Description

Mist cosmetic composition of Jelly type

The present invention relates to a mist cosmetic composition embodying a jelly-type oil-in-water (O/W) tone-up cream formulation containing an acrylate/behenes-25 methacrylate copolymer, silica and titanium dioxide.

Tone-up cream is a cream that instantly brightens the skin tone. Tone-up cream is a type of whitening cream, but it is different from the existing concept. Existing whitening cream is a basic product, and when applied continuously for a long period of time, the skin tone is gradually improved. However, tone-up cream is mainly used as a substitute for make-up, and as soon as it is applied, the skin tone is immediately brightened, and it has the advantage that it can be used as a basic product.

Since these tone-up creams are usually prepared using moisturizers, thickeners, emulsifiers and high-grade alcohols, they often run off when applied. In addition, due to the characteristics of the formulation, it is often spilled around when used. In particular, after applying the tone-up cream to the skin, if you wear clothes or come in contact with other places, stains will appear.

Tone-up cream formulation in a general sense is a general emulsifier type containing titanium oxides that have a tone-up function, and it is generally used in a tube or pump. First, take a certain amount of tone-up cream on your hand and then apply it to the desired area. In this case, there is a disadvantage in that it is buried on the hand or around the hand when in use.

Therefore, there is a demand for the development of a jelly-type mist cosmetic composition that does not run down while performing an immediate tone-up function, and does not stain or leave after application.

Accordingly, the present inventors tried to make a mist cosmetic composition that has an immediate tone-up effect, no dripping, no stains and no smudges after application by mixing appropriate raw materials for moisturizing agents, thickeners, high alcohols, emulsifiers, preservatives, silicone and sunscreen. .

In particular, through the development of a jelly-type cosmetic composition, it was applied in a mist formulation for immediate tone-up, and then the function of not staining white was maximized.

Accordingly, it is an object of the present invention to provide a mist cosmetic composition embodying a jelly-type oil-in-water (O/W) tone-up cream formulation containing acrylate/behenes-25 methacrylate copolymer, silica and titanium dioxide. .

The present invention relates to a mist cosmetic composition embodying a jelly-type oil-in-water (O/W) tone-up cream formulation containing acrylate/behenes-25 methacrylate copolymer, silica and titanium dioxide, and the present inventors By mixing LATE/BEHENES-25 methacrylate copolymer, silica and titanium dioxide at an appropriate mixing ratio, a jelly-type tone-up mist cosmetic composition formulation can be implemented to provide an immediate tone-up effect, and it is superior to the existing tone-up cream. It was confirmed that the effect of not dripping and less staining and smearing after application was excellent.

After weighing each raw material in a beaker according to each component and content described in Table 1, the aqueous phase part was uniformly stirred for 3 minutes at 7000 rpm using a homo mixer at a temperature of 75 to 80 °C. Then, a thickener was added at the same temperature to the aqueous phase part after the stirring step, followed by uniform stirring at 7000 rpm for 5 minutes. Then, the oil phase separately heated at a temperature of 70° C. was added, followed by uniform stirring at 7000 rpm for 5 minutes. Then, after cooling to 45 °C, a preservative was added and the mixture was uniformly stirred at 7000 rpm for 3 minutes. Then, after cooling to 30 ℃, the bubbles were removed to prepare the cosmetic compositions of Comparative Examples 1 to 4.

As shown in FIG. 2, Comparative Example 1 showed a lot of smearing immediately after use, and Comparative Example 2 was not fixed during spraying and the liquid flowed down, so it was confirmed that it did not have a jelly type. In addition, in the case of Comparative Example 3, the viscosity was too high, so it was not sprayed from the spray pump, and Comparative Example 4 had less dripping compared to other Comparative Examples, but it was blotted out immediately after use, and the tone-up effect was insufficient. .

Experimental Example 1. Observation of change in formulation of cosmetic composition

Changes in the formulation of the mist cosmetic composition prepared in Preparation Example of the present invention were observed, and the results are shown in Table 3 below.

Example 1 Example 2 Comparative Example 1 Comparative Example 2 Comparative Example 3 Comparative Example 4 1 day stability stability stability stability stability stability 7 days stability stability stability stability stability stability 14 days stability stability stability stability stability stability 1 month stability stability stability separation discoloration stability

As shown in Table 3, as a result of observing the stability of the cosmetic composition formulation at room temperature for 1 month, Examples 1, 2 and Comparative Example 1 were stable even after 1 month after preparation.

On the other hand, in Comparative Example 2, separation was observed after one month. The reason for the separation phenomenon in Comparative Example 2 is that the content of the acrylate behenes-25 methacrylate copolymer was less than the appropriate amount. In addition, the cosmetic composition formulation of Comparative Example 3 was also discolored. This is because Comparative Example 3 contained more acrylate behenes-25 methacrylate copolymer than an appropriate amount.

In contrast, Comparative Example 4 containing the same amount of acrylate beheneth-25 methacrylate copolymer and silica as in Example 1 showed that the cosmetic composition was stable in stability. This means that the content ratio of acrylate behenes-25 methacrylate copolymer and silica plays an important role in maintaining the formulation of the cosmetic composition.

Experimental Example 2. Sensory evaluation

After dividing into two groups for 21 professional panelists aged 20 to 50, Examples 1 and 2 and Comparative Examples 1 to 4 were used on the forearm area, and spreadability, nutrition, and smearing felt when applied according to the following evaluation criteria The feeling of use such as degree, dripping and overall satisfaction was evaluated, and the results are shown in Table 4 below.

Among the criteria, spreadability means the feeling that the cosmetic composition is spread on the skin. Nutrition refers to the feeling of giving moisture to the skin when applied to the skin. The degree of smearing refers to the degree to which the composition is applied to the skin surface in an appropriate amount when applied to the skin, and when it comes into contact with other places immediately after being applied to the skin. The degree of dripping refers to the degree of dripping from the skin when applied to the skin with a spray. These four criteria increase the value of use as a cosmetic, and in particular, smearing and dripping can be important characteristics of the present technology.

<Evaluation criteria>

More than 20 women judged to be excellent: ◎

11-19 women judged to be excellent: ○

6-10 women judged to be excellent: △

No more than 5 women judged to be excellent: X

Example 1 Example 2 Comparative Example 1 Comparative Example 2 Comparative Example 3 Comparative Example 4 spreadability ◎ ○ △ △ X ○ nutrition ◎ △ △ △ △ △ buried ○ ○ X △ △ △ drip ○ ○ ○ X X ○ overall satisfaction ◎ ○ △ △ X △

As can be seen in Table 4, it was found that Example 1 was superior to Examples 2 and Comparative Examples 1 to 4 in overall satisfaction such as spreadability, nutritional feeling, smearing and dripping. In particular, Example 1, which has a jelly-type formulation and plays a role of tone-up (appliedness, smearing, dripping), was found to have the best overall feeling.

Comparative Example 1 received poor evaluation in terms of spreadability and smearing. The reason is that Comparative Example 1 contains about 5 times the content of titanium dioxide, which is a physical sunscreen, than Example 1. Titanium dioxide as a physical sunscreen has the disadvantage of causing cloudiness and stiff application if the amount used is large. In addition, Comparative Example 1 does not contain silica, but the silica serves to prevent contamination of the formulation as a film former in implementing the cosmetic formulation.

Comparative Example 2 received an overall poor evaluation in terms of feeling of use. In particular, it received the worst evaluation for dripping, and Comparative Example 2 contained about 0.55 times less acrylate beheneth-25 methacrylate copolymer than Example 1. The content of acrylate beheneth-25 methacrylate copolymer is important in implementing the jelly-type formulation, and if it is out of the optimal content ratio, the jelly-type formulation may not be realized and may flow down.

Comparative Example 3 also received the worst overall evaluation. In particular, it received the worst evaluation for spreadability and dripping, and Comparative Example 3 has an acrylate beheneth-25 methacrylate copolymer content of about 1.46 times higher than that of Example 1 compared to Example 1. If the amount of thickener is increased, the feeling of use may deteriorate, such as stiff and sticky. Accordingly, the content of the emulsifier palmitic acid was increased by about 3.33 times or more to improve the feeling of use while increasing the content of the acrylate behenes-25 methacrylate copolymer as a thickener, but It did not improve the spreadability and dripping.

Comparative Example 4 received an overall good evaluation. Compared with Example 1, Comparative Example 4 contained half of the titanium dioxide content than Example 1. When the titanium dioxide content is included more than the reference value, it may cause cloudiness and stiff application, whereas when it is included in a small amount, it does not affect the spreadability, but overall satisfaction may be lowered due to a decrease in nutrition or smearing.

Experimental Example 3. Evaluation of skin brightness before/after product use

The cosmetic composition was applied to the skin and the ITA (Individual Typology Angle) VALUE was compared to evaluate the brightness of the skin. ITA VALUE is a value calculated by substituting the skin's brightness (L VALUE) and yellowness (b VALUE) into a constant formula.

[formula]

ITA VALUE = {ATAN(L VALUE *-50)/b VALUE* X 180/3.14159

The results of evaluating skin brightness in the same manner as above are shown in Table 5 and FIG. 3 .

ITA value Former (Unit: °) After (unit: °) Example 1 38.9 53.2 Example 2 38.9 50 Comparative Example 1 38.9 46 Comparative Example 2 38.9 48 Comparative Example 3 38.9 28 Comparative Example 4 38.9 30

As can be seen in FIG. 3 , in the case of Example 1, when comparing before and after the ITA VALUE measurement, it is confirmed that the ITA VALUE increased the most from 38.9 to 53.2. Example 2 Fig. 38.9 increased to 50. On the other hand, it was confirmed that Comparative Examples 1 and 2 increased skin brightness less than that of Example. In addition, in Comparative Examples 3 and 4, it was confirmed that the skin brightness decreased after the measurement rather than before the measurement.

Through this, it was confirmed that Examples 1 and 2 including the titanium dioxide component in a certain content ratio exhibit the most excellent effect in increasing skin brightness.

Experimental Example 4. Evaluation of moisturizing power using a moisture meter

Moisture power test was performed using a moisture meter (Corneometer, CK electronic, Germany). Specifically, the test site (inner arm, 2 cm X 2 cm) was washed with lukewarm water 30 minutes before the test. Then, after waiting in a constant temperature and humidity room (22° C., humidity 40 to 60%) for 10 minutes, the moisture content of the skin was measured when the test site was not applied. Then, 8 mL of each sample was spread evenly on the test site for absorption. Then, the moisture content of the skin 2 hours, 4 hours, and 8 hours after the diagram was measured three times, respectively. As for the result analysis method, the change rate of the skin moisture level was calculated using the average of three measurements, and then compared with the value before use, and the results are shown in FIGS. 4 and 6 .

Skin Moisture (%) Example 1 119 Example 2 79 Comparative Example 1 102 Comparative Example 2 108 Comparative Example 3 96 Comparative Example 4 89

As can be seen in FIGS. 4 and 6, in the case of Example 1, it was confirmed that the skin moisture content increased by about 119% from immediately after application to 8 hours compared to that of no application.

On the other hand, Example 2 contains 1 wt% of Queensland nut oil, which is 50% compared to Example 1. It can be confirmed that Queensland nut oil affects moisture and the moisture content is lowered as the content is lowered.

Comparative Examples 1 and 2 increased about 105% when averaged for 8 hours of moisturizing, so that compared to Comparative Examples 3 and 4, which increased by about 92.5, the product had a moisturizing power. However, it was confirmed that the product of Example 1 showing the highest value among the manufactured cosmetic compositions had the best moisturizing power.
