Abstract

The present invention relates to compositions and methods for administering compositions in solutions for killing adult lice and the ova comprising water, PVM/MA Decadiene crosspolymers, propylene glycol, a mixture of cetyl and stearyl alcohols, Ceteareth-20; stearalkonium chloride; benzyl alcohol; hexylene glycol; pentylene glycol, isopropyl alcohol; a mixture of spinosyn A and spinosyn D in a weight ratio of 80:20, BHT; and sodium hydroxide.

1 - 26 . (canceled)  
   
   
       27 . A method of controlling adults and ova of the species of order Anoplura by topically applying to one or more of skin and hair a composition comprising: 
 an effective amount of one or more agents having pediculicidal and ovacidal properties in solution;    one or more stabilizers, wherein the stabilizer comprises polyvinyl methyl ether/maleic anhydride (“PVM/MA”) decadiene crosspolymers; and 
 wherein the agents comprise a chemical structure of:  
                     
   
   
   
       28 . (canceled)  
   
   
       29 . The method of  claim 27 , wherein the agents consist of one or more of the following: spinosad, spinosyn, spinosyn A, spinosyn D, any component produced by the  Saccharopolyspora spinosa  species and a combination thereof.  
   
   
       30 . The method of  claim 27 , wherein R comprises H.  
   
   
       31 . The method of  claim 27 , wherein R comprises CH 3 .  
   
   
       32 . The method of  claim 27 , wherein R comprises a mixture of H:CH 3 .  
   
   
       33 . The method of  claim 27 , wherein R comprises a mixture of H:CH 3  wherein the relative structures are in a weight ratio of approximately 85:15.  
   
   
       34 . The method of  claim 27 , wherein the agents comprise greater than about 0 to about 10 percent of the composition.  
   
   
       35 . The method of  claim 27  wherein the agents comprise between about 0.5 to about 5 percent of the composition.  
   
   
       36 . (canceled)  
   
   
       37 . (canceled)  
   
   
       38 . The method of  claim 27  wherein the stabilizers comprises about 0.5 to about 1.5 percent of the composition.  
   
   
       39 - 74 . (canceled)  
   
   
       75 . The method of  claim 27  wherein the composition comprises about 46% solvents.  
   
   
       76 . The method of  claim 27  wherein the composition comprises at least about 46% solvents.
