Assignee:
Application Number:	14/547,439
Patent Claims:	1. An insect repellant composition that provides extended release of an insect repellant oil, comprising: (a) a hydrophilically-modified cross-linked silicone elastomer; (b) an acrylic rheology modifier; (c) a polyol, said polyol comprising glyercin; (d) an alcohol, said alcohol comprising ethanol; and (e) an insect repellant oil, wherein said alcohol comprises from about 20% to about 75% of the composition, wherein said composition is substantially anhydrous. 2. A composition for providing extended release of fragrance comprising: (a) a hydrophilically-modified cross-linked silicone elastomer; (b) an acrylic rheology modifier; (c) a polyol; (d) an alcohol comprising ethanol; and (e) a fragrance oil, wherein said alcohol comprises from about 20% to about 75% of the composition, wherein said composition is substantially anhydrous. 3. The composition according to claim 2, wherein said hydrophilically-modified cross-linked silicone elastomer comprises poly(alkylene oxide) chains grafted to a silicone backbone. 4. The composition according to claim 2, wherein said hydrophilically-modified cross-linked silicone elastomer comprises PEG-12 dimethicone/PPG-20 crosspolymer. 5. The composition according to claim 2, wherein said acrylic rheology modifier comprises a copolymer of an acrylate monomer and an acrylamide monomer. 6. The composition according to claim 2, wherein said acrylic rheology modifier comprises hydroxylethyl acrylate/sodium acryloyldimethyltaurate copolymer. 7. The composition according to claim 2, wherein said fragrance oil comprises a blend of one or more fragrance oils. 8. The composition according to claim 2, wherein said hydrophilically-modified cross-linked silicone elastomer is present in an amount from about 0.5% to about 5% by weight of the total composition. 9. The composition according to claim 2, wherein said acrylic rheology modifier is present in an amount from about 0.5% to about 5% by weight of the total composition. 10. The composition according to claim 2, wherein the weight ratio of said hydrophilically-modified cross-linked silicone elastomer and said acrylic rheology modifier is from about 2:1 to about 1:2. 11. The composition according to claim 2, further comprising one or more actives selected from the group consisting of: retinoids, hydroxyl acids, depigmenting agents, botanicals, collagenase inhibitors, elastase inhibitors, sunscreens, anti-perspirants, deodorants, anti-bacterias, and anti-fungals. 12. The composition according to claim 2, further comprising one or more colorants. 13. A method for providing prolonged delivery of a fragrance oil comprising applying to a surface a composition according to claim 2. 14. The method according to claim 13, wherein said surface is a human integument. 15. The composition according to claim 2, wherein said alcohol comprises from about 25% to about 65% by weight of the composition. 16. A long-wearing composition for providing extended release of fragrance, said composition comprising: (a) from about 0.5% to about 10% by weight of a hydrophilically-modified cross-linked silicone elastomer; (b) from about 0.1% to about 25% by weight of an acrylic rheology modifier; (c) from about 20% to about 75% by weight of a polyol; (d) from about 20% to about 75% by weight of an alcohol; and (e) from about 0.5% to about 25% by weight of a fragrance oil, wherein said alcohol comprises ethanol, wherein said composition is substantially anhydrous. 17. The composition according to claim 16, wherein said alcohol comprises from about 25% to about 65% by weight of the composition.
