Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a make-up cosmetic composition, and more particularly to a make-up cosmetic composition having an excellent effect of making structural defects of the skin such as pores, rough textures and fine wrinkles invisible.

[0002]

2. Description of the Related Art Conventionally, in makeup cosmetics, as powder raw materials, coloring pigments such as iron oxide, titanium oxide and zinc white, extender pigments such as mica, talc and sericite, and Such composite pigments and the like are blended, and a cosmetic having a good feel and a cosmetic effect is obtained depending on the combination and blending ratio of these.

However, plate-like extender pigments such as mica, talc, and sericite have a suitable sliding on a smooth flat surface without unevenness because the sliding direction is only horizontal to the flat surface due to their shape. However, the powder spreads evenly, but on a surface having irregularities, the powder falls to the concave portions, the slippage stops at the convex portions, and the powder accumulates at the root portion. Therefore, the makeup cosmetics containing these plate-like extender pigments can form a beautiful makeup coating film in a portion where skin unevenness is small, but for a portion having small wrinkles or rough texture, large pores, etc. Powder cannot be accumulated on textures and pores, or it may be caught by wrinkles, and a uniform and beautiful cosmetic coating cannot be formed.

Further, when spherical particles such as nylon powder and spherical silica are used in combination with the extender pigment, slipperiness due to rolling of the spherical particles is imparted, so that unevenness of the cosmetic material in the uneven portion is reduced. , The makeup coating looks more uniform and beautiful. However, it is hard to say that the structural irregularities are still difficult to see, and since the adhesiveness is impaired, makeup makeup easily occurs over time.

That is, it is very difficult to sufficiently make the structural defects of the skin such as pores, rough texture, fine wrinkles and the like in the makeup cosmetics containing the conventional extender pigments, which further satisfies these. Development of cosmetics is desired.

[0006]

In view of the above-mentioned circumstances, the present inventors can form a more uniform makeup coating film on uneven portions of the skin, and make it difficult to sufficiently see the structural defects of the skin such as rough texture and fine wrinkles. As a result of intensive studies on whether or not it is impossible to do, powders that have sufficient slipperiness even on uneven parts of the skin, spreadability due to rolling, and have sufficient adhesiveness can be effectively incorporated into makeup cosmetics. For example, makeup cosmetics that satisfy these requirements, and that make-up cosmetics in which an oil agent having a higher affinity for the skin is effectively mixed, are more effective in making the structural defects of the skin less visible. It was found that the number increased, and the present invention was completed.

That is, claim 1 of the present invention contains 0.5 to 30% by weight of a silicone powder granule containing silicone oil, (sum of compounding amounts of titanium oxide and zinc oxide) /
(Mixing amount of silicone powder granules) <2.5 is a makeup cosmetic.

A second aspect of the present invention is a makeup cosmetic composition according to the first aspect, which contains 0.5 to 20% by weight of a polyhydric alcohol.

A third aspect of the present invention is the makeup cosmetic composition according to the second aspect, wherein (amount of polyhydric alcohol blended) / (total amount of blended oil)> 0.2. Is.

The structure of the present invention will be described in detail below.

Silicone powder granules containing silicone oil are a characteristic component of the present invention. Its shape is spherical 1
It is an aggregate of 100 μm primary particles, and this aggregate has elasticity. When applied on the skin, the agglomerates are pressed against the skin by the pressure of the application and at the same time undergo a rolling-like disintegration. Therefore, if the coating pressure is applied diagonally above the coating surface during coating, the powder near the interface with the coating surface will adhere to the coating surface, and the powder on the top will move immediately to the next horizontal position. I will do it. By repeating this cycle, proper adhesion and uniform dispersion of powder are both achieved. In addition, since this silicone powder granule has elasticity, even when it is applied to the concave and convex portion, it expands and contracts on the respective surfaces of the concave and convex portions, so that the above-described property of simultaneous pressing and collapse is lost. It is not something that can be seen. Therefore, the silicone powder granules have a function of imparting to the cosmetic of the present invention a quick and uniform spread on the skin and an appropriate adhesiveness.

Such a silicone powder granule is a cured organopolysiloxane containing silicone oil. The silicone oil that constitutes the silicone powder granules is not particularly limited, but it is particularly preferable that it is a liquid at room temperature and has a viscosity at 25 ° C. of 10 to 1000 centistokes. The organopolysiloxane cured product is not particularly limited as long as it forms an agglomerate with spherical primary particles, but a dimethylsilicone crosslinked elastic material formed into spherical fine particles is preferable. Examples of materials that are suitable for this include Trefil E-505C manufactured by Toray Dow Corning Silicone Co., Ltd., and the like.

The amount of the silicone powder granules to be added to the makeup cosmetic of the present invention is preferably 0.5 to 30% by weight, more preferably 3 to 15% by weight. If it is less than 0.5% by weight, the blending ratio with respect to other powders becomes small, so that the effect due to the blending of the silicone powder granules cannot be sufficiently imparted to the makeup cosmetic, and if it exceeds 30% by weight, the silicone powder granules. Due to the elasticity of, the shapeability of makeup cosmetics is impaired.

The blending amount of the silicone powder granules in the makeup cosmetic of the present invention is also defined by the following ratio of the sum of the blending amounts of titanium oxide and zinc oxide and the blending amount of the silicone powder granules. That is, the ratio is (sum of blending amounts of titanium oxide and zinc oxide) / (blending amount of silicone powder granules)
<2.5. If this ratio is higher than this, titanium oxide or zinc oxide will increase the frictional resistance with the skin and deteriorate the slipperiness.

The polyhydric alcohol of the present invention is a compound having two or more hydroxyl groups in the molecule and has a higher polarity than other cosmetic oils, and therefore has a high affinity to the skin via the moisture on the skin. It has very high characteristics. Therefore, it becomes a component that further promotes the adhesion property of the silicone powder granules of the present invention to the skin, and the cosmetic of the present invention does not impair the slipperiness on the skin, and rough texture, small wrinkles, and exfoliation of keratin. It has the function of improving the adhesion to the affected areas and at the same time imparting proper skin familiarity. The polyhydric alcohol is not particularly limited as long as it is usually used as an oil agent for cosmetics.
Suitable for this are, for example, propylene glycol,
Examples include dipropylene glycol, 1,3-butylene glycol and glycerin.

The amount of polyhydric alcohol to be added to the makeup cosmetic of the present invention is 0.5 to 2 in the total makeup cosmetic.
0% by weight is preferable, and 1 to 10% by weight is more preferable.
Is. If it is less than 0.5% by weight, sufficient adhesiveness is not imparted, and if it exceeds 20% by weight, the effect appears as frictional resistance and the spread on the skin becomes heavy.

Further, the makeup cosmetic of the present invention can be made to have a more preferable effect by specifying the blending amount of the polyhydric alcohol in a constant ratio in relation to the whole oil agent. That is, the ratio is (the amount of the polyhydric alcohol blended) / (the sum of the amounts of the oil agent blended)> 0.2
Is. When this ratio is 0.2 or less, the cosmetic is not sufficiently compatible with the skin, and the adhesiveness between the cosmetic coating and the skin is slightly inferior. On the other hand, when it exceeds 0.2, a better makeup coating film with less change with time such as makeup deterioration is formed on the skin.

The make-up cosmetic composition of the present invention may contain a powder component used in ordinary cosmetic compositions. For example, iron oxide, titanium oxide, zirconium oxide, zinc oxide, alumina, magnesium oxide, barium sulfate, mica, talc, sericite, kaolin, ultramarine, navy blue, calcium carbonate, titanium mica, tar pigments, natural pigments, acrylic resin powder , Polymethylmethacrylate powder, nylon powder polymethysessesquioxane powder, silicic acid anhydride, coated mica with mica surface coated with titanium oxide, etc., coated nylon powder with similar coating treatment, coated polymethylmethacrylate, etc. Composite powder etc.

The makeup cosmetic of the present invention may contain an oily component used in ordinary cosmetics. For example, hydrocarbons such as petrolatum and liquid paraffin; aliphatic such as stearic acid and oleic acid; higher alcohols such as cetanol; esters such as isopropyl myristate; lanolin derivatives; silicone oils and derivatives thereof.

The makeup cosmetic of the present invention may further contain a surfactant, an antiseptic, an antioxidant, a fragrance, and
Moisturizers, bactericides, astringents, ultraviolet absorbers and the like can also be appropriately added within the range where the object of the present invention is achieved.
