PURPOSE:To provide the titled cosmetic containing powder and an oil phase having a specific viscosity, separable into an upper oil phase and a lower pow der phase out of use when placed on a table, forming a uniformly dispersed liquid by shaking and mixing the components in use and giving beautiful make-up effect. CONSTITUTION:A two-layered liquid make-up cosmetic containing an oil phase (e.g. liquid paraffin, minke oil, oleic acid, etc.) having a viscosity of <=500cps. at 25 deg.C and powder (e.g. talc, kaolin, silica, alumina, titanium oxide, etc.) Addi tion of a volatile oil component having a boiling point of <=260 deg.C under atmo spheric pressure to the oil phase gives a cosmetic having smooth spreadability on the skin, giving no load to the skin, giving refreshing feeling after application and having improved water-resistance, oil-resistance and sebum-resistance. The water-resistance, oil-resistance and sweat-resistance can be further improved by the combined use of a silicone oil and a silicone resin as the oil component and the redispersibility of the powder can be improved compared with a cosmet ic containing other oil component.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is characterized in that when it is placed on a table when not in use, the upper layer becomes an oil layer,
The lower layer is divided into a powder layer, and when shaken during use, the two layers mix and disperse uniformly, creating a liquid form.It spreads extremely lightly during use, and when applied to the skin, it does not put any burden on the skin. The present invention relates to a new two-layer makeup cosmetic with a beautiful finish and excellent water resistance and sweat resistance.

[Prior Art] Conventionally, two-layer makeup cosmetics include water powder, which has been used for a long time. When this product is left still, the upper layer is separated into a water layer and the lower layer is a powder layer, and when shaken during use, they mix and form a uniformly dispersed liquid. This type of product contains a large amount of water, so it spreads easily (and has a refreshing, light feel), but it is made of water, powder, moisturizer, mucilage, etc., and does not contain oil. As a result, the finish was powdery, and the water and sweat resistance over time was extremely poor.

On the other hand, it has good water resistance, sweat resistance, and a non-powdery finish, with a solid oil content of 30%.
~80% by weight (hereinafter referred to as %), powder layer is 70% ~20%
There is a cosmetic called % oil-based solid cosmetic, which consists of powder, liquid oil, and solid oil such as wax.
0"It is heated at 0 to 90°C and poured into a medium plate or stick mold and allowed to cool and solidify. Since this is a type that solidifies with solid oil, 1. It spreads easily and is difficult to apply to the skin. When doing so, there is a drawback that it puts a burden on the skin.

[Problems to be solved by the invention] As a result of intensive research by the present inventors in order to obtain a make-up cosmetic that eliminates the above two types of drawbacks and makes use of only the advantages, the present inventors have developed an oil layer with an oil layer of 500 cps or less at room temperature. A two-layer liquid cosmetic that contains powder and separates into two layers (oil layer and powder layer) when left still, and mixes and forms a uniformly dispersed liquid when shaken during use. Compared to solidified oil-based cosmetics, it spreads extremely easily.
It does not put a burden on the skin when applied to the skin, and is water resistant and lT resistant compared to water-based two-layer liquid cosmetics consisting of water stone and a powder layer.
They found that it has extremely strong properties and a clean finish without powdery appearance, and based on this knowledge, they completed the present invention.

[Means for Solving the Problems] The present invention provides a two-layer liquid make-up cosmetic composition containing Urawa having 500 cps or less at 25°C and powder.

The configuration of the present invention will be described below.

Powders used in the present invention include inorganic powders such as talc, kaolin, mica, clay mineral powders such as bentonite, montmorillonite, silica, alumina, barium sulfate,
Calcium phosphate, calcium carbonate, titanium oxide, silicone oxide, zinc oxide, iron oxide pigments, ultramarine blue, navy blue,
These include chromium oxide, chromium hydroxide, cobalt oxide, and various pearl pigments. It is also possible to use powders that have been hydrophobized by silicone treatment, fatty acid treatment, metal soap treatment, dextrin-IJ fatty acid ester treatment, dibenzylidene sorbitol treatment, etc. of these powders.

These treatments can further improve makeup durability such as water resistance, sweat resistance, and sebum resistance.

In addition, organic powders include polyester, polyethylene,
Polystyrene, methyl methacrylate resin, cellulose,
Examples include nylon 12, nylon 6, copolymers of styrene and acrylic acid, polypropylene, vinyl chloride, and Teflon pigments.

In the cosmetic of the present invention, one or more of the above-mentioned inorganic powders and organic powders may be selected and used.

The total powder amount of the formulation (2) is 5 to 60% of the total amount of the cosmetic. If the total amount of powder is less than 5%, it is not preferable because it will be too thin and the makeup effect will not be felt. Moreover, if it exceeds 60%, the viscosity becomes too high and it becomes impossible to obtain a light and smooth spread, which is not preferable.

The oils used in the present invention include liquid paraffin, aliphatic hydrocarbons such as squalane, minkura, olive oil, jojobaura,
Animal and vegetable oils such as castor oil and lanolin, esters such as isopropyl myristate, octyldodecyl myristate, trimethylolpropane triisostearate, diisostearyl malate, higher alcohols such as isostearyl alcohol and oleyl alcohol, oleic acid, Higher fatty acids such as isostearic acid, isoparaffins with a boiling point of 260°C or less, such as Isopar (registered trademark) A and C
1, E, G, i1, K, Mashi, M (Exxon), Shellzol (registered trademark) 71 (Shell), Tsurutrol (registered trademark) 100, 130, 220 (
Philips Co., Ltd.), silicone oil represented by the following general formula (1) or (II), etc.

In the present invention, one or more of these oils may be appropriately selected and used.

(In the formula, n is an integer from 0 to 250, R represents a hydrogen atom, a lower alkyl group, or a phenyl group) (In the formula, n is an integer from 3 to 6, R represents a hydrogen atom or a lower alkyl group) (The following Margin) For the purpose of adjusting the usage level, one or more lower alcohols having 1 to 5 carbon atoms may be blended.

The viscosity of the above-mentioned oil (including alcohol) ranges from low viscosity to high viscosity, but it is an essential requirement of the present invention that the viscosity of the oil phase constituted by the oil is 500 cps or less at room temperature. The viscosity oil may be blended as long as the viscosity of the entire oil phase is 500 cps or less at room temperature.

Similarly, it is possible to blend a resin etc. that dissolves in the above-mentioned oil as long as the viscosity of the blended Urawa is 500 cps or less at room temperature.

The resin mentioned here includes general oil-soluble resins, such as aromatic hydrocarbon resins (Nippon Oil Co., Ltd.'s Nisseki Neopolymer T, 120.140, etc.) and terpene resins (Nippon Zeon Co., Ltd.'s Nisseki Neopolymer T, 120.140, etc.). Quintone A-100, B
-170, C-100, etc.), Bolybdenum (Idemitsu Oil Co., Ltd.'s Polybutyn 200, etc.), Polyisoprene (Exxon's Niscolera 1071U, 1) 03U, etc.), Alkyd resin (Dai-Nippon Ink Co., Ltd.'s Pescosol EL801), Solisodovesoko Zuru Nao 31, floor 96), PVP modified bomber (Gokyo Sangyo Co., Ltd.'s Ganex V-216, V-220)
), silicone resin (Shin-Etsu Chemical Co., Ltd.'s KR-285, KR
-278, KR-266, KR-1)4), and the like.

Among the above resins, silicone resins are 5i02, R31O3
/2 is a copolymer consisting of one or more structural units called R2SiC (R represents hydrogen, a hydrocarbon group having 1 to 6 carbon atoms, or a phenyl group), and is a copolymer consisting of one or more types of structural units such as R2SiC (R represents hydrogen, a hydrocarbon group having 1 to 6 carbon atoms, or a phenyl group), and is It is particularly preferred because it dissolves well.

Note that if the viscosity of the oil phase is higher than 500 cps at room temperature, stickiness will be felt during application, and the characteristics of the present invention will not be achieved.

The amount of oil blended is 95 to 95% of the total amount of cosmetics as the total amount of oil phase.
It is 40%.

The oil mentioned above has a boiling point of 260°C at normal pressure.
By using the following volatile oil components, it spreads easily and does not put a burden on the skin during application, provides a light feeling after application, and can also improve water resistance, oil resistance, and sebum resistance.

By the way, one of the requirements for a two-layer liquid make-up cosmetic is that the powder has good redispersibility.

If you leave two-layer liquid makeup cosmetics undisturbed for a long time,
The powder settles and accumulates, but when used, the powder is shaken by hand to re-disperse the accumulated powder, and the powder and oil are used in a uniform state. At this time, if the redispersibility of the powder is poor, the powder and oil will not be mixed uniformly, which will be very inconvenient.

When silicone oil and silicone resin are used together as oil components, not only further improvements in water resistance, oil resistance, and sweat resistance can be obtained, but also better redispersibility of the powder than when other oil components are used. Among the silicone resins mentioned above, in particular, a polymer consisting of a combination of 5i02 and R35io□/2 was the most excellent in terms of redispersibility.

Naturally, the makeup cosmetic according to the present invention may include surfactants, as long as they do not impair the effects of the present invention.
Flavors, antioxidants, preservatives, ultraviolet absorbers, drugs, etc. can be added.
