Description

Water-soluble patch type cosmetic composition {COSMETIC COMPOSITIONS OF WATER-SOLUBLE PATCH TYPE}

The present invention relates to a water-soluble patch-type cosmetic composition, and more particularly to a cosmetic composition that can be usefully used as a mask pack by stabilizing various active ingredients effective for wrinkle improvement, whitening, and acne, and in particular, a water-soluble patch in the form of a film during distribution The present invention relates to a water-soluble patch-type cosmetic composition which is kept intact and readily soluble in water-soluble patches.

Today, the cosmetics industry is rapidly evolving, and the product line of masks that can achieve more fundamental skin improvement after functional cosmetics is in the spotlight.

Accordingly, with the development of technology, disposable masks have been developed that do not require cumbersome preparation procedures, unlike conventional products, and various types of mask products that are effective in improving whitening and wrinkles are appearing one after another.

These masks function to maintain moisture and keep the skin supple with moisture coming from the subcutaneous skin by supplying moisture, moisturizers and emollients to the stratum corneum of the skin and the occlusive effect of the mask. In addition, it has an excellent cleansing effect by removing the contamination of the skin surface at the same time as the adsorption and drying / peeling.

On the other hand, it shows excellent effects such as improving skin wrinkles, whitening, strengthening moisturizing, and antioxidant, but limited to practical applications due to the problem that discoloration and discoloration occur easily due to external stimuli such as air and moisture, and the potency decreases. Active research is being conducted to stabilize the active ingredients, and when the cosmetics are applied to the skin, the effectiveness of the effective ingredients penetrates into the skin may be reduced.

Therefore, it is important to formulate so as to effectively stabilize the active ingredient while increasing the skin absorption rate of the active ingredient when applied to the skin, the most common technique is to use a phospholipid emulsion. It is mainly used as a method of adding lecithin, polyol, fatty acids, and the like, known as transdermal absorption accelerators.

By the way, in the cosmetic formulation containing a number of additives such as oil, surfactant, water, etc. with respect to the phospholipid emulsion, Republic of Korea Patent Registration No. 0320087 (Reference 1), Republic of Korea Patent No. 0439068 (Reference 2) and US Patent US 5,034,228 (Ref. 3) all discloses methods for stabilizing active ingredients such as retinol, but these are all carried out in aquatic systems and retain the destabilization effect of water and maintain the ability to immobilize the lamellar array. There was a problem that did not substantially stabilize the active ingredient because it did not provide a means to.

On the other hand, Republic of Korea Patent Publication No. 10-2009-0014633 (Ref. 4) "solid-liquid separation cosmetic preparations" is a solid cosmetic formulation of the functional cosmetic ingredients inactive in the liquid state by encapsulating them with liposomes or nanoparticles when used Separable cosmetic preparation, characterized in that it is mixed with a liquid formulation is disclosed, Korean Patent Publication No. 10-2018-0044167 (Reference 5) "Cosmetic composition containing a freeze-dried ball to stabilize the active ingredient" mushroom There is disclosed a patent using a polysaccharide and collagen derived from the lyophilized body in the form of a porous structure, completely dissolved in a small amount of aqueous solution, increased stability, and excellent skin absorption rate when applied to the skin. However, these compositions are easily oxidized in air or light, and active ingredients that do not last long in aqueous solution inevitably have long-term stability in the liquid state, and the porous structure can maintain long-term stability but has disadvantages of formulation and stickiness. The feeling is not good.

According to the active ingredients, the mask pack can be used for various effects such as moisturizing, nourishing, keratin care, and strengthening skin elasticity. However, since most mask packs contain large amounts of water, it is difficult to dissolve high concentrations of active ingredients. It is not easy to stabilize and deliver to the skin.

In particular, the physiological activity of anthocyanin is known to be anti-aging activity, antimicrobial activity, antimutagenic activity, anti-cholesterol activity, anti-ulcer activity, antioxidant activity, eye protection activity, especially in the case of antioxidant activity than tocopherol, a natural antioxidant 5 ~ It is known to exhibit 7 times stronger antioxidant activity, and studies have also been reported in the United States suggesting an anthocyanin preventive effect of cancer or senile dementia. Anthocyanins are currently being used in health functional foods, cosmetics, medicines, dyes, etc. due to their physiological activity. When the anthocyanin component is used in cosmetics, it can be seen that the anti-oxidative activity has the effect of improving skin wrinkles and preventing aging.

Since anthocyanins containing a large amount of these polyphenols are easily oxidized by water, heat, or light, they are encapsulated in liposomes or lamellar liquid crystals and applied to cosmetics or dissolved in oils or W / O formulations to block water or light. Although it is applied to the formulation, even in such a case, it is difficult to secure stability in the long term because the titer of the active ingredient decreases or discolors and odors occur with the change over time.

In addition, the hydrogel or patch-type film of the active ingredient has a problem that it is cumbersome to adhere to the skin using a support and then remove it, or it is very sticky using an adhesive or the like and causes skin irritation.

In addition, as another related art in this regard, Korean Patent Publication No. 10-2018-0067177 (Ref. 6) "Skin Attachment Patch", Korean Patent Publication No. 10-2011-0062277 (Ref. 7) "Freezing Two-component porous skin improvement cosmetic composition prepared by a drying method, Korean Patent Publication No. 10-2017-0139962 (Reference 8) "Hydrogel patch for wrinkle improvement containing a peptide to control neurotransmitters as a useful ingredient Although these cosmetic compositions have been proposed, these cosmetic compositions must be easily prepared during the initial patch manufacture of the film, stable in an unbroken state during distribution, and should be easily dissolved in water to minimize foreign substances during actual use. The structure of a satisfactory composition has not been proposed at all.

No. 5,034,228 Reference 4: Korean Patent Publication No. 10-2009-0014633 Reference 5: Republic of Korea Patent Publication No. 10-2018-0044167 Reference 6: Republic of Korea Patent Publication No. 10-2018-0067177 Reference 7: Korean Patent Publication No. 10-2011-0062277 Reference 8: Korean Patent Publication No. 10-2017-0139962

In addition, Comparative Examples 2 to 7 were prepared by the same process as in Comparative Example 1, Comparative Example 2 is a content ratio when preparing a general cosmetic containing 5% retinol, Comparative Example 3 is a content when preparing a general cosmetic containing 5% anthocyanin Comparative Example 4 is the ratio of the content of the general cosmetics containing 5% of lasveratrol, Comparative Example 5 is the ratio of the content of the general cosmetics containing 5% of azulene, and Comparative Example 6 is of general containing 5% of riboflavin It is a content ratio in the production of cosmetics, Comparative Example 7 is a content ratio in the production of general cosmetics containing 5% retinyl palmitate.

In addition, Examples 2 to 7 are prepared by the same process as in Example 1, Example 2 is the content ratio when preparing a water-soluble patch containing 5% retinol, Example 3 is the content ratio when preparing a water-soluble patch containing 5% anthocyanin Example 4 is a content ratio of preparing a water-soluble patch containing 5% of lasveratrol, Example 5 is a content ratio of preparing a water-soluble patch containing 5% of azulene, and Example 6 is a water-soluble patch containing 5% of riboflavin It is a content ratio in preparation, and Example 7 is a content ratio in preparing a water-soluble patch containing 5% retinyl palmitate.

The results of the stability test [Experimental Example 1] and transdermal absorption evaluation test [Experimental Example 2] for a plurality of samples prepared according to the content ratio of Table 1 above are shown in Tables 2 and 3 below.

Experimental Example 1 Stability Test

Table 2 shows the results of confirming the titer measurement by storing all of a plurality of samples under the same temperature condition of 50 ° C. for 1 month. As can be seen in Table 2, the results of the content analysis of Comparative Examples 1 to 7 are reduced to 50 to 70%, while it can be seen that they are maintained at 90% or more from Examples 1 to 7.

Experimental Example 2 Transdermal Absorption Evaluation Test

In order to evaluate how much the active ingredient was absorbed into the skin, it was measured using a multiple transdermal permeation evaluation system (Franz cell). Transdermal absorption is commonly referred to as Transdermal Drug Delivery System (TDDS). It is a system that effectively delivers a drug to a desired location by absorption of the drug through the skin. By applying such a transdermal absorption experimental model it can be usefully applied to evaluate the efficacy of the percutaneous absorption of bioactive substances.

In this evaluation, the degree of transdermal penetration of the sample was evaluated over time using a micro pig skin similar to human skin using the Franz cell type (see FIG. 3). The samples provided in Comparative Examples 1 to 7 and Examples 1 to 7 were precisely weighed, mixed 1: 1 with 1,3 butylene glycol, and applied to the micro pig skin for 2 hours and 12 hours. 2 ml of the cell receptor was analyzed by HPLC, and the results are shown in Table 3 below.

Experimental results show that the skin penetration rate is different for each active ingredient, but the active ingredient content of the Example is much higher than that of the comparative example.

That is, according to the present invention, after attaching the water-soluble patch to care for the troubled areas, the mask is attached once more to provide intensive moisturizing and sedation to the entire face, thereby providing a substantial effect on the skin.

This invention is specifically composed of two steps (STEP 1,2).

STEP 1: Preparation of water-soluble patches containing active ingredients

Anthocyanins, rasveratrol, azulene, riboflavin, vitamin C, and retinol and retinyl palmitate, which are excellent in anti-wrinkle effects, are made into patches and absorbed directly onto the skin to absorb wrinkles. It is a water-soluble patch mask that makes the skin firm or restores pigmented areas to the affected skin. It gives fine wrinkles and elasticity to the skin and brightens the skin.

In this case, the film forming agent is selected from the group consisting of glucose, Pectin, Xanthan Gum, and combinations thereof, which are natural polymer polymers.

STEP 2: Moisturizing / Calm Mask Sheet

By attaching a mask sheet with moisturizing and soothing effects, it dissolves the active ingredient attached to 1 to maximize skin penetration, thereby intensively supplying nutrients to the skin and managing it as a firm skin.

In the present invention as described above, the mask sheet is widely known in the art to which the present invention pertains, and thus, without particular limitation, a special description thereof will be omitted, and the preparation of the water-soluble patch will be described in more detail.

The preparation of the water-soluble patch according to the present invention excludes the chemicals used to crosslink conventional polymers and repeatedly performs the freeze-thaw method to form natural crosslinking defects and dissolve the useful components therein. It is possible to produce a water-soluble patch.

Each active ingredient is suitably 0.1 wt% or more and 50 wt% or less, and preferably 5 to 10 wt% is an optimal content. Efficacy is less than 0.1% by weight, over 50% by weight is likely to be supersaturated and precipitate, and may also cause skin irritation. Preferably the active ingredient can be seen the optimum efficacy in a state of minimizing the stimulation when using 5 to 10% by weight.

As shown in FIG. 1, the water-soluble patch is dispersed in a first step by dispersing a natural polymer polymer such as pectin and xanthan gum in a solvent. At this time, the solvent is water; Lower alcohols such as glycerin and butylene glycol, or mixed solvents thereof are possible, and water or water / ethanol mixed solvents, which are harmless to the skin, are preferably used. (S1)

In step 2, the solution prepared in step 1 is frozen in a dispersion solution in which one or more active ingredients such as glucose, anthocyanin, lasveratrol, azulene, riboflavin, retinol, retinyl palmitate, and vitamin C are selected and dissolved. Repeat the thaw method. Freeze-thaw method (freeze-thaw method) is a method of freezing the natural polymer polymer below the freezing point and then thawing above the freezing point. Through the freeze-thaw method, a network structure is formed between the polymer polymers to be bonded by self-assembly. The degree of crosslinking can be increased without adding a crosslinking agent. (S2)

The water-soluble patch prepared by the above-described method is used after molding (S3) in the form of a film or the like according to the shape for the care of a sheet shape or a local area for the convenience of use. According to the present invention, after attaching the water-soluble patch to care for the annoying area, the mask sheet for intensively supplying nutrition to the entire face is attached once more, thereby increasing the skin absorption rate of the active ingredient and maximizing efficacy.

Such a water-soluble patch according to the present invention implements a film form by combining pectin (xecthan) and xanthan gum (Xanthan Gum) to maintain the film form, the water-soluble patch according to Table 1 is glucose, pectin, Only the case of setting the ratio of xanthan gum to 1: 1: 1 is explained, but the ratio of glucose, pectin and xanthan gum of the natural polymer polymer also needs adjustment.

Pectin, a film forming agent of such a water-soluble patch, forms a network structure and forms a conjugation bond with Xanthan Gum to increase the strength of the film and fill it with a glucose component in the interspace therebetween to form a film type. .

In this case, the base is composed of 40% by weight of glucose (Glucose), 15% by weight of Pectin, 45% by weight of Xanthan Gum, 40% by weight of Glucose, 45% by weight of Pectin, xanthan It may also consist of 15% by weight of Xanthan Gum. Considering the appropriate content range, based on 40% by weight of glucose (Glucose), 15 to 45 parts by weight of pectin, 45 to 15 parts by weight of xanthan gum (Xanthan Gum) can be composed, but glucose (Glucose) 40 It is preferably composed of 30% by weight, 30% by weight of Pectin, and 30% by weight of Xanthan Gum.

In this case, when the content ratio of pectin is increased in the preparation of the water-soluble patch according to the present invention, the film network structure becomes hard and the film does not break during distribution but is stable but does not dissolve well in water during actual use, resulting in a large amount of residue. . On the other hand, when the content of pectin is lowered, the shape of the film is weakened and the breakage during distribution becomes worse, so it is not preferable as a cosmetic. Therefore, in the present invention, to make the net to minimize the residue with the optimum pectin (Pectin) content and to increase the strength by adding a Xanthan Gum in the form of a conjugation bond between the mesh to increase the strength but the residue Minimize.

In addition, the water-soluble patch according to the present invention should not be broken during distribution as a cosmetic but must be slightly dissolved in water during actual use. For this purpose, it is manufactured in the form of a film with the optimal content of pectin and xanthan gum in the production of water-soluble patches to maintain a stable form in distribution and to dissolve in water during practical use. Filled with dried glucose components in the form of a mask sheet, mist, and skin toner when used in the actual use, hydrophilic (Hydrophilic) components are easily dissolved from strong glucose and finished with a film with minimal residue.

(Film Formation Experiment)

Analysis results of the film formation degree of the water-soluble patch prepared according to the content ratio of the glucose (Glucose), Pectin (Pectin), Xanthan gum (Xanthan Gum) are as shown in Table 4 below. In this case, to prepare a water-soluble patch, dissolved in a combination condition of pectin and xanthan gum (Examples 1 to 15) according to glucose content change, coated on coated paper, and then dried at 70 ° C. with hot air to form a dried film having a thickness of 70 μm. Prepared.

In this case, the film forming degree is divided into "1.0: very bad", "2.0: bad", "3.0: normal", "4.0: good", "5.0: very good". According to this, it can be seen that the film forming degree is good (or very good) under the conditions of Examples 1 to 9.

(Broken test)

On the other hand, the experiment on the degree of phase stability (brokenness) of the water-soluble patch made of a film form is as shown in Table 5 below. This is an experiment on the phase stability (brokenness) during the distribution of the water-soluble patch, the water-soluble patch samples prepared for each condition (Examples 1 to 15) were stored in the chamber, respectively, to test the phase stability (brokenness). Its experimental condition is 25 ℃ in the chamber temperature, 10% humidity, 7days.

In this case, the degree of phase stability (brokenness) is divided into "1.0: well broken", "2.0: finely broken", "3.0: good", "4.0: sagging", "5.0: very sagging". According to this, it can be seen that the degree of phase stability (brokenness) is good under the conditions of Examples 7 to 9.

(Solubility and residue experiment)

On the other hand, the experiment on the solubility and residue generation degree of the water-soluble patch made of a film form is as shown in Table 6 below.

In this case, as shown in Figure 2 to make a water-soluble patch in the form of a 70㎛ thick eye patch to test the solubility of the film in practical use and to confirm the occurrence of the residue. More specifically, the solubility and residues of the water-soluble patch prepared under each condition (Examples 1 to 15) were tested after attaching a mask sheet under the same condition and attaching a mask sheet under the same condition after 10 minutes.

In this case, the solubility degree is divided into "1.0: very bad", "2.0: bad", "3.0: normal", and "4.0: good". According to this it can be seen that the degree of solubility is usually above the conditions of Examples 7-15.

The degree of residue generation is divided into "1.0: severe residue", "2.0: fine residue", and "3.0: none". According to this it can be seen that the degree of residue generation also in the conditions of Examples 7 to 15.

As described above, embodiments of the present invention have been described in detail, but the scope of the present invention is not limited thereto, and the scope of the present invention extends to the range substantially equivalent to the embodiments of the present invention.
