Dimethicone           remover long               Crosspolymer           lasting makeup and                           lipstick is silicon                           based, and is                           dissolved by this                           silicon polymer       B       Dioctyldodecyl   0.500       Essential fatty               Dimer Dilinoleate           acids nutritive to               (and) Omega-6-           the skin, found in               linoleic acid           the interstitial fluid       B       Ceramide 3   0.500       Skin identical                           ceramides found                           also in the collagen                           layer       B       Octyl cocoate   10.00       Silicon compatible                           emollient and skin                           softner                  
 
         [0043]     The composition of phase A is comprised of two compounds: (1) a specialty silicon cross polymer with solvent properties (dimethicone/vinyl dimethicone copolymer) mutually soluble in virtually all of the various combinations of ingredients used in today&#39;s commercial transfer-resistant lip colorings and face and eye cosmetics; and (2) a cyclic dimethyl polysiloxane (here which helps to provide a useable consistency for the cosmetic remover, and also functions as an emollient.  
         [0044]     The present invention removes the lip color by dissolving or solublizing the color containing semi-permanent film adhering to the skin or mucous membranes. This film is primarily composed of synthetic polymers such as polyvinylpyrollicone/hexadecane copolymer, PPG-51 SMDI copolymer, vinyl acetate, acrylic acid esters and a barrier forming silicones such as trimethylsiloxy silicate. The present invention removes permanent makeup based on silicone in silicone emulsion by solublizing the makeup.  
         [0045]     In a preferred embodiment, the present invention provides a polymer and ester combination comprised of a unique silicon crosspolymer with solvent properties combined with a cyclic dimethyl polysiloxane and, optionally, a compatible and soluble emollient oil (such as octyl cocoate), which is an ester derived from coconut oil. The silicone crosspolymer&#39;s uniqueness comes from its ability to codissolve the many film-forming components of the various transfer-resistant commercial products. While many other silicone derivatives can also solublize the various components of the semi permanent films, silicone crosspolymers with dissolving properties have been discovered to work quickly and completely to remove the film. The color containing film is removed instantly when applied to the lip, face or eyelids, eyelashes and then wiped off with a tissue. A single application completely removes the film and the color.  
         [0046]     Currently commercial available lipstick and makeup removers, such as Cover Girl clean makeup remover for eyes and lips (contains mainly mineral oil) and Revlon Color Stay Eye &amp; Lip Makeup Remover, (which itself contains a silicon crosspolymer-dimethicone crosspolymer-3—that does not have solvent properties) do not have sufficient solublizing power to instantly remove the lip coloring or other cosmetic completely with one application.  
         [0047]     The organic oil that is used to add softening effect and emmoliency to the skin is octyl cocoate, or ethylhexyl palmitate, a higher quality version of octyl cocoate (higher distillate). It is preferred to use the octyl cocoate as the emollient, but many other esters can be used and include; hexadecyl laurate, hexyldecyl palmitate, hexydecyl stearate, cetyl palmitate, cetyl laurate, cetyl isononanoate, cetyl strarate, stearyl stearate, etc. Success with the octyl cocoate has been achieved with a single application.  
         [0048]     Also included in the desired formulation of the invention are essential fatty acids (EFA&#39;s) and skin identical ceramides, which are composed of the same material as the interstitial fluid that is located between the cells of the skin and are among the main component of collagen.  
         [0049]     Dimethicone/vinyldimethicone crosspolymer is the preferred silicone crosspolymer with solvent properties, but other silicone crosspolymers with solvent properties may be used, including: cetearyl dimethicone/vinyldimethicone crosspolymer, PEG 12 dimethicone crosspolymer, PEG 10 dimethicone crosspolymer, vinyldimethicone/methicone silsesquioxane crosspolymer (and blends of the above with dimethicone and/or cyclomethicones and the like).  
         [0050]     The silicone crosspolymer is preferably mixed with cyclopentasiloxane to give the composition a smoother texture and reduce its viscosity. In addition to cyclopentasiloxanes, the following silicone based polymers have also been found effective at providing the proper consistency and include cycloheptasiloxane, cyclohexasiloxane, cyclomethicones, cyclotetrisiloxane, cyclotrisiloxane, dimethicone (and combinations of the former with dimethicone) and (combinations of all of the above without dimethicone).
