Description

Topical cosmetic composition for skin moisturization and skin tone improvement}

Disclosed herein is a topical cosmetic composition for moisturizing skin and improving skin condition comprising higher fatty acids, neutralizing agents and silicone elastomers.

The skin of the local area such as the elbow and the elbow has a lot of pigmentation, dryness, and exfoliation, and exfoliation, such as regular exfoliation, is apparently prominent and has a negative cosmetic effect. Although it is mainly related to keratin care to care for the skin of the topical area, it is difficult to recognize the effect of suppressing skin pigmentation, moisturizing, and exfoliating immediately because it requires a considerable period of time to show the effect of exfoliation.

On the other hand, many people have excessive melanin pigmentation or hyperpigmentation local areas that can cause abnormal pigmentation or pigmentation of the skin, and the skin texture looks rough due to wrinkles, keratin, etc. The cosmetics for improving the skin condition due to pigmentation, wrinkles, keratin, etc. are pigmented using functional cosmetics and powders that fundamentally improve skin conditions by acting on factors that generate pigmentation, wrinkles, keratin, etc. Cover the area (masking, masking), fill the bumpy area with wrinkles or keratin, and diffuse light into the area to temporarily divide the pigmentation, wrinkles, dead skin cells, etc. (soft focusing, soft focusing) Can be. In the latter case, that is, in the case of a cosmetic that temporarily masks pigmentation, wrinkles, and dead skin cells by causing diffuse reflection, excessive powder is added to have a heavy and stiff feeling, and when applied to the skin, its use is bound to be limited. In addition, due to the moisture absorption and oil absorption properties of the powder, the skin becomes dry and the adhesive force with the skin is reduced, causing a phenomenon of clumping and excitement on the skin, and thus has a problem that it is difficult to exhibit a continuous effect. Furthermore, in order to obtain an instant masking effect and a concealing effect using only powder and an elastomer, an excessive amount of the above components must be used, and in this case, there is a problem that the feeling of use is deteriorated.

Accordingly, the present inventors recognize a skin lightening effect immediately after application as a cosmetic composition for applying to the skin of a topical area where a lot of pigmentation such as elbows and heels occurs and is dry and exfoliating well. It is possible to complete the invention of a cosmetic composition capable of recognizing an immediate effect of improving skin texture by including a silicone elastomer.

[ Experimental Example 1] skin Lightning Check effect

The skin lightening effect of the six types of topical cosmetic compositions (Comparative Examples 1 to 4 and Examples 1 to 2) prepared in the preparation example was measured by the following method, and the results are shown in Table 2 below.

Specifically, 10 subjects evaluated the skin lightening effect by applying each of the above 6 types of topical cosmetic compositions to the topical area. Δ that is present and X that does not show the effect are denoted by X.

Comparative Example 1 Comparative Example 2 Comparative Example 3 Comparative Example 4 Example 1 Example 2 Perception of skin lightening effect X X △ X ○ ○

Among the six types of topical cosmetic compositions, Comparative Examples 2 and 4 had unstable formulations. Specifically, Comparative Examples 2 and 4 had poor composition stability and separation of the oil phase and the aqueous phase occurred, and a homogeneous form was not obtained. . This is because it does not contain a component that can serve as an appropriate level of surfactant.

In addition, among the six types of topical cosmetic compositions, Comparative Examples 1, 3 and Examples 1 and 2, in which separation of the oil phase and the aqueous phase did not occur, were applied by rubbing 30 times with 0.2 mg of synthetic leather. Then, the coated artificial leather was measured three times with a color difference meter (Spectrophotometer,; Spectrophotometer CM-5, KONICA MINOLTA OPTICS, INC, JAPAN), and the average value of the change in brightness (L) value is shown in Table 3 below.

Comparative Example 1 Comparative Example 3 Example 1 Example 2 Change in L value -0.35 0.5 3.24 4.25

As shown in Tables 2 and 3, Comparative Examples 1 and 2 and higher fatty acids that do not contain stearic acid and palmitic acid, which are higher fatty acids, are included, but do not contain sodium hydroxide or potassium hydroxide, which are neutralizing agents, and thus include higher fatty acid salts. Comparative Example 4, which was not, could not recognize the immediate skin lightening effect, and formulation instability was also observed. In addition, Comparative Example 3, which contains a higher fatty acid, but does not include a silicone elastomer, dimethicone/page-10/15 crosspolymer, has an immediate skin lightening effect compared to Examples 1 and 2 containing a higher fatty acid and a silicone elastomer. It was confirmed that it was difficult to recognize. Therefore, it was found that the topical cosmetic composition comprising a higher fatty acid, a neutralizing agent, and a silicone elastomer has excellent skin lightening effect that is immediately recognizable after application to the skin.

[ Experimental Example 2] Confirm the effect of improving skin texture

The effect of improving the texture of the skin of the four types of topical cosmetic compositions (Comparative Examples 1 to 4 and Examples 1 to 2) prepared in Preparation Example was measured in the following manner, and the results are shown in Table 4 below.

Specifically, 10 subjects applied each of the 6 types of topical cosmetic compositions to the topical areas to evaluate the effect of improving skin texture. At this time, the results of evaluation of 10 subjects were synthesized to recognize the effect of improving skin texture on average. In the case of ○, △ that the effect is slightly, and X that the effect is not seen are indicated.

In addition, among the six types of topical cosmetic compositions, Comparative Examples 1, 3 and Examples 1 and 2, in which separation of the oil phase and the aqueous phase did not occur, were applied to artificial leather, respectively, and enlarged images (Currency Detecting Microscope, x60) were taken. It is shown in FIG. 1. A of FIG. 1 is Comparative Example 1, B is Comparative Example 3, C is Example 1, D is an image taken after applying the composition of Example 2.

As shown in Table 4 and Figure 1, it does not contain all of the higher fatty acids (stearic acid and palmitic acid), neutralizing agents (sodium hydroxide or potassium hydroxide), and silicone elastomers (dimethicone/page-10/15 crosspolymer). In Comparative Examples 1 to 4, it was difficult to recognize immediate skin texture improvement, and it was confirmed that it was impossible to recognize skin texture improvement because there was little effect of filling the skin texture even in an enlarged image. Comparative Example 1, which does not contain higher fatty acids but contains a silicone elastomer and a neutralizing agent, is capable of recognizing immediate improvement in skin texture compared to Comparative Examples 2 and 3, but this is Example 1 including all three active ingredients. And the effect is not superior than 2, Comparative Examples 1 and 2 was also observed in formulation instability. Therefore, it was found that the topical cosmetic composition comprising a higher fatty acid, a neutralizing agent, and a silicone elastomer has an excellent effect of immediately recognizing skin texture improvement.

Therefore, the cosmetic composition comprising 0.1 to 10% by weight of the silicone elastomer as an active ingredient based on the total weight of the higher fatty acid, neutralizing agent, and composition according to one aspect of the present invention is a topical pigmented, dry, elbow, heel The skin lightening effect, skin texture improvement effect immediately recognized when applied to the site, and the skin moisturizing power are also excellent, so it is an excellent effect as a cosmetic composition for improving skin condition and skin moisturizing that can be applied to the skin of the local area where the pigment is deposited and dry. There is.
