BACKGROUND OF THE INVENTION
The present invention relates to a cosmetic, and more particularly to a cosmetic suitable for point makeup.
[0002]
[Prior art]
For point makeup, cosmetics such as hair nail polish, nail color, nail coat, nail gloss, eye color, eye gloss, mascara, eyeliner, cheek color, lip color or lip gloss are known and their required qualities. In other words, it has a high color rendering effect and has physical properties that can be applied to a relatively narrow, small place uniformly and without spreading to other parts. Among these, for the realization of the color rendering effect, a glossy material such as a so-called lame agent such as a piece of laminated polymer film called glitter or a piece of polymer film deposited with metal or metal oxide is used. What you have is used. In order to realize the physical properties as described above, a high-viscosity liquid dosage form (Japanese Patent Laid-Open No. 2002-138017), a powder-shaped dosage form (Japanese Patent Laid-Open No. 2000-38315), or an oil gel dosage form ( JP 2000-309506) is used. However, these have problems such as the weight of spreading in coating, and the improvement thereof has been desired. The reason for this heavy weight is that the lame agent is thin and the area is larger than that of normal powder, so that the coefficient of friction is large, and the extension requires a larger stress than usual. It is done. That is, in a makeup for point makeup containing a lame agent, there has been a demand for a means to lighten the spread without impairing the cosmetic effect.
[0003]
On the other hand, no cosmetics for point makeup containing 35 to 50% by weight of oils and fats that are liquid at 1 atm and 25 ° C. are not known. This is because it was thought that bleeding was easily caused by containing liquid oil and fat at a high concentration, and it was not suitable for point makeup cosmetics.
[0004]
[Problems to be solved by the invention]
The present invention has been made under such circumstances, and it is an object of the present invention to provide a means for reducing the spread of cosmetics for point makeup containing a lame agent without impairing the cosmetic effect. To do.
[0005]
In order to solve the problems]
In view of such circumstances, the present inventors have intensively researched and sought for means for reducing the spread of cosmetics for point makeup containing a lame agent without impairing the cosmetic effect. As a result, in the cosmetics for point makeup, it was found that such an improvement can be achieved by containing 35 to 50% by weight of oils and fats that are liquid at 1 atm and 25 ° C., and the invention is completed. It came to. That is, this invention relates to the technique shown below.
(1) A cosmetic for solid point makeup, comprising 35 to 50% by weight of oil and fat that is liquid at 1 atm and 25 ° C.
(2) The cosmetic for solid point makeup according to (1), further comprising 5 to 20% by weight of lame powder.
(3) The cosmetic for solid point makeup according to (1) or (2), further comprising an oily gelling agent.
(4) The cosmetic for point solid make-up according to (3), wherein the oily gelling agent is a fatty acid ester of dextrin.
(5) The solid point make-up cosmetic according to (3) or (4), wherein the content of the oily gelling agent is 5 to 15% by weight.
(6) The cosmetic for solid point makeup according to any one of (1) to (5), further comprising 30 to 40% by weight of a powder other than a lame preparation.
(7) The cosmetic for point makeup according to any one of (1) to (6), wherein the cosmetic for point makeup is eye gloss.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
(1) Oils and fats that are essential components of cosmetics for solid point makeup according to the present invention The cosmetics for solid point makeup according to the present invention is preferably 35 to 50% by weight of oils and fats that are liquid at 1 atm and 25 ° C. Is characterized by containing 37 to 45% by weight. Such fats and oils have the above-mentioned physical properties and are not particularly limited as long as they are used in cosmetics. For example, carbonization of squalane, liquid paraffin, light liquid isoparaffin, heavy liquid isoparaffin, etc. Hydrogens, dimethicone, femethicone, cyclomethicone, amodimethicone, silicones such as polyether-modified silicone, octyldodecyl oleate, isopropyl myristate, neopentyl glycol diisostearate, esters such as diisostearate malate, Fatty acids such as oleic acid, isostearic acid and isopalmitic acid, higher alcohols such as oleyl alcohol and octadecyl alcohol, coconut oil, wheat germ oil, isostearic acid triglyceride, isooctanoic acid triglyceride, olive oil , Triglycerides such as (caprylic-capric acid) triglyceride can be preferably exemplified. Among these, hydrocarbons or triglycerides are preferable, and a particularly preferable form is a form containing (caprylic acid / capric acid) triglyceride, and a preferable content of such (caprylic acid / capric acid) triglyceride is Is preferably 5 to 15% by weight. These can contain only the seed | species, and can also be made to contain in combination of 2 or more type. Such fats and oils can contain only one species, or two or more species can be contained in combination. A combination of two or more types is more preferable than a single use in terms of improving the use characteristics and makeup effects such as long-lasting makeup. These fats and oils have the effect of 1) improving the spreading during use, and 2) improving the gloss characteristics of color materials such as lame agents.
[0007]
(2) Lame agent preferably contained in the cosmetic for the solid point makeup of the present invention The cosmetic for the solid point make of the present invention preferably contains a lame agent. Here, the lamellar agent means a flat powder having remarkably reflected gloss or interference gloss and can be used without particular limitation as long as it is used in cosmetics. For example, a thin film of polyethylene terephthalate or epoxy resin is used. Preferred examples include laminated small pieces, small pieces obtained by sandwiching a metal oxide coating layer on a thin film of polyethylene terephthalate or epoxy resin, and thin films of polyethylene terephthalate or epoxy resin deposited with a metal such as aluminum. Among these, preferable commercially available products include, for example, aluminum flake silver 0.01 (manufactured by Kakuhachi scales Co., Ltd.), diamond hologram HG-S40EP, diamond hologram HG-S60EP, DC glitter silver CNo. Suitable examples include 0.005 (manufactured by Dia Kogyo Co., Ltd.), MAu glitter (manufactured by Oike Kogyo Co., Ltd.), iridescent glitter IF-4101 (manufactured by Engelhard Corporation) and the like. In the cosmetic of the present invention, such a lame preparation can contain only one species or a combination of two or more species. The preferable content of the lame agent in the cosmetic of the present invention is 5 to 20% by weight, more preferably 8 to 15% by weight, based on the total amount of the cosmetic. This is because if the amount is too small, the makeup effect may be impaired. If the amount is too large, the makeup effect may reach its peak, and the degree of freedom of prescription may be impaired.
[0008]
(3) Oily gelling agent preferably contained in the solid point makeup cosmetic of the present invention The solid point makeup cosmetic of the present invention preferably contains an oily gelling agent. Here, the oil-based gelling agent is a general term for substances that are oil-soluble or oil-dispersible and have an action of gelling the oil phase by dissolving or dispersing in the oil phase.
