Extended release insect repellant or fragrance compositions
View Patent ↗Compositions are provided that provide release of insect repellant or fragrance over an extended period of time. The compositions comprise a hydrophilically-modified cross-linked silicone elastomer and an acrylic rheology modifier.
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.
