Description

High Moisturizing Long Lasting Lipstick Composition

[Industrial use]

The present invention relates to a highly moisturizing sustaining lipstick composition, and more particularly, to a lipstick composition having excellent color sustainability and simultaneously having a high moisturizing effect.

[Prior art]

Lipstick is used to express various colors on the lips, and mainly consists of colorants and oily ingredients. Colorants may be added to colorless lipsticks, lip glosses, etc., because they are intended to exhibit various colors on the lips, and castor oil may be used as color pigments, dye dyes, and dye solubilizers. In addition, the oil phase component is intended to form a stick shape, to impart viscosity to the molded lipstick and to dissolve the pigment component, and has waxes such as candelilla wax and ceresin, which are solid at room temperature, and a melting point close to liquid or body temperature at room temperature. Lanolin, castor oil, hydrocarbon oils and fatty acid ester oils and the like are used.

The biggest disadvantage of such lipstick is that it is easily erased. Also, since the lips have almost no stratum corneum, unlike normal skin, moisture loss on the surface of the lips is very easy, and the lips are easily dried and open.

Accordingly, recently, studies on lipsticks having excellent color persistence and moisturizing effect have been conducted. European Patent Publication No. 94-602905 proposes a persistent cosmetic composition which uses a large amount of a volatile solvent and a silicone resin, in addition to containing a wax, an oil and a pigment component. Compared to regular lipsticks, this composition has improved the persistence aspects such as bleeding, but it mainly uses volatile solvents, silicone resins and waxes, and pigments. This was accompanied by a drawback of drying out.

Japanese Patent Application Laid-Open No. 94-287109 proposes a composition for oily lips in which the dyeing property of the lipstick containing the tar pigment is improved to enhance the persistence of the color. However, this composition compensates for the drawbacks of ordinary lipsticks by using the same oily base as regular lipsticks, since the lipsticks are easily smeared on cups, clothes, etc. after using the lipsticks, and thus the sustaining effect of the lipsticks is remarkably inferior. To be greatly lacking. In addition, Japanese Patent Application Laid-Open No. 61-83110 uses phytosterols, cholesterol, phospholipids and dispersants such as cations, anions, nonionics and amphoteric surfactants to improve the moisturizing properties of lipsticks. A composition has been proposed that emulsifies water to impart a moisturizing effect to the lips. However, this method has a problem with storage safety. In addition, since the inventions for improving the moisturizing properties have an oily composition almost similar to that of ordinary lipsticks, they have a disadvantage of being easily buried and erased in the same way as conventional ordinary lipsticks.

US Pat. No. 5,085,856 proposes a lipstick composition in which water is stabilized using a phospholipid such as lecithin and an emulsifier such as glycerin monostearic acid as a coupling agent as an auxiliary emulsifier. In addition, International Patent Publication No. WO 94/6401 attempts to stabilize a large amount of a moisturizer to a lipstick by using a coupling agent of an oil and a moisturizer such as glyceryl oleate / propylene glycol (1: 1) and glyceryl monostearate. International Patent Publication No. WO 94/6400 attempts to stabilize moisturizers with surfactants and lecithins having kraft points below room temperature, such as sorbitan oleate and sorbitan sesquioleate. However, there is a possibility of causing some irritation to the skin of the lips having an extremely thin keratin structure by the surfactant and the coupling agent such as glycerin monostearic acid used in the above methods.

The present invention is to solve the above problems, an object of the present invention is to provide a high moisturizing sustaining lipstick composition excellent in moisturizing effect.

Another object of the present invention is to provide a highly moisturizing sustained lipstick composition having excellent safety that does not irritate the lips by stabilizing the moisturizer using a non-irritating compound.

Still another object of the present invention is to provide a highly moisturizing sustaining lipstick composition having excellent color persistence that makeup does not stick well.

[Means for solving the problem]

In order to achieve the above object, the present invention is 0.1 to 50 parts by weight of a highly moisturizing complex comprising purified water, galactosyl ceramide, cholesterol, polyhydric alcohol and liquid oil; And 0.1 to 60 parts by weight of volatile oil.

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

The lipstick composition of the present invention contains a galactosyl ceramide and cholesterol having a structure similar to a keratin component having a moisture control function in the skin of the human body with a moisturizing agent and purified water which are extremely difficult to stabilize in a lipstick composition composed of volatile oils and waxes, which show durability. Lipstick composition is stabilized by forming a high moisturizing composite used.

Such a lipstick composition of the present invention is composed of 0.1 to 50 parts by weight of a highly moisturizing composite having a moisturizing effect and 0.1 to 60 parts by weight of a volatile oil having a color sustainability. The highly moisturizing complex includes 1 to 60 parts by weight of galactosyl ceramide, 0.1 to 50 parts by weight of cholesterol, 0.1 to 90 parts by weight of purified water, 0.1 to 60 parts by weight of a moisturizer and 0.1 to 50 parts by weight of liquid oil. The lipstick composition of the present invention may further include a colorant in an amount capable of exhibiting a desired color in order to exhibit color, and may further include a trace amount to 30 parts by weight of an oily component in order to have a stick shape. In addition, silicone resins such as trimethyl siloxy silicate can be used if necessary to improve the durability. In addition, a sunscreen, a discoloration inhibitor, a preservative, a fragrance and an oxidation stabilizer, etc. can be used further.

Galactosyl ceramide used in the highly moisturizing complex is a component having a structure similar to that of the keratin component having moisture control function of the human skin, and is great for stabilizing hydrophilic purified water and a moisturizer in a volatile oil base that imparts the sustainability of the present invention. Effect. In addition, when the lipstick of the present invention is applied to the lip surface, a soft lipid film is formed on the lip surface, thereby improving color persistence and additional moisturizing effect. The use amount is preferably 1 to 60 parts by weight in the high moisturizing composite, when the blending amount is less than 1 part by weight does not effectively stabilize the moisturizer in the lipstick, when the content exceeds 60 parts by weight the viscosity of the high moisturizing complex itself Is too high, and excessive bubbles are produced during manufacture, which is not good.

In addition, cholesterol has an effect of increasing the solubility of galactosyl ceramide in the high moisturizing complex, the amount of which is 0.1 to 50 parts by weight in the high moisturizing complex. When the amount of cholesterol is less than 0.1 part by weight, the effect of increasing the solubility of galactosyl ceramide is not sufficient, and when it exceeds 50 parts by weight, the viscosity of the highly moisturizing complex is too high, which is not good.

The humectant of the present invention consists of purified water and a polyhydric alcohol. The content of purified water is 0.1 to 90 parts by weight in the high moisturizing composite, when less than 0.1 parts by weight does not exhibit a sufficient moisturizing effect, when it exceeds 90 parts by weight it is difficult to stabilize the high moisturizing complex. As the polyhydric alcohol, glycerin, 1,3-butylene glycol, sorbitol, propylene glycol and the like can be used. The amount of the polyhydric alcohol is 0.1 to 90 parts by weight in the high moisturizing composite, when less than 0.1 parts by weight, it is difficult to expect a sufficient moisturizing effect, when it exceeds 90 parts by weight it is difficult to stabilize the high moisturizing complex.

In addition, the highly moisturizing complex of the present invention includes a liquid oil at room temperature to control the viscosity of the high moisturizing complex and serve as a solvent of the dye. As such an oil, 0.1-50 weight part of higher alcohols, such as a hydrocarbon oil, ester oil, or octyl dodecanol, can be used. When the amount of the oil is less than 0.1 part by weight, the viscosity control function of the high moisturizing composite is less, and at 50 parts by weight or more, it is difficult to stabilize the moisturizer.

The lipstick composition of the present invention can impart a moisturizing effect that could not be expected in normal and sustained lipsticks by using 0.1 to 50 parts by weight of a high moisturizing complex composed of the above components. When the highly moisturizing complex is used at less than 0.1 part by weight, the moisturizing effect is not sufficient, and when it exceeds 50 parts by weight, the stabilization and usability of the moisturizer and purified water may be inhibited.

In addition, volatile oils such as cyclic or chain silicone oils or isoparaffins are used to represent the persistence in the lipstick of the present invention. The volatile oils may exhibit satisfactory sustainability within the range of 0.1 to 60 parts by weight. The chain silicone oil used in the present invention is preferably a volatile low viscosity dimethylpolysiloxane having a viscosity of 0.65 to 1.5 centistokes, and the cyclic silicone oil may be a cyclomethicone (where n is 4 in Formula 1 below). It is appropriate to have a structure of. It is also preferable that isoparaffin has 10 to 20 carbon atoms. In the present invention, the above volatile oils may be used alone or in combination of two or more thereof.

[Formula 1]

(Where n is an integer of 3-6)

The lipstick of the present invention does not necessarily show a color, but a colorant may be further used to display the color. As the coloring agent, any of the coloring pigments used for producing lipsticks such as tar pigments, titanium dioxide, ferric oxide, iron sulfate, black oxide, or the like, or pearl pigments such as mica titanium and colored mica titanium, can be used. In addition, all oil components conventionally used such as lanulin, castor oil, etc. may be used to dissolve the colored pigment, and in order to increase solubility, stearic acid butyl ester, tetrahydropropyl alcohol and octyldodecanol as dissolution aids. Etc. can also be used further.

The oily component which can be added in the present invention is a liquid wax at room temperature that serves to dissolve dyes and solid waxes at room temperature, and inherent viscosity to the molded lipstick to have a stick shape conventionally used for lipstick. Alternatively, all dairy ingredients with melting points close to body temperature can be used. Representative examples of the waxes include beeswax, candelilla wax, natural waxes such as wood wax, hydrocarbon waxes such as solid paraffin, ceresin, and the like, and oil components having a melting point close to liquid or body temperature include cacao oil, castor oil, Natural substances such as lanolin, hydrocarbons such as waserine and liquid paraffin, fatty acid ester oils and glycerides. This oil phase component may be added at a trace amount to about 30 parts by weight.

Lipstick composition of the present invention composed of the above-mentioned composition is not used in conventional general lipsticks and persistent lipsticks extremely difficult to stabilize purified water and hydrophilic moisturizing polyhydric alcohol without using a surfactant that stimulates at all, galactolsil ceramide, cholesterol, moisturizer, etc. It is a lipstick composition that forms a highly moisturizing complex formed in a stable formulation and stably blends in a lipstick base exhibiting persistence, and at the same time combines sustainability and high moisturizing effects that were not expected in conventional lipsticks.

In order to prepare the lipstick composition of the present invention, 1 to 60 parts by weight of galactosyl ceramide, 0.1 to 50 parts by weight of cholesterol, 0.1 to 60 parts by weight of polyhydric alcohol and 0.1 to 50 parts by weight of liquid oil are mixed and the temperature is about 70 to 90. Increase to C and dissolve uniformly. The mixture is dispersed, cooled, and dispersed by adding 0.1 to 90 parts by weight of purified water to prepare a highly moisturizing composite. 0.1-50 parts by weight of the prepared highly moisturizing composite and 0.1-60 parts by weight of the volatile oil are mixed and the temperature is increased to about 70-90 ° C. to dissolve uniformly. Colorants and oily ingredients may be further added. Trimethylsiloxysilicate, preservative, etc. may be further added to this mixture. After dispersing this mixture, the resulting bubbles are defoamed to prepare a lipstick composition. In the said process, after performing a defoaming process, you may add a fragrance further.
