Description

Mousse type sunscreen cosmetic composition by Inorganic UV Filter using inorganic sunscreen

The present invention relates to a mousse-type sunscreen cosmetic composition containing alcohol, oils, surfactants, powders, pigments, propellants and the like. More specifically, the present invention relates to a mousse-type sunscreen cosmetic composition that has a high UV protection index using an inorganic UV blocker and maintains a light feeling that can be used repeatedly, which is an advantage of a mousse type, and a convenient use of a wide area. .

The mousse-type sunscreen products are sprayed with bubbles and can be easily applied to large areas of skin as well as the face. However, due to the nature of the mousse formulation, it was not possible to increase the viscosity much like a general cream or use a combination of organic and inorganic sunscreens. So, we have been trying to increase the UV protection index while maintaining the feeling of using butyl octyl salicylate, film former, silica powder, etc., but the UV protection index is higher than SPF 50 like general cream or lotion type. Sunscreens with an effect with a UVA rating of PA +++ were hard to expect. Therefore, despite the advantages of being lightly repeatable and easily spreading over a wide area, the UV protection index is low, so it cannot be used for leisure sports, so the market for mousse-type sunscreen products is higher than general cream or lotion type sunscreens. Not very active.

[Test Example 1] UV protection index (SPF) measurement, UVA blocking grade (PA) measurement

According to the 'UV Screening Functional Test Method' among the 'Functional Cosmetic Standards and Test Methods' announced by the Korea Food and Drug Administration, the UV protection index was applied by attaching a transparent plastic tape (Transpore Tape; 3M, USA) to the prepared cast and then applying the cosmetic composition to the sample 2 mg. / cm ² , UV protection effect was measured with a UV meter (SPF 290 Analyzer), UVA protection grade PA was measured by the artificial ultraviolet emitter equipped with a 300W xenon arc lamp as a light source Multi-port Solar simulator 601- 300W (Solar Light, USA) was used, and the light intensity was measured using a 3D UV meter (Solar Light, USA) to measure the UV blocking index SPF and ultraviolet for the compositions of Examples 1-6 and Comparative Examples 1-2. A blocking grade PA was measured. The result is shown below. UV protection index was summarized as the average value of three experiments, 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 SPF 51.8 ± 2.3 51.5 ± 3.6 50.6 ± 3.5 50.8 ± 4.2 51.7 ± 2.9 45.4 ± 3.1 51.6 ± 2.5 35.8 ± 2.3 PA +++ +++ +++ +++ +++ ++ +++ ++

As can be seen from the values shown in Table 2, in Comparative Example 2 without using an inorganic sunscreen, it was confirmed that the sunscreen index did not satisfy SPF 50 and PA +++.

[Test Example 2] Measurement of the effect of reducing cloudiness

In order to measure the turbidity of the composition, 0.01 g of each of Examples 1 to 7 and Comparative Examples 1 to 2 were uniformly applied to black artificial leather which can clearly check the cloudiness, and after 1 minute, a color difference meter was applied. Brightness value was measured. The higher the brightness value is, the more white cloud phenomenon occurs. When the difference in brightness value is 1 or more, it is determined that there is a difference in the degree of cloudiness. The results are shown in Table 3 below.

Example 1 Example 2 Example 3 Example 4 Example 5 Example 6 Comparative Example 1 Comparative Example 2 Brightness 15 16 15 16 14 20 17 10

In the results shown in Table 3, the mousse type of Examples 1 to 6 showed almost similar levels compared to the general cream type of Comparative Example 1, but Example 6, which did not use the inorganic pigment, showed relatively heavy turbidity. , Comparative Example 2, in which the inorganic ultraviolet blocker was not used, was markedly less cloudy.

 [Test Example 3] gloss reduction effect that causes shine

In order to measure the gloss index of the composition, 0.01 g of each of Examples 1 to 6 and Comparative Examples 1 to 2 were uniformly applied to black artificial leather that can clearly check the gloss, and then after 1 minute, GARDNER: The gloss value was measured using MICRO-TRI-GLOSS), and the results are shown in Table 4 below.

Example 1 Example 2 Example 3 Example 4 Example 5 Example 6 Comparative Example 1 Comparative Example 2 Glossy Index
(60 degrees) 18 17 17 19 30 18 22 23

From the results of Table 4, the bundling was remarkably high in Example 5 without the silica powder, but in the other Examples 1 to 4 and 6 containing silica, the bundling was compared to Comparative Example 1 prepared in the general cream formulation. This was measured low.

[Test Example 4]

Thirty females aged 25 to 45 years were evaluated for overall satisfaction such as foam forming ability, spreadability, stickiness, and shine for the compositions of Examples 1-6 and Comparative Examples 1-2. Examples 1 to 6 and Comparative Example 2 were squeezed into a mousse-type foam to apply directly to the face face area, Comparative Example 1 was applied to the face face area using the hand, the results are shown in Table 5 Indicated.

Example 1 Example 2 Example 3 Example 4 Example 5 Example 6 Comparative Example 1 Comparative Example 2 Feeling (satisfaction) 5 4 4 4 4 3 5 5

(Criteria) Very bad: 1, Bad: 2, Moderate: 3, Good: 4, Very good: 5

As can be seen from the results shown in Table 5, Example 5 containing no powder was very sticky, and Example 6, which contained no pigment, had relatively low turbidity, resulting in low satisfaction.

As can be seen from the results of the above Test Examples 1 to 4, the present invention contains a water-dispersing inorganic sunscreen in the mousse-type sunscreen cosmetics to satisfy the sunscreen index SPF 50 + PA + + + mousse, By utilizing its advantages, it can be used not only for living UV light but also for outdoor or sports use. In addition to the mousse-type sunscreen cosmetic composition of the present invention can be carried out in a variety of modifications, as long as it does not deviate from the scope of the present invention, all modified embodiments should be included in the scope of the present invention to be interpreted.
