The present invention relates to a makeup cosmetic composition that enables the expression of matte, natural skin and has excellent spreadability, spreadability, and skin adhesion.

Description

Makeup cosmetic composition {Makeup cosmetic composition}

The present invention relates to makeup cosmetic compositions.

Cream-type cosmetic compositions have the advantage of excellent color expression and no flaking, but they have the disadvantage of breaking down the makeup film due to the shiny and thick feeling of use due to heavy oil and wax ingredients.

Compressed powder cosmetic compositions contain a large amount of spherical powder for a smooth feel. If the amount is increased, the oil used as a binder is strongly absorbed, reducing the ability to sufficiently bind the entire complex pigment, that is, the bonding strength between powders. Not only does it make compression molding difficult, but it also has the disadvantage of reducing the oiliness when used in large quantities, causing powder to fly out during makeup, reducing skin adhesion, and causing skin dryness, which reduces quality.

In order to solve the problems of conventional cosmetic compositions, various semi-solid cosmetic compositions containing a large amount of oil are being developed. Semi-solid cosmetic compositions, which mainly consist of an oil phase containing hydrocarbon oil, silicone gel, low-viscosity silicone oil, and ester oil, are being developed with advantages in terms of cosmetic makeup, such as a soft and light feel, excellent spreadability, and moisturizing feeling. The improvement of the creamy and shiny phenomenon upon application is still insufficient, and also has the disadvantage of forming an oil film around the container due to oil leakage due to the low interfacial tension and low compatibility of silicone oils. In addition, the molding stability is unstable, and the content tends to tilt during product filling or due to external shock, which has the disadvantage of lowering the quality of the product.

Semi-solid cosmetic compositions using conventional silicone gels used mica, which has excellent spreadability, as the main extender pigment to ensure applicability. However, the mica has a very large particle size, and due to its high aspect ratio, it has a very strong shine or pearly feeling, so it is not suitable for makeup to express natural skin.

Accordingly, attempts have been made to produce a semi-solid cosmetic composition by replacing the mica with talc, but there is a problem in that the floating and spreadability of the formulation is reduced, making it difficult to use.

Therefore, there is a need for research into makeup cosmetic compositions that can express matte skin without being excessively shiny.

The purpose of the present invention is to provide a makeup cosmetic composition that is non-greasy, allows for matte skin expression, and has excellent spreadability, spreadability, and skin adhesion.

In order to achieve the above purpose,

The present invention provides a makeup cosmetic composition comprising talc with an average particle size of 15 to 40 μm and polymethylsilsesquioxane with an average particle size of 3 to 5 μm.

The makeup cosmetic composition of the present invention has the effect of enabling a non-greasy, matte skin expression, and has excellent spreadability, spreadability, and skin adhesion.

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

The conventional semi-solid makeup cosmetic composition is a formulation that agglomerates powder using a silicone-based gel, and mica, which has excellent spreadability, is used as the main extender pigment to ensure the applicability of the cosmetic composition.

However, the mica has an average particle size of about 10 to 100 μm, and due to its high aspect ratio, it has a very strong gloss or pearly feeling, making it unsuitable for cosmetic compositions that express matte, natural skin.

Accordingly, a makeup cosmetic composition was prepared by replacing the mica with talc, but the formulation of the composition has poor floating and spreadability, making it difficult to use.

Therefore, the present invention sought to provide a makeup cosmetic composition that can reduce the shine and shine of the skin to create a natural skin expression, has excellent spreadability and spreadability of the formulation, and has excellent skin adhesion.

The present invention relates to a makeup cosmetic composition containing talc with an average particle size of 15 to 40 μm and polymethylsilsesquioxane (PMSQ) with an average particle size of 3 to 5 μm.

The talc is a pigment, and in the present invention, talc with an average particle size of 15 to 40 μm is used, and preferably, talc with an average particle size of 15 to 25 μm is used.

As mentioned above, mica was mainly used as a pigment in the past, but it was difficult to express matte, natural skin due to the characteristic of mica having a very strong gloss or pearly feeling.

In the present invention, by using talc with an average particle size of 15 μm to 40 μm, matte and natural skin expression can be achieved, and excellent pay-off and spreadability of the makeup cosmetic composition can be obtained.

If the average particle size of talc is less than 15 μm, the density of the makeup cosmetic composition increases and there is a problem of poor floating properties of the composition. In addition, if the average particle size of the talc exceeds 40 μm, the gloss of the talc increases, making it unsuitable for matte skin expression. In addition, particles break during the manufacture of the makeup cosmetic composition, and the formulation stability of the composition becomes very poor. It is not suitable for use as a makeup cosmetic composition.

In general, to improve the stability of semi-solid formulations, talc whose surface was coated with a coating material was mainly used. The coating material may be, for example, one or more selected from the group consisting of silicone-based compounds, ester-based compounds, and alkylsilane-based compounds.

However, talc whose surface is coated with a coating material has the problem of poor skin adhesion, which reduces the feeling of use, and has problems with poor spreadability and spreadability.

The talc of the present invention having an average particle size of 15 to 40 μm can exhibit excellent stability even without coating the surface by having the above average particle size. Therefore, the talc of the present invention having an average particle size of 15 to 40 μm is talc whose surface is not coated with a coating material, and thus can exhibit excellent skin adhesion.

The polymethyl silsesquioxane is a silicon powder, and in the present invention, polymethyl silsesquioxane with an average particle size of 3 to 5 μm is used.

In the present invention, by using polymethylsilsesquioxane with an average particle size of 3 to 5 μm, excellent pay-off and spreadability of the makeup cosmetic composition can be realized.

It is very difficult to manufacture polymethylsilsesquioxane with an average particle size of less than 3 μm, making it difficult to use polymethylsilsesquioxane with this average particle size in makeup cosmetic compositions. In addition, if the average particle size of the polymethylsilsesquioxane exceeds 5 μm, the flexibility of the formulation of the makeup cosmetic composition is reduced, resulting in poor formulation stability and floating properties.

The makeup cosmetic composition of the present invention may be in a semi-solid formulation. In the present invention, a semi-solid dosage form means a composition in the form of a dough or paste, which does not have flowability and does not break or break when dropped.

More specifically, the cosmetic composition of the present invention may be a semi-solid formulation having a hardness of 0.05 to 0.8 N as measured by a ball hardness tester. The above hardness was measured by filling a cream transparent container (white cap, 4cm diameter, 2.5cm height round container, Hayoungsang Co., Ltd.) with a makeup cosmetic composition, and using a ball-type spindle with a sun rheometer (SUN SCIENTIFIC Co.LTD, CR-500DX). The ball hardness was measured under the measurement conditions of measurement setting MODE 20, MAX 10kg, R/H HOLD, depth 8.0mm, and speed 600mm/m.

In order for the makeup cosmetic composition of the present invention to be in a semi-solid formulation, it may further include at least one selected from the group consisting of hydrocarbon-based oil, silicone-based oil, and silicone-based gel.

The hydrocarbon-based oil may include one or more selected from the group consisting of phytosqualane, isohexadecane, isodecane, undecane, squalane, hydrogenated polydecene, alpha-olefin oligomer, and hydrogenated polyisobutene. In the present invention, phytosqualane may be preferably used.

The silicone oil includes dimethicone, cyclomethicone, cyclophenylmethicone, capryldimethicone, caprylyltrimethicone, caprylylmethicone, cetearylmethicone, hexadecylmethicone, hexylmethicone, and laurylmethicone. Chicone, myrithylmethicone, phenylmethicone, stearylmethicone, stearyldimethicone, trifluoropropylmethicone, cetyldimethicone, polyphenylmethylsiloxane, dimethylpolysiloxane, methylphenylpolysiloxane, cyclopentasiloxane, decamethylcyclo At least one selected from the group consisting of pentasiloxane, cyclohexasiloxane, cycloheptasiloxane, cyclotetrasiloxane, cyclotrisiloxane, methylctrimethicone, diphenylsiloxyphenyltrimethicone, caprylylmethicone and phenyltrimethicone may include. In the present invention, dimethicone can be preferably used.

The silicone gel may refer to a silicone polymer alone or a mixture showing a gel state by dispersing two or more silicone polymers in a solvent. The silicone polymer may include dimethicone vinyldimethicone crosspolymer, polysilicon-11, polysilicon-15, It may be one or more types selected from the group consisting of polysilicon-8 and polysilicon-17. The type of solvent is not particularly limited as long as it can disperse the silicone polymer in the solvent, and any solvent used in the art can be used.

Also, Shinestu's KSG-15. 16. 18. 41, 42, 43, 44, 210, 310, 320, 330, 340, 710, 830, 840, Dow Corning EL-8051IN Silicone Organic Elastomer Blend, Dow Corning EL-8052IH It can be easily applied using commercially available raw materials such as Silicone Organic Elastomer Blend and Dow　Corning EL-8050ID Silicone Organic Elastomer Blend, but specially manufactured silicone gel raw materials according to the needs of those skilled in the art can also be applied, so it is limited to the above raw materials. That is not the case. In the present invention, a type in which dimethicone vinyl dimethicone crosspolymer is dispersed in dimethicone (KSG-16) can be preferably used.

The semi-solid formulation of the makeup cosmetic composition of the present invention can be divided into talc with an average particle size of 15 to 40 μm, polymethylsilsesquioxane with an average particle size of 3 to 5 μm, and other components.

The other ingredients may include one or more selected from the group consisting of hydrocarbon-based oil, silicone-based oil, and silicone-based gel.

The combined weight of talc and polymethylsilsesquioxane may be included in 40 to 80% by weight based on the total weight of the semi-solid formulation of the makeup cosmetic composition.

If the content is less than 40% by weight, the oil flows out of the makeup cosmetic composition formulation and is not prepared as a semi-solid, and the stability of the makeup cosmetic composition is poor. In addition, if the content exceeds 80% by weight, the makeup cosmetic composition may not clump together, making it difficult to manufacture it into a semi-solid form.

Additionally, talc having an average particle size of 15 to 40 μm and polymethylsilsesquioxane having an average particle size of 3 to 5 μm of the present invention may be mixed at a weight ratio of 4:1 to 1:1, preferably 2:1.

If the talc exceeds the weight ratio, the floating property of the makeup cosmetic composition is poor, and if the talc is less than the weight ratio, the oil absorption of the makeup cosmetic composition increases, which may cause a problem in which the composition is not manufactured as a semi-solid.

Ingredients other than the talc and polymethylsilsesquioxane may be included in an amount of 20 to 60% by weight based on the total weight of the semi-solid formulation of the makeup cosmetic composition of the present invention.

If the content is less than 20% by weight, the makeup cosmetic composition may not clump together, making it difficult to manufacture into a semi-solid form. If the content exceeds 60% by weight, the oil may flow out of the makeup cosmetic composition formulation and form a semi-solid form. There is a problem that it is difficult to manufacture.

In addition, the makeup cosmetic composition of the present invention includes additives to improve physical properties and product quality, and the additives may further include colorants, preservatives, emulsifiers, dispersants, or thickeners.

In addition, the makeup cosmetic composition of the present invention can be used as a primer, eye makeup base, eye shadow, blusher, highlighter, bronzer, It can be formulated into makeup base, foundation, etc. In addition, it can be formulated in various fields that require matte skin expression, such as hairline and body, as well as face makeup. The composition of each of these formulations may contain various bases and additives necessary and appropriate for the formulation of the formulation, and the types and amounts of these components can be easily selected by those skilled in the art.

Hereinafter, examples, comparative examples, and experimental examples will be described to aid understanding of the effects of the present invention. However, the following description is only an example of the content and effect of the present invention, and the scope and effect of the present invention are not limited thereto.

Example 1 and Comparative Examples 1 to 4. Preparation of makeup cosmetic composition

According to the composition in Table 1 below, the semi-solid formulations of Example 1 and Comparative Examples 1 to 4 were prepared. A makeup cosmetic composition was prepared.

(Unit: weight%) Example 1 Comparative Example 1 Comparative Example 2 Comparative Example 3 Comparative Example 4 Talc average particle size 34 - - 34 - 18μm average particle size - - - - 34 45μm Talc coated with alkyl silanes average particle size - 34 - - - 9μm Myka - - 34 - - polymethylsilsesquioxane average particle size 17 17 17 - 17 4μm average particle size - - - 17 10μm Vinyl dimethicone/methicone silsesquioxane crosspolymer One One One One One TiO ₂ 3 3 3 3 3 iron oxide 16 16 16 16 16 Phytocus allan 3 3 3 3 3 Dimethicone 24 24 24 24 24 Dimethicone/Dimethicone Vinyl Dimethicone Crosspolymer 2 2 2 2 2

The makeup cosmetic compositions of Example 1 and Comparative Examples 1 to 3 were all formulated, but in the makeup cosmetic composition of Comparative Example 4, the average particle size of talc exceeded 40 μm, causing the particles to break, resulting in a stable formulation. Could not be manufactured.

Experimental Example 1. Evaluation of gloss of makeup cosmetic composition

The makeup cosmetic compositions prepared in Example 1 and Comparative Examples 1 to 3 were uniformly applied onto glossy white paper and measured at 60° using BYK micro-TRI-gloss. The results are shown in Table 2 below. indicated.

(Unit: Gloss Units) Example 1 Comparative Example 1 Comparative Example 2 Comparative Example 3 5.3 5.2 8.1 not measurable

From the results in Table 2, the makeup cosmetic composition of Example 1 containing talc with an average particle size of 15 to 40 μm was not measured to have high gloss. In addition, the average particle size was less than 15 μm and the gloss of the makeup cosmetic composition of Comparative Example 1 using talc whose surface was coated with alkylsilane was not measured to be high.

However, it was confirmed that the gloss of the makeup cosmetic composition of Comparative Example 2 containing mica instead of the talc of the present invention was higher than that of Example 1 and Comparative Example 1.

In addition, the makeup cosmetic composition of Comparative Example 3 did not have a uniform formulation and had poor floating properties, making uniform application difficult, making it impossible to measure gloss.

Figure 1 shows a comparison of the appearances of Example 1 and Comparative Example 2, and Figure 2 shows flash photography after applying the makeup cosmetic composition to black leather instead of white paper. In Figure 1, it can be seen that Comparative Example 2 has a shiny pearly feel, and in Figure 2, it can be seen that Comparative Example 2 has a glossy feel.

This is due to mica, which has strong gloss or pearly properties, and as a result, it can be seen that when mica is used, it is difficult to express matte skin due to the gloss and pearly feeling.

Therefore, it can be seen that the makeup cosmetic composition of the present invention containing talc with an average particle size of 15 to 40 μm is capable of expressing matte, natural skin.

Experimental Example 2. Evaluation of feeling of use of makeup cosmetic composition

2-1. Pay-off evaluation

After rubbing the makeup cosmetic compositions prepared in Example 1, Comparative Example 1, and Comparative Example 3 three times with a puff, the surface of the puff was observed with the naked eye, and the results are shown in Figures 3 to 6.

It was confirmed that the makeup cosmetic composition of Example 1 had excellent floating properties (FIG. 3).

On the other hand, the makeup cosmetic composition of Comparative Example 1 was coated with alkylsilane on the surface and used talc with an average particle size of 9 μm, and the cosmetic composition was not taken into the puff (FIG. 4).

The makeup cosmetic composition of Comparative Example 3 used polymethylsilsesquioxane with an average particle size of 10 μm, and the cosmetic composition was taken unevenly on the puff (Figure 5), and tearing or tearing of the formulation was observed (Figure 6) ).

From this, it can be seen that the makeup cosmetic composition of the present invention containing talc with an average particle size of 15 to 40 μm and polymethylsilsesquioxane with an average particle size of 3 to 5 μm has excellent floating properties.

2-2. Spreadability evaluation

The makeup cosmetic compositions prepared in Example 1, Comparative Example 1, and Comparative Example 3 were taken with a puff and applied to the same surface by pushing it once in one direction, and the spreadability was evaluated by measuring the application distance.

Example 1 was measured at 6.3 cm, Comparative Example 1 was measured at 3.9 cm, and Comparative Example 3 was measured within 2 cm (FIGS. 7 and 8).

In particular, the makeup cosmetic composition of Comparative Example 3 was observed to have parts of the composition being pulled unevenly.

From this, it can be seen that the makeup cosmetic composition of the present invention containing talc with an average particle size of 15 to 40 μm and polymethylsilsesquioxane with an average particle size of 3 to 5 μm has excellent spreadability.

2-3. Skin adhesion evaluation

The makeup cosmetic compositions prepared in Example 1 and Comparative Examples 1 to 2 were evaluated for skin adhesion.

In a consumer panel test, 20 female consumers in their 20s and 30s were asked to use the product for 3 days, and then a comparative evaluation of skin adhesion was conducted on a 5-point scale and averaged. The results are shown in Table 3 below.

Example 1 Comparative Example 1 Comparative Example 2 4 2 4

<Evaluation criteria>

5 points: Excellent skin adhesion when applied

4 points: Excellent skin adhesion upon application

3 points: Average skin adhesion when applied

2 points: There is almost no sense of adhesion to the skin when applied, and there is a slight feeling of sticking.

1 point: When applied, there is no feeling of adhesion to the skin and it feels like it is peeling off.

From the results in Table 3, it was confirmed that the makeup cosmetic compositions of Example 1 and Comparative Example 2 had excellent skin adhesion.

However, the makeup cosmetic composition of Comparative Example 2, in which the average particle size of talc was less than 9 μm and the talc surface was coated with alkylsilane, showed poor skin adhesion.

From this, it can be seen that the average particle size of talc is 15 to 40 μm, and the makeup cosmetic composition of the present invention, which is not coated on the surface of talc, has excellent skin adhesion.

From the above results, the makeup cosmetic composition of the present invention containing talc with an average particle size of 15 to 40 μm and polymethylsilsesquioxane with an average particle size of 3 to 5 μm has low gloss and does not cause shine, creating a matte, natural look. It was confirmed that skin expression was possible, and that the composition had excellent floating properties, spreadability, and skin adhesion.
