Description

Es sind eine Reihe von optischen Aufhellern bekannt, die aufgrund ihrer Oxidationsbeständigkeit in aktivchlorhaltigen Bleich- und Waschmitteln eingesetzt werden können. Zu diesen zählen insbesondere Aufheller aus der Verbindungsklasse der 4,4'-Bis-(styryl)-diphenyle und der Benztriazolylstilbene. Es hat sich jedoch gezeigt, daß viele dieser Aufheller in Gegenwart von Persäuren entweder nicht bzw. nur mäßig beständig oder ungenügend brillant sind. Andererseits weisen peroxysäurehaltige Bleichmittel gegenüber aktivchlorhaltigen Mitteln eine Reihe anwendungstechnischer Vorteile, insbesondere größere Lagerstabilität und Fehlen jedweder Geruchsbelästigung auf. Persalze, insbesondere Perborat,enthaltenden Mitteln sind sie aufgrund ihrer höheren Bleichkraft, insbesondere bei Temperaturen zwischen 30 und 70 °C, überlegen. Es wurde nun eine Kombination aufgefunden, welche die Vorteile eines Persäurebleichmittels mit denen eines speziellen, gegen Peroxysäuren beständigen Aufhellers mit hoher Brillanz vorteilhaft vereinigt.A number of optical brighteners are known which, owing to their oxidation resistance, can be used in bleaching agents and detergents containing active chlorine. These include in particular brighteners from the class of 4,4'-bis (styryl) diphenyls and the benzotriazolylstilbene. However, it has been shown that many of these brighteners are either not or only moderately stable or insufficiently brilliant in the presence of peracids. On the other hand, peroxyacid-containing bleaching agents have a number of application-related advantages over agents containing active chlorine, in particular greater storage stability and the absence of any odor nuisance. Persal salts, especially perborate, are superior to agents because of their higher bleaching power, especially at temperatures between 30 and 70 ° C. A combination has now been found which advantageously combines the advantages of a peracid bleach with those of a special brightener which is resistant to peroxyacids and has a high brilliance.

Die bleichmittelhaltigen Waschmittel der genannten Zusammensetzung können als fertige, vorzugsweise pulverförmige bis körnige Gemische vorliegen und als solche zur Anwendung kommen. In diesem Fall kann es zweckmäßig sein, die Peroxysäuren mit einem Hüllmaterial, beispielsweise wasserlöslichen Polymeren, bei der Anwendungstemperatur schmelzenden Wachsen oder seifenbildenden Fettsäuren bzw. wachsartigen nichtionischen Waschaktivsubstanzen zu versehen, um einer möglichen Zersetzung während der Lagerung entgegenzuwirken. Die Gemische aus Peroxysäuren und optischen Aufhellern können jedoch auch getrennt von den übrigen Bestandteilen aufbewahrt und beispielsweise in Portionsbeuteln abgefüllt bzw. in Tablettenform überführt werden. Die Vereinigung mit den übrigen Waschmittelbestandteilen erfolgt dann unmittelbar vor der Anwendung bzw. in der Waschflotte.The bleach-containing detergents of the composition mentioned can be present as finished, preferably powdery to granular, mixtures and can be used as such. In this case, it may be expedient to provide the peroxyacids with a coating material, for example water-soluble polymers, waxes melting at the application temperature or soap-forming fatty acids or wax-like nonionic detergent substances in order to counteract possible decomposition during storage. However, the mixtures of peroxyacids and optical brighteners can also be stored separately from the other constituents and for example be filled in sachets or transferred into tablets. The combination with the other detergent components then takes place immediately before use or in the washing liquor.

Bei der Anwendung,werden die Mittel zweckmäßigerweise so dosiert, daß die Konzentration an Aktivsauerstoff in der Bleich- bzw. Waschlauge 5 bis 250 ppm und die des erfindungsgemäß zu verwendenden Aufhellers bzw. Aufhellergemisches 1 bis 150 ppm beträgt. Soweit das Bleichmittel zusammen mit einem Waschmittelgemisch eingesetzt wird, beträgt dessen Konzentration - je nach Anwendungsgebiet - einschließlich der Bleichmittelkomponente 2 bis 10 g/l, vorzugsweise 3 bis 8 g/l. Die Anwendungstemperatur kann 25 bis 100 °C betragen, vorzugsweise liegt sie jedoch in dem Bereich zwischen 40 und 70 °C.When used, the agents are expediently metered in such a way that the concentration of active oxygen in the bleaching or washing liquor is 5 to 250 ppm and that of the brightener or brightener mixture to be used according to the invention is 1 to 150 ppm. If the bleaching agent is used together with a detergent mixture, its concentration - depending on the field of application - including the bleaching agent component is 2 to 10 g / l, preferably 3 to 8 g / l. The application temperature can be 25 to 100 ° C, but is preferably in the range between 40 and 70 ° C.

Als Diperoxydicarbonsäuren dienten:

  • Beispiel 1) Diperoxyazelainsäure,
  • Beispiel 2) Diperoxyisophthalsäure.
The following were used as diperoxydicarboxylic acids:
  • Example 1) Diperoxyazelaic acid,
  • Example 2) Diperoxyisophthalic acid.

Die Waschversuche wurden mit Textilproben aus nicht optisch aufgehellter Baumwolle in einer Laboratoriumswaschmaschine (Launderometer) durchgeführt. Die Konzentration des vorstehend angegebenen Waschmittels betrug 3,5 g/l, die Temperatur 60 °C, die Waschdauer 30 Minuten, das Gewichtsverhältnis von Textilgut zu Waschflotte 1 : 10 und die Härte des Wassers 16 °dH. Die Persäuren (1) und (2) wurden der Waschlauge in solcher Menge zugefügt, daß die Konzentration an verfügbarem (titrierbarem) Aktivsauerstoff 120 ppm betrug. Die Mengen der eingesetzten optischen Aufheller sind der Tabelle 1 zu entnehmen.The washing tests were carried out with textile samples made from cotton which had not been optically brightened in a laboratory washing machine (launderometer). The concentration of the above-mentioned detergent was 3.5 g / l, the temperature 60 ° C, the washing time 30 minutes, the weight ratio of textile to wash liquor 1:10 and the hardness of the water 16 ° dH. The peracids (1) and (2) were added to the wash liquor in such an amount that the concentration of available (titratable) active oxygen was 120 ppm. The amounts of the optical brighteners used can be found in Table 1.

Der Weißwert der Textilproben wurde vor Beginn der Versuche und nach 10 Behandlungen photometrisch unter Verwendung von 3 Farbfiltern bestimmt und nach der bekannten von A. BERGER angegebenen Formel W = R + 3 (R - R ) errechnet, wobei Rx, Ry und Rz die mit dem Rot-, Grün-und Blaufilter gemessenen Werte angeben (vergleiche DE-OS 16 17 112). Der Weißwert vor Beginn der Versuche betrug 78,4. Die in Tabelle 1 zusammengestellten Ergebnisse (Mittelwerte aus jeweils 3 Einzelbestimmungen) zeigen, daß der erfindungsgemäß zu verwendende Aufheller in Gegenwart der Persäure die höchste Brillanz bewirkt.The white value of the textile samples was determined photometrically using 3 color filters before the start of the tests and after 10 treatments and was calculated according to the known formula W = R + 3 (R-R) given by A. BERGER, where R x , R y and R z state the values measured with the red, green and blue filters (see DE-OS 16 17 112). The white value before the start of the tests was 78.4. The results summarized in Table 1 (mean values from 3 individual determinations in each case) show that the brightener to be used according to the invention brings about the highest brilliance in the presence of the peracid.

In einer weiteren Versuchsreihe wurde die Weißgradminderung aufgehellter Textilproben bei der Behandlung mit persäurehaltigen Waschmitteln in Abwesenheit optischer Aufheller untersucht. Zu diesem Zweck wurden einige der Textilproben aus der 1. Versuchsreihe unter den gleichen Bedingungen, wie vorstehend angegeben, 3mal gewaschen, wobei lediglich der Zusatz des optischen Aufhellers unterblieb. Die in Tabelle 2 zusammengestellten Ergebnisse zeigen, daß der Weißwert der mit den Aufhellern der Formeln II bis IV aufgehellten Textilien vergleichsweise stärker abnimmt.

Figure imgb0012
Figure imgb0013
In a further series of experiments, the whiteness reduction of lightened textile samples was investigated when treated with detergents containing peracid in the absence of optical brighteners. For this purpose, some of the textile samples from the first test series were washed 3 times under the same conditions as stated above, only the addition of the optical brightener being omitted. The results summarized in Table 2 show that the white value of the textiles brightened with the brighteners of the formulas II to IV decreases comparatively more.
