Description
Zur Herstellung von flüssigen Waschmitteln, die beispielsweise Alkylarylsulf onate, Alkylsulfonate, Alkylsulfate, Fettsäurekondensationsprodukte mit Oxyalkan- und Aminoalkansulfonsäuren bzw. deren stickstoffsubstituierten Derivaten und Aminoalkancarbonsäuren enthalten, verwendet man nicht nur die Alkalisalze von SuIf on- oder Carbonsäuren, sondern auch die Salze von Alkanolamine^ wie z. B. des Mono-, Di- und Triäthanolamins, 1,3-Methoxypropylamins, Morpholine und 1,3-Oxypropylaminlauryläthers, die sich durch verbesserte Löslichkeit und Hautverträglichkeit auszeichnen. Derartige alkanolaminsalzhaltige Waschmittel dunkeln jedoch unter Lichteinwirkung stark nach und färben sich beim Lagern allmählich braun. Es ist bekannt, daß man die Verfärbung von Alkanolaminen durch Behandeln mit gasförmigem Schwefeldioxyd vermindern kann. Wendet man jedoch das Verfahren auf die obengenannten Waschmittel an, so erhält man trübe und Niederschläge enthaltende Lösungen.For the production of liquid detergents, such as alkylarylsulfonates, alkylsulfonates, alkylsulfates, Fatty acid condensation products with oxyalkane and aminoalkane sulfonic acids or their nitrogen-substituted ones Containing derivatives and aminoalkanecarboxylic acids, not only the alkali salts are used of sulfon or carboxylic acids, but also the salts of alkanolamines such as. B. of mono-, di- and triethanolamine, 1,3-methoxypropylamine, morpholines and 1,3-oxypropylamine lauryl ethers, which are characterized by improved solubility and skin tolerance. Such detergents containing alkanolamine salts However, they darken considerably when exposed to light and gradually turn brown during storage. It is known that the discoloration of alkanolamines by treatment with gaseous sulfur dioxide can decrease. However, if the method is applied to the above detergents, so solutions that are cloudy and contain precipitates are obtained.
Es wurde nun gefunden, daß man Alkanolaminsalzlösungen und alkanolaminsalzhaltige Waschmittel vorteilhaft durch den Zusatz von Glykolsulfiten gegen Verfärbung stabilisieren kann. Geeignete Glykolsulfite sind beispielsweise ÄthylenglykolsulfitjPropylenglykolsulfit und 1,2- und 1,3-ButylenglykoIsulfit, die man in Mengen von 0,1 bis 10%, besonders aber von 0,5 bis 2%, bezogen auf die Alkanolaminsalzlösung, dem Waschmittel zusetzt. Durch die Zugabe von Glykolsulfiten zu Waschmitteln auf der Grundlage von Alkanolaminsalzen werden nicht nur bestehende Verfärbungen beseitigt, sondern auch eine lang anhaltende Stabilisierung gegen Verfärbung erreicht.It has now been found that alkanolamine salt solutions and detergents containing alkanolamine salts can be used can advantageously stabilize against discoloration by adding glycol sulfites. Suitable glycol sulfites Examples include ethylene glycol sulfite and propylene glycol sulfite and 1,2- and 1,3-butylene glycol sulfite, which are found in Amounts from 0.1 to 10%, but especially from 0.5 to 2%, based on the alkanolamine salt solution, the Adding detergent. By adding glycol sulfites to detergents based on Alkanolamine salts not only remove existing discoloration, but also a long-lasting one Stabilization against discoloration achieved.
Es ist bereits vorgeschlagen worden, Hydrazin zum Stabilisieren von Alkanolaminsalzlösungen zu verwenden. Der Zusatz von Glykolsufit ist jedoch besonders vorteilhaft, da hierdurch der pH-Wert vonIt has been proposed to use hydrazine to stabilize alkanolamine salt solutions. However, the addition of glycol sulfite is particularly advantageous because it reduces the pH value of

Alkanolaminsalzlösungen in das saure Gebiet verschoben wird und eine alkalische Reaktion, die bei kosmetischen Waschmitteln äußerst unerwünscht ist, vermieden wird. Weiterhin wird durch das aus dem Glykolsulfit beim Zerfall frei werdende Glykol, die Löslichkeit und das Reinigungsvermögen des Waschmittels günstig beeinflußt.Alkanolamine salt solutions will move into the acidic area and cause an alkaline reaction to occur cosmetic detergents is extremely undesirable, is avoided. Furthermore, the from the Glycolsulphite released during decomposition, the solubility and cleaning power of the detergent favorably influenced.
Eine 50%ige wäßrige Lösung des Triäthanolaminsalzes der Tetrapropylenbenzolsulfonsäure wird mit 0,5 und 1,0 % Glykolsulfit versetzt. Nach erfolgter Durchmischung zeigen die Lösungen bereits nach kurzem Stehen eine deutliche Aufhellung. Wie aus der Tabelle ersichtlich ist, erreichen sie bei längerer Lagerzeit eine Farbzahl, die derjenigen einer Lösung, die keinen Zusatz enthält, wesentlich überlegen ist.A 50% aqueous solution of the triethanolamine salt of tetrapropylenebenzenesulfonic acid is used with 0.5 and 1.0% glycol sulfite added. After thorough mixing, the solutions are already showing Shortly standing a clear brightening. As can be seen from the table, they achieve longer Storage time a color number that is significantly superior to that of a solution that does not contain any additive.
