Description

Lip cosmetic composition

The present invention relates to a lip cosmetic composition with high color rendering without color blocking phenomenon and dry feeling.

Lipsticks are usually oily formulations, including waxes, oils, pigments and powders. The wax maintains the shape of the lipstick, the oil gives a luxurious feeling of use and gloss, the pigment acts as a pigment and/or dye to give a sense of color, and the powder is used to improve the ductility, adhesion and durability, and at the same time to achieve a matte texture.

With the changes of the times, the fashion trend of makeup has also changed. Until the 1990s, lipsticks with matte and opaque makeup were mainly used, but after 2000, the transparency and moisturizing feeling of lip gloss or lip gloss were emphasized. The above-mentioned lip gloss or lip gloss has the advantage of being light and thin in use, but has the problem that the color lasting power and adhesion are weak and it is easy to take off the makeup.

Recently, in addition to lipsticks made with wax, various forms of lipsticks such as lip crayons, lip markers, lip glazes, lip glosses, lip gloss oils, and lip pencils are popular, as well as lipsticks with bright colors and high color rendering. .

High color rendering lipstick refers to the mouth that adheres to the lips and maintains it for a long time. Red, with a vivid sense of color. The aforementioned adhesion and durability are related to the powder in the composition of the lipstick.

As described above, the powder is related to the extensibility of the lipstick, that is, the degree of ease of application. Generally, if there are more spherical powders, the lipstick has soft extensibility. Also, the higher the powder content, the higher the adhesion of the lipstick to the lips.

High color rendering lipsticks use more than 10% by weight of excessive powder to achieve high color rendering and color durability. It has a dry and matte matte feel and has a soft makeup feel. However, the high color rendering lipstick has no oil content, so it has the following problems: the stretchability is relatively dry, the color is unevenly applied, and the dryness and keratin are induced over time, causing the lips to dry and dry, and the color floats or jams. Makes cuticles or wrinkles stand out.

Therefore, in order to overcome the dry feeling, a method of adding a composition such as a moisturizer or oil has been proposed.

In Korean Published Patent No. 2001-0110563, a perfluoroethyl alkyl polydimethylsiloxane, alkyl polydimethylsiloxane, vegetable polysaccharides and plate-like powder are proposed to prevent lips. A lip cosmetic composition that dries, moisturizes and gives gloss.

In addition, in Korean Patent Publication No. 2003-003042, a lipstick composition is disclosed, which is composed of bentonite or laponite 2% to 10% by weight, ethanol 0.5% to 5% by weight, and the remaining amount of volatile oil The gel matrix is long-wearing and can reduce the dryness of the lips.

Through this attempt, the following results have been obtained: Although to some extent it has overcome Lips feel dry, but the effects of high color rendering, uniform color rendering, endurance and adhesion required by high color rendering lipsticks are reduced. Therefore, it is difficult to realize a high-color-rendering lipstick with high color-rendering properties and no dryness.

Therefore, the inventors of the present invention select a specific composition in a manner that can simultaneously satisfy the opposite attributes of high color rendering and dryness, and formulate the specific composition according to a fixed content ratio, thereby preparing a lip cosmetic composition that can simultaneously ensure the above effects .

Therefore, the object of the present invention is to provide a lip cosmetic composition, which has high color rendering and uniform color rendering power, lasting power and soft use feeling, and at the same time, there is no dry feeling or color jam on the lips as time passes. Phenomenon.

In order to achieve the above-mentioned object, the present invention provides a lip cosmetic composition, which includes wax, oil, pigment and powder, and the composition includes a silicone gel and a slurry compound.

Preferably, the above-mentioned lip cosmetic composition includes the above-mentioned silicone gel and the slurry compound in a weight ratio of 1:4 to 4:1.

At this time, the above-mentioned silicone rubber includes selected from polydimethylsiloxane/vinyl poly One of the group consisting of methylsiloxane cross-linked polymer, acrylate/stearyl acrylate/polydimethylsiloxane/methacrylate copolymer and combinations thereof.

And, the above-mentioned slurry compound includes selected from hydrogenated castor oil isostearate, bis-diglycerol polyglyceryl adipate-2, hydrogenated polystyrene, ethylene/propylene/styrene copolymer, butene/ Ethylene/styrene copolymer, oleic acid/linoleic acid/linolenic acid polyglyceride, paraffin oil, mineral oil, caprylic acid/capric triglyceride, hydrogenated styrene/isoprene copolymer, bis-hydroxylauryl Polydimethylsiloxane/isophorone diisocyanate (Isphoronethe Diisocyanate, IPDI) copolymer, plant sterol/isostearyl alcohol/cetyl alcohol/stearyl alcohol/behenyl dimer linoleate and One of the ethnic groups formed by its combination.

In particular, in the overall composition, 3% by weight or less of powder is used.

The lip cosmetic composition of the present invention has the following advantages: a high color rendering color is uniformly presented to the entire lip, and the color rendering power is maintained for a long time due to excellent adhesion.

In particular, the above-mentioned composition has excellent moisturizing power, so that it can improve the dryness, cutin, floating phenomenon, jamming phenomenon, etc. of the previous high color lip cosmetic composition over time at the source, so as to always express Gives a moisturizing look.

Figure 1 shows (a) Example 1, (b) Comparative Example 1, (c) of the present invention Photographs of the spreadability of the lipsticks prepared in Comparative Example 2, (d) Comparative Example 3, and (e) Comparative Example 4.

In the lip cosmetic composition, the powder added in order to obtain the advantages of high color rendering, uniform color rendering and durability, etc. has the following disadvantages: reduced elongation; after being applied to the lips, the cosmetic composition coagulates Card color to lip wrinkles; induce dryness and keratin. A matte lipstick with high color rendering shows both advantages and disadvantages. However, in the present invention, a lip cosmetic composition is proposed, which can exhibit the advantages of high color rendering, uniform color rendering power and durability as it is, improve extensibility, and prevent color jams after being applied to the lips. Disadvantages related to dryness.

Specifically, the lip cosmetic composition of the present invention adds a gel formulation that has adhesive force by using silicone gel and a slurry compound in an optimal combination, instead of reducing the content of powder that causes the above-mentioned problems. Therefore, even if the content of powder is reduced, high color rendering and uniform color rendering can be achieved, and the problems of color blocking, dry lips, reduced keratin and ductility caused by powder can be improved.

Silicone imparts a smoothness to the lip cosmetic composition, softly fills out lip wrinkles and achieves a plump look. In addition, it plays the role of forming a soft film to effectively fix the pigment (i.e., pigment) and powder, and improving adhesion and endurance after being applied to the lips.

The slurry compound is used for moisture retention and ductility. It is a substance that exhibits an anisotropic crystalline arrangement in a solid state and occurs at a specific temperature. Reversible changes in the properties of solids and liquids. The melting point of this substance is as low as 10°C to 40°C, so it exists as a soft paste at room temperature, so that even if time passes, it will not change over time and maintain a soft feeling of use.

When the above-mentioned silicone gel and the slurry compound are mixed, a composition of a gel formulation having adhesive force is obtained. The composition of the above-mentioned gel formulation is mixed with other components (for example, wax, oil, pigment, etc.) to prepare a lip cosmetic composition. The composition of the above-mentioned gel form with adhesive force improves durability due to its high adhesion to the lips, and achieves uniform color presentation on the whole due to the uniform dispersion of pigments, and exhibits soft extensibility. In particular, when there are irregularities on the lips due to keratin, lip wrinkles, etc., the adhesive gel formulation fills in the irregularities and presents colors, so that a smooth makeup can be achieved on the entire lips.

Preferably, the above-mentioned gel formulation with adhesive force is mixed with silicone rubber in a weight ratio of 1:4 to 4:1, preferably 1.2:1 to 3:1, and most preferably 1.5:1. Slurry compound is used. In the case where the content of the silicone gel is too high, the color blocking phenomenon or the coagulation phenomenon of the cosmetic composition jamming into the lip lines after being applied to the lips is improved, but the adhesion strength is reduced, which causes the problem that it is difficult to display the color for a long time. In addition, when the above-mentioned slurry compound is used excessively, the moisturizing properties become good and the moisturizing feeling is achieved without the generation of keratin, but the color peels off and condenses and it becomes difficult to achieve uniform color rendering on the entire lip, so it is preferably It is mixed and used suitably within the above-mentioned range.

In addition, in order to further improve the desired effect of the present invention, the mixing ratio of the above-mentioned silicone rubber and the slurry compound is adjusted, and at the same time, each composition is controlled in the overall composition. Content.

Preferably, in 100% by weight of the lip cosmetic composition, 10% by weight to 50% by weight, preferably 20% by weight to 40% by weight of the aforementioned silicone gel is used. If the content of the above silicone gel is less than the above range, there will be dry stretchability, causing the cosmetic composition to condense to the lip keratin or lip wrinkles, and the overall uniform color rendering power becomes insufficient. On the contrary, If it exceeds the above range, there is a problem of decreased adhesion and durability, so it is appropriately used within the above range.

In addition, in 100% by weight of the lip cosmetic composition, 5% to 40% by weight, preferably 10% to 30% by weight of the above-mentioned slurry compound is used. If the content of the above-mentioned slurry compound is less than the above-mentioned range, the skin stretchability will be deteriorated or the dryness will be increased. On the contrary, if it exceeds the above-mentioned range, the color will fall off and condense and become insufficient to achieve uniformity over the entire lip. And because of the problem of smooth color rendering, use it appropriately within the above range.

At this time, in the present invention, the types of silicone and slurry compounds used are not particularly limited, and any of them may be used as long as they are common users in the field of cosmetic raw materials.

As a representative of the above-mentioned silicone rubber, it can be selected from polydimethylsiloxane/vinyl polydimethylsiloxane cross-linked polymer, acrylate/stearyl acrylate/polydimethylsiloxane/methicone Acrylate copolymer and its combination constitute one of the groups.

In addition, the above-mentioned slurry compound may be a rosin-based slurry, preferably hydrogenated castor oil isostearate, bis-diglyceride fatty acid adipate-2, hydrogenated polystyrene Ethylene, ethylene/propylene/styrene copolymer, butene/ethylene/styrene copolymer, oleic acid/linoleic acid/linolenic acid polyglyceride, paraffin oil, mineral oil, caprylic/capric triglyceride, hydrogenated benzene Ethylene/isoprene copolymer, bis-hydroxylauryl polydimethylsiloxane/IPDI copolymer, plant sterol/isostearyl alcohol/cetyl alcohol/stearyl alcohol/behenyl alcohol dimer linoleum As one of the group consisting of acid esters and combinations thereof, it is preferable to use bis-diglycerol polyadipate-2 and oleic acid/linoleic acid/linolenic acid polyglyceride.

The lip cosmetic composition whose blending ratio of silicone gel and slurry compound is adjusted as described above can be prepared into various formulations, has soft stretchability, and can also achieve a clear appearance on dry lips, especially the parts that produce keratin. It can also fill in lip wrinkles and achieve a smooth and plump makeup.

In particular, compared with the previous lip cosmetic composition using a powder content of 10% by weight or more, the lip cosmetic composition of the present invention can achieve high color rendering even if it uses a powder of 3% by weight or less, and Excellent adhesion and durability. In addition, it does not produce dry lips, cuticles, floating phenomenon, and color blocking that occur when high content of powder is used to achieve a matte texture, so that it can always present a moisturizing makeup look.

The usable powder is not particularly limited in the present invention, and it may be any material as long as it is a material known in the technical field.

As a representative powder composition, inorganic powders such as muscovite, synthetic mica, sericite, titanium dioxide, titanium dioxide-coated mica, aluminum oxide, iron oxide yellow, iron oxide black, carbon black, barium sulfate, silicon oxide, and zeolite can be used; And nylon, polymethyl methacrylate (PMMA), polystyrene, polyethylene and cellulose and other organic Powder; these can be used separately or mixed.

At this time, the above-mentioned powder may be spherical, plate-shaped, or needle-shaped, and it is preferable to use spherical particles of 1 μm to 100 μm. Preferably, in the embodiment of the present invention, spherical alumina and nylon are mixed and used as the powder.

At this time, in the overall lip cosmetic composition, 3% by weight or less of the above-mentioned powder is used, preferably in the range of 0.5% by weight to 3% by weight. If the content of the powder is less than the above range, the color rendering power, durability, and adhesion of the product will be insufficient. On the contrary, if it exceeds the above range, dryness and keratin will be induced, so use within the above range as appropriate.

The lip cosmetic composition of the present invention can be used together with the above-mentioned composition in waxes, oils, pigments, and other additives used in ordinary lip cosmetic compositions.

The waxes used in the present invention include all waxes such as hydrocarbon waxes, vegetable waxes, and silicone waxes that are generally used in lip cosmetics. Specifically, solid phase wax is preferred, and examples include microcrystalline wax, ozokerite wax, beeswax, candelilla wax, mineral wax, carnauba wax, rice bran wax, paraffin wax, montan wax, wood wax, and cocoa wax.

In a preferred embodiment of the present invention, polyethylene wax and ozokerite wax are mixed for use.

This wax plays the role of imparting a feeling of use to the product, moisturizing and maintaining a fixed hardness. In 100% by weight of the overall lip cosmetic composition, the content of wax is preferably in the range of 3% by weight to 30% by weight. When the content of the above wax is less than the above range, it is difficult to maintain a fixed hardness. On the contrary, when the content exceeds the above range, it is difficult to maintain a fixed hardness. It will result in a dry feeling in use of the final lip cosmetic composition, a decrease in extensibility, or a non-smooth surface.

The oil used in the present invention includes ester oils, hydrocarbon oils, natural oils, and mixtures thereof that are generally used in lip cosmetics. Specifically, mineral oils such as liquid paraffin; animal oils such as squalene and hydrogenated squalene; vegetable oils such as palm oil, avocado oil, jojoba oil, sesame oil, olive oil, and castor oil can be used ; Butyl myristate, isopropyl myristate, cetyl myristate, isopropyl palmitate, butyl stearate, polybutene, polyisobutene, hydrogenated polyisobutene, various polyols, 2- Synthetic oils such as ethyl hexanoic acid triglyceride, triglyceride oil, myristyl lactate, octyldodecanol, dioctyl carbonate, and diisostearyl malate; but not limited to these . In a preferred embodiment of the present invention, diisostearyl malate and dioctyl carbonate are mixed for use.

Such oil is used to impart a feeling of use and moisturizing to the product, and to achieve uniform mixing with other compositions, and is preferably in the range of 40% to 80% by weight in 100% by weight of the overall lip cosmetic composition. If the content of the oil is less than the above range, the above-mentioned effect cannot be ensured. On the contrary, when it exceeds the above range, it is difficult to form a dosage form, so it is appropriately used within the above range.

Hereinafter, the preparation method of the lip cosmetic composition of the present invention will be described in more detail based on the examples of the present invention. Of course, the present invention is not limited to these embodiments.

<Example 1 to Example 5, and Comparative Example 1 to Comparative Example 4> Preparation of lip cosmetic composition

The raw materials of the following Table 1 were weighed, heated and dissolved at 85°C, and then stirred with a homogenizer to prepare a mixture. After deaerating the obtained mixture, it was cooled at -20°C to prepare a lipstick-type lip cosmetic composition.

<Test Example 1> Evaluation of ductility

In order to confirm the color blocking phenomenon of the lipsticks prepared in the above-mentioned Example 1 and Comparative Examples 1 to 4, the artificial leather was reciprocated twice with the same force. The photograph of the artificial leather is shown in FIG. 1.

Referring to FIG. 1, it was confirmed that in the case of the lipstick of Example 1 that includes both silicone gel and a slurry compound according to the present invention, it was uniformly applied to artificial leather, so that it can be seen that there is no jam and the color is uniform. Specifically, it can be seen that in the case of the lipstick of Example 1, the gel formulation with adhesive force can fill up the unevenness on one side, and infiltrate (i.e., penetrate) on the other side to achieve color rendering, instead of the previous color produced by powder The state of covering (i.e., floating) on the lips.

In contrast, in the case of the lipsticks of Comparative Examples 1 to 4, voids are generated and the colors are unevenly distributed. Even if the same pigment is used in the same content, the color rendering power and color rendering power are different.

<Test Example 2> Sensory Evaluation

The extensibility, color rendering power, color rendering power, color staying power, dryness, etc. of the lip cosmetic composition prepared in the above-mentioned Examples and Comparative Examples were evaluated.

The subjects of the assessment are unmarried and married women aged 24 to 35. Ten female professional inspectors with at least 2 years of makeup experience and at least continuous use of lip products for at least 5 times a week will be assigned 5 points according to each item (1 Points: very poor, 3 points: normal, 5 points: very good) for comparative evaluation. At this time, when all the numerical values are 3 points or more, it can be manufactured, and the results are shown in Table 2 below.

According to Table 2 above, it can be seen that in the case of the lipstick of Example 1 of the present invention, the color durability and color rendering power are excellent, and the feeling of use is also better. In particular, there is no dry feeling after 6 hours, and there is almost no seizing phenomenon, so it can be seen that it is not only moisturized, uniform, but also has soft stretchability.

Specifically, the lipstick of Comparative Example 1 used powder with the same content as that of Example 1, and did not use silicone and slurry compounds, resulting in serious jamming. As a result, the color rendering power and color staying power are very poor.

Comparative Example 2 only uses silicone, and although it improves color rendering power, endurance, and ductility to some extent, as shown in Fig. 1, the result is insufficient to achieve uniform color rendering power as a whole.

The lipstick of Comparative Example 3 was a case where only the slurry compound was used, and it was confirmed that the moisturizing power was improved to some extent and there was no dry feeling after 6 hours, but the color jam phenomenon occurred and the color development power was low.

In addition, the lipstick of Comparative Example 4 is free of silicone and paste compounds and uses more than 10% by weight of powder as in the prior art. After 6 hours, a serious dry feeling is generated, which is in the overall color blocking phenomenon, staying power, and ductility. The evaluation showed very low values.

Based on these results, it can be seen that the lip cosmetic composition of the present invention can achieve high color rendering power by using silicone and slurry compounds even if the powder content is reduced, and at the same time can improve the dryness.
