TECHNICAL FIELD
The present invention relates to a pressed powder cosmetic composition which comprises a high level of moisturizing agent and has adequate cake hardness. The composition is particularly useful for make¬ up cosmetics such as powder foundation, eyeshadow, blusher, face powder, and powder lip.
BACKGROUND
Cosmetic compositions containing a high level (70% or more) of powder colorants are known as pressed powders and are typically made by spraying a binder base consisting essentially of oily materials onto the powder colorants and pressing into a cake. These pressed powder cosmetic compositions are generally known to cause drying of skin due to moisture take-up or absorption by the powder colorants from the surface of the skin. However, when an effective amount of moisturizing agent is incorporated in a composition with high level of powder colorant, the moisturizing agent agglomerates the powder colorants. Consequently, the product which has then been pressed into a cake becomes unacceptably hard. It is known in the cosmetic art that pressed cosmetic cakes which are too hard have a solid and slippery surface, and thus are difficult to take-up with an applicator, and also show a negative shiny, glossy appearance (known in Japanese as "tsunobikari") . Cake hardness can be roughly measured by a Penetrometer of Japanese Industrial Standard. For powder foundation cosmetics, it is generally known that those having a penetration of 15-25 units give adequate hardness. Ultimately, adequate hardness is determined by actual application of the product using the appropriate applicator for each product type.
Further attempts have been made to formulate pressed powder cosmetic compositions which provide moisturizing effect to the skin.
Patent Laid-open H2-157208 discloses a solid powder cosmetic comprising: (A) 70-99% powder; (B) diglyceride which is in liquid form at room temperature; and (C) polyol moisturizing agent freely soluble with component (B) ; wherein the weight ratio of component (B) : (C) is within th range of 10:1 - 1:20, and wherein the total of components (B) and (C) is 1-30%.
Patent Laid-open H2-152917 discloses a solid powder cosmetic comprising: (A) 70-99% powder; (B) oil which is in liquid form at room temperature; and (C) liquid surfactant which is insoluble with component
comprising: (A) 70-99% powder; (B) oil which is in liquid form at room temperature; and (C) liquid surfactant which is insoluble with component (B) at room temperature; wherein the weight ratio of component (B) : (C) is within the range of 20:1 - 1:2, and wherein the total of components (B) and (C) is 1-30%. Moisturizing agent is disclosed as an optional component, however there is no disclosure on the method of incorporating a moisturizing agent .
However, these attempts are not believed to be completely effective for providing a composition comprising an effective amount of moisturizing agent and adequate cake hardness .
Here it has been found that by making a binder base comprising a mixture of a nonionic surfactant and a moisturizing agent, a composition can be made which comprises a high level of moisturizing agent and also retains adequate hardness when pressed into a cake. More specifically, the present composition can comprise up to 15% moisturizing agent without making the obtained pressed cake too hard.
OBJECT OF INVENTION
It is an object of the present invention to provide a pressed powder cosmetic composition which comprises a high level of moisturizing agent and has adequate cake hardness.
It is also an object of the present invention to provide a pressed powder cosmetic composition which has good adhesion and durability on the skin.
It is also an object of the present invention to provide a process for making powder foundations wherein the binder base comprising moisturizing agent is stable and easy to handle.

Antioxidants and preservatives can be, and usually will be formulated in the composition of the present invention. Useful antioxidants and preservatives are tocopherol, dibutylhydroxy toluene, methylparaben, and propylparaben. These components are typically individually present at levels less than 1 %.
Useful skin conditioning agents are beta-glycyrrhetic acid and its derivatives, vegetation extracts, alantoin, collagen, and extract and treated elastin fibers. ERΩ£E≤
The present composition is made by first preparing a binder base by mixing nonionic surfactant and moisturizing agent, and optionally an oily material.
In one embodiment of the present invention, the binder base comprises 2-15% moisturizing agent and 0.4-15% nonionic surfactant, wherein said nonionic surfactant is at least one fifth by weight of moisturizing agent . With this amount of nonionic surfactant against moisturizing agent, the obtained binder base can hold a substantial ratio of moisturizing agent, up to 15% to the composition. In this embodiment, moisturizing agent, nonionic surfactant, and other components of the binder base can be mixed in any convenient manner to form a binder base which is suitable for spraying onto or kneading with the powder colorants.
In another embodiment of the present invention, the binder base comprises 0.1-15% moisturizing agent and nonionic surfactant respectively, and is in the form of a lipophilic gel. Such lipophilic gel binder base can be made by gradually adding the moisturizing agent into the nonionic surfactant or mixture of nonionic surfactant and optional oily material. Mixing can be done by a preferred mixer in the cosmetic art such as Anchor-type, Daysolver, Homomixer, and combinations thereof. The lipophilic gel binder base herein obtained has a lipophilic gel structure having a resistivity of at least about 10,000 omega*cm at room temperature. Resistivity can be measured, for instance by a resistivity measurer Type MR-45, Class 2.5 (Okasawa-denki) . Such lipophilic gel structure is different from water-in-oil or oil-in-water emulsions. This lipophilic gel binder base is stable in phase, and does not separate for at least a few hours at room temperature. This is important and useful, because this lipophilic gel binder base does not
have to be repeatedly mixed while spraying onto or kneading with the powder colorants. Further, since this lipophilic gel binder base is homogeneous, a pressed powder product of uniform composition is obtained, thus providing an adequate hardness to the pressed cake. It has been found that when components of the binder base are not uniform and/or are separated in phase, the obtained cake tends to become too hard. The components of the lipophilic gel binder base are preferably made in one of the following ways: i) gradually adding moisturizing agent into nonionic surfactant; ii) gradually adding moisturizing agent into nonionic surfactant, followed by adding obtained mixture into oily material; or iii) mixing nonionic surfactant and oily material, followed by gradually adding moisturizing agent into obtained mixture.
The binder base thus obtained by either embodiment of the present invention is then mixed with the powder colorant. This can be done by spraying the binder base onto the powder colorant while tumbling. The powder colorants are preferably pulverized before spraying on the binder base. (In the context of the present invention, "pulverizing" particularly pertains to deagglomerating particles to their original size) . If the binder base is too viscous to handle by spraying, the binder base can be kneaded with the powder colorants, and pulverized afterwards . After the powder colorant and binder base are mixed, the obtained composition is de-agglomerated and sifted to obtain consistent particle size, poured into a mold, and pressed into a cake. The whole composition making process, namely; preparing the binder base, spraying, pulverizing and pressing; can be done at room temperature.
Any optional components are incorporated in the composition of the present invention by dissolving or dispersing in a suitable phase in which it has affinity. Oily material can be used to make the lipophilic gel binder base, or otherwise, mixed with the powder colorants independently. Oily material can be independently mixed before or after the binder base (comprising moisturizing agent and nonionic surfactant) is mixed with powder colorant. Other lipophilic optional components can be dissolved or dispersed with powder colorants or liquid oils. Water and other hydrophilic optional components can be dissolved or dispersed with moisturizing agents.
