Description

Spray type cosmetic composition having makeup holding power and spraying power

The present invention relates to a spray type cosmetic composition having excellent makeup holding power and spraying power at the same time. More specifically, the present invention relates to a fixer cosmetic composition used after application of makeup cosmetics, and particularly to a fixer cosmetic composition in a mist formulation.

A film forming agent used in cosmetics is a polymeric compound mainly in the form of a polymer, and serves to form a flexible, durable, and adherent film film on the surface of skin or hair.

Films with different properties can be formed by various synthesis or reaction processes of film forming agents. Film forming agents are mainly used in color eye makeup cosmetics (Korean Patent Publication No. 10-2019-0002810), wrinkle improvement (Korean Registered Patent Publication No. 10-1714598), and peel-off packs (Korean Patent Publication No. 10-1714598). 10-1716475), etc., and is also used in basic cosmetics. However, the film-forming agent has the disadvantage of being sticky and reducing the spraying power as the amount of the film-forming agent increases.

On the other hand, among basic cosmetics, mist is classified as a leave-on cosmetics that is sprayed on the skin surface and remains on a wide area.

Among these mist cosmetics, a fixer that is used after color makeup to increase makeup durability has been released.

Spraying power and makeup holding power are important factors in a makeup fixer, but since it is difficult to simultaneously satisfy these two, research is needed to solve these problems.

The problem to be solved by the present invention is to provide a cosmetic composition in the form of a spray that has excellent makeup holding power (fixation and / or sustaining power) and spraying power at the same time, while having less stickiness.

Another problem to be solved by the present invention is to provide a cosmetic composition that is a spray formulation such as a mist formulation and has excellent makeup holding power and spraying power at the same time as a cosmetic composition for use as a makeup fixer.

The inventors of the present invention tried to develop a spray-type cosmetic composition containing a film former to increase makeup fixation and durability, but with less stickiness and excellent spraying power.

To this end, a composition was prepared using polyvinylpyrrolidone having excellent adhesion. Polyvinylpyrrolidone has the advantage of excellent makeup durability compared to other film formers. However, as the content of polyvinylpyrrolidone increases in order to increase makeup fixing power and durability, there is a disadvantage in that it is sticky and the spraying power decreases.

In order to overcome the above problems caused by polyvinylpyrrolidone, the inventors of the present invention added various starch materials to the composition. Starch means starch polymer. Starch is an amphiphilic substance that absorbs and absorbs oil at the same time and has a film-forming function. Starch includes hydroxypropyl starch phosphate, acetylated corn starch, and acetylated rice starch that have undergone various modifications or synthesis processes to increase solubility.

As a result of the inventors' confirmation, when hydroxypropyl starch, among starch materials, is contained in a fixer composition together with polyvinylpyrrolidone, while maintaining the advantages of the polyvinylpyrrolidone (that is, while maintaining makeup fixing power and durability) , the decrease in blowing force, which is a disadvantage of polyvinylpyrrolidone, was insignificant, and at the same time, it was not sticky.

Not all starch materials showed the above effect, and only hydroxypropyl starch was suitable for the intended use. In particular, in the case of using general unmodified starch and modified starch other than hydroxypropyl starch, poor results were shown in terms of sedimentation stability of the formulation.

That is, the inventors of the present invention solved the limitations of low makeup durability, low mist spraying power, or stickiness when using polyvinylpyrrolidone and hydroxypropyl starch alone, and polyvinylpyrrolidone and hydroxypropyl star By combining the above, the present invention was completed by confirming that the makeup fixation and durability of polyvinylpyrrolidone and the advantages of spraying power and low stickiness of hydroxypropyl starch can be maintained at the same time (without affecting each other in a negative direction) .

In Table 1, ASHLAND's trade name PVP K-30 (molecular weight 40,000 to 80,000 g/mol) was used as polyvinylpyrrolidone. The same raw materials were used in other production examples below.

Experimental Example 1: Evaluation of makeup retention

For the compositions of Comparative Examples 1 to 6 and Examples 1 to 4, the makeup holding power on the skin surface was compared by measuring the color standard deviation change rate, which is a uniformity measure after a certain period of time.

Experiment method

1) After applying the general-purpose foundation evenly on the skin surface, the spray type cosmetic composition is spaced 15 cm apart with a mist pump.

2) Spray the same amount (3 times, 0.3g) evenly on the half of the face.

3) After 10 minutes, measure the pixel color standard deviation of the left and right sides of the face taken by the facial facial imaging analysis system.

4) After 4 hours, measure the pixel color standard deviation of the left and right sides of the face photographed with the same facial facial imaging analysis system.

5) Calculate the color standard deviation change rate using the formula and perform relative comparison.

6) (rate of change = (color standard deviation after 4 hours - color standard deviation after 10 minutes) / color standard deviation after 10 minutes)

The results are shown in Figure 1. It was judged that the uniform makeup was maintained as the color standard deviation rate within the unit area was smaller. Looking at the color standard deviation change rate charts of Comparative Examples 2 to 4, it was confirmed that the higher the PVP content, the higher the makeup retention because the color standard deviation change rate decreased. Looking at the color standard deviation change rate charts of Comparative Examples 5 and 6, it was confirmed that the makeup retention was lowered because the color standard deviation change rate increased when HPS was contained. In Examples 2 to 4 containing PVP and HPS simultaneously, it was confirmed that the makeup holding power was increased because the color standard deviation change rate was reduced compared to Comparative Examples 1 to 6.

In conclusion, in the case of including PVP and HPS at the same time, a lower color standard deviation change rate was observed compared to the case of using PVP alone and compared to the case of using HPS alone. That is, it was confirmed that the makeup holding power was improved.

Experimental Example 2: Evaluation of mist spraying ability

For the compositions of Comparative Examples 1 to 6 and Examples 1 to 4, the mist spraying ability was compared relative to the spray angle measurement.

Experiment method

1) Measure the spray angle by taking a sprayed image after filling the makeup fixing cosmetic composition into a general-purpose mist pump container.

The results are shown in FIG. 2 . Looking at the spray angle charts of Comparative Examples 2 to 4, it was confirmed that the spray angle decreased as the PVP content increased, thereby reducing the fine spraying ability. Looking at the spray angle charts of Comparative Examples 5 and 6, it was confirmed that the fine spraying ability was maintained regardless of the HPS content. Examples 1 to 4 containing PVP and HPS at the same time had an increased spray angle than Comparative Examples 3 and 4, which did not contain it, so it was confirmed that the fine spraying ability was increased.

In conclusion, when using the combination of HPS and PVP, the spray angle was reduced compared to when 1 wt% of PVP alone was included, but the spray angle was better than when 2 wt% of PVP was included. In particular, when using the combination of HPS and PVP, it was confirmed that a level equivalent to the spray angle of about 70 degrees that consumers can experience can be achieved.

However, although the spray angle of Example 4 was slightly lower than that of Example 3, the quality in terms of formulation stability and feeling of use was more excellent.

Experimental Example 3: Evaluation of stability over time

For the compositions of Examples 1 to 4, stability over time was confirmed on the scale of sedimentation and redispersion.

Experiment method

1) The spray type cosmetic composition is frozen at low temperature (-20℃) for 3 days, then melted and redispersed.

2) Repeat the above process 5 times to check the sedimentation and redispersion ability with the naked eye.

The results are shown in Table 2. It was confirmed that Examples 1 to 3 containing 1% by weight of HPS had a lower relative degree of redispersion than Example 4 containing 0.5% by weight of HPS.

In conclusion, it was confirmed that the lower the HPS content, the higher the redispersibility.

Preparation Example 2: Preparation of spray type cosmetic composition

As a comparative group, propellant-type cosmetic compositions (Comparative Examples 7 to 10) containing four unmodified and modified starches, respectively, except for hydroxypropyl starch, were prepared by the same process as in Preparation Example 1.

Experiment method

1) After heating raw material 1 (purified water) to 60 ° C, raw materials 2 to 7 were gradually added and dispersed with a disper for 30 minutes.

2) Raw materials 9 to 13 were added to raw material 8 and completely dissolved at 50℃.

3) The material of item 2) was slowly added to the material of item 1) with a spout and mixed at 150 RPM for 10 minutes.
