To this end, the present invention provides a wash-off type pack cosmetic composition comprising an aqueous phase, wherein the aqueous phase comprises nylon powder and ethanol.

The wash-off type pack cosmetic composition according to the present invention rapidly changes from a transparent color to a white color upon drying of a pack, thereby enabling easy visual confirmation of the pack holding time and washing time, as well as solving the problem of dryness and irritation And has functions such as moisturizing and sebum adsorption.

FIG. 1 is a photograph of a color development process with time after applying the cosmetic composition of Example 2 to skin. FIG.

Hereinafter, the present invention will be described in detail.

The present invention provides a wash-off type pack cosmetic composition capable of imparting sensory differentiation through color change after application together with sebum adsorption, and visually indicating the time to wash the mask pack and the like.

The packaged cosmetic composition contains nylon powder and ethanol for color change over time. At this time, the cosmetic composition is able to know the pack end time as the nylon powder changes color from transparent to white as the ethanol evaporates with water after applying the skin.

At this time, ethanol is preferably contained in the total cosmetic composition in an amount of 0.1 to 30% by weight. If the above range is exceeded, there is a problem in that the discoloration time is accelerated, and it is difficult to notify the appropriate pack end time, and the skin may be irritated have.

The nylon powder is spherical in shape and can absorb a large amount of oil because of its porosity, and has excellent skin sticking ability. In addition, the average particle size of silica is usually 10 to 20 占 퐉, which is larger than that of silica particles of 6 to 9 占 퐉. This difference in particle size is more effective in absorbing and absorbing oil, and even when a small amount is used, the color quickly develops, which makes it possible to remove the pack without drying.

The nylon may be hydrophilic nylon 6 or nylon 6/12. At this time, it is preferable that the content of the nylon powder is included in the pack cosmetic composition in an amount of 5 to 70% by weight. When the amount is less than 5% by weight, it is difficult to confirm discoloration from a transparent color to a white color. When the amount is more than 70% by weight, not only the feeling of use is lowered but also excessive sebum is removed and skin irritation occurs.

At this time, the ratio of each composition constituting the cosmetic composition according to the present invention is such that the sum of the total composition is 100%

(I) 5 to 50% by weight of a moisturizing agent,

(Ii) 5 to 70% by weight of a nylon powder,

(Iii) 0.1 to 30% by weight of ethanol,

(Iv) 0.05 to 5% by weight of an incrementing agent, and

(V) an aqueous phase containing water as the remainder

.

Usable humectants include glycerin, erythritol, maltitol glycerin, propylene glycol, 1,3-butylene glycol, sorbitol, polyglycerin, polyethylene glycol, 1,2-pentanediol, isoprene glycol, polyhydric alcohols; Amino acid, sodium lactate, and sodium pyrrolidonecarboxylate; and an NMF component such as xyloglucan, carrageenan, pectin, mannan, cardan, galactan, glycocon, chondroitin, locust bean gum, glucan, hyaluronic acid, sodium hyaluronate, Collagen, a water-soluble polymer substance as a mucopolysaccharide; Dimethyl polysiloxane, methylphenyl siloxane; Culture supernatant of lactic acid bacteria and bifidobacteria; And combinations thereof.

The water is distilled water, preferably deionized distilled water.

In addition, since the thickening agent is a component for allowing the formulation to have a proper viscosity for application to the skin, the aqueous thickening agent can be used as long as it is known in the art. Preferably at a concentration of 0.05 to 5% by weight based on the total weight of the cosmetic composition. If the content is less than 0.05% by weight, there is a problem in that the adhesive force with the skin is insufficient when applying the skin. When the content is more than 0.5% by weight, the viscosity is lowered. Representatively, a water-soluble buildup selected from the group consisting of carbomers, polyacrylamides, ammonium acryloyldimethyltreate / vp copolymers, xanthan gum, cellulose ethers, polyvinyl derivatives, alginates, polyacrylates, I can do it.

Preferably, the wash-off type pack cosmetic composition of the present invention may comprise a pigment to visually maximize color change. For example, one kind of pigment selected from the group consisting of titanium dioxide, talc, mica, iron oxide, sericite, boron nitride, silica, kaolin, zinc oxide, and zirconium oxide is possible.

The wash-off type pack cosmetic composition according to the present invention not only has excellent sebum adsorbing ability but also imparts sensory differentiation through color change and can visually show the pack end time, thereby increasing the reliability and preference of the cosmetics to consumers .

Hereinafter, preferred embodiments of the present invention will be described in order to facilitate understanding of the present invention. However, the following examples are provided to further understand the present invention, and the present invention is not limited by the examples.

Experimental Example  One. Mask Pack  Color change appearance time

Using the cosmetic compositions of Examples 1 to 3 and Comparative Examples 1 to 5 prepared as described above, the time when white color was developed after application to skin was measured, and the results are shown in Table 2 below.

division Expression time (min) Example 1 10'10 Example 2 3'22 Example 3 1'30 Comparative Example 1 8'15 Comparative Example 2 1'11 Comparative Example 3 5'50 Comparative Example 4 2'41 Comparative Example 5 11'00

Referring to Table 2, in Examples 1 to 3 in which the content of nylon was changed, it was confirmed that the higher the nylon content, the faster the color development time.

In addition, in Comparative Examples 1 and 2, in which the content of ethanol, which is supposed to induce rapid color development, was adjusted in order to facilitate the evaporation of the cosmetic, the color development time was prolonged in proportion to the ethanol content. It was confirmed that the color development was also accelerated even in the case of Comparative Example 4 in which the content of the moisturizing agent was increased.

In addition, in the case of using silica, in Comparative Example 5, the expression rate was remarkably slower than in Example 2 containing the same amount of nylon (40 wt%). In Example 1 containing 10 wt% of nylon of Example 1 Expression rates were similar to those of the control group.

Experimental Example  2. Effect of removing sebum

Experiments were carried out as follows with the wash-off type pack cosmetic compositions of Example 2 and Comparative Example 5 as follows.

First, five male subjects were measured for sebum levels before the start of the test and the cosmetic compositions of Example 2 and Comparative Example 5 were applied to each of the cheek areas and maintained for 15 minutes, washed, and then the change in sebum level was measured . The results are shown in Table 3 below.

Subject Before the experiment (㎍ / ㎠h) After the experiment, the amount of fat (㎍ / ㎠h) Sebum reduction rate% Example 2 Comparative Example 5 Example 2 Comparative Example 5 Example 2 Comparative Example 5 One 62 65 44 55 29% 15% 2 78 77 58 70 25.6% 9.1% 3 82 76 62 72 24.3% 5.2% 4 93 94 73 86 21.5% 8.5% 5 88 92 71 83 19.3% 9.7%

As can be seen from the results of Table 3, it can be confirmed that the amount of sebum in the case of Example 2 was reduced more than that of Comparative Example 5 immediately after the experiment.

Experimental Example  3. Feeling  And skin irritation evaluation (sensory evaluation)

After the experiment of Experimental Example 2, the satisfaction degree of feeling of the subjects participating in the experiment was evaluated at 1 to 5 points. The evaluation results are shown in Table 4.

Example 1 Example 2 Example 3 Comparative Example 1 Comparative Example 2 Comparative Example 3 Comparative Example 4 Comparative Example 5 Satisfaction with removing sebum 3.8 4.3 4.4 3.5 4.1 3.9 3.1 3.5 Color expression time satisfaction 3.0 3.5 4.2 2.8 4.1 3.3 3.8 1.1 Moistness 4.2 4.1 3.2 3.8 3.9 2.8 3.9 2.3 stimulus 4.5 4.8 3.8 4.2 3.5 3.5 4.3 4.5 * 5 (very good, no irritation)? 1 (very bad, severe irritation)

The satisfaction of removing sebum was higher when nylon was used than when silica was used in the same amount.

In the case of using nylon in comparison with the case of using the same amount of color in terms of color development time and moisturizing degree, satisfaction was remarkably high.

The satisfaction of Comparative Example 1 in which no ethanol was contained in the color development time was relatively low, which indicates that the evaporation rate is somewhat slow. Also, the higher the content of nylon, the higher the satisfaction with color expression time.

When the content of ethanol was high, the degree of satisfaction was low. Also, when the content of nylon was high at 60%, the satisfaction was low.
