Description

COSMETIC COMPOSITION COMPRISING A MATRIX FORMED OF CELLULOSE AND A METHOD OF MANUFACTURING THE SAME

The present invention relates to a cosmetic composition comprising a matrix formed of cellulose and a method for preparing the same.

Commercially available oil-in-water type cosmetic compositions include fatty acids and oil as oily components, and may include an aqueous phase containing purified water and an oily phase containing fatty acids and oil, and may include an oil phase. In order to completely emulsify the upper part, an additional emulsifier was often required.

When two liquid phases, an immiscible oil phase and an aqueous phase, are mixed by mechanical force (eg, using a mixer), thermodynamically unstable oil-in-water or water-in-oil type emulsions are created. Oil-in-water or water-in-oil type emulsions prepared using mechanical force have an opaque appearance because the oil phase (oil-in-water type) or water phase (water-in-oil type) is physically separated and only dispersed in the formulation.

Since the emulsion has a tendency to stabilize its shape according to the second law of thermodynamics, in order to change from an unstable property to a stable property, the oil phase and the aqueous phase tend to separate from each other, and as time elapses, the oil phase and the aqueous phase are separated.

The emulsifier is a substance that is added to prevent the separation of the emulsion and to stabilize the liquid phase. However, depending on the input amount of the emulsifier or the degree of thermodynamic instability of the liquid phase, the separation time between the oil phase and the aqueous phase is shortened and stability over time is deteriorated.

As another method, a cosmetic composition in which an oily component is first prepared in the form of a dense bead and uniformly dispersed in an aqueous phase has been developed. At this time, in order to form the bead shape, a coating layer formed of cellulose, corn starch, agar, gelatin, etc. is additionally formed in the oil phase component to maintain the shape of the oil phase bead as the coating layer. When the cosmetic composition formed in this way is applied to the skin, since the coating layer can be hardened, the shape of the bead cannot be easily destroyed and the shape is maintained, so that the oily component may not be applied, and the user may feel a foreign body feeling. Could.

In addition, an oil drop type cosmetic composition in which the oil phase containing oil is separated into fine droplets in the aqueous phase separately is used. However, since the oil drop has a relatively lower specific gravity than purified water, it is located in the upper layer of the cosmetic composition, and therefore, it is inconvenient to shake and mix during use.

Cosmetic composition comprising a matrix formed of cellulose

The cosmetic composition according to an embodiment of the present invention contains a solvent containing purified water, cellulose as a component for matrix formation, caprylic/capric triglyceride as an oily component, and a polyalcohol compound, and xanthan gum and carbomer as a thickener It includes a matrix formed of cellulose comprising at least one selected from the group consisting of.

Referring to FIG. 1 , by including the cellulose in the cosmetic composition, a matrix such as a fine mesh of cellulose is formed in the composition, and the oily component between the matrices can be evenly distributed throughout the cosmetic composition. In particular, in the case of the conventional oil drop type cosmetic composition, the oil component including the oil component floats or precipitates in the purified water due to the difference in specific gravity with the purified water. can do. In addition, in the cosmetic composition using a generally transparent container, an oily component may not float or precipitate, or a sense of foreignness in appearance such as a layer separation phenomenon may not occur.

Due to this effect, when the cosmetic composition is applied to the skin, the proportion of the oily component can be discharged from the container at a constant rate, so that the nutritional and moisturizing feeling of the oil included in the oily component can be effectively imparted to the skin.

As the solvent phase, purified water may preferably be ultrapure purified water. General purified water is water generally used in pharmaceuticals and cosmetics, and has a dissolved solid content of 1.0 to 0.5 ppm indicating purity, a size of 0.2 to 0.45 μm of a filter used to remove particulates and microorganisms in the manufacture of purified water, and a pH of It is weakly acidic. The ultrapure purified water has a very high purity with a dissolved solids content of 0.03 ppm, and the size of the filter used for preparing ultrapure purified water is 0.001 μm, which is used to remove 99.99% of microorganisms, and the pH is weakly acidic, so it is preferable when applied to the skin. In particular, ultrapure purified water can prevent the auto-oxidation reaction of the composition by removing metal ions as well as prevent protein aggregation by metal ions, so that the formulation can be evenly applied with low irritation to the skin.

The cellulose is included in the cosmetic composition to form a matrix in the cosmetic composition, and specifically, may include fiber phase cellulose.

The cellulose is cellulose prepared through a pre-treatment and pulverization process in wood fibers, and may be fibrous with a width of 5 to 50 nm and a length of 1 to 5 μm.

The cellulose forms a matrix-like three-dimensional network in purified water to improve dispersibility of components other than purified water, and collects oily components between the matrices. Accordingly, the oil component included in the oil phase component is not united or separated to form a drop (drop) in the cosmetic composition. In particular, the cosmetic composition according to the present invention does not coalesce between oil drops formed of oily components and stably maintains the shape of the oil drop, while the oil drop does not float on top of the composition and is stably dispersed in the aqueous phase of the cosmetic composition. there may be

The oily component is evenly distributed between the matrices formed by the above-described cellulose fiber phase, and may be included in the cosmetic composition for the purpose of effectively imparting nutrition and moisture to the skin when a user applies it to the skin.

Among the oily components, caprylic/capric triglyceride is a naturally-derived component extracted from coconut, and is used as a cosmetic component because it has good skin affinity and less irritation. It belongs to a type of fatty acid, and when applied to the skin, it has less stickiness while controlling shine. When used in combination with other constituents of the present invention, skin permeability increases and excellent spreadability can be ensured.

In particular, in the cosmetic composition of the present invention that does not use a separate emulsifier, caprylic / capric triglyceride is not separated from the components in the final composition, and compatibility can be ensured to be evenly dispersed between the matrix formed of cellulose. can

Among the oily components, the polyhydric alcohol-based compound may include at least one selected from the group consisting of glycerin, butylene glycol, methylpropanediol, and propanediol, and may preferably include glycerin.

The polyhydric alcohol-based compound is included to ensure compatibility so that caprylic/capric triglyceride, which is an oily component, can be stably and evenly disposed between the matrices formed of cellulose, and to ensure transparency of the finally manufactured cosmetic composition will be included for

The thickener is for securing long-term storage stability in the cosmetic composition. In particular, the matrix formed of cellulose is effective for evenly distributing the oil phase component, but layer separation may occur when stored for a long time due to the action of gravity. In order to solve this problem, the thickener specifically preferably includes at least one selected from the group consisting of xanthan gum and carbomer.

The cosmetic composition may additionally include other components in addition to the above-described components. Specifically, it may be at least one selected from the group consisting of disodium EDTA, propanediol, caprylyl glycol, and ethylhexylglycerin.

The cosmetic composition according to an embodiment of the present invention preferably has the following content in order to form a matrix and maintain the oil drop for a long period of time.

Specifically, based on 78 to 94 parts by weight of purified water, 0.3 to 1 parts by weight of cellulose, 2 to 4 parts by weight of caprylic/capric triglyceride, 4 to 12 parts by weight of a polyhydric alcohol compound, and 0.05 to 0.3 parts by weight of a thickener may be included. In particular, disodium EDTA among the other components is preferably included in a ratio of 1: 0.02 to 0.1 by weight based on the cellulose component in terms of compatibility with cellulose.

In the fibrous cellulose, which is a vegetable polymer used in an embodiment of the present invention, gelling may be promoted by salt. This effect is highest in potassium, and decreases in the order of potassium and sodium. The strength of the gelled material obtained from the cellulose fiber can be controlled by using the difference in the degree of gelation according to the type of salt. Among them, disodium EDTA, a compound containing a sodium salt, can be easily used to soften fibrous cellulose. When the fibrous cellulose is softened by controlling the gelation, it is easy to form the matrix of the above-described three-dimensional structure, and the ratio of the space formed in the matrix increases, so that the loading rate of the oil phase component can be increased.

In addition, other components additionally included may be included in an amount of 0.5 to 1.5 parts by weight based on 78 to 94 parts by weight of the purified water.

When the purified water is less than the above range, the dispersing power of the cellulose and the thickener may decrease, resulting in agglomeration of the final composition. Such agglomeration may reduce the spreadability when the user applies the cosmetic composition to the skin. In addition, when the dispersing force is reduced, the loading rate of the oil phase component may decrease. Furthermore, the particle size of the oil drop may be increased or the coalescence speed between the oil drop particles may be increased. When it exceeds the above range, coalescence between oil drop particles is promoted due to the lowered viscosity of the final composition, and stability over time may be deteriorated.

If the cellulose is less than the above range, it is difficult to form a three-dimensional matrix structure, so the loading rate of the oily component may decrease. A feeling of foreign body like time may be generated.

When the caprylic/capric triglyceride is less than the above range, the spreadability may decrease, and the nutritional and moisturizing feeling, which is the inherent effect of the cosmetic composition of the present invention, may decrease, and if it exceeds the above range, the loading rate of the oily component is reduced. and, since the oily component may float on the upper layer of the cosmetic composition, it is not preferable in terms of stability.

When the polyhydric alcohol-based compound exceeds or is less than the above range, it may be difficult to develop an oil drop phenomenon.

When the thickener is less than the above range, the layer separation of the cosmetic composition may be observed due to insufficient securing of long-term storage stability.

When the weight ratio of the cellulose to the disodium EDTA is less than the above range, the formation of a matrix with cellulose is weak, making it difficult to develop an oil drop phenomenon.

The caprylic/capric triglyceride and the polyhydric alcohol-based compound may be included in a weight ratio of 1: 0.5 to 3 by weight. When the weight ratio of caprylic / capric triglyceride and polyhydric alcohol compound is less than the above range (the polyhydric alcohol compound is trace amount), the effect of lowering the interfacial tension of purified water is reduced, so the expression of the oil drop phenomenon may be inhibited, If the above range is exceeded (the polyhydric alcohol compound is excessive), the transparency of the final composition may be too high and the specific gravity of the composition may increase, so that the size of the oil drop shape may become too large, and the feeling of use or spreadability may be deteriorated.

Method for manufacturing a cosmetic composition comprising a matrix formed of cellulose

The cosmetic composition including the matrix formed of cellulose is difficult to produce in a one-component reaction, and may be subjected to the following process.

Specifically, the method for producing the cosmetic composition according to an embodiment of the present invention is a two-component process, comprising the steps of mixing a solvent containing purified water, cellulose, and a thickener to form a one-component composition, a polyalcohol-based compound and a Forming a two-component composition by mixing prilic/capric triglyceride and mixing the first and second liquids may be included.

First, in the first solution, purified water, cellulose and a thickener are mixed so that the matrix can be formed evenly from the cellulose fibers. In addition, in the second liquid, a polyhydric alcohol-based compound and caprylic/capric triglyceride are mixed as oily components, so that the caprylic/capric triglyceride is evenly dispersed so that an oil drop phenomenon can be expressed.

When all the above-mentioned components are simply mixed in a one-component process, or one or more of the oil phase components are mixed in one liquid (liquid containing purified water and cellulose, etc.) without mixing in two liquids, a matrix is formed During the course of time, the oil drop (fine droplet) shape merges with each other as time passes in the composition, and stability over time is insufficient, or the oil phase component is separated in the upper layer, resulting in layer separation such as a band.

Among the oily components, the polyhydric alcohol-based compound may include at least one selected from the group consisting of glycerin, butylene glycol, methylpropanediol, and propanediol, and may preferably include glycerin.

The thickener preferably includes at least one selected from the group consisting of xanthan gum and carbomer.

The cosmetic composition may additionally include other components in addition to the above-described components. Specifically, it may be at least one selected from the group consisting of disodium EDTA, propanediol, caprylyl glycol, and ethylhexylglycerin.

Specifically, based on 78 to 94 parts by weight of purified water, 0.3 to 1 parts by weight of cellulose, 2 to 4 parts by weight of caprylic/capric triglyceride, 4 to 12 parts by weight of a polyhydric alcohol compound, and 0.05 to 0.3 parts by weight of a thickener may be included.

The other components are preferably added in the one-liquid manufacturing process, and the additional components may be included in an amount of 0.5 to 1.5 parts by weight based on 78 to 94 parts by weight of the purified water. In addition, in order to secure the stability over time of the cosmetic composition, disodium EDIT is preferably included in a ratio of 1: 0.02 to 0.1 by weight based on the cellulose component in terms of compatibility with cellulose.

The caprylic/capric triglyceride and the polyhydric alcohol-based compound may be included in a weight ratio of 1: 0.5 to 3 by weight.

The first and second liquids are preferably included in a weight ratio of 80:20 to 95:5. If it is less than the above range, the oil floats on the upper layer and stability is not good, and if it exceeds the above range, it is difficult to obtain a moisturizing feeling and nutrition characteristic of the formulation.

Hereinafter, the present invention will be described in more detail through examples. These examples are only for explaining the present invention in more detail, and it is to those of ordinary skill in the art to which the present invention pertains that the scope of the present invention is not limited by these examples according to the gist of the present invention. it will be self-evident

Oil phase component compatibility test

In order to confirm the compatibility between the caprylic/capric triglyceride and the polyhydric alcohol-based compound, a composition was prepared by mixing in the following composition and ratio.

Ingredients (g) Preparation Example 1 Preparation 2 Preparation 3 Preparation 4 Caprylic/Capric Triglycerides 10 10 10 10 glycerin 20 Butylene Glycol 20 methyl propanediol 20 propanediol 20

The result was taken as a photograph, and it was set as FIG. In the case of Preparation Example 1 (No. 1), it was confirmed that caprylic/capric triglyceride in glycerin was dispersed by forming small oil drops. In the case of Preparation Example 2 (No. 2), it was confirmed that caprylic/capric triglyceride in butylene glycol was dispersed and quickly coalesced and separated. In the case of Preparation Example 3 (No. 3), similar to butylene glycol, it was confirmed that caprylic/capric triglyceride was dispersed in methylpropanediol and quickly combined. In the case of Preparation Example 4 (No. 4), caprylic/capric triglyceride was dispersed in a very small form in propanediol and was not separated, but an oil drop was not seen. From the above results, it was confirmed that glycerin and propanediol were good for the dispersibility part, and it lowered the interfacial tension of caprylic/capric triglyceride well, and propanediol was best mixed with caprylic capric triglyceride, In the oil drop phenomenon, it was confirmed that glycerin was most expressed.
