Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to cosmetics, and more particularly, to cosmetics useful for preventing makeup collapse.

[0002]

2. Description of the Related Art Important factors such as make-up cosmetics include the fact that cosmetics are beautifully arranged on the skin and how long the finish of the makeup lasts as it was originally. It is difficult to say. This is because makeup makeup adheres to the skin only by physical force, so the degree of adhesion may be uneven depending on the condition of the skin and the local structure, or physical force or secretion from the living body This is because there are phenomena in which the position coordinates differ depending on an object or the like, and the optical properties change due to change in wetting. To prevent such a phenomenon,
Base cosmetics are being developed. In order to enhance the color rendering effect of cosmetics, the base cosmetics corrects skin color, acts as a binder between the cosmetics and the skin, firmly attaches the cosmetics to the skin, and wets the secretions with the cosmetics. It is a cosmetic that has the function of preventing it from reaching,
It did not have all of the above effects. A particular focus is on the ability to accurately place cosmetics on the skin (improvement of makeup glue). As a means to prevent makeup collapse, it is necessary to carry a makeup refill such as pressed powder, etc. , Make-up cosmetics themselves have been made less susceptible to makeup collapse. Typical types of base cosmetics in such a combination of cosmetics include a water-soluble gel preparation using a gel preparation of a carboxyvinyl polymer and / or a salt thereof, and an emulsion preparation using a carboxyvinyl polymer as a stabilizer. Is mentioned.

On the other hand, as factors on the skin side related to both makeup glue and makeup collapse, the presence of pores has recently been highlighted. In other words, the present inventors have found that pores are the largest element of the non-uniformity on the skin, and that makeup secretion is caused by secretions derived from living bodies secreted from the pores. It has also been found that by smoothly correcting such pores with a transparent powder, the makeup paste is remarkably improved. However, there is no known technique for using such a powder in combination with an acrylic water-based polymer partially having an alkyl group having 6 to 20 carbon atoms, and such a technique provides a fresh feeling of use and makes-up. It has not been known that when makeup is applied, a base cosmetic having little change over time in the cosmetic finish can be obtained.

[0004]

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION The cosmetic of the present invention contains a transparent powder as an essential component. The transparent powder can be used without any particular limitation as long as it is a light-transmitting powder and is used in cosmetics. For example, spherical, amorphous or flaky silicic anhydride, nylon or Examples thereof include polymer resin powder such as acrylic resin beads, calcium silicate or magnesium silicate, a methylsiloxane network polymer, and a crosslinked dimethylpolysiloxane. These transparent powders can be used as they are, or can be used after surface treatment. Examples of such surface treatment include baking treatment of hydrogen methyl polysiloxane, baking treatment of dimethyl polysiloxane, phosphate coating treatment such as sodium polyphosphate, silylation treatment with a silylating agent, and a compound having a perfluoro group. Processing can be exemplified. Each of these powders is a general-purpose raw material for cosmetics, and is obtained by purchasing a commercial product. Of these transparent powders, particularly preferred is silicic anhydride, and spherical silica is particularly preferred. These transparent powders have the effect of covering the pores and flattening the skin surface, and making changes in the makeup finish due to uneven makeup glue or makeup collapse. The total content of the transparent powder in the cosmetic of the present invention is preferably 1 to 20% by weight, more preferably 4 to 20% by weight.
１５15 weight. If the amount is too large, the effect will reach a peak or the shape stability will be adversely affected.If the amount is too small, the pores cannot be corrected, the cosmetic finish cannot be beautifully made, or makeup collapse will be prevented. Because they may not be able to do so.

The cosmetic of the present invention is characterized in that it contains an acrylic aqueous polymer partially having an alkyl group having 6 to 20 carbon atoms, in addition to the transparent powder. The aqueous polymer referred to in the present invention is a water-soluble polymer which is itself dissolved or transparently dispersed in an aqueous medium, and is not transparent but is uniformly dispersed in an aqueous medium such as water in the form of an emulsion or the like. This is a general term for the term "polymer emulsion". These can be present with a uniform probability in aqueous cosmetics, so that any of them can be used in the cosmetics of the present invention. Examples of such a polymer in a commercial product include water-soluble polymers such as Carbopol 1382 (manufactured by Goodrich Co.), which is an acrylic acid / alkyl (C10-30) acrylate copolymer, and acrylic acid. -Pemlen TR-1 or Pemlen TR-2 (manufactured by Goodrich Co.), which is a methacrylic acid (C10-30) alkyl copolymer, can be exemplified. As the polymer emulsion, acrylic acid / alkyl acrylate copolymer emulsion Polyjoint JN (manufactured by Taisei Kako Co., Ltd .; resin content 50% by weight), ethyl acrylate, methacrylic acid-2
Acryt SE-141, which is an acrylic acid / alkyl acrylate copolymer emulsion containing ethylhexyl, acrylic acid and lauryl methacrylate as constituent monomers
6AX2 (manufactured by Taisei Kako Co., Ltd .; resin content 24% by weight) is preferred. Among them, particularly preferred are polymer emulsions, and among them, Acryt SE-
1416AX2 is particularly preferred because the makeup is the most beautiful when makeup is applied on the cosmetic of the present invention. In the cosmetic of the present invention, the above-mentioned aqueous polymer may be contained solely or in combination of two or more. Further, these polymers can be used as salts with alkalis such as sodium and potassium, and such polymers and techniques also belong to the technical field of the present invention. Preferred content of these aqueous polymers in the cosmetic of the present invention,
Total amount in terms of resin content, 0.0
1 to 10% by weight, and more preferably 0.05 to 1% by weight.
% By weight. If the amount is too small, the fixation effect and the collapse prevention effect of the makeup cosmetic may be impaired,
If the amount is too large, an unpleasant feeling of use such as stickiness may be caused, or the makeup finish of the makeup cosmetic may become thick and the beauty may be impaired.

In the cosmetic of the present invention, besides the above-mentioned essential components, a transparent powder and an acrylic aqueous polymer having an alkyl group having 6 to 20 carbon atoms, a quince extract may be mentioned as a preferable component. I can do it. This is because the adhesiveness of the quince extract firmly adheres the makeup cosmetics and prevents makeup collapse. The preferred content of such quince extract is 0.1 to 10% by weight, more preferably 1 to 5% by weight.

[0009] As described above, the effect of the present invention is that the effect of the pore correction is that uniform makeup of the makeup cosmetic is applied to the skin and that the makeup is destroyed due to the change in the wetting of the cosmetic by the sebum secreted from the pores. From the viewpoint of prevention, it is preferable that the cosmetic of the present invention be an aqueous gel type having a small content of oils and fats. The content of fats and oils is preferably suppressed to 5% by weight or less. In addition, by making such a type, it is excellent in preventing makeup collapse caused by the wetting of biological secretions such as sebum and sweat, so that under makeup makeup in the summer season when such makeup collapse is likely to occur. Particularly preferred as a base cosmetic such as a control color. For this reason, it is preferable that an aqueous gelling agent indispensable for the aqueous gel formulation is contained in addition to the above-mentioned components. As such an aqueous gelling agent, a carboxyvinyl polymer and / or
Or a salt can be illustrated suitably. Preferred examples of such salts include alkali metal salts such as sodium and potassium, ammonium salts, and organic amine salts such as triethanolamine. The preferred content of such a gelling agent is preferably 0.1 to 10% by weight in terms of the amount of the polymer itself,
More preferably, it is 1 to 5% by weight. The neutralization rate is 10
~ 100% is preferred. When such a gel preparation is used as a base material for summer, it is preferable to contain a cooling agent in addition to the above components. This is because the secretion of sebum and sweat can be suppressed by the cooling agent, and the durability of makeup can be further improved. Examples of such a cooling agent include l-menthol, thymol, eucalyptus extract, bacolder extract and the like. These are preferably contained in an amount of 0.01 to 0.5% by weight.

The cosmetic of the present invention can contain optional components usually used in cosmetics, in addition to the above essential and preferred components. Such optional components include:
For example, hydrocarbons such as squalane, petrolatum, microcrystalline wax, etc., esters such as jojoba oil, carnauba wax, octyldodecyl oleate, triglycerides such as olive oil, tallow, coconut oil, stearic acid, oleic acid, ritinoleic acid Fatty acids such as oleyl alcohol, stearyl alcohol, higher alcohols such as octyl dodecanol, anionic surfactants such as sulfosuccinates and sodium polyoxyethylene alkyl sulfate, amphoteric surfactants such as alkyl betaine salts, and dialkylammonium salts Such as cationic surfactants, sorbitan fatty acid esters, fatty acid monoglycerides, polyoxyethylene adducts thereof, polyoxyethylene alkyl ethers, polyoxyethylene fatty acid esters, etc. Examples include on-surfactants, polyhydric alcohols such as polyethylene glycol, glycerin, and 1,3-butanediol, thickening / gelling agents, antioxidants, ultraviolet absorbers, coloring agents, preservatives, and powders. can do.

The cosmetic of the present invention can be produced by treating the above-mentioned components according to a conventional method. As described above, the cosmetic of the present invention is particularly preferably in the form of a base material used in a city. However, a cosmetic having a function of both a base material and a makeup cosmetic by adding a small amount of powder is preferred. Such cosmetics also belong to the cosmetics of the present invention. The thus obtained cosmetic of the present invention physically corrects pores, prevents makeup cosmetics from falling into the pores at the time of makeup makeup, and prevents the finish from being impaired by the localization of the cosmetics. It adsorbs and retains sebum and sweat secreted from pores, and has an excellent effect of preventing makeup collapse of a type in which pores are noticeable due to sebum or sweat.
