Extended release fragrance compositions
View Patent ↗Compositions are provided that provide release of fragrance over an extended period of time. The compositions comprise a hydrophilically-modified cross-linked silicone elastomer and an acrylic rheology modifier.
1. A long-wearing composition for providing extended release of fragrance, said composition comprising:
(a) from about 0.5% to about 5% by weight of a hydrophilically-modified cross-linked silicone elastomer;
(b) from about 0.5% to about 5% 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 2% to about 10% by weight of a fragrance oil,
wherein the composition is capable of releasing said fragrance oil over a longer period of time as compared to an otherwise identical composition lacking either said hydrophilically-modified cross-linked silicone elastomer or said acrylic rheology modifier.
2. The composition according to claim 1 , wherein said hydrophilically-modified cross-linked silicone elastomer comprises poly(alkylene oxide) chains grafted to a silicone backbone.
3. The composition according to claim 1 , wherein said hydrophilically-modified cross-linked silicone elastomer comprises PEG-12 dimethicone/PPG-20 crosspolymer.
4. The composition according to claim 1 , wherein said acrylic rheology modifier comprises a copolymer of an acrylate monomer and an acrylamide monomer.
5. The composition according to claim 1 , wherein said acrylic rheology modifier comprises hydroxylethyl acrylate/sodium acryloyldimethyltaurate copolymer.
6. The composition according to claim 1 , wherein said polyol comprises glycerin and said alcohol comprises ethanol.
7. The composition according to claim 1 , wherein said fragrance oil comprises a blend of one or more fragrance oils.
8. The composition according to claim 1 , 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.
9. The composition according to claim 1 , 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.
10. The composition according to claim 1 , further comprising one or more colorants.
11. The method according to claim 1 , wherein said surface is a human integument.
12. The composition according to claim 1 , wherein the weight ratio of said polyol to said alcohol from about 2:1 to about 1:2.
