[0006] BACKGROUND ART

[0007] Currently, one technical challenge in cosmetic fields is to provide a stable composition with high UV protection capability as well as smooth or non-sticky texture upon application.

[0008] Conventional suncare compositions with a high concentration of UV filter(s) for high UV protection performance need to have a high concentration of surfactant(s) as well to secure good stability of the compositions. However, such a high concentration of surfactant(s) tends to cause heavy or sticky texture upon application.

[0034] BEST MODE FOR CARRYING OUT THE INVENTION

[0035] After diligent research, the inventors have discovered that it is possible to provide a stable composition which can provide a homogeneous film that provides good UV protection.

[0041] The composition according to the present invention is UV shielding or is capable of shielding UV rays, because it includes (c) at least one UV filter.

[0042] The composition according to the present invention can form a homogeneous or uniform film including the (c) UV filters) that can provide a homogeneous or uniform distribution of the (c) UV filter(s), which can provide good UV protection.

[0043] The composition according to the present invention is stable. The term “stable” here means that the aspect of a composition does not change, for example, as a result of aggregation or phase separation. It is preferable that the composition according to the present invention is stable over a long time of period.

[0044] Also, the composition according to the present invention can provide good texture such as a smooth or non-sticky feeling to touch during application. In other words, the composition according to the present invention is not sticky upon application onto a keratin substance such as skin. The term “sticky” here means a property which provides a tacky feeling to the skin.

[0045] In summary, the composition according to the present invention is stable and can form a homogeneous or uniform film which can provide good UV protection. In addition, the composition according to the present invention can provide good texture such as a smooth or non-sticky feeling to touch during application.

[0059] The amino acid gemini surfactant is anionic and comprises a plurality of hydrophobic moieties and a plurality of hydrophilic moieties.

[0060] The amino acid gemini surfactant may be selected from compounds with two or more fatty amide groups (hereafter, it may be referred to as “amide compound”). The amide compound may be represented by the following formula (A): wherein

[0194] Preferably, the silicone oil is chosen from liquid polydialkylsiloxanes, especially liquid polydimethylsiloxanes (PDMS) and liquid polyorganosiloxanes comprising at least one aryl group.

[0195] These silicone oils may also be organomodified. The organomodified silicones that can be used in accordance with the present invention are silicone oils as defined above and comprise in their structure one or more organofunctional groups attached via a hydrocarbon-based group.

[0196] Organopolysiloxanes are defined in greater detail in Walter Noll’s Chemistry and Technology of Silicones (1968), Academic Press. They may be volatile or non-volatile.

[0197] When they are volatile, the silicones are more particularly chosen from those having a boiling point of between 60°C and 260°C, and even more particularly from:

An example is decamethyltetrasiloxane sold in particular under the name SH 200 by the company Toray Silicone. Silicones belonging to this category are also described in the article published in Cosmetics and Toiletries, Vol. 91, Jan. 76, pp. 27-32, Todd & Byers, Volatile Silicone Fluids for Cosmetics.

[0254] [Evaluations]

[0255] (Film Homogeneity)

[0256] Each composition in the same amount was applied on a polypropylene sheet (0.2 mm PX-P from Sekisui Kagaku Co. Ltd) by an applicator called "Elecometer 4340" (Elecometer K.K.) with a weight of 1 kg, and dried to form a film on the sheet. Then, the applied sheet was exposed to UV (wavelength 365 nm) by using a UV lamp (UV black ray B-100AP).

[0257] The homogeneity of the film on the sheet was evaluated with visual observation. A film with good film homogeneity showed homogeneous intensive black color. On the other hand, a film with poor homogeneity showed non-homogeneous translucent blue color. The picture of each film was taken and scored from 1 to 5. (1 means low film homogeneity while 5 means high film homogeneity).

[0258] The results of the above evaluation as an average score are shown in Table 1.

[0259] (Stability)

[0260] 3 g of each composition was put in a 30 ml beaker, and stirred with a small stirrer bar (0.76 g, 1.5 cm length) at a shear speed of 400 rpm at room temperature for 5 minutes. Then, the composition was observed under microscopy (Olympus Polarizing Microscope BX51-P) to evaluate the stability of the composition in accordance with the following criteria.

[0261] Good: No phase separation or no aggregation

[0262] Poor: Phase separation or aggregation

[0263] The results of the above evaluation are shown in Table 1.

[0264] Example 11

[0265] The following composition according to Example 11, shown in Table 3, was prepared by mixing the ingredients shown in Table 3 as follows:

[0266] (1) mixing the ingredients of Phase A at 60-65°C to form a uniform mixture of Phase A;

[0267] (2) adding the ingredients of Phase B to the uniform mixture of Phase A at 60-65 °C followed by mixing with a homogenizer at 60-65°C to form a uniform mixture of Phases A and B;

[0268] (3) adding the ingredients of Phase C to the uniform mixture of Phases A and B followed by mixing by a homogenizer at 60-65°C to form an aqueous phase;

[0269] (4) separately mixing the ingredients of Phase D at 75-80°C to form an oil phase;

[0270] (5) mixing the aqueous and oil phases at 60-65 °C with a homogenizer to obtain a uniform mixture;

[0271] (6) cooling the uniform mixture of Phases A, B, C and D to about 40°C; and

[0272] (7) adding the ingredient of Phase E to the uniform mixture of Phases A, B, C and D at about 40°C followed by mixing with a homogenizer.

[0273] The composition according to Example 11 was in the form of an O / W emulsion.

[0274] The numerical values for the amounts of the components shown in Table 3 are all based on “% by weight” as active ingredients. Table 3 [Evaluations]

[0275] (SPF in vivo)

[0276] The Sun Protection Factor (SPF) in vivo of the composition according to Example 11 was determined in accordance with ISO / EN 24444 (2019) Cosmetics-Sun protection test methods- In vivo determination of the sun protection factor (SPF). This test was performed using a UV simulator (UV source: Xenon lamp: Solar Light type Multiport 601-300W, v2.5 Filter WG320, Spectrum: 290 to 400 nm). The results are shown in Table 3.

[0277] (Texture) The texture during application of the composition according to Example 11 to the skin was evaluated by applying the composition to a forearm of a panelist at an amount of 2 mg / cm2and then assessing the friction force felt between the fingers and the surface of the forearm by the panelist. The texture was evaluated in accordance with the following criteria.

[0278] Good: Smooth or not sticky

[0279] Poor: Not smooth or sticky

[0280] The results are shown in Table 3.

[0281] (Summary)

[0282] As shown in Table 1, the compositions according to Examples 1-10 are stable and can form a homogeneous film.

[0283] As shown in Table 3, the composition according to Example 11 can provide good UV protection and good texture of smooth or non-sticky feeling to touch during application. The composition according to Example 11 is very similar to the composition according to Example 5. Thus, it is clear that the compositions according to Examples 1-10 can also provide good UV protection and good texture of smooth or non-sticky feeling to touch during application.

[0284] On the other hand, Table 2 shows that absence of any of the ingredients (a) to (d) in the composition according to the present invention negatively affects the stability of the composition and the ability of forming a homogeneous film by the composition. It is clear that the formation of a non-homogeneous film would deteriorate UV protection.

[0285] For example, Comparative Examples 1-3 demonstrate that the compositions including a polyglyceryl fatty acid ester with a fatty acid moiety including more than 16 carbon atoms are not stable and cannot form a homogeneous film.

[0286] Comparative Example 4 demonstrates that a composition including no polyglyceryl fatty acid ester cannot form a homogeneous film.

[0287] Comparative Example 5 demonstrates that a composition including no fatty alcohol is not stable and cannot form a homogeneous film.

[0288] Comparative Examples 6 and 7 demonstrate that a composition including no amino acid surfactant is not stable and cannot form a homogeneous film, even if the composition includes another anionic surfactant (sodium lauryl sulfate or stearic acid with potassium hydroxide) other than the amino acid surfactant.

[0289] Comparative Example 8 demonstrates that a composition including neither polyglyceryl fatty acid ester nor fatty alcohol is not stable and cannot form a homogeneous film.

[0290] Comparative Example 9 demonstrates that a composition including neither polyglyceryl fatty acid ester, amino acid surfactant, nor fatty alcohol is not stable and cannot form a homogeneous film. Comparative Example 10 demonstrates that a composition including neither polyglyceryl fatty acid ester nor fatty alcohol is not stable and cannot form a homogeneous film, even if the composition includes another nonionic surfactant (sorbitan oleate) other than the polyglyceryl fatty acid ester.
