1. A rinse-off skin care composition, comprising: hydrophobic, linear cellulose particles derived from cotton, having an average length of less than about 1000 tJm, a particle aspect ratio from about 1000 to about 2 and a thickness of from about 1 to about 500 μm; at least one cleansing agent select
1. A rinse-off skin care composition, comprising: hydrophobic, linear cellulose particles derived from cotton, having an average length of less than about 1000 tJm, a particle aspect ratio from about 1000 to about 2 and a thickness of from about 1 to about 500 μm; at least one cleansing agent selected from the group consisting of a saponified fat and a surfactant; and a cosmetically acceptable carrier, wherein said hydrophobic, linear cellulosic particles comprise a coating of a hydrophobic agent selected from the group consisting of metal soap, organic wax, synthetic wax, long-chain fatty acids, long-chain fatty esters, non-water soluble polymers, high molecular water-insoluble fluoropolymers and polymerized siloxanes, and wherein the water contact angle of said hydrophobic, linear cellulose particles is greater than about 90 degrees, and wherein the cellulose fibers are generated from cloth or nonwoven materials previously formed by cotton. 2. The rinse-off skin care composition according to claim 1 wherein said hydrophobic, linear cellulose particles have an oil absorption capacity and retention of from about 150 to about 500% weight oil/weight particles. 3. The rinse-off skin care composition according to claim 2 wherein said oil absorption capacity and retention of said hydrophobic, linear cellulose particles is from about 300 to about 500% weight oil/weight particles. 4. The rinse-off skin care composition according to claim 1 wherein said water contact angle is greater than about 100 degrees. 5. The rinse-off skin care composition according to claim 1 wherein said water contact angle is greater than about 120 degrees. 6. The composition according to claim 1 wherein said surfactant is selected from the group consisting of anionic, nonionic, and amphoteric surfactants. 7. The rinse-off composition according to claim 1 wherein said composition comprises from about 1 to about 20 percent by weight of said hydrophobic, linear cellulose particles. 8. The rinse-off composition according to claim 1 wherein said composition comprises from about 1 to about 10 percent by weight of said hydrophobic, linear cellulose particles. 9. The rinse-off composition according to claim 1 wherein said composition comprises from about 1 to about 6 percent by weight of said hydrophobic, linear cellulose particles. 10. The rinse-off skin care composition according to claim 1 wherein the aspect ratio of the hydrophobic, linear particle from about 200 to about 5. 11. The rinse-off skin care composition according to claim 1 wherein the length of the linear, hydrophobic particles is from about 10 to about 500 microns and the width of the hydrophobic linear particles is from about 5 to about 25 microns.
