     FIELD OF THE INVENTION 
     The present invention relates to a series of crosslinked silicone polymers that by virtue of the nature of the crosslinker, have unique solubility and properties. These include improved tolerance for oily materials and water soluble materials. These polymers find use in personal care applications like pigmented products. In the personal care arena, solid products that do not experience syneresis are important. Syneresis is a condition that exists in a solid product that causes a liquid that is incompatible to ooze out, which is cosmetically unacceptable. 
     BACKGROUND OF THE INVENTION 
     The term silicone resin has been applied both to and misapplied to a variety of materials over time. Silicone resins as used herein refer to a series of products which include at least two silicone backbones that are joined by a “crosslinking group”. The number of crosslinking groups that are present as a percentage of the total molecular weight will determine the properties of the resulting polymer. 
     If there are no crosslinking groups; the polymer can freely rotate and consequently is an oily liquid. If a few crosslinking groups are introduced, the ability to rotate is slightly restricted and the oily material becomes “rubbery”. The rubbery material should be referred to as an elastomer. The properties are morel like a rubber band than plastic. As the percentage of crosslinking increases still the molecule becomes rigid. This class of compounds are resins. If you hit the film with a hammer and it shatters it is a resin, if it bounces it is an elastomer and if it squirts out is a silicone fluid. 
     The difficulty in determining if a product is a fluid an elastomer or resin occurs for products that lie between the classifications. Specifically, when does an elastomer become a resin? While this exact point is of academic interest it does not have nay practical significance to the present invention. 
     There are a number of classes of resin compounds differing in the nature of the crosslinker. One class is the so called “Q resins”. 
     
       
                 
         
             
             
         
      
     
     The oxygen that needs another bond connects to another polymer as shown: 
     
       
                 
         
             
             
         
      
     
     The crosslinking group is —O—. This type of resin is disclosed in U.S. Pat. No. 6,139,823, incorporated herein by reference. This type of material has a group, the so called “Q” group in which a Si has four oxygen atoms attached. In the above case it is the group that is within the “a” subscript. This type of resin is very powdery and is rarely used without a plasticizer. This class of compounds can also dry the skin. 
     The next class of resin contain alkyl connecting groups. 
     
       
                 
         
             
             
         
      
     
     In the case where n=1 acetylene is used as a crosslinking reactant. It is reacted with a silanic hydrogen polymer. As n is increased the reactant is an alpha omega divinyl compound. 
     
       
                 
         
             
             
         
      
     
     The reaction is called hydrosilylation and provides the linking groups between the molecules. The reaction is generally run in solvent like cyclomethicone (D4 or D5 or hexamethyl disiloxane) or in volatile organic like isododecane. A catalyst generally a platinum one is used to effect the reaction. Chloroplatinic acid or Karnsteadt catalyst are preferred. The resulting material is a viscous liquid that when the solvent evaporates provides a film. 
     The present invention makes use of novel crosslinking reagents that provide groups that significantly alter the solubility of the resin. This is done by introducing fatty ester linkages, water soluble groups linked with fatty esters and glyceryl esters. Not only does the solubility change, the ability to formulate solid products free from syneresis also occurs. Another unexpected benefit is that the ester moiety provides improved biodegradation of the resin making the resin “more green” and improving consumer acceptability. None of these advantageous are present in the compounds known heretofore. 
     THE INVENTION 
     Object of the Invention 
     It is the object of the present invention to provide a series of silicone polymers that have differing crosslinking groups. The groups are all reactive with silanic hydrogen to provide a crosslinked product. The crosslinkers all have ester groups and either a large fatty group or a water soluble group. 
     Another object of the present invention is to provide a series of products suitable for formulation into personal care products providing improved skin feel (i.e. not drying like Q resins) and having improved solubility over alkyl linked polymers. 
     Other objects of the invention will become clear as one reads the specification attached hereto. 
     All % given herein are % by weight, all temperatures are ° C., all patents and publications referred to herein are incorporated herein by reference in their entirety as appropriate. 
     SUMMARY OF THE INVENTION 
     The present invention relates to a series of silicone resins that (a) provide improved water or oil solubility depending upon the specific crosslinker chosen; (b) provide a polar ester linkage in the molecules, which in addition to being more polar than alkylene groups, is also more biodegradable; (c) provide products with a low degree of syneresis when placed in lipstick systems. 
     The compounds of the present invention are made by reacting specific alpha omega multi-vinyl compounds with silicone compounds that contain multiple silanic hydrogen (Si—H) groups. The reaction is conducted in a suitable solvent selected from the group consisting of cyclomethicone (D-4 and D-5 and mixtures thereof) and isoalkanes (isododecane). 
    
    
     DETAILED DESCRIPTION OF THE INVENTION 
     Resins of the present invention are a class of silicone compounds which are prepared by the reaction of a poly-vinyl compound reacted with a silanic hydrogen containing compound. 
                                
wherein;
 
x is an integer ranging from 0 to 2000;
 
y is an integer ranging from 2 to 200;
 
z is an integer ranging from 0 to 200;
 
R is selected from the group consisting of H, —(CH 2 ) e —CH 3 ;
 —(CH 2 ) 3 —O—(CH 2 CH 2 O) f (CH 2 CH(CH 3 )O) g (CH 2 CH 2 O) h —H; 
e is an integer ranging from 6 to 35;
 
f is an integer ranging from 0 to 20;
 
g is an integer ranging from 0 to 20;
 
h is an integer ranging from 0 to 20.
 
     The reactions are typically carried out in a solvent, either volatile silicone (cyclomethicone (D4 or D5 or mixtures thereof) or hydrocarbon solvent like isododecane. A suitable hydrosilylation catalyst like chloroplatinic acid or Karnstedt catalyst are used. 
     The value of “y” determines the degree of crosslinking and consequently if the product is resinous or elastomeric. Elastomeric materials are compounds that are crosslinked to a lesser extent than resins. They are “rubbery” producing films that are rubber band like. Resins in contrast are not rubbery, but ate hard and because of their higher crosslink density form powders when struck by a hammer. 
     We have also found that reaction of methyl undecylenate to make the intermediate esters of the present invention provides a finished product that is free of acid value, as opposed to using the fatty acid. Acid value present in the vinyl intermediates causes problems with hydrosilylation. 
     Crosslinkers 
     We have surprisingly and unexpectently found that by using an organic crosslinker of varying lengths the solubility and film forming properties of the resin can be altered allowing for the preparation of customized films.

     Crosslinker Preparation 
     General Procedure 
     The crosslinkers are made by the transesterification reaction of methyl undecylenate and a variety of hydroxy containing compounds. The reason the methyl ester is used, rather than the acid, is the fact that there is no residual acid value after the reaction is compete. This gives faster and cleaner hydrosilylation reactions. 
     To the specified number of grams of undecylenate is added the specified number of grams of the specified hydroxy containing compound. A catalyst is recommended, although the reaction can be run without one. Preferred catalyst is stannous oxylate. The reaction mixture is heated to 150-200° C. Methanol will distill off as reaction proceeds. The amount of methanol distilled off is measured and used to monitor the reaction. The reaction is also monitored by gas chromatography and saponification value.

     Hydrosilylation 
     Hydrosilylation is a process that reacts terminal vinyl compounds with silanic hydrogen to obtain a Si—C bond. References to this reaction, incorporated herein by reference, include: 
     U.S. Pat. Nos. 3,715,334 and 3,775,452 to Karstedt, shows the use of Pt(O) complex with vinylsilicon siloxane ligands as an active hydrosilylation catalyst. 
     Additional platinum complexes, such as complexes with platinum halides are shown by, U.S. Pat. No. 3,159,601 Ashby and, U.S. Pat. No. 3,220,972, to Lamoreaux. 
     Another hydrosilylation catalyst is shown by Fish, U.S. Pat. No. 3,576,027. Fish prepares a platinum(IV) catalyst by reacting crystalline platinum(IV) chloroplatinic acid and organic silane or siloxane to form a stable reactive platinum hydrosilylation catalyst. 
     General Procedure 
     To the specified number of grams of the specified solvent is added the specified number of grams of the specified silanic hydrogen compound. The mass is mixed well. To that mixture is added the specified number of grams of the specified vinyl compound. The reaction mass is mixed well until homogeneous. To that mixture is added 0.1% Karstedt catalyst, which is commercially available from Geleste. The agitation is stopped and the reaction begins. The reaction mass will thicken over 4 hours. Once the maximum viscosity is reached the reaction is considered complete. The solvent may be distilled off or the product may be sold as prepared without additional purification.

     The nature of the crosslinking group has a profound effect upon functionality of the resin. In this case the group is:
 
—(CH 2 ) 8 —C(O)—O-(EO) a (PO) b (EO) c —C(O)—(CH 2 ) 8 —
 
     The key to understanding the functionality of the resin of the present invention is an appreciation that silicone, oil and water are three mutually immiscible groups. This lack of solubility is the cause of the syneresis (or separation) seen in pigmented products that contain oil, silicone and water. If the molecule has all three groups properly connected the molecule will orientate itself into the lowest free energy. In this configuration the polar, non-polar and silicone portions of the resin and of the formulation will all associate in a matrix. The parts of this linking group that connect to the silicone group are oil soluble. The length of that group is fairly long and symmetrical. The internal group is water loving (polar). Resins with this configuration allows for the incorporation of both oil loving (non-polar non-silicone) and water loving (polar) into a matrix. This produces an emollient property to the skin in a film forming matrix. Both water and oil can be easily accommodated in the formulation. The presence of the ester group helps biodegradability.

     The nature of the crosslinking group has a profound effect upon functionality of the resin. In this case the group is: 
                                
In this configuration, type of group present in the crosslinker is quite large and branched. It contains an appreciable polar group, including a free ester group. The resin will orientate itself differently in the presence of silicone, polar and non-polar groups. This type of resin has a low viscosity due to the branching and has a great deal of elastic properties. That is an ability to solubilize oil minimizes syneresis and solubilize the oily esters present in lipsticks. The presence of the ester group also improves biodegradation.
 
     As is clear the ability to change the linking group within a resin results in a variety of changes in the ability to make personal care products that have desirable properties. This relates to the ability to keep oil soluble materials, water soluble materials and silicone soluble materials in the same formulation, providing a cosmetically acceptable product. The products of the present invention allow for greater formulation latitude and also allow for the introduction of new products hereto for not attainable. 
     While the illustrative embodiments of the invention have been described with particularity, it will be understood that various other modifications will be apparent to and can be readily made by those skilled in the art without departing from the spirit and scope of the invention. Accordingly, it is not intended that the scope of the claims appended hereto be limited to the examples and descriptions set forth hereinabove but rather that the claims be construed as encompassing all the features of patentable novelty which reside in the present invention, including all features which would be treated as equivalents thereof by those skilled in the art to which the invention pertains.
