Description

Enzvmkombinationshaltioe liquid washing and cleaning agents

The invention relates to liquid detergents and cleaning agents which contain protease, amylase and cellulase and water-soluble and optionally water-insoluble builders and a nonionic surfactant component which consists essentially of alkyl or alkenyl glycoside.

The use of enzymes or enzyme combinations to improve the cleaning action of detergents and cleaning agents is generally known in the field of detergents and cleaning agents. The most commonly used enzymes include protease, amylase, cellulase and lipase. These enzymes can each have different properties from one another and can come from different sources.

The prior art also describes enzyme combinations which are intended to improve the cleaning action of the detergents and cleaning agents in the case of a wide variety of enzymatically degradable soils.

European patent application EP 0365103 discloses a detergent which contains an organic, nonionic surfactant and builder for this surfactant and an enzyme combination consisting of protease, amylase and cellulase.

European patent application EP 0425214 describes an enzyme-containing washing and cleaning agent which contains anionic and / or nonionic surfactants, preferably a builder and an enzyme combination of three enzymes, namely protease, amylase and either lipase or cellulase.

From the international patent application WO 92/19708 a liquid detergent is known which, in addition to anionic and nonionic surfactants, contains an enzyme combination of protease and a second enzyme such as cellulase, which is stabilized with the aid of an aromatic borate ester.

International patent application WO 93/11215 discloses a liquid detergent containing anionic or nonionic surfactant, citric acid or contains a water-soluble salt thereof, propanediol and boric acid, protease and cellulose as active components. The enzyme combination is stabilized by propanediol and boric acid in such a way that these two components are mixed with the other constituents before the citric acid or its salt is added. It is also disclosed that ethoxylated surfactants avoid the denaturation of cellulase.

Surfactants based on glucose and other sugars, the alkyl glycosides with long-chain alkyl groups, are non-ionic surfactants. Detergents which contain alkyl glycosides in combination with at least one conventional anionic surfactant are described in European patent application EP 070074. Detergents which contain alkyl glycosides and anionic surfactants are also known from European patent application EP 092877. Furthermore, liquid detergents are known from European patent application EP 105556, which contain alkyl glycosides, certain other nonionic surfactants and anionic surfactants. From international patent application WO 86/2943, alkyl glycoside-containing liquid detergents are known which additionally contain conventional anionic surfactants.

The above-mentioned enzyme-containing detergents and cleaning agents all have the disadvantage that the enzymes contained therein have only a limited stability and the washing properties deteriorate significantly after short storage times. This also applies to agents to which enzyme stabilizers have been added.

The object of the present invention is to provide a washing and cleaning agent which ensures sufficient stability of the enzymes contained and has improved washing activity.

The invention relates to a detergent and cleaning agent containing surfactant, protease, amylase, cellulase and builder, which contains a nonionic surfactant component which comprises at least 50% by weight, in particular at least 80% by weight a glycoside of the formula (I)

^ OGn (I) in which R ^{1 is} an alkyl or alkenyl radical having 8 to 22 carbon atoms, G is a glycose unit and n is a number from 1 to 10.

Surprisingly, it was found that the agent according to the invention, compared to the prior art, has similar and sometimes even better washing properties at lower doses and that the enzymes contained also have good activity even after prolonged storage.

The glycosides suitable for incorporation into the surfactant mixtures according to the invention are compounds of the general formula I in which R * is an alkyl or alkenyl radical having 8 to 22 carbon atoms, G is a glycose unit and n is a number between 1 and 10. Such compounds and their preparation are described, for example, in European patent applications EP 092355, EP 301 298, EP 357969 and EP 362671 or US Pat. No. 3547828. The glycoside component ((G) _n in formula I) is an oligomer or polymer from naturally occurring aldose or ketose monomers, in particular glucose, mannose, fructose, galactose, talose, gulose, altrose, or alelose , Idose, ribose, arabinose, xylose and lyxose. The oligomers consisting of such glycosidically linked monomers are characterized not only by the type of sugar they contain, but also by their number, the so-called degree of oligomerization. The degree of oligo erization (n in formula I) generally assumes fractional numerical values as the quantity to be determined analytically; it is between 1 and 10, for the glycosides preferably used below 1.5, in particular between 1.2 and 1.4. The preferred monomer building block is glucose because of its good availability.

The alkyl or alkenyl moiety (R ¹ in formula I) of the glycosides contained in the agents according to the invention preferably also originates from easily accessible derivatives of renewable raw materials, in particular from fatty alcohols, although also their branched chain isomers, in particular so-called oxo alcohols. can be used to produce usable glycosides. Accordingly, the primary alcohols with linear octyl, decyl, dodecyl, tetradecyl, hexadecyl or octadecyl radicals and mixtures thereof are particularly suitable. Particularly preferred alkyl glycosides contain a coconut fatty alkyl rest, ie mixtures with essentially Rl = dodecyl and Rl = tetradecyl. Due to the production process, the glycosides can contain small amounts, for example 1 to 2%, of unreacted free fatty alcohol, which does not have a disadvantageous effect on the properties of the products produced therewith, but is even advantageous in the case of liquid products. Fatty alcohols can also be used as additional skin-protecting components in shampoos, hand-washing pastes, etc.

The proportion of further nonionic surfactant present in addition to the glycoside is up to 50% by weight, preferably at most 25% by weight, in particular 0.5% by weight to 20% by weight, based on the total nonionic surfactant component. The further nonionic surfactants that come into question include the alkoxylates, in particular the ethoxylates and / or propoxylates of saturated or mono- to polyunsaturated linear or branched-chain alcohols having 10 to 22 carbon atoms, preferably 12 to 18 carbon atoms. The degree of alkoxylation of the alcohols is generally between 1 and 20, preferably between 3 and 10. They can be prepared in a known manner by reacting the corresponding alcohols with the corresponding alkylene oxides. The derivatives of fatty alcohols are particularly suitable, although their branched chain isomers, in particular so-called oxo alcohols, can also be used to prepare usable alkoxylates. Accordingly, the alkoxylates, in particular the ethoxylates, of primary alcohols with linear, in particular dodecyl, tetradecyl, hexadecyl or octadecyl radicals and mixtures thereof, can be used. Corresponding alkoxylation products of alkylamines, vicinal diols and carboxamides which correspond to the alcohols mentioned with regard to the alkyl part can also be used. In addition, there are the ethylene oxide and / or propylene oxide insertion products of fatty acid alkyl esters, as can be prepared in accordance with the process specified in international patent application WO 90/13533, and fatty acid polyhydroxyamides, as in accordance with the processes in the US patents US 1 985424, US 2016962 and US 2703798 and the international patent application WO 92/06984 can be considered.

Such a nonionic surfactant system, consisting of glycoside of the formula (I) and optionally further nonionic surfactant, is preferably used in the agents according to the invention in amounts of 1% by weight to 50% by weight, in particular contain from 1 wt .-% to 40 wt .-%. If the agent according to the invention is a cleaning agent, for example a manual or machine dishwashing agent or a cleaning agent for hard surfaces, the nonionic surfactant content can also be lower and is then preferably 0.5% by weight. up to 20% by weight, in particular 0.9% by weight to 10% by weight.

In addition, the agents according to the invention can contain further surfactants, preferably synthetic anionic surfactants of the sulfate or sulfonate type, in amounts of preferably not more than 20% by weight, in particular from 0.1% by weight to 18% by weight based on total mean. Synthetic anionic surfactants which are particularly suitable for use in the agents according to the invention are the alkyl and / or alkenyl sulfates with 8 to 22 carbon atoms which carry an alkali metal, ammonium or alkyl or hydroxyalkyl substituted ammonium ion as countercation. The derivatives of fatty alcohols with in particular 12 to 18 carbon atoms and their branched-chain analogs, the so-called oxo alcohols, are preferred. The alkyl and alkenyl sulfates may be prepared be¬ by reacting the corresponding alcohol component with a Usually, for chen sulfating agent, ^{'particularly} sulfur trioxide or chlorosulfonic acid, and subsequent neutralization with alkali metal, ammonium or alkyl relationship as hydroxyalkyl-substituted ammonium bases in bekann¬ ter manner .

In particular, those soap mixtures are preferred which are composed of 50% by weight to 100% by weight of saturated C 1 -C 6 fatty acid soaps and up to 50% by weight of oleic acid soap. Soap is preferably contained in amounts of 0.1% by weight to 5% by weight. In particular, however, higher amounts of soap of up to 20% by weight can also be contained in liquid agents.
