The present invention relates to the use of a sunscreen or daily care composition comprising certain UV filters for increasing the compatibility of the sunscreen or daily composition with skin microbiome, preferably human skin microbiome. Further, the invention is directed to specific sunscreen or daily care, which are suitable for the microbiome friendly application. Finally, the invention relates to the use of a composition (A) comprising certain UV filters for producing a sunscreen or daily care composition, which is compatible with the skin microbiome, preferably human skin microbiome.
UV radiation causes harmful effects on the human skin. Beside the acute effect of sunburn of the skin, UV radiation is also known to increase the risk of skin cancer. Furthermore, long time exposure to UV-A and UV-B light can cause phototoxic and photo allergenic reactions on the skin and can accelerate skin aging.
To protect the human skin from UV radiation, various sun protecting UV filters (also referred to as UV absorbers) exist including UV-A filter (also referred to as UVA filter), UV-B filter (also referred to as UVB filter) and broadband filters. These filters are added to sunscreen or daily care compositions. The UV filters are either organic or inorganic, particulate or non-particulate compounds, of which all have a high absorption efficacy in the UV-light range. In general, UV light can be divided into UV-A radiation (320-400 nm) and UV-B radiation (290-320 nm). Depending on the position of the absorption maxima, UV filters are divided into UV-A and UV-B filters. In case a UV filter absorbs both, UV-A and UV-B light, it is referred to as a broadband absorber.
Since 2006, the EU commission has recommended that all sunscreen or daily care compositions should have a UV-A protection factor, which is at least one third of the labelled sun protection factor (SPF), wherein the sun protection factor refers mainly to the UV-B protection.
The human skin comprises millions of bacteria, fungi, and viruses that compose the skin microbiome. These organisms have essential roles in e.g. the protection against invading pathogens. When the barrier, which is provided by these organisms, is broken, humans are vulnerable to invading pathogens. It is known that e.g. compounds comprised in cosmetic products tend to break said barrier.
Even if main marketed products are providing both UVB and UVA protection according to the current standards, there is a need for improvement of the skin microbiome friendliness of e.g. sunscreens. Skin microbiome friendliness is an important performance indicator for end consumers, since users exemplarily need UV protection while parallel remaining a well-balanced skin microbiome. In addition, a lot of sunscreen or daily care compositions contain UV filters and other ingredients such as dispersing agents, which are frequently under discussion due to some concerns on human safety and skin sensitization potential, especially for a daily use, although they are approved for being used in leave-on compositions.
Against this background, there is an ongoing need for sunscreen or daily care compositions for the daily use, which provide efficient sun protection and provide a well-balanced skin microbiome. In particular, it was an object of the present invention to provide a sunscreen or daily care composition comprising a microbiome friendly UV filter. It was further an object of the present invention to provide a microbiome friendly sunscreen or daily care composition. Further, it was an object to provide a sunscreen or daily care composition comprising a UV filter for use in a method of increasing the compatibility of the sunscreen or daily care composition comprising with the skin microbiome. Further, it was an object of the present invention to provide a method of producing a skin microbiome friendly sunscreen or daily care composition. Finally, it was an object of the present invention to provide a composition (A) comprising a UV filter for the method of producing a skin microbiome friendly sunscreen or daily care composition.
It has surprisingly been found that at least one of these objects can be achieved by the sunscreen or daily care compositions and/or the compositions according to the present invention.

Before describing in detail exemplary embodiments of the present invention, definitions which are important for understanding the present invention are given.
As used in this specification and in the appended claims, the singular forms of “a” and “an” also include the respective plurals unless the context clearly dictates otherwise. In the context of the present invention, the terms “about” and “approximately” denote an interval of accuracy that a person skilled in the art will understand to still ensure the technical effect of the feature in question. The term typically indicates a deviation from the indicated numerical value of ±15%, preferably ±10%, more preferably ±5%, even more preferably ±2%. It is to be understood that the term “comprising” is not limiting. For the purposes of the present invention the term “consisting of” is considered to be a preferred embodiment of the term “comprising of”. If hereinafter a group is defined to comprise at least a certain number of embodiments, this is meant to also encompass a group which preferably consists of these embodiments only. Furthermore, the terms “first”, “second”, “third” or “(a)”, “(b)”, “(c)”, “(d)” etc. and the like in the description and in the claims, are used for distinguishing between similar elements and not necessarily for describing 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 are capable of operation in other sequences than described or illustrated herein. In case the terms “first”, “second”, “third” or “(a)”, “(b)”, “(c)”, “(d)”, “i”, “ii” etc. relate to steps of a method or use or assay there is no time or time interval coherence between the steps, i.e. the steps may be carried out simultaneously or there may be time intervals of seconds, minutes, hours, days, weeks, months or even years between such steps, unless otherwise indicated in the application as set forth herein above or below. It is to be understood that this invention is not limited to the particular methodology, protocols, reagents etc. 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 present invention that will be limited only by the appended claims. Unless defined otherwise, all technical and scientific terms used herein have the same meanings as commonly understood by one of ordinary skill in the art.
As used herein the term “does not comprise”, “does not contain”, or “free of” means in the context that the composition of the present invention is free of a specific compound or group of compounds, which may be combined under a collective term, that the composition does not comprise said compound or group of compounds in an amount of more than 0.8% by weight, based on the total weight of the composition. Furthermore, it is preferred that the composition according to the present invention does not comprise said compounds or group of compounds in an amount of more than 0.5% by weight, preferably the composition does not comprise said compounds or group of compounds at all.
When referring to compositions and the weight percent of the therein comprised ingredients it is to be understood that according to the present invention the overall amount of ingredients does not exceed 100% (±1% due to rounding).
The term “sunscreen composition” or “sunscreen” refers to any topical product, which absorbs and which may further reflect and scatter certain parts of UV radiation. Thus, the term “sunscreen composition” is to be understood as not only including sunscreen compositions, but also any cosmetic compositions that provide UV protection. The term “topical product” refers to a product that is applied to the skin and can refer, e.g., to sprays, lotions, creams, oils, foams, powders, or gels. According to the present invention the sunscreen composition may comprise one or more active agents, e.g., organic and inorganic UV filters, as well as other ingredients or additives, e.g., emulsifiers, emollients, viscosity regulators, stabilizers, preservatives, or fragrances.
The term “daily care composition” refers to any topical product, which absorbs and which may further reflect and scatter certain parts of UV radiation and is used as an everyday care product for the human body, e.g. for face or body. The daily care composition may comprise one or more active agents, e.g., organic and/or inorganic UV filters, as well as other ingredients or additives, e.g., emulsifiers, emollients, viscosity regulators, stabilizers, preservatives, or fragrances. Suitable daily care composition are according to the present invention, e.g. leave-on face and body care products.
Suitable leave-on products for face and body are, e.g. sunscreen compositions, decorative preparations, and skin care preparations.
Suitable decorative preparations are, e.g., lipsticks, nail varnishes, eye shadows, mascaras, dry and moist make-up, rouge, powders, depilatory agents and suntan lotions.
Suitable skin care preparations are e.g., moisturizing, refining, and lifting preparations. The cited daily care compositions can be in the form of creams, ointments, pastes, foams, gels, lotions, powders, make-ups, sprays, sticks or aerosols.
The term “UV filter” or “ultraviolet filter” as used herein refers to organic or inorganic compounds, which can absorb and may further reflect and scatter UV radiation caused by sunlight. UV-filter can be classified based on their UV protection curve as UV-A, UV-B, or broadband filters.
The term “emollient” relates to cosmetic specific oils used for protecting, moisturizing and lubricating the skin. The word emollient is derived from the Latin word mollire, to soften. In general, emollients prevent evaporation of water from the skin by forming an occlusive coating. They can be divided into different groups depending on their polarity index.
The term “polarity index” refers to non-polar or polar oils. Non-polar oils are mainly based on hydrocarbons and lack an electronegative element, such as oxygen. In contrast, polar oils contain heteroatoms that differ in electronegativity, which results in a dipole moment. However, such oils are still insoluble in water, i.e. hydrophobic. The polarity index can be determined by measuring the interfacial tension between the respective oil and water.
The term “sensitive skin” refers to skin of which the natural barrier function is weakened and has broken due to a trigger. A trigger can be for example cold weather, extremely hot water and critical ingredients, which may be included in sunscreen or daily care compositions.
The term “sun protection factor (SPF)” as used herein indicates how well the skin is protected by a sunscreen composition mainly from UV-B radiation. In particular, the factor indicates how much longer the protected skin may be exposed to the sun without getting a sunburn in comparison to untreated skin. For example, if a sunscreen composition with an SPF of 15 is evenly applied to the skin of a person usually getting a sunburn after 10 minutes in the sun, the sunscreen allows the skilled person to stay in the sun 15 times longer. In other words, SPF 15 means that 1/15 of the burning UV radiation will reach the skin, assuming sunscreen is applied evenly at a thick dosage of 2 milligrams per square centimeter (mg/cm2).
The definition of “broadband” protection (also referred to as broad-spectrum or broad protection) is based on the “critical wavelength”. For broadband coverage, UV-B and UV-A protection must be provided. According to the US requirements, a critical wavelength of at least 370 nm is required for achieving broad spectrum protection. The term “critical wavelength” is defined as the wavelength at which the area under the UV protection curve (% protection versus wavelength) represents 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 of the sunscreen composition is not limited to the wavelengths of UV-B, i.e. wavelengths from 290-320 nm, but extends to 370 nm in such a way that 90% of the total area under the protective curve in the UV region are reached at 370 nm.
Furthermore, in Europe, it is recommended by the European Commission that all sunscreen or cosmetic compositions should have a UV-A protection factor, which is at least one third of the labelled sun protection factor (SPF), e.g. if the sunscreen composition has an SPF of 30 the UVA protection factor has to be at least 10.
The term “administration” refers to the application of a sunscreen or daily care composition to the skin of a person.
Preferred embodiments regarding the sunscreen or daily care composition as well as the use thereof (e.g. in a method of increasing the compatibility of the sunscreen or daily composition with skin microbiome) and/or the use of a composition comprising DHHB for producing a sunscreen or daily care composition, which is compatible with the skin microbiome are described hereinafter. It is to be understood that the preferred embodiments of the invention are preferred alone or in combination with each other.
As indicated 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 hexyl 2-[4-(diethylamino)-2-hydroxybenzoyl]benzoate (INCI diethylamino hydroxybenzoyl hexyl benzoate), 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), Terephthalylidene Dicamphor Sulfonic Acid (also known as TDSA), drometrizole trisiloxane (also known as DTS), and mixtures thereof, for increasing the compatibility of the sunscreen or daily composition with skin microbiome, preferably human skin microbiome.
As above-mentioned the skin microbiome comprises numerous organisms, which are important for protecting e.g. mammal (such as humans) against pathogens. It is known that several compounds have a negative effect on said skin microbiome. It is to be understood that “increasing the compatibility of the sunscreen or daily composition with skin microbiome” according to the present invention denotes that the inventive compositions comprising one of the specific UV filters have a superior microorganism population over the exact same composition, which merely does not comprise the specific UV filters. Suitable representatives of a microorganism of the skin microbiome are e.g. Staphylococcus epidermidis, Micrococcus luteus, and Corynebacterium jeikeium.
In connection with the present invention, the following preferred embodiments regarding the sunscreen or daily care composition are relevant. It is to be understood that each preferred embodiment is relevant on its own as well as in combination with other preferred embodiments.
In a preferred embodiment, the UV filter selected from the group consisting of hexyl 2-[4-(diethylamino)-2-hydroxybenzoyl]benzoate (INCI diethylamino hydroxybenzoyl hexyl benzoate), 2,4-Bis-{[4-(2-ethyl-hexyloxy)-2-hydroxy]-phenyl}-6-(4-methoxyphenyl)-1,3,5-triazine (INCI bis-ethylhexyloxyphenol methoxyphenyl triazine), 2-Phenyl-3H-benzimidazole-5-sulfonic acid (INCI Phenylbenzimidazole Sulfonic Acid), Terephthalylidene Dicamphor Sulfonic Acid (TDSA), drometrizole trisiloxane (DTS), and mixtures thereof, increases the compatibility of the sunscreen or daily care composition with the long-term resident human skin microbiota (also known as human skin microbiome) mainly consisting of gram-positive bacteria especially the general Staphylococcus, Corynebacterium, Propionibacterium, Micrococcus, Streptococcus, and Brevibacterium and gram-negative bacteria such as Pseudomonas, as well as yeasts such as the genera Malassezia (former Pityrosporum) or Candida. Especially of relevance for the healthy resident microflora are the species selected from the group consisting of Propionibacterium acnes, Propionibacterium granulosum, Propionibacterium avidum, Staphylococcus epidermidis, Staphylococcus saprophyticus, Staphylococcus hominis, Staphylococcus xylosus, Staphylococcus warneri, Staphylococcus haemolyticus, Staphylococcus saccharolyticus, Staphylococcus conii, Staphylococcus auricularis, Micrococcus luteus, Corynebacterium minutissimum, Corynebacterium jeikeium, Corynebacterium fastidiosum, Corynebacterium simulans, Corynebacterium amycolatum, Corynebacterium xerosis, Streptococcus mitis, Streptococcus sanguinis, Streptococcus oralis, Brevibacterium spp., Pseudomonas spp., Malassezia furfur, Malassezia restricta, Malassezia globosa, Candida spp., and mixtures thereof. It is especially preferred that the compatibility with Staphylococcus epidermidis, Micrococcus luteus, and/or Corynebacterium jeikeium, and in particular with Staphylococcus epidermidis, is increased.
In a preferred embodiment, the UV filter selected from the group consisting of hexyl 2-[4-(diethylamino)-2-hydroxybenzoyl]benzoate (INCI diethylamino hydroxybenzoyl hexyl benzoate), 2,4-Bis-{[4-(2-ethyl-hexyloxy)-2-hydroxy]-phenyl}-6-(4-methoxyphenyl)-1,3,5-triazine (INCI bis-ethylhexyloxyphenol methoxyphenyl triazine), 2-Phenyl-3H-benzimidazole-5-sulfonic acid (INCI Phenylbenzimidazole Sulfonic Acid), Terephthalylidene Dicamphor Sulfonic Acid (TDSA), drometrizole trisiloxane (DTS), and mixtures thereof, increases the compatibility of the sunscreen or daily care composition with the population of bacteria selected from the group consisting of Propionibacterium acnes, Propionibacterium granulosum, Propionibacterium avidum, Staphylococcus epidermidis, Staphylococcus saprophyticus, Staphylococcus hominis, Staphylococcus xylosus, Staphylococcus warneri, Staphylococcus haemolyticus, Staphylococcus saccharolyticus, Staphylococcus conii, Staphylococcus auricularis, Micrococcus luteus, Corynebacterium minutissimum, Corynebacterium jeikeium, Corynebacterium fastidiosum, Corynebacterium simulans, Corynebacterium amycolatum, Corynebacterium xerosis, Streptococcus mitis, Streptococcus sanguinis, Streptococcus oralis, Brevibacterium spp., Pseudomonas spp., and mixtures thereof, on the skin. More preferably, the compatibility with the population of Staphylococcus epidermidis, Micrococcus luteus, and/or Corynebacterium jeikeium, and in particular of Staphylococcus epidermidis, is increased.
In this connection, the meaning of increasing the comparability with skin microbiome is illustrated with Staphylococcus epidermidis as follows:
It is to be understood that the compatibility with skin microbiome of the sunscreen or daily care composition (e.g. of the inventive composition comprising DHHB, BEMT, PBSA, TDSA and/or DTS) is increased if the population of Staphylococcus epidermidis determined after 24 hours is higher than the population of Staphylococcus epidermidis determined after 24 hours of the exact same composition, which merely does not comprise the specific UV filter (e.g. DHHB, BEMT, PBSA, TDSA and/or DTS). Further, it is to be understood that determining the respective Staphylococcus epidermidis population needs to be conducted in an equal manner.
Preferably, the determination of the population is conducted in vitro, wherein a subculture of Staphylococcus epidermidis on tryptic soy agar is suspended in tryptic soy broth and incubated at 36° C. for 24 h (overnight culture). The formulations to be tested are contaminated (TO) with the bacterial suspension (dilution of overnight culture of S. epidermidis in sodium chloride). At 24 h contact, each sample is spread out on the surface of tryptone soy agar plates and incubated for two days at 36° before microbial enumeration.

The sunscreen formulation to be tested was applied on the PMMA plate with an amount of 1.2 mg/cm2. Three plates and 5 measurements per plate were done per formulation. The formulation was distributed manually as equal as possible on the plate. The plates applied with formulation were stored 30 minutes at room temperature and in a dark place prior the measurement.
In vitro transmission measurement were performed from 290-400 nm with 1 nm steps prior to any UV irradiation with the Labsphere UV Transmittance Analyzer UV 2000S. The initial UV transmission spectrum was acquired and the SPF in vitro values were calculated before irradiation (mean SPF of all 15 values (from the three plates and 5 measurements per plate))
A mathematical adjustment of the initial UV spectrum was performed with a coefficient “c” as described in ISO 24443 and the UVA-PF in vitro was calculated before irradiation.
The UV irradiation with Atlas Suntest CPS+ Solar simulator of the formulation was calculated with the UV Dose D as described in ISO 24443.
In vitro transmission measurement after UV exposure and acquisition of the UV transmission spectrum after irradiation were performed. The in vitro SPF value after irradiation was determined. (average of 15 values from the three plates and 5 measurements per plate)
