Description

The present invention relates to a liquid detergent composition, in particular a concentrated liquid detergent composition, comprising at least one fatty alcohol ether sulfate, at least one betaine and ethanol, wherein the concentrated composition has a salt concentration of about 0.2 to about 10 wt.%, and wherein the concentrated composition can be diluted with water to a ready-to-use liquid detergent composition. The detergent composition is preferably used for manual dishwashing. The present invention further relates to the use of such a detergent composition for cleaning hard surfaces, in particular dishes, and to a method for producing a detergent composition, which method comprises diluting the concentrated liquid detergent composition with water.In order to minimize packaging, storage and transport costs, many products in the homecare sector have meanwhile been offered as concentrates which contain a higher proportion of washing- and cleaning-active ingredients than conventional products. The concentrates are either used by the consumer directly for washing or cleaning, in which case a smaller amount corresponding to the concentration is required, or they are first diluted with a certain amount of water and only then applied as a conventional product. In a number of countries, in particular in countries in which the majority of people have a low incidence, concentrates are offered which, after dilution with water, are used by the consumer like conventional hand dishwashing detergents. Detergents and cleaners, which are available in the form of concentrates, thus provide an excellent solution to low-revenue consumers who seek financial relief because the preparation, packaging, transportation and storage of concentrates is less costly as compared to conventional product forms. For these reasons, concentrates are also of interest for sustainability-oriented consumers who regard the reduction of emissions as at least one of their priorities during their purchase decisions.In addition to the above-mentioned advantages, which can be associated with concentrates, a corresponding product must meet a complex requirement profile in order to be accepted by the consumer. Thus, in addition to the primary washing and cleaning action and the transport and storage stability, consumers expect not only an attractive appearance, a pleasant fragrance and good skin compatibility, but also, in particular, simple handling and metering. For this reason, in a number of applications, for example manual dishwashing or the cleaning of other hard surfaces, consumers prefer products with increased viscosity, in particular after dilution with water, which can be metered more precisely and run more slowly on oblique and in particular vertical surfaces, i.e. act on the surface to be cleaned longer. Moreover, it is generally desirable that the final product form rapidly, easily and without much effort (i.e., slightly to moderately shaking the aqueous mixture for only a few seconds without the need for repeated shaking) and that the final product exhibit favorable flow characteristics and excessive bubbling and / or foaming after dilution of the concentrate with water. Furthermore, the diluted detergent composition should also be stable on storage.However, if the diluted concentrate is to have a sufficiently increased viscosity, this generally means that the viscosity of the undiluted concentrate is still much higher and accordingly the handling properties and the solubility of the concentrate are hardly acceptable or no longer acceptable.Although a bulk of liquid detergent compositions in the form of concentrates are known in the art and widely marketed, there remains a need for improved compositions which are easily flowable, on the one hand, in concentrated form and, on the other hand, self-thicken upon dilution with water to an extent which is perceived by the consumer as functional and easy to handle.Surprisingly, it has been found that a certain salt concentration in the concentrated liquid detergent composition results in the desired properties with respect to the viscosity of the water diluted detergent composition. A salt concentration in the detergent concentrate of about 0.2 to about 10 wt. %, preferably about 1 to about 7.5 wt. %, more preferably about 1.5 to about 6 wt. %, particularly preferably about 2 to about 4 wt. %, has proven particularly advantageous here, based on active substance and total weight of the detergent concentrate.

Preference is given to using alkyl glycosides having an average degree of oligomerization b of from 1.1 to 3.0. From the point of view of application, preference is given to alkyl glycosides whose degree of oligomerization is less than 1.7 and in particular between 1.2 and 1.6. As glycosidic sugar, preferably xylose, but in particular glucose, is used. The alkyl or alkenyl radical R 26 can be derived from primary alcohols having 8 to 18, preferably 8 to 14, carbon atoms. Typical examples are caproic alcohol, caprylic alcohol, capric alcohol and undecyl alcohol and technical mixtures thereof, as are obtained, for example, in the course of the hydrogenation of technical fatty acid methyl esters or in the course of the hydrogenation of aldehydes from RoELEN oxo synthesis. Preferably, the alkyl or alkenyl radical R' is derived, however, from lauryl alcohol, myristyl alcohol, cetyl alcohol, palmoleyl alcohol, stearyl alcohol, isostearyl alcohol or oleyl alcohol. Mention may also be made of elaidyl alcohol, petrolatumyl alcohol, arachidyl alcohol, gadoleyl alcohol, behenyl alcohol, erucyl alcohol and technical mixtures thereof.Particularly preferred APGs are non-alkoxylated (a=0) and satisfy formula (XII) R 27 O[G] c( XII) in which R 27 as before, is a linear or branched, saturated or unsaturated alkyl radical having 4 to 22 carbon atoms, [G] is a glycosidically linked sugar radical, preferably glucose radical, and c is a number from 1 to 10, preferably 1.1 to 3, in particular 1.2 to 1.6. Accordingly preferred alkyl polyglycosides are, for example, C 8-10- and a C 12-14- alkyl polyglucoside having a DP degree of 1.4 or 1.5, in particular C 8-10- alkyl 1,5-glucoside and C 12-14- alkyl 1,4-glucoside.Suitable anionic surfactants are, for example, fatty alcohol sulfates, fatty alcohol ether sulfates, dialkyl ether sulfates, monoglyceride sulfates, alkylbenzenesulfonates, olefinsulfonates, alkanesulfonates, ethersulfonates, n-alkyl ethersulfonates, estersulfonates and ligninsulfonates. Also usable are fatty acid cyanamides, sulfosuccinates (sulfosuccinic acid esters), in particular sulfosuccinic acid mono- and di-C 8-18- alkyl esters, sulfosuccinamates, sulfosuccinamides, fatty acid isethionates, acylaminoalkanesulfonates (fatty acid taurides), fatty acid sarcosinates, ether carboxylic acids and alkyl (ether) phosphates, and α-sulfo fatty acid salts, acyl glutamates, monoglyceride disulfates and alkyl ethers of glycerol disulfate. Linear alkylbenzenesulfonates, fatty alcohol sulfates and / or fatty alcohol ether sulfates, especially the fatty alcohol sulfates, are preferred. Fatty alcohol sulfates are products of sulfating reactions on corresponding alcohols, while fatty alcohol ether sulfates are products of sulfating reactions on alkoxylated alcohols. Alkoxylated alcohols are understood to mean the reaction products of alkylene oxide, preferably ethylene oxide, with alcohols, preferably with longer-chain alcohols. As a rule, n moles of ethylene oxide and one mole of alcohol form a complex mixture of addition products of different degrees of ethoxylation, depending on the reaction conditions. A further embodiment of the alkoxylation consists in the use of mixtures of the alkylene oxides, preferably of the mixture of ethylene oxide and propylene oxide. Preferred fatty alcohol ether sulfates are the sulfates of lower ethoxylated fatty alcohols having 1 to 4 ethylene oxide units (EO), in particular 1 to 2 EO, for example 1.3 EO. In the alkyl benzene sulphonates, those having about 12 C atoms in the alkyl part are particularly preferred, for example linear sodium C 10-18- alkyl benzene sulphonate. Preferred olefin sulfonates have a carbon chain length of 14 to 16. The anionic surfactants are preferably used as sodium salts, but can also be present as other alkali metal or alkaline earth metal salts, for example magnesium salts, and in the form of ammonium or mono-, di-, tri- or tetraalkylammonium salts, and in the case of the sulfonates can also be present in the form of their corresponding acid, for example dodecylbenzenesulfonic acid.Suitable amphoteric surfactants are, for example, betaines of the formula (VII) (R 18)( R 19)( R 20) N + CH 2 COO -( VII) in which R 18 denotes an alkyl radical having 8 to 25, preferably 10 to 21, carbon atoms and R 19 and R 20 denote identical or different alkyl radicals having 1 to 3 carbon atoms, optionally interrupted by heteroatoms or heteroatom groups, in particular C 10-18- alkyldimethylcarboxymethylbetaine and C_NER285-alkylamidopropyldimethylcarboxymethylbetaine.Suitable cationic surfactants are, inter alia, the quaternary ammonium compounds of the formula (XIII) (R 28)( R 29)( R 30)( R 31) N + X -( XIII) in which R 28 to R 31 are four identical or different, in particular two long- and two short-chain, alkyl radicals and X - is an anion, in particular a halide ion, for example didecyldimethylammonium chloride, alkylbenzyldidecylammonium chloride and mixtures thereof. Further suitable cationic surfactants are the quaternary surface-active compounds, in particular having a sulfonium, phosphonium, iodonium or arsonium group, which are also known as antimicrobial active ingredients. By using quaternary surface-active compounds with antimicrobial action, the agent can be configured with an antimicrobial action or its antimicrobial action, which may already be present due to other ingredients, can be improved.In preferred embodiments, no builder substances are present in compositions according to the invention.In preferred embodiments, water-soluble builder substances may be present in compositions according to the invention.

In the context of the invention, both a detergent concentrate or the diluted detergent composition and the cleaning liquor formed by these compositions have a respective cleaning performance. The cleaning performance can be determined by methods known to those skilled in the art.The term "cleaning liquor" is understood to mean the use solution containing the cleaning agent, which acts on the surfaces to be cleaned, in particular dishes, and thus comes into contact with the stains present on the surfaces. The cleaning liquor usually arises when the cleaning process begins and the agent is diluted with water, for example in a suitable container, preferably in a wash basin for manual dishwashing.Preferred embodiments of uses and compositions according to the invention achieve such advantageous cleaning performance even at low temperatures, in particular in a temperature range of about 10° C. to about 30° C., preferably about 15° C. to about 30° C., preferably about 18° C. to about 25° C., particularly preferably about 25° C., very particularly preferably about 20° C.Preferred embodiments comprise all liquid, gel or paste-like dosage forms of agents according to the invention, which may optionally also consist of a plurality of phases and may be present in compressed or non-compressed form, e.g. in the form of a non-aqueous cleaning agent or a non-aqueous paste or in the form of an aqueous cleaning agent or a water-containing paste. Liquid agents are generally preferred. Furthermore, the agent can be present as a one-component system. Such agents consist of one phase. Alternatively, a means can also consist of a plurality of phases. Such a means is accordingly divided into several components.In preferred embodiments, concentrated agents according to the invention may be present in pre-portioned form (e.g. pouch, pouch).In preferred embodiments, the concentrated agent according to the invention is enveloped in a pre-portioned form by a water-soluble coating. The water-soluble wrapper is preferably formed from a water-soluble sheet material selected from the group consisting of polymers or polymer blends. The wrapper may be formed from one or two or more layers of the water soluble sheet material. The water-soluble film material of the first layer and the further layers, if present, may be the same or different. It is preferred that the water-soluble coating contains polyvinyl alcohol or a polyvinyl alcohol copolymer. Water-soluble coatings containing polyvinyl alcohol or a polyvinyl alcohol copolymer have good stability with a sufficiently high water solubility, in particular cold water solubility.

The production of polyvinyl alcohol is usually carried out by hydrolysis of polyvinyl acetate, since the direct synthetic route is not possible. The same applies to polyvinyl alcohol copolymers which are correspondingly produced from polyvinyl acetate copolymers. It is preferred if at least one layer of the water-soluble coating comprises a polyvinyl alcohol whose degree of hydrolysis constitutes 70 to 100 mol %, preferably 80 to 90 mol %, particularly preferably 81 to 89 mol % and in particular 82 to 88 mol %. In a preferred embodiment, the water-soluble packaging consists to an extent of at least 20% by weight, particularly preferably to an extent of at least 40% by weight, very particularly preferably to an extent of at least 60% by weight and in particular to an extent of at least 80% by weight, of a polyvinyl alcohol whose degree of hydrolysis is 70 to 100 mol %, preferably 80 to 90 mol %, particularly preferably 81 to 89 mol % and in particular 82 to 88 mol %. A polymer selected from the group comprising (meth)acrylic acid-containing (co)polymers, polyacrylamides, oxazoline polymers, polystyrenesulfonates, polyurethanes, polyesters, polyethers, polylactic acid or mixtures of the above polymers can additionally be added to a polyvinyl alcohol-containing film material suitable for producing the water-soluble covering. A preferred additional polymer is polylactic acids. Preferred polyvinyl alcohol copolymers comprise, in addition to vinyl alcohol, dicarboxylic acids as further monomers. Suitable dicarboxylic acids are itaconic acid, malonic acid, succinic acid and mixtures thereof, with itaconic acid being preferred. Likewise preferred polyvinyl alcohol copolymers comprise, in addition to vinyl alcohol, an ethylenically unsaturated carboxylic acid, its salt or its ester. Particularly preferably, such polyvinyl alcohol copolymers contain, in addition to vinyl alcohol, acrylic acid, methacrylic acid, acrylic acid esters, methacrylic acid esters or mixtures thereof. It may be preferred for the film material to contain further additives. The film material may contain, for example, plasticizers such as dipropylene glycol, ethylene glycol, diethylene glycol, propylene glycol, glycerol, sorbitol, mannitol or mixtures thereof. Further additives include, for example, release aids, fillers, crosslinking agents, surfactants, antioxidants, UV absorbers, antiblocking agents, antiadhesive agents or mixtures thereof. Suitable water-soluble films for use in the water-soluble envelopes of the water-soluble packages according to the invention are films which are sold by the company MonoSol LLC, for example under the name M8720, M8630, M8312, M8440, M7062, C8400 or M8900. Also suitable are films which are sold under the name SH2601, SH2504, SH2707 or SH2701 by Nippon Gohsei. Other suitable films include Solublon® PT, Solublon® GA, Solublon® KC, or Solublon® KL films from Aicello Chemical Europe GmbH, or VF-HP films from Kuraray. The water-soluble coating preferably has at least partially a bitter substance having a bitter value between 1,000 and 200,000, in particular those selected from quinine sulfate (bitter value=10,000), naringine (bitter value=10,000), sucrose octaacetate (bitter value=100,000), quinine hydrochloride and mixtures thereof. In particular, the outer surface of the water-soluble envelope is at least partially coated with a bitter substance having a bitter value of between 1,000 and 200,000. In this context, it is particularly preferable for the water-soluble coating to be coated to an extent of at least 50%, preferably at least 75% and very particularly preferably at least 90%, with the bitter substance having a bitter value of between 1,000 and 200,000. The bitter substance having a bitter value of between 1,000 and 200,000 can be applied, for example, by means of printing, spraying or painting. According to the invention, the water-soluble envelope has at least one continuously encircling sealing seam which lies substantially in one plane. This is favorable from the process standpoint, since for a circumferential sealing seam which lies substantially in one plane, only a single sealing step is necessary, optionally using only a single sealing tool. The continuously encircling sealing seam leads to a better closure compared to such coverings having a plurality of sealing seams and an excellent tightness of the sealing seam and thus of the covering itself. Leakage of product from the wrapper, e.g., onto the surface of the portion, would be disadvantageous because the consumer would then contact the product. However, this is to be avoided as much as possible in the case of a washing or cleaning agent portion with a water-soluble casing. The water-soluble wrapper can preferably be made from at least 2 packaging parts. It is not necessary here for the at least two packaging parts to be different. They can preferably be made of the same material and in the same way.
