Definitions

• This invention relates to cosmetic powders uti ⁇ lized in eye shadows, blushes, face powders, and other cosmetic uses wherein the primary component is a powder.
• pressed powder cake which is formed by compressing loose powder such as talc and mica into a cake formed in a metal pan under pressure and thereafter taking the pan and gluing it into a compact or other suitable packaging receptacle.
• composition and method of the present inven ⁇ tion utilizes cosmetic powder ingredients and calcium sul ⁇ fate hemihydrate in an aqueous dispersion of emollients by which the powder product may be molded without any
• the resulting product will accept decorative fin ⁇ ishes on the surface and most importantly can be poured, into* molds from the top. Any need for pressing and gluing or special grid systems is eliminated.
• the cosmetic powder composition of the present invention can be poured directly
• composition of the present invention permits the realization of varied shapes and surface finishes, greatly increasing the appearance characteristics of the
• composition of the present invention allows more emollients to be placed on the skin, which combats the drying effect
• the cosmetic powder composition of this invention is formed by combining a water-insoluble emollient with a blend of insoluble organic or inorganic cosmetic powders,
• the resulting products have excellent payoff characteristics in combination with desirable strength.
• composition may be poured directly into the top of a compact or pan receptacle and the hydration reac ⁇ tion allowed to take place. Excellent decorative and surface effects may be obtained.
• composition of the present invention results in:
• a suitable composition comprises a water insol ⁇ uble emollient such as isopropyl myristate, encapsulated mineral oil, white petrolatum, isopropyl palmitate, or 5. ethylhexyl palmitate in the amount of 5 - 10%, a surfactant in the amount of 1 - 8% (preferably 3 - 6%) to emulsify the emollient in water, calcium sulfate hemihydrate 8 - 20%, water 50 - 62%, and particulate material and other cosmetic ingredients 20 - 30% by weight. 10.
• Suitable surfactants by way of example only, are
• Tween 20 which is laurate esters of sorbitol and sorbitol anhydride, comprising mostly the monoester condensed with 20 moles of ethylene oxide; and Triton X-100, which is Octoxynol-9, an "ethoxylated alkylphenol of the formula 15. CgH ⁇ 7 CgH4 (OCH 2 CH2) n 0H ' where "n" has an average value of 9.
• the powder blend in a slurry form may be di ⁇ rectly poured into the top or front of the compact recep- 30. tacle or pan, hydration allowed to occur, and a fine ac ⁇ ceptable surface finish results.
• the slurry may be readily poured into various shaped molds, allowing greater flexibility and function for end products.
• a preferred representative embodiment or mode for carrying out the present invention was made by blending 54.25 parts deionized water with preservatives and antioxi- dants comprised of methylparaben, .16 parts; propylparaben,
• the speed of the hydration reaction may .be modified by adding appropriate amounts of known hydration accelerators or retardants.
• Usual additional cosmetic materials such as fragrances or micro-encapsulated oils and colorants may also be included.
• composition of the present inention provides an efficient and much less expensive way of manufacturing cosmetic powder products that have excellent strength and payoff characteristics, attractive surface appearance, and do not require compacting pressure, which is a primary
• composition also permits products to be formed by top pouring into various shaped molds or directly into cavities in the end product, such as compacts, and
• composition also is free of organic water-
