[0003] However, it has been found that when the composition contains a relatively large amount of an inorganic UV filter, such as TiO2, the composition tends to result in a squeaky texture. [Prior art documents] [Patent documents]

[0206] The use according to the invention may also result in an improved smooth texture, even after rinsing the composition from keratinous materials such as the skin.

[0207] The explanations regarding components (a) to (d) of the composition according to the present invention are applicable to the explanations of the uses according to the present invention. EXAMPLES

[0208] The present invention will now be described in more detail by means of examples, which should not, however, be construed as limiting the scope of the present invention.

[0209] (Examples 1 to 6 and Comparative Examples 1 to 27) [Preparation] Each of the compositions according to Examples 1 to 6 and Comparative Examples 1 to 27 was prepared by mixing at room temperature (25° C.) the components shown in Tables 1 to 4. All numerical values ​​for the amounts of components in Tables 1 to 4 are based on the “mass %” of the raw materials.

[0210] [Table 1A]

[0211] [Table 1B]

[0212] [Table 2A]

[0213] [Table 2B]

[0214] [Table 3A]

[0215] [Table 3B]

[0216] [Table 4A]

[0217] [Table 4B]

[0218] [evaluation] (in vitro SPF) Each composition according to Examples 1 to 6 and Comparative Examples 1 to 27 was applied at 1.3 mg / cm 2 was applied onto a PMMA (polymethyl methacrylate) plate at 25° C. After each composition was dried, the UV absorption spectrum of the composition was measured with an SPF analyzer (UV-2000S), and the in vitro SPF value was calculated based on the UVB absorption intensity measured by the SPF analyzer.

[0219] The results are shown in Tables 1 to 4.

[0220] (PPD in vitro) Each composition according to Examples 1 to 6 and Comparative Examples 1 to 27 was applied at 1.3 mg / cm 2 was applied onto a PMMA (polymethyl methacrylate) plate at 25° C. After each composition was dried, the UV absorption spectrum of the composition was measured with an SPF analyzer (UV-2000S), and its in vitro PPD (prolonged immediate darkening) value was calculated by the UVA absorption / UVB absorption ratio based on the UVA absorption and UVB absorption measured by the SPF analyzer.

[0221] The results are shown in Tables 1 to 4.

[0222] (Smoothness during application) Each composition according to Examples 1 to 6 and Comparative Examples 1 to 27 was applied at 2 mg / cm 2 Each sample was applied to the underarms of three experts using their fingers. Panelists rated the smoothness during application on a scale of 1 (not very smooth = squeaky) to 5 (very smooth) and the scores were averaged.

[0223] The results are shown in Tables 1 to 4.

[0224] (Smoothness after rinsing) Each composition according to Examples 1 to 6 and Comparative Examples 1 to 27 was applied at 2 mg / cm 2 The composition was applied to the underarms of three experts using a finger in an amount of 100 ml. The panelists rated the smoothness after rinsing the composition off with tap water on a scale of 2 (not very smooth = squeaky) to 5 (very smooth) and the scores were averaged.

[0225] The results are shown in Tables 1 to 4.

[0226] (stability) After the compositions of Examples 1 to 6 and Comparative Examples 1 to 27 were prepared and stored at 4° C. for one month, each composition was observed under a microscope to confirm crystallization of the organic UV blocking agent.

[0227] Specifically, a small droplet of each of the compositions according to Examples 1 to 6 and Comparative Examples 1 to 27 was placed on a transparent glass plate, covered with a cover glass, and observed under a polarizing microscope (Olympus BX51).

[0228] If no crystals were observed, the result was rated as good.

[0229] If any crystals were observed it was rated as poor.

[0230] The results are shown in Tables 1 to 4.

[0231] (Summary) The compositions according to Examples 1 to 6 (a) can provide sufficient UV protection for both UVA and UVB, and a smooth feel both during application and after rinsing, even though they contain a relatively large amount of TiO2 as an inorganic UV filter.

[0232] Furthermore, the compositions according to Examples 1 to 6 are stable such that no crystals of (b) drometrizole trisiloxane as an organic UV screening agent are found therein.

[0233] The composition according to Comparative Example 1 does not contain drometrizole trisiloxane, therefore the UV protection provided by the composition is not sufficient and its smoothness is not good.

[0234] The composition according to Comparative Example 2 does not contain TiO2, and therefore the UV protection provided by the composition is not sufficient.

[0235] The composition according to Comparative Example 3 contains less than 5 wt. % TiO2, and therefore the UV protection provided by the composition is not sufficient.

[0236] The compositions according to Comparative Examples 4 to 27 do not contain drometrizole trisiloxane and therefore the smoothness during application or after rinsing is not good, or the UV protection (especially against UVA) provided by the compositions is not sufficient.

[0237] (Examples 7 to 11) [Preparation] Each of the compositions according to Examples 7-11 was prepared by mixing at room temperature (25° C.) the components shown in Table 5. All figures for the amounts of components in Table 5 are based on "mass %" of the ingredients.

[0238] [Table 5A]

[0239] [Table 5B]

[0240] [evaluation] (Emulsion stability) The compositions of Examples 7 to 11 were stored at 45° C. for 2 months after preparation, and then each composition was subjected to visual observation.

[0241] Specifically, 40 g of each of the compositions according to Examples 7 to 11 was filled into a transparent glass bottle and stored for 2 months at 45° C. The appearance of the transparent glass bottle was visually confirmed.

[0242] If no change was observed, it was rated as good.

[0243] If there was a slight color change or slight phase separation (eg, oil floating to the top), it was rated as acceptable.

[0244] If any color change or phase separation was observed it was rated as poor.

[0245] The results are shown in Table 5.

[0246] (Summary) The compositions according to Examples 7, 8 and 10 are more stable, whereas the compositions according to Examples 9 and 11, which do not contain isopropyl myristate or potassium cetyl phosphate, are less stable.

[0247] Thus, it is preferred that the composition comprising TiO2 and drometrizole trisiloxane also comprises (c) a fatty substance, such as isopropyl myristate, and / or (d) a phosphate compound, such as potassium cetyl phosphate.
