Description

MAKEUP COMPOSITION FIELD OF THE INVENTION The present invention relates to a makeup composition comprising a tallow solidifying powder and an inorganic oil absorbing powder for improving the control of sebum. The compositions of the present invention are particularly useful for different forms of make-up base.
BACKGROUND OF THE INVENTION Make-up base compositions can be applied to the face and other parts of the body to match skin tone and texture and also to hide pores, imperfections, fine lines and the like. A make-up composition can also be applied to moisturize the skin, balance the oil content of the skin and to protect against the adverse effects of sunlight, wind and other environmental factors. Make-up base compositions are generally available in the form of liquid or cream suspensions, emulsions, compact powders or anhydrous oil and wax compositions. Emulsion type makeup bases in liquid form are suitable for their moisturizing effects, due to their aqueous or soluble skin treatment agents in water Make-up base compositions in solid form, including water-in-oil emulsion, are also suitable. Said solid emulsion makeup bases serve to cover the deficiencies of the makeup bases in liquid form and the conventional solid makeup bases. These make-up bases can be presented in a wide variety of packaging, including powders, and are increasingly popular with consumers. The references which these make-up base compositions disclose include Japanese Patent Publication Nos. A-2- 88511, A-3-261707, A-7-267819, A-11-209243; the U.S. patent no. 5,362,482; and the PCT publication WO 01/91704. Recently, consumers have begun looking for makeup foundations that have a sebum control benefit, and that also have hydrating benefits. Powders are known that have the benefit of controlling sebum. Finding a balance between the benefit of sebum control and the moisturizing benefit is still a challenge. In solid or liquid emulsion forms, the incorporation of a significant amount of sebum controlling powders is difficult due to the limited amount of total powders that can be incorporated into the composition. In addition, the decrease of other components can affect the composition's spreading characteristics. In powdered forms, the incorporation of a large quantity of effective sebum controlling powders can be technically possible; however, this can cause a composition to cause an unwanted sensation of dryness and tension in the skin.
Based on the foregoing, it is necessary to develop a make-up composition that provides a greater benefit of sebum control, and at the same time provides good spreading and moisturizing to the skin and leaves it clearer and with a feeling of freshness. None of the existing industries provide all the advantages and benefits of the present invention.
BRIEF DESCRIPTION OF THE INVENTION The present invention is directed to a makeup composition comprising, by weight: From about 1% to about 20% of a tallow solidifying powder comprising a base substance having a hydroxyapatite coated on the base substance, and an oxide of zinc fixed to the coating layer of the hydroxyapatite, wherein the zinc oxide is from about 15% to about 25% by weight of the tallow solidifying powder; from about 1% to about 10% of an inorganic oil absorbing powder having an oil absorbency of at least about 200 me / 100 g, wherein the weight ratio between the sebum solidifying powder and the absorbing powder of inorganic oil varies from about 1: 1.5 to about 20: 1; and a suitable carrier.
By formulating powders of certain characteristics in an adequate amount and proportion, a make-up composition that provides a sebum control benefit also provides good spreading and moisturizing to the skin and leaves it clearer and with a feeling of freshness. These and other attributes, aspects and advantages of the present invention will be apparent to those with experience in the industry from reading the present disclosure and the appended claims.
DETAILED DESCRIPTION OF THE INVENTION While the invention concludes with the claims that in particular indicate and claim the invention in detail, it is considered that it will be better understood from the following description. All percentages, parts and proportions are expressed based on the total weight of the compositions of the present invention, unless otherwise specified. Since they correspond to listed ingredients, all these weights are based on the level of assets and therefore do not include carriers or by-products that can be included in the materials available in the market. All the ingredients, for example, the active ingredients and others that are used in the present, can be classified by categories or described here according to their cosmetic or therapeutic benefits or according to their mechanism of described action. However, it should be understood that the active and other ingredients useful herein may in some cases provide more than one cosmetic and / or therapeutic benefit or may act through more than one mechanism. Therefore, in the present classifications are made for convenience and are not intended to limit an ingredient to the application especially mentioned or the applications listed. SEBO SOLIDIFYING POWDER The present composition comprises from about 1% to about 20% of a tallow solidifying powder comprising a base substance having a hydroxyapatite coated on the base substance, and a zinc oxide attached to the coating layer of the substance. hydroxyapatite, wherein the zinc oxide is present from about 5% to about 25% by weight of the tallow solidifying powder. By incorporating it into solid and liquid, water-in-oil emulsion forms, the composition comprises from about 1% to about 15%, preferably from about 2% to about 7%, of a tallow solidifying powder. The sebum solidifying powders useful herein are those which have a shape similar to that of a platelet, and which are coated with zinc oxide of low crystallinity, amorphous zinc oxide, or mixtures thereof. The relationship between zinc oxide and powder is important to provide a sebum solidifying effect. The base substance can be any organic or inorganic substance that is useful for cosmetic use, including those listed below under the heading "Component of dust". The tallow solidifying powder mentioned herein can be suitably manufactured in accordance with the methods set forth in U.S. Pat. no. 2002/0031534 A1, incorporated herein by reference. The surface of the tallow solidifying powders can be treated. The tallow solidifying powders useful herein have the ability to solidify tallow, ie, they are effective to absorb free fatty acid, diglyceride and triglyceride, and to solidify them by forming zinc salts thereof, such that forms a movie within a period of approximately 30 minutes. What's more, the originally glossy sebum changes its appearance and becomes a matte color film. This capacity can be distinguished from other oil-absorbing powders, which are not selective in the type of oil they absorb and do not form a film after absorbing an oil, and thus can leave shiny gels and pastes after absorbing the sebum. The change in appearance gives the user an obvious sign that sebum has been controlled. The solidifying effect of sebum can be measured easily by mixing a certain amount of powder with a certain amount of artificial sebum during a given period, and letting it rest until it has a solidified or matte color. The time it takes the mixture to solidify or change its appearance is recorded. The less time it takes to solidify or change color, the higher the solidifying effect of the powder.
Surprisingly, it has been found that, when combined with the aforementioned inorganic oil absorbing powder, the sebum solidifying effect of the tallow solidifying powder increases. Specifically, the combined use of a certain total weight of the tallow solidifying powder and the inorganic oil absorbing powder increases the solidifying effect of the tallow, as compared to the use of the same total weight of the tallow solidifying powder alone. This is unforeseen, given that it is known that oil absorbing powders do not necessarily contribute to the solidification of sebum. What is also unforeseen is that said increase is more significant in the inorganic oil absorbing powders. Therefore, the present composition provides a greater sebum control benefit despite the fact that the level of sebum controlling powders is relatively low. By keeping the level of sebum controlling powders low, the entire composition maintains the flexibility to adapt to other components that provide basic functions of a makeup composition. This is particularly true for the water-in-oil compositions herein. In water-in-oil compositions, the total amount of powder component is preferably kept low. By keeping the powder component level low, the entire composition maintains the flexibility to adapt to other components that provide spreading, wetting, lighter skin and a fresh feeling. Commercially available spherical oil absorbing powders useful herein include mica coated with hydroxyapatite, % zinc oxide with the trade name PLV-20, and the same powder surface treated with methicone under the trade name SI-PLV-20, both distributed by Miyoshi Kasei, Inc.

The oil absorbency is a unit known to those experienced in the industry and can be measured by the "Test method for the level of oil absorbency", JIS K5101 no. 21. The inorganic absorbent powders useful herein They include silica, silicate salts, carbonate salts, metal oxides, and hydroxyapatite.
