Description

Lip cosmetic composition

The present invention relates to a lip cosmetic composition, and more particularly, to a lip cosmetic composition comprising a nonvolatile dimethylpolysiloxane and a volatile silicone derivative oil as a blocking agent, and a hydrophobic silica as a thickener. The present invention is applied to a color cosmetics such as lipstick or lip pencil, forming a transparent film with strong water and oil resistance on the color cosmetics to prevent the color cosmetics from being buried or erased in other containers while maintaining the color of the color image as it is It provides a lip cosmetic composition that can be.

In general, lipsticks are made by dispersing organic and inorganic pigments in oily substances such as castor oil and mixing them with waxy substances.These lipsticks are only attached to the skin by oily substances, so they are in contact with the lips when eating foods. It has been pointed out that water is a problem that lipstick contents are smeared on clothes, bowls, cutlery, etc. and carelessly, and the contents applied to lips are erased.

Thus, the present inventors have studied diligently to solve the problem of the above-described color cosmetics for lips, when applying a transparent film having strong water resistance and oil resistance on the color cosmetics, it is possible to prevent mixing with the color cosmetics by strong oil resistance In addition, since the transparent film is formed, the color of the color makeup can be maintained as it is, and the color makeup due to contact with food can be prevented by strong water resistance and oil resistance. The present invention has been completed with the idea that it can be prevented.

That is, an object of the present invention is to provide a lip cosmetics that can form a transparent film having a strong water resistance and oil resistance by applying over the lip cosmetics.

In order to achieve the above object, the composition of the present invention contains a nonvolatile dimethylpolysiloxane and a volatile silicone derivative oil in a composition ratio of 1/5 to 5/1 as a blocking agent, and contains hydrophobic silica as a thickener. It features.

Dimethyl polysiloxane used in the present invention as a blocking material having a strong film resistance of water resistance and oil resistance is represented by the following structural formula (I), a non-volatile material having a kinematic viscosity of 2.0 ~ 100,000 cs, selected from these alone or two The above mixture is used.

In the present invention, the volatile silicone derivative oil used to uniformly and harden the film of the nonvolatile dimethylpolysiloxane component is represented by the following structural formula (II), and has a dimethylpolysiloxane having a kinematic viscosity of 0.3 to 2.0cs. , A single or a mixture of two or more selected from cyclomethicone represented by the following structural formula (III) or (IV) is used.

Has an excellent effect at a composition ratio in the range of 1/5 to 5/1. In addition, the composition of the present invention contains the aforementioned nonvolatile and volatile silicone derivative oil mixture in an amount of 10 to 99.9% by weight based on the total weight of the composition.

The silicone derivative oil, which is a blocking material used in the present invention, has a smooth and refreshing feeling and breathability, has excellent film forming ability with strong water resistance and oil resistance, and can impart skin protection effect and is also harmless to human body. As a cosmetic, it has been widely used in basic cosmetic products such as skins, lotions, creams, hair cosmetics, and makeup products.

In particular, dimethylpolysiloxane can adjust the viscosity according to the degree of polymerization, it is characterized by a very stable and transparent fluid physically and chemically. In general, the hydrocarbon compound has a waxy physical property when the molecular weight is about 100,000, while the high molecular weight dimethylpolysiloxane has a property of forming a film having high water resistance and oil resistance as a fluid of high viscosity. Cyclomethicone, a compound having a low molecular weight of dimethylsiloxane or dimethylsiloxane, is volatile in a short time at room temperature.

The present invention utilizes the properties of nonvolatile high molecular weight dimethylpolysiloxanes and volatile low molecular weight silicone derivative oils. In other words, the high molecular weight dimethylpolysiloxane is non-volatile and does not mix with water, and also can form a water-resistant and oil-resistant film that is not easily mixed with oily materials, and the non-volatile dimethyl polysiloxane having such characteristics is a volatile silicone When used in combination with a derivative oil in an appropriate amount, it can be applied to the lips to volatilize the volatile components, thereby making the coating of non-volatile components even and hard.

On the other hand, silicone is not mixed with water, and it is very difficult to increase because it is not compatible with oily substances, because it does not maintain the proper viscosity required for cosmetic use, can not be used to reduce the appropriate amount when using cosmetics, There is a problem in that the adhesion to the skin falls off and does not properly exhibit the characteristics of the protective film. In order to solve such a problem, in addition, in the case of the blocking cream, the use of the thickener is inevitable in view of the fact that the blocking property is improved by maintaining a high concentration of the material for blocking. In fact, in the test examples described later, only the blocking agent was found to be weak in protecting the color cosmetics.

Therefore, the present invention is characterized in that hydrophobic silica is used as a thickener capable of appropriately increasing the composition while maintaining the transparency of the blocking agent.

The silica used to prepare the hydrophobized silica used in the present invention is a fine size silica gel, which is mixed with an acid and a silicate dissolved therein to make a hydrogel, finely crushed and washed to remove acids and salts, and flame treatment. The large surface area and porosity of the gel were maintained. Hydrophobized silica reacts silanol groups with at least one hydrophobic treatment agent selected from dimethyldichlorosilan, dimethylpolysiloxan, hexamethyldisiloxan or trimethoxyoctylsilan to impart hydrophobicity. will be. At this time, the hydrophobic treatment agent is blended in an amount of 1 to 50% by weight based on silica.

The hydrophobic silica had an effect of 0.1 to 20% by weight based on the total weight of the composition, and particularly good at 2 to 10% by weight.

In addition to the blocker and the thickener described above, the lip cosmetic composition of the present invention may contain various nutrients within a range that does not reduce the transparency and the desired effect of the cosmetic of the present invention. For example, grape seed oil, carrot oil, sauer oil, camellia oil, rice bran oil, rose mario oil, rose hip oil, macadamia nut oil, meadowfoam seed oil, cottonseed oil, borage oil, chaflower oil, avocado oil Vegetable oils such as apricot kernel oil, palm oil, orange oil, olive oil, crescent oil, sesame oil, tunesol oil, soybean oil, coconut oil, palm oil, palm kernel oil, sunflower oil, hotspot oil, castor oil and jojoba oil; Animal oils such as lanolin oil and mink oil; Or other synthetic oils may be used. Furthermore, protein derivatives derived from animals and plants can also be used. These other nutrients are preferably contained in an amount of 0.1 to 20% by weight based on the total weight of the composition in view of the desired effect. In addition, preservatives, pigments, flavorings, sunscreens and the like can be added to enhance the cosmetic effect.

The lip cosmetic composition according to the present invention may take the form of a gel, stick, roll-on or paste in its formulation.

[Test Example 1] Buried degree comparison

Divided 14 women of 20-40 year old sensory test personnel into two groups of A and B, and after applying lipstick, the blocking creams prepared in Examples 1 to 4 and Comparative Examples 1 to 3 were divided thereon. After using it, group A was wiped with tissue and smeared on tissue, and group B had coffee after comparing the degree of stain on glass. The evaluation was carried out on all 7 members in each group. The average score was calculated by giving 3, 2, 1, and 0 points from the most severe burial. The results are shown in Table 1 below.

As can be seen from the results of Table 1 above, the blocking cream according to the present invention was superior to the blocking effect of Comparative Example 1 without the use of a thickener, and Comparative Examples 2 and 3 are commonly used as blocking creams. The blocking effect was superior.

[Test Example 2] Comparison of transparency and persistence of color

Twenty-four women, 20-40 years old, were divided into three groups A, B, and C. At 10 am, red lipstick in group A, pink lipstick in group B, and orange lipstick in group C. After correcting, one person in each group did not apply the blocking cream, and the remaining seven people were allowed to use the blocking cream prepared in Examples 1 to 4 and Comparative Examples 1 to 3 one by one. The evaluation of the transparency of the color was conducted to all agents in each group, and according to the degree of the difference compared to the color of the lipstick of the person who does not apply the blocking cream, depending on the degree of difference between the clouded color or the lack of transparency, 3 points, 2 points, 1 point and 0 point were given and the average point was computed. The results are shown in Table 2 below.

In addition, the evaluation of the persistence of color was visually observed at 5 pm, and the average point was calculated by giving 3, 2, 1, and 0 points from the excellent color persistence. The results are shown in Figure 3.

Comparative Examples 2 and 3 contain a high concentration of blocking substances, but in Comparative Example 2 was made of a white creamy form, and when applied on the color make-up, both Comparative Examples 2 and 3 formed an opaque white film The color of the makeup was not expressed in its original color. Therefore, even if it functions as a blocking cream to protect the skin, a function to maintain the color makeup can be expected.

As can be seen from the above test examples, the increased silicone derivative according to the present invention protects and maintains the color tone applied to the skin as it is, and furthermore, maintains the color as the original color, and contains a high concentration. The effect of preventing the makeup pigment from staining or erasing on other objects by the function of the barrier material was superior to the example of the perfluorinated ether polymer that has been used as a barrier material in the past.
