Abstract:The present invention relates to composition 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.
Inventor(s): Janssen; Herwig (Princeton, NJ), Ho; Kie (Princeton, NJ), Nystrand; Glenn (Lebanon, NJ), Williams; Dexter (Dayton, NJ), Lamb; C. Scott (Doylestown, PA)
Assignee: Johnson & Johnson Consumer Companies, Inc. (Skillman, NJ)
Application Number:10/230,460
Patent Claims: 1. 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: a solution of an effective amount of one or more agents, having pediculicidal and ovacidal properties, selected from the group consisting of Spinosad, Spinosyn, Spinosyn A, Spinosyn D and mixtures thereof and; one or more stabilizers, wherein the stabilizers comprise polyvinyl methyl ether/maleic anhydride ("PVM/MA") decadiene crosspolymers; and wherein the stabilizers have a particle size of <75.mu..

2. 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: a solution of an effective amount of one or more agents, having pediculicidal and ovacidal properties, selected from the group consisting of Spinosad, Spinosyn, Spinosyn A, Spinosyn D and mixtures thereof and; one or more stabilizers, wherein the stabilizers comprise polyvinyl methyl ether/maleic anhydride ("PVM/MA") decadiene crosspolymers; and wherein the solution comprises a solvent consisting of one or more of the following: benzyl alcohol, pentylene glycol, isopropyl alcohol, hexylene glycol, butylene glycol, and dipropylene glycol.

3. 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: a solution of an effective amount of one or more agents, having pediculicidal and ovacidal properties, selected from the group consisting of Spinosad, Spinosyn, Spinosyn A, Spinosyn D and mixtures thereof; one or more stabilizers, wherein the stabilizers comprise polyvinyl methyl ether/maleic anhydride ("PVM/MA") decadiene crosspolymers; one or more moisturizers; one or more emulsion stabilizers; one or more emulsifying agents; one or more conditioning agents; one or more antioxidants; and one or more pH adjuster.

4. The method of claim 3 wherein the moisturizer comprises propylene glycol.

5. The method of claim 3 wherein the emulsion stabilizer comprises a mixture of cetyl and stearyl alcohols.

6. The method of claim 3 wherein the emulsifying agent comprises Ceteareth-20.

7. The method of claim 3 wherein the conditioning agent comprises stearalkonium chloride.

8. The method of claim 3 wherein the antioxidant comprises butylated hydroxytoluene ("BHT").

9. The method of claim 3 wherein the pH adjuster comprises sodium hydroxide.

10. The method of claim 3 further comprising one or more viscosity increasing agents.

11. The method of claim 10 wherein the viscosity increasing agent comprises a mixture of cetyl and stearyl alcohols.

12. 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: about 44% water; about 1.1% PVM/MA decadiene crosspolymer; About 3% propylene glycol; About 3% cetearyl alcohol; About 0.9% ceteareth-20; About 4.17% stearalkonium chloride; About 10% benzyl alcohol; About 6% hexylene glycol; About 4% pentylene glycol; About 20% isopropyl alcohol; About 2.19% mixture of spinosyn A and spinosyn D in an approximate 85:15 weight ratio; About 0.1% BHT; and 1.29% sodium hydroxide (10% solution).
