Description

Cosmetic Composition Containing Capsule absorbed Water Soluble Extraction

The present invention relates to a cosmetic composition comprising a cosmetic capsule in which a water-soluble extract is absorbed, and specifically, to the skin by improving the stuffiness of the solid cosmetic and providing a moist feeling by absorption of the water-soluble extract in the shell constituting the capsule. It relates to a cosmetic composition capable of providing moisturizing power.

Makeup cosmetics have a limitation in that it is difficult to realize both coloring and moisturizing power at the same time. In particular, stick-type products manufactured by solidification have disadvantages in that they are stuffy and sticky when applied to the skin, since most of them are manufactured in an oily type without containing an aqueous component for stability of the contents.

Accordingly, there have been studies to add an aqueous component to the solid stick cosmetic composition to provide a refreshing feeling with a moisturizing effect, but it is very difficult to increase the moisture and moisturizing power while maintaining the stability of the solid stick formulation.

On the other hand, a technology for delivering a component contained in the encapsulated material to the skin by manufacturing it by including the encapsulated material in the cosmetic composition has been developed. The capsule material is dispersed in the cosmetic composition and collapses when applied to the skin, so that the material contained in the capsule can be delivered to the skin. However, in the case of a stick-type product, there is a problem in that the capsule is broken during the high temperature manufacturing process, or the capsule is not evenly distributed in the formulation and floats or is deposited, so it is difficult to develop a stable capsule in the solid stick formulation.

The present invention is to solve the above problems, and to provide a cosmetic composition comprising a capsule in which a water-soluble extract is absorbed, which can provide improved moisturizing power to the skin by improving the stuffiness of a solid cosmetic and giving a moist feeling of moisture. do it with

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. In general, the nomenclature used herein is those well known and commonly used in the art. In addition, in describing the embodiment of the present invention, if it is determined that a detailed description of a related known configuration or function interferes with the understanding of the embodiment of the present invention, the detailed description thereof will be omitted. In addition, embodiments of the present invention will be described below, but the technical spirit of the present invention is not limited thereto and may be variously implemented by those skilled in the art.

The cosmetic capsule according to the present invention consists of an inner material containing an oil-like material and a shell containing collagen to accommodate the inner material, and the water-soluble extract is absorbed in the shell.

In the present invention, the inner material is a material accommodated in the shell of the capsule, and may be an oil-like material such as liquid oil, oils and fats, waxes, butters, hydrocarbons, higher fatty acid esters, fatty acids, and higher fatty acid alcohols.

More specifically, it may be butters such as shea butter, mango butter, aloe butter, olive butter, cocoa butter, coffee butter, hemp seed butter, avocado butter, camellia butter, lanolin butter, and jojoba butter.

In addition, CAPRYLIC/CAPRIC TRIGLYCERIDE (MC), vegetable oils such as sunflower seed oil, almond oil, olive oil, ISONONYL ISONONANOATE, hexyllaurate (HEXYL LAURATE), PENTAERYTHRITYL TETRAISOSTEARATE, ISODECYL NEOPENTANOATE.

According to the present invention, the oil may have a density of 0.7 to 1.5 g/ml, preferably, a density of 0.9 to 1.1 g/ml at 20°C. In addition, it is preferable that the inner material of the oil component has a low density compared to the outer case.

When the inner substance of the oil component is encapsulated by the shell and then mixed with the oily trauma and formulated into a solid cosmetic composition, if the difference in density between the capsule and the trauma is large, the capsule may float or sink within the trauma. can According to the present invention, since the water-soluble extract is absorbed in the shell enclosing the oil component, when the capsule is mixed with oily trauma, it has a property of sinking by the nature of the water-soluble extract. Therefore, in the present invention, by adjusting the density of the inner material of the oil component to be lower than the density of the trauma, the cosmetic capsule in which the water-soluble extract is absorbed can be evenly distributed without sinking under the trauma.

The internal material may include, as well as the above-mentioned oil-like substances, skin whitening agents, wrinkle improvement agents, functional additives, sunscreen agents, vitamins, pigments, pearls, and the like.

Since the inner material according to the present invention is encapsulated with a shell, a problem such as agglomeration is not generated according to a temperature change in the cosmetic distribution process. In addition, by encapsulating unstable substances such as vitamins, efficacy can be stabilized. This encapsulated internal material is delivered to the skin as the shell collapses due to pressure or temperature change when cosmetics are used. These internal substances have the effect of providing luster and flexibility to the skin, or supplying elasticity and nutrition.

In the present invention, the shell (shell) serves to wrap and coat the inner material from the outside, and is mainly composed of a collagen component. By encapsulating the unstable internal material, the shell can play a role of stably protecting the internal material from being changed during distribution and manufacturing processes.

The collagen is a fibrous protein found in most animals, particularly mammals, and is a major protein component of connective tissues such as skin, blood vessels, bones, teeth, and muscles. Since collagen is involved in the amount of moisture in the skin, when used in cosmetics, it has an anti-aging effect on the skin.

In addition, the shell may be a multi-layered structure comprising one or more additional layers.

According to the present invention, various water-soluble extracts can be absorbed into the shell constituting the capsule. When the shell has a multilayer structure, various water-soluble extracts may be absorbed between the layers.

The water-soluble extract is an active ingredient extracted using water as an extraction solvent, and a plant extract or animal extract derived from plants such as trees, flowers, leaves, stems, fruits, and seeds may be used.

Specifically, the botanical extracts include aloe vera leaf extract, cranberry extract, peach seed extract, black willow bark extract, salvia leaf extract, centella asiatica extract, borage extract, wild mulberry root extract, cornus fruit extract, pomegranate extract, Night blooming cereus flower extract, cactus extract, chrysanthemum extract, baekyakja extract, acai berry extract, raspberry extract, rosehip fruit extract, peach extract, grapefruit extract, apricot extract or vitamin tree fruit extract can be used.

Specifically, the cactus extract may use a bogum cactus extract, a cochineal cactus flower extract, and a cochineal cactus fruit extract.

In addition, as the animal extract, royal jelly extract, propolis extract, silk extract, snail mucus extract, and caviar extract may be used.

In an embodiment of the present invention, a cactus extract, an alpine rose extract, and black bee propolis were used, but the present invention is not limited thereto, and various water-soluble extracts may be used.

Water used as an extraction solvent to obtain a water-soluble extract may use a temperature of less than 40 °C, preferably 0 to 20 °C water, more preferably 0 to 10 °C water, However, the present invention is not limited thereto. In addition, the water-soluble extract can be obtained by dissolving a part of a plant or animal-derived substance in an extraction solvent. In this case, the time for dissolving the material in water is preferably 1 to 60 minutes, but is not limited thereto.

When a water-soluble extract is directly added to a cosmetic to be prepared, there is a problem in that the extract is emulsified in an oily component or the contents are separated. However, when the water-soluble extract is absorbed into the shell constituting the capsule and added to the contents in the form of a capsule, the water-soluble extract can be stably added to the cosmetic. The water-soluble extract absorbed in the shell of the capsule is delivered to the skin when the shell collapses, improving the stuffy feeling of oily cosmetics and giving a fresh and refreshing feeling.

In addition, since the water-soluble extract has a polarity, the water-soluble extract may be leached from the trauma when the polarity of the trauma is high. Therefore, it is preferable that the trauma is low or non-polar so that the water-soluble extract can keep the shell of the capsule stable. The present invention is characterized in that the water-soluble extract can be stably preserved in the capsule by using the difference in polarity between the capsule and the trauma.

According to the present invention, the water-soluble extract is absorbed into the shell after the capsule is formed.

More specifically, the cosmetic capsule manufacturing method according to the present invention comprises the steps of: preparing a cosmetic capsule comprising an inner material containing an oily material and a shell containing the collagen and accommodating the inner material; and absorbing the water-soluble extract into the shell.

Here, the step of preparing the cosmetic capsule may be prepared by a known capsule manufacturing method, for example, the principle of a complex phase separation method.

According to the present invention, it is characterized in that after manufacturing a cosmetic capsule consisting of an inner material and a shell, the water-soluble extract is absorbed into the shell. For example, after preparing a cosmetic capsule, the capsule may be immersed in a desired water-soluble extract for a certain period of time to allow the water-soluble extract to be absorbed into the shell constituting the capsule.

The cosmetic capsule according to the present invention may have a particle size of approximately 1 to 2,000 μm. Preferably, it may be 100 to 1700 μm, more preferably 400 to 1500 μm. The size of the particles of the cosmetic capsule may be manufactured by adjusting the size of the particles according to the capacity of the inner material.

The cosmetic capsule according to the present invention may be included in 1 to 10% by weight, preferably 3 to 8% by weight, more preferably 4 to 7% by weight in the cosmetic composition.

The cosmetic capsule according to the present invention is stably distributed in the cosmetic, and when applied to the skin, the shell collapses and delivers the internal material to the skin. At this time, since the water-soluble extract is absorbed in the shell, it is possible to improve the stuffiness of oily cosmetics and provide a moist feeling to the skin when applied to the skin.

The cosmetic capsule according to the present invention may be prepared in various formulations of cosmetic compositions.

Specifically, the present invention is composed of an inner material containing an oily material and a shell containing collagen to accommodate the inner material, wherein the shell is a cosmetic capsule, characterized in that the water-soluble extract is absorbed; And it provides an emollient oil, a gelling agent, an emulsifier, and an external wound comprising at least one selected from the group consisting of a powder, a solid stick-type cosmetic composition.

Here, the trauma refers to ingredients excluding cosmetic capsules, and may include at least one selected from the group consisting of emollient oil, gelling agent, emulsifier and powder. In addition, it may further include a component commonly used in a cosmetic composition, but is not limited to the exemplary component.

The trauma according to the present invention may have a density of 0.7 to 1.5 g/ml, preferably a density of 1 to 1.2 g/ml at 20°C. In addition, it is preferable that the outer wound has a higher density than the inner material of the oil component.

When the cosmetic capsule according to the present invention is mixed with an oily trauma, the water-soluble extract is absorbed by adjusting the density of the inner material of the oil component to be lower than the density of the trauma because it tends to sink due to the nature of the water-soluble extract. There is an effect that the cosmetic capsules can be evenly and balanced without sinking under the trauma.

The emollient oil serves to soften the skin by creating a film that blocks the evaporation of moisture on the skin surface. As the emollient oil used in the present invention, all emollients and silicone oils commonly used in the manufacture of cosmetics can be used.

The emollient oil used in the present invention may have a polarity of 0.6 δa or less or non-polar. Since the water-soluble extract absorbed in the shell of the cosmetic capsule has polarity, when the polarity of the trauma is high, there may be a problem in that the water-soluble extract absorbed in the shell is leached into the wound. Therefore, it is preferable that the trauma is low or non-polar so that the water-soluble extract absorbed in the shell of the capsule is not leached. When the trauma or the emollient oil contained in the trauma is low or non-polar, the water-soluble extract may not be leached from the shell to the trauma, and may be stably preserved in the shell. As such, in the present invention, the water-soluble extract absorbed in the shell of the cosmetic capsule is not leached, and the cosmetic capsule is stably dispersed within the trauma by impregnating the water-soluble extract by differentiating the polarity of the cosmetic capsule. can have an effect.

The present invention will be described in more detail with reference to the following examples. These examples are only for illustrating the present invention, and it will be apparent to those of ordinary skill in the art that the scope of the present invention is not to be construed as being limited by these examples.

Examples 1-3: Cosmetic composition comprising capsules in which water-soluble extracts are absorbed

(1) Preparation of cosmetic capsules

After emulsifying MCT oil (Medium chain triglycerides) and gum arabic, the collagen was stirred at a speed of 100 to 4,000 rpm to mix, the pH was adjusted to 2.5 to 6.5, and polyanion and dilution water were added. Thereafter, after cooling slowly and rapidly cooling to 10° C., cosmetic capsules were prepared after cross-linking for one day. The prepared capsules were measured to have an average size of 1500 μm.

(2) Preparation of cosmetic capsules in which the water-soluble extract is absorbed in the shell

The cosmetic capsule prepared by the above process was immersed in a beaker containing a cactus extract, and the water-soluble extract was absorbed into the shell of the capsule for 30 minutes. In the same manner, cosmetic capsules in which alpine rose extract was absorbed into the shell and cosmetic capsules in which black bee propolis extract was absorbed into the shell were prepared, respectively.

(2-1) Preparation of cosmetic capsules in which water-soluble pigments are absorbed into the shell instead of water-soluble extracts

For reference, in order to visually observe the process of absorption of the water-soluble extract into the shell, 0.01 g of the pigment (RED 33 (CI 17200)) was dissolved instead of the water-soluble extract to absorb the pigment into the shell for 30 seconds.

As a result, as shown in FIG. 1, over time, it was observed that the pigment component was absorbed into the shell surface of the spherical cosmetic capsule.

2 is a photograph of the cosmetic capsule before and after the pigment is absorbed into the shell, and when the cosmetic capsule is immersed in the pigment, the pigment is absorbed into the shell of the cosmetic capsule, and it can be seen that the color is red as a whole. In addition, as a result of observing by attaching a microscope to the outer wall of the cosmetic capsule in which the pigment was absorbed, it was confirmed that the water-soluble pigment was formed in the form of droplets on the inner and outer wall of the shell, as shown in FIG. 3 . Through an experiment using a water-soluble pigment, it was possible to visually observe the process of absorption of the water-soluble extract into the shell and the appearance after absorption.

(3) Preparation of solid stick-type cosmetic composition

3 - 10 wt% of the cosmetic capsule in which the cactus extract prepared in the process of (2) is absorbed into the shell is put into the outer box and stirred, then degassed, molded in a mold and cooled, the solid stick of Example 1 A cosmetic composition was prepared.

In the same process, the cosmetic capsule in which the alpine rose extract was absorbed into the shell was put into the outer box to prepare the solid stick-type cosmetic composition of Example 2.

In addition, in the same process, the cosmetic capsule in which the black bee propolis extract was absorbed into the shell was put into the outer box to prepare the solid stick-type cosmetic composition of Example 3.

Comparative Example 1: Cosmetic composition comprising capsules in which water-soluble extracts are not absorbed

In the above example, except for the process of absorbing the water-soluble extract into the capsule, the rest of the process was performed as it is, thereby preparing a solid stick-type cosmetic composition comprising a capsule in which the water-soluble extract is not absorbed.

Comparative Example 2: A cosmetic composition comprising capsules and extracts in which the water-soluble extract is not absorbed

In the above embodiment, the capsule was prepared except for the process of absorbing the water-soluble extract in the capsule, and then the water-soluble extract was separately added during the preparation of the solid stick-type cosmetic composition, whereby the capsule and the extract in which the water-soluble extract was not absorbed were respectively included. A composition was prepared.

Comparative Example 3 : Cosmetic composition containing extract only without capsules

By omitting the capsule manufacturing process in the above example and adding only the water-soluble extract to the manufacturing process of the solid stick-type cosmetic composition, a cosmetic composition containing only the extract without the capsule was prepared.

Test Example 1 : Characteristic test of capsule with water-soluble extract absorbed

(1) Moisturizing and feeling measurement

After 50 female panels in their 30s and 40s were allowed to use the solid stick-type cosmetic compositions of Examples 1 to 3 and Comparative Examples 1 to 3 for 1 month, a sensory evaluation for moisturizing and feeling was performed.

The score was evaluated on a 5-point scale, and the evaluation criteria are as follows:

Example 1 Example 2 Example 3 Comparative Example 1 Comparative Example 2 Comparative Example 3 moisturizing 4.6 4.5 4.4 3 3.3 2.5 feeling 4.7 4.8 4.6 4 4.1 3.5

(5: very good, 4: excellent, 3: average, 2: poor, 1: very poor)

As a result, the cosmetic composition (Examples 1 to 3) comprising the capsule in which the water-soluble extract is absorbed in the shell is a case in which the extract is not absorbed (Comparative Example 1) or the cosmetic composition comprising the extract separately (Comparative Example) 2 and 3), it was confirmed that it exhibited more excellent moisturizing and feeling of use.

(2) Process extract Weight loss Measure

Example 1 Example 2 Example 3 Comparative Example 1 Comparative Example 2 Comparative Example 3 Degree of reduction of extract in the process
(About 80~85℃, 1hr) 5-10% 4-9% 6-10% - 90-95% 95-100%

The solid stick-type cosmetic compositions of Examples 1 to 3 and Comparative Examples 1 to 3 were heated in a WATER BATH (water temperature hot tub) at a temperature of 80 to 85° C. for 8 hours, respectively, and the weight before and after the measurement was measured, respectively, to obtain the water-soluble extract. The degree of weight loss was measured.

As a result, it was confirmed that when the extract was prepared by adding the extract directly to the trauma, more than 90% of the extract was reduced and the function was lost. On the other hand, when the cosmetic composition was prepared by absorbing the extract in the shell of the capsule, the degree of weight loss was very insignificant, about 5 to 10%, and it was found that there was almost no loss of the extract according to the manufacturing process.

(3) Capsule distribution measurement

Examples 1-3 Comparative Example 1 Comparative Example 2 Comparative Example 3 Capsule distribution chart Good floating floating -

In order to visually confirm the degree of distribution of the capsule within the trauma, the state of the capsule within the trauma was confirmed before adding the pigment and powder during the manufacturing process of the solid cosmetic composition.

As a result, as shown in Fig. 4, when the water-soluble extract was prepared by absorbing the water-soluble extract in the capsule, it was confirmed that the water-soluble extract was balanced by the nature of the oil component downward and the capsule was evenly distributed within the trauma (Fig. 4(a) )). On the other hand, when the water-soluble extract was added directly to the trauma without absorbing the water-soluble extract into the capsule, it was confirmed that the capsule was not evenly distributed and floated on the trauma (Fig. 4(b)).

Then, after completing the preparation of the solid cosmetic composition, the degree of distribution of the capsules within the trauma was visually confirmed.

As a result, as shown in FIG. 5 , when the water-soluble extract is absorbed into the capsule and prepared, it can be confirmed that the capsule is evenly distributed within the trauma (FIG. 5(a)). On the other hand, when the water-soluble extract is added directly to the outer box without absorbing the water-soluble extract into the capsule, the capsule floats on the upper end of the outer box, and when filling the stick-type cosmetic container, the upper end of the outer box gathers at the lower end of the container. As in b), it can be seen that the capsules are formed at the bottom of the stick.

Test Example 2: Measurement of stability of water-soluble extract according to polarity of traumatic oil

In order to confirm the stability of the water-soluble extract according to the polarity of the trauma oil, cosmetic capsules in which the water-soluble extract was absorbed were added to the oil of various polarities, and then the degree of leaching of the water-soluble extract was checked. In order to visually check the degree of leaching, a cosmetic capsule in which the water-soluble pigment prepared in Example (2-1) was absorbed into the shell was used. The leaching results are shown in Table 4 below.

*Intermediate polarity: 0.3< δa ≤0.6
*High polarity: 0.6 < δa

Representatively among the above results, the results of non-polarity (Experiment 1), intermediate polarity (Experiment 2), and high polarity (Experiment 6) are shown in FIG. 6 .

As shown in FIG. 6 , as the polarity of the trauma increased, the water-soluble pigment was leached, and it was confirmed that the solution around the capsule was dyed red.

After leaching was completed, the shell of the capsule was observed under a microscope. As shown in FIG. 7 , the pigment component was stably maintained in the shell in the oil of low and medium polarity of 0.6 or less, but the oil of high polarity higher than 0.6 It was confirmed that almost no pigment component remained in the shell of the capsule.

As such, the present invention provides excellent moisture and moisturizing power by absorbing the water-soluble extract into the shell of the collagen capsule, and when the water-soluble extract absorbed in the shell is applied to the solid cosmetic composition by controlling the trauma and the density of the capsule, the capsule It has the effect of allowing it to be evenly distributed in the formulation and stably preserved without leaching the water-soluble extract of the capsule due to the difference in polarity between the oil and the capsule.

As described above in detail a specific part of the content of the present invention, for those of ordinary skill in the art, this specific description is only a preferred embodiment, and the scope of the present invention is not limited thereby It will be obvious. Accordingly, it is intended that the substantial scope of the present invention be defined by the appended claims and their equivalents.
