Description

TECHNICAL FIELD

[0001] The present invention relates to a composition, preferably a cosmetic composition, comprising, in a physiologically acceptable medium, zinc oxide and 2,4-bis-{[(4-(2-ethylhexyloxy)-2-hydroxy)-phenyl]-6-(4-methoxyphenyl)-1,3,5-triazine (INCI name: Bis- Ethylhexyloxyphenol Methoxyphenyl Triazine) in specific amounts, said composition being substantially free of other UV filters. BACKGROUND

[0002] It is known that radiation with a wavelength between 280 nm and 400 nm is capable of tanning the human epidermis, whereas radiation with a wavelength between 280 nm and 320 nm, known as UVB rays, impedes the progress of natural tanning. Exposure can also cause harmful changes in the biomechanical properties of the epidermis, leading to the appearance of wrinkles and causing premature ageing of the skin, i.e. photoageing.

[0003] It is also known that UVA rays, with a wavelength between 320 nm and 400 nm, penetrate the skin more deeply than UVB rays. UVA rays cause immediate and lasting tanning of the skin. Under normal circumstances, daily exposure to UVA rays, even for short periods, can damage the collagen and elastin fibres, leading to microrelief changes in the skin, the appearance of wrinkles and uneven pigmentation (spots, uneven colour).

[0004] A large number of studies have shown that effective protection against UVA and / or UVB rays is required to prevent sunburn and / or photoageing.

[0005] However, many consumers have concerns about the safety of sun protection products, which limits their use. Zinc oxide in particular enjoys a very good reputation and is increasingly used.

[0006] Furthermore, to obtain a high-protection product, it is often necessary to combine a significant number of solar filters and / or high filter contents to achieve a high level of filtering efficacy.

[0007] However, a high UV filter content is not conducive to the easy preparation of compositions with stable and satisfactory textures.

[0008] There is therefore a need to provide consumers with high-efficacy sun protection products comprising a reduced number of solar filters at the lowest possible concentrations, while maintaining good cosmetic acceptability. SUMMARY

[0009] The present invention meets this need.

[0010] In particular, surprisingly, the Applicant found that a composition comprising a specific amount of zinc oxide and 2,4-bis-{[(4-(2-ethylhexyloxy)-2-hydroxy)-phenyl}-6-(4-methoxyphenyl)-1,3,5-triazine (INCI name: Bis- Ethylhexyloxyphenol Methoxyphenyl Triazine, BEMT) and devoid of other sun filters has a synergistic effect in terms of sun protection, thus having an unexpected efficacy.

[0011] The present application thus relates to a composition, preferably a cosmetic composition, comprising, in a physiologically acceptable medium:

[0012] 4.5 to 10 wt% of 2,4-bis-{[(4-(2-ethylhexyloxy)-2-hydroxy)-phenyl}-6-(4- methoxyphenyl)-1,3,5-triazine (INCI name: Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine) relative to the total weight of the composition; and

[0013] 5 to 25 wt% of zinc oxide relative to the total weight of the composition,

[0014] The composition comprises less than 3 wt% of other UV filters relative to the total weight of the composition.

[0015] By "physiologically acceptable medium" is meant a medium compatible with keratin materials. By "keratin materials" is meant, in particular, the skin, the scalp, keratin fibres such as the eyelashes, the eyebrows, the hair on the head and on the body, the nails, the mucous membranes such as the lips, and more particularly the skin and the mucous membranes (body, face, peri-ocular, eyelids, lips, preferably body, face and lips).

[0016] Hereinafter, unless otherwise specified, the limits of a numeric range are included in the range, in particular in the expressions "between... and... " and "from... to...".

[0017] Furthermore, the expressions "at least one" and "at least" used in the present specification are equivalent to the expressions "one or more" and "greater than or equal to", respectively.

[0018] Within the scope of the present application, the filtering efficacy is evaluated using the SPF and UVAPF evaluations.

[0019] For the purposes of the present invention, SPF (Sun Protection Factor) means the sun protection factor, which measures the level of protection against UVB. The SPF value corresponds to the ratio of the shortest period needed to produce a sunburn using a sunscreen composition and the shortest period needed to produce a sunburn without using the product. More specifically, the definition of the term "SPF" is described in the article A new substrate to measure sunscreen protection factors throughout the ultraviolet spectrum, J. Soc. Cosmet. Chem., 40, 127 133 (May / June 1989).

[0020] The evaluation of the SPF (Sun Protection Factor) can be carried out in vitro using The spectrophotometer is carried out in vitro. The plate is the device onto which the sunscreen composition is applied. In this protocol, polymethyl methacrylate (PMMA) plates proved to be ideal. The specific protocol described by way of example is currently being approved by ISO under the name ISO Committee Draft 23675.

[0021] The evaluation of the sun protection factor (SPF) of the composition can also be carried out in vivo according to the ISO-24444:2019 protocol "Cosmetics - Sun protection test methods - In-vivo determination of the sun protection factor (SPF)".

[0022] For the purposes of the present invention, UVAPF means the UVA protection factor. In particular, this factor can be measured in vivo according to the "PPD" (Persistent Pigment Darkening) method, ISO-24442:2022 protocol, and measures the skin color observed 2 to 4 hours after UVA exposure. The evaluation of the UVA protection can also be carried out in vitro using The spectrophotometer is carried out in vitro. The plate is the device onto which the sunscreen composition is applied. In this protocol, polymethyl methacrylate (PMMA) plates proved to be ideal. The ISO24443:2021 protocol describes such an in vitro method.

[0215] The molecular weight is determined by gel permeation chromatography (GPC):

[0216] The samples are prepared by producing a polymer solution in tetrahydrofuran at a concentration of 10 mg / ml.

After visual inspection, the samples appear to be completely dissolved in the solvent.

[0217] The prepared samples are analyzed using a 300 x 7.5 mm porous column (manufactured by Agilent Technologies, Waters 2695 chromatography system, tetrahydrofuran mobile phase and detection by refractive index). After filtration of the sample on a 0.45 μιη nylon filter, the injection is made into the liquid chromatograph. The calibration used for the standards is the Easi Vial narrow polystyrene (PS) standards from Agilent Technologies.

[0218] Calibration is performed using polystyrene standards from 2520000 to 162 daltons.

[0219] The system is equipped with a PSS SECcurity 1260 RI detector. A polystyrene calibration curve is used to determine the average molecular weight. The recording of the chromatogram and the determination of the different molecular weights are performed by the Win GPC Unichrom 81 program.

[0220] The melting point is determined by differential scanning calorimetry (or DSC):

[0231] Examples of formulations

[0232] Example 1 : Measurement of the SPF and UVAPF of comparative compositions and of the compositions of the application

[0233] Comparative compositions C1 and C2 and the composition F1 of the application were prepared according to the following protocol:

[0234] The fatty phase B1 was heated to 80°C. The B2 phase (ZnO) was added, homogenized for 20 minutes with a rotor-stator, then maintained at 65°C; the B phase was obtained.

[0235] The aqueous phase Al was placed in a production tank, heated to 65°C, under stirring. The A2 phase was added, the viscosity of the mixture must increase; the A phase was obtained.

[0236] The B phase was added to the A phase, under stirring, at 65°C, for 10 minutes. Under stirring, the cooling was performed to 35°C / 40°C.

[0240] a.s.: active substance

[0241] Filtering efficacy evaluation protocol

[0242] In vitro: the Sun Protection Factor (SPF) was determined based on the initial absorbance according to the “in vitro” method described by M. Pissavini et al. in International Journal of Cosmetic Science, 40, 263-268 (2018).

[0243] The in vitro UVA Protection Factor (UVAPF) of a sunscreen product against UVA radiation was mathematically calculated by in vitro spectral modeling according to the ISO 24443:2012 (Fr) protocol.

[0244] Each composition was applied at a rate of 1 mg / cm 2 on six rough PMMA panels in a uniform and homogeneous deposit. Each composition was spread using an automatic robot which performed regular and uniform movements on three panels called HD6 (molded granular panels) and on three panels called SB6 (sanded granular panels).

[0245] The plates are weighed before and after spreading. Once the six plates have been spread, they are placed in the Thermo-Master at 25°C for 30 minutes in the dark. Measurements are taken using a Labsphere UV-1000S spectrophotometer. Nine measurements are taken for each plate, then analysed using an Excel spreadsheet to give the SPF and UVAPF values for the composition measured.

[0246] The results are as follows:

[0247] [Table 2]

[0248]

[0249] The combination of ZnO with BEMT produces a synergistic effect, enabling an unexpected efficacy to be obtained which is superior to that predicted by the sum of the efficacy of each filter used alone: the SPF and UVAPF are greater than the expected values for the intrinsic efficacy of each filter on light.

[0250] Example 2: Measurement of the dose effect of comparative compositions and of the compositions of the application

[0251] The comparative compositions A1* to A5* were prepared as described in Example 1.

[0252] [Table 3]

[0253]

[0254]

[0255] The dose effect of these compositions was measured; the results are as follows:

[0256] [Table 4]

[0257] Formulation A1* A2* A3* A4* A5* In vitro SPF 31.9 6.2 9 12.6 15.7 Cut-off wavelength (nm) 371 375 376 376 376 UVAPF 15.8 5.3 7.6 10.4 12.5

[0258] The compositions of the application B1 to B4 were prepared as described in Example 1.

[0259] [Table 5]

[0260]

[0261]

[0262] The dose effect of these compositions was measured; the results are as follows:

[0263] [Table 6]

[0264]

[0265] The results show that for the various zinc oxide contents tested, the synergistic effect is confirmed.

[0266] Furthermore, it is noted that the in vitro SPF of the composition B2 according to the application (without butyl octyl salicylate) is 71.5, higher than the in vitro SPF of the composition Fl according to the application (containing 3% of butyl octyl salicylate), which is 69.8.
