Description

Technical Field

[0001] This invention relates to a sunscreen or daily care composition comprising: (i) disopyroxypentaerythritol distearate citrate; and (ii) at least one organic UV filter. Furthermore, this invention relates to the use of disopyroxypentaerythritol distearate citrate in improving the sun protection factor (SPF) and water resistance of sunscreen or daily care compositions comprising at least one organic UV filter, and the corresponding method of application. Background Technology

[0002] UV radiation has harmful effects on human skin. In addition to the acute effects of sunburn, UV radiation is known to increase the risk of skin cancer. Furthermore, prolonged exposure to UVA and UVB light can cause phototoxicity and photosensitivity reactions on the skin and may accelerate skin aging.

[0003] To protect human skin from UV radiation, various sunscreen UV filters (also known as UV absorbers) exist, including UVA filters, UVB filters, and broadband filters. Broadband filters are UV filters that absorb radiation within a wavelength range covering both UVA and UVB. All of these UV filters can be organic or inorganic, particulate or soluble compounds, and are widely used in sunscreens and everyday care compositions with UV protection.

[0004] However, while a wide variety of UV filters have been known and used in the past, many of these filters have become controversial in recent years due to toxicological or environmental reasons. Developing sunscreens that are free of these UV filters while maintaining a high SPF and other desired properties, such as water resistance, is challenging. In many cases, extensive reformulation is required, and efforts are underway to develop new sunscreen formulations that meet regulatory requirements while providing the same properties that consumers are accustomed to and expect.

[0005] Therefore, there is a need for novel personal care compositions that offer excellent SPF and good water resistance without requiring any of the organic UV filter substances currently facing toxicological or environmental concerns.

[0006] This invention addresses this need by providing a personal care composition that combines a high SPF value with excellent water resistance. Summary of the Invention

[0007] This invention is based on the following unexpected discovery by the inventors: by including a specific wax (i.e., disodium palmitoyl pentaerythritol distearate citrate) in personal care compositions, key properties of the formulation, particularly SPF and water resistance, are advantageously affected (i.e., increased). Particularly unexpectedly, disodium palmitoyl pentaerythritol distearate citrate, although it does not possess any sun protection effect on its own, significantly improves the SPF of the organic UV filter in which it is combined.

[0034] Before describing the preferred embodiments of the present invention in detail, definitions that are important for understanding the present invention are given.

[0035] As used in this specification and the appended claims, unless the context clearly indicates otherwise, the singular form “a / an” also includes the corresponding plural form.

[0036] In the context of this invention, the terms "about" and "approximately" indicate a range of precision that, as will be understood by those skilled in the art, still ensures the technical effect of the features discussed. These terms typically indicate a deviation from the indicated value of ±20%, preferably ±15%, more preferably ±10%, and even more preferably ±5%.

[0037] It should be understood that the term "comprising" is not limiting. For the purposes of this invention, the term "consisting of" is considered a preferred embodiment of the term "composed of". If a group is defined below as including at least a certain number of embodiments, this means that a group preferably consisting only of those embodiments is also covered.

[0038] Furthermore, the terms “first,” “second,” “third,” or “(i),” “(ii),” “(iii),” “(iv),” etc., used in the specification and claims are used to distinguish similar elements and are not necessarily used to describe a sequential or chronological order. It should be understood that such terms are interchangeable where appropriate, and the embodiments of the invention described herein can operate in orders other than those described or shown herein.

[0039] As used herein, the term "free from" in the context of the compositions of the invention being free from a specific compound or group of compounds (which may be grouped under a certain set of terms) means that the composition does not contain more than 0.2 wt.% of said compound or group of compounds based on the total weight of the composition. Furthermore, it is preferred that the compositions according to the invention do not contain more than 0.1 wt.% of said compound or group of compounds, and preferably the composition does not contain said compound or group of compounds at all. The same definition applies to the term "not containing". Furthermore, it should be understood that in the case where the composition does not contain compounds X and Y, the term "free from" or "not containing" means that the composition must be free from both compounds X and Y. In other words, the composition may not contain any compound selected from X and Y.

[0040] When referring to a composition and the weight percentage of its constituent components, it should be understood that, according to the invention, the total amount of the components does not exceed 100% (± 1%, due to rounding). If the given numerical value has no decimal places, the corresponding value includes the range resulting from normal rounding. For example, the value 10 thus includes the range of 9.5 to 10.4. This also applies if the number is given relative to the next decimal place. For example, the value 0.5 thus covers the range of 0.45 to 0.54.

[0041] It should be understood that the present invention is not limited to the specific methods, schemes, reagents, etc., described herein, as these can vary. It should also be understood that the terminology used herein is for the purpose of describing specific embodiments only and is not intended to limit the scope of the invention, which will be limited only by the appended claims. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art.

[0042] The term "sunscreen composition" refers to any topical product that absorbs and can further reflect some portion of UV radiation. Therefore, the term "sunscreen composition" should be understood to include not only sunscreen compositions but also any cosmetic composition that provides UV protection. The term "topical product" refers to a product applied to the skin and can refer to, for example, sprays, lotions, creams, oils, gels, sticks, or foams. Sunscreen compositions may contain one or more active agents, such as organic or inorganic UV filters, as well as other ingredients or additives, such as emulsifiers, emollients, viscosity modifiers, stabilizers, humectants, film-forming agents, UV-scattering compounds, UV enhancers, pH adjusters, preservatives, moisturizers, anti-aging active ingredients, vitamins, or fragrances.

[0043] The sunscreen composition of the present invention can be formulated as a water-in-oil or oil-in-water dispersion, or an oil or oil-alcohol mixture, or a vesicle dispersion of ionic or nonionic amphiphilic lipids, or a gel, or a solid rod, or an aerosol formulation.

[0044] The term "daily care composition" refers to any topical product that absorbs and can further reflect and scatter UV radiation on certain parts of the body and is used as a daily care product for the human body (e.g., face or body). Daily care compositions may contain one or more active agents, such as organic and / or inorganic UV filters, as well as other ingredients or additives, such as emulsifiers, emollients, viscosity modifiers, stabilizers, humectants, film-forming agents, UV scattering compounds, UV enhancers, pH adjusters, preservatives, moisturizers, anti-aging active ingredients, vitamins, or fragrances.

[0045] According to the present invention, suitable daily care compositions are, for example, leave-on facial and body care products.

[0046] Suitable leave-on facial and body products include, for example, makeup preparations and skin care preparations.

[0047] Suitable makeup products include, for example, lipstick, nail polish, eyeshadow, mascara, dry and wet cosmetics, blush, powder, hair removal products, and sunscreen.

[0048] Suitable skin care preparations include, for example, moisturizing, improving, and lifting preparations. The listed daily care compositions may be in the form of creams, ointments, pastes, foams, gels, emulsions, powders, cosmetics, sprays, sticks, or aerosols.

[0049] As used herein, the term "discoyl pentaerythritol distearate citrate" is C40328-22-2 with CAS number 130328-22-2. 12-18The INCI name of a mixed ester of fatty acids, citric acid, pentaerythritol, and stearyl alcohol. The compound is commercially available, for example, from BASF SE under the trade name Cutina® Shine.

[0050] As used herein, the term "UV filter" refers to an organic or inorganic compound that can absorb or reflect UV radiation caused by sunlight. UV filters can be classified as UVA filters, UVB filters, or broadband filters based on their UV absorption protection curves. Preferably, the term "UV filter" includes any UV filter or a component thereof as defined in Annex VI of Regulation (EC) 1223 / 2009 of the European Parliament (version of November 11, 2022).

[0051] The definition of “broadband” protection (also known as broad-spectrum or wide-range protection) is based on, for example, a “critical wavelength.” For broadband coverage, both UVB and UVA protection must be provided. According to US and European requirements, a critical wavelength of at least 370 nm is needed to achieve broad-spectrum protection. Furthermore, in Europe, the European Commission recommends that all sunscreens should have a UVA protection factor that is at least one-third of the sun protection factor (SPF); for example, if a sunscreen composition has an SPF of 30, then the UVA protection factor must be at least 10.

[0052] The term "critical wavelength" is defined as a wavelength at which the area of ​​the UV absorption spectrum (relative to the percentage of protection by absorption) accounts for 90% of the total area of ​​the absorption spectrum in the UV region (290-400 nm). For example, a critical wavelength of 370 nm indicates that the protection of a sunscreen composition is not limited to the wavelength of UVB (i.e., the wavelength of 290-320 nm), but extends to 370 nm, such that 90% of the total area of ​​the absorption spectrum in the UV region is reached at 370 nm.

[0053] As used herein, the term "Sun Protection Factor (SPF)" indicates the degree to which a sunscreen composition protects the skin from the appearance of erythema, primarily caused by UVB radiation. Specifically, this factor indicates how long protected skin can be exposed to sunlight without sunburn, compared to unprotected skin. For example, if a sunscreen composition with an SPF of 15 is used at 2 mg / cm²... 2 If applied evenly to the skin of someone who typically gets sunburned after 10 minutes in the sun, this sunscreen allows the person to stay in the sun for 15 times longer. In other words, SPF 15 means that 1 / 15 of the intense UV radiation will reach the skin, assuming a concentration of 2 mg / cm². 2 When the sunscreen is applied evenly in the correct dosage.

[0054] As used herein, “water resistance” refers to the property of a sunscreen product to remain on a surface after contact with water. “Water resistance” can be determined in vitro by spectroscopic measurements and can be based on the procedures described in Sohn et al., Int J Cosmet Sci, “In vitro water resistance testing using SPF simulation based on spectroscopic analysis of rinsed sunscreens”, 2018; DOI:10.1111 / ics.12455. The application of the sunscreen and the water immersion plus rinsing, along with the spectroscopic measurements, can be the same as described in Sohn et al. The sunscreen to be studied was applied at 2 mg / cm³. 2 An amount of the product was applied to a substrate plate made of ethylene methacrylate copolymer (described in Sohn et al., Skin Pharmacol Physiol, “Development of a Synthetic Substrate for the in vitro Performance Testing of Sunscreens”, 2017, 30:159-170). Two sunscreen-coated plates were then immersed in a water bath and kept in the dark at ambient temperature. Following immersion, each of the four plates (two water-immersed and two un-water-immersed) was rinsed with a solvent mixture of THF / ethanol / Neutrol® TE (from BASF Europe) (50:48:2) to recover the UV filter retained on the plates. The solvent / formulation solution was diluted (1:40) and filled into 1 cm quartz cuvettes for UV spectral measurements using a Lambda 20 apparatus in 5 nm increments from 290 to 400 nm. The results were obtained as transmittance data, converted to absorbance values, and the area under the curve (AUC) was calculated from these absorbance values. The AUC was then used to calculate the percentage water resistance (%WR). Unless otherwise indicated, the water resistance referred to herein has been determined according to the described method.

[0055] The “water-soluble UV filter” has a solubility in water of at least 2.0 wt.-%, preferably at least 3.0 wt.-%, more preferably at least 5.0 wt.-%.

[0056] "Oil-soluble UV filter" has the properties of being used in common cosmetic oils (such as benzoic acid C). 12 -C15 Solubility of at least 2.0 wt.-%, preferably at least 5.0 wt.-%, and more preferably at least 7.0 wt.-% in alkyl esters, dibutyl adipate, diisopropyl sebacate, phenethyl benzoate, or dioctyl carbonate.

[0057] The term "insoluble UV filter" refers to a UV filter that is insoluble in water and cosmetic oils at 25°C. These are also referred to herein as "particulate UV filters".

[0058] The inventors of this invention have unexpectedly discovered that the addition of a specific wax compound (i.e., disocoacyl pentaerythritol distearate citrate) enhances the sun protection factor and water resistance of personal care compositions containing UV filters not only relative to the same composition without this wax, but also relative to compositions containing other wax compounds (such as coconut oil glycerides, hydrogenated castor oil, or lauryl laurate).

N 50, of which D N 50 refers to the particle size value, where half of the population is below this value and half is above this value; that is, the median of the particle size distribution.

[0069] The compositions of the present invention may additionally comprise inorganic UV filters. Suitable inorganic UV filters include, but are not limited to, titanium dioxide, zinc oxide, iron oxide, cerium oxide, and mixtures thereof. In various embodiments, the inorganic UV filters can be used as nanomaterials. In this regard, it should be understood that the term "nanomaterial" follows the definition in European Commission Recommendations (2011 / 696 / EU, 2022 / C229 / 01). Thus, in nanomaterials, based on a size distribution of quantity, 50% of the particles are less than 100 nm, which includes constituent particles present in aggregates or agglomerates. In another embodiment of the invention, the inorganic UV filters can be used as non-nanomaterials. Thus, in non-nanomaterials, based on a size distribution of quantity, more than 50% of the particles are greater than 100 nm. Mixtures of nano and non-nano inorganic UV filters can also be used. Furthermore, the inorganic UV filters can be coated or uncoated. If present, titanium dioxide is preferably coated, as uncoated titanium dioxide is photocatalytic and should be avoided in sunscreens. In the context of inorganic UV filters, suitable coatings can be organic and / or inorganic, and are disclosed, for example, in WO 2023 / 036749 A1.

[0420] method

[0421] Water-resistant in vitro solution method

[0422] In vitro water resistance was determined by spectroscopic measurements, based on the findings of Sohn et al., Int J Cosmet Sci, “In vitro water resistance testing using SPF simulation basedon spectroscopic analysis of rinsed sunscreens”, 2018; DOI:10.1111 / ics.12455. The steps of sunscreen application and water immersion, plus rinsing and spectroscopic measurements, were the same as described in Sohn et al.

[0423] Sunscreen application:

[0424] The sunscreen agent under investigation was applied to a 5 cm × 5 cm substrate plate made of ethylene methacrylate copolymer (described in Sohn et al., Skin Pharmacol Physiol, “Development of a Synthetic Substrate for the in vitro Performance Testing of Sunscreens”, 2017, 30:159-170; DOI:10.1159 / 000464471). These conditions should be understood as the most appropriate method currently available for determining the in vitro water resistance of formulations.

[0425] Apply 2 mg / cm to each plate 2 The dosage (corresponding to 50 mg of formulation per plate). A total of four plates were prepared for each sunscreen agent. After the sunscreen agent was applied, followed by a 15-minute equilibration period, two of the four plates were immersed in a water bath and the remaining two plates were kept in the dark at ambient temperature.

[0426] Water immersion conditions

[0427] Using a strip system from Tesa Hook & Loop tape, attach a sunscreen-coated plate to the rim of a 1000-mL beaker (10 cm in diameter) at a defined height. Fill the beaker with 500 mL of distilled water and maintain the temperature at 30°C ± 2°C. Stir the water at 300 rpm for 20 min using a three-bladed impeller equidistant from the attached plate. Then, remove the plate from the empty beaker and allow it to dry at ambient temperature for 30 min before proceeding.

[0428] Spectroscopic measurement and determination of water resistance value

[0429] Following impregnation, each of the four plates (two water-impregnated and two un-water-impregnated) was placed in a separate beaker and washed with 20 mL of a solvent mixture consisting of THF / ethanol / Neutrol® TE (from BASF Europe) (50:48:2). To collect the sunscreen from the plates, each plate was rinsed 10 times with a Pasteur pipette using the same solvent, and the plates were removed from the solvent with tweezers to visually remove all sunscreen residue from the substrate plates. The solvent / formulation solution was diluted (1:40) and filled into 1-cm quartz cuvettes for UV spectral measurements from 290 to 400 nm using a Lambda 20 apparatus in 5 nm steps. Water resistance retention was inferred from the UV transmittance measurements of the corresponding sunscreen solutions obtained from washing the water-impregnated and un-water-impregnated substrate plates. The transmittance data were then converted to absorbance data according to Equation 2:

[0430] A(λ) = -logT(λ)Eq(2)

[0431] Where A(λ) is absorbance and T(λ) is transmittance at wavelength λ.

[0432] Calculated from absorbance data after water immersion ( ) and not soaked in water ( The area under the curve (AUC) of the two plates is used to calculate the percentage of water resistance (%WR).

[0433] Due to the use of different plates to determine and Therefore, %WR is calculated as the ratio between the wetted average and the static average, as described in Equation 3 below:

[0434] .100, Eq(3)

[0435] in It is the average area under the absorbance curves of two plates that have been immersed in water, and It is the average area under the absorbance curves of two plates that have not been soaked in water (dry state).

[0436] In vitro SPF

[0437] In vitro SPF determination is based on the assessment of the UV transmittance of a film of sunscreen sample spread on a rough PMMA plate (SB6 PMMA plate from Creil Helioscreen, France). The sunscreen formulation to be tested was prepared at 1.2 mg / cm². 2Apply the formulation to a PMMA plate. Manually dispense the formulation as evenly as possible onto the plate. Then, before measurement, store the plate with the formulation applied at room temperature (22°C) and in the dark for 30 minutes.

[0438] In vitro transmittance measurements were performed using a Labsphere UV 2000S UV transmittance analyzer from 290 to 400 nm in 1 nm increments. UV transmittance spectra were then acquired, and in vitro SPF (average SPF of all 15 values ​​from three plates, with 5 measurements per plate) was calculated according to the following equation.

[0439]

[0440] in, S(λ) is the erythema spectrum, S(λ) is the spectral irradiance received from the UV source, and T(λ) is the transmittance measured in vitro.

[0441] SPF in body

[0442] In vivo SPF is measured according to standard ISO 24444:2019, which utilizes the skin's erythema response to ultraviolet radiation. In vivo SPF is the ratio of energy required to induce a minimal erythema response when the tested sunscreen product is applied to the skin of a human test subject, with or without application.

[0443] In vivo water resistance

[0444] In vivo water resistance was evaluated by measuring the in vivo SPF (ISO 24444:2019) before and after water immersion, in accordance with standards ISO 16217:2020 and ISO 18861:2020.
