Packaged cosmetic compositions and related methods

1 . A packaged powder-to-liquid-to-powder cosmetic composition wherein the composition in the package is in the powder form and comprises a powder-to-liquid effective amount of at least one porous particulate having contained within at least one liquid solvent expressible from the particulate upon application of pressure; and the package comprises a container, and an applicator for the composition that is operable to pick up the composition in its powder form and upon application of the powder to the keratinous surface, exert pressure sufficient to express the liquid from the porous particulate causing the powder to form a liquid upon application to the keratinous surface, which dries to a powder finish.

2 . The packaged composition of claim 1 wherein the porous particulate is polymeric.

3 . The packaged composition of claim 1 wherein the porous particulate comprises cellulosics, crosspolymers, resins, silica, silicates, silicone elastomers, or mixtures thereof.

4 . The packaged cosmetic composition of claim 3 wherein the porous particulate comprises cellulosics, crosspolymers, or mixtures thereof.

5 . The packaged cosmetic composition of claim 4 wherein the cellulosics are homo- or copolymers of cellulose monomers that may be substituted with alkali or alkaline earth metals or C 1-10 alkyl or alkoxy groups.

6 . The composition of claim 6 wherein the cellulosic comprises starch or starch substituted with C 1-10 alkyl or alkoxy groups or alkali or alkaline earth metals.

7 . The composition of claim 1 wherein the porous particulate is starch, hydroxypropyl starch, hydroxyethyl starch, sodium carboxymethyl starch, aluminum starch octenylsuccinate, corn starch, rice starch, microcrystalline cellulose, maltodextrin, aluminum starch, dextran, glyceryl starch, or mixtures thereof.

8 . The packaged cosmetic composition of claim 1 wherein the porous particulate comprises a crosspolymer.

9 . The packaged cosmetic composition of claim 8 wherein the crosspolymer is a polymer of ethylenically unsaturated monomers.

10 . The packaged cosmetic composition of claim 9 wherein the crosspolymer is a polymer of acrylate or methacrylate monomers.

11 . The packaged cosmetic composition of claim 10 wherein the crosspolymer comprises methyl methacrylate crosspolymer.

12 . The packaged cosmetic composition of claim 1 wherein the porous particulates comprise a mixture of cellulosics and crosspolymers from ethylenically unsaturated monomers.

13 . The packaged cosmetic composition of claim 1 comprising about 2-98% by weight of the total composition of porous particulates.

14 . The packaged cosmetic composition of claim 1 wherein the porous particulates have a particle size ranging from about 20 to 1000 microns.

15 . The packaged cosmetic composition of claim 1 wherein the porous particulates have a porosity ranging from about 50 to 500 ml/100 grams.

16 . The packaged cosmetic composition of claim 1 wherein the porous particulates have a density ranging from about 0.08 to 0.55 g/cm 3 .

17 . The packaged cosmetic composition of claim 1 wherein the container comprises a compact, jar or bottle.

18 . The packaged cosmetic composition of claim 1 wherein the applicator comprises a brush, foam applicator, or sponge.

19 . The packaged cosmetic composition of claim 1 wherein the solvent comprises water either alone or in combination with one or more non-aqueous solvents which are silicones, hydrocarbons, esters, mono-, di-, or polyhydric alcohols, or mixtures thereof.

20 . The packaged cosmetic composition of claim 1 wherein the applicator is a brush.

21 . The packaged cosmetic composition of claim 1 which is a foundation, concealer, lipstick, eyeshadow, blemish treatment, or blusher.

22 . A packaged powder-to-liquid-to-powder cosmetic composition wherein the composition in the package is in the powder form and comprises a powder-to-liquid effective amount of a mixture of porous particulates, at least one of which has transfer resistant or long wearing properties, wherein at least one of the porous particulates has contained within at least one liquid volatile solvent expressible from the particulate upon application of pressure; and the package comprises a container, and a brush applicator for the composition that is operable to pick up the composition in its powder form and upon application of the powder to the keratinous surface, exert pressure sufficient to express the liquid from the porous particulate causing the powder to form a liquid upon application to the keratinous surface, which dries to a transfer resistant powder finish.

23 . The packaged cosmetic composition of claim 22 wherein at least one of the porous particulates comprises a silicone resin.

24 . The packaged cosmetic composition of claim 22 wherein the container is a jar having a lid with one or more pores.

25 . The packaged cosmetic composition of claim 24 wherein the powder can be shaken from the container through the lid with one or more pores upon manipulation of the container.

26 . The packaged cosmetic composition of claim 25 wherein the applicator is a brush made from synthetic fibers.

27 . A method for improving laxity and/or tone of skin comprising applying to said skin a composition one porous particulate having contained within at least one liquid solvent expressible from the particulate upon application of pressure, and upon application, providing pressure sufficient to express the liquid solvent from the porous particulate to form a liquid film on the skin that, when dry, improves the laxity and/or tone of the skin.

28 . A method for providing a transfer resistant or long wearing finish on skin by applying a color cosmetic composition containing at least one porous particulate having contained therein at least one liquid solvent expressible from the particulate upon application of pressure, and upon application, providing pressure sufficient to express the liquid solvent from the porous particulate to form a liquid film on the skin that dries to a transfer resistant or long wearing finish.
