[0047] 2) Ingredients 5 to 9 were added to ingredient 4 and completely dissolved at 50° C.

[0048] 3) The resultant of item 2) was slowly added to the resultant of item 1) with a dropper, and mixed at 150 RPM for 10 minutes.

[0049] In Table, as polyvinylpyrrolidone, ASHLAND's brand name PVP K-30 (molecular weight 40,000˜80,000 g/mol) was used. The same ingredient was used in other preparation examples below.

Experimental Example 1: Evaluation of Makeup Maintaining Ability

[0050] For the compositions of Comparative Examples 1 to 6 and Examples 1 to 4, makeup maintaining ability was evaluated. The makeup maintaining ability on the skin surface was compared relative to the color standard deviation change rate, which is a measure of uniformity after a certain period of time.

[0051] Experiment Method

[0052] 1) After evenly applying a general foundation on the skin surface, the spray type cosmetic composition was separated by 15 cm with a mist pump.

[0053] 2) The composition was evenly sprayed on half of the face (3 times, 0.3 g).

[0054] 3) After 10 minutes, the color standard deviation of the pixels on the left and right sides of the face photographed by the facial photographic analysis system was measured.

[0055] 4) After 4 hours, the color standard deviation of the pixels on the left and right sides of the face photographed by the facial photographing analysis system was measured in the same manner.

[0056] 5) Relative comparison was made by calculating the rate of change of color standard deviation using an equation:

(Rate of change=(Standard deviation of color after 4 hours−Standard deviation of color after 10 minutes)/Standard deviation of color after 10 minutes)

[0057] The results are shown in FIG. 1. It was determined that uniform makeup was maintained as the color standard deviation ratio in the unit area was smaller. Looking at the color standard deviation change rate chart of Comparative Examples 2 to 4, it was confirmed that the higher the PVP content, the lower the color standard deviation change rate, so that the makeup maintaining ability increased. Looking at the color standard deviation change rate chart of Comparative Examples 5 to 6, it was confirmed that the makeup maintaining ability was lowered because the color standard deviation change rate increased when HPS was comprised. In Examples 2 to 4 comprising PVP and HPS at the same time, it was confirmed that the color standard deviation change rate was decreased compared to Comparative Examples 1 to 6, so that the makeup maintaining ability was improved.

[0058] In conclusion, when PVP and HPS were comprised at the same time, a lower change rate of color standard deviation was observed compared to the use of PVP alone and the use of HPS alone. In other words, it was confirmed that the makeup maintaining ability was improved.

Experimental Example 2: Evaluation of Mist Spraying Power

[0059] For the compositions of Comparative Examples 1 to 6 and Examples 1 to 4, the mist spraying power was evaluated. The mist spraying power was compared relative to each other by measuring the spray angle.

[0060] Experiment Method

[0061] 1) After filling the makeup fixing cosmetic composition in a general mist pump container, the sprayed image was photographed and the spray angle was measured.

[0062] The results are shown in FIG. 2. Looking at the spray angle charts of Comparative Examples 2 to 4, it was confirmed that the higher the PVP content, the lower the spray angle, and thus the fine spray power decreased. Looking at the spray angle charts of Comparative Examples 5 to 6, it was confirmed that the fine spraying power was maintained regardless of the HPS content. It was confirmed that Examples 1 to 4 comprising PVP and HPS at the same time increased the spraying angle than Comparative Examples 3 and 4, so that the fine spraying power was increased.

[0063] In conclusion, when the combination of HPS and PVP was used, the spray angle decreased compared to when 1% by weight of PVP was comprised alone. However, when the combination of HPS and PVP was used, the spray angle was superior to that of comprising 2% by weight of PVP. In particular, it was confirmed that when using a combination of HPS and PVP, a level equivalent to about 70 degrees of spray angle that consumers can feel can be achieved.

[0064] However, although the spray angle of Example 4 was slightly lower than that of Example 3, the quality was more excellent in terms of formulation stability and feeling of use.

Experimental Example 3: Evaluation of Stability Over Time

[0065] The composition of Examples 1 to 4 was evaluated for stability over time. The stability over time was confirmed by the sedimentation and redispersion scale.

[0066] Experiment Method

[0067] 1) The spray type cosmetic composition was frozen for 3 days at low temperature (−20° C.), then melted and redispersed.

[0068] 2) The above process was repeated 5 times to visually check the sedimentation and redispersibility.

[0069] The results are shown in Table 2 below. It was confirmed that Examples 1 to 3 comprising 1% by weight of HPS had a relatively lower degree of redispersion than Example 4 containing 0.5% by weight of HPS.

[0070] In conclusion, it was confirmed that the lower the HPS content, the higher the redispersability was.

Preparation Example 2: Preparation of Spray Type Cosmetic Composition

[0071] As a comparative group, spray type cosmetic compositions (Comparative Examples 7 to 10) each including four types of unmodified and modified starch excluding hydroxypropyl starch were prepared in the same process as in Preparation Example 1.

[0072] Experiment Method

[0073] 1) After ingredient 1 (purified water) was heated to 60° C., ingredients 2 to 7 were gradually added and dispersed with a disper for 30 minutes.

[0074] 2) Ingredients 9 to 13 were added to ingredient 8 and completely dissolved at 50° C.

[0075] 3) The resultant of item 2) was slowly added to the resultant of item 1) with a dropper, lit and mixed at 150 RPM for 10 minutes.

Experimental Example 4: Starch Stability Evaluation

[0076] 100 mL of the prepared Comparative Examples and Example were allowed to stand at room temperature for 48 hours to confirm the presence or absence of sedimentation.

[0077] As a result, it was confirmed that the four types of unmodified and modified starch other than hydroxypropyl starch have poor dispersion stability because sedimentation occurs (Table 4 and FIG. 3).
