The present invention relates to a transparent high moisturizing cosmetic composition using no oil. More specifically, the highly moisturizing cosmetic composition of the present invention (a) one or more selected from the group consisting of glycerin and its derivatives; And (b) PEG. PPG-17. 6 copolymers (dipolymer) and dipropylene glycol (dipropylene glycol) at least one selected from the group; containing a non-sticky emulsified oily feeling and excellent moisture retention.

The development of a moisturizing product is a step further from a product that simply gives a moisturizing effect to dry skin, and at present, the moisturizing enhancement technology is being used to improve the efficacy of functional ingredients in many areas such as whitening, wrinkles, and skin regeneration.

There are many ways to achieve high moisturizing cosmetics, but the most common method is to control the oil phase. That is, as a method of increasing the amount of oil or wax contained in the oil phase, this method can simply increase the moisturizing power and the lasting moisturizing power, but the absorption is slowed down due to the reduction of use, and the negative effects such as stickiness and shine are likely to occur simultaneously.

In another method, glycerin, propylene glycol, 1.3-BG, polyhydric alcohols such as sorbitol, and the like are combined with or surround moisture to allow the water to stay in the skin. Natural moisturizing fats (NMFs), which are known to play an important role in skin hydration in the stratum corneum, also belong to this category. The disadvantage of this category of moisturizing ingredients is that the stickiness is severe when using high contents to show high moisturizing effect, which can cause unpleasant feelings. It can be mentioned. These ingredients prevent moisture from evaporating inside the skin, which in turn increases skin moisture. In general, the use of polyhydric alcohols such as glycerin, propylene glycol, 1.3-BG, and sorbitol is lower than oil and wax in terms of moisturizing retention, but is effective in reducing negative effects such as absorption, stickiness, and shine.

In addition, there is a moisturizing using a substance that regulates skin barrier function. Substances that play an important role in enhancing skin barrier function and maintaining skin homeostasis by promoting the expression of ceramides and filaggrins, which play an important role in skin barrier function, such as niacinamide, fall into this category. The most recent spotlight is that it helps to maintain homeostasis and is an approach to the underlying part of moisturizing. However, when the formulation is actually used, it is not only necessary for a long time for the consumer to directly feel moisturizing, but also has a disadvantage in that the effect may be weak, and thus, most of the concept materials are often limited.

Accordingly, the present inventors have studied to solve the above problems, as a result, containing a typical moisturizing glycerin and derivatives thereof, and other PEG. PPG-17. 6 When the cosmetic composition is prepared by containing a copolymer and dipropylene glycol at the same time, a highly moisturizing cosmetic can be prepared with an emolliently shiny, non-sticky, distinctive feeling and a transparent appearance such as those used with oil. The present invention was completed.

Accordingly, it is an object of the present invention to provide a transparent high moisturizing cosmetic composition containing no oil and exhibiting emollient feeling and excellent moisturizing power without stickiness.

In order to achieve the above object, the transparent high moisturizing cosmetic composition according to the present invention (a) one or more selected from the group consisting of glycerin and its derivatives; And (b) PEG. PPG-17. 6 copolymers (copolymer) and at least one selected from the group consisting of dipropylene glycol (dipropylene glycol); characterized in that it contains.

Hereinafter, the present invention will be described in more detail.

Highly moisturizing cosmetic composition according to the present invention (a) one or more selected from the group consisting of glycerin and its derivatives; And (b) PEG. PPG-17. 6 copolymers (dipolymer) and dipropylene glycol (dipropylene glycol) at least one selected from the group; containing a non-sticky emulsified oily feeling and excellent moisture retention.

Glycerin used in the present invention is a colorless transparent sticky liquid made by decomposing fat or oil, which is widely used as a cosmetic raw material, and is a moisturizing ingredient that keeps the skin moisturized. It is characteristic. In particular, the glycerin is a representative moisturizer that shows superior moisturizing power than other polyhydric alcohol moisturizers, and is widely used in foundation products such as lotions and creams, makeup products, soaps, etc., for high moisturizing effect. When it is used alone, stickiness and skin tightness are greatly felt, and in addition to moisturizing effect, it can have a negative effect on the feeling.

Glycereth derivatives are glycerin derivatives, and the raw materials used in the present invention are glycerin derivatives that exclude high-impact elements such as stickiness and tightness while maintaining high moisturizing power and soft and thick feeling of glycerin. PPG. Polybutylene glycol-8. 5. 3 Glycerin. Looking at the characteristics of each of the raw materials, the chemical composition of glycerin (Glycereth) 26 is a polyethylene glycol ether (polyethylene glycol ether) attached to the glycerin, PEG. PPG. Polybutylene glycol-8. 5. 3 Glycerin is a vegetable glycerin alkylene oxide derivative which is planted in fat or oil (triglyceride) having glycerin skeleton in moisturizing oil. Is an excellent raw material and has a significantly lower stickiness compared to the same amount of glycerin. The two raw materials, Glycereth 26 and PEG. PPG. Polybutylene glycol-8. 5. Compared to the three glycerin (glycerin) in terms of overall feeling of use, the glycerin (Glycereth 26) is a bit thicker and has a higher residual feeling.

Highly moisturizing cosmetic composition of the present invention is glycerin and its derivatives (Glycereth) 26 and PEG. PPG. Polybutylene glycol-8. 5. Select one or more selected from the group consisting of 3 glycerin (Glycerin), which contains 5 to 30% by weight based on the total weight of the composition. When the content is less than 5% by weight, it is difficult to exhibit excellent moisturizing power and feeling such as using an emollient, and when the content exceeds 30% by weight, it becomes slightly sticky and feels stuffy. Not suitable

On the other hand, PEG for use in the highly moisturizing cosmetic composition of the present invention. PPG-17. 6 Copolymer and dipropylene glycol are moisturizers popularly used in cosmetics. They are thinner and less moisturizing than glycerin, but they are not sticky due to the somewhat sad feeling. This has the effect of reducing the stickiness when used in conjunction with the raw material exhibiting a sticky feeling. Therefore, in the present invention, using the properties of the two raw materials, while using a high content of the moisturizing agent to prepare a formulation that exhibits a rich feeling of use such as less stickiness and emollient.

Highly moisturizing cosmetic composition of the present invention is PEG. PPG-17. It contains one or more selected from the group consisting of 6 copolymers and dipropylene glycol, which contains 0.5 to 10% by weight based on the total weight of the composition. When the content is less than 0.5% by weight, it is difficult to see the effect of improving the sticky feeling of the negative component of the component (a) when used with the component (a). When the content is more than 10% by weight, the moisturizing power is not greatly increased and the component ( Although less sticky than a) alone, it is not suitable as a cosmetic composition because of the negative factors of frustrating feeling.

The highly moisturizing cosmetic composition according to the present invention contains the component (a) and the component (b) simultaneously, and the ratio of the component (a): component (b) is used in combination by weight ratio of 3: 1 to 10: 1. It is desirable to.

Highly moisturizing cosmetic composition according to the present invention is not particularly limited in the formulation, for example, a cosmetic composition having a formulation of softening longevity, nourishing longevity, massage cream, nutrition cream, pack, gel or skin adhesion type cosmetics Can be.

Hereinafter, the present invention will be described in more detail with reference to Examples and Test Examples. However, the scope of the present invention is not limited only to these examples.

[Examples 1-6 and Comparative Examples 1-5]

In Examples 1 to 6 and Comparative Examples 1 to 5 were prepared in the composition of Table 1. Each moisturizer was mixed with purified water, and then carbomer and triethanolamine were prepared as a thickener to increase the viscosity.

Test Example  1: moisturizing retention  Measurement test

In order to measure the moisturizing retention of the formulations of Examples 1 to 6 and Comparative Examples 1 to 5, the lower portion was applied after applying the formulations of Examples 1 to 6 and Comparative Examples 1 to 5 on the filter on the lid in the apparatus as shown in FIG. Water evaporation inhibitory power was measured by measuring the amount of water evaporated. The reason for evaluating skin moisture suppression is because this item plays the most important role in moisturizing maintenance. In more detail, the test method of measurement was filled with water in a container, covered with a thin film on a lid, and then a sample was uniformly applied on the film, and then the weight change of the container was measured for 24 hours. This experiment attempted to simulate the degree to which each sample inhibited evaporation of water on the skin. At this time, a non-coating group was used as a control, the results are shown in Table 2 below.

Example 1 Example 2 Example 3 Example 4 Example 5 Example 6 Comparative Example 1 Comparative Example 2 Comparative Example 3 Comparative Example 4 Comparative Example 5 Control group Moisture evaporation after 24 hours
(g) 0.8 0.85 0.91 0.9 0.91 0.89 0.83 0.9 0.97 1.1 0.82 2.5

From the results of Table 2, when using a glycerin derivative other than glycerin did not show a significant difference in the amount of water evaporation, used together to improve the feeling of PEG. PPG-17. In the case of 6 copolymer and dipropylene glycol, there was no significant moisturizing effect, but it was slightly moisturizing effect. On the other hand, as in the case of Comparative Example 5, the amount of evaporation of water showed a similar value as in Example 1, but the amount of water evaporated was similar to that of Example 1, but it was difficult to make a transparent formulation due to the appearance of oil. Except for increasing the viscosity by using a large amount of the agent, it was soon separated and showed a tendency to greatly decrease the stability.

Test Example  2 : Feeling  evaluation

The usability of the said Examples 1-6 and Comparative Examples 1-4 was evaluated. The evaluation was carried out as a sensory evaluation of 10 evaluators trained in the evaluation of cosmetic feeling. The evaluation items were sticky items and moisturizing feeling items. The evaluation was sticky evaluation with 1 ~ 5 points. When the stickiness was less, 1 point was scored and many cases were 5 points. The moisturizing evaluation was also evaluated with 1 ~ 5 points. The high case was made 5 points and the low case was made 1 point. After applying each product, the average value of the score of 10 items is shown in Table 3 below.

Example 1 Example 2 Example 3 Example 4 Example 5 Example 6 Comparative Example 1 Comparative Example 2 Comparative Example 3 Comparative Example 4 Sticky 3.8 2.5 2.1 1.88 1.93 1.90 4.95 4.3 4.12 3.9 Moisturizing 4.2 4.8 4.78 4.74 4.68 4.70 4.08 3.4 3.25 2.95

From the results of Table 3, the sticky item was the highest in the case of the comparative example 1 using glycerine alone in the sticky item, when using the glycerin and glycerin derivative alone as can be seen in the results of Examples 1-6 Than PEG. PPG-17. 6 When copolymer and dipropylene glycol were used together, the stickiness score was low and showed a positive result in terms of feeling. In terms of moisturizing, the results of Examples were similar to those of Test Example 1. The result of the comparative example showed the better evaluation. In particular, the results of the moisture evaporation inhibitory power did not differ significantly, but in the moisturizing feeling which is an emotional evaluation, the Example obtained a higher moisturizing feeling than the comparative example. Positively affected by this, and also with PEG. PPG-17. It was found that the use of 6 copolymer and dipropylene glycol together resulted in better results.

[Examples 7-8 and Comparative Examples 6-9]

In Examples 4 to 8 and Comparative Examples 6 to 9 were prepared according to the composition of Table 4. At this time, the component (a) of Table 4 is glycerin (Glycerin), glycerin (Glycereth) 26 and PEG. PPG. Polybutylene glycol-8. 5. 3 Glycerin is mixed at a weight ratio of 1: 1: 1, and component (b) is PEG. PPG-17. 6 copolymer and dipropylene glycol are mixed in a weight ratio of 1: 1. The total content of the component (a) and component (b) is adjusted to 20% by weight based on the total weight of the composition, mixed by varying the ratio of the component (a) and component (b), and then used as a thickener to increase the viscosity. Mer and triethanolamine were used.
