Abstract

Dish-washing machine detergent compsn., having reduced pH and lower silicate content, contains esp. 0.5-5 (1-3) wt.% Al soap of a 12-24 C fatty acid, partic. Al stearate, as corrosion inhibitor. The compsns. pref. contain water-glass, e.g. in proportions of at least 5%. The water-glass can replace standard meta-silicates used. The Al soaps resist storage, do not decompose in the presence of alkaline components, dissolve quickly in washing liquor and react with the silicate present to form a colloidal Al silicate. Dish-decoration damage and glass attacks are prevented.

Description

"Geschirrspülmittel mit Korrosionsschutzmittel" Die vorliegende Erfindung bezieht sich auf ein H Maschinengeschirrspülmittel mit einem bestimmten Korrosionsschutzmittel Bekanntlich werden den ublichen, hochalkalischen Maschinengeschirrspülmitteln Korrosionsschutzmittel zugesetzt, damit dem Angriff des Dekors des Geschirrs durch diese hochalkalisohen Maschinengeschirrspülmittel vorgebeugt wird0 Es sind schon verschiedene Korrosionsschutzmittel für diesen Zweck bekannt, und das bekannteste dieser Hittel ist Natriumaluminat. Diese Verbindung führt jedoch zu bestimmten Nachteilen; insbeaondere ubt sie eine negative Wirkung auf die Stärkeontfernung aus. "Dishwashing detergent with anti-corrosive agent" The present invention refers to an H machine dishwashing detergent with a specific anti-corrosive agent It is well known that the usual, highly alkaline machine dishwashing detergents are anti-corrosion agents added, so that the attack of the decor of the dishes by these high alkalis Machine dishwashing detergent is prevented0 There are already various anti-corrosion agents known for this purpose, and the best known of these agents is sodium aluminate. However, this connection leads to certain disadvantages; she especially practices one negative effect on starch removal.

Auch das meistens in hochalkalischen Maschinengeschirrspülmitteln vorhandene Sili kat übt eine gewisse Korrosionsschutzwirkung aus; eine Erniedrigung des Silikatgehaltes zum Erhalt eines Maschinengeschirrspülmittels mit einem niedrigeren PH bringt einen erhöhten Dekorangriff mit sich, und in solchen Maschinengeschirrspülmitteln iat ein wirksames Korrosionsschutzmittel also sehr erforderlich.This is also mostly done in highly alkaline machine dishwashing detergents Existing Sili kat exerts a certain anti-corrosion effect; a humiliation the silicate content to obtain a machine dishwashing detergent with a lower PH brings with it an increased attack on decor, and in such machine dishwashing detergents An effective anti-corrosive agent is therefore very necessary.

Ea war daher Aufgabe der vorliegenden Erfindung, ein Korrosionsschutzmittel zu beschaffen1 das isgerstabil ist, sich in Kontakt mit den anderen alkalischen Inhaltsstoffen des Maschinengeschirrspülmittels nicht zersetzt1 das sich schnell in der Spülflotte lost und mit dein vorhandenen Silikat zur Bildung eines kolloidalen Aluminiumsilikats reagiert.It was therefore an object of the present invention to provide a corrosion protection agent to procure1 that is stable to eating, in contact with the other alkaline Ingredients of the dishwasher detergent do not decompose1 that quickly dissolved in the washing liquor and with your existing silicate to form a colloidal Aluminum silicate reacts.

Diese Aufgabe wurde erfindungsgemäss nun dadurch gelost1 dass gefunden wurde1 dass Aluminiumfettsaureseifen dieaen Erfordernissen genugen. Diese Seifen sind von C12-C24-Fettsäuren abgeleitet worden1 und Aluminiumsteorat hat sich als besonders geeignet erwiesen.According to the invention, this object has now been achieved by having found It was found that aluminum fatty acid soaps meet the requirements. These soaps have been derived from C12-C24 fatty acids1 and aluminum steroid has been found to be proved particularly suitable.

Die Erfindung betrifft somit Maschinengeschirrspülmittel mit erniedrigtem pH und verringertem Silikatgehalt, und einer Aluminiumverbindung als Korrosionsschutzmittel dadurch gekennzeichnet, dass die Aluminiumverbindung eine Aluminiumseife ist, insbesondere Aluminiumstearat.The invention thus relates to machine dishwashing detergents with reduced pH and reduced silicate content, and an aluminum compound as a corrosion protection agent characterized in that the aluminum compound is an aluminum soap, in particular Aluminum stearate.

Die Aluminiumverbindung wird in einer Menge von 0,5-5, insbesondere 1-3 Gew.% verwendet. Das Maschinengeschirrspülmittel enthalt die ublichen Bestandteile1 wie alkalische Salze (z.B. Natriumtripolyphosphat, Soda, Silikate), Chlorbleichmittel, nichtionogene Tensides Parfums usw Es hat sich gezeigt, dass die Anwesenheit von Wasserglas, z.B. in einer Menge von 5% oder mehr erwünscht ist, da dadurch die Bildung des kolloidalen Aluminiumsilikats ermöglicht wird, Demzufolge kann das übliche Metasilikat ganz oder teilweise durch Wasserglas ersetzt werden.The aluminum compound is used in an amount of 0.5-5, in particular 1-3% by weight used. The dishwasher detergent contains the usual ingredients1 such as alkaline salts (e.g. sodium tripolyphosphate, soda, silicates), chlorine bleach, non-ionic surfactants perfumes, etc It has been shown that the The presence of water glass, e.g. in an amount of 5% or more, is desirable, since this enables the colloidal aluminum silicate to be formed, consequently the usual metasilicate can be completely or partially replaced by water glass.

Die Erfindung wird nun anhand nachstehenden Beispiels naher erörtert.The invention will now be discussed in more detail using the following example.

Beispiel In einem 5 1 - Becherglas wurden die beiden Hälften eines Maastricht-Testdekortellers senkrecht in 4,5 1 Reinigungslauge (Konzentration 3g/l in permutiertem Wasser) eingehängt. Unter ständigem Rühren bei 65°C wurde der Teller insgesamt 5 x 8 Stunden in der Lauge belassen, vobei die Lauge nach Je 8 Stunden erneuert wurde. Die Beurteilung der Korrosion erfolgte nach 16, 32 und 4D Stunden.Example In a 5 liter beaker, the two halves became one Maastricht test decorative plate vertically in 4.5 1 cleaning solution (concentration 3g / l suspended in permuted water). With constant stirring at 65 ° C, the plate was Leave a total of 5 x 8 hours in the lye, the lye after every 8 hours has been renewed. The corrosion was assessed after 16, 32 and 4D hours.

Gleiches wurde mit Südwein- und Whiakyglasern durchgefuhrt.The same was done with Südwein and Whiaky glasses.

Die Beurteilung wurde gemäss folgenden Noten ausgewertet: Art des Dekorschadens: Note 1 = Farbaufhellung; Glanzverlust 2 = Farbe abreibbar; ist fleckig 3 = Untergrund sichtbar; Farbe völlig abgelöst Starke des Schadens: Note 1 = sehr schwach bis schwach 2 = mittelmässig bis stark 3 = stark biß sehr stark.The assessment was evaluated according to the following grades: Type of Decor damage: grade 1 = color lightening; Loss of gloss 2 = color can be rubbed off; is spotty 3 = background visible; Color completely peeled off. Severity of the damage: Grade 1 = very weak to weak 2 = moderate to strong 3 = strong bit very strong.

Die Summe der beiden Noten wurde durch 10 dividiert, was die Endnote fur die Dekorkorrosion ergibt.The sum of the two grades was divided by 10, which is the final grade for decorative corrosion.

Für die Glaser gilt folgende Beurteilung: Note 1 , kein Schaden 2 = s@hr schwacher Schaden 3 = schwacher Schaden k = etwas Schaden 5 = deutlicher Schaden 6 = starker Schaden 7 = sehr starker Schaden Alle erhaltenen Sinzelnoten wurden summiert und durch die Anzahl der abgegebenen Beurteilungen dividiert0 Das Maschinengeschirrspülmittel hatte folgende Zusammensetzung: A B niohtionogenes Tensid 1s0 1,0 Chlorbleichmittel 1,5 1,4 Parfüm 0X1 0s1 Soda 510 51,6 Natriumtripolyphosphat (Trockansubst.) 40,0 37,4 Wasserglas (Trockensubst.) - 5,0 Wasser 2,4 3,0 Natriummetasilikat 5010 -Aluminiumstearat - 1,0 Die Beurteilung ergab folgendes: I Produkte 1 Einwirkungr inwirkuags- mM ~ : zeit 16 Stunden 0,01 1X3 O 1,3 32 Stunden 0X03 1,5 0 1,3 40 Stunden 0,10 2§0 O 1,3 Dies zeigt die Korrosionsschutzwirkung des Aluminiumstearats. Bei Verwendung von 0,75% des leichtlöslichen Natriumaluminats werden Filmbildung und die Verschlechterung der Reinigungswirkung, sowie Glastrübungen beobachtet.The following assessment applies to the glaziers: Grade 1, no damage 2 = s @ hr weak damage 3 = weak damage k = some damage 5 = significant damage 6 = heavy damage 7 = very heavy damage All individual grades received were summed up and divided by the number of 0 The dishwasher detergent had the following composition: AB nonionogenic surfactant 1s0 1.0 chlorine bleach 1.5 1.4 perfume 0X1 0s1 soda 510 51.6 sodium tripolyphosphate (dry substance) 40.0 37.4 water glass (dry substance) - 5, 0 water 2.4 3.0 sodium metasilicate 5010 aluminum stearate - 1.0 The assessment resulted in the following: I.
