This application claims the benefit of the filing date of Korean Patent Application No. 10-2014-0020510 filed with the Korean Intellectual Property Office on February 21, 2014, the entire contents of which are incorporated herein.

The cosmetic composition of the mousse is sprayed in the form of foam, so that it can be easily applied to a large area of the skin as well as the face, and the use is light, so when applied to a sunscreen product, the application is easy and repeated use is convenient. However, due to the nature of the mousse formulation, a surfactant is essentially included in the formulation for mixing the contents and the gas in order to foam and retain the foam, but the composition containing the surfactant has a weak durability for water or sweat, It can be used only for daily use and its use is limited for leisure and sports.

In order to solve the above problems, a composition has been disclosed that enhances water resistance without using a surfactant. However, while the water resistance is improved by not using a surfactant, there is still a problem that the form and holding power of the foam are inferior to cosmetic products of mousse type such as hair mousse.

Accordingly, the present inventors have properly combined the wax type and the thickener with the oil having good volatility without using a surfactant, thereby significantly improving the foam form and the foam holding power, thereby completing a composition having excellent usability and ease of application.

Accordingly, an object of the present invention is to provide a mousse-type sunscreen cosmetic composition having a high UV protection index and water resistance and excellent bubbleability.

In order to achieve the above object, the present invention is at least one silicone oil; Two or more waxes; And it provides a mousse-type cosmetic composition comprising at least two kinds of thickeners.

In addition, the present invention provides a sunscreen use of the mousse-type cosmetic composition, and provides a method of blocking ultraviolet rays by applying the mousse-type cosmetic composition to the skin.

The mousse-type sunscreen cosmetic composition provided by the present invention maintains a UV protection index of SPF50 or more and a UVA protection rating of PA +++, while being easy to use repeatedly with a light feeling, and is a mousse type having excellent foaming power. It can be applied easily. In addition, it is resistant to sweat and water because of its water resistance, so it can be used not only for daily use but also for leisure sports.

In addition, the silicone oil is used in an amount of 3 to 6% by weight or less based on the total weight of the composition, and preferably may be used in an amount of 5 to 6% by weight. If the content is less than 3% by weight, the density of the foam is lowered, and if the content is more than 6% by weight, it is not preferable because there is a problem in formulation stability.

Wax in the present invention is used to enhance the water resistance, stabilize the organic sunscreen and inorganic sunscreen in the composition to provide a higher sunscreen effect and to maintain the form of the foam. As the wax, at least two selected from fatty alcohol waxes behenyl alcohol, stearyl alcohol, cetyl alcohol and cetearyl alcohol, and fatty acid waxes stearic acid and palmitic acid are used. If only one type of fatty acid wax is used, there is a problem in the stability of the formulation.

In addition, the measurement of UVA blocking grade PA was performed using an artificial ultraviolet emitter Multi-port Solar simulator 601-300W (Solar Light, USA) equipped with a 300W xenon arc lamp as a light source. Solar Light, USA) was used to measure the light intensity to determine the UVA blocking grade PA for the composition of Example 12 and Comparative Example 10. UV protection index was summarized as the average value of three experiments, the results are shown in Table 8 below.

Table 8

	Example 12	Comparative Example 10
SPF	79.2 ± 10.1	54.3 ± 5.5
PA	+++	+++

As shown in Table 8, in the case of the composition according to the present invention, it can be seen that the sunscreen index can be maintained at a higher level even if the same amount of sunscreen is included.

Test Example 6 Water Resistance Effect

To the artificial skin testing substrate (trade name: Vitro Skin, manufactured by IMS Testing group) at 2 mg / cm ² , the compositions of Example 12 and Comparative Example 1 were respectively applied, and were subjected to UV protection ability (SPF _dry ) and immersion in a dry state. After the loss of the sunscreen by the sun, after immersion, the sun protection capacity (SPF _wet ) was measured.

Comparing the SPF _dry and SPF _wet to calculate the water resistance (water resistance) of the composition of Example 12 and Comparative Example 1 according to the following equation 1 shown in Table 9 below.

[Equation 1]

% Resistance = {(SPF _dry -1) / (SPF _wet -1)} X 100

The SPF _dry , SPF _wet and water resistance are SPF measurement method using the in vitro water resistance SPF measurement system and theory of the sunscreen of Korea Patent Publication No. 2006-0038518 and published in IFSCC "Alternative evaluation method in vitro for water resistant It was measured and calculated by the method described in "effect of sunscreen products".

Table 9

	Example 12	Comparative Example 10
Water resistance (%)	78	52

As shown in Table 9, the composition according to the present invention is excellent in water resistance, it can be seen that it can be kept long without being easily erased by sweat or water.
