Abstract

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.

Claims

1. 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; and

(e) 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 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 1, 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 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.

11. The composition according to claim 1, wherein said composition is in the form of a clear or translucent gel.

12. 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.

13. The composition according to claim 1, further comprising one or more colorants.

15. A method for providing prolonged delivery of a fragrance oil comprising applying to a surface a composition according to claim 1.

16. The method according to claim 15, wherein said surface is a human integument.

14. 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 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.

17. 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;

(d) an alcohol; and

(e) an insect repellant oil,

wherein the composition is capable of releasing said insect repellant 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.
