Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a cosmetic composition of a polyol-

The present invention relates to cosmetic compositions of in-oil polyol formulations comprising metal oxides.

In general, people instinctively pursue beauty. One of the many ways to pursue beauty is whitening, which means whitening is beautiful and whitening. The whitening effect in such a skin becomes possible by inhibiting the production of melanin or inhibiting the movement of melanosome. For the skin whitening function, various plant extracts and compounds have been developed as whitening ingredients.

However, the effect of this general whitening ingredient is that it takes a long time for the user to realize the effect, and the user feels that the whitening is not practically quick. As a result, on the market, there is an ever-on-the-spot whitening product that immediately brightens the face when the product is applied.

The effect of such an immediate whitening product is mostly effected by metal oxides such as titanium dioxide, zinc oxide and titanated mica. Calamine, which is a mixture of zinc oxide and iron oxide, (Korean Registered Patent No. 1,590,803). Since these metal oxides have a high refractive index and make skin color look bright, they give an excellent immediate whitening effect.

On the other hand, in today's complex and busy modern society, consumers prefer multi products that have multiple effects on one product rather than a mixture of products. Especially, recently, global warming shortens spring and fall, summer and winter become longer, and the need for skin moisturizing care due to the dryness of the skin is greatly increased. Also, cosmetics for makeups There is a growing need.

A conventional makeup cosmetic composition is formulated to be a water-in-oil type, an underwater type or an oil-based dispersion type, and an oil-based dispersion type is mainly used for a formulation for enhancing the moisturizing power. However, in the case of the oil-dispersed formulation, since the content of the oil must be increased in order to increase the moisture-holding power, there is a problem that it is not suitable to feel the actual moisturizing feeling by giving mainly oil feeling and shielding feeling to the moisturizing feeling. A non-aqueous, aqueous polyol formulation has been developed.

However, there have been no products of in-oil polyol formulations that simultaneously provide immediate whitening, gloss improvement, and moisturizing power, including metal oxides.

[ Experimental Example  One]

Depending on the content of PEG-silicone elastomer In-water polyol  Confirm the stability of the formulation

In order to confirm the stability of the oil polyol formulation containing the calamine, viscosity change and stability evaluation of the compositions of Example 1, Examples 7, 8 and 12 to 17 were carried out.

The formulations of Examples 1, 7, 8 and 12 to 17 were prepared and stored in a thermostatic chamber at 30 캜, and initial, next day, 3-day and 7-day viscosities were measured. In addition, when each of the formulations of the Examples was placed under severe conditions for 30 days, it was confirmed whether phase separation occurred and the phase stability was shown.

 The viscosity is measured by the internal resistance of the spindle rotating and represented by the liquid. Viscosity is measured using a Brookfield RV Viscometer, and the unit is in centipoise (cPs). Measurement spins were measured at a speed of 6 rods and 20 rpm for 2 minutes. The smaller the degree of change in viscosity (viscosity increase / decrease ratio), the better the stability of the formulation.

As a result, as shown in Table 5, it was confirmed that the compositions of Examples 1, 8, 12, and 13 containing the PEG-silicone elastomer had better formulation stability than that of Example 7, which did not contain them. Further, it was confirmed that the formulation stability of Example 1, which is 3% as compared with Example 8 in which the content of the PEG-silicone elastomer is 1%, is more excellent.

It was confirmed that when the content of the PEG-silicone elastomer was 5 and 10%, the viscosity of Examples 12 and 13 was high without fluidity and was impaired in the usability of the formulation.

Looking at Examples 14-17, which contain a general silicone elastomer that is not a PEG-silicone elastomer, Example 14, which contains 1% of a common silicone elastomer, has lowered viscosity over time and undergoes phase separation, % In the case of Example 15, it was confirmed that the viscosity was maintained but the phase separation phenomenon was confirmed, and it was not effective in stabilizing the formulation.

Therefore, it is confirmed that the PEG-silicone elastomer content is excellent when the content is 1 to 5% by weight, more preferably 2 to 4% by weight, more preferably 3% by weight.

Formulation of composition and confirmation of moisturizing effect depending on presence or absence of color

In order to confirm the formulation and the moisturizing effect depending on the presence or absence of the color, the compositions prepared in Comparative Examples 1 to 3 and Examples 1 and 7 were evaluated for moisturizing effect.

Specifically, the composition of Comparative Examples 1 to 3 and Examples 1 and 7 was applied to eight adult males and females by applying a 2 ㎕ / cm ² each of the compositions of Arhaback in a circle and waiting for 30 minutes, The moisture content of the skin was measured using a Corneometer (CM825 courage Khazaka electronic GmbH, Germany).

The coneometer is a sensor that measures the moisture content of the surface of the skin by static charge capacitance measurement and measures moisture content within 10 μm to 20 μm. The moisture content of the skin was measured in advance by using a coneometer at constant temperature and humidity (22 ± 2 ° C, 50 ± 10% humidity) before the application, and the results are shown in Table 6 below.

In the case of moisture content, the amount of water before and after application of the armhavumb site was compared because of the large individual difference and site difference. As shown in the following formula (2), the average water content improvement ratio of eight persons was derived to confirm the moisturizing effect. The percentage improvement in water content (%) is a measure of how much moisture is added to the skin before application.

As a result, as shown in Table 6, it was confirmed that the moisturizing effect of Example 1 of the in-oil polyol formulation was superior to that of Comparative Examples 2 and 3 of the water-in-water type and the water-in-water type. In addition, it can be confirmed that the moisturizing effect of such an oil polyol formulation is better than that of Comparative Example 1 in which there is no chromamine.

Depending on the formulation and the calamine content of the composition Instant whitening  Check the effect

In order to confirm the immediate whitening effect according to the formulation and the calamine content of the composition, an immediate whitening effect of the composition of Comparative Example 2 of the water-in-oil type formulation and of the composition of the oil-in-water type polyol formulation of Examples 1 to 7 was evaluated.

For evaluation of immediate whitening, specifically, to examine the change in skin brightness upon application of one time, eight adults and eight women were given the composition of Comparative Example 2 and Examples 1 to 7 in a circle of Arbatak to prepare 2 μl / cm ² After 30 minutes of application, The skin brightness is quantitatively measured using CM-2600d (Minolta, Japan).

The CM-2600d uses the Lab color space to quantify the L (lightness), a (rad to green) and b (yellow to blue) values of the skin's brightness with minimal external light effects. In this test, the skin brightness is evaluated using the L * value, and the higher the L * value, the brighter the skin. In this test, the skin brightness of the test site was measured before and after using the sample.

The L * value, which is the brightness of the skin surface, was measured before and after application of the same area where the color difference was relatively small, because the individual difference and the area difference were large. The average of ΔL * values before and after the application of the measured L * values of the eight subjects was derived to confirm the whitening effect immediately.

As a result, as shown in Table 7 and FIG. 1, it was confirmed that the composition of Example 1 of the polyol formulation in water was superior to the composition of Comparative Example 2 of the water-in-oil type formulation immediately in whitening effect. As the content of the coloramine increased, .

Skin Gloss Meter is a device that measures the amount of laser light emitted from a 635nm semiconductor laser diode reflected from the skin. The skin glossiness of the test area was measured three times with Skin Gloss Meter, and the average value was evaluated. The higher the gloss, the higher the measured value, and the worse the measured value. The skin grease increase rate was calculated by the following equation (3).

division Glossy growth rate (%) Comparative Example 1 0.02 Comparative Example 2 3.73 Comparative Example 3 3.05 Example 1 9.08 Example 2 1.12 Example 3 3.97 Example 4 9.59 Example 5 10.51 Example 6 10.63 Example 7 8.83

As a result, as shown in Table 8 and FIG. 2, the gloss increase rate of Example 1 was higher than those of Comparative Examples 2 and 3, and it was confirmed that the effect of improving the glossiness in the oil polyol formulation was better than that of the water- In the polyol formulation, it was confirmed that the effect of improving the gloss was improved as the content of calamine was increased.

Therefore, it was confirmed that the effects of improving the glossiness were remarkably excellent even in the formulations of Examples 4 to 7 containing a large amount of calamine.

Confirmation of formulation stability according to contents of calamine and titanium dioxide

In order to confirm the stability of the oil polyol (P / O) formulation containing the coloramine or titanium dioxide, the change in viscosity according to the content of each component was confirmed. The viscosity changes and stability of the compositions prepared in Examples 1 to 6 and 9 to 11 of the oil polyol formulation were evaluated.

The formulations of Examples 1 to 6 and 9 to 11 were prepared and stored in a thermostatic chamber at 30 캜, and initial, next day, 3-day, and 7-day viscosities were measured. The viscosity is measured by the internal resistance of the spindle rotating and represented by the liquid. Viscosity was measured using a Brookfield RV Viscometer, and the unit is in centipoise (cPs). Measurement spins were measured at a speed of 6 rods and 20 rpm for 2 minutes. The smaller the degree of change in viscosity, the better the stability of the formulation.

The viscosity increase and decrease rates in the following Table 9 were calculated using the above-described Equation 1 and rounded to the second decimal place.
