Here, the term "leave-on" means that the compositions according to the present invention are not removed from the keratinous substances after being applied to the keratinous substances. Here, the term "rinse-off" means that the compositions according to the present invention are removed from the keratinous substances by rinsing after being applied to the keratinous substances. Water can be used for rinsing. Even after rinsing, the compositions according to the present invention can remain to form a film or coating on the keratinous substances such as the skin.

[0298] The present invention also relates to:

[0299] A cosmetic method for a keratinous substrate such as the skin, the cosmetic method comprising applying the composition according to the present invention to the keratinous substrate.

[0300] The cosmetic method herein refers to a non-therapeutic cosmetic method for caring for and / or making up the surface of a keratinous substrate such as the skin.

[0301] Since the composition according to the invention comprises (a) an inorganic UV filter and (b) an organic UV filter, this cosmetic method can protect keratinous substrates such as the skin from UV rays, thereby limiting the darkening of the skin, improving the color and uniformity of the skin tone, and / or treating the aging of the skin.

[0302] The invention also relates to:

[0303] The use of (b) at least one organic UV filter selected from organosilicon compounds having at least one benzotriazole group in a composition, wherein the composition comprises (a) at least one inorganic UV filter in an amount greater than 5% by weight relative to the total weight of the composition,

[0304] to improve the smooth texture of the composition.

[0305] The use according to the invention can reduce the astringent feeling caused by the relatively large amount of (a) inorganic UV filter in the composition.

[0306] The use according to the invention can provide an improved smooth texture during the application of the composition to keratinous materials such as the skin.

[0307] The use according to the invention can even provide an improved smooth texture after washing off the composition from keratinous materials such as the skin.

[0308] The description regarding components (a) to (d) of the composition according to the invention is applicable to those in the use according to the invention. Examples

[0309] The invention will be described in more detail by way of examples. However, they should not be construed as limiting the scope of the invention.

[0310] [Examples 1 - 6 and Comparative Examples 1 - 27]

[0311] [Preparation]

[0312] The compositions according to Examples 1 - 6 and Comparative Examples 1 - 27 were prepared by mixing the components shown in Tables 1 - 4 at room temperature (25 °C). The numerical values of the amounts of the components in Tables 1 - 4 are all based on "weight %" as the raw materials.

[0319]

[0320] [Evaluation]

[0321] (In vitro SPF)

[0322] Each composition according to Examples 1-6 and Comparative Examples 1-27 will be applied to a PMMA (polymethyl methacrylate) plate at 25 °C in an amount of 1.3 mg / cm 2 . After drying each composition, the UV absorption spectrum of the composition is measured using an SPF analyzer (UV-2000S), and its in vitro SPF value is calculated from the UVB absorption intensity measured by the SPF analyzer.

[0323] The results are shown in Tables 1-4.

[0324] (In vitro PPD)

[0325] Each composition according to Examples 1-6 and Comparative Examples 1-27 will be applied to a PMMA (polymethyl methacrylate) plate at 25 °C in an amount of 1.3 mg / cm 2 . After drying each composition, the UV absorption spectrum of the composition is measured using an SPF analyzer (UV-2000S), and its in vitro PPD (persistent pigment darkening) value is calculated from the UVA absorption / UVB absorption ratio based on the UVA absorption and UVB absorption measured by the SPF analyzer.

[0326] The results are shown in Tables 1-4.

[0327] (Smoothness during application)

[0328] Each composition according to Examples 1-6 and Comparative Examples 1-27 will be applied to the underarms of 3 experts by finger in an amount of 2 mg / cm 2 . The panel members evaluate the smoothness during application on a scale of 1 (very rough = astringent) to 5 (very smooth), and the scores of the scale are averaged.

[0329] The results are shown in Tables 1-4.

[0330] (Smoothness after washing off)

[0331] Each composition according to Examples 1-6 and Comparative Examples 1-27 will be applied to the underarms of 3 experts by finger in an amount of 2 mg / cm 2An amount of 100% was applied to the underarms of 3 experts with fingers. The panelists rated the smoothness of the composition after rinsing off with tap water on a scale of 2 (very rough = scratchy) to 5 (very smooth), and averaged the scores of the scale.

[0332] The results are shown in Tables 1-4.

[0333] (stability)

[0334] After storage at 4° C. for 1 month from the preparation of the compositions according to Examples 1 to 6 and Comparative Examples 1 to 27, each composition was subjected to microscopic observation to examine the crystallization of the organic UV filter.

[0335] Specifically, a small droplet of each composition according to Examples 1 to 6 and Comparative Examples 1 to 27 was placed on a transparent glass plate and covered with a cover glass, and was observed with a polarizing microscope (Olympus BX51).

[0336] If no crystals are found, the assessment is good.

[0337] If any crystals were found, the assessment was poor.

[0338] The results are shown in Tables 1-4.

[0339] (Summary)

[0340] The compositions according to Examples 1 to 6 can provide adequate UV protection with respect to both UVA and UVB as well as a smooth feel during application and after washing off, even though they comprise relatively large amounts of TiO2 as (a) inorganic UV filter.

[0341] Furthermore, the compositions according to Examples 1 to 6 were stable, so that no crystals of drometrizole trisiloxane as the (b) organic UV filter were found therein.

[0342] The composition according to Comparative Example 1 did not include drometrizole trisiloxane, and therefore, the UV protection of the composition was insufficient, and its smoothness was not good.

[0343] The composition according to Comparative Example 2 does not include TiO2, and therefore, the UV protection of the composition is insufficient.

[0344] The composition according to Comparative Example 3 contained less than 5 wt % of TiO 2 , and therefore, the UV protection of the composition was insufficient.

[0345] The composition according to Comparative Examples 4-27 does not include drometrizole trisiloxane, and therefore, the smoothness thereof during application or after washing off is not good, or the UV protection of the composition (particularly against UVA) is insufficient.

[0346] [Examples 7 - 11]

[0347] [Preparation]

[0348] Each composition according to Examples 7 - 11 was prepared by mixing the ingredients shown in Table 5 at room temperature (25 °C). The numerical values of the amounts of the ingredients in Table 5 are all based on "wt%" as the raw materials.

[0349]

[0350]

[0351] [Evaluation]

[0352] (Emulsion stability)

[0353] Two months after storage at 45 °C from the preparation of the compositions according to Examples 7 - 11, each composition was subjected to visual observation.

[0354] Specifically, 40 g of each composition according to Examples 7 - 11 was filled into a transparent glass bottle and stored at 45 °C for two months. The appearance of the transparent glass bottle was visually observed.

[0355] If no change was observed, it was evaluated as good.

[0356] If a slight color change or slight phase separation (e.g., floating oil on the top) was found, it was evaluated as fair.

[0357] If a color change or phase separation was found, it was evaluated as poor.

[0358] The results are shown in Table 5.

[0359] (Summary)

[0360] The compositions according to Examples 7, 8 and 10 were more stable, while the compositions according to Examples 9 and 11 that did not contain isopropyl myristate or potassium cetyl phosphate were less stable.

[0361] Therefore, it is preferred that the composition containing TiO2 and cresotriazone trisiloxane further contains (c) a fatty material such as isopropyl myristate and / or (d) a phosphate / salt compound such as potassium cetyl phosphate.
