Abstract

Liquid detergents which contain as essential components a diarylpyrazoline brightener and a non-ionic and a cationic surfactant produce in a one-stage treatment bath excellent brightening effects and a pleasant handle of the fabric. They are far superior in this respect to conventional detergents based on anionic brighteners and surfactants.

Description

Gegenstand der vorliegenden Erfindung sind Flüssigwasch­mittel mit hervorragenden weichmachenden und aufhellenden Effekt, die - im Gegensatz zu den meisten handelsüblichen Waschmitteln - praktisch frei von anoinischen Tensiden und anionischen Weißtönern sind.The present invention relates to liquid detergents with an excellent softening and lightening effect which, in contrast to most commercial detergents, are practically free of anoinic surfactants and anionic whiteners.

Wegen des steigenden Anteils an Synthesefasern im Wasch­gut besteht ein wachsendes Interesse, flüssige Waschmittel herzustellen, die größere Mengen von nichtionischen Ten­siden enthalten und denen kationische Weichmacher beige­geben sind, um neben dem Wascheffekt einen Avivageeffekt zu erzielen, der der gewaschenen Wäsche einen weichen Griff und Antistatik verleiht. Diese Formulierungen bieten damit einen Vorteil gegenüber dem üblichen zweistufigen Verfahren, bei dem nach dem Waschgang kationische Weich­macher im Spülbad angewendet werden.Because of the increasing proportion of synthetic fibers in the laundry, there is a growing interest in the production of liquid detergents which contain large amounts of nonionic surfactants and to which cationic plasticizers have been added in order to achieve a softening effect in addition to the washing effect, which gives the washed laundry a soft feel and antistatic properties . These formulations thus offer an advantage over the conventional two-stage process in which cationic plasticizers are used in the rinsing bath after the wash cycle.

Es ist jedoch bekannt, daß rein nichtionische Formu­lierungen auf die im Handel befindlichen anionischen Weißtöner einen retardierenden Effekt ausüben, so daß nicht die gleichen Weißeffekte erhalten werden wie in anionisch formulierten Waschmitteln.However, it is known that purely nonionic formulations have a retarding effect on the commercially available anionic white toners, so that the same white effects are not obtained as in anionically formulated detergents.

Durch die Mitverwendung von kationischen Substanzen, bei­spielsweise quaternären Ammoniumsalzen langkettiger Fett­amine oder Amid-Amine, wird dieses Problem noch verstärkt, da die anionischen Weißtöner durch Salzbildung mit dem quartärnären Ammoniumsalzen inaktiviert werden und teil­weise unlösliche Niederschläge bilden.This problem is exacerbated by the use of cationic substances, for example quaternary ammonium salts of long-chain fatty amines or amide amines, since the anionic whiteners are inactivated by salt formation with the quaternary ammonium salts and in some cases form insoluble precipitates.

Es ist deshalb bereits vorgeschlagen worden (vgl. US-A 4 233 167), anstelle der üblichen nur 2 Sulfogruppen enthaltenden Stilben-Weißtöner solche aufhellenden Verbindungen in die Waschmittel einzuarbeiten, die 3 bis 5 Sulfogruppen im Wirkstoffmolekül aufweisen, da sich wegen der höheren Löslichkeit dieser Verbindungen die Bildung von Niederschlägen vermeiden läßt. Es ist jedoch bekannt, daß höher sulfonierte Typen eine geringere Substantivität besitzen und somit die erzielbaren Weißeffekte geringer sind als mit Weißtönern mit zwei Sulfogruppen.It has therefore already been proposed (cf. US Pat. No. 4,233,167), instead of the usual stilbene whitener containing only 2 sulfo groups, to incorporate into the detergents those brightening compounds which have 3 to 5 sulfo groups in the active substance molecule because of the higher solubility these compounds prevent the formation of precipitation. However, it is known that higher sulfonated types have a lower substantivity and thus the white effects which can be achieved are less than with whiteners with two sulfo groups.

Eine andere Lösung des Problems besteht gemäß EP-A 19 702 in der Verwendung neuartiger, kationischer, auf Baumwolle substantiver Weißtöner, die naturgemäß keine negative Wechselwirkung mit kationischen Weichmachern haben können. Unbefriedigend an diesem Systemen ist jedoch die Tatsache, daß das Waschgut aus anderen Quellen bereits die üblicher­ weise verwendeten anionischen Weißtönern mitbringt, die dann eine gegenseitige Inaktivierung mit den erfindungs­gemäßen kationischen Weißtönern bewirken.Another solution to the problem, according to EP-A 19 702, is the use of novel, cationic, white toners substantive on cotton, which naturally cannot have a negative interaction with cationic plasticizers. What is unsatisfactory with this system, however, is the fact that the laundry from other sources is already the more common brings along used anionic whiteners, which then cause mutual inactivation with the cationic whiteners according to the invention.

Es wurde nun überraschenderweise gefunden, daß man diese Mängel bzw. Nachteile vermieden werden können, wenn man Waschmittel verwendet, die im wesentlichen frei von den obengenannten anionischen Weißtönern und Hilfsmitteln sind, und neben anderen üblichen Zusatzstoffen als charakteristische Bestandteile

  • a) einem Weißtöner auf Basis von 1,3-Diarylpyrazolinen
  • b) ein nichtionisches Tensid und
  • c) ein kationisches Tensid als Weichmacher
enthalten.It has now surprisingly been found that these shortcomings or disadvantages can be avoided by using detergents which are essentially free from the above-mentioned anionic whiteners and auxiliaries, and in addition to other customary additives as characteristic constituents
  • a) a white toner based on 1,3-diarylpyrazolines
  • b) a nonionic surfactant and
  • c) a cationic surfactant as a plasticizer
contain.

Der Begriff "Waschmittel" ist im Rahmen dieser Erfindung im weitesten Sinne zu verstehen. Er umfaßt sowohl Reini­gungsmittel verschiedenster Art als auch Gewebe und Haus­haltswaschmittel sowie Wäschenachbehandlungsmittel. Bevor­zugt ist die Verwendung als "einstufiges" Haushaltswasch- und spülmittel.The term “detergent” is to be understood in the broadest sense within the scope of this invention. It includes a wide range of cleaning agents as well as fabrics and household detergents as well as laundry aftertreatment agents. Use as a "one-step" household detergent and dishwashing detergent is preferred.

Als nicht-ionische Tenside kommen handelsübliche Produkte in Betracht, z.B. die Additionsprodukte von Ethylenoxid mit höheren aliphatischen Alkoholen mit 6 bis 50 und C-Atomen, Polyoxyalkylenester organischer Säuren wie höherer Fettsäuren, Harzsäuren, Tallölsäuren und Säuren der Oxydationsprodukte des Erdöls, sowie Alkylenoxid­addukte höherer Fettsäureamide, wobei der Fettsäureteil in der Regel 8 bis 22 C-Atome aufweist und mit 10 bis 50 Mol Ethylenoxid kondensiert ist.Commercially available products are suitable as nonionic surfactants, for example the addition products of ethylene oxide with higher aliphatic alcohols with 6 to 50 and C atoms, polyoxyalkylene esters of organic acids such as higher fatty acids, resin acids, tall oil acids and acids of the oxidation products of petroleum, and alkylene oxide adducts of higher fatty acid amides, the fatty acid part generally having 8 to 22 carbon atoms and being condensed with 10 to 50 mol of ethylene oxide.

These are of course chosen so that they are compatible with the main components of the detergent.

Die nicht-ionogenen Tenside werden in Mengen von 5 bis 80 Gew.-%, vorzugsweise 20-60 Gew.-% eingesetzt. Die Konzen­tration des Textilweichmachers beträgt 1 bis 30 Gew.-%, vorzugsweise 5-20 Gew.-%.
