Description

Eine Beschreibung solcher Mikrohohlperlen findet sich in der USA.-Patentschrift 36 15 972 und in der Zeitschrift »Modern Plastics« 1969, August, S. 55. A description of such hollow microbeads can be found in the USA patent 36 15 972 and in the magazine "Modern Plastics" 1969, August, p. 55.

Zum Verbinden, bzw. zum Einbetten der Mikro- For connecting or embedding the micro-

hohlperlen eignen sich alle bekannten sogenannten »Salbengrundlagen«, insbesondere pflanzliche und tierische Fette und Öle, Stearin, Wollfett, Fettalkohole, Lanolin, Wachse, mineralische Öle, Vaseline, Gelatine, Glyzerin, niedrige Alkohole, Lösungsmittel usw.all known so-called "ointment bases" are suitable for hollow pearls, in particular vegetable and animal fats and oils, stearin, wool fat, fatty alcohols, Lanolin, waxes, mineral oils, petroleum jelly, gelatin, glycerine, low alcohols, Solvents etc.

Erfindungsgemäß besteht die Creme od. dgl, volumenmäßig zu 5 bis 96%, vorzugsweise zu 18 bis 720/0, aus Mikrohohlperlen. According to the invention, the cream or the like consists of 5 to 96%, preferably 18 to 720/0, from hollow microbeads.

Die erfindungsgemäße Creme od. dgl. hat eine Dichte von 0,05 bis 0,91, vorzugsweise von 0,16 bis 0,48, und besitzt eine schaumartige Konsistenz. The cream or the like according to the invention has a density of 0.05 to 0.91, preferably from 0.16 to 0.48, and has a foam-like consistency.

Sie läßt sich bei allen Temperaturen besonders leicht auf die Haut auftragen und gleichmäßig auf ihr verteilen. It is particularly easy to apply to the skin at all temperatures apply and distribute evenly on it.

Die schaumartige Konsistenz der erfindungsgemäßen Creme wird durch Druck, Wärme, bewegte Luft, sowie durch bewegtes Wasser nicht zerstört. The foam-like consistency of the cream according to the invention is through Pressure, heat, moving air and moving water are not destroyed.

Die Creme od. dgl. ist atmungsaktiv und stört in Schichten unter 1 mm die Hautatmung nicht oder kaum. Sie ist deshalb mit entsprechenden Wirksubstanzen als Creme für Gesichtsmasken und als Salbe bei Brandverletzungen besonders gut geeignet. The cream or the like is breathable and interferes in layers 1 mm the skin respiration hardly or not at all. It is therefore with appropriate active ingredients Particularly suitable as a cream for face masks and as an ointment for burn injuries.

In Folge der in den Mikrohohlperlen eingekapselten Luft, die auch unter Druck nicht entweichen kann, besitzt die erfindungsgemäße Creme ausgezeichnete kälte- und wärmeisolierende Eigenschaften. Sie ist deshalb als Schutzcreme gegen kaltes Wasser, wie sie von Schwimmern und Tauchern verwendet wird, besonders geeignet. As a result of the air encapsulated in the hollow microbeads, that too cannot escape under pressure, the cream of the present invention is excellent cold and heat insulating properties. It is therefore used as a protective cream against cold water, such as that used by swimmers and divers, is particularly suitable.

Die vorzugsweise verwendeten hochpolymeren Mikrohohlperlen aus Polyvinylidenchlorid-Copolymerisat sind unbrennbar. In Verbindung mit unbrennbaren flüssigen oder pastösen Substanzen, wie z. B. Chlorparaffin, sind sie besonders geeignet als Schutzcreme bei Brandkatastrophen, bei Arbeiten an Hochöfen usw. The preferably used high polymer hollow microbeads made of polyvinylidene chloride copolymer are incombustible. In connection with non-flammable liquid or pasty substances, such as B. chlorinated paraffin, they are particularly suitable as a protective cream for fire disasters, when working on blast furnaces etc.

Ein weiterer Vorteil der Erfindung besteht darin, daß sich die Mikrohohlperlen als solche physiologisch absolut unbedenklich gegenüber dem menschlichen bzw. tierischen Körper und den Wirksubstanzen verhalten. Another advantage of the invention is that the hollow microbeads as such physiologically absolutely harmless compared to the human or animal The body and the active substances.

Claim: cream, ointment, paste with medical and / or cosmetic Active substances, with cleaning and / or protective properties, d a -characterized by, that the cream is liquid, pasty or wax-like, and at least partially off Micro-hollow beads, whose thin shell is made of a thermoplastic material is formed, and that these microballoons have different diameters. Die Erfindung betrifft eine Creme mit niedriger Dichte, insbesondere eine Creme, Salbe, Paste od. dgl. The invention relates to a low density cream, in particular a cream, ointment, paste or the like. mit medizinischen und/oder kosmetischen Wirksubstanzen, bzw. reinigenden und/oder schützenden Eigenschaften.with medicinal and / or cosmetic active substances or cleaning agents and / or protective properties. Eine Creme od. dgl., wie sie beispielsweise zum Reinigen und Pflegen von Zähnen und Zahnfleisch, sowie zum Schützen der Haut und zum Heilen von Wunden, sowie zum Behandeln von Allergien, ferner als Gesichtsmasken, zum Entfernen von Körperhaaren und Hornhaut, sowie zum Rasieren benutzt wird, ist in der Regel eine bei Zimmertemperatur flüssige bis halbfeste oder pastöse tixotrope Substanz mit einer hohen Dichte. Physikalisch gesehen sind es Dispersionen, Emulsionen, Pasten, Öle, Gele, Lösungen oder Mischungen der genannten. Meistens enthalten sie für die jeweiligen Anwendungsgebiete neben anderem medizinische und/oder kosmetische Wirksubstanzen. A cream or the like, such as those used, for example, for cleaning and care teeth and gums, as well as protecting the skin and healing wounds, as well as for treating allergies, also as face masks, for removing Body hair and calluses, as well as being used for shaving, is usually one at room temperature liquid to semi-solid or pasty thixotropic substance with a high density. From a physical point of view, these are dispersions, emulsions, pastes, Oils, gels, solutions or mixtures of the above. Mostly they contain for that respective areas of application alongside other medicinal and / or cosmetic active substances. Es ist bekannt eine Creme od. dgl. zu Schäumen. It is known to foam a cream or the like. Dazu verwendet man ein Treibmittel, daß durch seine Expansion (Verdampfung) die Creme beim Verlassen des Druckbehälters aufschäumt.To do this, a propellant is used that, through its expansion (evaporation) the cream foams when it leaves the pressure vessel. Es ist auch bekannt eine Creme od. dgl. zusammen mit Emulgatoren und Schaumstabilisatoren mechanisrh mittels eines Schnellrührers zu Schäumen. It is also known a cream or the like together with emulsifiers and foam stabilizers to foam mechanically using a high-speed stirrer. Ferner ist es bekannt eine Creme od. dgl. direkt auf der Haut zu Schäumen (Rasierschaum). It is also known to apply a cream or the like directly to the skin Foaming (shaving foam). In allen Fällen ist die geschäumte Creme od. dgl. In all cases, the foamed cream or the like. äußerst instabil und sensibel. Der Schaum kollabiert nach kurzer Zeit durch Feuchtigkeitsabgabe an die Haut und/oder die Atmosphäre oder spontan bei Druck. Besonders instabil ist der Schaum bei Wärme und bewegter Luft und bei bewegtem Wasser. Der von einer geschäumten Creme od. dgl. erwünschte isolierende, schützende, heilende, eine Wirksubstanz speichernde Effekt wird daher nur unvollkommen erreicht. Außerdem ist die Creme, insbesondere wenn sie in stärkerer Schicht aufgetragen wird, nicht atmungsaktiv und verhindert die Hautatmung.extremely unstable and sensitive. The foam collapses after a short time by the release of moisture to the skin and / or the atmosphere or spontaneously under pressure. The foam is particularly unstable in warmth and moving air and in moving water. The insulating, protective, healing, and healing properties desired by a foamed cream or the like. an effect that stores the active substance is therefore only incompletely achieved. aside from that the cream is not, especially if it is applied in a thick layer breathable and prevents skin breathing. Ein weiterer Nachteil besteht darin, daß die zur Schaumerzeugung notwendigen, in eine Creme od. dgl. eingebauten, meist niedermolekularen Substanzen, wie z. B. das Treibmittel, die Emulgatoren und die Schaumstabilisatoren mit vielen medizinischen und/oder kosmetischen Wirksubstanzen unverträglich sind, bzw. mit ihnen reagieren und ihre Wirkung vermindern oder unerwünscht steigern. Another disadvantage is that the foam generation Necessary, mostly low-molecular substances built into a cream or the like, such as B. the blowing agent, the emulsifiers and the foam stabilizers with many medical and / or cosmetic active ingredients are incompatible with or with react to them and reduce or undesirably increase their effect. Ein Nachteil besteht auch darin, daß insbesondere Treibmittel und Emulgatoren physiologisch nicht indifferent sind und besonders unangenehm auf die Schleimhäute wirken und oft Allergien verursachen. A disadvantage is also that in particular propellants and Emulsifiers are physiologically not indifferent and particularly unpleasant on the Mucous membranes work and often cause allergies. Ein wesentlicher Nachteil jeder Creme od. dgl. besteht darin, daß ihre Viskosität in hohem Maße von der Temperatur der Creme, der Luft und der des Körpers abhängt, was eine gleichmäßige Verteilung erschwert bzw. unmöglich macht. A major disadvantage of any cream or the like. Is that their viscosity depends to a large extent on the temperature of the cream, the air and that of the des Body, which makes an even distribution difficult or impossible. Die Viskositäten aller Cremen od. dgl., insbesondere solcher auf fettiger Creme-/Salbengrundlage mit relativ niedriger Dichte, sind im Gebrauchsbereich von - 250 C (UV-Schutzcreme für den Wintersport) bis +550 C (Uv-Schutzcreme für den Badeurlaub) sehr verschieden und liegen zwischen flüssig bis wachsähnlich. The viscosities of all creams or the like, especially those on greasy cream / ointment base with a relatively low density are in the range of use from - 250 C (UV protection cream for winter sports) to +550 C (UV protection cream for the beach holiday) very different and range from liquid to wax-like. Die Erfindung hat sich die Aufgabe gestellt, diese Nachteile zu beheben und eine Creme zu schaffen, die eine niedrige Dichte besitzt und die in einem weiten Temperaturbereich annähernd die ursprüngliche Viskosität beibehält. Die in schaumartiger Konsistenz keine oder kaum Feuchtigkeit an die Atmosphäre abgibt und die in diesem schaumartigen Zustand unter Druck und/oder Wärme nicht kollabiert, sich leicht und gleichmäßig verteilen läßt, isolierende und atmungsaktive Eigenschaften besitzt, physiologisch indifferent ist und sich den Wirksubstanzen gegenüber neutral verhält. Ferner gehört es zur Aufgabe der Erfindung, teure Wirksubstanzen und teure Salbengrundlagen zu sparen. The invention has set itself the task of eliminating these disadvantages and to create a cream which has a low density and which is wide Temperature range approximately maintains the original viscosity. The foam-like Consistency releases little or no moisture into the atmosphere and that in this foam-like state under pressure and / or heat does not collapse, easily and can be distributed evenly, has insulating and breathable properties, is physiologically indifferent and behaves neutrally towards the active substances. It is also part of the object of the invention to provide expensive active ingredients and expensive ointment bases to save. Die Lösung dieser Aufgabe besteht nach der Erfindung in den Merkmalen des Kennzeichen des Anspruchs und lautet: Creme, Salbe, Paste mit medizinischen und/oder kosmetischen Wirksubstanzen, mit reinigenden und/oder schützenden Eigenschaften, dadurch gekennzeichnet, daß die Creme flüssig, pastös oder wachsähnlich ist, und mindestens teilweise aus Mikrohohlperlen besteht, deren dünne Hülle aus einem thermoplastischen Kunststoff gebildet ist, und daß diese Mikrohohlperlen verschiedene Durchmesser besitzen. According to the invention, this object is achieved in the features of the characteristic of the claim and reads: cream, ointment, paste with medicinal and / or cosmetic active ingredients, with cleaning and / or protective properties, characterized in that the cream is liquid, pasty or wax-like, and at least partially consists of hollow microbeads, the thin shell of which is made of a thermoplastic Plastic is formed and that these hollow microbeads have different diameters own. In besonders bevorzugter Weise sind die Mikrohohlperlen von der flüssigen oder pastösen Substanz völlig umgeben, also in sie eingebettet. Gemäß der Erfindung besitzen die Mikrohohlperlen eine glatte Oberfläche und kommen immer in unterschiedlicher Größe, also mit verschiedenen Durchmessern zur Verwendung. In bevorzugter Weise besteht die geschlossene elastische Hülle der Mikrohohlperlen aus Polyvinylidenchlorid-Copolymerisat. In a particularly preferred manner, the hollow microbeads are of the liquid type or pasty substance completely surrounded, so embedded in it. According to the invention The hollow microbeads have a smooth surface and always come in different sizes Size, so with different diameters for use. In a preferred way the closed elastic shell of the hollow microbeads consists of polyvinylidene chloride copolymer. Unter Mikrohohlperlen werden hier auch Mikrohohlkugeln verstanden, deren dünne Hülle aus einem thermoplastischen Kunststoff besteht, und die innen hohl sind, bzw. in ihrem Kern ein Gas enthalten, welches vorzugsweise Luft ist. Die zur Anwendung kommenden Mikrohohlperlen weisen, wie bereits erhähnt, unterschiedliche Durchmesser auf, und zwar von 0,005 bis 0,65 mm, vorzugsweise von 0,01 bis 0,09 mm. Micro-hollow beads are also understood here to mean micro-hollow spheres, whose thin shell consists of a thermoplastic material, and the inside are hollow, or contain a gas in their core, which is preferably air. As already mentioned, the hollow microbeads used are different Diameter, from 0.005 to 0.65 mm, preferably from 0.01 to 0.09 mm.
