Description

Title of the invention: COMPOSITIONS CONTAINING A UV-ABSORBING SYSTEM INCLUDING A PHYSICAL UV-ATTENUATING MATERIAL, AT LEAST TWO POLYOLS AND AT LEAST ONE AGENT ANIONIC POLYSACCHARIDE THICKENER FIELD OF THE INVENTION

[0001] The present disclosure relates to compositions comprising a UV-absorbing system comprising at least one physical ultraviolet (UV)-attenuating material, at least two polyols and at least one anionic polysaccharide thickening agent, as well as methods of making and using such compositions. DISCUSSION OF THE BACKGROUND

[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, called UVB rays, hinders the development of a natural tan. Exposure is also likely to cause a detrimental change in 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 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 the like.

[0005] In order to obtain a high protection product, 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 preparation of stable compositions with a pleasant texture. It is possible to obtain high UV protection by using one or more organic UV filters; however, Organic UV filters are often very greasy and unpleasant when applied to the skin, especially 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 filters 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 (also known as "white cast") 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 stable composition, particularly in order to achieve a stable, non-greasy, pleasant, non-whitening and high UV protection sunscreen formulation, especially when considering the need to balance the effectiveness of UVA and UVB protection in the presence of a humectant such as polyols.

[0009] There remains a need in the art of improved sunscreen compositions containing a humectant which have high UV protection and balanced UVA and UVB protection, which are stable, non-greasy, pleasant to apply and which are not whitening when applied to the skin.

[0010] Accordingly, one aspect of the present disclosure is a composition containing a humectant that is stable, non-greasy, non-whitening when applied to the skin, and that exhibits high UV protection. Summary of the invention

[0011] This disclosure relates to compositions comprising a UV-absorbing system including at least one physical ultraviolet (UV) attenuating material, at least two polyols, and at least one anionic polysaccharide thickening agent. Preferably, the compositions are stable, non-greasy, and / or non-bleaching (i.e., the compositions do not leave white marks) 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 methods of producing stable compositions comprising at least one ultraviolet (UV) attenuating physical material by combining at least one ultraviolet (UV) attenuating physical material, at least two polyols and at least one anionic polysaccharide thickening agent during the formation of the compositions to produce stable compositions.

[0035] “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.

[0036] 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 erythematous dose (MED) measured on skin covered with the composition and the MED measured on bare skin. "SPF" is a term known in the art 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).

[0037] 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.

[0038] 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.

[0039] “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.

[0040] The evaluation of UVA protection can also be measured in vitro with the Labsphere® spectrophotometer under conditions such as those mentioned above in relation to FPS. The ISO 24443:2021 protocol describes such an in vitro process.

[0041] 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.

[0042] According to this disclosure, the compositions in this disclosure preferably have one or more of the following properties:

[0043] The compositions have a critical wavelength, as determined by FDA critical wavelength procedures, of at least 370 nm;

[0044] The compositions have an FPS value of at least 15, preferably at least 30, preferably at least 50 and preferably at least 70;

[0045] The compositions have an FPUVA / FPS ratio of at least 1 / 3, and preferably of at least 2 / 5; and / or

[0046] The compositions have a UVA1 / UV ratio of 0.7 or more, preferably 0.75 or more, and preferably 0.8 or more.

[0047] “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 re-evaluated and compared after a certain duration. Furthermore, these characteristics can be evaluated in relation to other compositions, such as commercially available compositions.

[0048] “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.

[0049] “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.

[0050] “Synthetic compound” means any compound that is neither a natural compound nor a composed of natural origin.

[0051] “Room temperature” means approximately 20-25 °C.

[0052] “Atmospheric pressure” means about 760 mmHg, i.e. about 105 pascals.

[0053] “UV filter” and “sunscreen agent” are used interchangeably in the present request.

[0054] “Effectiveness against UV”, “UV effectiveness” and “Effectiveness of UV protection” are used interchangeably in this application.

[0055] The compositions and methods of the present invention may include, 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 in the disclosure may "consist essentially of" at least one physical ultraviolet (UV) attenuating material.

[0056] For the purposes of this disclosure, the "fundamental novel property" associated with compositions, components and processes that "consist essentially of" identified ingredients, components or actions is "stability".

[0057] “Stable” or “stability” refers to a composition that has an appearance A homogeneous and smooth appearance (as opposed to perceptible aggregates or lumps) at a specified time, for example, immediately after manufacture (t0), after 4 hours of rest (t4h), and / or after 3 or 23 days of rest (t3d or t23d). Furthermore, or alternatively, "stable" or "stability" refers to a composition that does not undergo phase separation after a specified time (for example, those indicated in the preceding sentence).

[0058] 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 water-in-oil-in-water), 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.

The following examples are intended to illustrate disclosure without, however, limiting its scope. Percentages are provided on a weighted basis. Example 1

[0184] The following compositions were prepared at room temperature (1 kg total quantity) using a Rayneri VMI rotor-stator tool. The aqueous thickening agent was slowly incorporated into the aqueous phase (water, glycerin, and pentylene glycol). After 10 minutes of shearing with the rotor-stator (high shear, 3000 rpm), the ZnO powder was gradually added at the same high shear rate for an additional 20 minutes.

[0185] The stability of the prepared compositions was determined by visual observation, and the viscosity of the prepared compositions was measured at room temperature with a LAMY RM180 rotary viscometer equipped with a movable Ms R 2 immediately after preparation (t0), after 4 hours of rest (t4h), and / or after 3 or 23 days of rest (t3d or t23d) (as shown). The viscosity value was measured after 10 minutes of rotation of the tool in the cup to reach a plateau value, expressed in mPa·s using a lookup curve between the raw data expressed in deviation units (DU) and mPa·s.
