Description
Haarwaschmittel. Als Haarwaschmittel kommen heute Mischungen von Natriumbikarbonat und Seifenpulver in erster Linie zur Anwendung. Bei dem Gebrauch der verdünnten, heißen Lösungen ist es nun ein Nachteil, daß man den prozentualen Anteil des Bikarbonats, der in Soda übergeht, nicht quantitativ messen kann. Ferner kann ein Teil des Bikarbonats beim Lagern in feuchter Luft und besonders in Luft, die etwas Säure oder Ammoniak enthält, in Soda übergehen. Wenn nach praktischer oder analytischer Erfahrung die Menge Soda, die entsteht, für gewöhnlich nur gering ist, und 5 bis i o Prozent des Bikarbonats nicht übersteigt und in dieser Menge kaum schädlich wirken kann, so ist es doch vorteilhaft, diese Vorgänge ausschließen zu können und ein völlig beständiges und beständig wirkendes Präparat zu haben.Shampoos. Mixtures of sodium bicarbonate are used as shampoos today and soap powder are primarily used. When using the diluted, In hot solutions, it is a disadvantage that the percentage of bicarbonate which turns into soda, cannot measure quantitatively. It can also contain some of the bicarbonate when storing in humid air and especially in air that has some acid or ammonia contains, turn into soda. If, after practical or analytical experience, the The amount of soda that is produced is usually only a small amount, and 5 to 10 percent of the Bicarbonate does not exceed and in this amount can hardly be harmful, so it is advantageous to be able to exclude these processes and a completely permanent one and to have a permanent preparation.
Es wurde nun gefunden, daß Mischungen von Natriumbikarbonat und trockenem Dinatriumphosphat und Seifenpulver besondere Vorzüge besitzen.It has now been found that mixtures of sodium bicarbonate and dry Disodium phosphate and soap powder have particular benefits.
Es ist bereits aus der Patentschrift i2¢7, Klasse z3, bekannt, daß Mischungen von Seifen mit Dinatriumphospliat einen ausgezeichneten Wascheffekt geben und auch auf die menschliche Haut besonders günstig einwirken.It is already known from patent specification i2 [7, class z3 that Mixtures of soaps with disodium phosphate give an excellent washing effect and also have a particularly beneficial effect on human skin.
Es ist ferner bekannt, daß Kristalle von Dinatriumphosphat aus der Luft Kohlensäure anziehen, wobei sich Mononatriumphosphat und Natriumbikarbonat bilden (H a g e r , Handbuch der pharmazeutischen Praxis i 9 i o, II. S..159; Patentschrift 288523).It is also known that crystals of disodium phosphate from the Air will attract carbonic acid, being monosodium phosphate and sodium bicarbonate form (H a g e r, Handbook of Pharmaceutical Practice i 9 i o, II. S..159; Patent 288523).
Versuche ergaben, daß trockenes Dinatriumphosphat, dem der größere Teil des Kristallwassers entzogen ist, NaHC03 vor dem Übergang in Soda schützt. Es kann dies dadurch erklärt werden, daß zunächst das Phosphat wie ein Trockenmittel wirkt, sobald aber Kohlensäure frei wird, reagiert sie im Sinne obigen Zitates, und es bildet sich etwas Monophosphat und Natriumbikarbona.t und Soda in molekularem Verhältnis, worauf sich Monophosphat und Soda, wieder zu Dinatriumphosphat und Natriumbikarbonat umlagern kann. Außer dem Dinatriumphosphat können auch noch andere geeignete Trockenmittel, z. B. entwässertes Natriumsulfat, beigefügt werden.Tests have shown that dry disodium phosphate, which is the larger Part of the water of crystallization is withdrawn, protecting NaHC03 from being converted into soda. This can be explained by the fact that initially the phosphate acts as a desiccant works, but as soon as carbonic acid is released, it reacts in the sense of the above quote, and it forms some monophosphate and sodium bicarbonate. t and soda in molecular Ratio, whereupon monophosphate and soda, again to disodium phosphate and sodium bicarbonate can rearrange. In addition to disodium phosphate, other suitable drying agents can also be used, z. B. dehydrated sodium sulfate, are added.
Bei Erhitzen der Lösungen von NaHC03 einerseits und von N aHCO3 -@ Na:,HPO, anderseits zeigt sich eine sichtliche Differenz der Kohlensäureabspaltung, die durch den Phosphatzusatz gemindert wird.When heating the solutions of NaHC03 on the one hand and N aHCO3 - @ Na:, HPO, on the other hand there is a noticeable difference in carbon dioxide elimination, which is reduced by the addition of phosphate.
Bei der Verwendung als Haarwaschmittel zeigt sich, daß der Dinatriumphosphatzusatz verhindert, daß die Haare zu trocken werden, und bewirkt, daß sie eine natürliche Glätte behalten, obgleich die Waschwirkung eine vollständige ist.When used as a shampoo, it is found that the disodium phosphate additive prevents hair from becoming too dry and makes it natural Maintain smoothness even though the washing effect is complete.
Worauf dieser Effekt beruht, ist mit Sicherheit nicht zu erklären. Außer obigen Reaktionen kommt auch noch Bildung von kompleten Stoffen, wie Verbindungen von basischem Phosphat und Seife, in Betracht, die . wieder durch Bikarbonat beeinflußt werden.What this effect is based on cannot be explained with certainty. In addition to the above reactions, there is also the formation of complete ones Fabrics, such as compounds of basic phosphate and soap, into consideration that. through again Bicarbonate can be affected.
Als günstiges Verhältnis erscheint ein Gemisch 50 Prozent Natriumbikarbonat, 3o Prozent Seife und =o Prozent Dinatriumphosphat. das noch 5H.,0 als Kristallwasser enthält. A mixture of 50 percent sodium bicarbonate, 3o percent soap and = 0 percent disodium phosphate appears to be a favorable ratio. which still contains 5H., 0 as water of crystallization.
