Description

[0001] BIODEGRADABLE UV ABSORBERS AND USES THEREOF II

[0002] Field of the invention

[0003] The present invention relates to compounds according to formula (I), as defined herein below, that are useful as organic biodegradable UV absorbers, in particular in personal care and pharmaceutical compositions, such as sunscreen and daily care compositions with photoprotection. The present invention furthermore relates to such compositions containing the UV absorbers as well as their corresponding use.

[0004] Background of the invention

[0005] 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. UV radiation is further known to lead to the photolytic degradation of various components in complex mixtures, such as cosmetics, pharmaceuticals, food and beverages, as well as home care and cleaning compositions. Such sensitive ingredients include various colorants that have become more and more important, as they support brand recognition by consumers and avoid cross-contamination by the user in industrial and institutional cleaning applications.

[0006] To protect the human skin from UV radiation, various sun protecting UV filters (also referred to as UV absorbers) exist including UV-A filter, UV-B filter, and broadband filters. These filters are added to e.g. sunscreen or cosmetic compositions. The UV filters are either organic or inorganic, particulate or nonparticulate 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 and UV-B radiation. Depending on the position of the absorption maxima, UV filters are divided into UV-A and UV-B filters. In case an UV filter absorbs both, UV-A and UV-B light, it is referred to as a broadband absorber.

[0007] To protect UV sensitive components and ingredients in cosmetics, pharmaceuticals, food and beverages, as well as home care and cleaning compositions, various light stabilizing agents are known and widely used in the art. However, many of these compounds lack versatility to be used in a wide range of different compositions or have drawbacks related to toxicity, environmental considerations, and legal restrictions. Specifically, the EU ecolabel is used to assure the consumer of a non-toxic and environmentally safe product. As the EU ecolabel is a decisive factor in consumer and customer awareness, it is generally desirable to provide compositions that are non-toxic and environmentally safe which in turn requires that all ingredients are carefully selected to meet the respective legal requirements for such labeling. Consequently, there is need in the field for UV light stabilizers that meet the strict requirements for the EU ecolabel and at the same time provide for the same or even better stabilizing effects than the currently used compounds.

[0008] Achieving a more sustainable chemical industry is generally one of the clear objectives pursued by EU legislation, incorporating the replacement of ingredients having a negative environmental impact such as a negative effect on the endocrine system, persistence, bioaccumulation and or toxicity. In line with these objectives, EU regulations on the use of certain chemicals for some applications become increasingly strict. This is for instance the case for UV filters used in sunscreen applications and UV stabilizers for several other applications.

[0009] Current solutions on the market on the one hand are not fully biodegradable, and on the other hand present toxicity concerns. In fact, the vast majority of (cosmetic) registered organic UV filters are resistant to environmental degradation through chemical, biological, and photolytic processes. Because of their persistence, they bioaccumulate with potential adverse impact on human health and the environment. Due to their wide release into the environment, and especially in the oceans, the demand for biodegradable UV filters is growing.

[0010] In this context, cosmetics product regulations (CPR) will on a noticeably short timescale certainly ban many of the current solutions. In this context and also in view of the increasing importance of the EU ecolabel, innovative and more sustainable (biodegradable) UV filters and UV stabilizer solutions urgently need to be developed and brought to the market to replace current solutions

[0011] The present invention meets this demand by providing novel types of organic UV filters that are more biodegradable than currently used compounds.

[0179] “Industrial and institutional cleaning compositions”, as used herein, relates to cleaning compositions intended for routine cleaning of industrial, commercial, and public institutions, outside of the normal household environment. Examples include, without limitation, cleaning compositions used in industrial (manufacturing) plants, car washes, and dry cleaners.

[0180] The term “light stabilizers” as used herein are compounds suitable for protecting other compounds or compositions against photolytic degradation. The light stabilizer is usually present in such products in a concentration of 50 to 1000 ppm.

[0181] The term “UV-filter” as used herein refers to organic or inorganic compounds, which can absorb 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. Preferably, the term “UV filter” comprises or consists of any UV filter as defined in the Annex VI (version of 11.11.2022) of the Regulation (EC) No 1223 / 2009 of the European Parliament and of the Council.

[0182] The definition of “broadband” protection (also referred to as broad-spectrum or broad protection) may be based for example on the “critical wavelength” or the UVA-PF (UVA protection factor). 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. Furthermore, it is recommended by the European Commission that all sunscreens should have an UVA 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.

[0183] 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.

[0184] The term “photostability” refers to the ability of a UV filter or any other molecule, which is exposed to sunlight, to stay stable upon irradiation. In particular, this means that the compound does not undergo a degradation process upon UV radiation.

[0185] The term “sun protection factor (SPF)” as used herein indicates how well the skin is protected by a sunscreen composition from an erythema (sunburn) induced 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).

[0186] The term “biodegradation” as used herein denotes that microorganism metabolize the material completely to CO₂, energy, water, and biomass in an aerobic process (according to OECD guideline). If not indicated otherwise, biodegradability is assessed herein according to OECD 301 F over a time period of 28 days at 22°C. As used herein, biodegradable includes “partially biodegradable” and “readily biodegradable”. As used herein, if a compound of formula (I) or an organic component of the composition is “partially biodegradable”, this means having a biodegradability of equal to or more than 20% (>20%) but less than 60% (<60%). In particular, partially biodegradable as used herein is defined as >20% but <60% biodegradability as measured by OECD 301 F (BASF screening test) testing.

[0187] As used herein, if a compound of formula (1) or an organic component of the composition is “readily biodegradable”, this means having a biodegradability of larger or equal to 60% (>60%). In particular, readily biodegradable as used herein is defined as >60% biodegradability as measured by OECD 301 F (BASF screening test) testing.

[0188] In general, the biodegradability of an organic component can be assessed via different OECD 301 A-F measurements. With regard to the present invention it is to be understood that the biodegradability has been assessed for compounds of formula (I) according to a measurement of the OECD 301 F testing method defined throughout the present application as OECD 301 F (BASF screening test). The procedure of the OECD 301 F and OECD 301 F (BASF screening test) are described as follows:

[0189] For the principle of the OECD 301 F test reference is made to the OECD Guidelines for the Testing of Chemicals, Section 3, Environmental fate and behavior (doi.org / 10.1787 / 2074577x). A measured volume of inoculated mineral medium, containing a known concentration of test substance (100 mg test substance / L giving at least 50-100 mg ThOD / l; ThOD = theoretical oxygen demand) as the nominal sole source of organic carbon, is stirred in a closed flask at a constant temperature for up to 28 days. The consumption of oxygen is determined either by measuring the quantity of oxygen (produced electrolytically) required to maintain constant gas volume in the respirometer flask, or from the change in volume or pressure (or a combination of the two) in the apparatus. Evolved carbon dioxide is absorbed in a solution of potassium hydroxide or another suitable absorbent. The amount of oxygen taken up by the microbial population during biodegradation of the test substance (corrected for uptake by blank inoculum, run in parallel) is expressed as a percentage of ThOD or, less satisfactorily, COD. ThOD describes the theoretical oxygen demand and COD describes the common oxygen demand.

[0190] OECD 301 F (BASF screening test): Biodegradation in wastewater was tested in triplicate using the OECD 301 F manometric respirometry method. OECD 301 F is an aerobic test that measures biodegradation of a sample by measuring the consumption of oxygen. To a measured volume of medium, 100 mg / L test substance, which is the nominal sole source of carbon is added along with the inoculum (aerated sludge taken from Mannheim waste water treatment plant). This is stirred in a closed flask at a constant temperature of 22 °C for 28 days. The consumption of oxygen is determined by measuring the change in pressure in the apparatus using an OxiTopC. Evolved carbon dioxide is absorbed in a solution of sodium hydroxide. Nitrification inhibitors are added to the flask to prevent usage of oxygen due to nitrification. The amount of oxygen taken up by the microbial population during biodegradation of the test substance (corrected for uptake by blank inoculum, run in parallel) is expressed as a percentage of ThOD (theoretical oxygen demand, which is measured by the elemental analysis of the compound). A positive control Glucose / Glucosamine is run along with the test samples for each cabinet.

[0191] Biodegradation can then be calculated according to the following formula according to the OECD Guideline for the Testing of Chemicals, Section 3

[0192] BOD = (mg O2uptake by test substance – mg O2uptake by blank) / mg test substance in vessel

[0193] % degradation is calculated according to the following formula according to the OECD Guidelines for the Testing of Chemicals, Section 3:

[0194] % degradation = BOD / ThOD x 100

[0195] In this context, the term “organic component” as used above denotes any organic compound, i.e., any compound comprising organic carbon. In the context of the above, this refers to any carbon-containing compound except for the following carbon-containing compounds, which are considered inorganic compounds: carbides, carbonates (salts of carbonic acid characterized by the CO32-anion, and thus not carbonate esters), bicarbonates (salts of carbonic acid characterized by the HCO3-anion), carbonic acid, CO, CO2, and inorganic cyanides (salts characterized by the CN_anion). Further, elemental forms of carbon, such as graphite, diamond, fullerenes, or carbon nanotubes, are not considered organic carbon. Further details of said method can be derived from the examples below.

[0196] Various embodiments regarding the compound of formula (I) as well as the use of the compound of formula (I) to protect skin against UV radiations or as a light stabilizer are described hereinafter. It is to be understood that the preferred embodiments of the invention are preferred alone or in combination with each other. Further, preferred embodiments regarding the cosmetic or pharmaceutical composition comprising a compound of formula (I) as well as the use of such a cosmetic or pharmaceutical composition e.g. in sunscreens are described hereinafter.

[0543] Example 2: Biodegradation

[0544] Biodegradation of the compounds was determined as follows:

[0545] OECD 301 F (BASF screening test): Biodegradation in wastewater was tested in triplicate using the OECD 301 F manometric respirometry method. OECD 301 F is an aerobic test that measures biodegradation of a sample by measuring the consumption of oxygen. To a measured volume of medium, 100 mg / L test substance (i.e. compound of formula (I)), which is the nominal sole source of carbon is added along with the inoculum (aerated sludge taken from Mannheim waste water treatment plant). This is stirred in a closed flask at a constant temperature of 22 °C for 28 days. The consumption of oxygen is determined by measuring the change in pressure in the apparatus using an OxiTopC. Evolved carbon dioxide is absorbed in a solution of sodium hydroxide. Nitrification inhibitors are added to the flask to prevent usage of oxygen due to nitrification. The amount of oxygen taken up by the microbial population during biodegradation of the test substance (corrected for uptake by blank inoculum, run in parallel) is expressed as a percentage of ThOD (theoretical oxygen demand, which is measured by the elemental analysis of the compound). A positive control Glucose / Glucosamine is run along with the test samples for each cabinet.

[0546] Biodegradation can then be calculated according to the following formula according to the OECD Guideline for the Testing of Chemicals, Section 3

[0547] BOD = (mg O2uptake by test substance – mg O2uptake by blank) / mg test substance in vessel

[0548] % degradation is calculated according to the following formula according to the OECD Guidelines for the Testing of Chemicals, Section 3:

[0549] % degradation = BOD / ThOD x 100

[0550] The results are shown in Table 2. Compounds used are shown in Table 3.
