Description

[0001] The present invention relates to a cosmetic composition for improving skin moisturization,

The present invention relates to a cosmetic composition for improving skin moisturizing, and more particularly, to a cosmetic composition containing a large amount of a polyol as a moisturizing ingredient to maximize skin moisturizing effect and to improve sticky and stiff feeling using polyethylene glycol additive oil as a solubilizer and conditioning agent To a cosmetic composition.

In general, the most common way to implement high-moisturizing cosmetics is to control the ingredients of emulsions in the emulsifier type or to use a large amount of the moisturizing polyol.

First, high moisture can be exhibited by controlling the content of oil or wax contained in the oil phase. However, there is a problem that the absorption is slowed by the emulsifier and the feeling of use of negative effects such as stickiness or shine is likely to appear.

Another method is to contain a large amount of polyols such as glycerin, propylene glycol and the like which are the most commonly known moisturizing ingredients. Such a polyol component forms a moisturizing film on the surface of the skin to maintain the moisture of the skin to maintain the moisturizing effect for a long time. However, when a large amount of polyol is contained, there is a problem of a thick feeling and a high moisturizing effect, but it is very sticky and too absorbed so that it does not give a massage feeling, and there is a problem of forming a non-smooth film on the skin after absorption. It may also be irritating depending on the solubilizing agent used.

Therefore, it is urgent to develop a cosmetic composition which is improved in feeling of use such as stickiness and stiffness while maintaining the moisture resistance as compared with the conventional cosmetic composition for skin moisturization improvement.

Turbidity (NTU) 0.910 0.907 41.5 56.6

As can be seen from the above Table 1, it was confirmed that there is a significant difference in transparency according to the content of polyol in the whole composition. In Examples 1-1 and 1-2, the letters on the back of the container were clearly visible, whereas in Comparative Examples 1-1 and 1-2, the letters were blurred and the transparency was lowered. In particular, the transparency was excellent in Example 1-1 using olive oil PEG-7 ester. From this, it was found that the content of polyol affects the transparency of the cosmetic composition.

Also, in addition to the visual evaluation method, the transparency difference could be compared using a turbidity meter (HACH 2100AN Turbidimeter). The transparency determined by the turbidity meter means that the turbidity value is closer to 0 and the light is scattered less transparently. The larger the turbidity value, the more opaque the light is scattered. As shown in Table 2, the results of Examples 1-1 and 1-2 are lower than 1 NTU, and that of Comparative Examples 1-1 and 1-2 is much higher than that of Examples.

Example  2-1 to 2-2 and Comparative Example  2-1.

The cosmetic compositions according to Example 2-1 and Comparative Example 2-2 were applied to the back of the hand, kneaded and absorbed, and the effect of improving the stickiness was examined by confirming the degree of adhesion of the paper when a small-sized paper was attached. The results are shown in Table 6 below.

Example 2-1 Comparative Example 2-2

As can be seen from Table 6, in Example 2-1 using olive oil PEG-7 ester as a solubilizing agent, it was confirmed that the number of papers sticking to Comparative Example 2-2 is significantly smaller than that of Comparative Example 2-2. Thus, by using the polyethylene glycol addition oil according to the present invention as a solubilizer, it is possible to provide a cosmetic improved in stickiness.

2) Sensory evaluation confirmation

Sensory evaluations were conducted on Examples 2-1 and 2-2 in order to confirm the massage feeling according to the absorption rate. The evaluation of the massage feeling according to the absorption rate was performed on five unmarried and married women between 20 and 45 years old and subjected to sensory evaluation according to the following evaluation criteria. The sensory evaluation was performed by applying the cosmetic compositions of Example 2-1 and Comparative Example 2-2 to the subject's body, respectively, and then evaluated the absorption rate of the cosmetic composition, the satisfaction with the sensation of massage, and the massage sensation time experienced by the subject . The results are shown in Table 7 below.

<Evaluation Criteria-Absorption Rate and Massage Sensing Time>

5 points: Very fast / Very satisfied

4 points: Fast / Satisfied

3 points: Average

2 points: slow / deficient

1 point: very slow / very short
