Abstract
The present invention is for powder compositions containing high levels of talc, low levels of titanium dioxide and a sebum absorbing material wherein the composition has improved skin coverage, uniformity and duration of wear. The invention can be used in formulating numerous cosmetic powder compositions such as eye shadow, foundation, loose powder and the like.
Claims20
A powder cosmetic composition comprising talc wherein said talc comprises:
- a. a first talc having a particle size distribution wherein no more than about 45% of the particles are 10 microns or less, no more than about 70% of the particles are 15 microns or less and no more than 85% of the particles are 20 microns or less;
- b. a second talc having a particle size distribution wherein no less than about 55% of the particles are 10 microns or less, no less than about 80% of the particles are 15 microns or less and no less than about 90% of the particles are 20 microns or less;
- wherein the ratio of said first talc to said second talc is from about 1:1 to about 6:1;
- and
- c. a sufficient amount of an sebum absorbing material capable of absorbing from about 0.2 grams of sebum per gram of material (g.sub.sebum /g.sub.material) to about 3.5g.sub.sebum /g.sub.material.
A powder cosmetic composition comprising talc wherein said talc comprises:
- a. a first talc having a particle size distribution wherein no more than about 40% of the particles are 10 microns or less;
- no more than about 65% of the particles are 15 microns or less and no more than 80% of the particles are 20 microns or less;
- b. a second talc having a particle size distribution wherein no less than about 60% of the particles are 10 microns or less, no less than about 85% of the particles are 15 microns or less and no less than about 95% of the particles are 20 microns or less;
- wherein the ratio of said first talc to said second talc is from about from about 2:1 to 4:1;
- and
- c. a sufficient amount of an sebum absorbing material capable of absorbing from about 0.8 grams of sebum per gram of material (g.sub.sebum /g.sub.material) to about 2.6g.sub.sebum /g.sub.material.
A powder cosmetic composition comprising talc wherein said talc comprises:
- a. a first talc having a particle size distribution wherein no more than about 35% of the particles are 10 microns or less, no more than about 60% of the particles are 15 microns or less and no more than 75% of the particles are 20 microns or less;
- b. a second talc having a particle size distribution wherein no less than about 65% of the particles are 10 microns or less, no less than about 90% of the particles are 15 microns or less and no less than about 100% of the particles are 20 microns or less;
- wherein the ratio of said first talc to said second talc is from about from about 3:1;
- and
- c. a sufficient amount of an sebum absorbing material capable of absorbing from about 1.5 grams of sebum per gram of material (g.sub.sebum /g.sub.material) to about 2.0g.sub.sebum /g.sub.material.
