Abstract
Description
[Technical field]
[0001] The present invention relates to the use of a sunscreen or daily care composition comprising a certain UV-screening agent to increase the compatibility of the sunscreen or daily care composition with the skin microflora, preferably the human skin microflora.Furthermore, the present invention relates to a certain sunscreen or daily care composition suitable for a microflora-friendly application.Finally, the present invention relates to the use of a composition (A) comprising a certain UV-screening agent to produce a sunscreen or daily care composition compatible with the skin microflora, preferably the human skin microflora. [Background technology]
[0002] UV radiation has harmful effects on human skin. It is known that UV radiation increases the risk of skin cancer as well as causing acute effects such as sunburn of the skin. Furthermore, prolonged exposure to UV-A and UV-B light can cause phototoxic and photoallergic reactions in the skin and can accelerate skin aging.
[0003] To protect human skin from UV radiation, there are various sun-protective UV filters (also called UV absorbers), such as UV-A filters (also called UVA filters), UV-B filters (also called UVB filters) and broadband filters. These filters are added to sunscreens or daily care compositions. UV filters are either organic or inorganic particulate or non-particulate compounds, all of which have high absorption efficiency in the UV light range. Generally, UV light can be divided into UV-A radiation (320-400 nm) and UV-B radiation (290-320 nm). UV filters are divided into UV-A filters and UV-B filters according to the position of the absorption maximum. If a UV filter absorbs both UV-A and UV-B light, it is called a broadband absorber.
[0004] Since 2006, the European Commission has recommended that all sunscreen or daily care compositions should have a UV-A protection factor (SPF) of at least one third of the declared SPF (the sun protection factor mainly refers to UV-B protection).
[0005] Human skin contains millions of bacteria, fungi and viruses that constitute the skin microbiome. These organisms play an essential role in defense against, for example, invading pathogens. If the barrier provided by these organisms is destroyed, humans become vulnerable to invading pathogens. For example, it is known that compounds contained in cosmetics tend to destroy said barrier.
[0006] The major products on the market, even if they provide both UVB and UVA protection according to the current standards, are required to improve, for example, the skin microbiota friendliness of sunscreens. Since users typically need to maintain a well-balanced skin microbiota in parallel with UV protection, the skin microbiota friendliness is an important performance indicator for the end consumer. In addition, many sunscreen or daily care compositions contain UV filters and other ingredients, such as dispersants, which, although approved for use in leave-on compositions, are frequently debated due to some concerns about their safety and possible skin sensitization in humans, especially for daily use. Summary of the Invention [Problem to be solved by the invention]
[0007] Against this background, there remains a need for a sunscreen or daily care composition for daily use that provides efficient sun protection and a well-balanced skin microflora. In particular, it was an object of the present invention to provide a sunscreen or daily care composition comprising a UV-screening agent that does not have a negative effect on the microflora. It was also an object of the present invention to provide a sunscreen or daily care composition comprising a UV-screening agent for use in a method for increasing the compatibility of a sunscreen or daily care composition with the skin microflora. It was also an object of the present invention to provide a method for producing a sunscreen or daily care composition that does not have a negative effect on the skin microflora. Finally, it was an object of the present invention to provide a composition (A) comprising a UV-screening agent for a method for producing a sunscreen or daily care composition that does not have a negative effect on the skin microflora. [Means for solving the problem]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0032] Before describing exemplary embodiments of the present invention in detail, definitions that are important for understanding the present invention are provided.
[0033] As used in this specification and the appended claims, the singular forms "a" and "an" also include the respective plural forms, unless the context clearly dictates otherwise. In the context of the present invention, the terms "about" and "approximately" refer to a margin of accuracy that a person skilled in the art would understand to still ensure the technical effect of the feature in question. This term typically indicates a deviation of ±15%, preferably ±10%, more preferably ±5%, and even more preferably ±2% from the indicated numerical value. The term "comprising" is to be understood as non-limiting. The term "comprising" for the purposes of the present invention is considered to be a preferred embodiment of the term "comprising of". In the following, when a group is defined to include at least a certain number of embodiments, this preferably also means to include a group consisting only of these embodiments. Furthermore, the terms "first", "second", "third" or "(a)", "(b)", "(c)", "(d)" and similar terms in this specification and the appended claims are used to distinguish between similar elements and do not necessarily describe a sequential or chronological order. It is to be understood that the terms so used are interchangeable under appropriate circumstances and that the embodiments of the invention described herein can be performed in other orders than those described or illustrated herein. When terms such as "first", "second", "third" or "(a)", "(b)", "(c)", "(d)", "i", "ii" and the like refer to steps of a method or use or assay, unless otherwise specified in this application, as hereinbefore or hereinafter described, there is no time or consistency between the steps, i.e., the steps may be performed simultaneously or there may be a time interval of seconds, minutes, hours, days, weeks, months or even years between such steps. It is to be understood that the invention is not limited to the particular methodologies, procedures, reagents, and the like described herein, as these may vary. It is also to be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention, which will be limited only by the scope of 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.
[0034] As used herein, the terms "does not comprise", "does not contain" or "free of", in the context that the composition of the invention does not comprise a particular compound or group of compounds (which may be groups combined under a collective term), means that the composition does not comprise said compound or group of compounds in an amount greater than 0.8% by weight based on the total weight of the composition. Furthermore, it is preferred that the composition according to the invention does not comprise said compound or group of compounds in an amount greater than 0.5% by weight, and preferably the composition is completely free of said compound or group of compounds.
[0035] When referring to weight percentages of compositions and ingredients contained therein, it is to be understood that in accordance with the present invention, the total amount of ingredients does not exceed 100% (± 1% rounded off).
[0036] The term "sunscreen composition" or "sunscreen" refers to any topical product that can absorb a certain portion of UV radiation and also reflect and scatter it. Therefore, it should be understood that the term "sunscreen composition" not only includes sunscreen compositions, but also includes any cosmetic composition that provides UV protection. The term "topical product" refers to a product that is applied to the skin, and can refer to, for example, a spray, a lotion, a cream, an oil, a foam, a powder, or a gel. According to the present invention, the sunscreen composition can include one or more active agents, such as organic and inorganic UV filters, and other ingredients or additives, such as emulsifiers, emollients, viscosity modifiers, stabilizers, preservatives, or fragrances.
[0037] The term "daily care composition" refers to any topical product used as a daily care product for the human body, for example, face or body, which can absorb a certain portion of UV radiation and also reflect and scatter it.The daily care composition can contain one or more active agents, for example, organic and / or inorganic UV screening agents, and other ingredients or additives, for example, emulsifiers, emollients, viscosity adjusters, stabilizers, preservatives or fragrances.Suitable daily care compositions are according to the present invention, for example, leave-on face and body care products.
[0038] Leave-on products suitable for the face and body are, for example, sunscreen compositions, decorative preparations and skin care preparations.
[0039] Suitable decorative preparations are, for example, lipsticks, nail varnishes, eye shadows, mascaras, dry and moist make-up products, rouge, powders, depilatories and suntan lotions.
[0040] Suitable skin care preparations are, for example, moisturizing, refining and lifting preparations. The daily care compositions mentioned can be in the form of creams, ointments, pastes, foams, gels, lotions, powders, make-ups, sprays, sticks or aerosols.
[0041] The term "UV filter" or "ultraviolet filter" as used herein refers to an organic or inorganic compound that can absorb and also reflect and scatter UV radiation produced by sunlight. UV filters can be classified as UV-A, UV-B or broadband filters depending on their UV protection curve.
[0042] The term "emollient" refers to certain cosmetic oils used to protect, moisturize and lubricate the skin. The word emollient comes from the Latin mollire, which means to soften. Generally, emollients prevent the evaporation of water from the skin by forming an occlusive coating. They can be divided into different groups according to their polarity index.
[0043] The term "polarity index" refers to non-polar or polar oils. Non-polar oils are mainly based on hydrocarbons and lack electronegative elements such as oxygen. In contrast, polar oils contain heteroatoms with different electronegativities, resulting in a dipole moment. However, this type of oil is still insoluble in water, i.e., hydrophobic. The polarity index can be determined by measuring the interfacial tension between the corresponding oil and water.
[0044] The term "sensitive skin" refers to skin whose natural barrier function is weakened and disrupted by triggers, which can be, for example, cold weather, extremely hot water, and potentially dangerous ingredients contained in sunscreen or daily care compositions.
[0045] The term "sun protection factor (SPF)" as used herein indicates how well a sunscreen composition protects the skin, mainly from UV-B radiation. Specifically, this index indicates how long the protected skin can be exposed to sunlight without sunburn, compared to untreated skin. For example, if a sunscreen composition with SPF 15 is evenly applied to human skin that would normally sunburn after 10 minutes in the sun, the sunscreen will allow the person skilled in the art to stay in the sun for 15 times longer. In other words, SPF 15 refers to a sunscreen that is applied to a thickness of 2 milligrams per square centimeter (mg / cm 2This means that if a 15-fold reduction in UV radiation were to reach the skin, assuming it were applied evenly at a dose of 10 ...
[0046] The definition of "broadband" protection (also called broad spectrum or broad-spectrum protection) is based on the "critical wavelength". To cover the broad band, UV-B and UV-A protection must be provided. According to US requirements, the critical wavelength must be at least 370 nm to achieve broad-spectrum protection. The term "critical wavelength" is defined as the wavelength at which the area under the UV protection curve (protection rate vs. wavelength) is 90% of the total area under the curve in the UV region (290-400 nm). For example, a critical wavelength of 370 nm indicates that the protection provided by the sunscreen composition is not limited to UV-B wavelengths, i.e., 290-320 nm, but extends up to 370 nm, reaching 90% of the total area under the protection curve in the UV region at 370 nm.
[0047] Furthermore, in Europe, the European Commission has recommended that all sunscreen or cosmetic compositions should have a UV-A protection factor of at least one-third of the declared sunscreen protection factor (SPF); for example, if a sunscreen composition has an SPF of 30, the UVA protection factor should be at least 10.
[0048] The term "administering" refers to the application of a sunscreen or daily care composition to human skin.
[0049] In the following, preferred embodiments of sunscreen or daily care compositions and their uses (e.g. in a method for increasing the compatibility of a sunscreen or daily composition with the skin microbiota) and / or the use of a composition comprising DHHB to produce a sunscreen or daily care composition compatible with the skin microbiota are described. It is to be understood that the preferred embodiments of the present invention are preferred both alone and in combination with each other.
[0050] As mentioned above, the present invention relates in one embodiment to the use of a sunscreen or daily care composition comprising a UV filter selected from the group consisting of 2-[4-(diethylamino)-2-hydroxybenzoyl]hexylbenzoate (INCI diethylaminohydroxybenzoylhexylbenzoate), 2,4-bis-{[4-(2-ethyl-hexyloxy)-2-hydroxy]-phenyl}-6-(4-methoxyphenyl)-1,3,5-triazine (INCI bis-ethylhexyloxyphenol methoxyphenyl triazine), phenyl-3H-benzimidazole-5-sulfonic acid (INCI phenylbenzimidazole sulfonic acid), terephthalidenedicamphorsulfonic acid (also known as TDSA), drometrizole trisiloxane (also known as DTS) and mixtures thereof, to increase the compatibility of the sunscreen or daily composition with the skin microflora, preferably with the human skin microflora.
[0051] As mentioned above, the skin microbiota is composed of a great number of organisms that are important for example to protect mammals (such as humans) against pathogens. It is known that some compounds have a negative effect on said skin microbiota. According to the present invention, "increasing the compatibility of a sunscreen or daily composition with the skin microbiota" is understood to mean that a composition according to the present invention that contains one of the given UV-screening agents has a better microbial population than a strictly identical composition that does not contain the given UV-screening agent. Suitable representatives of the microorganisms of the skin microbiota are, for example, Staphylococcus epidermidis, Micrococcus luteus and Corynebacterium jeikeium.
