Description
Verfahren zur Herstellung eines Adsorbatgels von Tonerdehydrat und Pektin, insbesondere für kosmetische und pharmazeutische Zwecke Die Wirkung der besten Emulgatoren beruht bekanntlich auf der Bildung von zusammenhängenden Häutchen um den dispersen Anteil.Process for the production of an adsorbate gel from alumina hydrate and Pectin, especially for cosmetic and pharmaceutical purposes The effect of the It is well known that the best emulsifiers are based on the formation of coherent skins around the disperse fraction.
So wird beispielsweise die beständige Verteilung des Butterfettes in der Milch von solchen Eiweißhäutchen bedingt. Stoffe, von denen bekannt ist, daß sie die Bildung von Emulsionen vermitteln, sind: Gummiarabikum, Pektin, Tragant, Gelatine, Agar, Leim, Hämoglobin, Eieralbumin, Lecithin, Alkalisalze der höheren Fettsäuren, Natriumsalze bocbmolekularer Sulfosäuren, Saponin, unlösliche, feinst verteilte feste Körper, wie Ton, Tonerdehydratgel, Kieselgur, Zinkstaub und Bleiglätte.This is how, for example, the constant distribution of the butterfat due to such protein membranes in milk. Substances known to that they mediate the formation of emulsions are: gum arabic, pectin, tragacanth, Gelatin, agar, glue, hemoglobin, egg albumin, lecithin, alkali salts of the higher Fatty acids, sodium salts of molecular sulfonic acids, saponin, insoluble, finest dispersed solids such as clay, alumina hydrate gel, diatomaceous earth, zinc dust and black lead.
Mit den bisher bekanntgewordenen Emulsionen war es nur schwer möglich, Arbeitsprozesse in Anwesenheit von mehrwertigen Metallsalzen durchzuführen, weil die Emulsionen gegen die genannten Verbindungen nicht beständig genug waren. Ein neueres Verfahren (Patentschrift 607 609, K1. 23 c) behebt diesen Nachteil dadurch, daß 3 es zur Herstellung hierfür geeigneter Emulsionen Pflanzenphosphatidc unter Zusatz von Eigelb als Stabilisator verwendet. Auf solche Weise hergestellte Stoffe haben jedoch den Mangel, daß sie nur in konzentrierter Form oder in Lösung, wenn sie mit Fetten verbunden sind, eine gute Haltbarkeit aufweisen ;-andernfalls zersetzen sie sich leicht, und ihre Emulgierfähigkeit läßt nach.'Von den wegen ihrer Unschädlichkeit insbesondere für kosmetische und pharmazeutische Zwecke bevorzugten eiweiß- und kohlehydrathaltigen Stabilisatoren und Emulgatoren ist bekannt, daß dieselben namentlich in Emulsionen sehr leicht zersetzlich sind und dadurch die Emulsionen zerstören, wobei diese Zerstörung infolge der notwendigen größeren Mengen an Stabilisator bzw. Emulgator noch beschleunigt wird. With the previously known emulsions it was difficult to Carry out work processes in the presence of polyvalent metal salts because the emulsions were not resistant enough to the compounds mentioned. A more recent method (patent specification 607 609, K1. 23 c) eliminates this disadvantage by that 3 it for the production of emulsions suitable for this purpose plant phosphatide Added egg yolk used as a stabilizer. Fabrics made in this way however, have the shortcoming that they are only available in concentrated form or in solution, though they are associated with fats, have a good shelf life; otherwise they decompose it is easy to emulsify, and because of its harmlessness Protein and protein preferred especially for cosmetic and pharmaceutical purposes Carbohydrate-containing stabilizers and emulsifiers are known to have the same name are very easily decomposable in emulsions and therefore the emulsions destroy, this destruction as a result of the necessary larger amounts of stabilizer or Emulsifier is accelerated.
Es wurde nun gefunden, daß man ein beständiges, hervorragend emulsionsstabilisierend'4 wirksames Mittel herstellen kann, wenn man aus wässerigen Lösungen von Aluminiumsalz und Pektin in geeigneten Konzentrationen mittels Ammoniakflüssigkeit ein Adsorbat von Tonerdehvdrat und Pektin herstellt. Pektin als oberflächenaktiver Stoff bedingt, daß das Adsorbat in höchst disperser Form anfällt, überdies trägt es wesentlich zur Herabsetzung der Grenzflächenspannung zwischen den beiden nicht mischbaren Flüssigkeiten der Emulsionen bei und gewährleistet dadurch in den letzteren höhere Konzentrationen an disperser Phase. It has now been found that a stable, excellent emulsion stabilizing'4 Effective means can be produced if one can make from aqueous solutions of aluminum salt and pectin in suitable concentrations using ammonia liquid an adsorbate of alumina and pectin. Pectin as a surface-active substance, that the adsorbate is obtained in a highly dispersed form, moreover, it contributes significantly to reduce the interfacial tension between the two immiscible liquids of the emulsions and thus ensures higher concentrations in the latter of disperse phase.
Erfindungsgemäß hergestelltes Aluminiumhydroxydpektinadsorbat vermag nicht nur mit Fetten und Ölen Emulsionen zu bilden, sondern auch mit unverseifbaren Kohlenwasserstoffen. Da es bekannt ist, daß alle Stoffe, die Eiette emulgieren, wie z. B. Gallcnflüssigkeit, harzsaures Natron, Saponin, schwach auch Soda, Wasserglas und fetter Ton, seifenartig wirken, sind alle Voraussetzungen für eine Verwendung auch des Tonerdehydratpcktingels als Wasch- und Reinigungsmittel gegeben. So zeigte es sich denn auch, daß Verunreinigungen verschiedenster Art, beispielsweise Ruß, sowohl von Textilgeweben und Gebrauchsgegenständen wie auch von der Haut durch das eIfindungsgemäß hergestellte Mittel leicht entfernt werden können. Aluminum hydroxide pectin adsorbate produced according to the invention is capable of To form emulsions not only with fats and oils, but also with unsaponifiable ones Hydrocarbons. Since it is known that all substances that emulsify Eiette, such as B. Bile, soda resin, saponin, weakly also soda, water glass and fat clay, appearing soap-like, are all prerequisites for use Also given the alumina hydrate putty gel as a detergent and cleaning agent. So showed it is also the case that impurities of various kinds, for example soot, of textile fabrics and everyday objects as well as of the skin through the A means produced according to the invention can be easily removed.
Paraffinöl kann vermittels des Adsorbats emulgiert und die Emulsion z. B. in der Textilindustrie als Schmälzmittel von guter Gleitwirkung, das auf der Faser nicht oxydiert, verwandt werden (vgl. allgemeine Öl- und Fettzeitung 36. Jahrgang, 1939, S. 206). Paraffin oil can be emulsified by means of the adsorbate and the emulsion z. B. in the textile industry as a lubricant of good lubricity that is based on the Fiber not oxidized, be used (see general oil and fat newspaper 36th year, 1939, p. 206).
Ebenso wie reine Tonerdegallerte kann auch das Adsorbat als Grundlage für Zahnpasten und Hautkreme dienen. Zusammen mit Glycerin gibt es eine zweckmäßige alkalifreie Grundlage fiir Salben und Pasten für kosmetischen und arzneilichen Gebrauch. Hautkreme mit Adsorbatgallerten, die schwach sauer sind. schen wie weiße Vaseline aus und dönnen vorteilbaft zu völlig fettfreien Krems, wo auch Vaselin, Paraffin, Stearin u. ä. unerwünscht sind, verarbeitet werden. Zu fetthaltigen Salbengrundlagen und sogenannten Salbenseifen lassen sich die erfindungsgemäß hergestellten Adsorbatgele mit Fetten und Ölen, beispielsweise Wollfett, selbstverständlich ebenfalls verarbeiten. Just like pure clay jelly, the adsorbate can also be used as a basis serve for toothpastes and skin cream. Along with glycerin, there is an expedient one Alkaline-free base for ointments and pastes for cosmetic and medicinal use. Skin cream with adsorbate jelly that is slightly acidic. like white petroleum jelly and can be used to make completely fat-free creams, where also vaseline, paraffin, Stearin and the like are undesirable. To fatty ointment bases and so-called ointment soaps, the adsorbate gels prepared according to the invention can be used Process with fats and oils, for example wool fat, of course.
A u s f ü h r u n g s b e i s p i e l 50 g Aluminiumsulfat werden in 31 asser gelöst. Nach vollkommener Lösung desselben werden 200 ccm 5%iger Pektinextrakt gut eingerührt, worauf die Fällung des Adsorbatgels durch Zusatz von joccm 14%igen Ammoniakwassers vorgenommen wird. Das ausgefallene Aluminiumhydroxydpektinadsorbat setzt sich innerhalb weniger Minuten gut ab und wird mittels Büchnertrichter abgesangt und mit Wasser nachgewaschen, bis das Waschwasser pektinfrei ist. Auf diese Weise werden 380 g eines salbenartigen, schwach gelblich gefärbten tonerdehydratgelpektinadsolbats von etwa 95% Wassergehalt erhalten. Die Trockensubstanz des Adsorbats besteht zu annäbernd gleichen Teilen aus Aluminiumh ydroxyd und Pektin. D o u s t o u t p i o rt 50 g of aluminum sulphate solved in 31 water. When it is completely dissolved, 200 cc of 5% pectin extract are obtained well stirred in, whereupon the adsorbate gel is precipitated by adding 14% strength Ammonia water is made. The precipitated aluminum hydroxide pectin adsorbate settles well within a few minutes and is singed using a Büchner funnel and washed with water until the washing water is pectin-free. In this way 380 g of an ointment-like, pale yellowish alumina hydrate gel pectin adsolbate obtained from about 95% water content. The dry substance of the adsorbate is too Approximately equal parts of aluminum hydroxide and pectin.
