Description

Title of the invention: STABLE UV PROTECTION COMPOSITION

[0001] The present invention relates to a composition, preferably a cosmetic or dermatological composition, which is stable, comprising at least one UV filter. STATE OF THE ART

[0002] Currently, one of the technical challenges in the cosmetic fields is to provide a stable composition with a high UV protection capacity as well as a soft or non-sticky texture during application.

[0003] Conventional sun care compositions with a high concentration of UV filter(s) for high UV protection performance must have a high concentration of surfactant(s) and ensure good stability of the compositions. However, such a high concentration of surfactant(s) tends to cause a heavy or sticky texture upon application. DISCLOSURE OF THE INVENTION

[0255] (Film homogeneity)

[0256] Each composition in the same amount was applied to a polypropylene sheet (0.2 mm PX-P of Sekisui Kagaku Co. Ltd) by an applicator called "Elcometer 4340" (Elcometer KK) 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) using a UV lamp (UV black ray B-100AP).

[0257] Film homogeneity on the sheet was evaluated by visual observation. A film with good film homogeneity exhibited a strong and homogeneous black color. On the other hand, a film with poor homogeneity exhibited an inhomogeneous translucent blue color. The photo of each film was taken and rated from 1 to 5. (1 means poor 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 placed in a 30 ml beaker and stirred with a small stir bar (0.76 g, 1.5 cm long) at a shear rate of 400 rpm at room temperature for 5 minutes. Then, the composition was observed under microscopy (Olympus BX51-P polarizing microscope) to evaluate the stability of the composition according to 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. Example 11

[0264] The following composition according to Example 11, shown in Table 3, was prepared by mixing the ingredients shown in Table 3 as follows:

[0265] (1) mixing the ingredients of phase A at 60-65°C to form a mixture uniform of phase A;

[0266] (2) adding the ingredients of phase B to the uniform mixture of phase A at 60-65°C, then mix with a homogenizer at 60-65°C to form a uniform mixture of phases A and B;

[0267] (3) adding the ingredients of phase C to the uniform mixture of phases A and B, then mixing with a homogenizer at 60-65°C to form an aqueous phase;

[0268] (4) separately mixing ingredients of phase D at 75-80°C to form a oily phase;

[0269] (5) mixing the aqueous and oily phases at 60-65°C with a homogenizer to obtain a uniform mixture;

[0270] (6) cooling the uniform mixture of phases A, B, C and D to about 40°C; and

[0271] (7) adding the ingredient of phase E to the uniform mixture of phases A, B, C and D at about 40°C, then mix with a homogenizer.

[0272] The composition according to Example 11 was in the form of an O / W emulsion.

[0273] The numerical values ​​of the component amounts shown in Table 3 are all based on the "% by weight" of active ingredients.

[0275] (in vivo SPF)

[0276] The in vivo sun protection factor (SPF) 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 carried out using a UV simulator (UV source: Xenon lamp: Multiport 601-300W sun lamp, v2.5 WG320 filter, Spectrum: 290 to 400 nm).

[0277] The results are shown in Table 3.

[0278] (Texture)

[0279] 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 in an amount of 2 mg / cm2 and 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.

[0280] Good: Soft or non-sticky

[0281] Poor: Not soft or sticky

[0282] The results are shown in Table 3.

[0283] (Summary)

[0284] As shown in Table 1, the compositions according to Examples 1 to 10 are stable and can form a homogeneous film.

[0285] As shown in Table 3, the composition according to Example 11 can provide good UV protection and a good texture of soft or non-sticky feel to the touch during application. The composition according to Example 11 is very similar to the composition according to Example 5. Thus, it is evident that the compositions according to Examples 1 to 10 can also provide good UV protection and a good texture of soft or non-sticky feel to the touch during application.

[0286] Furthermore, Table 2 shows that the absence of any of the ingredients (a) to (d) in the composition according to the present invention adversely affects the stability of the composition and the ability to form a homogeneous film by the composition. It is obvious that the formation of a non-homogeneous film would deteriorate the UV protection.

[0287] For example, Comparative Examples 1-3 demonstrate that 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 film. homogeneous.

[0288] Comparative Example 4 demonstrates that a composition not including a fatty acid polyglyceryl ester cannot form a homogeneous film.

[0289] Comparative Example 5 demonstrates that a composition not including fatty alcohol is not stable and cannot form a homogeneous film.

[0290] Comparative Examples 6 and 7 demonstrate that a composition not including an 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.

[0291] Comparative Example 8 demonstrates that a composition including neither a poly-glyceryl fatty acid ester nor a fatty alcohol is not stable and cannot form a homogeneous film.

[0292] Comparative Example 9 demonstrates that a composition including neither poly-glyceryl fatty acid ester, nor amino acid surfactant, nor fatty alcohol is not stable and cannot form a homogeneous film.

[0293] Comparative Example 10 demonstrates that a composition including neither a poly-glyceryl fatty acid ester nor a fatty alcohol is not stable and cannot form a homogeneous film, even if the composition includes another non-ionic surfactant (sorbitan oleate) other than the polyglyceryl fatty acid ester.
