Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a W10 type emulsified foundation composition which is stored (filled) 17 in the inner tray of a compact and used while maintaining its shape.

In more detail, it spreads lightly when applied to the skin, has good adhesion (no twisting or movement), gives a very moist feel without stickiness, and is compact (with gold 111).
There are W10-type emulsified foundation compositions that can be easily poured (contained) onto surfaces (i.e. or resin surfaces) and are in compact form. (advantages and disadvantages). It's too late,
Emulsified type (ay/- = Ruiwa W/^ foundation) has a very light texture and gives a moist and dewy finish, giving it an excellent makeup effect, but the container shape is However, it has the disadvantage that it is limited to tubes and bottles and is inferior in functionality (ease of use).

In addition, the powder (cake) type fancijohn has a mold size of 1 and is stored in a compact, so it is very easy to use and has a lot of functionality, but on the other hand, it has a poor feel. It has the disadvantage of being dry (powdery). Oil-based foundations are convenient and highly functional because they are poured into a package and stored compactly, but on the other hand, they have the disadvantage of being oily and sticky. There is. Therefore, you are so talented! The advantages of these types,
As is clear from the summary of the disadvantages, emulsified foundations that can be compacted (combined, poured into a resin surface, etc.) are highly functional, have a very light feel, and are easy to use all the time. Expectations are high for logical cosmetics that provide a fresh and beautiful makeup effect.

However, when pouring 0//W type or W10 type emulsified foundation into a medium plate (combined volume, resin surface, etc.), water evaporates immediately with O/W type emulsified foundation and over time with W/D type emulsified foundation. This causes abnormalities in appearance. Specifically, oil bleeding due to the collapse of the emulsion, peeling from the periphery of the bundle due to shrinkage of the contents (foundation composition), depression of the surface, and cracks.
Even if I won first prize, I would not be satisfied. Conventional known documents (JP-A-58-86045, JP-A-58-12784)

, Japanese Patent Publication No. 57-27785, and Japanese Patent Publication No. 58-105
906) discloses W2O type emulsions, but when these W10 type emulsions are poured into the inner tray (combined volume or resin surface) of a compact and made into a product,
There is an obvious problem. For example, JP-A FiB5 B-86
In the case of 045, the surface morphology was unstable (the surface did not harden and leaked easily at high temperatures), and abnormalities in appearance such as oil staining were observed. JP-A-58-127841 and JP-A-T18
When the W-shaped emulsion of 56-58608 is poured into a product, it is oily because the pigment content is small compared to the total weight. ) Peeling from the periphery was also observed,
It has been found to be inadequate for this purpose. Also, Special Publication No. 56-12608 and Special Publication No. 57-2778
In the case of the W10 type emulsion described in No. 5, the emulsion may be destroyed due to the low emulsifying power of the emulsifier to be blended or because the water content is too high, resulting in cracks, oil bleeding, and shrinkage of the W10 type emulsion 5- composition. occur. Also, JP-A-58-105
When the W10 type emulsion of 906 is poured into a medium plate and made into a product, the water evaporates over about half a year and the W10
Assimilation of the mold emulsion and partial depression occur, which is insufficient.

As a result of intensive research aimed at improving the drawbacks of the conventional technology, the present inventors have found that a water-in-oil type (WO type) emulsified foundation composition with the configuration described below gives a very light feel and has a beautiful makeup effect. Not only that, but if the compact is made into a compact by pouring (accommodating) it into the inner tray (combined volumes, resin surface, etc.), it may cause the above-mentioned appearance abnormalities, such as oil stains, peeling from the edges, caving, and cracks. f'l. The present invention has been completed based on the discovery that this does not occur at all.

The purpose of the present invention is to have a compact form that is high in functionality and excellent in functionality, and that when applied to the skin, it spreads lightly.
Moreover, it is an object of the present invention to provide a water-in-oil type (W2O type) emulsified foundation composition that has good adhesion (no wrinkling or movement), is sticky, and can give a very moist and good feel.

6- Also contains a pigment, and the pigment contains 5 to 25% by weight of at least one of talc, kaolin, mica, and mica titanium having an ion exchange capacity of 80 milligram equivalents/1007 or more. , titanium dioxide, iron oxide, yellow iron oxide, and black iron oxide, and the total content of the pigment is 30% to 30% baric acid.

The pigment used in the present invention includes titanium dioxide, red iron oxide, yellow iron oxide, and black iron oxide as essential components, and talc, kaolin, and mica with a cation exchange capacity of 80 milligram equivalents of 71007 or less, which is the base titanium. At least one is blended in a range of 5 to 25% blood volume. And this
The total amount of pigments of L et al. is 80 to 6% by weight of the composition.
0% by weight, preferably 85-55% by weight. Generally, there is no example of a water-in-oil type (Wlo type) emulsion containing a pigment at such a high concentration. If a material with a cation exchange capacity higher than 80 milligram equivalents/100F is used, it may impair the stability of the emulsion, causing aggregation of l, N, pigments, oozing of oil, and discoloration of the medium. When pouring into a sink, it promotes moisture evaporation and prevents shrinkage, peeling, sinking, cracking, etc. of the foundation composition.

Incidentally, the term cation exchange agent used here refers to the ability to perform positive ion exchange as one's own.

That is, fill the bottom of a column chromatography column (diameter 1.0 to 1.2 m, length ao cnr) with absorbent cotton, and pour filter paper milk into the bottom of the column to form a filtration layer with a fv size of 5 cm. 0. Fill with a mixture of about 12 fM and quartz sand.

Transfer this column chromatography tube to IN-ammonium acetate solution 10
Penetration takes 4 to 20 hours at 0-. Next, the sample is washed with 80% ethyl alcohol 50% to remove excess ammonium acetate, and then washed with 100 rnt of a 10% saline solution to exchange and leaching ammonium ions. Transfer the leachate obtained in the receiver to a 2 (lo1 n1!) volumetric flask, add water to make it exactly 200, and measure the ammonium carbon content at a certain point. Transfer a certain amount to a 50 - Nessler tube. , Rossel's salt 2-, and Nenurah test 1- are added to the solution, and the volume is made up to 50-, with water, and compared with the ammonia standard solution.

The nonpolar oily substance used in the present invention is an oily substance that does not have a polar group, and preferred examples include liquid hydrocarbons, vaseline, microcrystalline wax, paraffin wax, and ceresin wax. However, it is not limited to these.

These non-polar oily substances may be used alone or in a suitable combination of two or more, and their content is 20 to 70% by weight, preferably 80 to 50% by weight based on the weight of the composition. It is. When it is less than 20% by weight, a stable emulsion composition (Wl
If O-type) is not given and the amount is more than 70% by weight, the lightening effect is likely to decrease.

In addition, ester oil, triglyceride-like oil II & cheek,
When polar oily substances such as waxes are blended, the stability of the emulsified Q-product decreases significantly, resulting in peeling of the Wlo f4'4 emulsion from the inner plate, partial collapse, cracking11, and oil leakage. etc. occur.

The solhitan oleate ester 2 used in the present invention includes solhitan monooleate, dioleate, sesquioleate, and especially monooleate 1-
(monoester) and sesquioleate (sesquiester) are preferred. They can be used alone or in combination, and their content ranges from 01 to I
O mass%, preferably (Ba is 1 to 5 mass%. (Slightly less emulsion stability than 1.1 mass%) L, 111 mass%

The content is 2 to 25 stones, %, based on the amount of the composition.
Preferably it is 8 to 15% by weight. When it is less than double shrinkage%, emulsion stability, water retention, adhesion when applied to the skin,
When the moist feeling decreases and the amount exceeds 525, the eaves and edges decrease and a sticky feeling occurs.

Water is usually added as an aqueous solution of maltitol, and the amount of water used is appropriate for the makeup. The amount is 2 to 40% by weight, preferably 5 to 20% by weight, based on the weight of the + mold. If the amount is less than 2% by weight, the light touch, moist feeling, and lightness will decrease when applied to the skin, and when poured into a medium plate, the above-mentioned appearance abnormalities, especially the W10 type emulsion, will shrink and peel, and the surface will become depressed. , remove cracks, etc.

The 1111 water bottle type (W2C type) emulsified funtion composition of the present invention can be prepared by a method of extraction. and in mixtures with pigments,
Carefully add and mix the maltitol aqueous solution while stirring. In this case, multi!・A water-bathable effect agent (active ingredient) may be dissolved in an aqueous solution [7] and mixed.

The liquid temperature during stirring and mixing is not particularly limited, but may be 60°C.
-90°C is preferred, most preferably 70-85°C. If the temperature during mixing is too low, uniformly dispersed waxes, etc. will precipitate, coarse oil particles will be likely to be partially liberated, and pigment dispersion will be poor.Also, if the temperature is too high, the components will decompose. , suppression, and deterioration may occur easily.

After mixing and emulsifying and dispersing [2], pour the mixture into a compact medium dish (meter, resin nll&>) using a suitable filling machine, level the surface, and cool to room temperature.

The W10 type emulsified funtision l114 composition of the present invention is.

It forms a uniformly stable emulsified thread in the form of water-in-oil droplets, and is compact and medium-thin (Flea L, Tree 11th Book Temple). t+
Even after setting it in the compact, JI always loses its good emulsification stability and retains moisture, and even if it is overloaded, which causes water evaporation over time, Moreover, during use, it is possible to use the conventional tube type or hole type O/W!h or W1.
Compared to the Type 0 emulsified composition, it has excellent functionality such as being more convenient to hold and can be applied (make-up) with a simple one-touch operation. The W10 type emulsion foundation composition has extremely high commercial value as it exhibits unique characteristics such as light spreading, non-stickiness, moisturization, and good adhesion to the skin. The mechanism of action is that when pigments are blended at a very high concentration to create a fairly stable W10 emulsion composition, the pigments are titanium dioxide, red iron oxide, yellow iron oxide, and black oxide.
