• a typical product is Empresol N from Emsland -force GmbH, Emlichheim, Federal Republic of Germany. This is a cationic potato starch derivative with tertiary and quaternary nitrogen atoms, the cationic charge of which is evenly distributed over the entire starch chain.
• the concentration of the starch ether additive in the detergent is between 5 and 50% by weight, based on the amount of nonionic surfactants used, and the ratio of the starch ether to the plasticizing quaternary ammonium compound is between 3: 1 and 1: 3.

• Another possible quaternary ammonium compounds are the imidazoline compounds obtainable by reacting 1 mol of a Aminoalkylethylendiamins Hydroxyalkylethylendiamins or with 2 moles of a long chain, C14 -C26 fatty acid or its ester, which is then by alkylation in the quaternary imidazolinium - be converted compounds.
• Typical preferred textile plasticizers are, for example, the commercial products "Präpagen WK” and “Präpagen WKT” (Hoechst), "Adogen 442” (Ashland), which are ditallow alkyldimethylammonium salts. 1 to 10, preferably 2 to 6% by weight of these compounds are present in the detergent according to the invention.
• the alkyl polyglycol ethers of the formula I which are suitable as component a) are derived from alcohols which are prepared by reacting linear olefins with carbon monoxide and hydrogen by the known oxo process by hydroformylation and subsequent hydrogenation.
• Commercially available oxo alcohol mixtures which are suitable for the preparation of the surfactant component a) are, for example, the oxo alcohols available from Deutsche Shell Chemie Deutschen Deutschen the trade name "Dobanol", which have about 25% by weight of 2-alkyl branches .

• the textiles are not only cleaned properly, but also get a pleasant grip.
• the good foaming behavior allows the agents to be used both in the washing machine and for hand washing.
• Example 1 For comparison, an agent of the composition of Example 1 was prepared with the exception of the potato starch ether, which was replaced by the same amount of ditallow alkyl dimethyl ammonium chloride. This detergent corresponds to an agent of the prior art.
