Abstract

The present invention is directed to a composition containing: at least one cross-linked copolymers of acrylic acid and a hydrophobic co-monomer; at least one neutralized polyacrylic acid; at least one silicone acrylate; oil; water; and at least one sunscreen active, wherein the composition is initially clear in appearance and remains clear in appearance upon application onto wet skin.

Claims

1. A composition consisting of:

(a) an acrylates/C10-30 alkyl acrylate crosspolymer;

(b) a neutralized polyacrylic acid selected from the group consisting of sodium, potassium, lithium and ammonium neutralized salts of polyacrylic acid;

(c) a silicone acrylate selected from the group consisting of an acrylates/dimethicone copolymer and a graft copolymer having an acrylic acid polymer backbone and polydimethylsiloxane side chains;

(d) an oil;

(e) a sunscreen active;

(f) an emulsifier;

(g) one or more of a chelating agent, a preservative, a propellant, an anti-oxidant, silica, pH adjuster, and a monohydric C1-C8 alcohol; and

(h) water,

wherein the composition is initially clear in appearance and remains clear in appearance and does not result in one or more of a white appearance and white streaking upon application onto a wet keratinous substrate.

2. The composition of claim 1 wherein (a) is present in an amount of about 0.01 to 0.5% by weight, based on the total weight of the composition.

3. The composition of claim 1 wherein (a) is present in an amount of about 0.01 to 0.4% by weight, based on the total weight of the composition.

4. The composition of claim 1 wherein (b) is sodium polyacrylate.

5. The composition of claim 4 wherein (b) is present in an amount of about 0.01 to 0.5% by weight, based on the total weight of the composition.

6. The composition of claim 4 wherein (b) is present in an amount of about 0.01 to 1% by weight, based on the total weight of the composition.

7. The composition of claim 1 wherein (c) is an acrylates/dimethicone copolymer.

8. The composition of claim 7 wherein (c) is present in an amount of about 0.01 to 20% by weight, based on the total weight of the composition.

9. The composition of claim 7 wherein (c) is present in an amount of about 0.01 to 10% by weight, based on the total weight of the composition.

10. The composition of claim 1 wherein (d) is present in an amount of about 0.1 to 40% by weight, based on the total weight of the composition.

11. The composition of claim 1 wherein (d) is present in an amount of about 0.1 to 30% by weight, based on the total weight of the composition.

12. The composition of claim 1 wherein (e) is present in an amount of about 0.1 to 40% by weight, based on the total weight of the composition.

13. The composition of claim 1 wherein

(a) the acrylates/C10-30 alkyl acrylate crosspolymer is present in an amount of about 0.01 to 0.5% by weight, based on the total weight of the composition, and

(b) is sodium polyacrylate present in an amount of about 0.01 to 0.5% by weight, based on the total weight of the composition, and

(c) is an acrylates/dimethicone copolymer present in an amount of about 0.01 to 20% by weight, based on the total weight of the composition, and

(d) is present in an amount of about 0.1 to 40% by weight, based on the total weight of the composition, and

(e) is present in an amount of about 0.1 to 40% by weight, based on the total weight of the composition.

15. A method of protecting a keratinous substrate from UV rays comprising applying onto the keratinous substrate the clear composition according to claim 1.

14. A composition consisting of:

(a) from about 0.01 to about 0.3% by weight of acrylates/C10-30 alkyl acrylate crosspolymer;

(b) from about 0.01 to about 0.75% by weight of sodium polyacrylate;

(c) from about 0.05 to about 5% by weight of acrylates/dimethicone copolymer;

(d) from about 0.1 to about 30% by weight of oil;

(e) from about 0.1 to about 40% by weight of sunscreen active;

(f) an emulsifier;

(g) one or more of a chelating agent, a preservative, a propellant, an anti-oxidant, silica, pH adjuster, and a monohvdric C1-C8 alcohol; and

(h) water,

wherein the composition is initially clear in appearance and remains clear in appearance and does not result in one or more of a white appearance and white streaking upon application onto a wet keratinous substrate.
