- detergents and cleaning agents generally contain builders and surfactants from the group of anionic and nonionic surfactants as main components.
- Detergents may contain co-builders such as polycarboxylates, peroxy bleach, bleach activators, foam inhibitors, optical brighteners and enzymes or enzyme combinations to improve the cleaning action as further constituents.

- lipase lipase.
- cellulase is described, for example, in European patent application EP 468464 and in international patent applications WO 91/19807, WO 91/19794 or WO 90/02790.
- Graying inhibitors in the actual sense have the task of keeping the dirt detached from the fibers suspended in the liquor and preventing the dirt from settling again and thus preventing the fibers from graying, while the above-mentioned soil repellent active substances presumably function in the sense of protecting them unfold pointing fiber equipment.
- detergents which contain, as a dirt-repellent compound, a polymer of ethylene terephthalate and polyethylene oxide terephthalate, and also anionic surfactants in the form of alcohol sulfates, alcohol sulfates condensed with ethylene oxide, and mixtures thereof.
- European patent application EP 0365103 describes a surfactant composition which comprises 4 to 30% by weight of a synthetic nonionic surfactant, 25 to 80% by weight builder for this nonionic surfactant, 0.1 to 2% by weight Protease, 0 to 2 wt .-% amylase, 0.2 to 1 wt .-% cellulase, 1 to 15 wt .-% water and as a further component poly (alkylene glycol terephthalate).
- the detergents known from the prior art do not always have satisfactory dirt-repellent properties in order to prevent graying of the washed fabric as long as possible. This affects their cleaning effect.
- the object of the present invention is to provide washing and cleaning agents which have excellent cleaning action and at the same time have dirt-removing properties in order to prevent the graying of the fabrics.
- the present invention relates to a detergent and cleaning agent containing powdery surfactants, cellulase and builder, which a) contains 0.15 to 10% by weight of a dirt-repellent polymer which contains ethylene terephthalate groups of the formula
- n is an integer from 17 to 110, the molar ratio of ethylene terephthalate to polyethylene oxide terephthalate in the polymer being from about 50:50 to about 90:10, b) cellulase in an activity of 0.05 IU / g to 1.5 IU / g, and c) 1% by weight to 40% by weight of terpolymers from the monomer units of two ethylenically unsaturated carboxylic acids and / or their salts and, as a third monomer unit, vinyl alcohol and / or a vinyl alcohol derivative or a carbohydrate.
- the soil-repellent polymers according to the invention which contain groups with the formulas I and II above, are in the washing and cleaning agents according to the invention in an amount of 0.15% by weight to about 10% by weight, preferably about 0.25% by weight % to about 5% by weight, particularly preferably about 0.3% by weight to about 3% by weight.
- the molecular weight of the linking polyethylene oxide units is preferably in the range from 750 to 5000.
- the polymers can have an average molecular weight from approximately 5000 to approximately 200000. Ethylene terephthalate and polyethylene oxide terephthalate can be distributed arbitrarily in the polymer.
- Preferred polymers are those with molar ratios of ethylene terephthalate to polyethylene oxide terephthalate from about 65:35 to about 90:10, preferably from about 65:35 to about 80:20, the linking polyethylene oxide units having a molecular weight of 750-5000. preferably about 1000 to about 3000 and the polymer has a molecular weight of about 10,000 to about 50,000.
- Examples of commercially available polymers of this type are, for example, "Milease ( R ) -T" from ICI United States, Inc., Repel-0-Te ⁇ ( R ) SRP 3 from Rhönen-Poulenc and Zelcon ( R ) 8037 from DuPont.
- the dirt-repellent polymers used in agents according to the invention can be prepared by known polymerization processes, the starting materials being used in amounts such as to obtain the above-mentioned ratios of ethylene terephthalate to polyethylene oxide terephthalate.
- the processes described in US Pat. No. 3,479,212 can be used to produce suitable polymers.
- the washing and cleaning agents of the invention generally contain fine crystalline, synthetic and bound water-containing zeolite and / or alkali silicates, although agents according to the invention are not limited to these builder substances.
- the zeolite used is preferably zeolite of the A and / or P type in detergent quality. Their mixtures with zeolite NaX are also suitable, the proportion of the zeolite NaX in such mixtures normally being below 30%. They have practically no particles larger than 30 ⁇ m and preferably consist at least 80% of particles smaller than 10 ⁇ m.
- Preferred zeolites have an average particle size of less than 10 ⁇ m (measurement method: Fraunhofer diffraction; mean value of the volume distribution), preferably between 1.5 and 4.5 ⁇ m, in particular between 2.0 and 4.0 ⁇ m.
- Their calcium binding capacity which can be determined according to the information in German patent DE 24 12837, is in the range from 100 to 200 mg CaO / g.
- the content of finely divided, in particular crystalline, hydrated zeolite in the compositions is preferably 30 to 65% by weight and in particular 32 to 45% by weight, based on anhydrous active substance.
