Definitions
- the present invention relates to a cosmetic preparation containing scleroglucan and hydrophilic UV filter substances.
- Emulsions are generally understood to mean heterogeneous systems which consist of two liquids which are immiscible or only partially miscible with one another, which are usually referred to as phases and in which one of the two liquids is dispersed in the other liquid in the form of very fine droplets. Externally and with the naked eye, emulsions appear homogeneous.
- the two liquids are water and oil and if oil droplets are finely distributed in water, then it is an oil-in-water emulsion (O / W emulsion, e.g. milk).
- O / W emulsion oil-in-water emulsion
- the basic character of an O / W emulsion is shaped by the water.
- W / O emulsion water-in-oil emulsion, e.g. butter
- so-called emulsifiers are added to the emulsions.
- Emulsifiers are usually molecules with a polar, hydrophilic structural element and a non-polar, lipophilic structural element.
- a so-called HLB value (a dimensionless number between 0 and 20) is assigned to each emulsifier, which indicates whether the water or oil solubility is preferred. Numbers under 8 indicate oil-soluble, hydrophobic emulsifiers, numbers over 8 indicate water-soluble, hydrophilic emulsifiers.
- the water phase is combined with the lipid phase (oil phase) with stirring, the droplets of the inner phase of the emulsion having to be broken down to a size of less than 10 ⁇ m so that the emulsion becomes stable.
- UVA and UVB filters are summarized in most industrialized countries in the form of positive lists such as Annex 7 of the Cosmetics Ordinance.
- O / W emulsions cosmetic oil-in-water emulsions (O / W emulsions) containing, in addition to a water phase, one or more oil phases dispersed therein as well
- Scleroglucan is released into the surrounding medium as a microbial exopolysaccharide by fungal species of the genus Sclerotium (Basidiomycota, Agariomycetes). Sclerotium delphinii, for example, is a major pest of plants. Scleroglucan is also known as Sclerotium Gum (INCI: Sclerotium Gum).
- Scleroglucan is a (1—> 3; 1—> 6) - ⁇ -D-glucan. Its mean molecular weight is about
- Scleroglucan consists of a linear (1—> 3) - ⁇ -D-glucan chain (O d HioO d OQHIOOd) ⁇ , on which statistically every third glucose unit with a single (1—> 6) - ⁇ -D- Glcp residue is branched.
- Scleroglucan is readily soluble in water and can be used as a thickener.
- the use of scleroglucan in cosmetic emulsions is known per se to the person skilled in the art, but the prior art could not point the way to the present invention.
- DE 10 2014 015 554 discloses the use of scleroglucan in UV filters containing cosmetic preparations to reduce the contamination and / or discoloration of textiles caused by the UV filters in the preparation.
- EP 1 132 076 describes thickened hair compositions containing scleroglucan.
- the emulsion according to the invention is characterized in that the content of scleroglucan in the emulsion is from 0.001 to 5.0% by weight and preferably between 0.01 and 1.5% by weight, particularly preferably between 0.1 and 1.0% by weight, each based on the total weight of the emulsion.
- the emulsion contains one or more oil-in-water emulsifiers (O / W emulsifiers) in a total concentration of 0.05 to 5.0% by weight and preferably in a total concentration of 2.0 to 4.0% by weight, based in each case on the total weight of the emulsion.
- O / W emulsifiers oil-in-water emulsifiers
- the emulsion according to the invention is characterized in that the content of one or more anionic emulsifiers in the emulsion is from 0.001 to 5.0% by weight and preferably between 0.05 and
- the emulsion according to the invention is characterized in that the content of one or more nonionic emulsifiers in the emulsion is from 0.001 to 5.0% by weight and preferably between 0.05 and
- the emulsion according to the invention is characterized in that the content of one or more hydrophilic UV filter substances in the emulsion is from 0.001 to 5.0% by weight and preferably between 0.05 and 3% by weight , particularly preferably between 0.1 and 2% by weight, based in each case on the total weight of the emulsion.
- Advantageous hydrophilic UV-A filter substances for the purposes of the present invention are, for. B. the salts of 2-phenylbenzimidazole-5-sulfonic acid, such as their sodium, potassium or their trietha nolammonium salt, as well as the sulfonic acid itself; also phenylene-1,4-bis (2-benzimidazyl) -3,3'-5,5'-tetrasulfonic acid
- 1,4-di (2-oxo-10-sulfo-3-bornylidenemethyl) benzene and its salts are also advantageous ), which is also known as benzene-1,4-di (2-oxo-3-bornylidenemethyl-10-sulfonic acid) and is characterized by the following structure:
- the emulsion according to the invention is characterized in that hydrophilic emulsifiers with an HLB value of greater than or equal to 8 are used as O / W emulsifiers.
- HLB value of emulsifiers can be found in the usual standard works (e.g. Fiedler, Lexicon of Auxiliaries for Pharmacy, Cosmetics and Neighboring Areas, Editio Cantor Verlag, Aulendorf).
- the emulsion according to the invention is characterized in that, as O / W emulsifiers, glyceryl stearate citrate (CAS 39175-72-9, INCI Glyceryl Stearate Citrate, e.g. Imwitor 370 from Hüls), polyglyceryl-3 methylglucose distearate (INCI Polyglyceryl Methyl Glucose Distearate, e.g. Tego Care 450 from Evonik) and / or polyethylene glycol (2000) monostearate (INCI; PEG-40 stearate) can be used.
- O / W emulsifiers glyceryl stearate citrate (CAS 39175-72-9, INCI Glyceryl Stearate Citrate, e.g. Imwitor 370 from Hüls), polyglyceryl-3 methylglucose distearate (INCI Polyglyceryl Methyl Glucose Distearate, e
- the emulsion according to the invention contains potassium cetyl phosphate, sodium cetearyl sulfate, sodium stearyl glutamate, alkali salts of saturated fatty acids of chain length C14-C22, in particular sodium stearate, as an anionic emulsifier.
- the emulsion according to the invention contains one or more polyglyceryl fatty acid esters as nonionic emulsifiers.
- the polyglyceryl fatty acid ester particularly preferred according to the invention is polyglyceryl-10 stearate (INCI polyglyceryl-10 stearate).

Kosmetische O/W-Emulsion mit Skleroglucan und hydrophilen UV-Filtersubstanzen Cosmetic O / W emulsion with scleroglucan and hydrophilic UV filter substances
Die vorliegende Erfindung betrifft eine kosmetische Zubereitung enthaltend Skleroglucan und hydrophile UV-Filtersubstanzen. The present invention relates to a cosmetic preparation containing scleroglucan and hydrophilic UV filter substances.
Der Wunsch, schön und attraktiv auszusehen, ist von Natur aus im Menschen verwurzelt. Auch wenn das Schönheitsideal im Laufe der Zeit Wandlungen erfahren hat, so ist das Stre ben nach einem makellosen Äußeren immer das Ziel der Menschen gewesen. Einen wesent lichen Anteil an einem schönen und attraktiven Äußeren haben dabei der Zustand und das Aussehen der Haut. The desire to look beautiful and attractive is inherently rooted in people. Even if the ideal of beauty has changed in the course of time, striving for a flawless appearance has always been the goal of people. The condition and appearance of the skin play a key role in a beautiful and attractive appearance.
Damit die Haut ihre biologischen Funktionen im vollen Umfang erfüllen kann, bedarf sie der regelmäßigen Reinigung und Pflege. Die Reinigung der Haut dient dabei der Entfernung von Schmutz, Schweiß und Resten abgestorbener Hautpartikel, die einen idealen Nährboden für Krankheitserreger und Parasiten aller Art bilden. Hautpflegeprodukte dienen meist der Be feuchtung und Rückfettung der Haut. Häufig sind ihnen Wirkstoffe zugesetzt, welche die Haut regenerieren und beispielsweise ihre vorzeitige Alterung (z. B. das Entstehen von Fält- chen, Falten) verhindern und vermindern sollen. In order for the skin to be able to fully fulfill its biological functions, it needs regular cleaning and care. The cleaning of the skin serves to remove dirt, sweat and residues of dead skin particles, which form an ideal breeding ground for pathogens and parasites of all kinds. Skin care products are mostly used to moisturize and re-oil the skin. Often, active ingredients are added to them that regenerate the skin and, for example, are intended to prevent and reduce its premature aging (eg the appearance of fine lines and wrinkles).
Hautpflegeprodukte bestehen in der Regel aus Emulsionen. Unter Emulsionen versteht man im Allgemeinen heterogene Systeme, die aus zwei nicht oder nur begrenzt miteinander mischbaren Flüssigkeiten bestehen, die üblicherweise als Phasen bezeichnet werden und bei denen eine der beiden Flüssigkeiten in Form feinster Tröpfchen in der anderen Flüssig keit dispergiert ist. Äußerlich und mit bloßem Auge betrachtet erscheinen Emulsionen homo gen. Skin care products are usually made up of emulsions. Emulsions are generally understood to mean heterogeneous systems which consist of two liquids which are immiscible or only partially miscible with one another, which are usually referred to as phases and in which one of the two liquids is dispersed in the other liquid in the form of very fine droplets. Externally and with the naked eye, emulsions appear homogeneous.
Sind die beiden Flüssigkeiten Wasser und Öl und liegen Öltröpfchen fein verteilt in Wasser vor, so handelt es sich um eine ÖI-in-Wasser-Emulsion (O/W-Emulsion, z. B. Milch). Der Grundcharakter einer O/W-Emulsion ist durch das Wasser geprägt. Bei einer Wasser-in-ÖI- Emulsion (W/O-Emulsion, z. B. Butter) handelt es sich um das umgekehrte Prinzip, wobei der Grundcharakter hier durch das Öl bestimmt wird.
Um Emulsionen über einen längeren Zeitraum stabil zu halten und eine Entmischung der Phasen zu verhindern, werden den Emulsionen sogenannte Emulgatoren zugesetzt. Bei Emulgatoren handelt es sich in der Regel um Moleküle mit einem polaren, hydrophilen Struk turelement und einem unpolaren, lipophilen Strukturelement. Ende der vierziger Jahre wurde ein System entwickelt, das die Auswahl von Emulgatoren erleichtern sollte. Jedem Emulga tor wird ein so genannter HLB-Wert (eine dimensionslose Zahl zwischen 0 und 20) zuge schrieben, der angibt, ob eine bevorzugte Wasser- oder Öllöslichkeit vorliegt. Zahlen unter 8 kennzeichnen öllösliche, hydrophobe Emulgatoren, Zahlen über 8 wasserlösliche, hydrophi le. If the two liquids are water and oil and if oil droplets are finely distributed in water, then it is an oil-in-water emulsion (O / W emulsion, e.g. milk). The basic character of an O / W emulsion is shaped by the water. In the case of a water-in-oil emulsion (W / O emulsion, e.g. butter), the principle is reversed, the basic character being determined here by the oil. In order to keep emulsions stable over a longer period of time and to prevent the phases from separating, so-called emulsifiers are added to the emulsions. Emulsifiers are usually molecules with a polar, hydrophilic structural element and a non-polar, lipophilic structural element. At the end of the 1940s a system was developed to make the selection of emulsifiers easier. A so-called HLB value (a dimensionless number between 0 and 20) is assigned to each emulsifier, which indicates whether the water or oil solubility is preferred. Numbers under 8 indicate oil-soluble, hydrophobic emulsifiers, numbers over 8 indicate water-soluble, hydrophilic emulsifiers.
Bei der Herstellung einer Emulsion wird die Wasserphase mit der Lipidphase (Ölphase) unter Rühren vereinigt, wobei die Tröpfchen der inneren Phase der Emulsion auf eine Größe von unter 10 pm zerkleinert werden müssen, damit die Emulsion stabil wird. In the production of an emulsion, the water phase is combined with the lipid phase (oil phase) with stirring, the droplets of the inner phase of the emulsion having to be broken down to a size of less than 10 μm so that the emulsion becomes stable.
Der Trend weg von der vornehmen Blässe hin zur„gesunden, sportlich braunen Haut“ ist seit Jahren ungebrochen. Um diese zu erzielen setzen die Menschen ihre Haut der Sonnenstrah lung aus, da diese eine Pigmentbildung im Sinne einer Melaninbildung hervorruft. Die ultra violette Strahlung des Sonnenlichtes hat jedoch auch eine schädigende Wirkung auf die Haut. Neben der akuten Schädigung (Sonnenbrand) treten Langzeitschäden wie ein erhöh tes Risiko an Hautkrebs zu erkranken bei übermäßiger Bestrahlung mit Licht aus dem UVB- Bereich (Wellenlänge: 280-320 nm) auf. Die übermäßige Einwirkung der UVB- und UVA- Strahlung (Wellenlänge: 320-400 nm) führt darüber hinaus zu einer Schwächung der elasti schen und kollagenen Fasern des Bindegewebes. Dies führt zu zahlreichen phototoxischen und photoallergischen Reaktionen und hat eine vorzeitige Hautalterung zur Folge. The trend away from elegant paleness towards "healthy, sporty brown skin" has been unbroken for years. To achieve this, people expose their skin to solar radiation, as this causes pigment formation in the sense of melanin. However, the ultra violet radiation of sunlight also has a damaging effect on the skin. In addition to acute damage (sunburn), long-term damage such as an increased risk of developing skin cancer occurs when exposed to excessive exposure to light from the UVB range (wavelength: 280-320 nm). The excessive exposure to UVB and UVA radiation (wavelength: 320-400 nm) also leads to a weakening of the elastic and collagen fibers of the connective tissue. This leads to numerous phototoxic and photoallergic reactions and leads to premature skin aging.
Zum Schutz der Haut wurde daher eine Reihe von Lichtschutzfiltersubstanzen entwickelt, die in kosmetischen Zubereitungen eingesetzt werden können. Diese UVA- und UVB-Filter sind in den meisten Industrieländern in Form von Positivlisten wie der Anlage 7 der Kosmetikver ordnung zusammengefasst. To protect the skin, a number of light protection filter substances have therefore been developed that can be used in cosmetic preparations. These UVA and UVB filters are summarized in most industrialized countries in the form of positive lists such as Annex 7 of the Cosmetics Ordinance.
Der Einsatz von hydrophilen UV-Filtern in Emulsionen führt häufig zu einer Destabilisierung dieser Systeme und einer daraus resultierenden Trennung der Phasen. Eine Langzeitstabi- liserung von O/W Emulsionen mit UV-Filtern auch bei erhöhter Temperatur ist daher wün schenswert.
Überraschend gelöst wird die Aufgabe durch kosmetische ÖI-in-Wasser-Emulsionen (O/W- Emulsionen) enthaltend neben einer Wasserphase eine oder mehrere darin dispergierte Öl phasen sowie The use of hydrophilic UV filters in emulsions often leads to a destabilization of these systems and a resulting separation of the phases. Long-term stabilization of O / W emulsions with UV filters, even at elevated temperatures, is therefore desirable. The object is surprisingly achieved by cosmetic oil-in-water emulsions (O / W emulsions) containing, in addition to a water phase, one or more oil phases dispersed therein as well
a) Skleroglucan a) scleroglucan
und and
b) eine oder mehrere hydrophile UV-Filtersubstanzen. b) one or more hydrophilic UV filter substances.
Skleroglucan wird von Pilzarten der Gattung Sclerotium (Basidiomycota, Agariomycetes) als mikrobielles Exopolysaccharid in das umgebende Medium abgegeben. Sclerotium delphinii beispielsweise ist ein bedeutender Pflanzenschädling. Skleroglucan wird auch als Scleroti umgummi (INCI: Sclerotium Gum) bezeichnet. Scleroglucan is released into the surrounding medium as a microbial exopolysaccharide by fungal species of the genus Sclerotium (Basidiomycota, Agariomycetes). Sclerotium delphinii, for example, is a major pest of plants. Scleroglucan is also known as Sclerotium Gum (INCI: Sclerotium Gum).
Skleroglucan ist ein (1— >3; 1— >6)-ß-D-Glucan. Seine mittlere Molmasse beträgt etwa Scleroglucan is a (1—> 3; 1—> 6) -β-D-glucan. Its mean molecular weight is about
5,7 *106 g/mol, sein durchschnittlicher Polymerisationsgrad etwa 35.000. 5.7 * 10 6 g / mol, its average degree of polymerization about 35,000.
Die chemische Struktur des Skleroglucans wird wie folgt veranschaulicht: The chemical structure of scleroglucan is illustrated as follows:
Skleroglucan besteht aus einer linearen (1— >3)-ß-D-Glucan-Kette (OdHioOdOQHIOOd)^, an der statistisch jede dritte Glucose-Einheit mit einem einzelnen (1— >6)-ß-D-Glcp-Rest ver zweigt ist. Scleroglucan consists of a linear (1—> 3) -β-D-glucan chain (O d HioO d OQHIOOd) ^, on which statistically every third glucose unit with a single (1—> 6) -β-D- Glcp residue is branched.
Skleroglucan ist in Wasser gut löslich und kann als Verdicker eingesetzt werden. Der Einsatz von Skleroglucan in kosmetischen Emulsionen ist dem Fachmann an sich bekannt, doch konnte der Stand der Technik nicht den Weg zur vorliegenden Erfindung weisen.
Beispielsweise offenbart die DE 10 2014 015 554 die die Verwendung von Skleroglucan in UV-Filter enthaltenden kosmetischen Zubereitungen, zur Reduzierung der durch die UV- Filter in der Zubereitung hervorgerufenen Verunreinigung und/oder Verfärbung von Textilien. Scleroglucan is readily soluble in water and can be used as a thickener. The use of scleroglucan in cosmetic emulsions is known per se to the person skilled in the art, but the prior art could not point the way to the present invention. For example, DE 10 2014 015 554 discloses the use of scleroglucan in UV filters containing cosmetic preparations to reduce the contamination and / or discoloration of textiles caused by the UV filters in the preparation.
