Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improved make-up cosmetics, which expand the range of usability of the make-up cosmetics, impart a moisturizing effect to the skin, and improve the uniformity of the makeup. The purpose of the present invention is to provide a new make-up cosmetic that has improved sustainability, as well as improved dispersion and filling properties in oil-gel products and prevention of caking in powder products.

In recent years, consumer preferences regarding cosmetics have become more diversified, and when considering makeup cosmetics, it has become a requirement to provide products that are compatible with skin characteristics. For example, people with normal or dry skin may feel uncomfortable when using cosmetics.
There is a strong demand for a moisturizing feel in the makeup finish, and for this reason, powder products and oil gel products have been formulated with oils in a lynch-based formulation to impart a moisturizing feel to the skin. However, the emollient effect of oil alone has its limits, and recently many women have complained of a kind of dry feeling, and the reality is that it does not necessarily meet the demands of consumer demand.

On the other hand, for people with oily skin that secretes a lot of sebum, the makeup film becomes absorbed by the sebum after about 15 to 30 minutes when using cosmetic products or oil gel products that contain only regular oils, becoming transparent and then disappearing. There are many cases where cosmetics end up being damaged, and there are significant drawbacks in terms of the durability of the cosmetic effect. Therefore, in order to make oil gel products last longer and prevent a greasy makeup film caused by oil, we have taken measures to prevent makeup from forming a sticky makeup film due to oil content. The cosmetic film is often broken down relatively easily.The way the cosmetic film breaks down is as follows:
Powder particles may accumulate in the pores and skin grooves peculiar to oil gel products, break down in spots, or be deposited in anonymous lines, etc.
Furthermore, skin moisturizing ingredients (water-soluble ingredients, etc.) should be added to oil-glu products and powder products in order to improve the above-mentioned drawbacks, such as K staining around the lips and even inhibiting the effectiveness of the lipstick. However, if a skin moisturizing ingredient is simply added to a formulation, for example, in oil gel products, the skin moisturizing ingredient and oil may separate due to poor affinity, or pigments may aggregate and their dispersibility may be affected. This may cause pigment floating or flow marks during filling, or the viscosity of the formulation may increase significantly, making filling and molding difficult, causing the filled contents to have an uneven appearance or cracking. It was also a cause of quality deterioration, such as the presence of dirt. On the other hand, in the case of powder coated with oil, the brightness was significantly reduced, the hue was shifted, and there was a large discrepancy between the applied color and the external color, impairing the original makeup effect.

Therefore, as a result of intensive research to overcome these drawbacks, the present inventor found that it is suitable for makeup cosmetics containing compression-disintegrating soft spherical resin capsules containing skin moisturizing ingredients. The present invention has been completed.

The present invention is a make-up cosmetic characterized by containing one or more types of compression-disintegrable soft spherical resin capsules containing skin moisturizing ingredients.

The term "compression-disintegrable soft spherical resin capsule" as used herein refers to a resin capsule that is constructed so that the resin film of the capsule is broken by pressure from a finger or the like during makeup application, and the skin moisturizing ingredients contained therein are released.

The compression-disintegrable soft spherical resin capsules used in the present invention preferably have a particle size of about 1 to 40 μm. When the capsule particle size is as small as 1 μm, when used as a makeup cosmetic, it has a soft spherical shape and has the expected tactile effects on the skin (smoothness, softness, ease of spreading).
If the thickness exceeds 40 μm, it will give a rough and strange feeling. Considering the particle size distribution during the production of resin capsules, the average particle size that satisfies the particle size range of 1 to 40 μm is approximately 2 to 20 μm. In addition, the spherical shape of the capsule naturally includes not only a true spherical shape but also a circular shape and other similar spherical shapes.

Furthermore, the amount of compression-disintegrable soft spherical resin capsules containing skin moisturizing ingredients in makeup cosmetics varies depending on the intended product type, but is 0.1 to 90%.
It can be said that weight base/to is a suitable range.

In addition, the pressure resistance (destruction) strength of the compression-disintegrable soft spherical resin capsule in the encapsulated state is approximately 2 to 40 kg/CIA,
Preferably 2~30kl? /-. If the pressure resistance is lower than 2 kg/-, when used in makeup cosmetics,
It is inappropriate because it is easily destroyed by external pressure or impact force during the equipment process.

If the pressure resistance exceeds 1c40kg/c++1, the capsule will not break during the makeup operation, which is undesirable.

The amount of components contained in the compression-disintegrable soft spherical resin capsule is 10 to 90 weight percent, preferably 50 to 90 weight percent, based on the entire capsule. If the amount of capsules contained is less than 10% by weight, the amount of capsules added to the makeup cosmetics will be greatly increased, making it difficult to produce an effect, and considering the economic cost.
It is disadvantageous. Also, if the weight exceeds 90%, the cuff
The remaining cell shell is significantly reduced, and the membrane cannot be put to practical use due to its pressure resistance.

When the material applied to the compression-disintegrable soft spherical resin capsule of the present invention contains skin moisturizing ingredients, the capsule membrane has sufficient impermeability to these inclusions in order to maintain their preservation. Select and use. Since it is necessary to add it to cosmetics, it is preferable that the capsule membrane does not contain monomers that may have harmful effects. .

The compression-disintegrating resin capsule of the present invention is preferably amorphous and transparent (light transmitting),
For example, acrylic acid, methacrylic acid, acrylic esters (methyl ester, ethyl ester, etc.), methacrylic esters (methyl ester, ethyl ester, etc.), vinyl acetate, vinyl chloride, vinyl chloride/, ethylene, styrene/, divinylbenzene, ethylene A homopolymer or copolymer selected from one or more types of glycol dimethacrylate and the like satisfies the above conditions. However, the materials are not necessarily limited to these materials as long as they satisfy the above conditions.

Next, the skin moisturizing ingredients contained in the compression-disintegrable soft spherical resin capsules include water, alcohols such as ethanol and inbanol, ethylene glycol, probilene/glycol, 1,3-phthylenoglycol, polyethylene glycol, and glycerin/glycol. , polyhydric alcohols such as polyglycerin, glucose, galactose, fructose,
Sugars or sugar alcohols such as maltose, lactose, sucrose, nrubitol, mannitol, xylitol, sugar derivatives such as polyoxyethylene methyl glucoside, polyoxypropylene methyl glucoside, dextrin, hyaluronic acid, co/droitic acid/sulfuric acid, heparin, etc. Polysaccharides, amino acids and related substances such as glycerol, aranino, glutamic acid, serine, arginine, PCA soda, polypeptides such as collagen, organic acid salts such as sodium citrate, sodium lactate, and sodium malate, vitamin 1311 Examples include water-soluble vitamins or vitamin-like substances such as B6 r C, nicotinic acid, and acid, as well as inosit, phytic acid, and extracts of various herbal medicines, but in any case, water, alcohol Alternatively, any raw material applicable to cosmetics that can exert some kind of skin moisturizing effect (moisturizing effect) when layered with polyhydric alcohol or the like may be used, but is not limited to these.

The method itself for producing compression-disintegrable soft spherical resin capsules in the present invention involves dissolving a homopolymer or a copolymer of a material such as methacrylic acid ester described above in an appropriate organic solvent, and adding it to an oil phase (0). Then, the various skin moisturizing ingredients (W) described above are emulsified and dispersed to form a W10 emulsion, and an organic solvent that serves as a non-solvent for the polymer or another polymer that causes precipitation of the polymer is added thereto. Then, the polymer is precipitated into a film around the skin moisturizing ingredient (phase separation method), or the above W1
W1 by dispersing the type 0 emulsion in an aqueous phase containing an emulsifier.
0/W type multiple emulsion/ is formed, further heated and/
Alternatively, there is a method (in-liquid drying method) in which the organic solvent in the oil phase is removed under reduced pressure to form a polymer film around the skin moisturizing ingredient.

The desired particle size, encapsulation amount, and pressure resistance strength can be adjusted by selecting the type of capsule material, the ratio of the capsule material to the encapsulation component, dispersion conditions, or the amount and type of emulsifier.

Hereinafter, the manufacturing method will be explained in more detail with reference to specific examples.

This product has an average particle size of about 10 μm and an encapsulated amount of hyaluronic acid aqueous solution Vi7.
At 3.1%, the compressive strength was 9 to 12 Yu/cd.

The characteristics of the compressible disintegrating soft spherical resin capsule applied to the present invention will be described in detail below.First of all, within the same dosage form, the feeling of use (feel) varies greatly, and the width can be varied arbitrarily. It can be changed to

For example, in a smooth and fluid powder product,
For products containing soft spherical resin capsules that disintegrate under compression, when the capsules are destroyed, the skin moisturizing ingredients contained within them are exposed, and the powder is coated to prevent the interaction between the oil and the skin moisturizing ingredients. Okay, my skin is more firm and I'm at 9.
It retains moisture in the skin and prevents the feeling of dryness during make-up.Also, in the case of make-up cosmetics that are coated with only regular oils, the thickness of the applied make-up layer may be uneven, causing the powder to appear floating. In most cases, the feeling of adhesion disappears over time.

This is originally caused by weak adhesion and adhesion to the skin, which manifests itself in poor makeup longevity. When the compression-disintegrating soft spherical resin capsule of the present invention is used, a portion of the skin moisturizing ingredient forms a layer on the powder particles that adhere to the skin with a non-uniform thickness, covering the skin of the powder particles. In addition to improving adhesion to cosmetic tools (puffs), it also helps to even out excess powder particles that are unevenly attached to the desk surface or remove excess powder particles that adhere to cosmetic tools (puffs). It greatly contributes to improving the longevity of makeup.

Furthermore, when purified water or ethanol is used as the encapsulating substance, in addition to the rough feel, the capsules are destroyed, giving the parallax a refreshing feeling.

In addition, when the compression-disintegrable soft spherical resin capsule of the present invention is applied to emulsifying foundation: I/, since the substance encapsulated in the capsule does not directly affect emulsification, it has no effect on viscosity, stability, or use. It is possible to mix substances according to the purpose, regardless of gender, and there is no need to consider the feel and usability of conventional emulsified type 7 andesio/, and the range of touch can be expanded.

Second, the compression-disintegrable soft spherical resin cuff cell does not feel like a foreign body to the touch after use, and does not visually remain on the skin at all. The reason for this is that the capsule is spherical and has a lot of elasticity, and has the property of being destroyed by external force when used on a desk. The microparticles of the destroyed shell become thin plate-shaped and adhere to the skin, and the capsule itself has high transparency (light transmittance) and has an affinity for oil. This is because it does not give any impression of residue.

Thirdly, the amount of skin moisturizing ingredients in the powder product is
Even if you use a substantially larger amount than the amount normally available on the market, it will not apply to the puff or be uniform on the skin, or cause the powder to cook.
Quality can be maintained and improved. Commercially available powder products coat the powder surface with oil, etc., but due to the increase in the amount of oil, the weight of the coated powder itself, and the adhesion force of the coated oil, a caking phenomenon may occur, causing the puff to dry out. If the powder adheres to the skin, it will be hard to spread when applied to the skin, and it will be difficult to spread it evenly, and the applied film will adhere unevenly to the skin, resulting in a drastic reduction in the makeup effect. Powder products containing compression-disintegrable soft spherical resin capsules contain various substances such as moisturizers within the capsules, so they have low adhesion, high fluidity, light powder, and easy spread, making them easy to use on desk surfaces. The coating film is uniform and the makeup effect is enhanced.

On the other hand, in powder products with a reduced amount of oil, the exposed skin moisturizing ingredients become compatible with the skin due to the destruction of the capsule, and the wetness of the powder also plays a role, making it difficult for the powder to adhere to the skin. It improves the wearability, durability of makeup, and adhesion, and eliminates the factors that reduce the effectiveness of makeup, such as white cast and fluff.

Fourth, in aqueous, non-aqueous, dispersed, emulsified, and other cosmetics, skin moisturizing ingredients may cause deterioration, decomposition, or deterioration due to interaction with the surface activity of the system or powder. Therefore, by encapsulating the skin moisturizing ingredients, it is possible to cut off their interaction with the skin moisturizing ingredients and stabilize the skin moisturizing ingredients.

Fifth, it is important to encapsulate skin moisturizing ingredients to prevent thickening of cosmetic systems due to interactions with other ingredients, and to prevent oils, powders, and skin moisturizing ingredients from encapsulating when the capsules are broken. This interaction strengthens the cosmetic film, improves its affinity and adhesion to the skin, and provides makeup cosmetics with long-lasting cosmetic effects regardless of skin properties.

Next, in order to demonstrate that the make-up cosmetics containing the compression-disintegrable soft spherical resin capsules according to the present invention have an excellent feeling of use and are effective for people with a wide range of skin characteristics, Examples will be described below. A long-term comparative test was conducted on 100 women using the makeup cosmetics of the present invention (1) to (3) and commercially available makeup cosmetics. The results are shown in Table-1. Furthermore, regarding Pau F-7A/Desho/ (Example 2 and comparative product), in order to examine the difference in effectiveness depending on the skin type characteristics, the above 100 women were classified into skin types (28 women with oily skin type). , normal 28 people, dry 44 people
