Description

'Liquid detergent verfärbunqsinhibierendes

The present invention relates to a liquid verfärbungsinhibierendes detergent containing water-insoluble builders, which do not settle even after prolonged storage.

have liquid detergent over powder-form detergents a Rei¬ he of handling advantages, which are becoming increasingly liquid detergent lately of interest. As long as such detergents contain only lösli¬ che ingredients, preparing the formulation and preparation generally no difficulties. Now, however, a phosphate substitute has been found with the water-insoluble zeolite A, whose incorporation ii preparing liquid detergent because of its tendency to sedimentation difficulties. There has therefore been no lack of attempts, with a significant content of zeolite len sedimentation-stable liquid detergent herzustel¬. Examples of patent applications that deal blems with the solution of this Pro¬, for example, the German patent applications DE-A-36 05 978, DE-A-36 25 189, Canadian Patent CA-B-1, 202.857, European patent applications EP-A-75 976, EP-A-142 185, EP-A-301 882 and the earlier, non-prepublished deut¬ specific patent application P 39 29 591. disadvantages of Wasch¬ described therein are slow, for example, their tendency to gel on dilution with water, or the content of a wash ineffective in itself Antigelier eans or inadequate sedimentation stability or insufficient voltage Scho¬ white or light colored textiles against discoloration in the joint washing colored textiles.

The object of the present invention is to provide an aqueous, liquid, detergent verfärbungsinhibierendes containing Zeo¬ lith A, which tends not even upon prolonged storage time to sediment, but it satisfies the performance requirements of modern liquid detergent.

The present invention is therefore a liquid verfär¬ bungsinhibierendes detergent containing zeolite A, nichtioni¬ rule surfactants and water, which is characterized in that it contains verfär¬ bungsinhibierende polymers is largely or completely free of electrolytes, nonionic and optionally anionic surfactants in a weight ratio of 1: 0 to 1: 1, wherein the concentration of Zeo¬ lith a and the type and concentration of the surfactants are selected so that the detergent has a yield strength of at least 6 Pa and lamellar Flüs¬ sigkristalle contains.

Electrolytes this invention will be understood in the context of especially soluble ^ builder salts, such as alkaline phosphates, sulfates, sulfonates -Sul-, silicates, carbonates or borates. Electrolytes are allowed to be present höch¬ least about 5 wt .-% in the inventive detergent.

The detergent according to the invention contain as discoloration-polymers polymer constituents based on N-vinylpyrrolidone and / or N-vinylimidazole and / or N-vinyloxazolidone. It can be used both homopolymers and copolymers of said compounds. The Polymerbe¬ constituents based on N-vinylpyrrolidone having a molecular weight in the range of about 10 000 to about 1 000 000. Particularly suitable homopolymers have a molecular weight of about 15 000 to about 700 000. In copolymers which are suitable for the inventive detergents , the proportion of N-vinyl pyrrolidone is at least about 50% of the copolymer. Suitable comonomer mers are for example vinyl acetate, acrylonitrile and maleic anhydride. The preferred molecular weight of suitable copolymers is in the range of about 20 000 to about 200 000. detergent containing poly-N-Vi nylimidazol are preferred.

is important for the sedimentation stability of the detergent according to the invention that they have a yield strength of at least 6 Pa. a yield stress of the detergent from 6 to 40 Pa is preferred, preferably from 8 to 25 Pa and especially from 8 to 15 Pa. Detergent having a flow point 2 in the areas mentioned above are stable to sedimentation, if one so selects the A-zeolite content and the content of nonionic surfactants and the nature of the nonionic surfactant used in that the erfindungsge¬ MAESSEN detergents contain lamellar liquid crystals. The content of lith Zeo¬ A is approximately within a range of 10 to 35 wt .-% einzu¬ provide, with a range of about 15 to about 30 wt .-% is preferred.

Essential to the formation of lamellar liquid crystalline phases are the type and amount of surfactant used in the liquid detergent. The Aus¬ education or the existence of lamellar liquid-crystalline phases can most easily find in a polarizing microscope with heating stage. Between crossed polarizers to show the different phases Doppel¬ calculation, leading to cloudy with sen for lamellar liquid crystalline Pha¬ characteristic textures while isotropic phases such. E £. Solutions, however appear black.

In the inventive washing contained wt .-% πichtio- African surfactant 10 to about 30 microns. Suitable nonionic surfactants are beispiels¬ as adducts of 3 to 5 mol ethylene oxide with fatty alcohols having 12 to 16 carbon atoms. This is, for example, lauryl alcohol, are attached to the 4 moles of ethylene oxide. But also mixtures of nonionic Ten¬ side, corresponding to this definition are suitable. One example is a 4: 1 mixture of a Ci2 / Ci4-fatty alcohol with 3 moles of ethylene oxide and of a Ci2 / Ci6 fatty alcohol with 5 moles of ethylene oxide.

Anionic surfactants which are suitable for the inventive detergents, surfactants from the class of sulfonates and sulfates. Surfactants of the sulfonate type are preferably Cg to Ci3-Alkylbenzolsulfona- te, in particular Ci2 alkyl benzene sulfonate and sulfonates based on oleochemicals such as the esters of sulfofatty acids (ester sulfonates), for example. B. α- acids the sulfonated Methylester of hydrogenated coconut, palm kernel or tallow fatty. Suitable surfactants of the sulfate type, the sulfuric säuremonoester of primary alcohols of natural and synthetic origin, for example, jump, ie of fatty alcohols such. As coconut fatty alcohol, tallow fatty alcohol, oleyl alcohol, lauryl, myristyl, palmityl or stearyl alcohol or lkoholen the CIQ ~ b '* s C20-0 χoa and those of secondary alcohols of this chain length V, said Schwefelsäuremonoester of primary alcohols on oleochemical the base Schwefelsäuremonoester the ethoxylated with 1 to 6 moles of ethylene oxide, alcohols, such as linear C1 are also preferred -. to CI8 fatty alcohols or 2-methyl-branched Cg to Cn alcohols containing on average 3.5 moles of ethylene oxide are suitable Furthermore. are sulfated fatty acid onoglyceride. The sulfates and sulfonates can be present individually or in admixture.

Suitable anionic surfactants are soaps, preferably saturated fatty acid soaps, such as the alkali metal or alkanolamine salts of lauric acid, myristic acid, palmitic acid and stearic acid useful. are suitable in particular from natural fatty acids, for. Example from coconut, palm kernel or tallow soap mixtures derived. Also suitable are such Sei¬ fen, of which 50 to 100 wt .-% of saturated C12 to Cig-Fettsäureseifef. and are composed of from 0 to 50 wt .-% of oleic acid soap.
