Abstract

Disclosed is a pressed powder composition having comprising by weight: (a) from about 75% to about 99% of a powder comprising: (1) at least 25% by weight of the entire composition of a high coverage pigment selected from the group consisting of titanium dioxide, zinc oxide, and mixtures thereof, (2) a natural mica selected from the group consisting of muscovite, phlogopite, mixtures thereof, and complexes thereof; the natural mica having a Natural Mica Percentage to the entire composition; (b) from about 1% to about 25% of a binder selected from the group consisting of non-volatile oil, lipophilic surfactant, humectant, solid fatty compounds, solid wax, solid gelling agents, solid silicone elastomers, and mixtures thereof; wherein the composition has a Product Oil Absorbency of from about 10 g/100 g to about 23 g/100 g, wherein the Product Oil Absorbency is the oil absorbency measured by JIS K5101 modified by: i) using the entire composition as a test sample; ii) using the binder as the oil to be absorbed; and iii) the unit transferred into g/100 g; wherein the composition has a Compaction Index of from about 25 to about 70, wherein the Compaction Index is described by the following formula: Compaction Index=2.69×Product Oil Absorbency+1.46×Natural Mica Percentage−31.44.

Claims

1. A pressed powder composition comprising by weight:

(a) from about 75% to about 99% of a powder comprising;

(1) at least 25% by weight of the entire composition of a high coverage pigment selected from the group consisting of titanium dioxide, zinc oxide, and mixtures thereof,

(2) a natural mica selected from the group consisting of muscovite, phlogopite, mixtures thereof, and complexes thereof;

the natural mica having a Natural Mica Percentage to the entire composition;

(b) from about 1% to about 25% of a binder selected from the group consisting of non-volatile oil, lipophilic surfactant, humectant, solid fatty compounds, solid wax, solid gelling agents, solid silicone elastomers, and mixtures thereof;

wherein the composition has a Product Oil Absorbency of from about 10 g/100 g to about 23 g/100 g, wherein the Product Oil Absorbency is the oil absorbency measured by JIS K5101 modified by;

i) using the entire composition as a test sample;

ii) using the binder as the oil to be absorbed; and

iii) the unit transferred into g/100 g;

wherein the composition has a Compaction Index of from about 25 to about 70, wherein the Compaction Index is described by the following formula;

Compaction Index=2.69×

Product Oil Absorbency+1.46×

Natural Mica Percentage−

31.44.

2. The composition of claim 1 wherein the Natural Mica Percentage is from about 1% to about 45%.

3. The composition of claim 1 wherein the Compaction Index is from about 35 to about 60.

7. A method of making up the skin comprising the steps of:

(1) providing a concealer and foundation according to claim 6;

(2) applying to the skin the foundation; and

(3) applying to the skin the concealer.

4. A pressed powder composition comprising by weight:

(a) from about 84% to about 94% of a powder comprising;

(1) from about 25% to about 50% by weight of the entire composition of a high coverage pigment selected from the group consisting of titanium dioxide, zinc oxide, and mixtures thereof;

(2) from about 10% to about 35% of a natural mica selected from the group consisting of muscovite, phlogopite, mixtures thereof, and complexes thereof;

(b) from about 6% to about 16% of a binder selected from the group consisting of non-volatile oil, lipophilic surfactant, humectant, solid fatty compounds, solid wax, solid gelling agents, solid silicone elastomers, and mixtures thereof;

wherein the composition has a Product Oil Absorbency of from about 10 g/100 g to about 23 g/100 g, wherein the Product Oil Absorbency is the oil absorbency measured by JIS K5101 modified by;

i) using the entire composition as a test sample;

ii) using the binder as the oil to be absorbed; and

iii) the unit transferred into g/100 g.

5. The composition of claim 4 wherein the powder comprises colored powders.

6. The composition of claim 5 which is a concealer to be used with a foundation, the foundation having a color, and wherein the CMC DE of the foundation color and the concealer color is less than 1.5.
