1 . A method for treating a fabric article in need of treatment comprising contacting the fabric article with a glycerine derivative solvent.  
   
   
       2 . The method according to  claim 1  wherein the glycerine derivative solvent has the following structure:  
     
       
         
         
             
             
         
       
     
     wherein R 1 , R 2  and R 3  are each independently selected from: H; branched or linear, substituted or unsubstituted C 1 -C 30  alkyl, C 2 -C 30  alkenyl, C 1 -C 30  alkoxycarbonyl, C 3 -C 30  alkyleneoxyalkyl, C 1 -C 30  acyloxy, C 7 -C 30  alkylenearyl; C 4 -C 30  cycloalkyl; C 6 -C 30  aryl; and mixtures thereof; wherein two or more of R 1 , R 2  and R 3  together can form a C 3 -C 8  aromatic or non-aromatic, heterocyclic or non-heterocyclic ring.  
   
   
       3 . The method according to  claim 1  wherein the glycerine derivative solvent is selected from the group consisting of: 1,3-di-tertiary-butoxy glycerol; 1,2-di-t-butoxy glycerol; 1-t-butoxy glycerol; 2-t-butoxy glycerol; 1,3-di-n-butoxy glycerol; 1,2-di-n-butoxy glycerol; 1-n-butoxy glycerol; 2-n-butoxy glycerol; 2,3-bis(1,1-dimethylethoxy)-1-propanol; 2,3-dimethoxy-1-propanol; 3-methoxy-2-cyclopentoxy-1-propanol; 3-methoxy-1-cyclopentoxy-2-propanol; carbonic acid (2-hydroxy-1-methoxymethyl)ethyl ester methyl ester; glycerol carbonate and mixtures thereof.  
   
   
       4 . The method according to  claim 1  wherein the glycerine derivative is produced by reacting an epichlorohydrin with an alcohol.  
   
   
       5 . The method according to  claim 1  wherein the method further comprises the step of contacting the fabric article with an adjunct solvent.  
   
   
       6 . The method according to  claim 5  wherein the adjunct solvent comprises a lipophilic fluid.  
   
   
       7 . The method according to  claim 6  wherein the lipophilic fluid comprises a linear siloxane, a cyclic siloxane and mixtures thereof.  
   
   
       8 . The method according to  claim 6  wherein said lipophilic fluid comprises a lipophilic fluid selected from the group consisting of octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, dodecamethylcyclohexasiloxane, and mixtures thereof.  
   
   
       9 . The method according to  claim 6  wherein said lipophilic fluid comprises decamethylcyclopentasiloxane.  
   
   
       10 . The method according to  claim 1  wherein the method occurs at less than about 80° C.  
   
   
       11 . The method according to  claim 1  wherein the method further comprises the step of contacting the fabric article with a polar phase.  
   
   
       12 . The method according to  claim 11  wherein said polar phase comprises water or C1-C16 alcohols.  
   
   
       13 . The method according to  claim 11  wherein said polar phase comprises at least about 0.1% water by weight of the fabric article.  
   
   
       14 . The method according to  claim 11  wherein said polar phase comprises at most about 10% water by weight of the fabric article.  
   
   
       15 . The method according to  claim 1  wherein the method further comprises contacting said fabric article with an adjunct ingredient.  
   
   
       16 . The method according to  claim 15  wherein the adjunct ingredient comprises a surfactant.  
   
   
       17 . A fabric article treated by the method of  claim 1.
