The present invention relates to a cosmetic composition for minimizing the rolling and agglomeration phenomenon during make-up. More specifically, it contains less emulsified silicone emollients to enhance the skin absorption of cosmetics, and by using oil-soluble powders to absorb sebum and oil present on the skin, minimizing the rolling of makeup make-up after basic makeup and improving aggregation One cosmetic composition relates.

Makeup can be divided into two categories: basic makeup and makeup makeup. Basic makeup refers to makeup that enhances the functions of the skin such as moisturizing, whitening, elasticity, wrinkle improvement, and soothing, such as supple cosmetics, nourishing cosmetics, essences, lotions, and creams commonly used in daily life. Means a makeup that imparts color tone or covers a flaw, such as lipstick. In general, the makeup after the basic make-up, many people experience a discomfort in the jungle during makeup makeup. In fact, according to a survey, 16.3% of the respondents selected “I don't get well” among the items that I wanted to improve while wearing makeup. In addition, 72% of the “cosmetic jungle” is accounted for by the jungle because most of the causes of makeup loss [Pacific CS voice Net 2003 ~ 2004-Voice of customers].

Many studies have been made on the cause of such cremation. Excessive polymers and oils remaining on the skin after applying the basic cosmetics are entangled with the excess powders and polymers contained in the makeup cosmetics, and it is believed that the rolling phenomenon occurs [Koichi Nomura (Fragrance Jounal, 2003.4): Mechanism of]. We need a shear stress of 1.0 to 100 s ^-1 to apply cosmetics by hand and a very large shear stress of 100 to 10000 s ^-1 to apply it to the face and skin. When such a large external force is applied, the various components in the cosmetics form a new arrangement. In the process, the components in the basic cosmetics, the components in the makeup cosmetics or the components between the two cosmetics are entangled or aggregated together. However, the reality is that research on this is not systematically established but merely phenomenological analysis. In fact, the polymers used in basic cosmetics and makeup cosmetics are very diverse, ranging from carbomers, hydroxyethyl acrylate / sodium acryloyldimethyltaurate copolymers, xanthan gum and cellulose gums. Each property is also different. In addition, there are also thousands of powders, such as oils and powders used in cosmetics, showing different physical properties. Therefore, it is difficult to find and quantify the main factors causing the jungle among these various components.

Accordingly, the present inventors have conducted research to solve the above-mentioned conventional problems, by using a combination of silicone emollients and nonionic surfactants to enhance the skin absorption of the cosmetics, and the excess remaining on the skin by using a useful powder. The present invention finds that it is possible to improve the jungle phenomenon during make-up by removing oils by adsorbing oil, and removing or uniformly distributing sebum evenly by containing an appropriate amount of ethyl alcohol. Was completed.

Accordingly, it is an object of the present invention to provide a cosmetic composition that minimizes the rolling of the makeup make-up.

In order to achieve the above object, the cosmetic composition according to the present invention is (a) 2.00 to 8.00% by weight of a low molecular weight silicone emollient having a molecular weight of 300 ~ 2000 based on the total weight of the composition; (B) 0.10 to 3.00 wt% of an oil-soluble powder; (C) 0.5-10.0 wt% of nonionic surfactant; and (d) 2.00-10.00 wt% of ethyl alcohol.

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

Silicone emollient (silicone emollient) in the composition according to the invention is not limited in kind, but preferably contains at least one selected from the group consisting of dimethicone (cyclomethicone) and cyclomethicone (disperse in the water phase) The internal form of the formulation in the formulated form.

One of the causes of the makeup jungle is that the makeup phenomenon is applied as the makeup cosmetics are applied in the state that the basic cosmetics are not completely absorbed by the skin, the jungle phenomenon occurs by the interaction between the components of the two cosmetics. In other words, the rate of absorption of basic cosmetics is a major variable in cremation. Therefore, it is possible to minimize the make-up by improving the skin absorption of the basic cosmetic using a low molecular weight silicone emollients. In the case of high molecular weight silicone emollients, the skin absorption is slow and the diffusion rate into the air is high, and thus the amount of residual silicone emollients is caused to physically interact with the makeup cosmetics to cause the makeup.

Therefore, it is preferable to use a low molecular weight silicon emulsifier having an average molecular weight of 300 to 2000 as the silicon emollient. This is because when the average molecular weight is greater than 2000, it causes a large amount of stickiness due to the increase in the molecular weight. In fact, stickiness is often influenced by intermolecular attraction, but as molecular weight increases, the intermolecular van der Waals attraction increases, which also affects stickiness. In addition, if the molecular weight is too large, the absorption and evaporation rate of the cosmetics is drastically reduced, so that the amount of residual residue on the skin is large, which appears as a squeeze during makeup. On the other hand, if the average molecular weight is less than 300, the stability of the formulation may be unstable in terms of practicality.

In addition, the content of the silicone emollient is preferably contained in 2.00 to 8.00% by weight based on the total weight of the composition. This is because the use of less than 2.00% by weight does not secure sufficient silicone emulsifier for the dispersion of oil-soluble powder, which adversely affects the stability of the formulation. Absorption will naturally slow down because it will remain and may affect the makeup of the makeup make-up.

The oil-soluble powder in the composition according to the present invention preferably contains at least one member selected from the group consisting of polymethylsilsesquioxane and talc.

 The above-mentioned oil-soluble powder is used because the skin of the human body is closer to lipophilic than hydrophilic. In other words, when the oil-soluble powder is used, the cosmetics are evenly applied on the skin, so it is easy to integrate with the skin, and the oils and dusts from various types of sebum secreted from the skin and the external environment are adsorbed by the oil-soluble powder. Makes it softer and more flexible. Applying makeup cosmetics in this situation can significantly improve the phenomenon of sebum, grease, lumping, rolling, and agglomeration. On the other hand, when the water-soluble powder is used, the cosmetics are not adhered to the skin efficiently, so the appearance occurs on the skin, and thus, itself acts as a cause of the jungle of makeup.

In addition, the content of the oil-soluble powder is preferably contained in 0.10 to 3.00% by weight relative to the total weight of the composition. This is less than 0.10% by weight, sebum adsorption by the oil-soluble powder does not appear effectively, when used more than 3.00% by weight of the powder is not good stability of the formulation by using excessive powder, the powder itself beyond the sebum adsorption function of the powder Because it causes the jungle.

The nonionic surfactant in the composition according to the present invention is not limited in kind, but is selected from the group consisting of sorbitan sesquioleate, polysorbate, hydrogenated lecithin, dimethicone copolyol, and PIG-100 stearate. It is preferable to contain one or more selected.

In addition, the content of the nonionic surfactant is preferably contained in 0.5 to 10.0% by weight based on the total weight of the composition. This is because the silicone dispersion formulation is unstable when used in a small amount of less than 0.5% by weight, and the internal and external wounds are separated when stored for several months, and when used in excess of 10.0% by weight, the skin irritation problem is caused by the surfactant.

Ethyl alcohol in the composition according to the present invention makes the skin fresher and softer during basic makeup. In addition, by removing or evenly distributing oil components that are unevenly distributed on the skin, it reduces the slippage of the next makeup cosmetics.

In addition, the ethyl alcohol is more than 99% purity is preferably contained 2.00 ~ 10.00% by weight relative to the total weight of the composition. Too much amount of 10.00% or more causes irritation to the skin and eyes, and an unpleasant odor. If a little amount of 2.00% or less is used, the absorption and evaporation rate of the ethanol use is insignificant and unevenly distributed. This is because the function of removing or evenly redistributing sebum does not appear significantly.

The basic cosmetic composition according to the present invention is not particularly limited in its formulation, but it is a softening longevity, nourishing longevity, massage cream, nutrition cream, pack, gel, essence, lipstick, makeup base, foundation, lotion, ointment, gel, cream, patch Or a formulation of a spray.

Hereinafter, the present invention will be described in more detail with reference to Examples and Comparative Examples, but the present invention is not limited only to these examples.

Test Example 3 Coating Uniformity Measurement Test Through Three-dimensional Stereoscopic Image

The formulations of Examples 1 to 4 and Comparative Examples 1 and 2 were applied to the artificial skin, and a foundation containing a fluorescent substance was applied after a predetermined time (5 minutes). Then, the uniformity of the coating was confirmed through a three-dimensional stereoscopic image using a confocal microscope, and the results are shown in FIG. 1.

The three-dimensional stereoscopic image of the confocal microscope means that the color is red as the system gets thicker and the thinner the system becomes blue. Therefore, when viewed in the color of one system, it can be evaluated that the uniform coating. However, when red and blue are scattered, it suggests that the uniformity of the application is very low. Therefore, when looking at the results, it was confirmed that in Comparative Example 1 was applied very unevenly, in the case of Examples 1 to 3 uniformly applied.

As described above, in the present invention, by using a silicone emulsifier having a low molecular weight, it enhances skin absorption of the basic cosmetic and minimizes makeup makeup after the basic cosmetic by absorbing sebum and oil present in the skin through the use of an oil-soluble powder. It was. In addition, by applying the appropriate amount of ethyl alcohol to improve the uniformity of the makeup make-up and gave the formulation a fresh usability. As a result, the composition showed an excellent makeup jungle improvement effect.
