Description

Title of the invention: Compositions containing a UV-absorbing system comprising a UV-attenuating physical material and an emollient system FIELD OF INVENTION

[0001] This disclosure relates to compositions comprising a UV-absorbing system including at least one physical ultraviolet (UV) attenuating material and an emollient system including at least three emollients, as well as methods for manufacturing and using such compositions. BACKGROUND DISCUSSION

[0002] Exposure to radiation with wavelengths between 290 nm and 400 nm, known as UV radiation or simply "UVR," is implicated in a number of skin diseases and conditions. Exposure to radiation with wavelengths between 290 and 320 nm, also known as UVB radiation, can lead to numerous adverse changes in the biomechanical properties, appearance, and health of the epidermis, resulting in erythema (sunburn), immediate darkening of the skin, the appearance of wrinkles leading to premature skin aging (i.e., photoaging), and various other skin health problems that may include melanoma or other photocancers of the skin.

[0003] UVA rays with wavelengths between 320 and 400 nm penetrate the skin more deeply than UVB rays. Exposure to UVA rays can cause immediate and persistent tanning of the skin, as well as other changes in skin texture or appearance. Daily exposure to UVA rays, even for a short period under normal conditions, can damage collagen and elastin fibers, resulting in changes in 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 other skin conditions or diseases related to UVR exposure.

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

[0006] However, high levels of UV filters do not lend themselves to the easy formulation of stable compositions with a pleasant texture. It is possible to obtain high UV protection using one or more organic UV filters; however, organic UV filters are often very greasy and unpleasant when applied to the skin, particularly when used at high levels in a sunscreen formulation required for high UV protection efficacy.

[0007] Mineral UV filters such as titanium dioxide or zinc oxide are alternative UV filter choices to organic UV filters that can provide more pleasant textures; however, when one or more mineral UV filters are used, the resulting sunscreen formulation is far too whitening (i.e., it leaves "white streaks") when applied to the skin. When mineral UV filters are used at lower levels, it may be possible to produce sunscreen formulations with little or no whitening when applied to the skin; however, such formulations, containing low levels of mineral UV filters, are unable to produce the desired high levels of UV protection.

[0008] Finally, it can be difficult to combine an organic UV filter and a mineral UV filter in a single composition, especially in order to obtain a non-greasy, pleasant, non-whitening and high UV protection sunscreen formulation, particularly taking into account the need to balance the effectiveness of UVA and UVB protection.

[0009] There remains a need in the art of improved sunscreen compositions which have high UV protection and balanced UVA and UVB protection, which are not greasy, which are pleasant to apply and which do not leave white marks when applied to the skin.

[0010] Therefore, one aspect of the present disclosure is a composition that is not greasy, that does not whiten when applied to the skin, and that has high UV protection. Summary of the invention

Preferably, the compositions are non-greasy and / or non-bleaching (i.e., the compositions do not leave white residue) upon application.

[0012] This disclosure also relates to processes for the treatment, care, protection, enhancement of appearance and / or makeup of keratinous material, including the application of compositions of this disclosure to keratinous material in sufficient quantity to treat the keratinous material, care for it, enhance its appearance and / or make it up.

[0013] This disclosure also relates to processes for manufacturing non-greasy and / or non-bleaching compositions comprising at least one ultraviolet (UV) attenuating physical material by combining at least one ultraviolet (UV) attenuating physical material, at least one fast-spreading emollient, at least one medium-spreading emollient, and at least one slow-spreading emollient during the formation of the compositions to produce compositions that are non-greasy and / or non-bleaching.

[0014] This disclosure also relates to methods for enhancing the sensory properties when applying to the skin a composition comprising at least one physical ultraviolet (UV) attenuating material, wherein the method includes adding at least one fast-spreading emollient, at least one medium-spreading emollient, and at least one slow-spreading emollient to a composition comprising at least one physical ultraviolet (UV) attenuating material during the formation of the composition in sufficient quantities to enhance the sensory properties of the composition when applied to the skin.

[0037] “UV protection efficiency” or “filtration efficiency” in the context of This disclosure is evaluated based on one or more of the following: FPS, FPUVA, critical wavelength, and UVA-I / UV ratio.

[0038] The "SPF" (Sun Protection Factor) measures the level of protection against erythema caused by a composition. The SPF value corresponds to the ratio between the minimum erythematous dose (MED) measured on skin covered with the composition and the MED measured on bare skin. The term "SPF" is well known in the field of sunscreens 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).

[0039] 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.

[0040] 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).” It can also 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 U.S. Federal Register on May 7, 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.

[0041] “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 the skin color observed 2 to 4 hours after UVA exposure. It can also be determined according to FDA protocols, as described again in 21 CFR Part 352 Subpart D § 352.72 as mentioned above in relation to SPF.

[0042] 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.

[0043] 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 / 2019-03019 / sunscreen-drug-products-for-over-the-counter-human-use.

[0044] According to this disclosure, the compositions in this disclosure preferably have one or more of the following properties:

[0045] The compositions have a critical wavelength, as determined by FDA critical wavelength procedures, of at least 370 nm;

[0046] The compositions have an FPS value of at least 15, preferably at least 30, preferably at least 50 and preferably at least 70;

[0047] The compositions have an FPUVA / FPS ratio of at least 1 / 3, and preferably of at least 2 / 5; and / or

[0048] The compositions have a UVA1 / UV ratio of 0.7 or more, preferably 0.75 or more, and preferably 0.8 or more.

[0049] “Makeup result”, as used herein, refers to compositions where The color remains the same or substantially the same as at the time of application, as observed with the naked eye, after a prolonged period. The "makeup result" can be evaluated by assessing the long-lasting properties using any method known in the art for evaluating such properties. For example, long-lasting performance 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 reassessed and compared after a certain duration. Furthermore, these characteristics can be evaluated in relation to other compositions, such as commercially available compositions.

[0050] “Natural” as in the expression “natural compound” means any compound derived directly from a natural substance such as a plant without having undergone chemical modification.

[0051] “Compound of natural origin” means 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.

[0052] “Synthetic compound” means any compound that is neither a natural compound nor a composed of natural origin.

[0053] “Room temperature” means approximately 20 to 25 °C.

[0054] “Atmospheric pressure” means approximately 760 mmHg, i.e. approximately 105 pascals.

[0055] “UV filter” and “sunscreen agent” are used interchangeably in the present request.

[0056] “UV effectiveness”, “UV effectiveness” and “UV protection effectiveness” are used interchangeably in this application.

[0057] The compositions and processes of the present invention may include, consist of, or essentially consist of the essential elements and limitations of the disclosure described herein, together with any additional or optional ingredients, components, or limitations described herein or otherwise useful. For example, the UV (ultraviolet) absorbing system of the compositions in the disclosure may “consist essentially in » at least one(s) physical material(s) for attenuating ultraviolet (UV).

[0058] For the purposes of this disclosure, the "fundamental and novel property" associated with compositions, components and processes related to UV protection properties that "consist essentially of" identified ingredients or actions is "UVA protection indicated by the FPUVA / FPS and UVA1 / UV ratios"

[0059] For the purposes of this disclosure, the "fundamental novel property" associated with compositions, components and processes related to the properties of the composition when applied to keratinous material that "consist essentially of" identified ingredients or actions means "enhanced sensory properties when applied to the skin".

[0060] “Improvement of sensory properties when applied to the skin” As used here, "sensory properties" refers to the diffusion of sensory properties over time during application to the skin. The most optimal "sensory properties," as used here, refer to compositions that have a pleasant, smooth, and lubricating feel throughout the application of the product to a keratinous substrate. By way of comparison, using only fast-spreading emollients in a composition would result in a composition that provides a pleasant, lubricating sensation only during the initial application and becomes unpleasant for the remainder of the application time. Conversely, using only slow-spreading emollients in a composition would result in a composition that feels heavy and greasy throughout the application.Using only medium-spreading emollients would result in a composition that would not be particularly pleasant or lubricating throughout the application.

[0061] The compositions of this disclosure may be in any form suitable for use as a personal care composition, such as a stick, paste, cream, anhydrous composition, emulsion (oil-in-water, water-in-oil, multiple emulsion such as oil-in-water-in-oil), nanoemulsion, gel, liquid, solid, etc. These compositions may be used for all personal care purposes in cosmetic and / or dermatological products such as, for example, sunscreen, foundation, lip balms, lipsticks, concealers, mascaras, leave-in hair products, eyeshadows, powders, etc.

[0062] Reference is made herein to trade names of materials including, but not limited to, materials such as polymers and optional components. The materials are not intended to be limited by the materials described and referenced by a particular trade name herein. Equivalent materials (for example, those obtained from a different source under a different name or catalogue (reference) number) to those referenced by a trade name may be substituted for and used in the processes described and claimed herein.

[0063] Unless otherwise stated, all percentages and ratios are calculated by weight. Unless otherwise stated, all percentages are calculated relative to the total weight of a composition. All component or composition rates refer to the active rate of that component or composition and are understood to exclude impurities, for example, residual solvents or by-products, which may be present in commercially available sources.

[0188] Unless otherwise stated, all numbers expressing quantities of ingredients, reaction conditions, etc., used in the patent memorandum and claims are to be understood as modified in all cases by the term "approximately." Accordingly, unless otherwise stated, the numerical parameters presented in the following patent memorandum and the attached claims are approximations that may vary depending on the desired properties that are sought to be obtained through this disclosure.

[0189] Although the numerical ranges and parameters defining the general scope of disclosure are approximations, the numerical values ​​shown in the specific examples are reported as accurately as possible. However, every numerical value inherently contains some errors that necessarily result from the standard deviation found in its respective measurements. The following examples are intended to illustrate disclosure without, however, limiting its scope. Percentages are provided on a weighted basis. Example 1 - Sample Formulations

[0191] Mixtures containing 15 wt% zinc oxide, treated with triethoxycaprylylsilane, and 2 wt% polyhydroxystearic acid dispersed in various emollients were prepared as identified in Table 3 below. The mixtures were prepared by mixing under high shear at high temperature (above 50 degrees Celsius) until the zinc oxide material was well dispersed. Transmission values ​​at 650 nm were determined. Such transmission values ​​correspond to the relative whitening effect of the material of zinc oxide in the mixtures, higher values ​​indicating a less white effect.

[0193] The emollient system of this disclosure in Table 1 was prepared using a mixture of a C15-C19 alkane, dicaprylyl carbonate, and cetearyl isononanoate in a relative weight ratio of 7:5:2.5. It was expected that the resulting 650 nm transmission value for this mixture would result from a linear sum of the relative contributions for each emollient. The emollient system under test was therefore expected to produce a transmission value of 42.5. However, it was unexpectedly determined that there was a synergistic relationship for the combination of a fast-spreading emollient, a medium-spreading emollient, and a slow-spreading emollient that gave a transmission value approximately 4 units higher than the expected 650 nm transmission value.
