Da der erfindungsgemässe Waschrohstoff gleichzeitig die Komponenten LAS, nichtionogenes Tensid, Entschäumer, Komplexbildner und Fettalkoholsulfat ersetzt, erleichtert die Verwendung von nur einer Komponenten die Dosierung in der Waschmittelzusammensetzung und führt zu einer Vereinfachung des Waschpulver-Herstellungsverfahrens.Since the detergent raw material according to the invention simultaneously replaces the components LAS, nonionic surfactant, defoamer, complexing agent and fatty alcohol sulfate, the use of only one component facilitates the metering in the detergent composition and leads to a simplification of the detergent powder production process.
Durch den Einsatz verschiedener nichtionogener Tenside der Formel (1), (2) oder (3) bei der Herstellung des erfindungsgemässen Waschrohstoffs kann eine weitere Variabilität des Waschmittels bezüglich seiner Eigenschaften erreicht werden. So kann z.B. das Netzvermögen, die Waschwirkung oder das Schaumverhalten durch die Verwendung entsprechender nichtionogener Tenside eingestellt werden. Die Komplexierwirkung und die Waschwirkung sind über die Menge der eingesetzten ethylenisch ungesättigten Sulfonsäuren oder Carbonsäuren steuerbar. Die Zucker-Acrylsäurepolymerisate sind bekannte, biologisch sehr gut abbaubare Komplexbildner und erlauben daher ebenfalls eine Einstellung des Calcium-Dispergiervermögens.Through the use of various nonionic surfactants of the formula (1), (2) or (3) in the production of the detergent raw material according to the invention, a further variability of the properties of the detergent can be achieved. For example, the wetting capacity, the washing effect or the foaming behavior can be adjusted by using appropriate non-ionic surfactants. The complexing action and the washing action can be controlled via the amount of the ethylenically unsaturated sulfonic acids or carboxylic acids used. The sugar-acrylic acid polymers are known, highly biodegradable complexing agents and therefore also allow the calcium dispersing capacity to be adjusted.

The active wash raw material content is 5 to 35% by weight.
Beispiel 16: Alle in Beispiel 12 erwähnten festen Komponenten des Sprüh-Slurrys werden einem Misch- und Mahl-Prozess, z.B. in einem Pfugschar-Mischer und/oder einem Wirbelschichtaggregat unterzogen. Das resultierende Pulvermaterial wird mit dem Waschrohstoff, sowie mit Parfümöl aufgesprüht, so dass kompakte Granulate mit hohem Schüttgewicht erhalten werden. Im Wirbelschicht- oder Pflugscharmischer werden schliesslich Perborat/Tetra-oder vorzugsweise Monohydrat oder Percarbonat, sowie ein Aktivator wie TAED, NOBS sowie gegebenenfalls ein Schutzsilikat zugemischt. Es wird ein stabiles, nicht-klebriges Kompaktwaschmittel erhalten. Example 16: All solid components of the spray slurry mentioned in Example 12 are subjected to a mixing and grinding process, for example in a ploughshare mixer and / or a fluidized bed unit. The resulting powder material is sprayed with the wash raw material and with perfume oil, so that compact granules with a high bulk density are obtained. Finally, perborate / tetra or preferably monohydrate or percarbonate, and an activator such as TAED, NOBS and optionally a protective silicate are mixed in the fluidized bed or ploughshare mixer. A stable, non-sticky, compact detergent is obtained.

The difference ΔY before and after washing is a measure of the removal of dirt.
In Tabelle 1a und 1b sind die Waschergebnisse aufgeführt.
Die Ergebnisse aus den Tabellen 1a und 1b zeigen, dass mit den erfindungsgemässen Waschrohstoffen sehr gute Waschergebnisse erzielt werden.The results from Tables 1a and 1b show that very good washing results are achieved with the washing raw materials according to the invention.
Beispiele 21 bis 23: In der Regel enthalten Waschmittel sogenannte "Anti-Redeposition-Agents", meistens Carboxymethylcellulose (CMC) und/oder Polyacrylsäure, wobei auch Na-Triphosphate eine solche Schmutztragewirkung besitzt. Examples 21 to 23: As a rule, detergents contain so-called “anti-redeposition agents”, mostly carboxymethyl cellulose (CMC) and / or polyacrylic acid, Na triphosphates also having such a dirt-carrying effect.
Die Anti-Redeposition-Eigenschaften werden wie folgt getestet: 5 g gebleichtes Baumwoll-Testgewebe werden in 100 ml deionisiertem Wasser mit einem pH-Wert von 10,5 (eingestellt mit NaOH) während 20 Minuten bei 60°C gewaschen, wobei dem Waschbad 40 mg von definierten Russarten zugesetzt werden. Dann wird mit Leitungswasser kurz gespült und bei 60°C getrocknet.The anti-redeposition properties are tested as follows: 5 g of bleached cotton test fabric are washed in 100 ml of deionized water with a pH of 10.5 (adjusted with NaOH) for 20 minutes at 60 ° C., whereby 40 mg of defined soot types are added to the wash bath. Then it is rinsed briefly with tap water and dried at 60 ° C.
Es werden je 0,5 g/l der aktiven Waschrohstoffe aus den Beispielen 5, 6 und 7 getestet. Jeder Versuch wird doppelt durchgeführt, wobei an 8 verschiedenen Stellen des Textilstücks spektrophotometrisch der Helligkeitswert Y gemessen, sowie der Durchschnittswert (=⌀) der 16 Messwerte und die Standardabweichung (=σ) berechnet werden. Beim unbehandelten Baumwollmaterial ist Y=93,0 (σ=0,1). Die Abnahme der Helligkeit ist ein Mass für die "Deposition". Je effektiver die Anti-Redeposition-Wirkung eines Systems ist, desto geringer ist diese Abnahme, d.h. desto höher ist die Y-Zahl.0.5 g / l of the active wash raw materials from Examples 5, 6 and 7 are tested in each case. Each test is carried out twice, with the brightness value Y being measured spectrophotometrically at 8 different points on the textile piece, the average value (= ⌀) of the 16 measured values and the standard deviation (= σ) being calculated. For the untreated cotton material, Y = 93.0 (σ = 0.1). The decrease in brightness is a measure of the "deposition". The more effective the anti-redeposition effect of a system, the less this decrease, i.e. the higher the Y number.
Die Versuche werden mit folgenden Russ-Arten durchgeführt:
- a) ®Cabot SRF N762 der Firma Cabot (Iodadsorption 30 mg/g; DBP-Absorption = 65 ml/100 g; Siebrückstand = 325 mesh = 500 ppm, Schüttdichte = 505 g/dm3).
- b) ®Carax N 765 der Firma Degussa (Iodadsorption = 34 mg/g; DBP-Absorption = 122 ml/100 g; Siebrückstand 325 mesh = 500 ppm, Schüttdichte = 375 g/dm3.
- a) ®Cabot SRF N762 from Cabot (iodine adsorption 30 mg / g; DBP absorption = 65 ml / 100 g; sieve residue = 325 mesh = 500 ppm, bulk density = 505 g / dm 3 ).
- b) ®Carax N 765 from Degussa (iodine adsorption = 34 mg / g; DBP absorption = 122 ml / 100 g; sieve residue 325 mesh = 500 ppm, bulk density = 375 g / dm 3 .
Die Waschergebnisse sind in Tabelle 2 aufgeführt.
Die Ergebnisse zeigen, dass die erfindungsgemässen Waschrohstoffe sehr gute Redeposition-Eigenschaften aufweisen und die sonst handelsüblichen Redeposition-Mittel ersetzen können.The results show that the washing raw materials according to the invention have very good redeposition properties and can replace the otherwise commercially available redeposition agents.
Beispiele 24 bis 26: Es werden Tensid-Lösungen a) bis c) vorbereitet, die jeweils 2,0 g/l des aus den Beispielen 5, 6 bzw. 7 erhältlichen Waschrohstoffs enthalten. Insgesamt werden also 9 Lösungen hergestellt. Examples 24 to 26: Surfactant solutions a) to c) are prepared, each containing 2.0 g / l of the wash raw material obtainable from Examples 5, 6 and 7. In total, 9 solutions are produced.
Die Tensid-Lösungen a) bis c) werden folgendermaßen hergestellt:
- a) mit deionisiertem Wasser,
- b) mit deionisiertem Wasser und Zugabe von 5 g Olivenöl auf 50 ml Lösung,
- c) Einstellung der Wasserhärte auf 15°dH durch Zugabe der entsprechenden Menge von
- CaCl2-und MgSO4-Lösungen gemäss DIN 53905
- a) with deionized water,
- b) with deionized water and adding 5 g of olive oil to 50 ml of solution,
- c) Setting the water hardness to 15 ° dH by adding the appropriate amount of
- CaCl 2 and MgSO 4 solutions according to DIN 53905
In einem Zylinderglas von 4 cm Durchmesser und 40 cm Höhe wird bei Raumtemperatur 50 ml der Tensid-Lösung eingefüllt und das Glas mit einem Zapfen verschlossen. Danach wird das Glas 10x von Hand auf den Kopf und wieder zurückgestellt. Die Schaumhöhe wird sofort, danach in Abständen von 30 Sekunden bis 10 Minuten gemessen.50 ml of the surfactant solution are poured into a cylindrical glass 4 cm in diameter and 40 cm high at room temperature and the glass is closed with a plug. Then the glass is turned upside down 10 times by hand and back again. The foam height is measured immediately, then at intervals of 30 seconds to 10 minutes.
Die Ergebnisse sind in Tabelle 3 dargestellt.
Die Ergebnisse zeigen, dass die erfindungsgemässen Waschrohstoffe selbst unter Belastung durch Öl oder Wasserhärte das von den Waschmittel-Herstellern gewünschte Schaumverhalten aufweisen, d.h. dass zu Beginn des Waschvorgangs etwas Schaum gebildet wird, der während des gesamten Waschprozesses einerseits bestehen bleibt, aber andererseits nicht ausgeprägt ist, um ein Überfliessen aus der Waschmaschine zu verhindern.The results show that the washing raw materials according to the invention have the foaming behavior desired by the detergent manufacturers even when exposed to oil or water hardness, i.e. that at the beginning of the washing process some foam is formed which remains on the one hand during the entire washing process but on the other hand is not pronounced in order to prevent it from overflowing out of the washing machine.
