Functional Cosmetic Compound of Powder Properties {Functional Cosmetic Compound of Powder type}

The present invention relates to a functional cosmetic composition of powder form, and more particularly, by properly blending a cosmetic active ingredient and a functional ingredient, stabilizes a functional ingredient that is likely to be destroyed by oxidation by heat, light, moisture, and air, and in a good state. The present invention relates to a functional cosmetic composition of a powder property in which the functional ingredients of each functional ingredient are maximized by dissolving them in a liquid state without being destroyed even when rubbed by hand, ie, rubbing by hand. .

Cosmetics are widely used to seek external beauty through the appearance of fragrance or color while improving and maintaining the condition of the skin by applying it to the delicate and sensitive skin.

Since the beginning of human use of these cosmetics, the use of functional ingredients along with the desire of consumers seeking wrinkle improvement, skin elasticity, whitening, and defect concealment has been a major research task for developers studying cosmetics. Theories about the efficacy and effects of placenta, arbutin, lecithin, licorice, vitamin-C, retinol, etc. are well known in the general journal.

Conventional techniques for containing the functional ingredients in cosmetics include a separate functional ingredient and a lotion, each method is used to mix and use each other, and another technique is a method of containing the functional ingredient in the emulsion and lotion. However, these methods suffer from a lack of skincare concept as a powder formulation with defect concealment. In addition, it is difficult to use due to the complicated process and high compounding of functional components, and there is a problem that the stability is not good, such as being oxidized and destroyed by heat, light, moisture, air, etc., when formulated high in the formulation.

Accordingly, the present invention, by properly blending a cosmetic active ingredient and a functional ingredient, stabilizes the functional ingredient that is easily destroyed by oxidation by heat, light, moisture, air, and the like, and maintains the powder in a good state, that is, by hand. The purpose of the present invention is to provide a functional cosmetic composition and a manufacturing method of a powder property in which the functional ingredients are dissolved in a liquid state without ruining, maximizing the function of each functional ingredient and introducing a skin care concept even when rubbed.

The present invention is a cosmetic composition of the powder property containing a cosmetic active ingredient,

1 to 15% by weight of silica silates in the total composition; 0.01 to 20% by weight of an oxide selected from iron oxide, titanium oxide and mixtures thereof; Solvent 50 to 90% by weight; And a powdery cosmetic composition containing 1 to 15% by weight of the functional component, and containing 3 to 15 parts by weight of the solvent with respect to 1 part by weight of the mixture of the silica sillate and the oxide.

Referring to the present invention in more detail as follows.

The present invention stabilizes functional ingredients that are susceptible to destruction by oxidation by heat, light, moisture, and air by appropriately blending a cosmetic active ingredient and a functional ingredient. It relates to a functional cosmetic composition.

First, as the cosmetic active ingredient used in the present invention, 1 to 15% by weight of silica silicate having a specific surface area of hydrophobization rate of 100 m ² / g or more in the total composition is used. If it is less than 100 m ² / g, it becomes impossible to sufficiently powder the water phase component used, and when silica having a low hydrophobicity ratio is used, the affinity with the water phase component becomes high and there is a problem that it is impossible to powder it stably. In addition, when the amount of use is less than 1% by weight it is impossible to fully powder the water phase component, on the other hand, when added in excess of 15% by weight it is impossible to fully liquefy during the application and the problem remains cloudy after use This is undesirable. Here, the silica silates used may be commercially available hydrophobized Cabosi1 TS-530 (manufactured by Cabot), Erosil K-12, Erosil R-972, etc. as particulate silica having a specific surface area of 100 m ² / g. have.

In addition, the use of the pigment as a cosmetic active ingredient used in the present invention, which has a UV protection and cover power, such a pigment is properly mixed with an oxide selected from titanium oxide, mica, iron oxide and mixtures thereof currently commercially available The content can be used as 0.01 to 20% by weight. If the amount of use is less than 0.0l% by weight, it is not preferable to give a stiff texture when used. On the other hand, when the amount is used in excess of 20% by weight, it has a heavy feeling at the same time as giving a sticky texture when used.

In addition, in the present invention, the solvent used to obtain the moisturizing component is glycerin, diglycerin, triglycerine, propylene glycol, 1,3-butylene glycol, hexylene glycol, sorbitol, panthenol, trehalose, which are currently commercialized with water. , Sodium-hyaluronate selected from the group consisting of one or two or more thereof. Here, the content is used as a solvent 50 to 90% by weight, if less than 50% by weight is difficult to liquefy the problem, while when used in excess of 90% by weight is difficult to form a stable powder There is a problem.

In addition, the present invention can obtain the optimum feeling when the solvent is contained in 3 to 15 parts by weight with respect to 1 part by weight of the mixture of the oxide.

As the functional ingredient used in the present invention, one or two or more selected from placenta, arbutin, lecithin, licorice, vitamin-C, retinol may be appropriately used.

Using the cosmetic active ingredient described above in detail the manufacturing process of the functional cosmetic composition of the powder property as follows.

First, an oxide mixture in which silica silicate, iron oxide, titanium oxide, and a mixture thereof is appropriately mixed is uniformly mixed by using a mixer, and the solvent is slowly added while stirring, and then the functional component is added again. By stirring, the functional cosmetic composition of the powder property can be obtained.

Figure 1 is a micrograph of the powdery cosmetics formed according to the present invention, including the micro powder, iron oxide, titanium dioxide and functional ingredients. FIG. 2 is a micrograph showing an enlarged view of the functional component part B. FIG. 3 is a micrograph showing light transparent from the bottom of the functional component part B. FIG. 4 shows only a dotted line in FIG. 3. Photomicrograph taken.

Hereinafter, the present invention will be described in more detail with reference to Examples, but the present invention is not limited by Examples.

Comparative Examples 1 to 7 and Example 1

Next to the composition and content shown in Table 1 was used to prepare a cosmetic using a conventional method for preparing a cosmetic. In addition, for each powdered, defects were determined by the following method and criteria for closing force, degree of visual acuity, impact strength and liquefaction, and the results are shown in Table 1 below.

Measurement method and criterion

(A) Powdering: It carried out through 50 (300 micrometers).

○: pass over 95%

△: pass more than 70%

×: 50% or more pass

(B) Degree of visual acuity: A method of checking after 7 days at 40 ° C. was used.

○: No change in appearance

△: slight color change

×: Separation phenomenon (Aqueous layer is at the bottom)

(C) Impact strength: 20 g of a 40 ml sample bottle was charged and measured by dropping it from a height of 50 cm.

○: No change in appearance

△: slight separation

×: separation phenomenon (water layer is at the bottom)

(D) Liquefaction: Measured using a method of rubbing hands by taking 1g of the contents.

○: quickly liquefied

△: liquefied slowly

×: liquefaction is slow and white

(E) Covering up defects (covering power)

○: Good

△: normal

×: bad

According to the above, Comparative Example 1 was impossible to powder stably and difficult to make powder properties. Comparative Example 2 almost satisfies the test item with the most suitable compounding ratio, and the stability over time is poor. In Comparative Example 3, the powder is not uniformly formed, the liquefaction is not easy, and the cloudiness remains after use. In Comparative Example 4, the powder is uniformly formed in comparison with Comparative Example 3, but the liquidity is not easy and the feeling of use is heavy. In addition, uniform powdering is not possible, liquefaction is not easy, and cloudiness is left in use. Comparative Example 6 is the most suitable formulation as in Comparative Example 2, but also good aging stability is heavy. In addition, Comparative Example 7 is not easily powdered when a large amount of 1,3-butylene glycol is blended. In addition, Example 1 is a foundation of a powder property with a coverage of the skin care concept that stabilized the functional ingredient is satisfied, almost satisfying the test item, but there is a feeling of slightly powdery in use.

As described above, when the present invention is used while maintaining the powder in a good state by stabilizing a functional component that is susceptible to destruction by oxidation by heat, light, moisture, and air, by appropriately blending a cosmetic active ingredient and a functional ingredient, In other words, even when rubbing by hand, the functional ingredients are not destroyed and are dissolved in the liquid to maximize the function of each functional ingredient and the skin care concept is introduced, and the high compounding of the functional ingredients gives quick effects such as wrinkle improvement, skin elasticity and whitening effect. It can be seen that, in the past, powder and lotion are separately used, so there is no problem that the use of the mixture is less troublesome when used, and it can be used as a liquid foundation with concealment defects while using it as a powdery product. .
