1. A leave-on skin care composition, comprising: a non-ionic emulsifier in an amount of from 0.5% to 2% by weight of the composition; and further comprising hydrophobic, linear cellulose particles having an average length of from about 2 to about 500 μm, a particle aspect ratio from about 2 to about 20, a width of from about 1 to about 25 μm; 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, said hydrophobic, linear cellulose particles have an oil absorption capacity and retention of from 150 to about 500% weight oil/weight particles and wherein the water contact angle of said hydrophobic, linear cellulose particles is greater than 90 degrees; and the hydrophobic, linear cellulose particles are derived from regenerated cotton. |
