Viscous liquid detergent or cleaning agent

Abstract

Liquid surfactant- and water-containing washing or cleaning agents which contain at least one gelling agent of the general formula (I) in which each m is independently a number in the range from 2 to 15, in particular from 2.5 to 13.5 and each n is independently a number in the range from 0 to 5, in particular from 3.5 to 4.5, and at least one salt, have a high viscosity.

Description

The present invention relates to viscous liquid detergent compositions.Detergents or cleaning agents are offered to the consumer in the form of solid or liquid products. The solid and liquid detergents or cleaning agents were originally packaged in the form of larger containers (for example boxes, bags or bottles holding up to several kilograms or litres of the agent). Recently, efforts have been made to keep the amount of washing or cleaning agents used as small as possible per washing or cleaning cycle. This leads to a concentration of their ingredients and to the substantial omission of constituents which do not contribute substantially to the washing or cleaning result, such as any fillers, or must be provided anyway by the user of the compositions, such as water. The previously customary large containers have recently become increasingly detached by significantly smaller sales units from which the quantity of the corresponding agent required for the individual washing or cleaning operation is removed, or by predosed confection forms ("unit can"). These dosage units are, for example, tablets or bags.The dosage units may be packaged in a water-insoluble film or a water-soluble film. While a water-insoluble film must be removed by the consumer before use of the metering unit, a film which dissolves upon introduction into the aqueous washing or cleaning liquor can remain on the metering unit. The latter has the advantage of facilitated metering accuracy.Therefore, in addition to tabletting pulverulent premix into tablets, the formulation of liquid or powders in water-soluble bags is of increasing importance. Corresponding products are generally distinguished from tablets by a shortened dissolution time. Short dissolution times of the dosage units in turn have an advantageous effect on the washing or cleaning result because the washing or cleaning-active effect of the dosage unit then comes to bear more quickly and can develop correspondingly longer with an equally long duration of the washing or cleaning process.Against this technical background, the present invention had the object of providing a liquid washing or cleaning agent which can optionally be made ready for single dosage and which has good dissolution properties despite high viscosity.This object is achieved by a liquid surfactant- and water-containing washing or cleaning agent comprising at least one gel former of the general formula (I) in which each m is independently a number in the range from 2 to 15, in particular from 2.5 to 13.5, and each n is independently a number in the range from 0 to 5, in particular from 3.5 to 4.5, and at least one salt.Non-integer values for m and n in the compounds of the general formula (I) occur if mixtures of alcohols of different chain length (m) are reacted with ethylene oxide and, as is customary in industry, individual compounds of different highest degree of ethoxylated content are not separated (n) before they are reacted to form the urethanes of the general formula (I). In a preferred embodiment of the invention, m in the compound of the general formula (I) is in the range from 3 to 5 and n is in the range from 3.5 to 4. Gelling agents of the general formula (I) are commercially available under the trade name Rheobyk®.The proportion of the gelling agent of the general formula (I) in the total liquid agent is preferably in the range from 0.1% by weight to 10% by weight, in particular from 0.5% by weight to 5% by weight and particularly preferably from 1 to 4% by weight.The salt in question is preferably selected from the alkali and alkaline earth halides, sulfates, acetates and mixtures thereof, in particular from sodium chloride, calcium chloride, magnesium sulfate, potassium acetate and mixtures thereof.The proportion of the salt in the total liquid agent is preferably in the range from 0.1% by weight to 10% by weight, in particular from 0.5% by weight to 6% by weight and particularly preferably from 1 to 5% by weight.The weight ratio of gelling agent of the general formula (I) to salt is preferably in the range from 1:1 to 1:10, in particular from 1:2 to 1:6.Due to the simultaneous use of the gelling agent and the salt, the liquid agents are viscous and do not lose their viscosity even after prolonged storage. Preferably, they have a viscosity of over 20 Pa·s, in particular in the range of 30 Pa·s to 200 Pa·s, measured with a shear rheometer using a plate-plate measurement system with a plate spacing of 100 μm at a shear rate of 1 s -1 and a temperature of 20° C.Particularly in the case of agents in the upper part of the viscosity range mentioned, an exact metering from a commercially available bottle can be associated with difficulties for the consumer. A further embodiment of the invention consists in a composition according to the invention portioned in a pouch of water-soluble film material sealed on all sides ready for single dosing.The liquid agent according to the invention may contain organic solvent in addition to water.

Suitable surfactants are anionic surfactants, nonionic surfactants, zwitterionic surfactants, amphoteric surfactants or cationic surfactants. It is preferred if at least one anionic surfactant and optionally additionally at least one nonionic surfactant is present.If an agent according to the invention, in particular for use in textile washing, contains anionic surfactant, it is in turn preferred that, based on the total weight of the agent, anionic surfactant is contained in a total amount of from 5% by weight to 70% by weight, more preferably 5% by weight to 60% by weight, more preferably 10% by weight to 70% by weight, in particular 10% by weight to 60% by weight, particularly preferably from 10% by weight to 40% by weight, further preferably from 25% by weight to 40% by weight.Suitable anionic surfactants of the sulfonate type are preferably C 9-13- alkylbenzenesulfonates, olefinsulfonates, i.e. mixtures of alkene- and hydroxyalkanesulfonates and disulfonates, as are obtained, for example, from C 12-18- monoolefins having a terminal or internal double bond by sulfonation with gaseous sulfur trioxide and subsequent alkaline or acidic hydrolysis of the sulfonation products.

Of interest in washing technology, preference is given to C 12- C 16- alkyl sulfates and C 12- C 15- alkyl sulfates and C 14- C 15- alkyl sulfates. Fatty alcohol ether sulfates, such as the sulfuric monoesters of straight-chain or branched C 7-21- alcohols ethoxylated with 1 to 6 mol ethylene oxide, such as 2-methyl-branched C 9-11- alcohols with an average of 3.5 mol ethylene oxide (EO) or C 12-18- fatty alcohols with 1 to 4 EO, are also suitable.Other suitable anionic surfactants are soaps.

Polyamines bearing ethylene groups as said alkylene group are also referred to as polyethyleneimine or PEI. PEI is a particularly preferred polymer according to the invention having an N atom-containing backbone. The primary amino functions in the polyamine may carry 1 or 2 polyalkoxy groups and the secondary amino functions 1 polyalkoxy group, wherein not every amino function needs to be alkoxy group substituted.
