Description

Title of the invention: EMULSION COMPOSITIONS CONTAINING BIS-ETHYLHEXYLOXYPHENOL ME-THOXYPHENYL TRIAZINE AND A SEMI-CRYSTALLINE POLYMER FIELD OF INVENTION

[0001] This disclosure relates to compositions comprising 2,4-bis-{[4-(2-ethylhexyloxy)-2-hydroxy]-phenyl]-6-(4-methoxyphenyl)-1,3,5-triazine (INCI name: bis-ethylhexyloxyphenol methoxyphenyl triazine) and at least one semi-crystalline polymer, as well as processes for manufacturing and using such compositions. DISCUSSION OF THE CONTEXT

[0002] Radiation with wavelengths between 290 nm and 400 nm allows the human epidermis to tan, while radiation with wavelengths between 290 and 320 nm, known as UVB rays, hinders the development of a natural tan. Exposure is also likely to cause a detrimental alteration of the biomechanical properties of the epidermis, resulting in the appearance of wrinkles and leading to premature skin aging (i.e., photoaging).

[0003] UVA rays with wavelengths between 320 and 400 nm penetrate the skin more deeply than UVB rays. UVA rays cause immediate and persistent tanning of the skin. Daily exposure to UVA rays, even for a short period, under normal conditions can damage collagen and elastin fibers, resulting in changes to the skin's microrelief, the appearance of wrinkles, and uneven pigmentation (spots, uneven skin tone).

[0004] Numerous studies show the need for effective protection against UVA and UVB to prevent sunburn, photoaging, and the like.

[0005] In order to obtain a product with high protection, it is generally necessary to combine a large number of sunscreens and / or a large quantity of UV filters to obtain high levels of filtration efficiency.

[0006] However, high levels of UV filters do not lend themselves to the easy preparation of compositions, particularly emulsions, with a stable and pleasant texture.

[0007] There remains a need in the art of consumer care compositions improved ones that have organic UV filters and pleasant application properties (e.g., non-greasy feel) and UV protection properties.

[0008] Therefore, one aspect of the present disclosure is a composition that possesses organic UV filters and has pleasant application properties (e.g., non-greasy feel) and UV protection properties. Summary of the invention

[0009] This disclosure relates to emulsion compositions (emulsions) comprising bis-ethylhexyloxyphenol methoxyphenyl triazine (BEMT or bemo-trizinol) and at least one semi-crystalline polymer. Preferably, the emulsions are in the form of an oil-in-water emulsion. Preferably, the compositions further comprise at least one surfactant selected from the group consisting of alkyl polyglucosides, fatty acid polyol esters, anionic carboxylic surfactants or carboxylates, and mixtures thereof. Preferably, the compositions further comprise at least one salt-chelating agent.

[0023] “Exempt” or “substantially exempt” or “devoid of”, as used herein This means that, although it is preferable that no quantity of the specific component be present in the composition, it is possible for very small quantities of it to be present in the compositions of the disclosure, provided that these quantities do not materially affect at least one, preferably most, of the advantageous properties of the compositions of the disclosure. Thus, for example, "dye-free" means that an effective amount (i.e., greater than the amounts to the trace state) of colorant is omitted from the composition (i.e., about 0% by weight), "substantially free of colorant" means that one or more colorants is / are present in quantities not exceeding 0.1% by weight, and "free of colorant" means that one or more colorants is / are present in quantities not exceeding 0.25% by weight, relative to the total weight of the composition.The same nomenclature applies to all other ingredients identified throughout the application and in this paragraph, such as, for example, specific UV filters and / or surfactants (the disclosure compositions that are "free of oxybenzone and / or octinoxate," "substantially free of oxybenzone and / or octinoxate," and "devoid of oxybenzone and / or octinoxate," as well as "surfactant-free," "substantially free of surfactants," and "devoid of surfactants" have meanings consistent with the discussion in this paragraph), even if they are not specifically mentioned for each ingredient identified in the application. The examples of the use of such language as those in this paragraph are intended to be provided by way of example, not limitation.

[0024] “UV Filters” as used herein means approved sunscreen active agents by a government regulatory agency such as the Food and Drug Administration (FDA) in the United States or the European Commission in Europe and includes avobenzone, octocrylene, benzophenones, benzotriazoles and mero-cyanines, as well as mineral UV filters such as zinc oxide (ZnO) and titanium dioxide (TiO2).

Preferably, the pH of the composition is 5 or higher, preferably 6 or higher, preferably 6.5 or higher, and preferably 7 or higher.

[0027] “UV protection efficiency” or “filtering efficiency” in the In the context of this disclosure, is evaluated from one or more of FPS, FPUVA, critical wavelength and UVA-l / UV ratio.

[0028] The "SPF" (Sun Protection Factor) measures the level of protection against erythema provided by a composition. The SPF value corresponds to the ratio between the minimum erythemal dose (MED) measured on skin covered with the composition and the MED measured on bare skin. The term "SPF" is known in the sunscreen industry. solar and is defined, for example, in A new substrate to measure sunscreen protection factors throughout the ultraviolet spectrum, J. Soc. Cosmet. Chem., 40, 127-133 (May / June 1989).

[0029] The evaluation of the SPF (Sun Protection Factor) can be carried out, for example, in vitro with a spectrophotometer from Labsphere (North Sutton, NH, USA). In such an evaluation, the plate is the material onto which the composition under test is applied. For such an evaluation, polymethyl methacrylate (PMMA) plates can be used. An example of an acceptable protocol is currently undergoing ISO accreditation under the name ISO Committee Draft 23675.

[0030] The evaluation of the sun protection factor (SPF) can also be performed in vivo in accordance with ISO 24444:2019 "Cosmetics — Sun protection test methods — In vivo determination of the sun protection factor (SPF)." In addition, it can be determined in accordance with FDA protocols, as described in the document "Labeling and Effectiveness Testing; Sunscreen Drug Products for Over-the-Counter Human Use" published in the US Federal Register on 07 / 05 / 2011 (https: / / www.federalregister.gov / d / 2011-14766); 21 CFR Part 352 Subpart D § 352.72, updated and revised by the 2011 publication in the Federal Register.

[0031] “UVA protection factor” refers to an index characterizing the UVA protection provided by a composition. For example, the UVA protection factor (UPPF) can be measured in vivo according to the "PPD" (Persistent Pigment Darkening) method of the ISO-24442:2022 protocol, measuring skin color observed 2 to 4 hours after UVA exposure. Additionally, it can be determined according to FDA protocols, as described in 21 CFR Part 352 Subpart D § 352.72, as mentioned above in relation to SPF.

[0032] UVA protection can also be assessed in vitro using the Labsphere® spectrophotometer under conditions such as those mentioned above in relation to the SPF. ISO 24443:2021 describes such an in vitro procedure.

[0033] FDA broad-spectrum test procedures, particularly "critical wavelength" test procedures, are also available in 21 CFR Part 352 Subpart D § 352.72. In addition, broad-spectrum test procedures include the determination of the UVA1 / UV ratio as described in "Sunscreen Drug Products for Over-the-Counter Human Use" published in the Federal Register https: / / www.federalregister.gov / documents / 2019 / 02 / 26 / 2019-03Q19 / sunscreen-drug-products-for-over-the-counter-human-use. "In the test described in the monograph, known as the Boots adaptation of the Diffey / Robson test method, a ratio is generated between the protection offered by the sunscreen product against UVA1 (340 to 400 nm) and the protection against total UV radiation (UVB and UVA at 290 to 400 nm) calculated from the absorbance curve. This UVA1 / UV ratio would represent the product's score in the in vitro test.

[0034] According to this disclosure, the compositions in this disclosure preferably have one or more of the following properties:

[0035] The compositions have a critical wavelength, as determined by FDA critical wavelength procedures, of at least 370 nm;

[0036] The compositions have an FPS value of at least 15, preferably at least 30, preferably at least 50 and preferably at least 70;

[0037] The compositions have an FPUVA / FPS ratio of at least 1 / 3, and preferably of at least 2 / 5; and / or

[0038] The compositions have a UVA1 / UV ratio of 0.7 or more, preferably 0.75 or more, and preferably 0.8 or more.

[0039] “The makeup effect”, as used herein, refers to the visual impact of a com The position when applied to a keratinous material such as skin. The makeup result can refer to the apparent color of the product after application to a keratinous material or an optical effect such as shine, blurring of fine lines and imperfections, or a concealing effect on pores or blemishes after application of the product to the keratinous material.

[0040] "Longevity," as used herein, refers to compositions where the color or other apparent properties remain the same or substantially the same as at the time of application, as seen with the naked eye, after a prolonged period or after a particular stress event such as immersion in water or rubbing. "Longevity" can be evaluated by assessing the longevity properties by any method known in the art for evaluating such properties. For example, longevity can be assessed by a test involving the application of a composition to a keratinous material such as skin and evaluating the color of the composition after a prolonged period. For example, the color of a composition can be evaluated immediately after application to a keratinous material such as skin, and these characteristics can then be re-evaluated and compared after a certain time.Furthermore, these characteristics can be evaluated against other compositions, such as commercially available ones. "Longevity" can also be assessed using in vitro processes on non-keratinous substrates such as polymethyl methacrylate (PMMA), in which properties such as color, transparency, or in vitro FPS can be evaluated before and after a period or stress factor such as immersion in water, incubation at high temperatures, or the application of an abrasive technique.

[0041] “Natural” as in the expression “natural compound” means any compound derived directly from a natural substance such as a plant without having undergone any modification chemical modification.

[0042] “Compound of natural origin” refers to any compound derived from a compound natural which has undergone one or more chemical modifications, for example by organic synthesis reaction, without the properties of the natural compound having been modified.

[0043] “Synthetic compound” refers to any compound that is not a compound natural nor a compound of natural origin.

[0044] “Room temperature” means approximately 20 to 25 °C.

[0045] “Atmospheric pressure” means approximately 760 mmHg, i.e. approximately 105 pascals.

[0046] “UV filter” and “sunscreen agent” are used interchangeably in the present request.

[0047] “UV efficiency”, “UV protection” and “Efficiency against UV” are used of interchangeable in this request.
