Description

Verfahren zur Verbesserung von Pudergrundlagen geringerer Feinheit und Deckkraft Bekanntlich verwendet man als Grundlage für Puder die Zink-, Strontium- und Aluminiumsalze höherer Fettsäuren, wie z. B. Stearinsäure, Undekansäure, ferner die in den Patentschriften 626 147 und 642 344 beschriebenen fettsauren Salze. Sie besitzen eine gute Deckkraft, starkes Haftvermögen und gute Verreibbarkeit. Als Streckmittel für diese hochwertigen Stoffe dienen seit langem das Talkum und ähnliche Erden; diese weisen jedoch die guten Eigenschaften der erwähnten fettsauren Salze, abgesehen von der Verreibbarkeit, nur in untergeordnetem Maße auf.Process for improving powder bases of lower fineness and opacity It is known that the zinc, strontium and aluminum salts of higher fatty acids, such as. B. stearic acid, undecanoic acid, and also the fatty acid salts described in patents 626 147 and 642 344. They have good covering power, strong adhesion and good friability. Talc and similar earths have long been used as extenders for these high-quality substances; However, these have the good properties of the fatty acid salts mentioned, apart from the friability, only to a minor extent.

Man vermag nun Talkum, Kaolin, Chinaclay usw. die hervorragenden Eigenschaften der obergenannten fettsauren Salze zu verleihen, wenn man sie mit Lösungen vön Zinksalzen höherer Fettsäuren behandelt. Man suspendiert beispielsweise das Talkum in wäßrigen Lösungen von Alkaliseifen und schlägt durch Zugabe löslicher Zinksalze, wie Chlorzink, die unlösliche Metallseife auf dem Talkum nieder. Man erhält jedoch bessere Pudergrundlagen, wenn man Zinkstearat oder Zinkundekanat in geeigneten organischen Lösungsmitteln, wie Tetrachlorkohlenstoff, Xylol, Chlorbenzol u. dgl., gegebenenfalls bei erhöhter Temperatur, auf Talkum einwirken läßt.Talc, kaolin, quinaclay, etc. can now have excellent properties of the fatty acid salts mentioned above, if they are mixed with solutions of zinc salts higher fatty acids treated. For example, the talc is suspended in aqueous Solutions of alkali soaps and proposes by adding soluble zinc salts, such as zinc chloride, the insoluble metal soap settled on the talc. However, you get better powder bases, if you use zinc stearate or zinc undecanate in suitable organic solvents, such as carbon tetrachloride, xylene, chlorobenzene and the like Temperature to act on talc.

Das so behandelte Talkum besitzt eine verbesserte Deckkraft, ein hervorragendes Haftvermögen und ist einer mechanisch hergestellten Mischung von Talkum mit z. B. Zinkstearat weit überlegen.The talc treated in this way has an improved covering power, an excellent one Adhesion and is a mechanically produced mixture of talc with z. B. Far superior to zinc stearate.

Man hat bereits Talkum und andere Erden mit Stoffen, wie Schwefel, Borsäure, und ähnlichen arzneilichen Körpern behandelt, um sie der Haut in möglichst feiner Verteilung darbieten zu können. Durch diese Maßnahme wurde aber die Verreibbarkeit und Deckkraft der als Grundlagen dienenden Körper nicht` verbessert.You already have talc and other earths with substances such as sulfur, Boric acid, and similar medicinal bodies treated to she the To be able to present skin in the finest possible distribution. Through this measure was but the friability and opacity of the bodies that serve as the basis are not improved.

Beispiel i In eine Lösung von 2o Teilen Zinkstearat in ioo Teilen N.ylol trägt man bei i2o° iooTeile Talkum ein, läßt unter Rühren erhalten, saugt ab und trocknet.Example i In a solution of 20 parts of zinc stearate in 100 parts Nylol is added to talc at 130 °, left to obtain with stirring, and sucked off and dry.

Zur Herstellung eines hochwertigen Puders mischt man Talkum nach Beispiel i ...... 7o Teile, Titandioxyd ............... 3 - , Zinkoxyd ................. 2o - , Calciumcarbonat ........... 2 - , Magnesiumcarbonat ......... 5 - Beispiel 2 i oo Teile Talkum werden in einer Lösung von 2o Teilen undekansaurem Natrium und 0,5 Teilen einer Verbindung gemäß Patent 5464o6 gut verrührt. Dann läßt man bei 9o° 6,6 Teile Chlorzink in i 5o Teilen Wasser langsam zulaufen, rührt kurz nach, saugt ab, wäscht und trocknet.Mixing is used to make a high quality powder Talc according to example i ...... 7o parts, Titanium dioxide ............... 3 -, Zinc oxide ................. 2o -, Calcium carbonate ........... 2 -, Magnesium carbonate ......... 5 - EXAMPLE 2 100 parts of talc are stirred well in a solution of 20 parts of undecanoate sodium and 0.5 part of a compound according to patent 5464o6. Then 6.6 parts of zinc chloride in 150 parts of water are slowly run in at 90 °, the mixture is stirred briefly, filtered off with suction, washed and dried.
