Description

[0001] The present invention relates to a cosmetic composition with low turbidity,

To a makeup cosmetic composition with reduced turbidity and a method for producing the same.

Titanium dioxide is a representative powder that has been used in conventional color cosmetic compositions. Among the color cosmetic compositions, the 'ball touch' cosmetics contained a large amount of titanium dioxide, and thus the turbidity was high. Due to the high turbidity, there was a limit to expressing clear color like watercolor, and it was difficult to express gradation color for natural makeup. In addition, titanium dioxide has a disadvantage in that it is difficult to produce clear color due to excessive coloring and pore-pitting phenomenon during color development.

Among the color cosmetics, ball touch is a type of cosmetics that is mainly applied to the face ball area to give various effects such as giving a color effect to the skin or enhancing the cheekbones.

Therefore, in order to solve the above problems, there is a need to develop a cosmetic composition that can be used in color cosmetics because it has substantially no turbidity and has a low coloring power and adhesion.

One aspect provides a makeup cosmetic composition comprising a volatile oil and substantially free of titanium dioxide.

Further, another aspect provides a method for producing the makeup cosmetic composition.

One aspect provides a makeup cosmetic composition comprising a volatile oil and substantially free of titanium dioxide.

The cosmetic composition according to one aspect does not substantially contain titanium dioxide in order to improve the coloring phenomenon, which is caused by pit pores which are caused by the titanium dioxide used in the conventional color cosmetic composition, The composition of the present invention is characterized in that it has reduced turbidity and transparency as compared with the cosmetic composition and also has a finished feeling and a soft feeling by containing volatile oil.

The cosmetic composition is characterized by reduced turbidity. In the present specification, "turbidity" refers to a degree of turbidity of the composition. If the turbidity of the color cosmetic composition is high, the color expressive power is low, it is difficult to give a transparent feeling, and it is difficult to produce a gradation color expression. The cosmetic composition according to one aspect is characterized in that turbidity is reduced because it does not substantially contain titanium dioxide.

The cosmetic composition is substantially free of titanium dioxide. The term " substantially free of titanium dioxide " as used herein means less than about 0.5%, less than about 0.45%, less than about 0.4%, less than about 0.35% Less than about 0.3 wt%, less than about 0.25 wt%, less than about 0.2 wt%, less than about 0.15 wt%, less than about 0.1 wt%, less than about 0.05 wt%, less than about 0.04 wt% , Or less than about 0.01% by weight, or does not include titanium dioxide.

The titanium dioxide is an inorganic synthetic powder and may be used interchangeably with powders such as zinc oxides having similar properties to titanium dioxide corresponding to white pigments and may include these.

As used herein, the term " volatile oil " is not limited to the types of volatile oils generally used in cosmetic compositions as long as they do not significantly affect the viscosity of the cosmetic composition. The volatile oil may be at least one selected from the group consisting of volatile silicone oils, for example, caprylylmethicone, dimethicone, methyltrimethicone, cyclopentasiloxane, cyclohexasiloxane, isododecane, and isohexadecane have. Specifically, the viscosity of the volatile oil is about 6000 to 12000 rpm or about 7000 to 10000 rpm based on # 64 pins, 12 rpm, 1 minute using a rotational viscometer, and has a finishing feel, .

The volatile oil can improve the feeling of use of the cosmetic composition. For example, it is possible to provide a feeling of lightness and softness when applying a cosmetic composition, and to give a finish feeling that is volatilized and smoothed after being applied without matting.

The volatile oil may be present in an amount of about 20 to 30% by weight, about 21 to 30% by weight, about 22 to 30% by weight, about 22 to 29% by weight, about 22 to 28% by weight, % ≪ / RTI > by weight. When the volatile oil is contained in an amount of less than about 20 wt%, there may arise a problem that the smell of finish, light and soft feeling, which is an effect due to the volatile oil, is lowered. If the volatile oil is contained in an amount of more than about 30% by weight, the viscosity of the composition may be lowered and phase separation may occur.

The cosmetic composition may further include a modified alcohol.

In the present specification, the term "denatured alcohol" refers to one which is made to be distinguished from beverage alcohol by adding a small amount of denaturant (methanol, benzene, benzine, etc.) in order to prevent it from being used for beverage. The denatured alcohol may include ethanol.

The modified alcohol may comprise about 5 to 10 wt%, about 4.5 to 8 wt%, or about 4 to 7 wt% based on the total weight of the cosmetic composition. When the modified alcohol is less than about 5% by weight, it is difficult to provide a cool finish. If the denatured alcohol is more than about 10% by weight, irritation to the skin may occur.

The cosmetic composition may further comprise an extender pigment. The extender pigment may be a nylon powder such as nylon-5 or nylon-12, a spherical powder such as silica, urethane powder, polymethylmethacrylate (PMMA), polymethylsilsesquioxane (PMSQ), calcium aluminum borosilicate , And plate-like powders such as talc, mica, and synthetic fluorofluorite.

The plate-like powder may be included in an amount of about 1 to 5% by weight based on the total weight of the cosmetic composition.

The spherical powder may be a fine spherical powder, and may be included in an amount of about 0.1 to 2% by weight based on the total weight of the cosmetic composition.

Since the cosmetic composition includes a plate-like powder and a spherical powder, an excellent rolling effect can be imparted to the composition, and thin and smooth spreadability can be exhibited through the composition.

The cosmetic composition may further comprise a silicone component. The silicon component may include distearmonium hectorite, phage-10 dimethicone, cetylpiperazine / phyphage-10/1 dimethicone, or combinations thereof. The distearammonium hectorite is a viscosity modifier and can prevent the viscosity of the composition from becoming too low. The above-mentioned fat-10 dimethicone, cetylpiperazine / piperazine-10/1 dimethicone can be used as an emulsifier.

 The cosmetic composition may be a W / S type (water in silicon type). W / S type is silicone emulsion type, and it has advantage of light feeling because there is no oil.

Since the cosmetic composition has a W / S type, the effect of reducing the turbidity of the composition is excellent.

The cosmetic composition is a cosmetic composition for make-up, and can be used in color cosmetics. The color cosmetics may include, for example, a ball touch (or blusher), a shading, a lip product, and the like, preferably, but not exclusively, a ball touch.

One of ordinary skill in the art can select any additional components and / or amounts thereof so that the beneficial properties of the composition according to the present disclosure are not adversely affected or substantially not affected by the anticipated addition.

The cosmetic composition may contain at least one selected from the group consisting of preservatives, stabilizers, surfactants, thickeners, solubilizers, moisturizers, emollients, ultraviolet absorbers, preservatives, bactericides, emulsifiers, antioxidants, pH adjusting agents, organic and inorganic pigments, And may further contain additives commonly used in the art. The amount of the additional ingredient such as the preservative may be easily selected by a person skilled in the art within the range not impairing the object and effect of the present invention, and the amount thereof may be 0.001 to 40% by weight based on the total weight of the composition.

Other aspects include oily phases including volatile oils; A method of making a cosmetic composition for make-up comprising mixing an aqueous phase containing a denatured alcohol, wherein the cosmetic composition does not actually contain titanium dioxide.

The cosmetic composition according to an aspect of the present invention may contain a volatile oil not containing titanium dioxide which increases the turbidity, and may have a feeling of light feeling and a transparent feeling, so that it can be used in a cosmetic composition for color vision.

Hereinafter, the present invention will be described in more detail with reference to examples. However, these examples are for illustrative purposes only, and the scope of the present invention is not limited to these examples.

Example 1 and Comparative Example 1-2: Preparation of cosmetic composition

According to the contents and contents of the following Table 1, talc and mica were first added to silicon containing cyclopentasiloxane, distearamonium hectorite, phage-10 dimethicone, cetylpiperazine / piperidine-10/1 dimethicone, Red No. 226 and yellow iron oxide were mixed and dispersed at 3500 rpm for 10 minutes. The process is a heating process (70-75 ° C). After that, the water containing the purified water, glycerin and preservative was mixed and emulsified at 6000 rpm for 10 minutes, and then the process was completed through cooling, perfume injection and defoaming. As a result, a lotion-formulated cosmetic composition was obtained. Unless otherwise noted, the component content is in wt.%.

Example 1 contains 22% by weight of cyclopentasiloxane which is a volatile oil without titanium dioxide, Comparative Example 1 contains 1.5% by weight of titanium dioxide and 18% by weight of cyclopentasiloxane to increase the content of titanium dioxide And Comparative Example 2 was prepared so as to contain 0.5 wt% of titanium dioxide and 18 wt% of cyclopentasiloxane to lower the content of titanium dioxide so as not to substantially contain titanium dioxide.

Fig. 1 is a photograph of the cosmetic composition applied in Example 1 (left) and Comparative Example 1 (right). (a) Apply on white background (b) Drop on arm (c) Apply on arm.

2 is a photograph of a cosmetic composition applied to Example 1 (left) and Comparative Example 2 (right). (a) Apply on white background (b) Drop on arm (c) Apply on arm.

As shown in Figs. 1 and 2, Example 1 and Comparative Example 1-2 contain the same kind and the same amount of coloring matter, but the difference in turbidity is apparent depending on the content of titanium dioxide, and it is confirmed that it is difficult to express a desired color Respectively. This turbidity increase phenomenon is observed even when 0.5% by weight of titanium dioxide is contained, so that it is preferable that titanium dioxide is contained in an amount of less than 0.5% by weight. This was the same when applied to the arm as well as when applied to the white background.

Therefore, the composition of Example 1 is low in turbidity and is suitable for expressing a transparent color feeling.

Experimental Example 1: Sensory Evaluation on Feeling

Experiments were conducted to evaluate the feeling of use of the cosmetic compositions of Example 1 and Comparative Example 1-2.

Specifically, Example 1 and Comparative Example 1-2 were applied and applied to balls of 20 subjects. The light feeling, the adhesion and the transparent coloring ability of each subject were evaluated, and the average values of these were shown in Table 2. Evaluation scales were performed according to the criteria shown in the table below.

<Rating scale: 1 point - Very poor, 2 points - Poor, 3 points - Average, 4 points - Good, 5 points - Very good>

Light feeling Adhesion Transparent color Example 1 4.6 4.6 4.5 Comparative Example 1 3.4 3.2 2.9 Comparative Example 2 3.7 3.8 3.0

As a result of evaluation of overall feel, adhesion and coloring power as shown in the above Table 2, when evaluating based on the three evaluation items, the cosmetic composition according to Example 1 had an average light feeling of 4.6, an adhesion of 4.5, 4.5 points, whereas Comparative Example 1-2 showed a lower average value than Example 1 in the overall evaluation.

Therefore, if the cosmetic composition of Example 1 is used as a color cosmetics, it has a merit that it does not substantially contain titanium dioxide, so it has a merit of showing transparency and color, but it gives a light and soft feeling due to volatile oil, And an excellent effect of adhesion can be obtained.
