Description

Oil-drop makeup cosmetic composition}

The present invention relates to a cosmetic composition for makeup, and more specifically, it contains a water-soluble pigment capable of producing a coloring effect on the water phase, and an oil-drop that allows a large amount of oil droplets to be evenly and stably dispersed within the water phase. It relates to a makeup cosmetic composition.

In general, the makeup cosmetic composition may be divided into a water dispersion type, an oil dispersion type, or an emulsification type in which a water phase and an oil phase are mixed. Among them, there are water dispersion type and emulsifying type products that can use water-soluble pigments that produce a coloring effect.

However, the water dispersion type has the advantages of coloring persistence and light feeling, but it has a drawback of drying after application, and the emulsifying type having a moisturizing persistence has a drawback of being heavy and thick because an emulsifier must be used. Accordingly, cosmetics that separate the oil phase and the water phase are attracting attention.

An example of a cosmetic in which the oil phase and the water phase are separated as described above is a two-layer separation type cosmetic. The two-layer separable cosmetic has a unique characteristic in appearance, and is characterized in that the oil phase is dispersed by shaking. After use, the two-layer separating cosmetic is separated into an oil phase and an aqueous phase to form a layer again.

However, the two-layer separable cosmetic has a slippery and frustrating problem due to the oily portion. In addition, it lacked aesthetics, and had to be shaken several times during use, so it had inconvenience in use.

However, in the conventional cosmetic product in which oil droplets are dispersed in the water phase, the pigment cannot be contained in a large amount due to the problem that the viscosity of the thickener is destroyed by the pigment. Due to this, a small amount of the pigment may simply be contained for an aesthetic effect in appearance, but when a large amount of the pigment is added for the purpose of imparting color to the application site, the viscosity is broken.

Accordingly, the cosmetic in which the oil droplets are dispersed in the conventional water phase is inappropriate for the purpose of imparting color, and an oil-drop capable of holding more oily spherical particles without losing its viscosity even if it contains a large amount of pigment. The need for makeup cosmetic compositions has grown.

In the drawings, similar reference numerals refer to the same or similar functions throughout several aspects.

The terminology used in the present invention has been selected, while considering the functions in the present invention, general terms that are currently widely used have been selected, but this may vary according to the intention or precedent of a person skilled in the art or the appearance of new technologies. In addition, in certain cases, some terms are arbitrarily selected by the applicant, and in this case, their meanings will be described in detail in the description of the applicable invention. Therefore, the term used in the present invention should be defined based on the meaning of the term and the entire contents of the present invention, not a simple term name.

In the present invention, when a certain part “includes” a certain component, this means that other components may be further included instead of excluding other components, unless otherwise stated.

Hereinafter, the present invention will be described in detail.

The present invention,

The water phase contains purified water, moisturizing agent, chelating agent, thickener, cation supplying agent (electrolyte), water-soluble pigment,

Oil-drop make-up characterized in that the oily part includes any one or more oils selected from the group consisting of ester oils, hydrocarbon oils, silicone oils, and vegetable oils, and the oil is dispersed in the water phase in a spherical shape. Provided is a cosmetic composition.

The purified water refers to water purified by distilling constant water or through ion exchange resin. Well or tap water contains impurities such as dissolved inorganic matter, dissolved organic matter, particulates, and microorganisms, and thus cannot be used as it is. Common methods for purifying the purified water are distillation and ion exchange, but in addition, reverse osmosis using a reverse osmosis membrane. Adsorption method using powdered activated carbon. Filtration using a membrane filter. There are vibrated by argon or nitrogen, and degassing by boil, and purified water in the present invention can be manufactured according to the intention or precedent of a person skilled in the art or the appearance of a new technology. Purified water prepared through is referred to.

The moisturizer is intended to replenish moisture on the application site, and any water-soluble component containing polyol can be used. Specific examples include glycerin, and the present invention is not limited thereto, and any water-soluble component containing polyol may be used according to the intention or precedent of a person skilled in the art or the appearance of new technologies.

The chelating agent is also called EDTA, and is used for analytical chemistry such as analysis of metal ions, separation, removal, trace metal ion, softening of water, separation of rare earth elements, removal of kidney stones, prevention of oxidation of vitamin C, food Its use is very wide, such as prevention of deterioration by metals, cleaning agents, and precipitation inhibitors for heavy metal ions. Solubility in water is 0.2 g dissolved in 100 ml of water at 22 degrees. It is a colorless crystalline powder that has characteristics of making almost all metals and water-soluble chelates, and has been widely developed as an application of analytical chemistry. With regard to cosmetics, it plays a role in removing metal ions that may occur in cosmetics.

The thickener refers to a substance that serves to increase the viscosity of the cosmetic, and in the present invention, the thickener includes gellan gum and xanthan gum.

The gellan gum is a new hydrocolloid recently developed by CP Kelco, and is a next-generation gum in which usage is rapidly increasing due to the development of new uses in various countries such as the United States, Japan, and Europe. Gellan gum was first discovered in 1978 and is a high molecular polysaccharide obtained by fermenting carbohydrates in pure culture using Pseudomonas elodea. Gellan gum is composed of a ratio of 2:1:1 to glucose:glucuronic acid:rhamnose, and has a basic structure in which four sugar units are repeatedly connected in a straight line. Two acyl groups acetate and glycerate are present, two acyl groups are attached to one glucose group, and one glycerate per unit and one acetate per two units are repeated on average. In the low acyl gellan gum, the acyl group is completely removed, and the physical properties of the gel vary depending on the presence or absence of the acyl group. High acyl gellan gum makes soft, elastic, non-brittle gels, and low acyl gellan gum makes firm, non-elastic, brittle gels. In the present invention, it is appropriate to prepare a composition using low acyl gellan gum, but it is not limited. Gellan gum works with almost all cations, including hydrogen ions, to form a gel. Since the affinity of each cation is different, the divalent cations have chemical properties that have a much stronger affinity than the monovalent cations. In addition, gellan gum has a characteristic of forming a gel even at a low concentration, and it can make a gel like a flowing fluid, which gives excellent suspension ability. This has the advantage of being able to impart stability without promoting excessive thickener in various products.

The xanthan gum was developed as a food additive to increase the adhesiveness and viscosity of food, improve the emulsification stability, and improve the properties and feel of food. Therefore, it is used as a stabilizer, thickener, binder, emulsifier, solidifying agent, foaming agent and the like in food. Xanthan gum, a natural thickener, is purified, dried, and pulverized into isopropyl alcohol by polymer polysaccharide sample obtained by pure culture fermentation of carbohydrates using Xanthomonas Campestris, a causative agent of chlorophyll in cabbage. It is a mixture of sodium, potassium and calcium salts of north and glucuronic acid. Light yellow powder, neutral in aqueous solution. Xanthan gum is soluble in water and not ethanol. It has excellent heat resistance, and in particular, if there is citric acid, glacial acetic acid, the viscosity tends to decrease even when heated. Natural thickeners such as xanthan gum decrease in viscosity when acid or alkali substances coexist, but xanthan gum does not have a decrease in viscosity due to pH and is stable even within the range of pH 2-13. Xanthan gum has a good viscosity compared to other thickeners, and the viscosity gradually increases with concentration. It is a thickener that can be used in various products because it can significantly increase the viscosity even in a small amount.

The cation supplying agent (electrolyte) is to supply a cation to the composition, and may be introduced because a gel is formed only when the thickener has a cation. The cation supplying agent may use a compound containing any one or more cations of potassium, sodium, calcium, and magnesium. Specific examples include calcium lactate, and the present invention is not limited thereto, and any compound containing potassium, sodium, calcium, and magnesium cations according to the intention or precedent of a person skilled in the art or the appearance of new technologies Will be available.

The water-soluble pigment refers to a pigment that dissolves in water. Commercially available pigments or intentions or precedents of technicians working in the field, all kinds of water-soluble pigments according to the emergence of new technologies may be included in the present invention, and those of water-soluble pigments have no harmful effect on the human body. Unless they are all applicable.

In addition, the oil phase portion, distearyl malate, benzyl benzoate, butylene glycol dicaprylate / dicaprate, butyl isostearate, ethyl hexyl caprylate / ester oils containing caprate, hydrogenated, Hydrogenated AGE-60 Castor Oil, Hydrogenated Polyisobutene, Hydrocarbon Oils including Squalene, Jojoba Oil, Avocado Oil, Rose Hip Oil, Sunflower Oil, Rape Flower Oil, Vegetable Oil including Coconut Oil, Die It may include any one or more oils selected from the group consisting of silicone-based oils including phenyldimethicone, cyclophenylmethicone, dimethicone, and phenylpropyldimethylsiloxysilicate.

It is appropriate that the oil in the oil phase has a viscosity of 100cp to 20,000cp. The oil of the oily part of the present invention can maintain clear oil droplets even with a viscosity ranging from 100cp to 20,000cp by gellan gum and xanthan gum. In particular, the spherical shape can be maintained by gellan gum and xanthan gum even in oil having a low viscosity of 100 cp.

The viscosity of the oil can be measured using a spindle bar No. 4 at a rotation speed of a Brooklyn viscometer 20 rpm.

As the oil of the oil phase, a high refractive index oil having a refractive index of 1.5 or higher may be used. When using a high refractive index oil having a refractive index of 1.5 or higher, the shape of the oil drop is more clearly seen in appearance.

The refractive index of oil is an important factor that can increase the transparency of cosmetics. When oil is used as a high refractive index oil of 1.5 or more, transparency can be maintained even at a high oil content of 60% by weight. As can be seen in Figure 1 it can be seen that the shape of the seam and the coating member visible.

For example, diphenyldimethicone has a refractive index of 1.506, trimethyl pentaphenyl trisiloxane has a refractive index of 1.526, diphenylsiloxyl phenyl trimethicone has a refractive index of 1.526, phenylporophyldimethylsiloxysilicate has a refractive index of 1.5135, and propylene glycol dibenzoate has a 1.5375 , Methyl hydrogenated rosinate has a refractive index of 1.514, and if used properly with reference to this, it is possible to have a clearer oil drop shape.

The diphenyldimethicone may use KF-54HV or KF-54, and the trimethyl pentaphenyl trisiloxane and diphenylsiloxyl phenyl trimethicone may use BRB PB152, and the phenylporophyldimethylsiloxysilicate may be used. Shilshine 151 may be used, the propylene glycol dibenzoate may use LEXFEEL SHINE, and the methyl hydrogenated rosinate may use SN 265.

In one embodiment of the present invention, the process proceeds to use KF-54 to clearly observe the oil drop, but the present invention is not limited thereto, and one or more mixtures selected from the above oils are also used. It will be included in the scope of rights.

The thickener of the present invention is composed of gellan gum and xanthan gum, and can maintain transparency without losing its viscosity even with a large amount of pigment.

For example, in the case of a carbomer used as a thickening agent, the viscosity may be completely collapsed by a water-soluble pigment, and thus there is a problem that a pigment of a certain amount or more cannot be used. In the case of carbomer, it does not matter the amount of the pigment to the extent that it has an aesthetic effect by simply adding color to the cosmetic, but the viscosity of the pigment may collapse as much as it can be used as a color cosmetic for the purpose of imparting color to the skin. have.

In addition to carbomer, most of the thickeners have a problem in that the viscosity collapses due to the pigments described above.

Accordingly, the thickener of the present invention is composed of gellan gum and xanthan gum, and may have a characteristic that the viscosity does not collapse even with a large amount of pigment.

The water-soluble pigment of the present invention by the gellan gum and xanthan gum may be included 0.0001 to 5% by weight based on the total weight of the composition.

When the water-soluble dye is included in an amount of less than 0.0001% by weight, the amount of the dye contained in the composition of the present invention is too small, so that a problem of imparting color may be weak.

In addition, when the water-soluble pigment exceeds 5% by weight, the amount of the pigment is excessively large, and a problem may occur in that the viscosity is collapsed even when using gellan gum or xanthan gum.

The oily part of the oil-drop makeup cosmetic composition of the present invention may include 0.0001 to 60% by weight based on the total weight of the composition.

The oil phase portion is positioned in the shape of a ball inside the water phase portion, and as shown in FIGS. 2 to 6, the size of the oil droplet increases according to the oil content.

However, when the content of the oil phase increases, the transparency of the composition may be lowered, so an excessive amount of oil phase is not aesthetically appropriate.

Accordingly, the content of the oily part is appropriately 0.0001 to 60% by weight, but when the content of the oily part is less than 0.0001% by weight, the content of the oily part is too low, which may cause problems such as drying of the makeup area, so that the effect of makeup is reduced. When the content of the oil phase is more than 60% by weight, the oil part and the water phase part may be separated to cause a problem that the formulation collapses.

The oil-drop makeup cosmetic composition of the present invention can be prepared by sequentially injecting the water phase and the oil phase.

Purified water, moisturizing agent, chelating agent, gellan gum, xanthan gum, cation supplying agent (electrolyte), and water-soluble pigments, which are components of the water phase part of the present invention, can be divided into three groups and added.

The three groups may be divided into a first aqueous phase raw material, a second aqueous phase raw material, and a third aqueous phase raw material, and the first aqueous phase raw material may include purified water, a moisturizing agent, a chelating agent, gellan gum, and a cationic feed agent (electrolyte). , The second aqueous phase raw material may include xanthan gum, and the third aqueous phase raw material may include purified water and a water-soluble pigment.

The degree to which the viscosity collapsed by the dye was visually evaluated. The observed shapes of the compositions of Comparative Example 1 and Comparative Example 2 are shown in photos in FIG. 7.

In FIG. 7, the composition whose viscosity is maintained on the right side is a composition using xanthan gum and gellan gum of Comparative Example 1 as a thickener, and the composition whose viscosity on the left side is collapsed is a composition using the carbomer of Comparative Example 2 as a thickener.

Table 7 shows the visual evaluation of each composition of Comparative Example 1 and Comparative Example 2.

Comparative Example 1 Comparative Example 2 Spreadability Less Severe Viscosity height lowness

In the case of Comparative Example 1, despite the fact that the pigment was added, the spreadability was hardly observed and the composition could be confirmed. Accordingly, a high viscosity could be inferred.

In the case of Comparative Example 2, it was confirmed that the spreadability was severe due to the addition of the pigment. Accordingly, a low viscosity could be inferred.

Experimental Example 3. Microscopic observation according to the oil content

The appearance of the oil droplets contained inside the compositions of Preparation Examples 1 to 5 of the present invention was photographed to confirm the properties of the oil droplets.

The photographing was done through a microscope, and the photographs are shown in FIGS. 2 to 6, and the observation results are shown in Table 8.

Oil phase 5.0 wt% Oily part 10.0 wt% Oil phase 20.0 wt% Oil phase 40.0 wt% Oil phase 60.0 wt% shape Keep thinking Keep thinking Keep thinking Keep thinking Keep thinking size Very small littleness usually greatness Very large

As a result, as the oil phase compared to the total composition increased to 5.0% by weight, 10.0% by weight, 20.0% by weight, 40.0% by weight, and 60.0% by weight, the size of the oil droplets also increased. It was confirmed to keep.

That is, it was confirmed that the clarity can be maintained without changing the shape of the oil droplets up to 60.0% by weight of the oil phase.
