INDUSTRIAL APPLICABILITY The cosmetic composition for alginic capsule disintegration according to the present invention can effectively and easily dissolve alginic capsules using a polymer having a chelating effect, not a chelating agent.

In addition, the cosmetic composition of the present invention can be applied to various cosmetic products including alginate capsules because the stability of the composition is enhanced by using a polymer having a chelating effect.

The present invention relates to a cosmetic composition for alginic capsule disintegration comprising a polymer having a chelating effect.

Specifically, the present invention includes a cosmetic composition for alginic capsule disintegration comprising a polymer having a chelating effect and an emulsifier.

More specifically, the present invention relates to a polymer having a chelating effect; Water base; And an oil-based base containing an emulsifying agent.

In the present invention, the polymer having a chelating effect may include both a natural polymer and a synthetic polymer. More specifically, in the present invention, the polymer may be selected from the group consisting of a carbomer, an acrylate / C10-30 alkyl acrylate crosspolymer, a polyacrylate crosspolymer- 6), hydroxyethyl acrylate / sodium acryloyl dimethyltaurate copolymer, ammonium acryloyldimethyltaurate (VP copolymer), sodium polyacrylate But is not limited to, one or more selected from the group consisting of sodium polyacrylate, algin, xanthan gum, and sclerotium gum. For the purpose of the present invention, the polymer is most preferred when using sodium polyacrylate, carbomer, or a mixture thereof, and when such a polymer is used in a formulation, it effectively dissolves the capsule and has good stability over time .

The polymer having the chelating effect is preferably at least one selected from the group consisting of carboxy, acrylate / C10-30 alkyl acrylate crosspolymer and sodium polyacrylate, and is preferably a carbomer, a sodium polyacrylate, or a mixture thereof In this case, for the purpose of the present invention, the alginate capsule is effectively melted and the stability over time is excellent.

The weight ratio of the carbomer and sodium polyacrylate of the mixture is 0.02 to 0.5: 1, 0.04 to 0.4: 1, 0.06 to 0.3: 1, or 0.1: 1. As the content ratio of the carbomer is relatively higher, the stability of the formulation is deteriorated. As the content ratio of sodium polyacrylate is relatively higher, the formulation stability is deteriorated and the feeling of use of the skin is deteriorated.

The polymer having the chelating effect may be contained in an amount of 0.7 to 2.0 parts by weight, 0.8 to 1.8 parts by weight, 0.9 to 1.6 parts by weight, or 1.0 to 1.4 parts by weight based on 100 parts by weight of the total composition. When the amount of the polymer having the chelating effect is less than 0.7 part by weight, the ability to dissolve the alginate capsule is lowered and the stability of the formulation deteriorates. When the amount of the polymer is more than 2.0 parts by weight, the stability of the formulation is lowered and the alginate capsule hardly melts due to the increase in hardness. It falls out.

In the present invention, an emulsifier having both hydrophilicity and hydrophobicity is used in order to prevent separation of the water phase and the oil phase in the aging stability portion. As the emulsifier used in the cosmetic composition, C12-22 fatty alcohol, C14-22 carboxylic acid, alkyl fatty acid ester, sugar fatty acid ester, polyethylene, or lecithin may be used, but they have a weak ability to emulsify. Have found that the emulsifying effect is significantly better when they contain ceteareth-20, glyceryl stearate, or a mixture thereof.

The emulsifier used in the cosmetic composition according to the present invention may be Ceteares-20, glyceryl stearate or a mixture thereof. In this case, the emulsifying effect of the present invention is most excellent and the stability with time is good. Particularly, a mixture of cetearase-20 and glyceryl stearate is more preferable as the emulsifying agent. The mixture of cetearyl-20 and glyceryl stearate is prepared by mixing Cetearase-20 and glyceryl stearate in a weight ratio of 0.5-4: 1, 1-3: 1, 1.5-2.5: 1, or 2: 1 . The higher the content ratio of cetearyl-20 is, the lower the stability of the formulation and the stability of the formulation is lowered even when the content ratio of glyceryl stearate is relatively high.

The emulsifying agent may be contained in an amount of 1.5 to 8 parts by weight, 2 to 7.5 parts by weight, 2.5 to 7 parts by weight, and 3 to 6.5 parts by weight based on 100 parts by weight of the entire cosmetic composition. When the amount of the emulsifier is less than 1.5 parts by weight, the hardness is lowered and the stability is lowered. When the amount of the emulsifying agent is more than 8 parts by weight, hardness of the alginate capsule is hardly dissolved and the feeling of use is deteriorated.

In addition to the emulsifying agent used in the cosmetic composition according to the present invention, the oil can be used as an oil-based base, and the oil plays a role of moisturizing and enhancing feeling of use. The oil may be at least one selected from the group consisting of squalane, dimethicone, ester oil and hydrocarbon oil.

In addition to the emulsifier, the emulsion base may contain 10 to 25 parts by weight or 15 to 25 parts by weight based on 100 parts by weight of the total cosmetic composition. When the content is less than 10 parts by weight, phase separation occurs and the spreadability is poor. When the content is more than 25 parts by weight, the hardness is increased and the capsules are not mixed.

The water base used in the cosmetic composition according to the present invention includes purified water, a humectant, and an additive. As the humectant, glycerin, 1,3-butylene glycol, dipropylene glycol, a natural solution and the like can be used. In addition, the other additives may include co-mdiol as a preservative, dex-panthenol having an anti-inflammatory effect, and the like.

The water base may include 55 to 75 parts by weight or 60 to 75 parts by weight based on 100 parts by weight of the entire cosmetic composition. When the content is less than 55 parts by weight, there is a problem of poor moisturizing. When the content is more than 75 parts by weight, there is a problem that phase separation occurs.

The cosmetic composition of the present invention may further contain a chelating agent in addition to the cosmetic composition to more easily dissolve the alginic capsule. The chelating agent may be at least one selected from the group consisting of trisodium ethylenediaminetetraacetic acid (EDTA 3Na), tetrasodium ethylenediamine tetraacetic acid (EDTA 4Na), sodium citrate, etc. commonly used in cosmetic compositions But is not limited thereto. For the purposes of the present invention, a chelating agent may be used to dissolve the alginate capsule more quickly and easily, although it may be omitted.

Experimental Example  One: Of polymer Chelating  effect

Calcium ion binding capacity (Calcium ion Binding Capacity) was measured in order to examine the chelating effect of each polymer in the present invention. 50 g of a polymer aqueous solution containing 0.5% by weight of each polymer was prepared. Subsequently, 5 ml of a 2% by weight sodium carbonate aqueous solution was added, and then 0.1 N sodium hydroxide was added until the pH became 11 or higher. Each of the polymer mixed solutions thus prepared was titrated with an aqueous solution of calcium diacetate monohydrate of 4.4% by weight, and the point of time when the turbidity completely changed was designated as the end point.

The calcium ion binding force was calculated by the following equation (1).

As shown in Table 1, it was found that the chelating ability of sodium polyacrylate was the most excellent. It was found that the chelating ability of the skeletal thimble, the algin, and the hydroxyethylacrylate / sodium acryloyldimethyltaurate copolymer was significantly lower than that of sodium polyacrylate and carbomer.

Example  1 and Comparative Example  1-2: Algin capsule Disintegration Cosmetics  Preparation of composition

In Example 1 and Comparative Examples 1 and 2, a cosmetic composition was prepared in the following manner according to the components and contents described in Table 1 below.

The polymer, carbomer and sodium polyacrylate were uniformly mixed with purified water using a disperser at 1500 rpm for 20 minutes and then heated to 70 to 75 ° C. The water phase and the oil phase were respectively weighed according to the components and contents in Table 2, and then heated to 70 to 75 ° C. After heating, the water phase and polymer were mixed at 4500 rpm for 3 minutes in a homomixer. The oil phase was slowly added to the water phase, and homogeneously mixed for 5 minutes at 4500 rpm in a homomixer. After mixing, tromethamine, a neutralizing agent, was added at the same temperature, and homogeneously mixed for 3 minutes at 4500 rpm in a homomixer. Then, the fragrance was added at 50 DEG C, homogenized at 4500 rpm for 3 minutes, and defoamed to prepare each cosmetic composition.

The stability and the degree of dissolving the alginate capsules were evaluated for the compositions prepared in Example 1 and Comparative Examples 1 and 2, and detailed evaluation methods and results are as follows.

Experimental Example  1: Formulation stability evaluation

The stability of the cosmetic compositions of the above Examples and Comparative Examples was measured and the results are shown in Table 3 below. Stability was evaluated by visually observing the phase stability of each cosmetic composition at room temperature, 40 ° C, 45 ° C, 50 ° C, 0 ° C, and a cycle for 4 weeks in an oven to confirm layer separation and precipitation. At this time, the cycle means cycling at -10 ° C, 0 ° C, 25 ° C, and 45 ° C for 6 hours, respectively. The results are shown in Table 3 below. (?: Stable,?: Slightly separated, X: separated or precipitated)

division Room temperature 40 ℃ 45 ° C 50 ℃ 0 ℃ cycle Oven Example 1 ○ ○ ○ ○ ○ ○ ○ Comparative Example 1 ○ ○ ○ ○ ○ ○ ○ Comparative Example 2 ○ ○ ○ ○ ○ ○ ○

As shown in the above Table 3, the layer separation did not occur under all conditions regardless of the type and content of the polymer.

Experimental Example  2: of alginate capsules Disintegration  Measure

The degree of dissolution of the alginic capsules of the cosmetic composition according to each of the above Examples and Comparative Examples was measured, and the results are shown in Table 4 below. The degree of dissolution was determined by weighing 36 g of each cosmetic composition and 9 g of an alginate capsule into a 100 ml beaker and measuring the amount of the remaining alginate capsule when it was mixed with Spatula for 30 seconds.

<Evaluation Criteria>

Lumps of alginate capsule remain (completely less): ○

Algin capsule remains (slightly less): △

Algin capsule not left (fully recorded): X

division Example 1 Comparative Example 1 Comparative Example 2 Remaining degree X ○ △

As shown in Table 4, when the alginate capsule was mixed with the alginate capsule for 20 seconds, the alginate capsule was not dissolved and remained as it was. It was found that Example 1 and Comparative Example 2 containing a polymer having a large chelating effect were melted when mixed with a capsule for 30 seconds. However, it can be seen that Example 1 using a polymer blend of two more melts the capsule better than Comparative Example 2 using only one polymer.

From the above results, it was found that the composition for dissolving the alginate capsule by using the polymer having the chelating effect was more effective in chelating effect than the other compositions under the respective conditions and effectively melted and stable in the alginate capsule.

Formulation example : A cream formulation containing alginate capsules Cosmetics  Produce

The cream formulations containing the alginate capsules were prepared by mixing 10 g of alginate capsules with 40 g of the cream formulations as in Example 1 of Table 2 above.
