Definitions
- the present invention relates to a liquid detergent concentrate which is essentially free of skeletal salts and which, owing to its composition, has an improved washing action compared to bleachable stains despite the absence of oxidative bleaching agents and, in conjunction with specially selected fatty acid diethanolamides, has textile-softening and grip-improving properties, so that the textiles washed therewith have no post-treatment with a special finishing agent.
- a second problem is the improvement in the grip of the washed textiles. It is known from the magazine "Soap and Chemical Specialties", November 1958, pages 48 to 50, that certain stearic acid derivatives of alkylolamines are used as softening agents in textile treatment agents. The problems of how such compounds behave or can be used in detergent-containing detergents are not dealt with in this publication. Furthermore, it has been shown that the stearic acid derivatives cannot be used in an effective amount in storage-stable liquid detergents.
- liquid detergent formulations which have more or less large contents of fatty acid mono- or diethanolamides. These are always those alkanolamides which are derived from fatty acid mixtures with a high proportion of C12-C16 fatty acids, for example coconut fatty acids. These alkanolamides are said to increase washing and foaming power or to improve skin tolerance. These remedies do not have an aviva effect.
- Examples of such agents are those according to DE-B-1 047 973, DE-C-2 022 064, DE-C-2 703 998 (US-A-4 153 570), DE-A-2 819 455, DE -C-3 022 767, DE-A-3 161 222, EP-A-38 101, US-A-2 861 956, US-A-2 943 058.
- EP-A-157 320 discloses a detergent which contains anionic or nonionic surfactants and a combination consisting of silicone-containing foam inhibitors and nitrogen-containing compounds from the class of ethoxylated fatty amines and fatty acid ethanolamides. These are preferably derived from coconut fatty acids and act as a detergency booster. They do not have an anti-sagging effect, and their proportion is comparatively low at less than 5% by weight, preferably less than 4% by weight. According to EP-A-151 678, liquid detergents contain 0 to 5% by weight of a "cosurfactant" consisting of surface-active quaternary salts, tertiary amines or amoxides. Textile softening fatty acid diethanolamides are not mentioned in the document.

- the proportion of the linear sodium alkylbenzenesulfonate (a) is at least 6% by weight, preferably up to 10% by weight. Dodecylbenzenesulfonate is preferably used.
- Suitable nonionic ethoxylated alcohols are fatty alcohols or oxo alcohols with 12 to 18, preferably 12 to 16, carbon atoms which are methyl-branched in the 2-position.
- the number of attached ethylene oxide groups (EO) is 5 to 10.
- Ethoxylated alcohols whose HLB value is 9 to 14, in particular 11 to 13.5, have proven to be very suitable. Examples of this are ethoxylated coconut fatty alcohols, from which the preliminary alcohols (10 and fewer carbon atoms) are separated and essentially consist of lauryl and myristyl alcohol in addition to small amounts of cetyl and stearyl alcohol.
- ethoxylated oxo alcohols or alcohols produced by ethylene polymerization which essentially consist of alcohol mixtures with 12 to 16 carbon atoms.

- Soaps of coconut fatty acids are particularly suitable, of which the fatty acids with less than 12 carbon atoms and more than 14 carbon atoms in a proportion of less than 10% by weight, preferably less than 5% by weight (based on the fatty acid mixture) are separated.
- the soaps of oleic acid or fatty acid mixtures rich in oleic acid are also suitable.
- the latter can contain up to 30% of polyunsaturated fatty acids with 18 carbon atoms or palmitoleic acid, but not more than 15% by weight, preferably not more than 10% by weight, of saturated C16-1s fatty acids, combinations of the above Soaps preferably consist of 20 to 50% by weight of oleic acid soap and 80 to 50% of C 12 -C 14 fatty acid soap, the content of the soap mixtures of saturated fatty acid soaps with more than 14 C atoms being less than 15% by weight , preferably at most 10 wt .-% and that of fatty acids with less than 12 carbon atoms is at most 5 wt .-%.
- the weight ratio of lauric acid soap to myristic acid soap is preferably 3: 2 to 4: 1.
- These soap mixtures are preferably in the form of the sodium soaps or as mixtures of sodium soaps and triethanolamine soaps.
- the proportion of soaps (c) is 16.1 to 22% by weight, preferably 16.5 to 20% by weight, in each case based on the fatty acid content.
- Component (d) includes fatty acid diethanolamides which are derived from monounsaturated fatty acids with 16 to 18 carbon atoms and their mixtures with saturated fatty acids of the same chain length, but the proportion of unsaturated compounds is at least 50% by weight, preferably at least 65% .-%.
- Diethanolamides derived from oleic acid and palmitoleic acid and mixtures thereof with the corresponding palmitic acid and stearic acid derivatives such as those obtained from naturally occurring fatty acid mixtures rich in oleic acid, e.g. B. from tallow fatty acids or tall oil fatty acids, are accessible by isolating the unsaturated portions by known separation processes (network separation).
- Well usable fatty acid fractions contain e.g.
- the ethanolamides which can be prepared from these fatty acids by reaction with diethanolamine are technical mixtures which usually contain 85 to 95% by weight of N-acyl compound and 2 to 10% by weight of O-acyl compound.
- These usual additions do not interfere in the present compositions, but can be regarded as functional constituents, especially since the compositions already contain soap and, in a preferred embodiment, also alkanolamines.
- the proportion of component (d) is 8 to 15% by weight, in particular up to 12% by weight.
- Suitable sequestering agents are polyaminopolyphosphonic acids and their mixtures with polycarboxylic acids.
- Suitable polycarboxylic acids are in particular citric acid, also nitrilotriacetic acid, ethylenediaminoetetraacetic acid and their higher homologues.
- Suitable polyaminopolyphosphonic acids are ethylenediaminetetra- (methylenephosphonic acid), diethylenetriaminepenta- (methylenephosphonic acid) and their higher homologues.
- the acids mentioned can be used as salts of sodium, potassium and alkanolamines, e.g. B. of triethanolamine.
- the particularly suitable ethylenediaminetetra- (methylenephosphonic acid) or diethylenetriaminepenta- (methylenephosphonic acid) are used in proportions of 0.2 to 2% by weight, preferably 0.4 to 1.2% by weight.
- the proportion of citric acid is preferably 0.3 to 1% by weight. Due to the moderately alkaline pH of the agent, the acids are in the form of acidic salts.
- the above-mentioned amounts refer to the amounts of acid to be used.
- Water-miscible solvents which are present in the compositions in proportions of 6 to 16% by weight, preferably 10 to 15% by weight, are alcohols, glycols, polyglycols and ether alcohols, such as methanol, ethanol, propanol, isopropanol, glycerol, Glycol, diethylene glycol, triethylene glycol and low molecular weight polyethylene glycols, propylene glycol and oligomeric propylene glycol ethers, furthermore ether alcohols, such as methyl propyl glycol, methyl butyl glycol or methyl ethyl glycol. Mixtures of ethanol and propanol in a ratio of 1: 4 to 4: 1 are preferably used as solvents.
- Additional ingredients which are advantageously added to the agents are enzymes, enzyme stabilizers, compounds for adjusting the pH, optical brighteners, hydrotropes, foam inhibitors, dyes or color pigments and agents which act as opacifiers or give the solutions a silky sheen.
- Suitable enzymes are proteases and amylases obtained from fungi or bacteria in a known manner and mixtures thereof, e.g. B. enzymes obtained from Bacillus subtilis or Bacillus licheniformis.
- the commercially available enzyme preparations usually also contain activators, such as calcium and magnesium salts, and extenders and binders. The content of the agents in these enzyme preparations is generally 0.1 to 1.5% by weight.
- the stability of the enzymes can be increased by adding alkanolamines, especially triethanolamine will.
- the triethanolamine is expediently present in excess, as a result of which a desired weakly alkaline reaction of 7.2 to 9, preferably 7.5 to 8.5, can be set.
- Low molecular weight acids such as formic acid, acetic acid and lactic acid are suitable as further enzyme stabilizers, which, based on free acid, can be present in proportions of 0.1 to 2, preferably 0.2 to 1,% by weight. Due to the basic reaction of the agents, these acids are predominantly or completely in the form of their salts, e.g. B. as sodium, potassium or alkanolamine salts.
- Examples of these are salts of 4,4-bis (-2 "-anilino-4" -morpholino-1,3,5-friazinyl-6 "-amino) -stilbene-2,2-disulfonic acid or of 4,4- Bis (2-sulfostyryl) diphenyl, 4,4-bis (4-chloro-3-sulfostyryl) diphenyl and 4- (4-chlorostyryl) -4- (2-sulfostyryl) diphenyl.
- Suitable foam inhibitors are water-dispersible silicones, e.g. B. dimethylpolysiloxanes, which can optionally be modified with polyglycol ether groups, and mixtures of such compounds with polysiloxane resins or finely divided silica, which is preferably silanated.
- the content of optical brighteners and silicone defoamers in the compositions can be of the order of 0.01 to 1% by weight.
- the water content of the agents should be adjusted so that a homogeneous, easily pourable solution that is not segregated by precipitation results.
- the water content is generally between 25 and 45% by weight, preferably between 33 and 40% by weight.
- the agents according to the invention have a high washing and cleaning ability, in particular with regard to bleachable soiling.
- Bleachable stains include, for example, stains from fruit and vegetable juices and tea infusions, the removal of which generally requires the use of oxidative bleaches.
- bleaching agents are not stable over a long period of time in liquid preparations. It is therefore highly surprising that the present compositions largely remove the soiling mentioned even in the absence of bleaching agents.
- the agents are characterized by favorable softening and grip-improving properties. They are suitable both for hand washing and due to their balanced foam behavior for use in washing machines.
- the coconut fatty acid consisted of 2% capric acid, 72% lauric acid and 26% myristic acid.
- Technical oleic acid consisted of 68% oleic acid, 6% palmitoleic acid and 15% linoleic acid. Their share in palmitic acid was 5% and in stearic acid 2%. The remaining 4% were saturated C12-14 fatty acids.
- the reflectance of the samples was determined photometrically and the washing power against the make-up stains and the handle (degree of softness) were assessed. The mean was formed from 9 measurements or samples.
- comparative samples were used which had been washed under similar conditions with a commercially available liquid detergent (V1) free of skeletal salts and bleaching agents or a commercially available high-performance detergent (V2) without further textile aftertreatment.
- V1 liquid detergent
- V2 high-performance detergent
- V3 commercially available high-performance detergent
- the grip properties were determined after 1 wash treatment and after 5 wash treatments.
- the handle assessments were carried out on terry towels washed once. The results are shown in the following tables. They demonstrate the superiority of the agents according to the invention.
- Grip rating 1 corresponds to the effect of a highly effective anti-aging agent used in the 4th rinse cycle on the basis of long-chain quaternary ammonium salts.

Abstract
Description
Die vorliegende Erfindung betrifft ein von Gerüstsalzen im wesentlichen freies, flüssiges Waschmittelkonzentrat, das aufgrund seiner Zusammensetzung trotz Abwesenheit oxidativer Bleichmittel eine verbesserte Waschwirkung gegenüber bleichbaren Anschmutzungen aufweist und in Verbindung mit speziell ausgewählten Fettsäurediethanolamiden textilweichmachende und griffverbessernde Eigenschaften besitzt, so daß die damit gewaschenen Textilien keiner Nachbehandlung mit einem speziellen Avivagemittel bedürfen.The present invention relates to a liquid detergent concentrate which is essentially free of skeletal salts and which, owing to its composition, has an improved washing action compared to bleachable stains despite the absence of oxidative bleaching agents and, in conjunction with specially selected fatty acid diethanolamides, has textile-softening and grip-improving properties, so that the textiles washed therewith have no post-treatment with a special finishing agent.
Das Problem, Flüssigwaschmittel zu entwickeln, die auch gegenüber bleichbaren Anschmutzungen, wie Obst-, Gemüse- oder Teeflecken, hinreichend wirksam sind, ist noch nicht hinreichend gelöst. Diese Anschmutzungen erfordern im allgemeinen die Anwendung oxidativ wirkender Bleichmittel, die sich wegen ihrer begrenzten Stabilität nicht oder nur schwierig in Flüssigwaschmittel inkorporieren lassen.The problem of developing liquid detergents that are also sufficiently effective against bleachable stains, such as fruit, vegetable or tea stains, has not yet been sufficiently solved. These stains generally require the use of oxidative bleaches which, owing to their limited stability, cannot be incorporated into liquid detergents, or can only be incorporated with difficulty.
Ein zweites Problem ist die Griffverbesserung der gewaschenen Textilien. Es ist aus der Zeitschrift "Soap and Chemical Specialities", November 1958, Seiten 48 bis 50, bekannt, daß gewisse Stearinsäurederivate von Alkylolaminen als weichmachendes Agens in Textilbehandlungsmitteln eingesetzt werden. Die Probleme, wie sich derartige Verbindungen in tensidhaltigen Waschmitteln verhalten bzw. eingesetzt werden können, werden in dieser Publikation nicht berührt. Im übrigen hat sich gezeigt, daß die Stearinsäurederivate sich nicht in wirksamer Menge in lagerstabile Flüssigwaschmittel einsetzen lassen.A second problem is the improvement in the grip of the washed textiles. It is known from the magazine "Soap and Chemical Specialties", November 1958, pages 48 to 50, that certain stearic acid derivatives of alkylolamines are used as softening agents in textile treatment agents. The problems of how such compounds behave or can be used in detergent-containing detergents are not dealt with in this publication. Furthermore, it has been shown that the stearic acid derivatives cannot be used in an effective amount in storage-stable liquid detergents.
Ferner sind zahlreiche Flüssigwaschmittel-Rezepturen bekannt, die mehr oder weniger große Gehalte an Fettsäuremono- bzw. diethanolamiden aufweisen. Stets handelt es sich dabei um solche Alkanolamide, die sich von Fettsäuregemischen mit hohem Anteil an C12-C16-Fettsäuren, beispielsweise Cocosfettsäuren, ableiten. Diese Alkanolamide sollen die Wasch- und Schaumkraft steigern bzw. die Hautverträglichkeit verbessern. Eine Avivagewirkung kommt diesen Mitteln nicht zu. Als Beispiele für derartige Mittel seien die gemäß DE-B-1 047 973, DE-C-2 022 064, DE-C-2 703 998 (US-A-4 153 570), DE-A-2 819 455, DE-C-3 022 767, DE-A-3 161 222, EP-A-38 101, US-A-2 861 956, US-A-2 943 058 aufgeführt.Furthermore, numerous liquid detergent formulations are known which have more or less large contents of fatty acid mono- or diethanolamides. These are always those alkanolamides which are derived from fatty acid mixtures with a high proportion of C12-C16 fatty acids, for example coconut fatty acids. These alkanolamides are said to increase washing and foaming power or to improve skin tolerance. These remedies do not have an aviva effect. Examples of such agents are those according to DE-B-1 047 973, DE-C-2 022 064, DE-C-2 703 998 (US-A-4 153 570), DE-A-2 819 455, DE -C-3 022 767, DE-A-3 161 222, EP-A-38 101, US-A-2 861 956, US-A-2 943 058.
Aus EP-A-157 320 ist ein Waschmittel bekannt, das anionische bzw. nichtionische Tenside sowie eine Kombination enthält, bestehend aus silikonhaltigen Schauminhibitoren und stickstoffhaltigen Verbindungen aus der Klasse der ethoxylierten Fettamine und Fettsäureethanolamide. Diese leiten sich bevorzugt von Cocosfettsäuren ab und wirken als Waschkraftverstärker. Eine Avivagewirkung besitzen sie nicht, außerdem ist ihr Anteil mit weniger als 5 Gew.-%, vorzugsweise weniger als 4 Gew.-%, vergleichsweise gering. Gemäß EP-A-151 678 enthalten flüssige Waschmittel 0 bis 5 Gew.-% eines "Cosurfactant", das aus oberflächenaktiven Quartärsalzen, tertiären Aminen oder Amioxiden besteht. Textilweichmachende Fettsäurediethanolamide werden in dem Dokument nicht erwähnt.EP-A-157 320 discloses a detergent which contains anionic or nonionic surfactants and a combination consisting of silicone-containing foam inhibitors and nitrogen-containing compounds from the class of ethoxylated fatty amines and fatty acid ethanolamides. These are preferably derived from coconut fatty acids and act as a detergency booster. They do not have an anti-sagging effect, and their proportion is comparatively low at less than 5% by weight, preferably less than 4% by weight. According to EP-A-151 678, liquid detergents contain 0 to 5% by weight of a "cosurfactant" consisting of surface-active quaternary salts, tertiary amines or amoxides. Textile softening fatty acid diethanolamides are not mentioned in the document.
Weiterhin wurde bereits vorgeschlagen, Waschmitteln mit einem Gehalt an Aniontensiden avivierend wirkende Quartärsalze zuzusetzen, wobei die Quartärsalze längerkettige Fettsäurereste bzw. Fettalkylreste aufweisen. Da jedoch Aniontenside mit derartigen Quartärsalzen im allgemeinen unverträglich sind bzw. unter Bildung inaktiver Elektroneutralsalze reagieren, wird die erwünschte Wirkung in der Regel nicht erzielt.Furthermore, it has already been proposed to add detergents containing quaternary salts with an anionic surfactant effect, the quaternary salts having longer-chain fatty acid residues or fatty alkyl residues. However, since anionic surfactants are generally incompatible with quaternary salts of this type or react to form inactive electroneutral salts, the desired effect is generally not achieved.
Das nachfolgend beschriebene erfindungsgemäße Mittel ist geeignet, die genannten Mängel zu vermeiden.The agent according to the invention described below is suitable for avoiding the deficiencies mentioned.

Der Anteil des linearen Natrium-alkylbenzolsulfonats (a) beträgt mindestens 6 Gew.-%, vorzugsweise bis 10 Gew.-%. Vorzugsweise wird Dodecylbenzolsulfonat eingesetzt.The proportion of the linear sodium alkylbenzenesulfonate (a) is at least 6% by weight, preferably up to 10% by weight.

Darüber hinaus können geringe Mengen, d. h. bis zu 5 Gew.-%, an nicht umgesetztem Ausgangsmaterial, hauptsächlich freies Diethanolamin sowie sehr geringe Mengen an freier Fettsäure anwesend sein. Diese üblichen Beimengungen stören in den vorliegenden Mitteln nicht, sondern können als funktionelle Bestandteile betrachtet werden, zumal die Mittel ohnehin Seife und in einer bevorzugten Ausführungsform auch Alkanolamine enthalten.The ethanolamides which can be prepared from these fatty acids by reaction with diethanolamine are technical mixtures which usually contain 85 to 95% by weight of N-acyl compound and 2 to 10% by weight of O-acyl compound. In addition, small amounts, i.e. H. up to 5% by weight of unreacted starting material, mainly free diethanolamine and very small amounts of free fatty acid. These usual additions do not interfere in the present compositions, but can be regarded as functional constituents, especially since the compositions already contain soap and, in a preferred embodiment, also alkanolamines.
Der Anteil der Komponente (d) beträgt 8 bis 15 Gew.-%, insbesondere bis 12 Gew.-%.The proportion of component (d) is 8 to 15% by weight, in particular up to 12% by weight.

Aufgrund des mäßig alkalischen pH-Wertes des Mittels liegen die Säuren in Form saurer Salze vor. Die vorgenannten Mengenangaben beziehen sich auf die einzusetzenden Säuremengen.Suitable sequestering agents (e) are polyaminopolyphosphonic acids and their mixtures with polycarboxylic acids. Suitable polycarboxylic acids are in particular citric acid, also nitrilotriacetic acid, ethylenediaminoetetraacetic acid and their higher homologues. Suitable polyaminopolyphosphonic acids are ethylenediaminetetra- (methylenephosphonic acid), diethylenetriaminepenta- (methylenephosphonic acid) and their higher homologues. The acids mentioned can be used as salts of sodium, potassium and alkanolamines, e.g. B. of triethanolamine. The particularly suitable ethylenediaminetetra- (methylenephosphonic acid) or diethylenetriaminepenta- (methylenephosphonic acid) are used in proportions of 0.2 to 2% by weight, preferably 0.4 to 1.2% by weight. The proportion of citric acid is preferably 0.3 to 1% by weight. Due to the moderately alkaline pH of the agent, the acids are in the form of acidic salts. The above-mentioned amounts refer to the amounts of acid to be used.
Mit Wasser mischbare Lösungsmittel, die in den Mitteln in Anteilen von 6 bis 16 Gew.-%, vorzugsweise 10 bis 15 Gew.-% vorliegen, sind Alkohole, Glykole, Polyglykole und Etheralkohole, wie Methanol, Ethanol, Propanol, Isopropanol, Glycerin, Glykol, Diethylenglykol, Triethylenglykol und niedermolekulare Polyethylenglykole, Propylenglykol und oligomere Propylenglykolether, ferner Etheralkohole, wie Methylpropylglykol, Methylbutylglykol oder Methylethylglykol.

Als Enzyme eignen sich aus Pilzen oder Bakterien in bekannter Weise gewonnene Proteasen und Amylasen sowie deren Gemische, z. B. aus Bacillus subtilis oder Bacillus licheniformis gewonnene Enzyme. Die handelsüblichen Enzymzubereitungen enthalten in der Regel noch Aktivatoren, wie Calcium-und Magnesiumsalze, sowie Streck- und Bindemittel. Der Gehalt der Mittel an diesen Enzymzubereitungen beträgt im allgemeinen 0,1 bis 1,5 Gew.-%.Suitable enzymes are proteases and amylases obtained from fungi or bacteria in a known manner and mixtures thereof, e.g. B. enzymes obtained from Bacillus subtilis or Bacillus licheniformis. The commercially available enzyme preparations usually also contain activators, such as calcium and magnesium salts, and extenders and binders. The content of the agents in these enzyme preparations is generally 0.1 to 1.5% by weight.
Die Stabilität der Enzyme kann durch Zusatz von Alkanolaminen, insbesondere Triethanolamin, erhöht werden. Das Triethanolamin ist zweckmäßigerweise im Überschuß vorhanden, wodurch sich eine gewünschte schwach alkalische Reaktion von 7,2 bis 9, vorzugsweise von 7,5 bis 8,5 einstellen läßt.The stability of the enzymes can be increased by adding alkanolamines, especially triethanolamine will. The triethanolamine is expediently present in excess, as a result of which a desired weakly alkaline reaction of 7.2 to 9, preferably 7.5 to 8.5, can be set.
Als weitere Enzymstabilisatoren eignen sich niedermolekulare Säuren wie Ameisensäure, Essigsäure und Milchsäure, die, auf freie Säure bezogen, in Anteilen von 0,1 bis 2, vorzugsweise 0,2 bis 1 Gew.-% anwesend sein können. Aufgrund der basischen Reaktion der Mittel liegen diese Säuren überwiegend oder vollständig in Form ihrer Salze vor, z. B. als Natrium-, Kalium- oder Alkanolaminsalze.Low molecular weight acids such as formic acid, acetic acid and lactic acid are suitable as further enzyme stabilizers, which, based on free acid, can be present in proportions of 0.1 to 2, preferably 0.2 to 1,% by weight. Due to the basic reaction of the agents, these acids are predominantly or completely in the form of their salts, e.g. B. as sodium, potassium or alkanolamine salts.
Als optische Aufheller eignen sich die bekannten Derivate der Bis-triazinyl-4,4'-diaminostilben-2,2'- disulfonsäure bzw. der Diphenyl-distyryl-disulfonsäure in Form ihrer wasserlöslichen Salze. Beispiele hierfür sind Salze der 4,4-Bis(-2"-anilino-4"-morpholino-1,3,5-friazinyl-6"-amino)-stilben-2,2-disulfonsäure bzw. des 4,4-Bis-(2-sulfostyryl)-diphenyls, 4,4-Bis(4-chlor-3-sulfostyryl)-diphenyls und 4-(4-Chlorstyryl)-4-(2-sulfostyryl)-diphenyls.The known derivatives of bis-triazinyl-4,4'-diaminostilbene-2,2'-disulfonic acid or diphenyl-distyryl-disulfonic acid in the form of their water-soluble salts are suitable as optical brighteners. Examples of these are salts of 4,4-bis (-2 "-anilino-4" -morpholino-1,3,5-friazinyl-6 "-amino) -stilbene-2,2-disulfonic acid or of 4,4- Bis (2-sulfostyryl) diphenyl, 4,4-bis (4-chloro-3-sulfostyryl) diphenyl and 4- (4-chlorostyryl) -4- (2-sulfostyryl) diphenyl.
Als Schauminhibitoren eignen sich in Wasser dispergierbare Silikone, z. B. Dimethylpolysiloxane, die gegebenenfalls mit Polyglykolethergruppen modifiziert sein können, sowie Gemische derartiger Verbindungen mit Polysiloxanharzen bzw. feinteiliger Kieselsäure, die vorzugsweise silaniert ist. Der Gehalt der Mittel an optischen Aufhellern und Silikonentschäumern kann in der Größenordnung 0,01 bis 1 Gew.-% liegen.Suitable foam inhibitors are water-dispersible silicones, e.g. B. dimethylpolysiloxanes, which can optionally be modified with polyglycol ether groups, and mixtures of such compounds with polysiloxane resins or finely divided silica, which is preferably silanated. The content of optical brighteners and silicone defoamers in the compositions can be of the order of 0.01 to 1% by weight.
Der Wassergehalt der Mittel soll so eingestellt sein, daß eine homogene, gut gießbare und nicht durch Ausfällungen entmischte Lösung entsteht. Der Wassergehalt liegt im allgemeinen zwischen 25 und 45 Gew.-%, vorzugsweise zwischen 33 und 40 Gew.-%.The water content of the agents should be adjusted so that a homogeneous, easily pourable solution that is not segregated by precipitation results. The water content is generally between 25 and 45% by weight, preferably between 33 and 40% by weight.
Die erfindungsgemäßen Mittel besitzen ein hohes Wasch- und Reinigungsvermögen, insbesondere gegenüber bleichbaren Anschmutzungen. Zu den bleichbaren Anschmutzungen zählen beispielsweise Flecken von Obst- und Gemüsesäften sowie von Teeaufgüssen, zu deren Entfernung im allgemeinen die Anwendung oxidativer Bleichmittel erforderlich ist. Derartige Bleichmittel sind aber in flüssigen Zubereitungen nicht über längere Zeit stabil. Es ist daher in hohem Maße überraschend, daß die vorliegenden Mittel auch in Abwesenheit von Bleichmitteln die genannten Anschmutzungen weitgehend entfernen. Weiterhin zeichnen sich die Mittel durch günstige weichmachende und griffverbessernde Eigenschaften aus. Sie eignen sich sowohl für ein Waschen von Hand als auch aufgrund ihres ausgewogenen Schaumverhaltens zur Anwendung in Waschmaschinen.The agents according to the invention have a high washing and cleaning ability, in particular with regard to bleachable soiling. Bleachable stains include, for example, stains from fruit and vegetable juices and tea infusions, the removal of which generally requires the use of oxidative bleaches. However, such bleaching agents are not stable over a long period of time in liquid preparations. It is therefore highly surprising that the present compositions largely remove the soiling mentioned even in the absence of bleaching agents. Furthermore, the agents are characterized by favorable softening and grip-improving properties. They are suitable both for hand washing and due to their balanced foam behavior for use in washing machines.
Zur Herstellung eines Mittels gemäß nachstehender Zusammensetzung wurde eine 50% wäßrige paste von Natrium-dodecylbenzolsulfonat mit dem nichtionischen Tensid (Abkürzung EO = angelagertes Ethylenoxid) vermischt, anschließend das Lösungsmittel, das Fettsäurediethanolamid und die zur Seifenbildung benötigte Fettsäure sowie die Phosphonsäure (Diethylentriaminpentamethylenphosphonsäure) und die Citronensäure zugemischt. Nach der Neutralisation mit Natronlauge und Triethanolamin erfolgte der Zusatz der übrigen Stoffe (Angaben in Gew.-%, bezogen auf wasserfreie Substanz).
Die Cocosfettsäure bestand zu 2% aus Caprinsäure, zu 72% aus Laurinsäure und zu 26% aus Myristinsäure. Die technische Ölsäure bestand zu 68% aus Ölsäure, zu 6% aus Palmitoleinsäyre und zu 15% aus Linolsäure. Ihr Anteil an Palmitinsäure betrug 5% und an Stearinsäure 2%. Die restlichen 4% entfielen auf gesättigte C12-14-Fettsäuren.The coconut fatty acid consisted of 2% capric acid, 72% lauric acid and 26% myristic acid. Technical oleic acid consisted of 68% oleic acid, 6% palmitoleic acid and 15% linoleic acid. Their share in palmitic acid was 5% and in stearic acid 2%. The remaining 4% were saturated C12-14 fatty acids.
Das Waschvermögen und die Avivagewirkung wurden unter praxisnahen Bedingungen getestet. Hierzu wurden Textilproben aus Baumwolle, die unter standardisierten Bedingungen mit Hautfett, Pigmentschmutz, Make-up-Flecken (Lippenstift, Wimperntusche, getönte Hautcreme) und Flecken von Rotwein, Tee und Blaubeeren angeschmutzt worden waren, zusammen mit 3 kg Ballastwäsche in einem Haushaltswaschautomaten (Kapazität 4 kg) bei 60°C gewaschen. Die Waschdauer einschließlich Aufheizung betrug 20 Minuten, die Waschmittelkonzentration 7,5 g/Liter, das Verhältnis von Textilmenge (in kg) zu Waschlauge (in Liter) betrug 1 : 10, die Härte des Leitungswassers 16°dH (160 mg CaO pro Liter). Nach dreimaligem Nachspülen wurde geschleudert und getrocknet. Die Remission der Proben wurde photometrisch bestimmt und die Waschkraft gegenüber den Make-up-Anschmutzungen sowie der Griff (Weichheitsgrad) beurteilt. Aus jeweils 9 Messungen bzw. Abmusterungen wurde der Mittelwert gebildet. Bei der Beurteilung der weichmachenden Eigenschaften wurden Vergleichsproben herangezogen, die unter gleichartigen Bedingungen mit einem handelsüblichen, von Gerüstsalzen und Bleichmitteln freien Flüssigwaschmittel (V1) bzw. einem handelsüblichen Hochleistungswaschmittel (V2) ohne weitere Textilnachbehandlung gewaschen worden waren. In einer dritten Versuchsreihe wurden Proben zum Vergleich herangezogen, die mit einem handelsüblichen Hochleistungswaschmittel (V3) gewaschen wurden, das einen avivierend wirkenden Zusatz auf Basis eines Cocosalkyl-trimethylammoniumsalzes enthielt. Die Bestimmung der Griffeigenschaften wurden nach 1 Waschbehandlung sowie nach 5 Waschbehandlungen vorgenommen. Zusätzlich wurden die Griffbeurteilungen an 1 mal gewaschener Frottierware vorgenommen. Die Ergebnisse sind den folgenden Tabellen zu entnehmen. Sie belegen die Überlegenheit der erfindungsgemäßen Mittel.
Bei der Remissionsmessung entspricht ein höherer Wert einem besseren Waschergebnis. Bei der Benotung entspricht 1 (sehr gut) dem besten, 6 (ungenügend) dem schlechtesten Wert. Die GriffBenotung 1 entspricht der Wirkung eines im 4. Spülgang eingesetzten hochwirksamen Avivagemittels auf der Basis langkettiger quartärer Ammoniumsalze.In the remission measurement, a higher value corresponds to a better washing result. In the grading, 1 (very good) corresponds to the best, 6 (insufficient) to the worst. Grip rating 1 corresponds to the effect of a highly effective anti-aging agent used in the 4th rinse cycle on the basis of long-chain quaternary ammonium salts.
