Abstract

Cationically-charged particulates and compositions containing the cationically-charged particulates for application to keratinous materials are provided. Methods of preparing the cationically-charged particulates are also disclosed.

Claims

1. A composition for application to keratinous surfaces, the composition comprising particulates encapsulated in a first, inner coating comprising a first material, and in a second, outer coating comprising a second material, in a cosmetically acceptable carrier, the first coating comprising a cationically-charged material in an amount sufficient to impart a cationic charge in the range of from about 0.1 mV to about 400 mV to the particulates, and the second coating comprising a film former material in an amount sufficient to render the particulates hydrophobic, wherein a weight ratio of the cationically-charged material to the particulates is in the range of from about 0.1:

1 to about 5;

1.

2. The composition of claim 1, wherein the encapsulated particulates have a cationic charge in the range of from about 60 mV to about 150 mV.

3. The composition of claim 1, wherein the cationically charged material comprises a naturally-derived or a synthetic cationic polymer.

4. The composition of claim 3, wherein the naturally-derived cationic polymer comprises a cationically charge-modified derivative of at least one of guar gum, cellulose, a protein, a polypeptide, chitosan, lanolin, or a starch.

5. The composition of claim 3, wherein the synthetic cationic polymer comprises polyquaternium-4, polyquaternium-5, polyquatemium-6, polyquaternium-10, polyquatemium-39, polyquaternium-44, polyquaternium-46, distearyldimonium chloride, cinnamidopropyltrimonium chloride, cetrimonium chloride, and guar hydroxypropyltrimonium chloride, or a combination of any two or more thereof.

6. The composition of claim 5, wherein the synthetic cationic polymer comprises polyquaternium-6.

7. The composition of claim 1, wherein the cationically-charged material comprises iron oxide.

8. The composition of claim 1, wherein the film former material comprises a silicone, an acrylates polymer, an acrylates copolymer, a polyvinylpyrrolidone (PVP) derivative, a polyurethane, a polyvinyl amine, a polyvinyl acetate, sucrose acetate isobutyrate, or a combination of any two or more thereof.

9. The composition of claim 8, wherein the film former material comprises dimethicone and trimethylsiloxy silicate;

dimethicone, trimethylsiloxysilicate and polyglyceryl-3 disiloxane dimethicone;

or polyurethane.

10. The composition of claim 1, wherein the encapsulated particulates are provided with at least one additional coating beneath the second coating, the additional coating comprising a cationic material, an anionic material, or both, the encapsulated particulates retaining the cationic charge in the range of from about 0.1 mV to about 400 mV.

11. The composition of claim 10, wherein the cationic material is a grape seed extract.

12. The composition of claim 1, wherein the particulates are in the form of naturally-derived powder particulates, fibers, or a combination thereof.

13. The composition of claim 12, wherein the particulates are derived from hcellulose;

a cellulose-based material;

polylactic acid, or a combination of any two or more thereof.

14. The composition of claim 13, wherein the cellulose-based material comprises cellulose (and) magnesium stearate, cotton, linen, rayon, or a combination of any two or more thereof.

15. The composition of claim 12, wherein the particulates are in the form of fibers having a length in the range of from about 1 micrometer to about 4 millimeters and a weight in the range of from about 3 to about 20 denier.

16. The composition of claim 15, wherein the fibers have a length in the range of from about 1 to 2 millimeters and a weight in the range of from about 5 to about 10 denier.

17. The composition of claim 15, wherein the fibers have a cross-sectional shape which is round, oval, triangular, hexagonal, heart-shaped, star-shaped, or a combination of any two or more thereof.

18. The composition of claim 1, wherein the encapsulated particulates are present in the composition in the range of from about 0.1 to about 4 percent by total weight of the composition.

19. The composition of claim 1, which is in the form of an aqueous-containing solution, a dispersion or an emulsion.

20. The composition of claim 1, which is in the form of a mascara, a brow filler or a hair filler.

21. The composition of claim 1, wherein a weight ratio of the film former material to the particulates encapsulated in the first coating is in the range of from about 0.1:

1 to about 60;

1.

22. A treated particulate encapsulated in a first, inner coating comprising a cationically-charged material, and in a second, outer coating comprising a hydrophobic film former material, wherein the cationically-charged material is present in an amount sufficient to impart a cationic charge in the range of from about 0.1 mV to about 400 mV to the treated particulate, and wherein a weight ratio of the cationically-charged material to the particulates is in the range of from about 0.1:

1 to about 5;
