Description

TECHNICAL FIELD [0001] The present invention relates to a composite coating powder for cosmetics, and a cosmetic composition comprising the same. BACKGROUND ART [0002]

The present invention relates to a composite coating powder for cosmetics and a cosmetic composition comprising the same, and more particularly to a cosmetic composition containing a lipid complex having excellent moisture retention as a skin barrier strengthening component on the surface of an inorganic powder and a silicone and silane component having excellent water repellency and lubricity The present invention provides a cosmetic powder for cosmetic use which is improved in moisturizing property in addition to the skin color correcting effect inherent in an inorganic powder for cosmetics and has a skin protection effect by improving and strengthening skin barrier function, And a cosmetic composition containing the same.

Generally, make-up cosmetics can be classified into base make-up cosmetics mainly applied to the face and point make-up cosmetics applied to eyes, eyebrows, lips, and the like. Base makeup cosmetics formulated with a powder and a liquid, cream, Is used to produce three-dimensional and volume sense or transparency by arranging the skin color of the entire face naturally and uniformly, and point makeup cosmetics such as eyeshadow, mascara, eyebrow, eye line, or lipstick are used to locally color or shade And make-up cosmetics have been variously expanded in color due to the everyday use of color television and smartphone. Today, almost all areas of color hue Used "He said.

Base make-up cosmetics are used as a foundation cosmetics to prevent dryness of the skin and provide flexibility to supply smooth, moist and healthy skin by supplying water to the skin. By applying color cosmetics to the face and so on, the skin color is expressed beautifully, It is a cosmetic product to hide skin defects such as spots and freckles which can not be covered by basic cosmetics.

Therefore, the make-up cosmetics should be thinly applied to the skin to be able to exhibit a high skin color correction effect without imposing a burden on the skin. Therefore, the inorganic powder used in makeup cosmetics has good spreadability and skin affinity, good skin feel, Smooth feeling, water and oil resistance, and oil resistance are required.

Examples of typical powders for cosmetics include inorganic powders such as talc, mica (muscovite), sericite (sericite), kaolin, titanium dioxide, zinc oxide and the like, and they are used as mixed powders of two or more kinds, .

Here, the conventional mixed powder for cosmetics in which two or more kinds of the inorganic powders are mixed is inferior in adhesion to the skin, so that the powder is excited by the lapse of time after coating and dropped off due to sweat or moisture or the powder tends to aggregate There is a problem in that it is inconvenient that the makeup should be frequently corrected and the powder may block the skin pores and cause skin diseases.

On the other hand, conventional surface-modified powders for cosmetics are generally obtained by treating silicon, silane, lecithin, wax, amino acid, metal soap and the like in order to improve the skin fit performance. However, most widely used are surface active agents such as methicone, , Dimethicone, branched dimethicone, and acrylated dimethicone, and alkylsilane compounds such as octylsilane.

Although the silicone compound and the alkylsilane compound have an advantage of having excellent water repellency property and lubricity, the lack of moisturizing property on the skin is the biggest disadvantage of the silicone compound and the alkylsilane compound. .

As a result, the inorganic powder to which the above-mentioned conventional surface modification method is applied is not sufficiently satisfactory because of problems such as moisturizing property, skin affinity and durability at the time of applying the skin, There is a problem that it is difficult to apply it.

Therefore, there has been a demand in the art for the development of makeup cosmetics having satisfactory skin protection functions while satisfying all the functions or physical properties required for makeup cosmetics as described above.

Referring to this skin protection function, the skin performs a primary barrier function to protect the body from the external environment. In particular, the stratum corneum present in the outermost layer of the skin controls the loss of moisture and electrolytes through the skin, And functions as a skin barrier to prevent external harmful factors from penetrating into the human body.

The structure of the stratum corneum is composed of intercellular lipids filling corneocytes and keratinocytes. The intercellular lipids in the stratum corneum are ceramides, fatty acids and cholesterol derivatives. It has been reported that the multilamellar structure is one of the most important factors in performing the barrier function of the skin. Particularly, the composition of the ceramide and its relative composition ratio play an important role.

In order to maintain healthy skin, normal skin barrier function is required, and the abnormalities of the skin barrier function mentioned above include psoriasis, acute irritant contact dermatitis, acute occupational dermatitis, diaper dermatitis, allergic dermatitis, atopic dermatitis, , It is known to be associated with chronic occupational dermatitis, psoriasis, hypertrophic scar, keloid scar, cheilitis, lamellar ichthyosis, etc., It has also been reported that abnormal skin barrier function is accompanied by abnormal skin barrier function.

Therefore, normalization of skin barrier function or enhancement of skin barrier function in the above-mentioned skin disease or abnormal or dry or abnormal skin is important for the treatment of skin diseases and normalization of skin function.

Since the skin with the abnormality of the skin barrier function described above is apparently different from the healthy skin of the non-lesion, in this case, the use of the makeup cosmetic is effective for the homogeneous skin color correction, but the sensitivity Or dry skin, or skin diseases such as those mentioned above, use of makeup cosmetics has a limited use because it is likely to exacerbate the abnormality of skin barrier function.

Conventionally, the present applicant has found that by coating a silicone oil such as pseudoceramide and dimethicone on an inorganic powder or by coating a lipid complex containing pseudoceramide on an inorganic powder, a surface treated powder having excellent skin moisture resistance, water resistance, skin adhesion, However, even though ceramide is a major cause of skin barrier function abnormality, pseudoceramide alone has been found to be effective for the prevention of skin barrier function. The present inventors have completed the present invention as a result of repeated studies on formulations capable of restoring and strengthening the skin barrier function in order to overcome the limitations of existing make-up cosmetics.

Accordingly, a first object of the present invention is to provide a functional composite coating powder for cosmetics having an effect of enhancing and strengthening a skin barrier function by a lipid complex while maintaining the function of the inorganic powder itself, which is one of the main components of makeup cosmetics, .

A second object of the present invention is to provide a functional composite coating material for cosmetics which is obtained by mixing a silicone compound or an alkylsilane compound having excellent water repellency and lubricity but poor moisturizing property and a lipid composite exhibiting excellent moisture retention by moisture absorption and retention through a multilayer lamellar structure To provide a powder.

A third object of the present invention is to provide a functional composite coating powder for cosmetics having a soft feeling, an excellent skin protection effect, a high water repellency and an excellent dispersibility.

A fourth object of the present invention is to provide a cosmetic composition for cosmetics which contains the functional composite coating powder for cosmetics and which can be effectively used for skin which is difficult to use in general make-up cosmetic due to damage of skin barrier function such as sensitive skin, dry skin, To provide a skin-friendly cosmetic composition containing the same.

The lipid complex is composed of 5 to 20 wt% of ceramide, 5 to 10 wt% of cholesterol or its derivative, 20 to 40 wt% of fatty acid, and 30 to 50 wt% of alcohol based on the total weight of the lipid complex , The above ceramides may be composed of 1 to 5% by weight of natural ceramides and 4 to 15% by weight of alkanolamides, but this is not restrictive and optional in the present invention.

As the natural ceramides and pseudoceramides, alkanol amide has a structure that alternately arranges the hydrophobic layer and the hydrophilic layer so that the hydrophilic layer has a large amount of water and the hydrophobic layer blocks the movement of moisture, thereby maintaining the moisture in the skin, By controlling the migration to substances other than water, it exerts a protective function with keratinocytes.

The above-mentioned natural ceramides are commercially available in a variety of products extracted from microorganisms and the like. Alkanolamide as the above-mentioned pseudoceramides can be obtained by reacting myristoyl stearamide with monoethanolamine, Amide monoethanolamine, palmityl arachidamide monoethanolamine, or any mixture thereof, which are also commercially available from the present applicant.

In the present invention, it is needless to say that only the alkanolamide may be used as the pseudoceramide without using the natural ceramides.

Examples of cholesterol and its derivatives for constituting epidermal lipid-like conditions include cholesterol, cholesteryl acetate, cholesteryl stearate, cholesteryl palmitate, cholesteryl hydroxystearate, cholesteryl nonanoate, Sterol, or any mixture thereof. This component exhibits skin conditioning and skin protection effects and contributes to the formation of multilamellar liquid crystal structures when mixed with the ceramides and the fatty acid components described below in the specific proportions as described above.

Examples of the fatty acid for constituting a state similar to the epidermal lipid component include palmitic acid, stearic acid, arachidic acid, behenic acid, palmitoleic acid, oleic acid, linoleic acid, linolenic acid, arachidonic acid, ≪ / RTI > In addition, various plant derivatives such as a glyceride mixture may be formulated for the same purpose. Examples thereof include palm oil, palm kernel oil, coconut oil, olive oil, grape seed oil, academia oil, sunflower seed oil and castor oil . However, fatty acids or glycerides with chain lengths of 8 or less may be undesirable because they have skin irritation and may have negative effects on the formation of multiple lamellae.

As other components other than the above-mentioned components, higher alcohols such as cetyl alcohol, stearyl alcohol, behenyl alcohol, or any mixture thereof may be used for the purpose of further stabilizing the multilamellar liquid crystal phase, A lubricant such as octyldodecanol, squalane, etc. may be added.

In the present invention, silicone oil and alkylsilane are added for improving water repellency and lubricity and feeling of use. Examples of the silicone oil include methylhydrogenpolysiloxane, dimethylpolysiloxane, dimethylsiloxane, methylphenylpolysiloxane, methylphenylsiloxane, organopolysiloxane , Octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, or any mixture thereof.

As the above-mentioned alkylsilane, octylsilane can be typically used.

In the present invention, the composite coating treatment of the surface of the inorganic powder using the lipid composite of the multi-lamellar structure including the ceramides and the silicone oil or the alkylsilane enables the skin to have a superior moisturizing effect of ceramide, Oil, or alkylsilane, and excellent durability, and excellent durability. Further, by complementarily compensating for the agglomeration of the ceramide and the inferior feeling of use and the insufficient moisture retention of the silicone oil or the alkyl silane, It is possible to provide a cosmetic having unique skin barrier function improvement and strengthening effect, as well as excellent skin affinity and skin adhesion, good feeling on use, persistence and water repellency.

In the present invention, the composition ratio of the components constituting the lipid complex is important for forming a multilamellar structure similar to a multilamellar structure represented by intercellular lipid of the skin. It is believed that the pseudoceramide and natural ceramide are similar in mechanism of action but different in molecular structure.

Here, when the content of ceramide and cholesterol exceeds the above-mentioned range, or if they are used alone, there is a fear that the tendency of agglomeration of the liver becomes excessively strong, so that the multilamellar structure may not be formed well and the feeling of use may be lowered. , There is a possibility that the effect of strengthening or improving the skin barrier is weakened and the moisture retentivity is lowered, which is not preferable.

On the other hand, when the content of the fatty acid exceeds or falls below the above-mentioned range, there is a possibility that smooth formation of the multilamellar structure may not be achieved and the possibility of moisturizing deterioration is increased.

When the content of alcohol is less than the above range, the dissolution of the ceramides may not be smooth. Conversely, when the alcohol content exceeds the above range, the formation of the multilamellar structure may be obstructed, which is not preferable .

In the present invention, the addition amount of the silicone oil or the alkylsilane added for the purpose of enhancing the water repellency, the feeling of use, and the durability is important with respect to the addition of the ceramide. When the addition amount is less than 1.9 wt% There is a fear that the above-mentioned effect may be inadequate and mutual agglomeration of the ceramide components may occur, as well as a feeling of use and water repellency may be lowered, and conversely, It may also be undesirable because the effect of enhancing or improving the moisturizing and skin barrier function may be insufficient.

In the composite coating powder according to the present invention as described above, the weight of the powder itself is 80 to 98% by weight based on the total weight of the composite coating powder, and when it exceeds 98% by weight, , And conversely, if it is less than 80% by weight, the feeling of use may be lowered, which is also undesirable.

The content of the composite coating powder according to the present invention in the cosmetic may vary depending on the formulation but may be in the range of 1 to 99% by weight.

Formulations of the cosmetic composition comprising the composite coating powder according to the present invention may be in the form of powders and base makeup cosmetics formulated with a liquid, cream, or stick type foundation, or cosmetics such as eye shadow, mascara, eye lash, eye line, Point make-up cosmetics.

The composite coating powder according to the present invention can be prepared by any of a wet process and a dry process, and in general, the wet process is a process in which a surface treatment can be performed stably While there is an advantage, the process is complicated, the cost is high, and the yield is low. On the other hand, the dry method has advantages that the powder receives the physical force and the heat directly, but the cost is low and the process is simple and efficient.

Ceramides are required to have a large amount of solvent and high temperature conditions in order to coat powders because the melting point is 100 ° C or higher. However, when a multilamellar structure is formed by applying a specific lipid complex as in the present invention, the phase transition temperature is about 48 ° C So that the amount of the solvent used can be reduced and powder coating can be performed at a relatively low temperature.

Natural mica, natural ceramides, or similar ceramides, myristoyloxostearamide monoethanolamine, myristyl arachidamide monoethanolamine, palmityloxostearamide monoethanolamine, palmityl arachidamide monoethanolamine, The lipid complex composed of any mixture, cholesterol or a derivative thereof and a fatty acid and an alcohol may be dissolved in a solvent such as isopropanol or mixed with a silicone oil or alkylsilane to effect surface coating on the powder surface at the same time, The surface of the powder can be coated by surface coating treatment in this order.

A method for producing a composite coating powder according to the present invention by a wet method is as follows. A lipid composite containing ceramides is dissolved in an alcohol solution such as isopropanol, and then a powder is added thereto and stirred to coat the powder surface. , And pulverized to a constant particle size.

Specifically, a lipid complex containing ceramides is added to an alcohol maintained at a temperature of about 50 ° C by a bathing method in a constant temperature water bath, and the mixture is completely dissolved by using an agitator. Thereafter, the inorganic powder is gradually added with stirring After stirring, the mixture is filtered using a vacuum pump or the like, dried and then pulverized with a hammer mill or the like to obtain a composite coating powder.

Here, the silicone oil or alkylsilane may be dissolved together with the lipid complex, or may be separately dissolved, and then the coating may be carried out before or after the coating of the lipid complex.

The wet method has a disadvantage in that the surface treatment can be carried out with stability, but the yield is low.

Next, a method for preparing a composite coating powder according to the present invention by a dry method will be described. The coating composition is structurally stabilized by dissolving a lipid complex including ceramides in a solvent, spraying the coating uniformly, and then heat-treating the coating.

Specifically, the inorganic powder is dissolved in a solvent such as isopropyl alcohol, acetone or the like by dissolving a lipid composite containing a silicone oil such as methylhydrogenpolysiloxane or dimethylpolysiloxane or octylsilane and the above ceramide in a solvent such as isopropyl alcohol or acetone, , And then the coating layer is structurally stabilized by heating to about 80 to 200 캜.

Here, the silicone oil or alkylsilane may be dissolved or separately dissolved together with the above-mentioned lipid complex to perform the lipid complex before, after, or simultaneously with the coating.
