Description

Powdery white cosmetic composition with excellent sebum absorption ability

The present invention relates to a powdery tincture cosmetic composition having excellent sebum absorption ability, and more particularly, to a powdery tincture cosmetic composition which contains a large amount of spherical silica and has excellent sebum absorption ability, but is easy to formulate.

Powder powder is a kind of make-up cosmetics used to change the color of the face to make it look attractive or conceal defects such as blemishes and freckles. Face powder, compact and cheek paper according to the composition of powder and oil , Eye shadow and two-way cake. In powdery color cosmetics, color powders such as talc, mica, sericite, boron nitride, titanium dioxide, and various pigments are used as main ingredients for imparting coatability and colorability of cosmetics, and oil components disperse powders and make cosmetics. As a function of improving the feeling of use, silicone-based, ester-based, triglyceride-based, higher alcohol-based oils are mainly used.

Such color cosmetics are applied to the skin and adhered to the skin for about 4-8 hours, and a change in the cosmetic film is caused by sweat and sebum secreted from the skin during the application time. That is, when sebum or sweat is secreted from the face, the surface of the powder becomes wet, and thus, the reflectance is lowered, the color becomes dull, and the appearance of grease appears, resulting in deterioration of the makeup persistence. This is especially true in the summer months when the temperature is high, and during sports and leisure activities.

In order to solve the above disadvantages, by mixing a large amount of porous silica, hollow silica and the like with excellent oil absorption properties in the powder to absorb the sweat or sebum secreted first, it is possible to prevent the surface wetting phenomenon of the powders, In the case of using a large amount, sebum oil absorption ability of the product is improved, but there is a disadvantage in that the formulation is difficult because the compression moldability of the cosmetic containing silica.

In addition, as a method of formulating a cosmetic composition, a reaction of solidifying the cosmetic composition by hydrating CaSO ₄ 1 / 2H ₂ 0 is known as in the following scheme.

[Chemical formula] CaSO ₄ · 1 / 2H ₂ 0 + 3 / 2H ₂ 0 → CaSO ₄ · 2H ₂ 0

However, if the cosmetic composition is formulated using such a hydration reaction, the product can be molded similarly to the compression molding method, but not only the feeling of the product is worsened, but also the pay-off, which is a transfer performance of the product to puffs, in particular. In order to improve the performance, alcohol is added (European Patent No. 95889), mica is used (US Pat. No. 5,049,376), or glycerin is added to improve the feeling and heat treatment at a temperature of 120 ° C. to the CaSO ₄ · 1 / 2H ₂ 0, and CaSO ₄ · it has been suggested a method for adjusting the ratio of 2H ₂ 0 (U.S. Patent No. 4,724,138). However, such treatment does not improve the pay-off performance and moldability to the same level as the cosmetic composition prepared by compression molding.

Accordingly, an object of the present invention is to provide a powdery tincture composition which is excellent in compressibility of a product while containing a large amount of silica and having an improved pay-off performance.

Another object of the present invention is to provide a powdery tincture composition having no unevenness in hardness due to air pockets and excellent sebum oil absorption ability.

Still another object of the present invention is to provide a powdery color cosmetic composition which is less in color discoloration due to sebum absorption, and is capable of obtaining a natural cosmetic effect by allowing transparent and clean makeup, which is a characteristic of spherical powder.

In order to achieve the above object, the present invention provides a powder powder composition comprising 10 to 30% by weight of spherical silica and 10 to 60% by weight of CaSO ₄ .2H ₂ 0 and 20 to 75% by weight of powder. do.

Hereinafter, the present invention will be described in more detail.

The present invention is based on the fact that the sebum-absorbing ability of the spherical hollow, mesoporous or porous silica is excellent, and the contact area between each other is extremely small, so that the pay-off characteristics of the cosmetic can be improved. A powdery color cosmetic composition is prepared by simultaneously applying a hydration reaction of CaSO ₄ 1 / 2H ₂ 0. Therefore, powder powder composition of the present invention comprises 10 to 30% by weight of spherical silica and 10 to 60% by weight of CaSO ₄ .2H ₂ 0 and 20 to 75% by weight of powder. In addition, powder powder composition of the present invention may further comprise 3 to 15% by weight of oil, and may be added stabilizers, preservatives, fragrances and the like as necessary.

The spherical hollow, mesoporous or porous silica used in the color cosmetic composition of the present invention absorbs sweat or sebum secreted from the skin and improves the pay-off performance of the cosmetic composition. 10 to 30% by weight based on the weight ratio. When the amount of silica used is less than 10% by weight, not only sweat or sebum absorbing ability is lowered, but also takes longer to manufacture than a general compression molding method, and it is not suitable.

CaSO ₄ .2H ₂ 0 in the color cosmetic composition is produced by the hydration reaction of CaSO ₄ 1 / 2H ₂ 0 and serves to solidify the powdery color cosmetic composition. The amount of CaSO ₄ .1 / 2H ₂ 0 used for the solidification of the color cosmetic composition of the present invention is used within the range of 0.8 to 3.0% by weight relative to the silica, or more preferably 8 to 50% by weight relative to the total cosmetic composition It is good to use within. As such, when CaSO ₄ 1 / 2H ₂ 0 is used, 10 to 60% by weight of CaSO ₄ · 2H ₂ 0 is present in the final product. If the amount is less than 0.8 weight ratio of silica, the solidification reaction is not sufficiently achieved. If the weight ratio exceeds 3.0, not only the pay-off property is lowered but also the content of powder is so small that the color tone and the feeling of use become worse.

As the powder used in the present invention, known pigments (iron oxide, chromium oxide, chlorophyll, etc.), white pigments (titanium dioxide, zincated, etc.), sieving pigments (talc, kaolin, mica, sericite, calcium carbonate, barium sulfate, etc.) ), Pearl pigments (bismuth oxychloride, mica titanium) and the like can all be used, these serve to control the coating and coloring properties of the cosmetic composition, the refractive index of the light is changed depending on the particle size, the skin hiding power is different.

As the oil to be added, one or two or more kinds of oils used in cosmetics, such as silicone, ester, triglyceride, and higher alcohol, may be used, and may be used by emulsifying in an aqueous phase. An emulsifier for emulsifying the oil may be appropriately selected depending on the type of oil. The oil as a function to complement the dry and rough feeling of CaSO ₄ · 2H ₂ 0 and to improve the adhesion of the product, it is possible to prepare the color cosmetic of the present invention in the form of a solid powder without adding oil, but the skin It is preferable to use 3 to 15% by weight of the total powder color cosmetic composition in order to make it appear smooth or to increase the coloring power of the color cosmetic. If the content of the oil is less than 3% by weight does not improve the feeling of use, if it exceeds 15% by weight, the adhesion is increased but the sebum oil absorption ability of the product is lowered.

In order to prepare the powder powder composition of the present invention, 20 to 75% by weight of one or more powders, 10 to 30% by weight of spherical silica, and CaSO ₄ 1 / 2H ₂ 0 8 to 50% by weight are mixed and ground. Next, it adds and mixes in the water phase part to which preservative, fragrance, etc. were added. At this time, some of the purified water included in the water phase is hydrated with CaSO ₄ · 1 / 2H ₂ 0 to become CaSO ₄ · 2H ₂ 0 and included in the final product, and the remaining purified water is added to give fluidity to the product during the manufacturing process. As a result, it is dried and removed in a subsequent process. Therefore, the amount of purified water to be used should be appropriately determined according to the amount of CaSO ₄ · 1 / 2H ₂ 0 included in the powder part, the content of silica and the water absorption characteristics, and impart fluidity by adding alcohol, such as volatile solvent, in addition to purified water. You may. The greater the amount of purified water added, the better the fluidity is, but when it is added, there is a disadvantage that the stability of the product is lowered. Therefore, an appropriate amount should be selected and added. 3-15 parts by weight of oil, such as silicone oil, may be added to the water phase as needed. After mixing and stirring the powder portion, the air bubbles are defoamed, poured into a container, and then poured into a container at about 60 ° C. It can be dried to prepare the color cosmetic composition of the present invention.

As in the manufacture of the two-way cake, when the powder is siliconized to enhance the water resistance of the powder, the powder is mixed and stirred in an aqueous phase containing 1 to 10% by weight of reactive silicone having a Si-H group, dried and then Heat to 105-130 ° C. At this time, when the amount of the reactive silicone is less than 1% by weight, the water resistance of the powder does not appear, and even if the amount exceeds 10% by weight, the water resistance of the powder no longer increases. In this way, the OH and Si-H groups on the surface of the powder react to form a silicone oil on the surface of the powder to enhance the water resistance of the powder. If the silicon-coated powder is mixed in advance with the aqueous phase, the aqueous phase and the water-resistant powder are not completely mixed with each other, so there is a problem that the hardness is uneven and the stability of the product is inferior.

As can be seen from Table 2 and Table 4, the sebum absorption capacity (about 80-160%) of Example 1 to Example 6 using CaSO ₄ 1 / 2H ₂ 0 simultaneously with spherical silica was generally compression molding. It is not only superior to sebum absorption capacity (50-80%) of the product by the method, but also excellent in dropping stability, and compared to using only CaSO ₄ · 1 / 2H ₂ 0 (Comparative Example 1). This is excellent. In addition, when 1% of CaSO ₄ 1 / 2H ₂ 0 was used (Comparative Example 4), it did not contribute significantly to the stability of the product.

Therefore, it can be seen that the use of spheroidal silica, mesoporous silica and CaSO ₄ 1 / 2H ₂ 0 10-45% by weight is excellent in the pay-off characteristics, and the product stability and sebum absorption characteristics are excellent. In addition, Example 6 using the reactive silicone was excellent in water resistance and excellent overall physical properties.

Therefore, the color cosmetic composition of the present invention has a similar pay-off performance and no air pocket is formed, compared to the cosmetics prepared by the conventional compression molding method, there is no hardness non-uniformity and excellent moldability. In addition, the sebum absorption capacity of the cosmetics of the present invention is about 1.5-3 times higher than the sebum absorption capacity of the cosmetics prepared by the general compression molding method, and there is little color discoloration due to sebum absorption, and the characteristic of the globular powder is transparent. It is possible to make clean and natural make-up effect.
