The present disclosure relates to compositions comprising 2,4-bis-{[4-(2-ethyl hexyloxy)-2-hydroxy]-phenyl}-6-(4-methoxyphenyl)-1,3,5-triazine (INCI name: bis-ethylhexyloxyphenol methoxyphenyl triazine), at least one semi-crystalline polymer, and at least one scleroglucan gum, as well as to methods of making and using such compositions.
Radiation of wavelengths between 290 nm and 400 nm allows tanning of the human epidermis, while radiation of wavelengths between 290 and 320 nm, called UVB rays, hinders the development of a natural tan. Exposure is also likely to lead to a detrimental change in the biomechanical properties of the epidermis, resulting in the appearance of wrinkles leading to premature aging of the skin (i.e. photoaging).
UVA rays with wavelengths between 320 and 400 nm penetrate deeper into the skin than UVB rays. UVA rays cause immediate and persistent browning of the skin. Daily exposure to UVA rays, even for a short time, under normal conditions can damage collagen fibers and elastin, resulting in a change in the microrelief of the skin, the appearance of wrinkles and uneven pigmentation (spots, lack of uniformity of complexion).
Many studies show the need for effective protection against UVA and UVB to prevent sunburn, photoaging, and the like.
In order to obtain a high protection product, it is generally necessary to combine a large number of sunscreens and/or a high amount of UV filters to achieve high levels of filtering efficiency.
However, high levels of UV filters do not lend themselves to an easy elaboration of compositions with a stabilized and pleasant texture.
There remains a need in the art for improved consumer care compositions which possess organic UV filters and have pleasant application properties (e.g., non-greasy feeling) and UV protection properties.
Accordingly, one aspect of the present disclosure is a composition which possesses organic UV filters and has pleasant application properties (e.g., non-greasy feeling) and UV protection properties.
The present disclosure relates to compositions comprising bis-ethylhexyloxyphenol methoxyphenyl triazine (BEMT or bemotrizinol), at least one semi-crystalline polymer, and at least one scleroglucan gum. Preferably, the compositions are in the form of an emulsion, preferably an oil-in-water emulsion. Preferably, the compositions further comprise at least one surfactant selected from the group consisting of alkylpolyglucosides, polyol fatty acid esters, anionic carboxylic surfactants or carboxylates, and mixtures thereof. Preferably, the pH of the composition is 6 or higher.
The present disclosure also relates to methods of treating, caring for, protecting, enhancing the appearance of, and/or making up a keratinous material comprising applying compositions of the present disclosure to a keratinous material in an amount sufficient to treat, care for, enhance the appearance of, and/or make up the keratinous material.
The present disclosure also relates to methods of making compositions comprising combining bis-ethylhexyloxyphenol methoxyphenyl triazine, at least one semi-crystalline polymer, and at least one scleroglucan gum during formation of the compositions. Preferably, the compositions are produced in the form of an emulsion, preferably an oil-in-water emulsion. Preferably, the methods further comprise adding at least one surfactant selected from the group consisting of alkylpolyglucosides, polyol fatty acid esters, anionic carboxylic surfactants or carboxylates, and mixtures thereof, during formation of the compositions, preferably emulsion compositions. Preferably, the pH of the composition is 6 or higher.
It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only, and are not restrictive of the disclosure.
In the following description and the claims appended hereto, it is to be understood that the terms used have their ordinary and accustomed meanings in the art, unless otherwise specified.
“About” as used herein means within 10% of the indicated number (e.g., “about 10%” means 9%-11% and “about 2%” means 1.8%-2.2%).
“A” or “an” as used herein means “at least one.”
“At least one” means one or more and thus includes individual components as well as mixtures/combinations.
As used herein, all ranges provided are meant to include every specific point and range within, and combination of subranges between, the given ranges. Thus, a range from 1-5 includes specifically the integers within the range 1, 2, 3, 4 and 5, as well as subranges such as and 2-5, 3-5, 2-3, 2-4, 1-4, etc., as well as all fractional numbers within the range such as 1.2, 2.3, 3.4, etc., and subranges including such fractional numbers such as 1.5-3.8, 2-4.3, 4.2-4.9, etc.
“Film former”, “film-forming polymer” or “film-forming agent” as used herein means a polymer or resin which is capable of leaving a film on the substrate to which it is applied, for example, after a solvent accompanying the film former has evaporated, absorbed into and/or dissipated on the substrate.
“Substituted” as used herein, means comprising at least one substituent. Non-limiting examples of substituents include atoms, such as hydrogen atoms or chlorine atoms, as well as functional groups, such as hydroxyl groups, ether groups, alkoxy groups, acyloxyalky groups, oxyalkylene groups, polyoxyalkylene groups, carboxylic acid groups, amine groups, acylamino groups, amide groups, halogen containing groups, ester groups, thiol groups, sulphonate groups, thiosulphate groups, siloxane groups, and polysiloxane groups. The substituent(s) may be further substituted.
“Volatile”, as used herein, means having a flash point of less than about 115° C.
“Non-volatile”, as used herein, means having a flash point of greater than about 115° C.
“Polymer” as used herein means a compound which is made up of at least two monomers.
“Free” or “substantially free” or “devoid of” as it is used herein means that while it is preferred that no amount of the specific component be present in the composition, it is possible to have very small amounts of it in the compositions of the disclosure provided that these amounts do not materially affect at least one, preferably most, of the advantageous properties of the compositions of the disclosure. Thus, for example, “free of colorant” means that an effective amount (that is, more than trace amounts) of colorant(s) is/are omitted from the composition (that is, about 0% by weight), “substantially free of colorants” means that colorant(s) is/are present in amounts not greater than 0.1% by weight, and “devoid of colorant” means that colorant(s) is/are present in amounts not greater than 0.25% by weight, based on the total weight of the composition. The same nomenclature applies for all other ingredients identified throughout the application and in this paragraph such as, for example, specific UV filters and/or surfactants (compositions of the disclosure which are “free of oxybenzone and/or octinoxate,” “substantially free of oxybenzone and/or octinoxate,” and “devoid of oxybenzone and/or octinoxate,” as well as “free of surfactants,” “substantially free of surfactants,” and “devoid of surfactants,” have meanings consistent with the discussion within this paragraph), even if not specifically discussed for each identified ingredient in the application. Discussed examples of the use of such language such as those in this paragraph are intended to be exemplary, not limiting.
“UV filters” as it is used herein means sunscreen active agents approved by a governmental regulatory agency such as the Food and Drug Administration (FDA) in the U.S. or the EU Commission in Europe and includes organic UV filters such as avobenzone, octocrylene, benzophenones, benzotriazoles and merocyanines, as well as mineral UV filters such as zinc oxide (ZnO) and titanium dioxide (TiO2).
“Anhydrous” as it is used herein means that compositions of the disclosure contain less than 3% water, meaning that the compositions can also contain less than 2% water, and less than 1% water, as well as being “free of water,” “substantially free of water,” and “devoid of water” as defined above.
“Keratinous materials” means nails (finger and/or toe nails), skin such as body, face, and eye area, scalp, keratin fibers such as eyelashes, eyebrows, and hair, and mucous membranes such as lips.
“Physiologically acceptable” means compatible with keratinous materials and having a pleasant color, odor and feel, and which does not cause any unacceptable discomfort (stinging or tautness) liable to discourage a consumer from using the composition. Preferably, the pH of the composition is 6 or higher, preferably 6.5 or higher, and preferably 7 or higher.
“UV protection efficiency” or “filtering efficiency” in the context of the present disclosure, is evaluated from one or more of SPF, UVAPF, Critical Wavelength, and UVA-I/UV ratio.
“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 dosage (MED) measured wearing the composition and the MED measured with bare skin. “SPF” is a known term in the sunscreen art 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).
The evaluation of the SPF (Sun Protection Factor) can be performed, for example, in vitro with spectrophotometer by Labsphere (North Sutton, NH, USA). In such an evaluation, the plate is the material on which the tested composition is applied. For such an evaluation, polymethylmethacrylate (PMMA) plates can be used. An example of an acceptable protocol is in the process of ISO accreditation under the name ISO Committee Draft 23675.
The evaluation of the Sun Protection Factor (SPF) can also be performed in-vivo according to the ISO 24444:2019 protocol “Cosmetics-Sun protection test methods-In-vivo determination of the sun protection factor (SPF).” Also, it can be determined according to 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 Jul. 5, 2011 (https://www.federalregister.gov/d/2011-14766); 21 C.F.R. Part 352 Subpart D § 352.72, updated and revised by the 2011 publication in the Federal Register.
“UVAPF” (UVA protection factor) relates to an index characterizing the protection against UVA provided by a composition. For example, the UVAPF index can be measured in vivo according to the “PPD” (Persistent Pigment Darkening) method in the ISO-24442:2022 protocol, measuring observed skin color 2 to 4 hours after UVA exposure. Also, it can be determined according to FDA protocols, again as described in 21 C.F.R. Part 352 Subpart D § 352.72 as discussed above in connection with SPF.
The evaluation of UVA protection can also be measured in vitro with the Labsphere® spectrophotometer under conditions such as those discussed above in connection with SPF. ISO 24443:2021 protocol describes such an in vitro method.
FDA broad spectrum testing procedures, in particular “critical wavelength” testing procedures, can also be found at 21 C.F.R. Part 352 Subpart D § 352.72. Also, broad spectrum testing procedures include determining 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/2019/02/26/2019-03019/sunscreen-drug-products-for-over-the-counter-human-use.” In the assay outlined in the monograph, known as the Boots adaptation of the Diffey/Robson test method, a ratio is generated of the protection afforded by the sunscreen product from UVA1 (340-400 nm) compared to the protection from total UV radiation (UVB and UVA at 290-400 nm) calculated from the absorbance curve. This ratio UVA1/UV would represent the score for the product in the in vitro test.
According to the present disclosure, compositions of the present disclosure preferably have one or more of the following properties:
“Makeup Result” as used herein relates to the visual impact of a composition when applied to a keratinous material such as the skin. The makeup result may relate to the apparent color of the product after application on a keratinous material or an optical effect such as shine, blurring of fine lines and imperfections, or hiding effect on pores or blemishes after the product is applied to the keratinous material.
“Long wear” as used herein refers to compositions where color or other apparent properties remains the same or substantially the same as at the time of application, as viewed by the naked eye, after an extended period of time or after a particular stress event such as water immersion or rubbing. “Long wear” may be evaluated by evaluating long wear properties by any method known in the art for evaluating such properties. For example, long wear may be evaluated by a test involving the application of a composition to keratinous material such as skin and evaluating the color of the composition after an extended period of time. For example, the color of a composition may be evaluated immediately following application to keratinous material such as skin and these characteristics may then be re-evaluated and compared after a certain amount of time. Further, these characteristics may be evaluated with respect to other compositions, such as commercially available compositions. “Long wear” may also be evaluated using vitro methods on non-keratinous substrates such as polymethylmethacrylate (PMMA), wherein properties such as color, transparency, or vitro SPF may be evaluated before and after a period of time or stressor such as water immersion, incubation at elevated temperatures, or an abrasive technique is applied.
“Natural” as in the phrase “natural compound” refers to any compound derived directly from a natural substance such as a plant without having undergone any chemical modification.
“Compound of natural origin” refers to any compound derived from a natural compound which has undergone one or more chemical modifications, for example by organic synthesis reaction, without the properties of the natural compound having been modified.
“Synthetic compound” refers to any compound which is not a natural compound or a compound of natural origin.
“Room temperature” means about 20-25° C.
“Atmospheric pressure” means about 760 mmHg, i.e. about 105 pascals.
“UV filter” and “sunscreen agent” are used interchangeably in this application.
“UV efficacy” and “UV efficiency” are used interchangeably in this application.
The compositions and methods of the present disclosure can comprise, consist of, or consist essentially of the essential elements and limitations of the disclosure described herein, as well as any additional or optional ingredients, components, or limitations described herein or otherwise useful. For example, the UV (ultraviolet) absorbing system of the compositions of the disclosure can “consist essentially of” bis-ethylhexyloxyphenol methoxyphenyl triazine.”
For purposes of the present disclosure, the “basic and novel property” associated with compositions, components and methods which “consist essentially of” identified ingredients or actions is “UVA protection indicated by UVAPF/SPF and UVA1/UV ratios.”
Compositions of the present disclosure may be in any form suitable for use as a personal care composition, such as that of a stick, a paste, a cream. These compositions can be used for any personal care purpose in cosmetic and/or dermatological products such as, for example, a sunscreen, a foundation, lip balms, lipsticks, concealers, mascaras, leave-in hair products, etc.
Referred to herein are trade names for materials including, but not limited to, materials such as polymers and optional components. Materials are not intended to be limited by materials described and referenced by a certain trade name herein. Equivalent materials (e.g., those obtained from a different source under a different name or catalog (reference) number) to those referenced by trade name may be substituted and utilized in the methods described and claimed herein.
All percentages and ratios are calculated by weight unless otherwise indicated. All percentages are calculated based on the total weight of a composition unless otherwise indicated. All component or composition levels are in reference to the active level of that component or composition, and are exclusive of impurities, for example, residual solvents or by-products, which may be present in commercially available sources.
All U.S. patents or patent applications disclosed herein are expressly incorporated by reference in their entirety.

When the crystallizable part is a sequence of the polymeric skeleton, this crystallizable sequence is of a chemical nature different from that of the amorphous sequences; the semi-crystalline polymer is in this case preferably a block polymer, for example of the diblock, triblock or multiblock type, comprising at least one crystallizable sequence and at least one amorphous sequence. By “sequence,” it is meant that at least 5 identical repetition patterns exist. The crystallizable sequence(s) are of a chemical nature different from the amorphous sequence(s).

The term “lipophilic compound” refers to a compound having an acid number and a hydroxyl number of less than 150 mg KOH/g.
Melting point corresponds to the temperature of the most endothermic peak observed on thermal analysis (DSC) as described in standard ISO 11357-3; 1999. The melting point of the wax may be measured using a differential scanning calorimeter (DSC), for example the calorimeter sold under the name MDSC 2920 by TA Instruments or the calorimeter sold under the name DSC Q100 by TA Instruments with the TA Universal Analysis software.
A measuring protocol is as follows:
A sample of 5 mg of wax placed in a crucible is subjected to a first temperature ramp passing from −20° C. to 100° C., at a heating rate of 10° C./minute, it is then cooled from 100° C. to −20° C. at a cooling rate of 10° C./minute and is finally subjected to a second temperature ramp passing from −20° C. to 100° C. at a heating rate of 5° C./minute. During the second temperature ramp, the variation in the difference in power absorbed by the empty crucible and by the crucible containing the sample of wax is measured as a function of the temperature. The melting point of the compound is the temperature value corresponding to the top of the peak of the curve representing the variation in the difference in power absorbed as a function of the temperature.
