Description

Lip cosmetic composition

The present invention relates to a lip cosmetic composition having high coloration without a khaki phenomenon and a dry feeling.

Lipsticks are usually oily, including waxes, oils, pigments and powders. The wax retains the appearance of a lipstick, the oil imparts a luxurious feeling of use and gloss, the pigment exhibits a color sensation as a pigment and/or a dye, and the powder is used for improving the ductility, adhesion, and durability, and is also used for achieving a matte texture.

Following the changes in the times, the trend of make-up has also changed. Until the 1990s, lipsticks with matte and opaque makeup were mainly used, but after 2000, the transparency and moisturization of lip gloss or lip gloss were emphasized. The above-mentioned lip gloss or lip gloss has the advantage of being light and thin to use, but has the problem that the color has a long-lasting force and a weak adhesive force and is easy to remove makeup.

Recently, in addition to the lipstick prepared by wax, various types of lipsticks such as lip crayon, lip marker, lip glaze, lip grease, lip gloss oil, and lip pencil have been popular, and

A highly colored lipstick with a distinct color is favored.

High-color lipstick is a lipstick that is kept in color to the lips for a long time and has a vivid color. The above adhesion and durability are related to the powder in the composition constituting the lipstick.

As described above, the powder is related to the ductility of the lipstick, that is, the degree of easy application, and generally, if the spherical powder is large, the lipstick has a gentle ductility. Also, the higher the content of the powder, the higher the adhesion of the lipstick to the lip.

High color-developing lipstick achieves high color rendering power and color endurance by using an excess amount of powder of 10% by weight or more, has a dry and dull matt feeling, and has a soft makeup feeling. However, the high coloring lipstick has no oil, so the following problems occur: the stretching is relatively dry, the color is unevenly applied, and the dry feeling and the keratin are induced over time to cause the lips to be cracked and dried, due to color floating or coloring. Make horny or wrinkles stand out.

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

In Korean Patent Publication No. 2001-0110563, a perfluoroethylalkylpolydimethyloxane, an alkyl polydimethyloxane, a plant polysaccharide, and a platy powder are proposed to prevent lip. A lip cosmetic composition that is dry and gives moisture and shine.

Further, in Korean Laid-Open Patent Publication No. 2003-003042, a lipstick composition comprising 2% by weight to 10% by weight of bentonite or laponite, 0.5% by weight to 5% by weight of ethanol, and the remaining amount of volatile oil is disclosed. The gel matrix is long-wearing and reduces the drying of the lips.

With such an attempt, the following results were obtained: although the dry feeling of the lip was overcome to some extent, the high color rendering, uniform color rendering power, durability, and adhesion required by the high coloring lipstick were instead decline. Therefore, it is difficult to achieve a high coloration lipstick having high color development characteristics and no dry feeling. [Previous Technical Literature]

[Question to be solved by the invention]

Therefore, the inventors of the present invention select a specific composition in such a manner that the opposite properties of high color development and dryness can be simultaneously satisfied, and the above specific composition is formulated in a fixed content ratio, thereby preparing a lip cosmetic composition which can simultaneously ensure the above effects. .

Accordingly, it is an object of the present invention to provide a lip cosmetic composition which has high color development and uniform color rendering power, endurance and soft feeling of use, and has no dry feeling or coloration of the lips over time. phenomenon.

[Means for solving the problem]

In order to achieve the above object, the present invention provides a lip cosmetic composition comprising a wax, an oil, a pigment and a powder, the composition comprising a silicone and a slurry compound.

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

At this time, the above-mentioned silicone rubber comprises a crosslinked polymer selected from polydimethylsiloxane/polydimethylsiloxane/vinyl polydimethyloxane, acrylate/stearyl acrylate/polydimethyl acrylate. One of the groups of oxirane/methacrylate copolymers and combinations thereof.

Further, the above slurry compound is selected from the group consisting of hydrogenated castor oil isostearate, bis-diglyceryl polylipidate adipate-2, hydrogenated polystyrene, ethylene/propylene/styrene copolymer, butene/ Ethylene/styrene copolymer, oleic acid/linoleic acid/linolenic acid polyglycerol ester, paraffin oil, mineral oil, caprylic/capric triglyceride, hydrogenated styrene/isoprene copolymer, bis-hydroxylauryl Isophorone the Diisocyanate (IPDI) copolymer, phytosterol/isostearyl alcohol/cetyl alcohol/stearyl alcohol/behenyl dimer linoleate and One of the groups formed by the combination.

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

[Effects of the Invention]

The lip cosmetic composition of the present invention has an advantage that a color of high color development is uniformly presented to the entire lip portion, and color rendering ability is maintained for a long time due to excellent adhesion.

In particular, the above composition is excellent in moisturizing power, so that the dry feeling, keratin, floating phenomenon, and coloring phenomenon of the previously high-color lip cosmetic composition can be improved at the source to always perform. A moisturizing look.

In the lip cosmetic composition, the powder added in order to obtain high color rendering, uniform color rendering power and durability has the following disadvantages: reduced ductility; after application to the lip, cosmetic composition condensation occurs. Card color to the wrinkles of the lips; induces dryness and keratin. The high-color matte lipstick exhibits both of the above advantages and disadvantages. However, in the present invention, a lip cosmetic composition is proposed which exhibits the advantages of high color development, uniform color rendering power and durability as described above, and improves the ductility, and does not cause coloration after application to the lips. Disadvantages associated with dryness.

Specifically, the lip cosmetic composition of the present invention is added with a gel formulation having an adhesive force by using a silicone resin and a slurry compound in an optimum combination, instead of reducing the content of the powder causing the above-mentioned problems, Therefore, even if the content of the powder is reduced, high color development and uniform color rendering power can be achieved, and problems such as the coloring phenomenon caused by the powder, the dryness of the lips, the deterioration of the keratin and the stretchability can be improved.

Silicone imparts a smooth feel to the lip cosmetic composition, gently filling the lip lines for a plump look. Further, it exhibits the following effects: a soft film is formed to effectively fix the pigment (i.e., pigment) and the powder, and after application to the lip, the adhesion and the endurance are improved.

The slurry compound is used for moisturizing and ductility, and exhibits an anisotropic crystal arrangement in a solid state, and a reversible change in properties of solids and liquids occurs at a specific temperature. Since the melting point of such a substance is as low as 10 ° C to 40 ° C, it is also present in a soft slurry at normal temperature, so that it does not change over time to maintain a soft feeling of use even after passage of time.

When the above-mentioned silicone resin and the slurry compound are mixed, a composition of a gel formulation having an adhesive force is obtained, and the composition of the gel formulation is mixed with other components (for example, wax, oil, pigment, etc.) to prepare a lip cosmetic composition. The composition of the gel form having the adhesiveness is improved in durability due to the high adhesion to the lips, and the uniform color distribution of the pigments can achieve uniform color expression as a whole, exhibiting gentle ductility. In particular, when the lip portion has irregularities due to keratinization, lip wrinkles, or the like, the gelling agent having an adhesive force fills the unevenness and presents a color, so that a smooth makeup can be achieved on the entire lip portion.

Preferably, the above gel dosage form having adhesion is mixed with a silicone resin at a weight ratio of 1:4 to 4:1, preferably a weight ratio of 1.2:1 to 3:1, and most preferably a weight ratio of 1.5:1. It is used as a slurry compound. When the content of the above-mentioned silicone rubber is too large, the coloring phenomenon or the condensation phenomenon in which the cosmetic composition is stuck to the lip after application to the lip is improved, but the adhesion is lowered to cause a problem that it is difficult to permanently exhibit color. Further, when the above-mentioned slurry compound is used excessively, the moisturizing property is improved to achieve a moisturizing feeling without causing keratin, but the color is detached and condensed, and it becomes difficult to achieve uniform color rendering power in the entire lip portion. They are suitably mixed and used within the above range.

Further, in order to further enhance the effect desired by the present invention, the blending ratio of the above-mentioned silicone and the slurry compound is adjusted, and the content of each component is controlled in the entire composition.

It is preferable to use 10% by weight to 50% by weight, preferably 20% by weight to 40% by weight, based on 100% by weight of the lip cosmetic composition, of the above-mentioned silicone rubber. When the content of the above-mentioned silicone is less than the above range, there is a problem that the dryness of the cognac is caused, and the cosmetic composition is condensed to the lip horniness or the wrinkles of the lips, and the uniform color rendering power becomes insufficient as a whole. When it exceeds the above range, there is a problem that the adhesion and the durability are lowered, and therefore it is suitably used within the above range.

Further, the above slurry compound is used in an amount of from 5% by weight to 40% by weight, preferably from 10% by weight to 30% by weight, based on 100% by weight of the lip cosmetic composition. When the content of the above-mentioned slurry compound is less than the above range, there is a problem that the skin stretchability is deteriorated or the dry feeling is increased. On the contrary, if it exceeds the above range, the color is condensed and becomes insufficient to make the entire lip uniform. The smooth color exhibits a problem of force, and thus is suitably used within the above range.

In this case, the type of the silicone resin and the slurry compound to be used in the present invention is not particularly limited, and may be any one as long as it is usually used in the field of cosmetic raw materials.

As a representative of the above silicone, it may be selected from polydimethylsiloxane/polydimethyloxane/vinyl polydimethyloxane crosslinked polymer, acrylate/stearyl acrylate/poly One of the groups consisting of dimethyloxane/methacrylate copolymers and combinations thereof.

Further, the above slurry compound may be a rosin-based slurry, preferably hydrogenated castor oil isostearate, bis-diglyceryl polylipidate adipate-2, hydrogenated polystyrene, ethylene/propylene. /styrene copolymer, butene/ethylene/styrene copolymer, oleic acid/linoleic acid/linolenic acid polyglycerol ester, paraffin oil, mineral oil, caprylic/capric triglyceride, hydrogenated styrene/isoprene Ene copolymer, bis-hydroxylauryl polydimethyloxane/IPDI copolymer, phytosterol/isostearyl alcohol/cetyl alcohol/stearyl alcohol/behenyl dimer linoleate and combinations thereof One of the constituent groups is preferably bis-diglyceryl polylipidate adipate-2 and oleic acid/linoleic acid/linolenic acid polyglycerol.

The lip cosmetic composition having the adjusted ratio of the silicone rubber to the slurry compound as described above can be prepared into various dosage forms, and has mild ductility, and can be vividly displayed on the dry lip, particularly the horny portion. Color, and can also fill the lip lines to achieve a smooth and full makeup.

In particular, the lip cosmetic composition of the present invention can achieve a high color rendering color even when a powder of 3% by weight or less is used, compared to a lip cosmetic composition which previously uses a powder content of 10% by weight or more. Excellent adhesion and durability. Further, it does not occur in the dry feeling of the lips, the horniness, the floating phenomenon, and the coloring phenomenon which are generated when a high content of the powder is used in order to realize the matte texture, so that the moisturizing feeling can always be exhibited.

The powder which can be used is not particularly limited in the present invention, and may be any material as long as it is known in the art.

As a representative powder composition, inorganic powders such as muscovite, synthetic mica, sericite, titania, titania-coated mica, alumina, iron oxide yellow, iron oxide black, carbon black, barium sulfate, cerium oxide, and zeolite can be used; And organic powders such as nylon, polymethyl methacrylate (PMMA), polystyrene, polyethylene, and cellulose; these may be used alone or in combination.
