Definitions
- the invention relates to a detergent with 5 to 50% by weight, preferably 10 to 30% by weight, at least one surfactant, 0.5 to 60% by weight, preferably 5 to 60% by weight, builders and customary washing auxiliaries.
- silicate detergent builders so-called builders, e.g. Zeolite A and / or crystalline layered sodium silicate in combination with organic polycarboxylic acids, e.g. Citric acid or its salts is known from EP-0 405 122 A2. It is desirable that such polycarboxylic acids increase the washing performance of the detergents provided with them and are largely harmless from an ecological point of view, i.e. are readily biodegradable. This requirement also includes a pronounced lime binding capacity that should be preserved as far as possible over a temperature range of 20 to 90 ° C, as is common in household laundry.
- polyglycol diacid (CAS No. 39927-08-7) fulfills these requirements in the broadest sense.
- the lime binding capacity of polyglycol diacid is 220 mg Ca / g, at 60 and 90 ° C it is still 80 mg Ca / g, while citric acid only contains lime binders of 195 mg Ca / g at room temperature and 30 mg Ca / g at 90 ° C owns.
- the detergent of the invention is now characterized in that it contains 3 to 11% by weight of polyglycol diacid in addition to other builders.
- Detergent formulations which, in addition to crystalline layered sodium silicate and / or zeolite A, contain polyglycol diacid in concentrations of 3 to 10% by weight, mostly provide very good washing performance both with regard to dirt removal and with regard to preventing tissue deposits.
- the detergents were produced by the spray mixing method.
- a free-fall mixer was used in which the solid powdery components were premixed.
- the liquid ingredients were then sprayed onto the dry premix. The procedure is described in detail in the magazine "Seifen, Fette, ⁇ le, Wwachs” 99 (1973), pp. 351-357.
- test formulations given in Table 1 (Examples 1 to 12), including a commercial detergent, were tested under washing conditions in accordance with the following conditions:
- Table 2 shows the washing results obtained with Examples 1-12.
- the individual results which were measured on the test fabrics BW 101 (EMPA) and PE / BW 20C (WFK) are shown.
- the secondary washing effect is shown in the form of the average ash values (average of 5 test fabrics).
- Examples 2-4 and 8-11 according to the invention are superior in all respects to Comparative Examples 1 and 5 (without polyglycol diacid). But also in comparison with the commercial detergent concentrate No. 12, the examples 2-4 and 8-11 according to the invention show a clearly better washing performance.
- Examples 6 and 7 represent borderline cases which show that zeolite A generally does not show the good washing action as SKS 6, which is why without SKS 6 more than 6% by weight polyglycol diacid should be present in the detergent.
- Nonionic surfactants are understood to mean those compounds which have an organic, hydrophobic group and a hydrophilic radical, for example the condensation products of alkylphenols or higher fatty alcohols with ethylene oxide (fatty alcohol ethoxylates), the condensation products of polypropylene glycol with ethylene oxide or propylene oxide, the condensation products of Ethylene oxide with the reaction product of ethylenediamine and propylene oxide, as well as long-chain tertiary amine oxides

- the organic complexing agents include, for example, nitrilotriacetic acid, ethylenediaminetetraacetic acid, N-hydroxyethylethylenediaminetriacetic acid or polyalkylene-polyamine-N-polycarboxylic acids.
- Washing aids according to the invention also include products such as the alkali or ammonium salts of sulfuric acid, boric acid, alkylene, hydroxyalkylene or aminoalkylenephosphonic acid, as well as bleaching agents, stabilizers for peroxide compounds (bleaching agents) and water-soluble organic complexing agents.

Abstract
Description
Die Erfindung betrifft ein Waschmittel mit 5 bis 50 Gew%, vorzugsweise 10 bis 30 Gew%, mindestens eines Tensids, 0,5 bis 60 Gew%, vorzugsweise 5 bis 60 Gew%, Gerüststoffen sowie üblichen Waschhilfsstoffen.The invention relates to a detergent with 5 to 50% by weight, preferably 10 to 30% by weight, at least one surfactant, 0.5 to 60% by weight, preferably 5 to 60% by weight, builders and customary washing auxiliaries.
Die Verwendung silikatischer Waschmittel-Gerüststoffe, sog. Builder, wie z.B. Zeolith A und/oder kristallines Natriumschichtsilikat in Kombination mit organischen Polycarbonsäuren, z.B. Citronensäure oder deren Salzen, ist aus der EP-0 405 122 A2 bekannt. Erwünscht ist, daß derartige Polycarbonsäuren die Waschleistung der damit ausgestatteten Waschmittel erhöhen und in ökologischer Hinsicht weitgehend unbedenklich, d.h. biologisch gut abbaubar sind. Diese Forderung umfaßt auch ein ausgeprägtes Kalkbindevermögen, das über einen Temperaturbereich von 20 bis 90°C, wie er bei der Haushaltswäsche üblich ist, soweit wie möglich erhalten bleiben soll.The use of silicate detergent builders, so-called builders, e.g. Zeolite A and / or crystalline layered sodium silicate in combination with organic polycarboxylic acids, e.g. Citric acid or its salts is known from EP-0 405 122 A2. It is desirable that such polycarboxylic acids increase the washing performance of the detergents provided with them and are largely harmless from an ecological point of view, i.e. are readily biodegradable. This requirement also includes a pronounced lime binding capacity that should be preserved as far as possible over a temperature range of 20 to 90 ° C, as is common in household laundry.
Wie nun überraschenderweise gefunden wurde, erfüllt die sogenannte Polyglykoldisäure (CAS-Nr. 39927-08-7) im weitesten Sinne diese Anforderungen. Bei Raumtemperatur beträgt das Kalkbindevermögen von Polyglykoldisäure 220 mg Ca/g, bei 60 und 90°C immerhin noch 80 mg Ca/g, während die Citronensäure nur Kalkbindewerte von 195 mg Ca/g bei Raumtemperatur und 30 mg Ca/g bei 90°C besitzt.As has now surprisingly been found, the so-called polyglycol diacid (CAS No. 39927-08-7) fulfills these requirements in the broadest sense. At room temperature the lime binding capacity of polyglycol diacid is 220 mg Ca / g, at 60 and 90 ° C it is still 80 mg Ca / g, while citric acid only contains lime binders of 195 mg Ca / g at room temperature and 30 mg Ca / g at 90 ° C owns.
Im einzelnen ist das Waschmittel der Erfindung nunmehr dadurch gekennzeichnet, daß es neben anderen Gerüststoffen 3 bis 11 Gew% Polyglykoldisäure enthält.In particular, the detergent of the invention is now characterized in that it contains 3 to 11% by weight of polyglycol diacid in addition to other builders.
Darüber hinaus kann das Waschmittel der Erfindung wahlweise oder bevorzugt dadurch gekennzeichnet sein, daß es
- a) neben kristallinem Natrium-Schichtsilikat 3 bis 10 Gew% Polyglykoldisäure enthält;
- b) neben Zeolith A 7 bis 10 Gew% Polyglykoldisäure enthält;
- c) neben kristallinem Natrium-Schichtsilikat und Zeolith A 5 bis 10 Gew% Polyglykoldisäure enthält.
- a) contains 3 to 10% by weight of polyglycol diacid in addition to crystalline layered sodium silicate;
- b) in addition to zeolite A contains 7 to 10% by weight of polyglycol diacid;
- c) in addition to crystalline layered sodium silicate and zeolite A contains 5 to 10% by weight of polyglycol diacid.
Waschmittelformulierungen, die neben kristallinem Na-Schichtsilikat und/oder Zeolith A Polyglykoldisäure in Konzentrationen von 3 bis 10 Gew% enthalten, liefern überwiegend sehr gute Waschleistungen sowohl bezüglich der Schmutzentfernung als auch bezüglich der Verhinderung von Gewebeablagerungen.Detergent formulations which, in addition to crystalline layered sodium silicate and / or zeolite A, contain polyglycol diacid in concentrations of 3 to 10% by weight, mostly provide very good washing performance both with regard to dirt removal and with regard to preventing tissue deposits.

In Tabelle 2 sind die mit den Beispielen 1 - 12 erhaltenen Waschergebnisse zusammengestellt. Bei der Primärwaschwirkung sind die jeweiligen Einzelergebnisse, die an den Testgeweben BW 101 (EMPA) und PE/BW 20C (WFK) gemessen wurden, wiedergegeben. Die Sekundärwaschwirkung ist in Form der durchschnittlichen Aschewerte (Mittel aus 5 Testgeweben) aufgeführt. Wie ersichtlich sind die erfindungsgemäßen Beispiele 2 - 4 und 8 - 11 den Vergleichsbeispielen 1 und 5 (ohne Polyglykoldisäure) in jeder Hinsicht überlegen. Aber auch im Vergleich mit dem kommerziellen Waschmittelkonzentrat Nr. 12 zeigen die erfindungsgemäßen Beispiele 2 - 4 und 8 - 11 eine eindeutig bessere Waschleistung. Die Beispiele 6 und 7 stellen Grenzfälle dar, die zeigen, daß Zeolith A im allgemeinen nicht die gute Waschwirkung zeigt, wie SKS 6, weshalb ohne SKS 6 mehr als 6 Gew% Polyglykoldisäure im Waschmittel vorhanden sein sollten.
