Definitions
- the invention relates to scouring powders which at the same time offer a good cleaning action, in particular against greasy soiling, and develop only a little foam when used.
- Scouring powder is one of the oldest and still indispensable cleaning agents that are used in households and businesses to remove stubborn dirt.
- the basic constituents of scouring powders form, on the one hand, the abrasive particles required for the mechanical loosening of stubborn dirt and, on the other hand, surfactants as surface-active substances that are essential for the removal of greasy or greasy dirt.
- the scouring powders currently on the market contain almost exclusively alkylbenzenesulfonates as surfactants, as well as occasionally other active ingredients and auxiliary substances such as.
- German patent applications DE 25 39 733 A1 and DE 27 39 776 A1 describe liquid and powdered abrasives with an abrasive content of pearlite in an amount of up to 65%. These applications essentially focus on this special abrasive. Alkyl sulfates and alkylbenzenesulfonates are specified here as surfactants for the powdery compositions.
- Canadian patent 1,048,365 (Procter & Gamble) describes abrasive powders with a high surfactant content of 20-35% and an abrasive content of 5-20%, which are recommended as both abrasive powder and dishwashing detergent.
- Alkyl sulfates, alkylbenzenesulfonates and fatty alcohol ethoxylates are mentioned as surfactants.
- the common known and currently commercially available abrasive powders have a good cleaning ability as a common feature greasy and fatty dirt, but foams to an undesirably high degree when used. In order to avoid foaming, an attempt was even made to offer pure abrasives without any added surfactants.
- the object of the invention was therefore to provide the desired agents which combine the two product effects: good dirt removal and low foaming tendency.
- this object was achieved by adding alkyl glycosides with a degree of oligomerization of 1.2 to 1.4 or surfactant combinations containing these alkyl glycosides to the scouring powders, which scouring powders may also contain conventional ingredients.
- the invention therefore relates to low-foaming scouring powders containing abrasives, other customary constituents and optionally other surfactants, which are characterized in that they contain an addition of alkyl glycosides with a degree of oligomerization of 1.2 to 1.4.
- Alkylglososides are known to be degradable surfactants of native origin.
- the alkyl glycosides which can be used here as surfactants can be represented by the structural formula RO (G) x , where R is an aliphatic radical with at least 4 carbon atoms, in particular the radical of a primary alcohol and very particularly a fatty alkyl or fatty alkenyl radical with 8 to 22, preferably 12 to 18 carbon atoms.
- R is an aliphatic radical with at least 4 carbon atoms, in particular the radical of a primary alcohol and very particularly a fatty alkyl or fatty alkenyl radical with 8 to 22, preferably 12 to 18 carbon atoms.
- the symbol (G) in the formula stands for a glycose unit, glucose being preferred because of the technical availability on the one hand and the good reactivity on the other hand.
- the index number x is any number between 1.2 and 1.4, which means the so-called degree of oligomerization, ie the distribution of monoglycosides and oligoglycosides is specified.
- the alkyl glycosides are represented by the formula RO (G) x , the percentage of fatty alcohol is neglected. In principle, this fatty alcohol portion can largely be controlled by gentle distillative treatment of the alkyl glycoside, ie the excess fatty alcohol resulting from the reaction can be removed from the product except for residual values that are less than 1% total. They have been proposed for liquid manual dishwashing detergents, e.g. B.
- alkylbenzene sulfonate As anionic co-surfactants, alkylbenzene sulfonate, soap, zwitterionic surfactants, amphoteric surfactants, alkane sulfonates, alpha-olefin sulfonates, alkyl sulfates, alkyl polyglycol ether sulfates and paraffin sulfonates and mixtures thereof are mentioned in particular.
- the surfactant compositions described here are suitable for the production of products which foam strongly when used, such as, for example, manual dishwashing detergents and shampoos.
- the description also mentions a possible addition of abrasive substances enumeratively, but no examples are available.
- liquid, high-foaming cleaning agents for the manual cleaning of dishes are also known which, in addition to fatty alkyl glucosides with a degree of oligomerization of 1 to 1.4, serve as foam enhancers dialkyl sulfosuccinates with 7 to 9 carbon atoms in each of the alkyl residues contain. Again, there is no evidence of abrasives. It was therefore not foreseeable that this Alkyl glycosides alone or in combination with other surfactants in scouring powders show only a weak development of foam when used.
- alkyl sulfates alkyl ether sulfates, alkyl benzene sulfonates, alkyl sulfonates, etc., which are common for cleaning agents, in question.
- Alkyl sulfates which are prepared from natural oils and fats by known processes and have a saturated or unsaturated alkyl radical having 6-20, preferably 10-18 carbon atoms are preferred. Scouring powders which are free from alkylbenzenesulfonates are particularly preferred.
- Suitable nonionic surfactants are fatty alcohol ethoxylates, ie adducts of 2-16 mol ethylene oxide onto fatty alcohols with branched or straight-chain saturated or unsaturated C16-C20-alkyl radicals.
- Preferred fatty alcohol ethoxylates are those which are produced from natural fats and oils.
- conventional amphoteric surfactants and betaines and / or amido betaines can also be used in small amounts. If this class of surfactants is also used, the amount used is based on the possible amount Align the presence of other surfactants so that the overall formulation has the desired foaming behavior.
- All substances known for scouring powder e.g. B. mineral rock powders such as quartz, cristobalite, marble, pumice powder u. ⁇ . With a grain size up to 1 mm, preferably up to 0.3 mm, are used. The lower grain size is determined solely by the technical possibilities in the production of abrasive materials, also in the form of flour-like forms suitable for additions to polishing agents. Alternatively, plastic granules or powder as well as wood flour or glass beads and similar abrasives with a very mild abrasive effect can be used.

Abstract
Description
Die Erfindung betrifft Scheuerpulver, die gleichzeitig eine gute Reinigungswirkung insbesondere gegenüber fettigen Verschmutzungen bieten und bei der Anwendung nur wenig Schaum entwickeln.The invention relates to scouring powders which at the same time offer a good cleaning action, in particular against greasy soiling, and develop only a little foam when used.
Scheuerpulver gehören zu den ältesten und auch heute noch unentbehrlichen Reinigungsmitteln, die in Haushalt und Gewerbe zur Entfernung hartnäckiger Verschmutzungen verwendet werden. Die Grundbestandteile von Scheuerpulvern bilden zum einen die für die mechanische Auflockerung hartnäckigen Schmutzes benötigten Abrasivstoffteilchen und zum andern Tenside als grenzenflächenaktive Substanzen, die für die Entfernung fettigen oder fetthaltigen Schmutzes unerläßlich sind. Die derzeit auf dem Markt befindlichen Scheuerpulver enthalten als Tenside nahezu ausschließlich Alkylbenzolsulfonate, sowie fallweise weitere Wirk- und Hilfsstoffe wie z. B. Bleich- und Desinfektionsmittel, Zeolithe und alkalische Salze. In den deutschen Patentanmeldungen DE 25 39 733 A1 und DE 27 39 776 A1 (Procter & Gamble) werden flüssige und pulverförmige Scheuermittel mit einem Abrasivstoffanteil aus Perlit in einer Menge bis zu 65 % beschrieben. Diese Anmeldungen heben im wesentlichen auf diesen speziellen Abrasivstoff ab. Als Tenside für die pulverförmigen Mittel werden hier Alkylsulfate und Alkylbenzolsulfonate angegeben.Scouring powder is one of the oldest and still indispensable cleaning agents that are used in households and businesses to remove stubborn dirt. The basic constituents of scouring powders form, on the one hand, the abrasive particles required for the mechanical loosening of stubborn dirt and, on the other hand, surfactants as surface-active substances that are essential for the removal of greasy or greasy dirt. The scouring powders currently on the market contain almost exclusively alkylbenzenesulfonates as surfactants, as well as occasionally other active ingredients and auxiliary substances such as. B. bleach and disinfectants, zeolites and alkaline salts. The German patent applications DE 25 39 733 A1 and DE 27 39 776 A1 (Procter & Gamble) describe liquid and powdered abrasives with an abrasive content of pearlite in an amount of up to 65%. These applications essentially focus on this special abrasive. Alkyl sulfates and alkylbenzenesulfonates are specified here as surfactants for the powdery compositions.
In der kanadischen Patentschrift 1 048 365 (Procter & Gamble) werden scheuernd wirkende Pulver mit einem hohen Tensidgehalt von 20 - 35 % und einem Abrasivstoffgehalt von 5 - 20 %, die sowohl als Scheuerpulver als auch als Geschirrspülmittel gempfohlen werden, beschrieben. Als Tenside werden Alkylsulfate, Alkylbenzolsulfonate sowie Fettalkoholethoxilate genannt. Die literaturbekannten und die aktuell handelsüblichen Scheuerpulver haben als gemeinsames Merkmal ein gutes Reinigungsvermögen gegenüber fettigem und fetthaltigem Schmutz, schäumen jedoch bei der Anwendung in einem unerwünscht hohen Maß. Um das Schäumen zu vermeiden, wurde sogar der Versuch unternommen, reine Abrasivstoffe ohne jeglichen Tensidzusatz anzubieten. Derartige Scheuerpulver besitzen jedoch keine fettentfernende Wirkung und verhalten sich darüber hinaus bei der Anwendung aufgrund fehlender Dispergierwirkung völlig unbefriedigend. Der Wunsch der Anwender nach nur schwach schäumenden, aber gut reinigenden Scheuerpulvern konnte bisher nicht erfüllt werden.Canadian patent 1,048,365 (Procter & Gamble) describes abrasive powders with a high surfactant content of 20-35% and an abrasive content of 5-20%, which are recommended as both abrasive powder and dishwashing detergent. Alkyl sulfates, alkylbenzenesulfonates and fatty alcohol ethoxylates are mentioned as surfactants. The common known and currently commercially available abrasive powders have a good cleaning ability as a common feature greasy and fatty dirt, but foams to an undesirably high degree when used. In order to avoid foaming, an attempt was even made to offer pure abrasives without any added surfactants. Such scouring powders, however, have no fat-removing effect and, moreover, behave completely unsatisfactorily when used due to the lack of dispersing action. So far, the users' wish for scouring powders which only have a low foaming but are easy to clean has not been fulfilled.
Die Aufgabe der Erfindung bestand daher darin, die gewünschten Mittel bereitzustellen, die die beiden Produktwirkungen: gute Schmutzentfernung und geringe Schaumneigung, in sich vereinigen.The object of the invention was therefore to provide the desired agents which combine the two product effects: good dirt removal and low foaming tendency.
Überraschenderweise konnte diese Aufgabe dadurch gelöst werden, daß man den Scheuerpulvern Alkylglycoside mit einem Oligomerisierungsgrad von 1,2 bis 1,4 oder Tensid-Kombinationen mit einem Gehalt an diesen Alkylglycosiden zusetzt, wobei die Scheuerpulver darüber hinaus übliche Inhaltsstoffe enthalten können.Surprisingly, this object was achieved by adding alkyl glycosides with a degree of oligomerization of 1.2 to 1.4 or surfactant combinations containing these alkyl glycosides to the scouring powders, which scouring powders may also contain conventional ingredients.
Die Erfindung betrifft daher schwachschäumende Scheuerpulver mit einem Gehalt an Abrasivstoffen, sonstigen üblichen Bestandteilen und gegebenenfalls sonstigen Tensiden, die dadurch gekennzeichnet sind, daß sie einen Zusatz an Alkylglycosiden mit einem Oligomerisierungsgrad von 1,2 bis 1,4 enthalten.The invention therefore relates to low-foaming scouring powders containing abrasives, other customary constituents and optionally other surfactants, which are characterized in that they contain an addition of alkyl glycosides with a degree of oligomerization of 1.2 to 1.4.
Alkylglfloside sind als abbaubare Tenside nativen Ursprungs bekannt. Generell können die hier als Tenside brauchbaren Alkylglykoside durch die Strukturformel RO(G)x wiedergegeben werden, wobei R einen aliphatischen Rest mit wenigstens 4 Kohlenstoffatomen, insbesondere den Rest eines primären Alkohols und ganz besonders einen Fettalkyl- oder Fettalkenyl-Rest mit 8 bis 22, vorzugsweise 12 bis 18 Kohlenstoffatomen, bedeutet. Das Symbol (G) in der Formel steht für eine Glykoseeinheit, wobei wegen der technischen Verfügbarkeit einerseits und der guten Reaktionsfähigkeit andererseits die Glucose bevorzugt ist. Schließlich ist die Indexzahl x eine beliebige Zahl zwischen 1,2 und 1,4, womit der sogenannte Oligomerisierungsgrad, d. h. die Verteilung von Monoglykosiden und Oligoglykosiden angegeben wird. Bei der Wiedergabe der Alkylglykoside durch die Formel RO(G)x wird der Fettalkoholanteil vernachlässigt. Dieser Fettalkoholanteil kann prinzipiell weitgehend durch schonende destillative Behandlung des Alkylglykosids gesteuert werden, d. h. der aus der Reaktion stammende Fettalkoholüberschuß kann bis auf Restwerte, die unter 1 % Gesamtanteil liegen, aus dem Produkt entfernt werden. Sie wurden u. a. für flüssige manuelle Geschirrspülmittel vorgeschlagen, z. B. in WO 86/02943 (A.E.Staley) und WO 89/02912 (Henkel Corp.). Von manuellen Geschirrspülmitteln wird aber im Gegensatz zum Gebiet anderer Reinigungsmittel für harte Oberflächen vom Verbraucher ein hohes Schäumvermögen gefordert. Eine schäumende Tensidzusammensetzung, die ein spezielles tensidisches Alkylglykosid mit dem Oligomerisierungsgrad x = 1,5 bis 10 und mit einem Alkylmonoglykosidgehalt von 20 bis 70 Gew.-%, zusammen mit einem anionischen Co-Tensid, das aus der Gruppe der tensidischen Sulfate, Sulfonate, Carboxylate und deren Mischungen ausgewählt ist, wird in der EP 0 070 074 A2 (Procter & Gamble) beschrieben. Als anionische Co-Tenside werden insbesondere Alkylbenzolsulfonat, Seife, zwitterionische Tenside, amphotere Tenside, Alkansulfonate, Alpha-Olefinsulfonate, Alkylsulfate, Alkylpolyglykolethersulfate und Paraffinsulfonate und deren Mischungen erwähnt. Die hier beschriebenen Tensidzusammensetzungen sind für die Herstellung von Produkten, die bei der Anwendung stark schäumen, wie beispielsweise manuellen Geschirrspülmitteln und Shampoos, geeignet. In der Beschreibung wird enumerativ auch ein möglicher Zusatz an Abrasivstoffen erwähnt, Beispiele dafür liegen jedoch nicht vor. Aus der DE 35 34 082 A1 (Henkel KGaA) sind flüssige Reinigungsmittel für das manuelle Reinigen von Geschirr bekannt, die Sulfat- und/oder Sulfonattenside, Fettsäurealkanolamide und Fettalkylglucoside mit einem Oligomerisierungsgrad von 1 bis 1,4 enthalten, die besondere Schaum- und Reinigungskraft aufweisen. Scheuermittel werden dort nicht beschrieben.Alkylglososides are known to be degradable surfactants of native origin. In general, the alkyl glycosides which can be used here as surfactants can be represented by the structural formula RO (G) x , where R is an aliphatic radical with at least 4 carbon atoms, in particular the radical of a primary alcohol and very particularly a fatty alkyl or fatty alkenyl radical with 8 to 22, preferably 12 to 18 carbon atoms. The symbol (G) in the formula stands for a glycose unit, glucose being preferred because of the technical availability on the one hand and the good reactivity on the other hand. Finally, the index number x is any number between 1.2 and 1.4, which means the so-called degree of oligomerization, ie the distribution of monoglycosides and oligoglycosides is specified. When the alkyl glycosides are represented by the formula RO (G) x , the percentage of fatty alcohol is neglected. In principle, this fatty alcohol portion can largely be controlled by gentle distillative treatment of the alkyl glycoside, ie the excess fatty alcohol resulting from the reaction can be removed from the product except for residual values that are less than 1% total. They have been proposed for liquid manual dishwashing detergents, e.g. B. in WO 86/02943 (AEStaley) and WO 89/02912 (Henkel Corp.). In contrast to the field of other cleaning agents for hard surfaces, however, manual dishwashing detergents demand high foaming power from the consumer. A foaming surfactant composition that contains a special surfactant alkyl glycoside with the degree of oligomerization x = 1.5 to 10 and with an alkyl monoglycoside content of 20 to 70 wt. Carboxylates and mixtures thereof is selected is described in EP 0 070 074 A2 (Procter & Gamble). As anionic co-surfactants, alkylbenzene sulfonate, soap, zwitterionic surfactants, amphoteric surfactants, alkane sulfonates, alpha-olefin sulfonates, alkyl sulfates, alkyl polyglycol ether sulfates and paraffin sulfonates and mixtures thereof are mentioned in particular. The surfactant compositions described here are suitable for the production of products which foam strongly when used, such as, for example, manual dishwashing detergents and shampoos. The description also mentions a possible addition of abrasive substances enumeratively, but no examples are available. DE 35 34 082 A1 (Henkel KGaA) discloses liquid detergents for the manual cleaning of dishes, which contain sulfate and / or sulfonate surfactants, fatty acid alkanolamides and fatty alkyl glucosides with a degree of oligomerization of 1 to 1.4, the particular foam and cleaning power exhibit. Abrasives are not described there.
Aus der DE 37 06 015 A1 (Henkel KGaA) sind weiterhin flüssige, stark schäumende Reinigungsmittel für das manuelle Reinigen von Geschirr bekannt, die neben Fettalkylglucosiden mit einem Oligomerisierungsgrad von 1 bis 1,4 als Schaumverstärker Dialkylsulfosuccinate mit 7 bis 9 Kohlenstoffatomen in jedem der Alkylreste enthalten. Auch hier findet sich kein Hinweis auf Scheuermittel. Es war daher nicht voraussehbar, daß diese Alkylglykoside allein oder in Kombination mit weiteren Tensiden in Scheuerpulvern eine nur schwache Schaumentwicklung bei Anwendung zeigen.From DE 37 06 015 A1 (Henkel KGaA), liquid, high-foaming cleaning agents for the manual cleaning of dishes are also known which, in addition to fatty alkyl glucosides with a degree of oligomerization of 1 to 1.4, serve as foam enhancers dialkyl sulfosuccinates with 7 to 9 carbon atoms in each of the alkyl residues contain. Again, there is no evidence of abrasives. It was therefore not foreseeable that this Alkyl glycosides alone or in combination with other surfactants in scouring powders show only a weak development of foam when used.
Bevorzugte Scheuerpulver der vorliegenden Erfindung weisen die folgende Zusammensetzung auf:
- a) 70 - 99 Gew.-%, insbesondere 80 - 95 Gew.-% eines Abrasivstoffes,
- b) 0,5-15 Gew.-%, insbesondere 1 - 10 Gew.-% eines Tensids oder einer Tensidmischung aus der Gruppe der Anion-, Nio- oder Amphotenside, wobei dieses Tensid bzw. diese Tensidmischung zu 2 -100 %, vorzugsweise zu 5 - 90 % aus dem Alkylglucosid besteht und
- c) der Rest auf 100 Gew.-% üblicherweise in Scheuerpulvern verwendete Stoffe wie Bleich- und Desinfektionsmittel, anorganische oder organische wasserlösliche oder unlösliche Salze, Farb- und Duftstoffe.
- a) 70-99% by weight, in particular 80-95% by weight, of an abrasive,
- b) 0.5-15% by weight, in particular 1-10% by weight, of a surfactant or a surfactant mixture from the group of anionic, nio- or amphoteric surfactants, with this surfactant or this surfactant mixture being 2-100%, preferably consists of 5-90% of the alkyl glucoside and
- c) the remainder to 100% by weight of substances usually used in scouring powders, such as bleaching and disinfecting agents, inorganic or organic water-soluble or insoluble salts, colorants and fragrances.
Als weitere Tenside, die in den erfindungsgeäßen Scheuerpulvern eingesetzt werden können, kommen Aniontenside vom Sulfat und Sulfonattyp, wie z. B. Alkylsulfate, Alkylethersulfate, Alkylbenzolsulfonate, Alkylsulfonate usw., die für Reinigungsmittel gebräuchlich sind, in Frage. Bevorzugt sind Alkylsulfate, die aus natürlichen Ölen und Fetten nach bekannten Verfahren hergestellt werden und einen gesättigten oder ungesättigten Alkylrest mit 6 - 20, vorzugsweise 10 - 18 Kohlenstoffatomen aufweisen. Besonders bevorzugt sind Scheuerpulver, die frei sind von Alkylbenzolsulfonaten.Other surfactants that can be used in the scouring powders according to the invention are anionic surfactants of the sulfate and sulfonate type, such as. As alkyl sulfates, alkyl ether sulfates, alkyl benzene sulfonates, alkyl sulfonates, etc., which are common for cleaning agents, in question. Alkyl sulfates which are prepared from natural oils and fats by known processes and have a saturated or unsaturated alkyl radical having 6-20, preferably 10-18 carbon atoms are preferred. Scouring powders which are free from alkylbenzenesulfonates are particularly preferred.
Als Niotenside kommen Fettalkoholethoxilate, d. h. Anlagerungsprodukte von 2 - 16 Mol Ethylenoxid an Fettalkohole mit verzweigten oder geradkettigen gesättigten oder ungesättigten C16-C20-Alkylresten. Bevorzugt sind solche Fettalkoholethoxilate, die aus natürlichen Fetten und Ölen hergestellt werden. In geringen Mengen können gegebenenfalls auch übliche Amphotenside und Betaine und/oder Amidobetaine eingesetzt werden. Bei Mitverwendung dieser Tensidklasse ist aber deren Einsatzmenge auf die eventuelle Anwesenheit weiterer Tenside auszurichten, so daß die Gesamtformulierung das gewünschte Schaumverhalten aufweist.Suitable nonionic surfactants are fatty alcohol ethoxylates, ie adducts of 2-16 mol ethylene oxide onto fatty alcohols with branched or straight-chain saturated or unsaturated C16-C20-alkyl radicals. Preferred fatty alcohol ethoxylates are those which are produced from natural fats and oils. If desired, conventional amphoteric surfactants and betaines and / or amido betaines can also be used in small amounts. If this class of surfactants is also used, the amount used is based on the possible amount Align the presence of other surfactants so that the overall formulation has the desired foaming behavior.
Als Abrasiva können alle für Scheuerpulver bekannten Stoffe, z. B. mineralische Gesteinsmehle, wie Quarz-, Cristobalit-, Marmor-, Bimsmehl u. ä. mit einer Korngröße bis zu 1 mm, bevorzugt bis zu 0,3 mm, eingesetzt werden. Die untere Korngröße wird allein durch die technischen Möglichkeiten bei der Herstellung von Abrasivstoffen, auch in Form von für Poliermittelzusatze geeigneten mehlartigen Formen, bestimmt. Es können alternativ auch Kunststoffgranulate bzw. -pulver sowie Holzmehl oder Glasperlen und ähnliche Abrasiva mit sehr milder Scheuerwirkung verwendet werden.All substances known for scouring powder, e.g. B. mineral rock powders such as quartz, cristobalite, marble, pumice powder u. Ä. With a grain size up to 1 mm, preferably up to 0.3 mm, are used. The lower grain size is determined solely by the technical possibilities in the production of abrasive materials, also in the form of flour-like forms suitable for additions to polishing agents. Alternatively, plastic granules or powder as well as wood flour or glass beads and similar abrasives with a very mild abrasive effect can be used.
Als Bleich- und Desinfektionsmittel sind die bekannten anorganischen oder organischen, in Gegenwart von Wasser H₂O₂ oder Aktivchlor liefernden Verbindungen brauchbar. Die Perverbindungen können zusammen mit sogenannten Bleichaktivatoren, wie z.B. Tetraacetyl-äthylendiamin oder Tetraacetylglykoluril eingesetzt werden.The known inorganic or organic compounds which provide H₂O₂ or active chlorine in the presence of water can be used as bleaching and disinfecting agents. The per-compounds can be used together with so-called bleach activators, e.g. Tetraacetyl-ethylenediamine or tetraacetylglycoluril can be used.
Zu weiteren, gegebenenfalls in Scheuerpulvern verwendbaren Stoffen zählen anorganische oder organische Komplexbildner und Gerüstsubstanzen, die in der Lage sind, Erdalkaliionen des Leitungswassers, welches zur Anwendung der Scheuerpulver verwendet wird, zu binden und die mit den Tensiden zu einer Steigerung der Reinigungswirkung führen. Zu dieser Klasse an Wirkstoffen zählen die bekannten Zeolithe sowie organische Komplexbildner, insbesondere die Natriumsalze der Polycarbonsäuren, Hydroxycarbonsäuren, Aminocarbonsäuren, Carboxyalkylethern, polyanionische Polymere, insbesondere der polymeren Carbonsäuren. P-haltige Komplexbildner oder Gerüstsubstanzen sollen vorzugsweise nicht eingesetzt werden.Other substances that can possibly be used in scouring powders include inorganic or organic complexing agents and builders that are able to bind alkaline earth ions in the tap water that is used to apply the scouring powder and that lead to an increase in the cleaning effect with the surfactants. This class of active ingredients includes the known zeolites and organic complexing agents, in particular the sodium salts of polycarboxylic acids, hydroxycarboxylic acids, aminocarboxylic acids, carboxyalkyl ethers, polyanionic polymers, in particular polymeric carboxylic acids. P-containing complexing agents or builders should preferably not be used.
Schließlich kann es erwünscht sein, den Scheuerpulvern neutral oder alkalisch reagierende Alkalisalze, insbesondere Natriumsalze, aus der Gruppe der Chloride, Carbonate, Bicarbonate, Sulfate und Silikate hinzuzufügen.Finally, it may be desirable to add neutral or alkaline alkaline salts, in particular sodium salts, from the group of chlorides, carbonates, bicarbonates, sulfates and silicates to the scouring powders.
Die erfindungsgemäßen Scheuerpulver können ferner Farb- und Duftstoffe enthalten. Im Falle der Anwesenheit von oxidativ wirkenden Bleichmitteln wählt man bekannte oxidationsstabile Farbpigmente wie Phthalocyaninpigmente oder Ultramarin und Duftstoffe wie Terpenverbindungen aus.The scouring powders according to the invention can also contain colorants and fragrances. In the presence of oxidative bleaching agents Known oxidation-stable color pigments such as phthalocyanine pigments or ultramarine and fragrances such as terpene compounds are selected.
Die Herstellung der Scheuerpulver kann in an sich bekannter Weise erfolgen, z. B. durch Trocknen eines Teils oder aller wasserlöslicher Komponenten und Zumischen bzw. Aufsprühen der restlichen Komponenten des Scheuerpulvers.The scouring powder can be prepared in a manner known per se, e.g. B. by drying part or all of the water-soluble components and admixing or spraying on the remaining components of the scouring powder.
Die Prüfung der Reinigungswirkung der erfindungsgemäßen Scheuerpulver erfolgte nach der in der Fachzeitschrift Seifen - Öle - Fette - Wachse, 112, 371 (1986) veröffentlichten Methode. Dabei wurde das zu prüfende Reinigungsmittel auf eine künstlich angeschmutzte Kunststoffoberfläche gegeben. Als künstliche Anschmutzung diente eine Mischung aus Vaseline (R), Fettsäureglycerinestern und Pigmenten eingesetzt. Die Testfläche von 26 x 28 cm wurde mit Hilfe eines Flächenstreichers gleichmäßig mit 2 g der künstlichen Anschmutzung beschichtet.The cleaning effect of the scouring powders according to the invention was tested according to the method published in the trade journal Seifen - Öle - Fette - Wachsen, 112, 371 (1986). The cleaning agent to be tested was placed on an artificially soiled plastic surface. A mixture of petroleum jelly (R), fatty acid glycerol esters and pigments was used as artificial soiling. The test area of 26 x 28 cm was evenly coated with 2 g of the artificial soiling with the aid of a surface coater.
Ein Kunststoffschwamm wurde mit Leitungswasser getränkt. Auf die Testfläche wurde das zu prüfende Scheuerpulver als 1 : 1 -Mischung mit Leitungswasser aufgetragen. Der Schwamm wurde dann mechanisch auf der Testfläche bewegt. Nach zehn Wischbewegungen wurde die gereinigte Testfläche unter fließendes Wasser gehalten und der lose sitzende Schmutz entfernt. Die Reinigungswirkung, d. h. der Weißgrad der so gereinigten Kunststoffoberfläche wurde mit einem Farb-Differenz-Meßgerät Microcolor der Firma Dr. Lange gemessen. Als Weiß-Standard diente die saubere weiße Kunststoffoberfläche.A plastic sponge was soaked in tap water. The scouring powder to be tested was applied to the test area as a 1: 1 mixture with tap water. The sponge was then moved mechanically on the test surface. After ten wiping movements, the cleaned test area was kept under running water and the loose dirt was removed. The cleaning effect, d. H. the whiteness of the plastic surface cleaned in this way was determined using a Microcolor color difference measuring device from Dr. Measured for a long time. The clean white plastic surface served as the white standard.
Da bei der Messung der sauberen Oberfläche auf 100 % eingestellt und die angeschmutzte Fläche mit 0 angezeigt wurde, sind die abgelesenen Werte bei den gereinigten Kunststoff-Flächen mit dem Prozentgehalt Reinigungsvermögen (% RV) gleichzusetzen. Bei den nachstehenden Versuchen sind die angegebenen Werte RL rel. (%) die nach dieser Methode ermittelten Werte für das Reinigungsvermögen der untersuchten Reinigungsmittel, bezogen auf die Reinigungsleistung des Vergleichsstandards (RL = 100 %). Sie stellen jeweils Mittelwerte aus 3fachen Bestimmungen dar.Since the measurement of the clean surface was set to 100% and the soiled area was displayed with 0, the read values for the cleaned plastic areas are to be equated with the percentage of cleaning ability (% RV). In the experiments below, the values RL rel. (%) the values determined according to this method for the cleaning ability of the investigated cleaning agents, based on the Cleaning performance of the comparison standard (RL = 100%). They represent mean values from triplicate determinations.
Das Schaumverhalten wurde praxisnah nach folgender Methode überprüft, wobei der Schaum, der beim Scheuern entsteht, auf einem sauberen gekachelten Tisch geprüft wurde. Für den Schaumtest wurden 1,0 g Scheuerpulver und 10 ml Leitungswasser auf den Tisch gegeben. Man scheuerte in 15 Kreisbewegungen mit angefeuchteten Handbürsten und beurteilte den gebildeten Schaum in Noten von 1 - 4, wobei 4 = sehr viel Schaum und 1 = kein oder nur sehr wenig Schaum bedeuten.The foam behavior was checked in a practical manner using the following method, the foam which is produced when scrubbing being checked on a clean tiled table. For the foam test, 1.0 g scouring powder and 10 ml tap water were placed on the table. It was scrubbed in 15 circular movements with moistened hand brushes and the foam formed was rated in grades of 1 to 4, 4 = very much foam and 1 = no or very little foam.
