Description
Die vorliegende Erfindung betrifft die Verwendung von Gemischen aus Natriumstearoylglutamat und/oder Cetylstearylsulfat in Kombination mit Glycerylstearat zum Schutze von Ascorbinsäure und/oder generell Ascorbylverbindungen gegen Oxidation, insbesondere in kosmetischen und dermatologischen Zubereitungen. Bevorzugt betrifft die vorliegende Erfindung kosmetische Zubereitungen mit einem wirksamen Schutz vor schädlichen Oxidationsprozessen in der Haut, aber auch zum Schutze kosmetischer Zubereitungen selbst bzw. zum Schutze der Bestandteile kosmetischer Zubereitungen vor schädlichen Oxidationsprozessen. The present invention relates to the use of mixtures of sodium stearoylglutamate and / or cetylstearylsulfate in combination with glyceryl stearate for the protection of ascorbic acid and / or generally ascorbyl compounds against oxidation, in particular in cosmetic and dermatological preparations. Preferably, the present invention relates to cosmetic preparations with effective protection against harmful oxidation processes in the skin, but also for the protection of cosmetic preparations themselves or for the protection of the components of cosmetic preparations from harmful oxidation processes.
Die vorliegende Erfindung betrifft ferner antioxidativ wirksame Wirkstoffkombinationen, bevorzugt solche, welche in hautpflegenden kosmetischen oder dermatologischen Zubereitungen eingesetzt werden. Insbesondere betrifft die Erfindung auch kosmetische und dermatologische Zubereitungen, solche Antioxidantien enthaltend. The present invention further relates to antioxidant active substance combinations, preferably those which are used in skin-care cosmetic or dermatological preparations. In particular, the invention also relates to cosmetic and dermatological preparations containing such antioxidants.
In einer bevorzugten Ausführungsform betrifft die vorliegende Erfindung kosmetische und dermatologische Zubereitungen zur Prophylaxe und Behandlung kosmetischer oder dermatologischer Hautveränderungen wie z.B. der Hautalterung, insbesondere der durch oxidative Prozesse hervorgerufenen Hautalterung. In a preferred embodiment, the present invention relates to cosmetic and dermatological preparations for the prophylaxis and treatment of cosmetic or dermatological lesions, e.g. Skin aging, especially skin aging caused by oxidative processes.
Besonders bevorzugt betrifft die vorliegende Erfindung Wirkstoffe und Zubereitungen, solche Wirkstoffe enthaltend, zum Recycling von oxidiertem Vitamin E, Schutz vor UV-bedingter Hautschädigung (Erythem), Stimulation der Kollagensynthese, Stärkung der dermo-epidermalen Junktionszone (Hautstraffung), sichtbaren Verbesserung des Hautzustandes bei vorzeitiger Hautalterung (Teintverbesserung, Anti-Faltenwirkung), und Stimulation der Ceramidsynthese. The present invention particularly preferably relates to active ingredients and preparations containing such active ingredients for the recycling of oxidized vitamin E, protection against UV-related skin damage (erythema), stimulation of collagen synthesis, strengthening of dermo-epidermal junction zone (skin tightening), visible improvement of the skin condition premature aging of the skin (improvement of the complexion, anti-wrinkle effect), and stimulation of ceramide synthesis.
Die schädigende Wirkung des ultravioletten Teils der Sonnenstrahlung auf die Haut ist allgemein bekannt. Während Strahlen mit einer Wellenlänge, die kleiner als 290 nm ist (der sogenannte UVC-Bereich), von der Ozonschicht in der Erdatmosphäre absorbiert werden, verursachen Strahlen im Bereich zwischen 290 nm und 320 nm, dem sogenannten UVB-Bereich, ein Erythem, einen einfachen Sonnenbrand oder sogar mehr oder weniger starke Verbrennungen. The damaging effect of the ultraviolet part of solar radiation on the skin is well known. While rays with a wavelength less than 290 nm (the so-called UVC range) are absorbed by the ozone layer in the earth's atmosphere, rays in the range between 290 nm and 320 nm, the so-called UVB range, cause erythema simple sunburn or even more or less severe burns.
Als ein Maximum der Erythemwirksamkeit des Sonnenlichtes wird der engere Bereich um 308 nm angegeben. As a maximum of the erythema efficiency of sunlight, the narrower range around 308 nm is given.
Zum Schutz gegen UVB-Strahlung sind zahlreiche Verbindungen bekannt, bei denen es sich um Derivate des 3-Benzylidencamphers, der 4-Aminobenzoesäure, der Zimtsäure, der Salicylsäure, des Benzophenons sowie auch des 2-Phenylbenzimidazols handelt. For protection against UVB radiation, numerous compounds are known, which are derivatives of 3-Benzylidencamphers, 4-aminobenzoic acid, cinnamic acid, salicylic acid, benzophenone and also of 2-phenylbenzimidazole.
Auch für den Bereich zwischen etwa 320 nm und etwa 400 nm, des sogenannten UVA-Bereich, ist es wichtig, Filtersubstanzen zur Verfügung zu haben, da dessen Strahlen Reaktionen bei lichtempfindlicher Haut hervorrufen können. Es ist erwiesen, daß UVA-Strahlung zu einer Schädigung der elastischen und kollagenen Fasern des Bindegewebes führt, was die Haut vorzeitig altern läßt, und daß sie als Ursache zahlreicher phototoxischer und photoallergischer Reaktionen zu sehen ist. Der schädigende Einfluß der UVB-Strahlung kann durch UVA-Strahlung verstärkt werden. Also for the range between about 320 nm and about 400 nm, the so-called UVA range, it is important to have available filter substances, since its rays can cause reactions in photosensitive skin. It has been proven that UVA radiation leads to damage of the elastic and collagenous fibers of the connective tissue, causing the skin to age prematurely, and that it is to be regarded as the cause of numerous phototoxic and photoallergic reactions. The damaging influence of UVB radiation can be amplified by UVA radiation.
Zum Schutz gegen die Strahlen des UVA-Bereichs werden daher gewisse Derivate des Dibenzoylmethans verwendet, deren Photostabilität (
Die UV-Strahlung kann aber auch zu photochemischen Reaktionen führen, wobei dann die photochemischen Reaktionsprodukte in den Hautmetabolismus eingreifen. However, the UV radiation can also lead to photochemical reactions, in which case the photochemical reaction products intervene in the skin metabolism.
Vorwiegend handelt es sich bei solchen photochemischen Reaktionsprodukten um radikalische Verbindungen, beispielsweise Hydroxyradikale. Auch undefinierte radikalische Photoprodukte, welche in der Haut selbst entstehen, können aufgrund ihrer hohen Reaktivität unkontrollierte Folgereaktionen an den Tag legen. Aber auch Singulettsauerstoff, ein nichtradikalischer angeregter Zustand des Sauerstoffmoleküls kann bei UV-Bestrahlung auftreten, ebenso kurzlebige Epoxide und viele andere. Singulettsauerstoff beispielsweise zeichnet sich gegenüber dem normalerweise vorliegenden Triplettsauerstoff (radikalischer Grundzustand) durch gesteigerte Reaktivität aus. Allerdings existieren auch angeregte, reaktive (radikalische) Triplettzustände des Sauerstoffmoleküls. Predominantly, such photochemical reaction products are free-radical compounds, for example hydroxy radicals. Undefined free radical photoproducts that form in the skin itself may show uncontrolled sequelae due to their high reactivity. But also singlet oxygen, a non-radical excited state of the oxygen molecule can occur on UV irradiation, as well as short-lived epoxides and many others. Singlet oxygen, for example, is distinguished from the normally present triplet oxygen (radical ground state) by increased reactivity. However, there are also excited, reactive (radical) triplet states of the oxygen molecule.
Ferner zählt UV-Strahlung zur ionisierenden Strahlung. Es besteht also das Risiko, daß auch ionische Spezies bei UV-Exposition entstehen, welche dann ihrerseits oxidativ in die biochemischen Prozesse einzugreifen vermögen. Furthermore, UV radiation counts as ionizing radiation. There is thus the risk that ionic species may also be formed on exposure to UV radiation, which in turn may intervene oxidatively in the biochemical processes.
Durch all diese Einflüsse ist die Zelle dem sogenannten oxidativen Streß ausgesetzt, unter welchem verstanden wird die Belastung der lebenden Zelle durch Anreicherung zellschädigender oxidierter Verbindungen wie beispielsweise Lipid-Hydroperoxide, Wasserstoffperoxid oder reaktive Sauerstoffverbindungen wie Singulett-Sauerstoff, Hydroxyl, Hyperoxid-Anionen. Der oxidative Streß kann z. B. durch Strahlungs-Einwirkung, Xenobiotika, Schwermetall-Ionen oder andere Ursachen induziert werden. Er spielt eine Rolle bei der Entstehung einiger Erkrankungen. As a result of all these influences, the cell is exposed to the so-called oxidative stress, which is understood as stressing the living cell by accumulation of cell-damaging oxidized compounds such as lipid hydroperoxides, hydrogen peroxide or reactive oxygen compounds such as singlet oxygen, hydroxyl, and peroxide anions. The oxidative stress may, for. B. by radiation exposure, xenobiotics, heavy metal ions or other causes. He plays a role in the development of some diseases.
Zwar besitzt der Körper in begrenztem Maße Abwehrmechanismen gegen den oxidativen Streß. So können mit Hilfe verschiedener Enzym-Aktivitäten [z. B. Superoxid-Dismutase, Peroxidasen wie Glutathionperoxidase (s. Glutathion), Katalase, Caeruloplasmin] das Auftreten reaktiver Radikale verhindert werden. Dies reicht aber oftmals nicht aus und muß, sei es auf kosmetischem oder medizinischem Niveau, Unterstützung erfahren. Although the body has limited defense mechanisms against oxidative stress. Thus, with the help of various enzyme activities [eg. As superoxide dismutase, peroxidases such as glutathione peroxidase (see glutathione), catalase, ceruloplasmin] the occurrence of reactive radicals can be prevented. However, this is often insufficient and must be supported, be it on a cosmetic or medical level.
Um oxidativem Streß vorzubeugen, können den kosmetischen bzw. dermatologischen Formulierungen zusätzliche Antioxidantien und/oder Radikalfänger einverleibt werden. In order to prevent oxidative stress, additional antioxidants and / or radical scavengers can be incorporated in the cosmetic or dermatological formulations.
Zwar sind einige Antioxidantien und Radikalfänger bekannt. So ist bereits in den
An sich vorzügliche Antioxidantien werden gewählt aus der Gruppe der Ascorbinsäure und der Ascorbylverbindungen. In itself excellent antioxidants are selected from the group of ascorbic acid and ascorbyl compounds.
L-Ascorbinsäure {(R)-5-[(S)-1,2-Dihydroxyethyl]-3,4-dihydroxy-5-H-furan-2-on, Vitamin C} zeichnet sich durch die Strukturformel aus. Sie ist leicht löslich in Wasser, gut löslich in Alkohol, unlöslich in Ether, Petrolether, Chloroform, Benzol sowie in Fetten u. fetten Ölen. Ascorbinsäure ist ein Endiol und wirkt als Redukton stark reduzierend. Ascorbinsäure ist wärmeempfindlich und wird insbesondere in Gegenwart von Schwermetallspuren sowie in alkalischem Milieu durch Licht und Luftsauerstoff zersetzt, in reinem, trockenem Zustand ist sie dagegen relativ beständig gegen Licht, Luft und Wärme. L-ascorbic acid {(R) -5 - [(S) -1,2-dihydroxyethyl] -3,4-dihydroxy-5-H-furan-2-one, vitamin C} is characterized by the structural formula out. It is readily soluble in water, readily soluble in alcohol, insoluble in ether, petroleum ether, chloroform, benzene and in fats u. fat oils. Ascorbic acid is an endiol and has a strong reducing effect as a reductone. Ascorbic acid is sensitive to heat and is decomposed in particular in the presence of heavy metal traces and in an alkaline medium by light and atmospheric oxygen, in pure, dry state, however, it is relatively resistant to light, air and heat.
In kosmetischen und dermatologischen Zubereitungen werden anstatt der Ascorbinsäure oftmals Ascorbylverbindungen, bevorzugt Ascorbylester von Fettsäuren, besonders bevorzugt Ascorbylpalmitat eingesetzt, da die Empfindlichkeit dieser Verbindungen auf oxidativen Einfluß gegenüber der Ascorbinsäure stark herabgesetzt ist und diese Verbindungen zumeist besser öllöslich sind, was galenische Vorteile bieten kann. Ascorbyl compounds, preferably ascorbyl esters of fatty acids, particularly preferably ascorbyl palmitate, are often used in cosmetic and dermatological preparations instead of ascorbic acid, since the sensitivity of these compounds to oxidative influence on ascorbic acid is greatly reduced and these compounds are usually better oil-soluble, which can offer galenic advantages.
Ascorbylverbindungen im engeren Sinne sind insbesondere die Ascorbylester der allgemeinen Struktur wobei R einen verzweigten oder unverzweigten Alkylrest mit bis zu 25 Kohlenstoffatomen darstellen kann. Ascorbyl compounds in the narrower sense are in particular the ascorbyl esters of the general structure wherein R may represent a branched or unbranched alkyl radical having up to 25 carbon atoms.
Eine Aufgabe der vorliegenden Erfindung war, die Nachteile des Standes der Technik zu beseitigen. Insbesondere sollten Wirkstoffe bzw. Zubereitungen, solche Wirkstoffe enthaltend, zur Verfügung gestellt werden, bei deren Verwendung eine Stimulation der Kollagensynthese, eine Stärkung der dermo-epidermalen Junktionszone (Hautstraffung) und eine sichtbare Verbesserung des Hautzustandes erzielt werden. An object of the present invention was to eliminate the disadvantages of the prior art. In particular, active ingredients or preparations containing such active ingredients should be made available, in the use of which a stimulation of the collagen synthesis, a strengthening of the dermo-epidermal junction zone (skin tightening) and a visible improvement of the skin condition are achieved.
Es galt dabei galenische Probleme, wie bräunliche Verfärbungen der Formulierung, ein Abbau der enthaltenen lichtempfindlichen Antioxidantien, sowie Hautunverträglichkeiten z.B. durch oxidative Abbauprodukte zu lösen. There were galenic problems, such as brownish discoloration of the formulation, degradation of the light-sensitive antioxidants contained, as well as skin intolerances, e.g. to dissolve by oxidative degradation products.
Es war indes überraschend und für den Fachmann nicht vorherzusehen, daß Zubereitungen, insbesondere kosmetische oder dermatologische Zubereitungen enthaltend

Ferner war nicht vorauszusehen gewesen, daß die erfindungsgemäß verwendeten Wirkstoffkombinationen in kosmetischen oder dermatologischen Zubereitungen höhere Stabilität aufweist als die jeweils einzeln verwendeten Wirkstoffe, was insbesondere die Ascorbylverbindungen und ganz besonders das Vitamin C betrifft. Furthermore, it had not been foreseen that the active ingredient combinations used in cosmetic or dermatological preparations according to the invention have higher stability than each individually used active ingredients, which concerns in particular the ascorbyl compounds and especially the vitamin C.
Erfindungsgemäß ist daher die Verwendung erfindungsgemäßer Wirkstoffkombinationen als Antioxidans sowie seine Verwendung zur Bekämpfung und/oder Prophylaxe der durch oxidative Beanspruchung hervorgerufenen Hautalterung und entzündlicher Reaktionen. According to the invention, therefore, the use of active compound combinations according to the invention as an antioxidant and its use for controlling and / or prophylaxis of the skin aging caused by oxidative stress and inflammatory reactions.
Als besonders vorteilhafte Ausführungsform der vorliegenden Erfindung wird ferner angesehen die Verwendung erfindungsgemäßer Wirkstoffkombinationen zur Bekämpfung und/oder Prophylaxe des oxidativen Stresses. As a particularly advantageous embodiment of the present invention is further considered the use of active compound combinations according to the invention for the control and / or prophylaxis of oxidative stress.
Die erfindungsgemäßen kosmetischen oder dermatologischen Zubereitungen können wie üblich zusammengesetzt sein und zur Behandlung, der Pflege und der Reinigung der Haut und/oder der Haare und als Schminkprodukt in der dekorativen Kosmetik dienen. Sie enthalten bevorzugt 0,001 Gew.-% bis 10 Gew.-%, bevorzugt 0,05 Gew.-% bis 5 Gew.-%, insbesondere 0,1–2,0 Gew.-%, bezogen auf das Gesamtgewicht der Zubereitungen, an erfindungsgemäß verwendeten Wirkstoffkombinationen. The cosmetic or dermatological preparations according to the invention may be composed as usual and used for the treatment, care and cleansing of the skin and / or the hair and as a make-up product in decorative cosmetics. They preferably contain 0.001% by weight to 10% by weight, preferably 0.05% by weight to 5% by weight, in particular 0.1-2.0% by weight, based on the total weight of the preparations, on active compound combinations used according to the invention.
Es ist erfindungsgemäß bevorzugt, den erfindungsgemäß verwendeten Wirkstoffkombinationen bzw. kosmetischen oder dermatologischen Zubereitungen, solche Wirkstoffkombinationen enthaltend Komplexbildner zuzufügen. It is preferred according to the invention to add to the active substance combinations or cosmetic or dermatological preparations used according to the invention, such active substance combinations containing complexing agents.
Komplexbildner sind an sich bekannte Hilfsstoffe der Kosmetologie bzw. der medizinischen Galenik. Durch die Komplexierung von störenden Metallen wie Mn, Fe, Cu und anderer können beispielsweise unerwünschte chemische Reaktionen in kosmetischen oder dermatologischen Zubereitungen verhindert werden. Complexing agents are known auxiliaries of cosmetology or medical galenics. By complexing of interfering metals such as Mn, Fe, Cu and others, for example, unwanted chemical reactions in cosmetic or dermatological preparations can be prevented.
Komplexbildner, insbesondere Chelatoren, bilden mit Metallatomen Komplexe, welche bei Vorliegen eines oder mehrerer mehrbasiger Komplexbildner, also Chelatoren, Metallacyclen darstellen. Chelate stellen Verbindungen dar, in denen ein einzelner Ligand mehr als eine Koordinationsstelle an einem Zentralatom besetzt. In diesem Falle werden also normalerweise gestreckte Verbindungen durch Komplexbildung über ein Metall-Atom od. -Ion zu Ringen geschlossen. Die Zahl der gebundenen Liganden hängt von der Koordinationszahl des zentralen Metalls ab. Voraussetzung für die Chelatbildung ist, daß die mit dem Metall reagierende Verbindung zwei oder mehr Atomgruppierungen enthält, die als Elektronendonatoren wirken. Complexing agents, in particular chelators, form complexes with metal atoms, which in the presence of one or more polybasic complexing agents, ie chelators, represent metallacycles. Chelates are compounds in which a single ligand occupies more than one coordination site on a central atom. In this case, normally stretched compounds are closed by complex formation via a metal atom or ion into rings. The number of bound ligands depends on the coordination number of the central metal. The prerequisite for chelation is that the metal-reactive compound contain two or more atomic groups acting as electron donors.

Die Liste der genannten UVB-Filter, die in Kombination mit den erfindungsgemäßen Wirkstoffkombinationen verwendet werden können, soll selbstverständlich nicht limitierend sein. The list of said UVB filters which can be used in combination with the active compound combinations according to the invention should of course not be limiting.
Gegenstand der Erfindung ist auch die Verwendung einer Kombination der erfindungsgemäß verwendeten Wirkstoffkombinationen mit mindestens einem UVB-Filter als Antioxidans bzw. die Verwendung einer Kombination der erfindungsgemäß verwendeten Wirkstoffkombinationen mit mindestens einem UVB-Filter als Antioxidans in einer kosmetischen oder dermatologischen Zubereitung. The invention also provides the use of a combination of the active substance combinations used according to the invention with at least one UVB filter as antioxidant or the use of a combination of the active compound combinations used according to the invention with at least one UVB filter as antioxidant in a cosmetic or dermatological preparation.
Es kann auch von Vorteil sein, die erfindungsgemäß verwendeten Wirkstoffkombinationen mit UVA-Filtern zu kombinieren, die bisher üblicherweise in kosmetischen Zubereitungen enthalten sind. It may also be advantageous to combine the active ingredient combinations used according to the invention with UVA filters which have hitherto usually been present in cosmetic preparations.
Kosmetische und dermatologische Zubereitungen mit einem wirksamen Gehalt an erfindungsgemäß verwendeten Wirkstoffkombinationen können auch anorganische Pigmente enthalten, die üblicherweise in der Kosmetik zum Schutze der Haut vor UV-Strahlen verwendet werden. Dabei handelt es sich um Oxide des Titans, Zinks, Zirkoniums, Siliciums, Mangans, Cers und Mischungen davon, sowie Abwandlungen, bei denen die Oxide die aktiven Agentien sind. Besonders bevorzugt handelt es sich um Pigmente auf der Basis von Titandioxid. Cosmetic and dermatological preparations with an effective content of active ingredient combinations used according to the invention may also contain inorganic pigments which are commonly used in cosmetics for the protection of the skin from UV rays. These are oxides of titanium, zinc, zirconium, silicon, manganese, cerium and mixtures thereof, as well as modifications in which the oxides are the active agents. Particular preference is given to pigments based on titanium dioxide.
Die EU-Kommission am 22. September 2006 eine Empfehlung veröffentlicht, die für mehr Sicherheit und Transparenz bei Sonnenschutzmitteln sorgen soll. Die EU-Empfehlung sieht einen UVA-Schutz von 1:3 im Verhältnis zum UVB–Schutz vor. On 22 September 2006, the EU Commission published a recommendation aimed at increasing the safety and transparency of sunscreen products. The EU recommendation provides for UVA protection of 1: 3 in relation to UVB protection.
Bislang war lediglich der Schutz von sonnenbrandverursachenden UVB-Strahlen in der Kosmetikverordnung geregelt. Mit der neuen EU–Empfehlung soll jedes Sonnenschutzmittel gleichzeitig auch vor UVA-Strahlung schützen. Der Verbraucher soll davon ausgehen, dass ein UVA-Schutz gewährleistet ist, der mit steigendem SPF-Wert ansteigt. So far, only the protection of sunburn-causing UVB rays was regulated in the Cosmetics Regulation. With the new EU recommendation, each sunscreen should simultaneously protect against UVA radiation. The consumer should assume that UVA protection is guaranteed, which increases with increasing SPF value.
Aus ethischen Gründen wird dazu eine in-vitro-Methode vorgeschlagen. Bei der Beiersdorf AG wurde eine in-vitro Methode zur UVA-Bestimmung in Abhängigkeit an den Lichtschutzfaktor entwickelt: die UVA/UVB-Balance. For ethical reasons, an in vitro method is proposed. Beiersdorf AG developed an in-vitro method for UVA determination as a function of the sun protection factor: the UVA / UVB balance.
Im Februar 2005 wurde die UVA/UVB-Balance als
Eine Methode zur Messung der UVA-Schutzleistung wird derzeit auch bei der COLIPA bearbeitet, weil die Industrie nach einer einheitlichen Methode verlangt. Die COLIPA ist der Dachverband der europäischen Kosmetikindustrie, sie gibt u. a. Empfehlungen hinsichtlich der Ausführung der Messmethode heraus. A method for measuring the UVA protection performance is currently also being worked on at COLIPA because the industry demands a uniform method. The COLIPA is the umbrella organization of the European cosmetics industry. a. Recommendations regarding the execution of the measurement method.
Die UVA/UVB-Balance stellt die Basis der dort diskutierten Methode dar. Sie wird dahingehend modifiziert, dass sie um eine Vorbestrahlung mit UV-Licht erweitert wird, um auch einige spezielle UV-Filtersysteme mit einbeziehen zu können. Bisher wurden die Produkte ohne Vorbestrahlung getestet. The UVA / UVB balance is the basis of the method discussed there. It is modified to include a pre-irradiation with UV light to include some special UV filter systems. So far, the products have been tested without pre-irradiation.
Dadurch konnte kein Aufschluss darüber gegeben werden, ob die Schutzwirkung des Produktes auch unter realen Bedingungen durch Sonneneinwirkung gegeben ist. Diese erweiterte Messmethode trägt den Namen „COLIPA Ratio“. As a result, no information could be provided as to whether the protective effect of the product under real conditions is given by sun exposure. This advanced measurement method is called "COLIPA Ratio".
Das bedeutet, dass UVA-Filter in Relation von 1:3 zu UVB-Filtern eingesetzt werden, und damit der UVA-Schutz mit steigendem Lichtschutz angehoben wird. This means that UVA filters are used in relation of 1: 3 to UVB filters, and thus the UVA protection is increased with increasing light protection.
Erfindungsgemäß ist schließlich ganz besonders bevorzugt, wenn in den Zubereitungen das Verhältnis von UV-A zu UV-B-Schutz, bestimmt nach den Colipa Guidlines Edition 2007a („Method for the in vitro determination of UVA protection provided by sunscreen products“), mindestens 1:3 beträgt, noch vorteilhafter mindestens 2:3 beträgt. Finally, according to the invention, the ratio of UV-A to UV-B protection, determined according to Colipa Guidlines Edition 2007a ("Method for the in vitro determination of UVA protection provided by sunscreen products"), is at least 1: 3, more preferably at least 2: 3.
Die kosmetischen und dermatologischen enthalten Wirkstoffe und Hilfsstoffe, wie sie üblicherweise für diesen Typ von Zubereitungen zur Haarpflege und Haarbehandlung verwendet werden. Als Hilfsstoffe dienen Konservierungsmittel, oberflächenaktive Substanzen, Substanzen zum Verhindern des Schäumens, Verdickungsmittel, Emulgatoren, Fette, Öle, Wachse, organische Lösungsmittel, Bakterizide, Parfüme, Farbstoffe oder Pigmente, deren Aufgabe es ist, die Haare oder die kosmetische oder dermatologische Zubereitung selbst zu färben, Elektroyte, Substanzen gegen das Fetten der Haare. The cosmetic and dermatological ingredients include active ingredients and adjuvants commonly used for this type of hair care and hair treatment preparations. As auxiliaries are preservatives, surface-active substances, substances for preventing the foaming, thickeners, emulsifiers, fats, oils, waxes, organic solvents, bactericides, perfumes, dyes or pigments whose task is the hair or the cosmetic or dermatological preparation itself dye, Elektroyte, substances against the greasing of the hair.
