Description
Zahnreinigungsmittel Zahnpasten und Zahnpulver enthalten als mechanische Reinigungsmittel bzw. Füllstoffe meistens gepulverte Mineralstoffe oder Salze, wie Schlämmkreide, Calciumphosphat, Gips, Kieselsäure usw. Diese Stoffe haben den Nachteil, daß sie, teils wegen ihrer Härte, teils weil sie auch in feinst gepulvertem Zustand Kristallbruchstücke enthalten, den Zahnschmelz abnutzen.Dentifrices contain toothpastes and tooth powders as mechanical Cleaning agents or fillers mostly powdered minerals or salts, such as Chalk, calcium phosphate, gypsum, silica, etc. These substances have the disadvantage that they, partly because of their hardness, partly because they are also in the finest powdered condition Contain crystal fragments that wear out tooth enamel.
Es wurdegefunden, daß Kunstharzeund/oder die bei ihrer Herstellung anfallenden festen Zwischenprodukte in Pulverform sich ausgezeichnet als Zusätze für Zahnreinigungsmittel eignen. Nach ihrer Härte und infolge des Fehlens jeder Kristallecken oder -kanten sind sie als schonende und doch wirksame mechanische Reinigungsmittel in Zahnpasten und Zahnpulvern zu betrachten.It has been found that synthetic resins and / or those used in their manufacture Solid intermediate products in powder form are excellent as additives suitable for tooth cleaning products. According to their severity and as a result of the lack of everyone Crystal corners or edges are considered to be gentle yet effective mechanical ones Consider detergents in toothpastes and toothpowders.
Als brauchbare Kunstharze haben sich z. B. solche erwiesen, die durch Kondensation von Aldehyden, insbesondere Formaldehyd, und Phenolen bzw. Harnstoff, Thioharnstoff, Cyanamid, Dicyanamid, Guanidinoder aromatischen Aminen, oder von Aldehyden unter sich, die unter dem Einfluß von Alkali vor sich geht, oder von Aldehyden mit Naphthalin in Gegenwart von Schwefelsäure oder von mehrwertigen Alkoholen und aromatischen Carbonsäuren, beispielsweise des Phthalsäure=Glycerin-Typs, erhalten werden. Ferner kommen in Frage Polyvinylverbindungen, z. B. Mischpolymerisate aus Vinylchlorid einerseits und Vinyl-bzw. Akrylester andererseits oder Polystyrolprodukte. Auch gehärtete Caseinprodukte haben sich als geeignet erwiesen.As usable synthetic resins have z. B. those proven by Condensation of aldehydes, especially formaldehyde, and phenols or urea, Thiourea, cyanamide, dicyanamide, guanidine or aromatic amines, or of Aldehydes among themselves, which goes on under the influence of alkali, or of aldehydes with naphthalene in the presence of sulfuric acid or polyhydric alcohols and aromatic carboxylic acids, for example of the phthalic acid = glycerol type, obtained will. Polyvinyl compounds such. B. copolymers from Vinyl chloride on the one hand and vinyl or. Acrylic esters, on the other hand, or polystyrene products. Hardened casein products have also proven to be suitable.
An Stelle der fertigen Kunstharze kann man auch die bei ihrer Herstellung anfallenden Zwischenprodukte, sofern sie fest sind, verwenden. Es kommen beispielsweise in Frage Zwischenerzeugnisse, die beim Herstellen von Formaldehyd - Phenolkondensationsprodukten anfallen und unter dem Namen Resite bekannt sind.Instead of the finished synthetic resins, one can also use those used during their manufacture Use any intermediate products, provided they are solid. For example, there are in question intermediate products used in the manufacture of formaldehyde - phenol condensation products occur and are known under the name Resite.
Als besonders geeignet haben sich Kunstharze, die durch Kondensation von Formaldehydharnstoff gewonnen werden, bzw. die bei dieser Kondensation anfallenden festen Zwischenerzeugnisse erwiesen.Synthetic resins, which are produced by condensation, have proven to be particularly suitable are obtained from formaldehyde urea, or those resulting from this condensation solid intermediate products.
Die Kunststoffe können in Form von Preßpulvern zur Anwendung kommen, oder man kann z. B. die fertigen Erzeugnisse bzw. die Verarbeitungsabfälle zu Pulver vermahlen. Die Erzeugnisse werden zweckmäßig in feinst gemahlenem und gesiebtem Zustand den Zahnpasten bzw. -pulvern zugesetzt, die die sonstigen aus kosmetischen oder hygienischen Gründen, erforderlichen Bestandteile enthalten.The plastics can be used in the form of pressed powders, or you can z. B. the finished products or the processing waste into powder grind. The products are suitably finely ground and sieved Condition added to toothpastes or powders, the rest of the cosmetic or hygienic Reasons, contain necessary components.
Die Zusätze können in verschiedenen Mengenverhältnissen je nach_ den Anfordqrungen, die an das Zahnreinigungsmittel. stellt werden, zugesetzt werden. So hat s@ z. B. eine Zahnpasta, die 4o bis 5o % eine§ Harnstoff - Formaldehydkondensationserzeugnisses enthält, gut bewährt.The additives can be used in various proportions depending on the requirements placed on the dentifrice. are added. So s @ z. B. a toothpaste that contains 4o to 5o % a § urea - formaldehyde condensation product, has proven to be good.
Die Zahnpasten nach der Erfindung können noch Zusätze, die z. B. aus medizinischhygienischen oder kosmetischen Gründen erwünscht sind, enthalten. Als solche Stoffe kommen beispielsweise Desinfektionsmittel, wie Gemische hochmolekularer Alkyldimethylbenzylammoniumchloride, zahnsteinlösende Mittel, wie phenolsulfosaure Alkalisalze, oder geschmacks- und geruchsverbessernde Substanzen, wie Pfefferminzöl, in Frage.The toothpastes according to the invention can also contain additives that, for. B. off are desirable for medical, hygienic or cosmetic reasons. as such substances come, for example, disinfectants, such as mixtures of high molecular weight Alkyldimethylbenzylammonium chlorides, anti-tartar agents such as phenol sulfonic acid Alkali salts, or substances that improve taste and smell, such as peppermint oil, in question.
Als Zahnpasten nach der Erfindung kommen z. B. die folgenden in Betracht:
