Description

[0001] The present invention relates to a sunscreen or day care composition comprising butyl methoxydibenzoylmethane, at least one UV filter selected from triazine derivatives, at least one photostabilizer selected from butyl octanol salicylate, benzotriazolyl dodecyl p-cresol, ethylhexyl methoxycrylene, polyester-8, diethylhexyl syringylidenemalonate, trimethoxybenzylidene pentanedione, diethylhexyl 2,6-naphthalene dicarboxylate, condensed ring cyanoacrylate derivatives and polyester-25, wherein the composition does not contain octocrylene and ethylhexyl methoxycinnamate.

[0002] UV radiation causes harmful effects on human skin. In addition to the acute effect of skin sunburn, UV radiation is also known to increase the risk of skin cancer. In addition, prolonged exposure to UV-A and UV-B light may cause phototoxic and photoallergic reactions on the skin and may accelerate skin aging.

[0003] In order to protect human skin from UV radiation, there are various sunscreen UV filters (also referred to as UV absorbers), including UV-A filters, UV-B filters and broadband filters. These filters are added to sunscreen or cosmetic compositions. UV filters are organic or inorganic granular or non-granular compounds, which all have high absorption efficacy within the UV light range. UV light can be divided into UV-A radiation and UV-B radiation generally. Depending on the position of the absorption maximum, UV filters are divided into UV-A and UV-B filters. In the case where a UV filter absorbs both UV-A and UV-B light, it is referred to as a broadband absorber.

[0004] Since 2006, the European Commission has recommended that all sunscreen or cosmetic compositions should have a UV-A protection factor which is at least one third of the labeled sun protection factor (SPF), which primarily relates to UV-B protection.

[0005] However, the UV filters known in the prior art for use in sunscreen or cosmetic compositions have some disadvantages. This refers in particular to the disadvantages of certain UV filters that tend to isomerize upon UV radiation or are unstable in the presence of other UV filters. As a result, those UV filters lose their protective properties and need to be stabilized in the sunscreen or cosmetic composition. A commonly used stabilizer with UV protective properties is, for example, octocrylene. However, there are other compounds that stabilize UV ​​filters in sunscreen or daycare compositions, namely photostabilizers. Therefore, there is a need for sunscreen or cosmetic compositions that provide effective UVA and UVB protection.

[0006] Furthermore, certain disadvantages are involved which are often discussed due to their health and environmental concerns, despite their approval for use in sunscreen or cosmetic compositions. The UV filters in question are, for example, octocrylene or ethylhexyl methoxycinnamate. Therefore, there is a need for sunscreen or cosmetic compositions for daily use which are effective for sun protection in the UV-B and UV-A range but do not contain the UV filters in question.

[0007] WO 2006 / 114381 discloses the use of benzotriazole derivatives for increasing the photostability of UV absorber systems which further comprise organic UV absorbers such as cinnamic esters or dibenzoylmethane derivatives.

[0008] US 2003 / 0180230 A1 relates to topically applicatable sunscreen compositions which contain a dibenzoylmethane compound, at least one UV-screening 1,3,5-triazine compound and a photostabilizing amount of at least one UV-screening amino-substituted 2-hydroxybenzophenone.

[0009] WO 2006 / 034968 A1 discloses the use of stabilizers for improving the stability of cosmetic or dermatological compositions comprising at least one dibenzoylmethane derivative and at least one amino-substituted 2-hydroxybenzophenone derivative.

[0010] US 2003 / 0161793 A1 relates to topically applicatable sunscreen compositions which do not contain any p-methylbenzylidene camphor and contain at least one UV-screening dibenzoylmethane compound and at least one UV-screening amino-substituted 2-hydroxybenzophenone.

[0011] Therefore, an object of the present invention is to provide an effective sunscreen or daily care composition. Another object of the present invention is to provide an effective sunscreen or daily care composition, which perfectly meets the needs of consumers in terms of protection effect and convenience when and after applying the product. In this regard, another object of the present invention is to provide a sunscreen or daily care composition that does not contain certain UV filters in question. Another object of the present invention is to provide a sunscreen or daily care composition that does not contain certain key UV filters in question. In addition, another object of the present invention is to provide a composition suitable for use in a sunscreen or daily care composition to improve the photostability of certain UV filters contained in the composition, especially to improve the photostability of highly effective UV filters contained in the composition.

[0012] It has surprisingly been found that at least one of these objects can be achieved by the sun protection or day care compositions according to the invention.

[0013] The inventors of the present application have found in particular that the sunscreen or daily care composition of the present invention provides effective UV-A and UV-B protection, but the composition does not contain certain UV filters in question, namely octocrylene and ethylhexyl methoxycinnamate. In addition, the inventors of the present application have surprisingly found that the sunscreen or daily care composition of the present invention can be used to improve the photostability of at least one UV filter selected from triazine derivatives.

[0044] Before describing preferred embodiments of the present invention in detail, definitions important for understanding the present invention are given.

[0045] As used in this specification and the appended claims, the singular forms of "a" and "an" also include the corresponding plural forms, unless the context clearly dictates otherwise. In the context of the present invention, the terms "about" and "approximately" represent the precision intervals that a person skilled in the art understands to still ensure the technical effect of the described features. The term generally means a difference of ±20%, preferably ±15%, more preferably ±10%, and even more preferably ±5% from the numerical value shown. It should be understood that the term "comprising" is not restrictive. For the purposes of the present invention, the term "consisting of..." is considered to be a preferred embodiment of the term "comprising". If a group is defined below as comprising at least a certain number of embodiments, this is intended to also include a group that is preferably composed only of these embodiments.

[0046] Furthermore, the terms "first," "second," "third," or "(i)," "(ii)," "(iii)," "(iv)," and the like in the description and claims are used to distinguish between similar elements and not necessarily to 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 are capable of operation in other sequences than described or illustrated herein.

[0047] As used herein, the term "free of" in the context of a composition according to the invention not containing a specific compound or a specific group of compounds that may be combined under a collective term means that the composition does not contain said compound or said 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 contain said compound or said group of compounds in an amount greater than 0.5% by weight, preferably the composition does not contain said compound or said group of compounds at all. The same definition applies to the term "free of".

[0048] In addition, it should be understood that the term "free of" or "does not contain" means that the composition does not contain compound X. and In the case of compound Y, it means that the composition must not contain both compounds X and Y. In other words, the composition may not contain any compound selected from X and Y.

[0049] The term "sunscreen composition" relates to any topical product that reflects and / or absorbs a certain portion of the UV radiation. Thus, the term "sunscreen composition" is to be understood as including not only sunscreen compositions, but also any cosmetic composition that provides UV protection. The term "topical product" relates to a product that is applied to the skin and may, for example, relate to a spray, a lotion, a cream, an oil or a gel. The sunscreen composition may comprise one or more active agents, such as organic or inorganic UV filters, and other ingredients or additives, such as emulsifiers, emollients, viscosity modifiers, stabilizers, preservatives or fragrances.

[0050] The term "daily care composition" relates to any topical product which reflects and / or absorbs a certain portion of the UV radiation and is used as a daily care product for the human body, such as the face, body or hair. The daily care composition may comprise one or more active agents, such as organic or inorganic UV filters, and other ingredients or additives, such as emulsifiers, emollients, viscosity regulators, stabilizers, preservatives or fragrances.

[0051] As used herein, the term "sun protection factor (SPF)" indicates how well a sunscreen composition protects the skin primarily against UV-B radiation. The factor indicates, among other things, how much longer the protected skin can be exposed to sunlight without getting burned, compared to untreated skin. For example, if a sunscreen composition with an SPF of 15 applied evenly to human skin typically gets burned after 10 minutes in the sun, then the sunscreen allows a skilled artisan to stay in the sun 15 times longer. In other words, SPF 15 means that 1 / 15 of the sunburning UV radiation hits the skin, assuming that the sunscreen is applied at 2 mg / cm2 (mg / cm 2 ) in large doses evenly administered.

[0052] The term "UV filter" as used herein relates to organic or inorganic compounds that can absorb and / or reflect UV radiation caused by sunlight. UV filters can be classified as UV-A, UV-B or broadband filters based on their UV protection curve. In the context of the present invention, broadband filters can be listed as UV-A filters, because they also provide UV-A protection. In other words, preferred UV-A filters also include broadband filters.

[0053] The term "soluble UV filters" relates to UV filters whose solubility in the aqueous or oily phase is at least 2% by weight, preferably at least 3% by weight, more preferably at least 5% by weight.

[0054] Particulate UV filters can be further divided into organic particulate UV filters and inorganic particulate UV filters. Organic particulate UV filters are based on organic compounds, while inorganic particulate UV filters are based on inorganic compounds such as titanium dioxide. In the sunscreen composition, the particulate UV filters are present in particulate form, since their solubility in the sunscreen composition, i.e. in the water and cosmetic oils contained therein, is less than 0.01% by weight, preferably less than 0.05% by weight. Preferably, the particulate UV filters have a particle size D N 50 is less than 2000 nm, preferably less than 1000 nm, as determined by light scattering, wherein D N 50 relates to the particle size value at which half of the total number lies below this value and half of the total number lies above this value, ie the median value of the particle size volume distribution.

[0055] 1-(4-(1,1-dimethylethyl)phenyl)-3-(4-methoxyphenyl)-1,3-propanedione (INCI BUTYL METHOXYDIBENZOYLMETHANE) is a soluble organic UV-A filter. It absorbs UV-A radiation in the range of 320-400 nm with an absorption maximum at 357 nm.

[0056] Ethylhexyl 2-cyano-3,3-diphenylacrylate (INCI Octocrylene) is an oil-soluble organic UV-B filter with an absorption maximum at 302 nm. It provides broad UV-B absorbance and is known to be an effective stabilizer of photolabile UV filters. Octocrylene is marketed by BASF under the trade name N 539T sales.

[0057] (2E)-2-Ethylhexyl 3-(4-methoxyphenyl)acrylate (INCI Ethylhexyl Methoxycinnamate) is a colorless, odorless UV-B filter with an absorption maximum at 310 nm. It is a good solvent for other crystalline UV filters. Ethylhexyl methoxycinnamate is commercially available from BASF under the trade name MC 80 for sale.

[0058] The term "light stabilizer" relates to an organic compound that prevents a UV filter from undergoing degradation processes upon UV irradiation or from being destabilized by the presence of other compounds, which may be, for example, another UV filter. Light stabilizers protect the UV filters by structural or geometrical means or by dissipating energy from the UV filters to reduce the possibility of destabilization.

[0059] Butyloctanol salicylate is a synthetic ester of salicylic acid and 2-butyloctanol. It is manufactured by Hallstar under the brand name HallBrite Next sales.

[0060] Benzotriazolyl dodecyl p-cresol is produced by BASF under the brand Sold under TL.

[0067] The term "fused ring cyanoacrylate derivative" refers to the compound "Micah" supplied by Hallstar. This compound is based on the following structural formula:

[0068]

[0069] In the context of this application, the compound "Micah" belongs to the group of light stabilizers.

[0070] The term "parabens" relates to a class of preservatives used in cosmetic and pharmaceutical compositions. They are generally used for their bactericidal and fungicidal properties. The chemical structure of parabens is based on parabens or esters of parahydroxybenzoic acid, such as methylparaben, ethylparaben, propylparaben, butylparaben or heptylparaben.

[0071] The term "emollient" relates to cosmetic preparations used to protect, moisturize and lubricate the skin. The word emollient is derived from the Latin word mollire, ie to soften. Emollients generally prevent evaporation of water from the skin by forming an occlusive coating.

[0072] The definition of "broadband" protection (also called broad spectrum or extensive protection) is based on a "critical wavelength". For broadband coverage, UV-B and UV-A protection must be provided. According to US requirements, a critical wavelength of at least 370 nm is required to achieve broad spectrum protection. In addition, the European Commission recommends that all sunscreen or cosmetic compositions should have a UVA protection factor that is at least one third of the labeled sun protection factor (SPF), e.g. if a sunscreen composition has an SPF of 30, the UVA protection factor must be at least 10.

[0466] For the purposes of the present invention, the following preferences are relevant with regard to the use of the sunscreen or day care compositions according to the embodiments listed above.

[0467] As indicated above, the present invention relates in one embodiment to the use of a sunscreen or day care composition as defined above for increasing the photostability of the at least one UV filter chosen from triazine derivatives.

[0468] In this context it is understood that increasing the photostability of the at least one UV filter selected from triazine derivatives means that the at least one UV filter selected from triazine derivatives is stabilized by the photostabilizer compound in such a way that degradation of the UV filter selected from triazine derivatives is prevented upon UV irradiation. Increasing the photostability of the at least one UV filter selected from triazine derivatives can be measured by the recovery of the at least one UV filter selected from triazine derivatives after a certain irradiation duration via HPLC measurement.

[0469] The skilled person knows that BMDBM is a commonly used UV absorber, which tends to isomerize under radiation to produce a triplet diketone. The diketone is very likely to undergo photolysis, which leads to the degradation of BMDBM. In addition, it has been found that the presence of BMDBM makes UV filters selected from triazine derivatives, i.e. ethylhexyl triazone, diethylhexyl butyramido triazone, terphenyl triazine and di-ethylhexyloxyphenol methoxyphenyl triazine unstable. Therefore, it is necessary to add a stabilizer to the composition containing BMDBM, for example, a light-stable UV absorber such as octocrylene is usually used. Therefore, the inventors of the present invention surprisingly found that in the composition of the present invention comprising BMDBM and a UV filter selected from triazines, the triazine derivative can be stabilized by the light stabilizer of the present invention in a sunscreen composition that does not contain octocrylene. In other words, this means that the presence of the light stabilizer of the present invention improves the light stability of the UV filters, i.e. BMDBM and unstable triazine derivatives, present in the sunscreen or daily care composition of the present invention.

[0470] The present invention is further illustrated by the following examples. Example
