Abstract

Compositions comprising at least one aminoalkylsiloxane and at least one higher alkyl-modified amido aminosiloxane modified by a compound having at least two hydroxyl groups selected from the group consisting of hydroxycarboxylic acids, monosaccharides, disaccharides and mixtures thereof are described along with fabric treatment agents containing such compositions, the use of such compositions and agents for treating fabrics, and containers with such compositions and/or agents.

Description

The present invention relates to a composition for reducing crease formation on textiles, which comprises a mixture of at least one aminoalkylsiloxane and at least one higher alkyl-modified amido aminosiloxane modified by hydroxycarboxylic acids and/or mono- and/or disaccharides having in each case at least two hydroxyl groups, and to the use of this composition for the treatment of textiles.
Greases and wrinkles in textiles are caused by folding and creasing the textiles as a result of the action of external forces, especially by wearing and by washing the textiles, wherein the outward facing part of the textile is strained and simultaneously the inward facing part of the textile is exposed to a pressure. At the molecular level this can especially lead to the formation of hydrogen bonds that following a decrease in the action of the force can at least partially stop the state of deformation. This problem arises principally with cotton and the hydrogen bonds that are present here between cellulose molecules.
In the prior art it has already been described that crease formation in textiles can be reduced by using polysiloxanes.
Thus, in U.S. Pat. No. 4,923,623, compositions are described for reducing crease formation in textiles, which involve a starch-containing liquid and comprise aminosilicones.
The applications WO 96/15309 and WO 96/15310 describe a composition for reducing the crease formation in textiles, which comprises effective amounts of a silicone and a film forming polymer as well as a liquid carrier, the composition being essentially free of starch and modified starch.
EP 0 058 493 describes compositions for treating textiles, based on combinations of specific polyorganosiloxanes, wherein inter alia the reduction of crease formation is also cited.
Moreover, silicone polymer-containing fiber treatment agents are described in the applications WO 02/088456, US 2002/0120057, EP 1 033 434 and EP 1 081 272.
Surprisingly, it has now been found that a composition comprising at least one aminoalkylsiloxane and at least one higher alkyl-modified amido aminosiloxane modified by hydroxycarboxylic acids and/or mono- and/or disaccharides having in each case at least two hydroxyl groups, possesses particularly advantageous properties in regard to anti-wrinkle behavior.

A further subject of the present invention is a container that comprises an inventive composition or an inventive textile treatment agent. In a preferred embodiment, this container concerns a spray. Therefore, in a preferred embodiment, the container includes a spray dispenser, and the cleaning agent is preferably applied from the container by the use of this spray dispenser.
The preferred spray dispenser is a manually operated spray dispenser, selected in particular from the group including aerosol spray dispensers pressurized gas containers; also known inter alia as spray cans), self generated pressure spray dispensers, pump spray dispensers and trigger spray dispensers, particularly pump spray dispensers and trigger spray dispensers with a container made of transparent polyethylene or polyethylene terephthalate. Spray dispensers are extensively described in WO 96/04940 (Proctor & Gamble) and in the US patents cited therein concerning spray dispensers, all of which are referred to in this respect and their content is hereby incorporated in this application. Trigger spray dispensers and pump spray dispensers are advantageous in comparison with pressurized gas containers as no propellant need be employed.
Consequently, particularly when pressurized gas containers are used, the inventive composition can also comprise one or a plurality of propellants. They are usually comprised in an amount of 1 to 80 wt. %, preferably 1.5 to 30 wt. %, particularly 2 to 10 wt. %, particularly preferably 2.5 to 8 wt. %, above all 3 to 6 wt. %.
Propellants, according to the invention, are usually propellant gases, particularly liquefied or compressed gases. The choice depends on the product to be sprayed and the field of application. When using compressed gases such as nitrogen, carbon dioxide or nitrous oxide, which are generally insoluble in the liquid cleaning agent, the operating pressure is reduced with each actuation of the valve. Liquefied gases that are soluble in, or that themselves act as solvents for the cleaning agent, offer the advantage as propellants of a constant operating pressure and uniform distribution, because the propellant evaporates in air and then expands several hundred times in volume.
Accordingly, the following are suitable propellants (names according to INCI): butane, carbon dioxide, dimethyl carbonate, dimethyl ether, ethane, hydrochlorofluorocarbon 22, hydrochlorofluorocarbon 142b, hydrofluorocarbon 152a, hydrofluorocarbon 134a, hydrofluorocarbon 227ea, isobutane, isopentane, nitrogen, nitrous oxide, pentane, propane. However, the use of chlorofluorocarbons (CFC) as propellants is preferably widely avoided and especially totally avoided due to their harmful effect on the ozone layer of the atmosphere that protects against harmful UV radiation.
Preferred propellants are liquid gases. Liquid gases are gases that can be transformed from the gaseous into the liquid state at mostly already low pressures and 20° C. However liquid gases are particularly understood to be the hydrocarbons propane, propene, butane, butene, isobutane (2-methylpropane), isobutene (2-methylpropene, isobutylene) and their mixtures, which occur as by products from distilling and cracking oil in oil refineries as well as in natural gas processing in gasoline separation. The inventive composition particularly preferably comprises one or a plurality of propellants selected from propane, butane and/or isobutene, especially propane and butane, above all a mixture of propane, butane and isobutene.
In a further inventively preferred embodiment, the inventive composition concerns a fabric softener. It is usually introduced into the rinse cycle of an automatic washing machine.
In addition to the components cited above, the inventive composition, particularly as a fabric softener, can comprise one or a plurality of the components listed below.

Fatty acids—singly or in mixtures—used for manufacturing fatty alcohols are fatty acids such as caproic acid, caprylic acid, capric acid, 2-ethylhexanoic acid, lauric acid, myristic acid, palmitic acid, palmitoleic acid, isostearic acid, stearic acid, hydroxystearic acid (ricinoleic acid), dihydroxystearic acid, oleic acid, linoleic acid, petroselic acid, elaidic acid, arachic acid, behenic acid and erucic acid as well as their industrial mixtures, as for example occur from the pressure cracking of natural fats and oils such as oleic acid, linoleic acid, linolenic acid, and especially rape seed oil fatty acid, soya oil fatty acid, sunflower oil fatty acid, tallow fatty acid. In principle, all fatty acids with similar chain distributions are suitable.
The content of unsaturated fractions of these fatty acids or fatty acid esters—when required—is adjusted by means of the known catalytic hydrogenation process to a desired iodine number or by mixing fully hydrogenated fatty components with non-hydrogenated fatty components.
The iodine number, as a quantitative measure for the average degree of saturation of a fatty acid, is the quantity of iodine that is taken up by 100 g of the compound whose double bonds are to be saturated.
Partially hydrogenated C_8/18coco or palm fatty acids, rape seed oil fatty acids, sunflower oil fatty acids, soya oil fatty acids and tallow oil fatty acids, with iodine numbers in the range ca. 80 to 150 and especially industrial C_8/18coco fatty acids are used, wherein optionally, a choice of cis/trans isomers such as elaidic acid-rich C_16/18fatty acid fractions can be advantageous. They are commercial products and are offered by various companies under their respective trade names.
The addition of pH adjustors can be considered for bringing the pH of the inventive composition into the desired range. Any known acid or alkali can be added, in so far as their addition is not forbidden on technological or ecological grounds or grounds of protection of the consumer. The amount of these adjustors does not normally exceed 10 wt. % of the total formulation.
Exemplary suitable pH adjustors are inorganic acids, such as hydrochloric acid, phosphoric acid, HBr and sulfuric acid as well as organic acids, such as formic acid, acetic acid, propionic acid, butyric acid, valeric acid, caproic acid, caprylic acid, 2-ethylhexanoic acid, capric acid, lauric acid, isotridecanoic acid, myristic acid, palmitic acid, palmitoleic acid, stearic acid, isostearic acid, oleic acid, elaidic acid, petroselic acid, linoleic acid, linolenic acid, elaeostearic acid, arachidonic acid, gadoleic acid, behenic acid and erucic acid as well as their technical mixtures. Suitable C₂-C₁₂dicarboxylic acids can also be employed, such as succinic acid, maleic acid, fumaric acid, glutaric acid, adipic acid and dodecane dioic acid. Hydroxy-functionalized polyvalent carboxylic acids, such as e.g. malic acid, tartaric acid and especially citric acid, are particularly suitable.
The inventive compositions are preferably aqueous and in a preferred embodiment, especially as rinse softeners, have a pH below 9, particularly preferably below 7.5, especially below 6, most preferably below 5, specifically from 2 to 4.5.
In a preferred embodiment, the preferably liquid compositions additionally comprise electrolytes for stabilization purposes, preferably alkali metal and/or alkaline earth metal salts, particularly preferably alkali metal and/or alkaline earth metal halides, especially the alkaline earth metal halides of magnesium and calcium, specifically magnesium and/or calcium chloride.
In a preferred embodiment, the inventive compositions additionally comprise odor absorbers. In the context of the invention, odor absorbers are one or a plurality of metal salts of a linear or branched, saturated or unsaturated, mono or polyhydroxylated fatty acids containing at least 16 carbon atoms and/or of a resin acid with the exception of the alkali metal salts, as well as any mixtures thereof.
A particularly preferred linear or branched, saturated or unsaturated, mono or polyhydroxylated fatty acid containing at least 16 carbon atoms is ricinoleic acid. A particularly preferred resin acid is abietic acid.
Preferred metals are the transition metals and the lanthanoids, especially the transition metals of groups VIIIa, Ib and IIb of the periodic system as well as lanthanum, cerium and neodymium, particularly preferably cobalt, nickel, copper and zinc, most preferably zinc. Although the cobalt, nickel and copper salts and the zinc salts are similarly effective, the zinc salts are preferred, however, on toxicological grounds.
One or a plurality of metal salts of ricinoleic acid and/or of abietic acid, preferably zinc ricinoleate and/or zinc abietate, especially zinc abietate are advantageously and therefore particularly preferably employed as the deodorizing substances.
In the context of the invention, cyclodextrins as well as any mixtures of the abovementioned metal salts with cyclodextrins have likewise proven to be further suitable deodorizing substances, preferably in a weight ratio of 1:10 to 10:1, particularly preferably 1:5 to 5:1 and especially 1:3 to 3:1. The term “cyclodextrin” here includes all known cyclodextrins, i.e. both unsubstituted cyclodextrins containing 6 to 12 glucose units, especially alpha, beta and gamma cyclodextrins and their mixtures and/or their derivatives and/or their mixtures.
For better dispersion, suspension or emulsification of the advantageously employable fabric softeners, the composition advantageously further comprises surfactants. The surfactants are selected from the group of the anionic, non-ionic, cationic, zwitterionic and amphoteric surfactants.
In a preferred embodiment, the inventive compositions can further comprise surfactants. The additional use of surfactants enhances the conditioning characteristics and contributes to an improved storage stability and dispersibility or emulsifiability of the individual conditioning agent components.
The added non-ionic surfactants are preferably alkoxylated, advantageously ethoxylated and/or propoxylated, particularly primary alcohols having preferably 8 to 18 carbon atoms and an average of 1 to 12 mol ethylene oxide (EO) and/or 1 to 10 mol propylene oxide (PO) per mol alcohol. C₈-C₁₆Alcohol alkoxylates, advantageously ethoxylated and/or propoxylated C₁₀-C₁₅alcohol alkoxylates, particularly C₁₂-C₁₄alcohol alkoxylates, with an ethoxylation degree between 2 and 10, preferably between 3 and 8, and/or a propoxylation degree between 1 and 6, preferably between 1.5 and 5, are particularly preferred. The alcohol group can preferably be linear or particularly preferably be methyl branched in the 2-position or comprise a mixture of linear and methyl-branched groups, as is typically present in oxo-alcohol groups. Particularly preferred are, however, alcohol ethoxylates with linear groups from alcohols of natural origin with 12 to 18 carbon atoms, e.g. from coco-, palm-, tallow- or oleyl alcohol, and an average of 2 to 8 EO per mol alcohol. Exemplary preferred ethoxylated alcohols include C_12-14alcohols with 3 EO or 4 EO, C_9-11alcohols with 7 EO, C_13-15alcohols with 3 EO, 5 EO, 7 EO or 8 EO, C_12-18alcohols with 3 EO, 5 EO or 7 EO and mixtures thereof, as well as mixtures of C_12-14alcohol with 3 EO and C_12-18alcohol with 5 EO. The cited degrees of ethoxylation and propoxylation constitute statistical average values that can be a whole or a fractional number for a specific product. Preferred alcohol ethoxylates and propoxylates have a narrowed homolog distribution (narrow range ethoxylates/propoxylates, NRE/NRP). In addition to these non-ionic surfactants, fatty alcohols with more than 12 EO can also be used. Examples of these are tallow fatty alcohol with 14 EO, 25 EO, 30 EO or 40 EO.
Alkoxylated amines, advantageously ethoxylated and/or propoxylated, particularly primary and secondary amines having preferably 1 to 18 carbon atoms per alkyl chain and an average of 1 to 12 mol ethylene oxide (EO) and/or 1 to 10 mol propylene oxide (PO) per mol amine, are also suitable.
Furthermore, as additional non-ionic surfactants, alkyl glycosides that satisfy the general Formula RO(G)_x, can be added e.g. as compounds, particularly with anionic surfactants, where R means a primary linear or methyl-branched, particularly 2-methyl-branched, aliphatic group containing 8 to 22, preferably 12 to 18 carbon atoms and G stands for a glycose unit containing 5 or 6 carbon atoms, preferably for glucose. The degree of oligomerization x, which defines the distribution of monoglycosides and oligoglycosides, is any number between 1.0 and 10, preferably between 1.2 and 1.4.
Another class of preferred non-ionic surfactants which are used either as the sole non-ionic surfactant or in combination with other non-ionic surfactants, are alkoxylated, preferably ethoxylated or ethoxylated and propoxylated fatty acid alkyl esters preferably containing 1 to 4 carbon atoms in the alkyl chain, more particularly the fatty acid methyl esters which are described, for example, in Japanese patent application JP 58/217598 or which are preferably produced by the process described in International Patent application WO-A-90/13533.
Non-ionic surfactants of the amine oxide type, for example N-cocoalkyl-N,N-dimethylamine oxide and N-tallow alkyl-N,N-dihydroxyethylamine oxide, and the fatty acid alkanolamides may also be suitable.
The so-called gemini surfactants can be considered as further surfactants. Generally speaking, such compounds are understood to mean compounds that have two hydrophilic groups and two hydrophobic groups per molecule. As a rule, these groups are separated from one another by a “spacer”. The spacer is usually a hydrocarbon chain that is intended to be long enough such that the hydrophilic groups are a sufficient distance apart to be able to act independently of one another. These types of surfactants are generally characterized by an unusually low critical micelle concentration and the ability to strongly reduce the surface tension of water. In exceptional cases, however, not only dimeric but also trimeric surfactants are meant by the term gemini surfactants.
Suitable gemini surfactants are, for example, sulfated hydroxy mixed ethers according to the German Patent application DE-A-43 21 022 or dimer alcohol bis- and trimer alcohol tris sulfates and ether sulfates according to the international patent application WO-A-96/23768. Blocked end group dimeric and trimeric mixed ethers according to the German Patent application DE-A-195 13 391 are especially characterized by their bifunctionality and multifunctionality. Thus, the cited blocked end group surfactants possess good wetting properties and are therefore poor foamers, such that they are particularly suited for use in automatic washing or cleaning processes.
However, gemini polyhydroxyfatty acid amides or poly-polyhydroxyfatty acid amides, such as those described in the international Patent applications WO-A-WO-A-95/19953, WO-A-95/19954 and WO-A-95/19955 can also be used.
Other suitable surfactants are polyhydroxyfatty acid amides corresponding to the Formula
in which RCO stands for an aliphatic acyl group with 6 to 22 carbon atoms, R⁵for hydrogen, an alkyl or hydroxyalkyl group with 1 to 4 carbon atoms and [Z] for a linear or branched polyhydroxyalkyl group with 3 to 10 carbon atoms and 3 to 10 hydroxyl groups. The polyhydroxyfatty acid amides are known substances, which may normally be obtained by reductive amination of a reducing sugar with ammonia, an alkylamine or an alkanolamine and subsequent acylation with a fatty acid, a fatty acid alkyl ester or a fatty acid chloride.
The group of polyhydroxyfatty acid amides also includes compounds corresponding to the following Formula,
in which R is a linear or branched alkyl or alkenyl group containing 7 to 12 carbon atoms, R⁶is a linear, branched or cyclic alkyl group or an aryl group containing 2 to 8 carbon atoms and R⁷is a linear, branched or cyclic alkyl group or an aryl group or an oxyalkyl group containing 1 to 8 carbon atoms, C_1-4alkyl or phenyl groups being preferred, and [Z] is a linear polyhydroxyalkyl group, of which the alkyl chain is substituted by at least two hydroxyl groups, or alkoxylated, preferably ethoxylated or propoxylated derivatives of that group.
[Z] is preferably obtained by reductive amination of a reducing sugar, for example glucose, fructose, maltose, lactose, galactose, mannose or xylose. The N-alkoxy- or N-aryloxy-substituted compounds may then be converted, for example according to the teaching of the international application WO-A-95/07331, into the required polyhydroxyfatty acid amides by reaction with fatty acid methyl esters in the presence of an alkoxide as catalyst
Preferred non-ionic surfactants are one or a plurality of linear or branched, saturated or unsaturated C_10-22alcohols that are alkoxylated with ethylene oxide (EO) and/or propylene oxide (PO) with an alkoxylation degree of up to 30, preferably ethoxylated C_10-18fatty alcohols with an ethoxylation degree of less than 30, preferably 1 to 20, particularly 1 to 12, particularly preferably 1 to 8, most preferably 2 to 5, for example C_12-14fatty alcohol ethoxylates with 2, 3 or 4 EO or a mixture of the C_12-14fatty alcohol ethoxylates with 3 and 4 EO in the weight ratio of 1 to 1 or isotridecyl alcohol ethoxylates with 5, 8 or 12 EO, such as for example described in DE 40 14 055 C2 (Grillo-Werke), to which reference is made and the contents of which are incorporated into this application.
The non-ionic surfactants can normally be present in quantities of up to 50 wt. %, preferably from 0.1 to 40 wt. %, particularly preferably from 0.5 to 30 wt. %, especially from 2 to 25 wt. %, each based on the total agent.
The inventive compositions can optionally further comprise amphoteric surfactants. Besides numerous mono to trialkylated amine oxides, the betaines illustrate an important class.
Betaines illustrate known surfactants that are principally manufactured by carboxyalkylation, preferably carboxymethylation of amino compounds. The starting materials are preferably condensed with carboxylic acid halides or their salts, especially with sodium chloroacetate, one mole salt being formed per mole betaine. Furthermore, the addition of unsaturated carboxylic acids, such as for example acrylic acid, is also possible. Concerning the nomenclature and in particular the distinction between betaines and “true” amphoteric surfactants, reference is made to the paper of U. Ploog in Seifen-Öle-Fette-Wachse, 108, 373 (1982). Additional reviews of this topic can be found, for example, by A. O'Lennick et al. in HAPPI, Nov. 70 (1986), S. Holzman et al. in Tens. Surf. Det. 23, 309 (1986), R. Bibo et al. in Soap Cosm. Chem. Spec, Apr. 46 (1990) and P. Ellis et al. in Euro Cosm. 1, 14 (1994). Examples of suitable betaines are illustrated by the carboxyalkylation products of secondary and especially tertiary amines, which have the formula (XVIII)
in which R¹stands for alkyl and/or alkenyl groups with 6 to 22 carbon atoms, R²for hydrogen or alkyl groups with 1 to 4 carbon atoms, R³for alkyl groups with 1 to 4 carbon atoms, n for numbers from 1 to 6 and X¹for an alkali metal and/or alkaline earth metal or ammonium. Typical examples are the carboxymethylation products of hexylmethylamine, hexyldimethylamine, octyldimethylamine, decyidimethylamine, dodecylmethylamine, dodecyidimethylamine, dodecylethylmethylamine, C_12/14cocoalkyldimethylamine, myristyidimethylamine, cetyidimethylamine, stearyldimethylamine, stearylethylmethylamine, oleyldimethylamine, C_16/18tallowalkyldimethylamine as well as their industrial mixtures.
In addition, carboxyalkylation products of amido amines which have the formula (XIX) come into consideration,
in which R⁴CO stands for an aliphatic group with 6 to 22 carbon atoms and 0 or 1 to 3 double bonds, m for numbers from 1 to 3 and R², R³, n and X²have the above meanings. Typical examples are the reaction products of fatty acids containing 6 to 22 carbon atoms, namely caproic acid, caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid, palmitoleic acid, stearic acid, isostearic acid, oleic acid, elaidic acid, petroselic acid, linoleic acid, linolenic acid, elaeostearic acid, arachidonic acid, gadoleic acid, behenic acid and erucic acid as well as their technical mixtures, with N,N-dimethylaminoethylamine, N,N-dimethylaminopropylamine, N,N-diethylaminoethylamine and N,N-diethylaminopropylamine, which are condensed with sodium chloroacetate. A condensation product of C_8/18cocofatty acid-N,N-dimethylaminopropylamide with sodium chloroacetate is preferably employed.
In addition, suitable starting materials for the betaines that can be employed in the context of the invention are imidazolines of formula (XX),
in which R⁵stands for an alkyl group with 5 to 21 carbon atoms, R⁶for a hydroxyl group, a OCOR⁵— or NHCOR⁵group and m stands for 2 or 3. These substances are also known materials, which, for example, can be obtained by condensation/cyclization of 1 or 2 moles fatty acid with polyamines, such as, for example aminoethylethanolamine (AEEA) or diethylenetriamine. Mixtures of different open chain betaines illustrate the corresponding carboxyalkylation products. Typical examples are condensation products of the abovementioned fatty acids with AEEA, preferably imidazolines based on lauric acid or in turn C_12/14coco fatty acid, which are subsequently betainized with sodium chloroacetate.
In a preferred embodiment, the inventive compositions exist in liquid form. In order to obtain a liquid consistence, it may be advisable to add both a liquid organic solvent as well as water. Thus, the inventive laundry conditioning agents optionally comprise solvents.
Solvents that can be especially added to rinse softeners originate, for example, from the group of mono- or polyhydric alcohols, alkanolamines or glycol ethers, in so far that they are miscible with water in the defined concentration range. Preferably, the solvents are selected from ethanol, n- or i-propanol, butanols, glycol, propane diol or butane diol, glycerine, diglycol, propyl diglycol or butyl diglycol, hexylene glycol, ethylene glycol methyl ether, ethylene glycol ethyl ether, ethylene glycol propyl ether, ethylene glycol mono-n-butyl ether, diethylene glycol methyl ether, diethylene glycol ethyl ether, propylene glycol methyl-, -ethyl- or -propyl ether, butoxy propoxy propanol (BPP), dipropylene glycol methyl-, or -ethyl ether, diisopropylene glycol monomethyl, or -ethyl ether, methoxy-, ethoxy- or butoxy triglycol, 1-butoxyethoxy-2-propanol, 3-methyl-3-methoxybutanol, propylene glycol t-butyl ether as well as mixtures of these solvents.
Some glycol ethers are available under the trade names Arcosolv® (Arco Chemical Co.) or Cellosolve®, Carbitol® or Propasol® (Union Carbide Corp.); ButylCarbitol®, HexylCarbitol®, MethylCarbitol®, and Carbitol® itself, (2-(2-ethoxy)ethoxy)ethanol also belong to this group, for example. The choice of the glycol ether can be easily made by the expert on the basis of volatility, water-solubility, content by percentage weight of the total dispersion and suchlike. Pyrrolidone solvents, such as N-alkyl pyrrolidones, for example N-methyl-2-pyrrolidone or N—C₈-C₁₂alkyl pyrrolidone or 2-pyrrolidone can also be added. Further preferred as sole solvents or as a component of a mixture of solvents are glycerine derivatives, particularly glycerine carbonate.
Alcohols that can be added in the present invention as cosolvents include liquid polyethylene glycols with a low molecular weight, for example polyethylene glycols with a molecular weight of 200, 300, 400 or 600. Additional suitable cosolvents are other alcohols, for example (a) lower alcohols, such as ethanol, propanol, isopropanol and n-butanol, (b) ketones, such as acetone and methyl ethyl ketone, (c) C₂-C₄polyols, such as a diol or a triol, for example ethylene glycol, propylene glycol, glycerine or mixtures thereof. From the class of diols, 1,2-octane diol is particularly preferred.
In a preferred embodiment, the inventive composition comprises one or a plurality of solvents from the group that includes C₁-C₄monoalcohols, C₂-C₆glycols, C₃-C₁₂glycol ethers and glycerine, particularly ethanol. The inventive C₃-C₁₂glycol ethers comprise alkyl or alkenyl groups with less than 10 carbon atoms, preferably up to 8, particularly up to 6, particularly preferably 1 to 4 and most preferably 2 to 3 carbon atoms.
Preferred C₁-C₄monoalcohols are ethanol, n-propanol, iso-propanol and tert.-butanol. Preferred C₂-C₆glycols are ethylene glycol, 1,2-propylene glycol, 1,3-propylene glycol, 1,5-pentane diol, neopentyl glycol and 1,6-hexane diol, particularly ethylene glycol and 1,2-propylene glycol.

The inventive composition, especially as a rinse softener, can comprise one or a plurality of solvents in a quantity of usually up to 40 wt. %, advantageously 0.1 to 30 wt. %, particularly 2 to 20 wt. %, particularly preferably 3 to 15 wt. %, most preferably 5 to 12 wt. %, for example 5.3 or 10.6 wt. %, each based on the total agent.
In a preferred embodiment, the inventive composition optionally comprises water in an amount of more than 50 wt. %, particularly 60 to 95 wt. %, particularly 70 to 93 wt. % and most preferably 80 to 90 wt. %.
In addition, the inventive composition can comprise one or more typical auxiliaries and additives, particularly selected from the group of the builders, enzymes, bleaching agents, bleach activators, electrolytes, pH adjustors, complexing agents, fragrances, perfume carriers, fluorescence agents, colorants, foam inhibitors, anti-graying inhibitors, anti-creasing agents, antimicrobials, germicides, fungicides, antioxidants, antistatics, ironing auxiliaries, UV-absorbers, optical brighteners, antiredeposition agents, viscosity regulators, pearlizers, color-transfer inhibitors, anti-shrinkage agents, corrosion inhibitors, preservatives, water-proofing and impregnation agents, hydrotropes, silicone oils as well as swelling and non-slip agents.
In a preferred embodiment, the inventive composition optionally comprises, in addition, one or a plurality of chelating agents.
The INCI term “chelating agents” are also known as sequestrants and are ingredients that are capable of complexing and inactivating metal ions so as to prevent their detrimental action on stability or on the appearance of the agent, e.g. turbidity. It is important to complex the calcium and magnesium ions in hard water, as they are incompatible with numerous ingredients. Complexing heavy metal ions like iron or copper slows down the oxidative decomposition of the finished agent.
Further suitable chelating agents as named in INCI are for example the following that are described in more detail in the International Cosmetic Ingredient Dictionary and Handbook: aminotrimethylene phosphonic acid, beta-alanine diacetic acid, calcium disodium EDTA, citric acid, cyclodextrin, cyclohexanediamine tetraacetic acid, diammonium citrate, diammonium EDTA, diethylenetriamine pentamethylene phosphonic acid, dipotassium EDTA, disodium azacycloheptane diphosphonate, disodium EDTA, disodium pyrophosphate, EDTA, etidronic acid, galactaric acid, gluconic acid, glucuronic acid, HEDTA, hydroxypropyl cyclodextrin, methyl cyclodextrin, pentapotassium triphosphate, pentasodium aminotrimethylene phosphonate, pentasodium ethylenediamine tetramethylene phosphonate, pentasodium pentetate, pentasodium triphosphate, pentetic acid, phytic acid, potassium citrate, potassium EDTMP, potassium gluconate, potassium polyphosphate, potassium trisphosphonomethylamine oxide, ribonic acid, sodium chitosan methylene phosphonate, sodium citrate, sodium diethylenetriamine pentamethylene phosphonate, sodium dihydroxyethylglycinate, sodium EDTMP, sodium gluceptate, sodium gluconate, sodium glycereth-1 polyphosphate, sodium hexametaphosphate, sodium metaphosphate, sodium metasilicate, sodium phytate, sodium polydimethylglycinophenolsulfonate, sodium trimetaphosphate, TEA-EDTA, TEA-polyphosphate, tetrahydroxyethyl ethylenediamine, tetrahydroxypropyl ethylenediamine, tetrapotassium etidronate, tetrapotassium pyrophosphate, tetrasodium EDTA, tetrasodium etidronate, tetrasodium pyrophosphate, tripotassium EDTA, trisodium dicarboxymethyl alaninate, trisodium EDTA, trisodium HEDTA, trisodium NTA and trisodium phosphate.
Preferred chelating agents are tertiary amines, particularly tertiary alkanolamines (amino alcohols). The alkanolamines possess both amino and hydroxyl and/or ether groups as functional groups. Particularly preferred tertiary alkanolamines are triethanolamine and tetra-2-hydroxypropylethylenediamine (N,N,N′,N′-tetrakis-(2-hydroxypropyl)ethylenediamine). Particularly preferred combinations of tertiary amines with zinc ricinoleate and one or a plurality of ethoxylated fatty alcohols as the non-ionic solubilizer as well as optional solvents are described in DE 40 14 055 C2 (Grillo-Werke) to which reference is made in this context and the contents of which are hereby incorporated into this application.
A particularly preferred chelating agent is the etidronic acid (1-hydroxyethylidene-1,1-diphosphonic acid, 1-hydroxyethane-1,1-diphosphonic acid, HEDP, acetophosphonic acid, INCI Etidronic Acid) including its salts. In a preferred embodiment, the inventive agent accordingly comprises etidronic acid and/or one or more of its salts as the chelating agent.
In a preferred embodiment, the inventive composition comprises a combination of chelating agents from one or a plurality of tertiary amines and one or a plurality of additional chelating agents, preferably one or a plurality of chelating acids or their salts, particularly from triethanolamine and/or tetra-2-hydroxypropylethylenediamine and etidronic acid and/or one or a plurality of its salts.
The inventive composition comprises chelating agents in quantities of typically 0 to 20 wt. %, advantageously 0.1 to 15 wt. %, particularly 0.5 to 10 wt. %, particularly preferably 1 to 8 wt. %, most preferably 1.5 to 6 wt. %, for example 1.5, 2.1, 3 or 4.2 wt. %.
In a further embodiment, the inventive composition optionally comprises one or a plurality of viscosity regulators that preferably function as thickeners. The viscosity of the agent can be measured using standard methods (for example using a Brookfield-Viscosimeter RVD-VII at 20 rpm and 20° C., spindle 3) and lies preferably in the range from 10 to 5000 mPas. Preferred agents in liquid to gel form have viscosities from 20 to 4000 mPas, particularly preferably from 40 to 2000 mPas.
Suitable thickeners are inorganic or polymeric organic compounds. Mixtures of a plurality of thickeners can also be used.
The inorganic thickeners include, for example, polysilicic acids, mineral clays like montmorillonite, zeolites, silicic acids, aluminum silicates, layered silicates and bentonites.
The organic thickeners come from the groups of the natural polymers, derivatives of natural polymers and the synthetic polymers.
Exemplary, naturally occurring polymers that can be used as thickeners are xanthane, agar agar, carrageen, tragacanth, gum Arabic, alginates, pectins, polyoses, guar meal, galan gum, locust tree bean flour, starches, dextrins, gelatines and casein.
Modified natural products occur mainly from the group of modified starches and celluloses, examples being carboxymethyl cellulose and other cellulose ethers, hydroxyethyl and hydroxypropyl cellulose, highly etherified methyl hydroxyethyl cellulose as well as bean flour ether.
A major group of thickeners that are widely used in the most varied applications are the synthetic polymers such as polyacrylic and polymethacrylic compounds that can be crosslinked or non-crosslinked and optionally cationically modified, vinyl polymers, polycarboxylic acids, polyethers, activated polyamide derivatives, castor oil derivatives, polyimines, polyamides and polyurethanes. Exemplary polymers are acrylic resins, ethyl acrylate acrylamide copolymers, acrylate ester methacrylate ester copolymers, ethyl acrylate acrylic acid methacrylic acid copolymers, N-methylol methacrylamide, maleic anhydride methyl vinyl ether copolymers, polyether polyol copolymers as well as butadiene styrene copolymers.
Additional suitable thickeners are derivatives of organic acids as well as their alkoxide adducts, for example aryl polyglycol ethers, carboxylated nonylphenol ethoxylate derivatives, sodium alginate, diglycerine monoisostearate, non-ionic ethylene oxide adducts, coco fatty acid diethanolamide, isododecenyl succinic anhydride as well as galactomannan.
Thickeners from the cited classes of substances are commercially available and are offered, for example, under the trade names Acusol®-820 (methacrylic acid (stearylalkohol-20-EO)ester-acrylic acid copolymer, 30% in water, Rohm & Haas), Dapral®-GT-282-S (alkylpolyglycol ether, Akzo), Deuterol®-Polymer-11 (dicarboxylic acid copolymer, Schöner GmbH), Deuteron®-XG (anionic heteropolysaccharide based on β-D-glucose, D-mannose, D-glucuronic acid, Schöner GmbH), Deuteron®-XN (non-iogenic polysaccharide, Schöner GmbH), Dicrylan®-Verdicker-O (ethylene oxide adduct, 50% in water/isopropanol, Pfersse Chemie), 50% and EMA®-81 (ethylene-maleic anhydride copolymer, Monsanto), EMA®-91 (polyurethane emulsion, 19-21% in water/diglycol ether, Rohm & Haas), Mirox®-AM (anionic acrylic acid acrylate copolymer dispersion, 25% in water, Stockhausen), SER-AD-FX-1100 (hydrophobic urethane polymer, Servo Delden), Shellflo®-S (high molecular weight polysaccharide, stabilized with formaldehyde, Shell), Shellflo®-XA (Xanthane biopolymer, stabilized with formaldehyde, Shell), Keizan, Keltrol T (Kelco).
In a further preferred embodiment, the inventive composition optionally comprises one or a plurality of enzymes, especially cellulases.
In addition, the composition can optionally comprise UV absorbers, which absorb onto the treated textiles and improve the light stability of the fibers and/or the light stability of the various ingredients of the formulation. UV-absorbers are understood to mean organic compounds (light-protective filters) that are able to absorb ultra violet radiation and emit the absorbed energy in the form of longer wavelength radiation, for example as heat. Compounds, which possess these desired properties, are for example, the efficient radiationless deactivating compounds and derivatives of benzophenone having substituents in position(s) 2-and/or 4. Also suitable are substituted benzotriazoles, such as for example the water-soluble sodium salt of 3-(2H-benzotriazole-2-yl)-4-hydroxy-5-(methylpropyl)benzenesulfonic acid (Cibafast® H), acrylates, which are phenyl-substituted in position 3 (cinnamic acid derivatives) optionally with cyano groups in position 2, salicylates, organic Ni complexes, as well as natural products such as umbelliferone and the endogenous urocanic acid. The biphenyl and above all the stilbene derivatives such as for example those described in EP 0 728 749 A, and commercially available as Tinosorb® FD or Tinosorb® FR from Ciba, are of particular importance. As UV-B absorbers can be cited: 3-benzylidenecamphor or 3-benzylidenenorcamphor and its derivatives, for example 3-(4-methylbenzylidene)camphor, as described in EP 0 693 471 B1; 4-aminobenzoic acid derivatives, preferably the 2-ethylhexyl ester of 4-(dimethylamino)benzoic acid, the 2-octyl ester of 4-(dimethylamino)benzoic acid, and the amyl ester of 4-(dimethylamino)benzoic acid; esters of cinnamic acid, preferably the 2-ethylhexyl ester of 4-methoxycinnamic acid, the propyl ester of 4-methoxycinnamic acid, the isoamyl ester of 4-methoxycinnamic acid, the 2-ethylhexyl ester of 2-cyano-3,3-phenylcinnamic acid, (Octocrylene); esters of salicylic acid, preferably the 2-ethylhexyl ester of salicylic acid, the 4-isopropylbenzyl ester of salicylic acid, the homomenthyl ester of salicylic acid; derivatives of benzophenone, preferably 2-hydroxy-4-methoxybenzophenone, 2-hydroxy-4-methoxy-4′-methylbenzophenone, 2,2′-dihydroxy-4-methoxybenzophenone; esters of benzalmalonic acid, preferably the di-2-ethylhexylester of 4-methoxybenzmalonic acid; triazine derivatives, such as, for example 2,4,6-trianilino-(p-carbo-2′-ethyl-1′-hexyloxy)-1,3,5-triazine and octyl triazone, as described in EP 0 818 450 A1 or dioctyl butamidotriazone (Uvasorb® HEB); propane-1,3-diones, such as for example 1-(4-tert.-butylphenyl)-3-(4′-methoxyphenyl)propane-1,3-dione; ketotricyclo(5.2.1.0)decane derivatives, such as described in EP 0 694 521 B1. Further suitable are 2-phenylbenzimidazole-5-sulfonic acid and its alkali metal-, alkaline earth metal-, ammonium-, alkylammonium-, alkanolammonium- and glucammonium salts; sulfonic acid derivatives of benzophenones, preferably 2-hydroxy-4-methoxybenzophenone-5-sulfonic acid and its salts; sulfonic acid derivatives of 3-benzylidenecamphor, such as for example 4-(2-oxo-3-bornylidenemethyl)benzene sulfonic acid and 2-methyl-5-(2-oxo-3-bornylidene)sulfonic acid and their salts.

Naturally, the UV-A and UV-B filters can also be added as mixtures. Beside the cited soluble materials, insoluble, light protecting pigments, namely finely dispersed, preferably, nano metal oxides or salts can also be considered for this task. Exemplary suitable metal oxides are particularly zinc oxide and titanium oxide and also oxides of iron, zirconium, silicon, manganese, aluminum and cerium as well as their mixtures. Silicates (talc), barium sulfate or zinc stearate can be added as salts. The oxides and salts are already used in the form of pigments for skin care and skin protecting emulsions and decorative cosmetics. Here, the particles should have a mean diameter of less than 100 nm, preferably between 5 and 50 nm and especially between 15 and 30 nm. They can be spherical, however elliptical or other shaped particles can also be used. The pigments can also be surface treated, i.e. hydrophilized or hydrophobized. Typical examples are coated titanium dioxides, such as, for example Titandioxid T 805 (Degussa) or Eusolex® T2000 (Merck). Hydrophobic coating agents preferably include silicones and among them specifically trialkoxyoctylsilanes or Simethicones. Micronized zinc oxide is preferably used. Further suitable UV light protection filters may be found in the review by P. Finkel in SöFW-Journal, Volume 122 (1996), p. 543.
The UV absorbers are normally used in amounts of 0.01 wt. % to 5 wt. %, preferably from 0.03 wt. % to 1 wt. %.
The inventive compositions can be obtained by the person skilled in the art according to standard techniques for manufacturing conditioning agents. The agents can be obtained by directly mixing their raw materials, optionally by means of high shear mixing equipment. For liquid formulations, the recommended procedure is to melt the optionally present softening components and to subsequently disperse the melt in a solvent, preferably water. The inventively utilizable silicon-containing compounds can be integrated into the conditioning agent by a simple mixing procedure.
The following examples are intended to exemplify the invention without limiting it in any way.

EXAMPLE 1

Preparation and General Information

Finish:

Bleached cotton cloth 1.1.10 (cotton) was used as the textile to be finished and was dry ironed smooth beforehand. For treatment, three test samples of dimensions 50×25 mm (in total 50×75 mm) were cut. The test sample (50×75 mm) in a crystallization dish was sprayed twice with a commercial spray adaptor, corresponding to an application of 0.023 g/cm².
Treatment with an Electric Iron:
The wet test sample was ironed dry for 10 seconds with an electric iron with the setting III. After cooling the test sample, it was cut up into three identical 50×25 mm samples and the crease recovery angle was determined.
Test Procedure
The crease recovery angle tester functions in accordance with the requirements of BS EN 22313, ISO 2313, M&S P22 and AATCC test method 66. It consists of two units. The first device consists of two rectangular weighted blocks that due to their weight crease the fabric. The second unit is the actual measurement equipment, with which the crease recovery angle is determined.
Load
The test sample (50×25 mm) is held together at each end by a plastic peg. Not more than 5 mm material may be gripped. The crease is produced by the load of a flat weighted block having a defined weight of 19.63 N (2 kg) for a period of 5 minutes.
Measuring the Crease Recovery
Using the supplied steel tweezers, the creased material sample is carefully placed into the clamp. After fixing it in position, the material is also clamped into the upper clamping jaw. The vertical position serves as the reference point. When the creased material touches this point by turning the angle wheel, the angle is read on the angle wheel.
The measurement is made 5 minutes after removing the weight from the wheel or after the crease formation. In general, the greater the crease recovery angle, the better is the anti-crease behavior of the creased material sample.

EXAMPLE 3

Comparison with Additional Commercial Products

Experimental: The Treatment Procedure Consisting of Fabric Treatment, Ironing and Washing Cycle was Repeated 4 Times.

3.1 Fabric Treatment:
Bleached cotton cloth 1.1.10 (cotton) was used as the textile to be finished and was cut up into four 20×120 cm test samples per treatment. Creases were produced by washing the fabric samples in a domestic washing machine (with H₂O only) and hanging them up in a climatized room for 24 hours. The horizontal test samples were sprayed as homogeneously as possible with 10 sprays of a commercial spray adaptor. The applied quantity corresponded to 0.16 g/cm².
3.2 Ironing Test:
A commercial steam iron, Professional Laser from the Rowenta Company, from a home made automatic ironing apparatus, 67 cm wide, was drawn over the fabric. The speed was 53.3 mm/s (=3200 mm/min). The temperature of the iron was set to step III. The iron was weighed down with 2940 g of metal pellets. As the sliding surface of the iron was 23.5 cm long and had a maximum width of 12 cm, and the appliance, at the beginning and end of the measurement still laid on the fabric, there remained an approximately 20 cm long and 12 cm wide area on the fabric for the evaluation of the measurement data, for which a total of 400 measurement points (measurement values 300-700) from 1000 were used to calculate the mean value.
3.3 Procedure for the Ironing Test and Evaluation:
To minimize possible influences from moisture on the lower surface of the iron on the ironing force, the tests were subdivided into two measurement series. For each formulation, 5 fabric strips were each ironed 4 times with the added weight of 2940 g. Each of the first ironing passages was not included in the subsequent evaluation. Before each measurement the iron was heated until the indicator light switched itself off. During the measurement run the plug was pulled out in order to avoid the resistance of the electrical cord. Prior to each new formulation, the iron was cleaned with a citric acid solution (3%), with ethanol and with distilled water. A strip of fabric of each formulation was used for a preliminary ironing pass in order to warm up the ironing overlay and to eliminate possible residues on the iron.
During ironing any disappearance of the crease was observed visually after each pass.
3.4 Wash Cycle Test Conditions


	Program:	40° C. whites/coloreds program
	Wash cycles:	1
	Load:	3.5 kg (test cloths + clean washing)
	Dosage:	109 g PNW + 36 ml Vernel (Wild Rose)

The test samples were taken wet from the washing machine, hung up on a washstand and dried in a climatized room for 24 hours.
3.5 Anti-Creasing Test According to AATCC 124
The creased test samples were visually evaluated and marked (1-5) against reference standards according to AATCC 124. The reference standard marked 1 contains the most creases. 5 is completely free of creases. The evaluation was carried out by 8 panellists. An average value was calculated from 8 different test values. Three test samples were treated with each product, such that in total 8×3 evaluation measurements were made per product.

Anti-Crease Test According to AATCC 124
To determine the initial degree of creasing and thus a quantitative evaluation of the results, the creased test samples were also evaluated prior to the spray treatment according to MTCC 124. 7 different panelists took part in the evaluation, such that the evaluation consisted of 7×3 notes per product.
Spray Treatment:
The horizontal test samples were sprayed as homogeneously as possible with 5 sprays of a commercial spray adaptor of the old Perla spray bottle from a distance of 25 cm. The applied quantity corresponded to 0.08 g/cm².
Smoothing
Directly after the spray treatment, the treated test sample was straightened out and smoothed by hand in each horizontal and vertical direction twice (see diagram).
Drying:
The treated test samples were hung up on a washstand to dry in a climatized room for 30 minutes.
Anti-Crease Test According to AATCC 124;
The treated test samples were visually evaluated and marked (1-5) against reference standards according to AATCC 124.
The reference standard marked 1 contains the most creases. 5 is completely free of creases. Marks of <1 and marks to the first decimal place may also be given.
The evaluation was carried out by 7 panelists. An average value was calculated from 7 different test values. Three test samples were treated with each product, such that in total 7×3 evaluation measurements were made per product.
