Liquid laundry detergent is compared with the washing powder that accounts for whole cloth-washing detergents market significant proportion has many advantages.For dissolubility washing assistant a little less than runny moisture surface activating agent inner suspension, as tripoly phosphate sodium STPP, or the needs of insoluble washing assistant such as zeolite impel development structure type tensio-active agent (structured surfactants).These are pseudo-plasticity compositions, and works wherein (structurant) is a kind of tensio-active agent or a kind of tensio-active agent/water lyophily intermediate phase (lyotropic mesophase).
The introducing that contains the concentrated detergent powder of higher concentration active ingredient than traditional washing powder has had the trend of competing with the liquid laundry agent.Need denseer liquid laundry agent to satisfy this competition on the market, particularly need to contain the dense aqueous surfactant compositions of the builder salt of dissolved or suspension.The electrolytical adding of a large amount of tensio-active agents and/or dissolved may impel the flocculation that produces high viscosity and/or unsettled structure-type tensio-active agent.
Unacceptable solvent on the environment for use need solve the problem of the water-insoluble or weak dissolubility agricultural chemicals that suspends with new method in liquid medium.The structure-type surfactant system has been represented a kind of like this method.Yet the throwing out of this system connection has seriously limited the exploitation of proper product with the crystal growth of suspended solids.
When the preparation dye bath, perhaps during printing ink, those dyestuff or pigment water-insoluble or weak dissolubility also need to be suspended in runny the thicking liquid to avoid re-using fine powder.
In the presence of polyelectrolyte, the trend that surfactant structure produces flocculation or generation decomposition has hindered the trial in the structure-type tensio-active agent with dyestuff and pigment suspension, described polyelectrolyte usually just is added into pigment before grinding, perhaps play the grinding aid effect.
Softener, toiletry and pharmaceutical preparation also often need prepare the stable suspension of in runny water-bearing media dispersed solid or liquid.This water-bearing media can require the ionogen of high density, and tensio-active agent or both perhaps mix polyelectrolyte.
Oil drilling slurry is to be used for lubricated drill bit and the breaking up rock that bores is transported to the face of land from drill bit.Find that the structure-type tensio-active agent can be used for preparing required rheology and solid suspension powder.This mud needs to tolerate very high electrolyte concentration, for example when salt deposit is passed in boring.This mud contains weighting agent (weighting agent) usually, and as barite, calcite or rhombohedral iron ore are beneficial to get into darker place.Yet getting into final stage, these mud contained usually the solubility weighting agent for example the single fluid of calcium chloride or Calcium Bromide replace.The ionogen of these dissolved alkaline-earth metal is to the high flocculation of most of surfactant structure deposits yields.
Pressing the weight of water and tensio-active agent and calculate, is 30% or more when (weight) at surfactant concentration, and the trend of most of tensio-active agents formation thickness intermediate phase had once limited the ability of enriching liquid detergent or other surfactant systems.Intermediate phase, or mesomorphic phase, be expression than solid low but than typical liquid high ordinal number arranged, such as one dimension or two dimension, partial 3-D.
Many tensio-active agents up to about 30% form micellar solution (L
1-phase), wherein tensio-active agent is dispersed in the water with micella, and they are aggregates of surfactant molecule, to such an extent as to can't see them with opticmicroscope very for a short time.
Micellar solution looks the same many purposes that have with real solution.Many detergent surfactants of about 30% form a kind of M-phase, and it is a kind of liquid crystal with hexagonal symmetry, and usually are a kind of fixed ceroidlike material.This product is difficult for flowing, and can not be used as liquid detergent significantly.At higher concentration, as surpassing 50%(weight), some concentration range is as mutually more runny with formation one below 80% 60% or more usually, the G-phase.
G-is the normal runny phase of non newtonian (shear-thinning) mutually, but typically has viscosity, flow characteristics and muddiness, and the oyster white phenomenon does not attract the human consumer like this, is not suitable for directly using as for example cloth-washing detergent.Attempt in early days solid suspension is failed to succeed at typical G-mutually, the product of producing is difficult for flowing.The flowed G-that existing report has a dilution in the wide relatively d-gap suspended solids of being on good terms is made runny suspension.
Under the situation of higher concentration, as be higher than about 70% or 80%, most tensio-active agents form a hydration solid.Particularly some formation of nonionogenic tenside contains the water droplet (L of dispersive micellar size
2-phase) liquid phase.L
2-find mutually to be not suitable for being used as liquid detergent, because it is difficult for disperseing in water, and tangible gelatigenous tendency.They are suspended solids not.Other can observedly comprise viscosity isotropic (V) phase mutually, and it is a fixed, has glassy.
At polarizing microscope, electron microscope and x-ray diffraction or scattering of neutrons are by its outward appearance, and the bound energy of rheology and structure (texture) is discerned different phases.
The relevant different mutually related following term of discussing in specification sheets need make an explanation or define: " optical isotropy " tensio-active agent usually and be not inclined to the polarization plane of Plane of rotation polarized light.If a sample places between two optical flat polarization things, the plane of polarization of this two material is orthogonal, irradiate light is on a plain film, and when observing by the another one plain film, the sample of optical isotropy tensio-active agent manifests basically unlike brighter around them.It is brighter basically that optically anisotropic substance manifests.Adopt microscope to observe by the polarizer that crosses one another, the optical anisotropy intermediate phase typically shows characteristic structure (characteristic textures).And that optical isotropy shows mutually usually is dark, is essentially the continuous spectrum of atypism.
" Newtonian liquid " has the viscosity that keeps stable under the different shear rate shape.The purpose of this specification sheets is, if in shearing rate during up to 1000/ second, the essentially no variation person of its viscosity is regarded as Newtonian liquid.
L
1Be mobile mutually, optical isotropy, the typical Newtonian liquid of display structure not under polarizing microscope.Only under very high very big multiple, could arrive the structure of this phase, under x-ray diffraction under the very little angle or scattering of neutrons normal circumstances, still see the broad peak of a single typical liquid structure, L with electron microscopic observation
1The viscosity of phase is low usually, but also can significantly rise in limited time when concentration reaches going up of this phase.
L
1-be single mutually, thermodynamically stable phase, it can be considered to the aqueous solution, and wherein solute molecule is combined into spheric, bar-shaped or disc-shaped micelle, their diameter generally is about 4-10 millimicron (nanometers).
" stratiform " is to comprise a large amount of be arranged in parallel or by the phase of the separated double-layer surface-active agent of liquid medium mutually.They comprise that promptly solid-state phase also comprises typical liquid crystalline G-phase.G-is typical runny non newtonian, anisotropic product mutually.They are typical thickness outward appearance, have the oyster white material of distinctive " greasy shape " outward appearance when mobile.They form distinctive structure under polarizing microscope, and (freeze fractured) sample of observing its freezing crushing under the Electronic Speculum has a layer sample outward appearance.X-ray diffraction or scattering of neutrons illustrate a stratiform structure equally, its main peak typically 4 and 10nm between, be generally 5-6nm.When at the twice of main peak Q value or higher integral multiple, higher order peak (order peaks) appears.Q is momentum transfer vector (momentum transfer vector), and when lamellar phase, it relates to the repetition interval d that draws through following formula.
Q= (2nπ)/(d)
Wherein, n is peak order (order of peak)
G-can comprise the state and the spherocrystal that becomes with a large amount of homocentric sphere hull shapes of the parallel lamella of the main body that constitutes above-mentioned typical G-phase with several multi-form existence mutually, and each spherocrystal all is double-deck tensio-active agent.It is the composition of former structure attitude at least in part that term in this specification sheets " stratiform " will apply to.Back one type of prevailing at least this transparent composition is referred to as " spherocrystal shape " thing, and the external phase in wherein back one type is a kind of isotropic basically solution that contains the dispersive spherocrystal.The diameter of spherocrystal typically between 0.1 to 50 micron, therefore is different from micella basically.Different with micellar solution, spherocrystal shape composition is the heterogeneous system that comprises at least two phases basically.They are anisotropic, non newtonian.When closely knit and stable, spherocrystal has good solid suspension performance.The composition that contains the external phase of non-spherocrystal shape circular layer contains some spherocrystal usually, but does not have dispersible solid or other phase times, and it is typical transparence.And be referred to as " the combined thing of G-".G-is write as L α-phase mutually in the literature sometimes.
M-is typical fixed mutually, the product of anisotropic class ceraceous sample.Under polarizing microscope, has distinctive structure, have the sexangle diffraction pattern with x-ray diffraction, scattering of neutrons contains a main peak, and the value corresponding to recurrence interval (repeat spacing) is between the 4-10nm usually, higher order peak is arranged sometimes, and its first peak Q value is 3 of main peak Q value
0.5Doubly.Bimodal Q value subsequently with main peak.M-is write as the H-phase mutually in the literature sometimes.
L
2-phase and L
1Mutually opposite, be included in the micellar solution of the water in the successive liquid surfactant medium.With L
1The same mutually, they are isotropic and newton.
Viscosity isotropy or " VI " they are typical fixed mutually, non newtonian, optically isotropic, and be that the typical case is transparent at least in pure.VI is the diffraction pattern of cubic symmetry mutually when x-ray diffraction, and scattering of neutrons is 2 of main peak Q value

0.5Doubly locate to occur a main peak and higher order peak.
Reported increase, after micellar phase, occurred a kind of cubes mesomorphic phase immediately along with the concentration of room temperature lower surface promoting agent.Someone proposes this VI phase, is called I sometimes
1Phase may be from the heap of the micella in the cubic(al)grating (may be sphere).Further increase surfactant concentrations under the room temperature and usually cause producing hexagon phase (M
2), it produces after lamellar phase (G).When I occurring
1Phase time mostly just can be observed in a narrow concentration range, is typically just at L
2Mutually on the concentration range of Xing Chenging.This is to be made of the little surfactant aggregates closely in the continuum of water mutually for the position indicating of this VI in phasor.
According to the report I

Observe or proposed several other intermediate phase, comprised the nematic phase that contains wired spline structure.
Term " structure-type tensio-active agent " is used for representing runny, the non newtonian composition of flow-like, and it relies on the existence of tensio-active agent intermediate phase or solid phase, has the ability of physical property ground suspended solids, and these solid particulates are dispersed in the solvent phase.The latter is ionogen water (aqueous eletrolyte phase) normally.Tensio-active agent exists with the closely knit spherocrystal form that is dispersed in aqueous phase mutually usually.Alternative, continuous net-shaped moisture distribution of the lamellar phase of the flowability of skim or a pair of and lamellar phase also can exist.Sexangle usually is not enough to flow form the basis of body structure surface active agent mutually, but can exist exceptionally.Fail to observe and cube can sufficiently flow mutually.L
1Or L
2Mutually itself can not structurizing, they lack suspension property, but can exist with for example external phase form, and in its laminate or spherocrystal were dispersed in mutually, it also can exist by disperse phase, for example is dispersed in a continuous stratiform or the isotropic phase.
Body structure surface active agent is different from the microemulsion of thermodynamic stable system.Microemulsion is a kind of micellar solution (L basically
1Phase), wherein hydroaropic substance is wrapped among the micella.
The body structure surface active agent also colloidal system with dynamic stabilization is different.The particle of disperse phase very little (as<1 micron) is enough to be subjected to the influence of pedesis in colloidal system.Therefore to keep through the frequent stirring of interior phase disperseing.On the contrary, it mechanically is stable that body structure surface active agent shows, and its particle does not move in surfactant structure.When this system remains static, can monitor not motion of particles suspended, but be enough to break this structure to relevant shearing stress with inclining, this product is flowed.
Just when the opposite reference of describing herein viscosity viscosity apparatus, 100 rev/mins and 20 ℃ of viscosity that determine with the Brookfield4 axle.About 21/ second of this corresponding shearing rate.This is the sign of quasi-viscous liquid easy mobility.
Often need be under surpassing its deliquescent situation with solid or liquid dispersion in water-based.This dispersion system should easily flow ideally and after leaving standstill for a long time, also keep disperseing uniformly.
Have been found that structure attitude tensio-active agent as suspension matrix than traditional method dispersion system, colloid for example, the use of the use of microemulsion or thickening material or mineral substance works etc. has many advantages.
The example of application structure surfactant system comprises the scouring agent that contains solid detergent, contains the hard surface cleaner of abrasive grains, toiletry, dyestuff and pigment suspension, agricultural-chemical suspension liquid, drilling mud and lubricant.Water sample body structure surface active agent composition, for example liquid laundry agent, makeup, and agricultural chemicals, dyestuff and other solid suspension matrix usually require to contain a large amount of tensio-active agents and/or ionogen.
Tensio-active agent exists with the spherocrystal form usually.Spherocrystal has tangible tendency of flocculation, particularly when polyelectrolyte concentration.This tendency can cause unstable and/or very high viscosity.
Also observed same effect with other body structure surface systems.The objective of the invention is to reduce flocculation and/or viscosity, and/or increase this heavy-gravity, stability easily flocculation and/or the unstable structure tensio-active agent.
The tensio-active agent that often produces the specific type of instability or flocculation problems is the one group of tensio-active agent that comprises fabric regulator.They typically have two groups of C
15-C
25Alkyl or kiki alkenyl group (being generally the Tallow, beef group), and generally be cationic or amphoteric.
One special problem is at the high-load washing assistant of composition acquisition that contains effective combinations-of surfactants that is used for washing synthetic textiles.Have been found that high-load solid detergent, for example tripoly phosphate sodium STPP or zeolite can cause the high viscosity that can not make us accepting.
The stability of tensio-active agent or flocculation problems are not always contained the electrolytical composition restriction of excess.When attempting to comprise soluble polymer in the body structure surface active agent system, they also produce this class problem.For example these polymkeric substance can be desirable as the soil suspension agent, grinds auxiliary, and film shaped dose of paint or enamelled are perhaps to prevent the growth of xln in agricultural-chemical suspension liquid.
Use the washing composition of zeolite builders to also have other problem, promptly they to the effect of removing dust than the washing composition of poly-phosphate washing assistant come poor.Noticed among the EP-A-0419264 that the effect as the zeolite of washing assistant can increase in the presence of some coassist agent widely, this coassist agent is some amino phosphonates do that obtains with the oligopolymer form usually (aminophosphinates).Unfortunately, fail to find the quantity of the amino phosphonates do with meaning (aminophosphinates) that can in not causing the zeolite builders liquid detergent that is separated, use.
Body structure surface active agent record to some extent in a large amount of open source literatures, they comprise GB2123846, GB215380, EP-A-0452106 and EP-A-0530708

Though in the overwhelming majority's example, will be present in this structure in the following described prescription, and be not enough to and stably solid to be remained in the suspension.
EP-A-0388239 discloses a kind of body structure surface active agent in formulation of pesticide.
EP-A-0430602 described in drilling mud or the liquid of other functions in the body structure surface active agent that uses.
EP-A-0472089 has described the body structure surface active agent that uses in dyestuff and pigment suspension.
EP-0301883 has described certain polymkeric substance and has lowered the application of agent in liquid cleaner as viscosity.Yet the polymkeric substance of describing in above-mentioned open source literature is ineffective so especially.As a result, disclose a large amount of patents relevant with the more specifically polymkeric substance of the reduction viscosity effect of attempting to provide higher (referring to EP-A-0346933, EP-A-0346994, EP-A-0346995, EP-A-0415698, EP-1-0458599, GB-2237813, WO91/05844, WO91/05845, WO91/06622, WO91/06623, WO91/08280, WO91/08281, WO91/09102, WO91/09107, WO91/09108.WO91/09109 and WO91/09932).It is said that these polymkeric substance of certain class are that deflocculation agent causes the preparation that the infiltration of spherocrystal is shunk with other.These polymkeric substance are relatively costly products, and the washing effect Relative Contribution to this prescription is very little like this.They typically have pectination, and the skeleton of a hydrophilic polymer is arranged, and have a large amount of hydrophilic side chains on the skeleton, and are perhaps opposite.
We find that some tensio-active agent has good effect in the flocculation spherocrystal of deflocculate or other surfactant systems now, these tensio-active agents form micella, and in the ionogen aqueous phase solubilized of body structure surface active agent 10%(weight at least), they can reduce the viscosity of heavy-gravity system too and/or stablize unsettled body structure surface active agent prescription.They have surfactivity in addition, also prescription are had the auxiliary agent effect sometimes.Stablizer and/or deflocculation agent that the present invention adopts are to have C
4-C
25Hydrophobic grouping, for example tensio-active agent of alkyl or alkenyl group, particularly C
6-C
20Alkyl, with a hydrophilic radical, this hydrophilic radical is the polymkeric substance of hydrophilic monomer typically, perhaps particularly a kind of substituting group polymer of monomers with hydrophile function, or a kind of polymer of monomers with chain that connects hydrophilic substituent, this monomer is to be connected in described hydrophobic group one end.The average quality of described hydrophilic radical is greater than 300amu, is generally greater than 500, and preferably greater than 900amu, the best is greater than 1000amu.Hydrophilic radical normally contains more than 4, the polymkeric substance of general about 6 to 8 monomer unit, and this depends on the recurrence interval of monomeric size and surfactant structure.The tensio-active agent that shows these features is referred to as " described stablizer " in this article.The character and the concentration that depend on the ionogen phase as the selection of the tensio-active agent of described stablizer.
The ionogen of common type is that polyvalent is cationic in scouring agent, for example tripoly phosphate sodium STPP or Potassium tripolyphosphate, perhaps Tripotassium Citrate or Trisodium Citrate, according to it dissolving and help the ability of washing, usually being used to needs in the prescription of polyelectrolyte concentration.
At Trisodium Citrate, or in other polyvalent cation electrolyte solutions, described stablizer preferred example is an alkanol, or the polyelectrolyte of alkylthio terminal, polyacrylic ester for example, polymethacrylate, or poly-crotonate (polycrotonate).
Known water-soluble polyacrylate with alkanol or mercaptan chain terminator is used for coating, pasted paper and non-woven fabrics textile industry field are (for example, JP04081405, JP01038405 and JP62085089) and be used for (for example JP62280203 and JP1947384) in the middle of the manufacturing of latex.The calcium salt of same polymer is also put down in writing as carbon black and ferric oxide the dispersion agent in water in JP01310730.
We have found that polycarboxylate with 4 above hydrophilic monomer units or other polyelectrolyte at deflocculate, reduce viscosity, stablely contain the electrolytical liquid detergent of multivalent anions aspect and have better effect than aforesaid polymkeric substance.The chain quilt of described monomer unit, for example C
6-C
25Fatty alcohol, mercaptan or amine cover, perhaps by C
6-C
25Alkyl carboxylate's (ester), phosphoric acid salt, hypophosphite, or phosphorous acid ester group (hereinafter claim " described polyelectrolyte stablizer) covers.Described polyelectrolyte stablizer also strengthens the use properties of liquid detergent.
The another kind of polyelectrolyte that uses as described stablizer in the multivalent anions ionogen is an alkyl oxide polycarboxylate product, and it is by to having C
8-C
25Alkyl and polyoxyethylene chain as polyethoxylated alcohols (polyethoxylated alcohol), add in the compound as methylene-succinic acid, toxilic acid, or unsaturation carboxylic acid or their salt such as fumaric acid, and the employing free-radical initiator is made.This product typically has one, and preferably a plurality of ethoxy groups and one are preferably a plurality of 1,2-two propyloics (1,2-dicarboxy ethyl groups).
In EP0129328 and its English Patent GB9314277.6 that awaits the reply, this alkyl oxide polycarboxylate has been described.
The example of another described stablizer is the poly-sulfo-maleate (polysulphomaleate) that alkyl covers.
Another kind effective described stablizer in the multivalent anions ionogen is the alkylpolyglycosides (alkyl polyglycoside) with high relatively polymerization degree.We have found that alkylpolyglycosides is reducing viscosity, the stable aspect of improving dense water sample body structure surface active agent system is extremely effective, and subsidiary strengthening the property.
The described stablizer that another kind is used in the multivalent anions ionogen is sugar ester or glycolipid.(sucrose ester) is invalid for sucrose ester, but all effective as the contour oligomeric sugar ester of palmitinic acid maltose pentose ester (maltopentaose palmitate).The ester that preferably has 4 above glucosides groups.Sugar ester for the effect of assembling liposome referring to J.Colloid and Interface Sci.Vol152 No.2 Sept.1992.
We also find when the alkyl ethoxy compound generally plays the stablizer function of this system in multivalent anions type ionogen enough stable.
Second type ionogen is the polyvalent cation type, as calcium chloride.It can be as the solubility weight agent (weighting agent) in the drilling mud if desired.Polycarboxylate generally is not enough to dissolving and uses as stablizer in the presence of the high density polyvalent cation.Polysulfonate, as alkyl polyvinylsulfonic acid salt or alkyl poly-(2-acrylamide-2-methyl propane sulfonic acid salt) is preferred, contain more than 6, the alkyl polyethoxylated of 20 vinyloxy group units (ethylene oxy units) is also effective.
The ionogen of the third type is included in the monovalent cation and the negatively charged ion of high density, as Repone K.The polyelectrolyte solvability is bad in this system, but good as described stabilizer function as the senior poly-b-oxide of the poly-b-oxide of 7-80 mole alkyl.
Even also can cause the ionogen of the another kind of type of serious flocculation problems under low relatively concentration is conventional polyelectrolyte, as bitter edible plant sulfonic acid and formaldehyde multipolymer, (uncapped) polyacrylate of carboxymethyl cellulose or non-covering or polymaleic acid salt.In the body structure surface active agent system, usually require the typical non-micellar polymkeric substance that forms.Require to grind to form very thin powder as pigment suspension, usually a small amount of polyelectrolyte is added as grinding auxiliary, this body structure surface active agent produces serious flocculation as a result.
We have found that common effect is rather good aspect the deflocculate of pure ethoxyquin compound in this system, and since the existence of the soluble polymer of other types to present in unstable or the full-bodied system effect also good.
We also further find in the presence of described stablizer, will high-load relatively amino phosphonates do (aminophosphinates) adding liquid detergent compositions in and do not produce any unsettled situation.
Our also further discovery deflocculation agent such as stablizer as described constantly adds unsettledly, or in the heavy-gravity prescription time, its viscosity begins to descend, until obtain a kind of stable liquid product.If add the deflocculation agent of volume, its viscosity rises to maximum before descending once more, along with further adding produces the combined thing of G-of a transparent high workability, and has good suspension characteristic.Further adding can produce-transparent L
1-phase is unstructuredness significantly.The potential value of this product is to be applied to limpid washing composition or the shampoo that those do not need the solid suspension characteristic.
We have found by mixing high-load relatively nonionic surfactant and water soluble detergency promoter, potassium metaphosphate for example, combinations such as Potassium tripolyphosphate particularly can obtain high-load washing assistant and to the high-efficient washing effect of synthetic textiles with being used in combination as tripoly phosphate sodium STPP suspension washing assistant.
In this system, it requires the ionogen and a high proportion of nonionogenic tenside, the particularly nonionogenic tenside of polyethoxylated type of high density.We find that also this forms under normal circumstances the very novel uneven body structure surface active agent system of heavy-gravity.This new system comprises an isotropy (isotropic) phase, and we think that it is a kind of as L
2The rich tensio-active agent phase of-phase, it is dispersed in and may is or may comprises that we think L
1In the external phase of the isotropic phase of-phase,, be a kind of anisotropy phase perhaps as lamellar phase in some cases.In some cases, disperse phase wherein can comprise a L in a continuous lamellar phase
2-phase.In addition, we do not illustrate L
2L mutually
1The phase dispersive forms.
We find that such new texture surfactant system can be stable and be formed with the solid suspension system of usefulness with described stablizer.

Water medium
Some tensio-active agent particularly can be in water as oil soluble surfactants such as Isopropylamine alkylbenzene sulfonates, even form flocculation under no electrolytical state, structural system.In these examples, water medium can be made up of water basically.Yet most tensio-active agent particularly only produces flocculation in the electrolyte solution of high density in the presence of the solubility ionogen.
The present invention's composition typically contains high-load solubility and removes to dissolve the tensio-active agent ionogen.Be typically, by height to the electrolytical concentration of weight solubility of saturated prescription greater than 10%, as greater than 14%, 15%(weight particularly).For example, the enough electrolytical concentration of dissolved can be between 16% to 40%.Can over-saturation there be excessive formation suspended solids part in the ionogen solid.
Ionogen can typically be a kind of of following four kinds of main types:
(ⅰ) multivalent anions salt: potassium metaphosphate preferably wherein, Potassium tripolyphosphate and Trisodium Citrate or potassium.
This ionogen generally is preferred for washing composition, and the prescription that is used for agricultural chemicals and pigment and dye bath.
(ⅱ) polyvalent cation salt: preferred salt is calcium chloride and Calcium Bromide.Other salt comprises fontanel zinc, bariumchloride and nitrocalcite.Preferably agent is used for drilling fluid to these ionogen as solubility weight.This salt particularly suitable complete with closely knit solution (completion and packing fluid).
(ⅲ) have the monovalent cation salt of univalent anion: these salt comprise fontanel choline metal or fontanel amine, Repone K for example, sodium-chlor, potassiumiodide, Sodium Bromide, or brometo de amonio, perhaps citric acid alkali metal or ammonium salt.Sodium-chlor is specially adapted to drilling fluid, and this liquid is used to bore the stratum through tolerance salt.
(ⅳ) polyelectrolyte: it comprises the non-micellar polyelectrolyte of formation, for example unlapped polyacrylate, polymaleic acid salt or other polycarboxylates, sulfonic acid lignin or bitter edible plant sulfonic acid and formaldehyde multipolymer.This polyelectrolyte has extra high throwing out to body structure surface active agent, even also is like this when lower concentration.With described polyelectrolyte stablizer or alkyl polyethoxylated, or alkylpolyglycosides can this class ionogen of deflocculate.
In order to form the structure that can support solid matter and/or the flocculation that causes body structure surface active agent, the amount of general relevant with its solubility tensio-active agent is bigger, and required ionogen is then fewer.Usually the preferred ionogen of selecting to help the composition function, and because economic reasons is usually used cheap ionogen.The electrolytical amount that adds is by the quantity decision of the performance that requires to provide suitable (for example scourability of sanitising agent).Obtain ideal viscosity and stability with described stablizer then.
Yet electrolyte concentration depends on desired structure type in other respects, viscosity and consider Time, Cost And Performance.Usually we select to form the spherocrystal system, as us at GB-A-2,153,380 and EP-A-0530708 described in, purpose is the balance that obtains the satisfaction of suspended solids between flowability and high efficiency.This structure can not be obtained usually, can unless exist at a certain amount of ionogen.
Except cost issues, select ionogen also may depend on the purposes that suspension is desired to think.Laundry product often contains the solubility builder salt.Composition can contain auxiliary or synergistic matter as ionogen or the part as ionogen.The ionogen of selecting should chemically be complementary with the desire suspended matter.The typical ionogen of the present invention's use comprises basic metal, alkaline-earth metal, and ammonium or amide, they comprise muriate, bromide, iodide, fluorochemical, orthophosphoric acid salt, condensed phosphate, potassium metaphosphate for example, tripoly phosphate sodium STPP, phosphonate (phosphonates), as the acetyl diphosphonate, or amino three (methylene phosphonic acid salt), ethene diamino four (methylene phosphonic acid salt) and divinyl triammonium five (methylene phosphonic acid salt), vitriol, supercarbonate, carbonate, borate, nitrate, oxymuriate, chromic salt, formate, acetate, oxalate, Citrate trianion, lactic acid salt, tartrate, silicate, hypochlorite if desired, is regulated the stability that pH value improves suspended solids or dispersion liquid, reduce toxicity, bronsted lowry acids and bases bronsted lowry, for example hydrochloric acid, sulfuric acid, phosphoric acid or acetate, or sodium hydroxide, potassium, ammonium or calcium or alkaline silicate.
Form the ionogen of infusible precipitate with tensio-active agent, perhaps may form big crystallization, as preferably do not adopt greater than 1mm crystalline ionogen when leaving standstill.The concentration of above-mentioned sodium sulfate for example, the saturation concentration that approaches 20 ℃ of compositions is unfavorable.The vitriol of saturation concentration when therefore our composition selected does not contain above its 20 ℃ particularly contains the composition of the vitriol of saturation concentration when being lower than its 15 ℃.
Because expense, we like adopting sodium salt as ionogen, although also usually need exist sylvite to obtain low viscosity and polyelectrolyte concentration sometimes in electrolytic solution.Lithium and cesium salt were also successfully attempted, but they can not use in commercial formulation.Calcium salt such as calcium chloride and Calcium Bromide etc. have been used to drilling fluid system, and their relative high-density help providing the weight of mud.Other also can use as bases such as organic basess, and for example low-alkylamine and alkanolamine comprise monoethanolamine, trolamine and Isopropylamine.
Except that substituting the solubility ionogen with water medium, also may contain the flocculation of solvable amount or remove to stablize the nonelectrolyte polymkeric substance, its quantity can be flocculated and/or be removed to stablize described tensio-active agent.Comprise polyvinyl alcohol or polyoxyethylene glycol among the embodiment.
Stablizer
We believe that described stablizer plays the flocculation inhibitor at least basically.We observe especially, and the adding stablizer has fairly obvious benefit in the surfactant system of height flocculation.
Do not have this stablizer, usually be difficult to obtain a composition that the keying action of rheological properties and wash characteristics is arranged.Composition is not that too sticking to be difficult for toppling over and to hang cup be exactly unstable, is divided into two-layer or multilayer.Along with tensio-active agent and/or help the increase of washing composition total concn, difficulty also strengthens.Commercial pressure for denseer liquid detergent demand brings a specific question for manufacturers, adopts described stablizer to solve.
Preferably reconciliation statement surface-active agent and/or electrolytical concentration obtain a kind of composition, and when adding described stablizer, said composition is in room temperature, leave standstill when 0 ℃ or 40 ℃ or most preferably above-mentioned two kinds of temperature and do not produce precipitation in three months.Also can regulate the composition that concentration obtains a kind of shear stable, it is desirable to, be subjected under the normal shearing force, not increase the composition of viscosity basically.To such an extent as to might the option table surface-active agent and electrolytical concentration when not having described stablizer but under high viscosity, can obtain above-mentioned feature.Add stablizer then to reduce its viscosity.
According to the present invention, its composition should comprise the weight by total composition 0.005-20%() stablizer, be preferably 0.01-5%, preferably 0.05-2%.
When in the ionogen multivalent anions being arranged, as Trisodium Citrate, the hydrophilic segment of our preferred stabilizer has many carboxyls and/or hydroxyl, as alkyl oxide polycarboxylate particularly, alkylpolyglycosides, poly-dihydroxy acid amides (polyglycamide) and/or described polyelectrolyte stablizer.
When ionogen comprises polyvalent cation, the stablizer that we preferably use has many sulfonate, phosphoric acid salt, vitriol or phosphonate groups, polyvinyl sulfonate for example, alkyl gathers (2,2-acrylamido methyl propane sulfonic acid salt), sulfonated alkyl polyvinyl alcohol, poly-sulfonated alkyl polystyrene, alkyl polyethylene phosphoric acid salt, alkyl polyvinylphosphonic acid salt, or poly-(vinyl sulfonate) alkyl poly-alkoxylation thing.
When ionogen is the basic metal fontanelle compound, or identical monovalence system, alkylethoxylate preferably used, it preferably has more than 7 above oxyethyl groups, particularly surpasses 10, is typically to surpass 20, as 25-75, particularly 30-60, the best is a 40-55 oxyethyl group.
The present composition can contain one or more described stablizers.
The stablizer that the present invention uses is characterized in that it being the tensio-active agent with a hydrophilic segment and a hydrophobic part.Hydrophobic part mainly comprises at least a C
6-C
25Alkyl, or alkenyl, preferably single C
8-C
20Alkyl or alkenyl are as straight chained alkyl.Hydrophobic part optionally comprises aryl, alkaryl, cycloalkyl, branched-chain alkyl, polytrimethylene oxygen base (polypropylenoxy), or polybutylene oxygen base group.In some example, may or preferably use butyl group as hydrophobic part.Hydrophilic segment requires relatively large, preferably contains many hydrophilic functional groups, as hydroxyl, and carboxyl or sulfonate.
Have the not effect of alkylglycoside of one or two glycosides residue, and the alkylglycoside with the glycosides residue more than 7 or 7 has very strong effect, this fact shows the size of required hydrophilic segment.Extent of polymerization preferably greater than 1.3, and has the poly-glycosides that wide distribution contains a large amount of senior glycosides to be very useful greater than about 1.2 poly-glycosides (polyglycosides), and its effect increases along with the increase of the polymerization degree.Yet find basically by two glycosides the alkylpolyglycosides part relative nullity that three glycosides or four glycosides are formed.And the part of mainly being made up of seven glycosides is very effective, and this is just to compare with the most preferred embodiment of described polyelectrolyte stablizer in dense citrate solution.Equally, per molecule has the alkyl oxide polycarboxylate of 1 to 3 ethylene oxide residue and 2 to 3 carboxyls of average out to, is relative nullity, and have more than 3,8 above residues and more than 4 particularly, particularly the carboxylate salt of 8 above carboxyls is generally more effective.For example, it is very effective in citric acid solution to have 11 moles of b-oxides of 10 or 10 above carboxyls.
Glucose ester is generally invalid, but oligomeric sugar ester, as Fructus Hordei Germinatus pentose (malto pentaose), or senior oligose, as the ester of partially hydrolysed starch of great use.
In system, very effective as the senior b-oxide of 25% Repone K of 7-80 mole such as 20-50 mole b-oxide, but rudimentary b-oxide, such as 3 moles of oxide compound relative nullities.
Generally, the effect of polymeric tensio-active agent as if with depend on that tensio-active agent hydrophilic segment mean polymerisation degree is compared and depend on senior composition (for example have MMW, or greater than the polymkeric substance of tetramer) more greater than 100 hydrophilic group.
Have a kind of method can judge whether a kind of particular compound shows its necessary solvability, promptly measure its solvability in concentrating aqueous electrolyte liquid, preferred ionogen is the ionogen in the composition, or other ionogen identical with its chemical feature.
For example, as the liquid detergent of auxiliary agent or similar system, wherein ionogen at least mainly is made up of the multivalent anions compound with citric acid, and a kind of ionogen easily is a Tripotassium Citrate, as contains 15% weight and close to citric acid is full, as the solution of 16%-18%.The solvability of stablizer should be at least 10%, is preferably at least 2%, is preferably at least 3% again, is preferably in 5%(weight at least).For example, can do a test, in the 18% Tripotassium Citrate aqueous solution, add enough concentration, as greater than 30% the stablizer aqueous solution, to obtain 5%(weight in the whole solution) stablizer.
Be not subjected to the restriction of any theory, we believe stablizer hydrophobic part can with outer double-deck combination of spherocrystal, hydrophilic segment can the very big surface that is enough to by spherocrystal, prevents flocculation, as long as its enough dissolving in the water-based of circumference.
The feature of the key of stablizer of the present invention is that they are linear structure substantially, the normally essential such class tensio-active agent with the linear hydrophilic polymeric base that is covered by a hydrophobic group on the one end group.This is just in time opposite with the pectination of emphasizing about deflocculation in the prior art, and wherein hydrophilic bond has many hydrophobic side chains or opposite.The surfactant stabilisers that we believe the present invention is deflocculate more effectively, simultaneously composition all surfaces activity is had contribution.

The present composition can contain solid up to for example 80% suspension by composition total weight, is generally to reach 30%, as 10-25%.The character and the purposes of the combination of the use of determining measured in suspension.As in detergent composition, usually require to contain insoluble washing assistant, as the washing assistant of zeolite or a spot of solubility, as tripoly phosphate sodium STPP, it can be suspended in the body structure surface active agent matrix.
Surfactant system of the present invention also can be used for suspending: abrasive material, and as talcum, silicon, calcite, thick zeolite is as hard surface cleaner; Or agricultural chemicals, to obtain water-dispersion, contain the dumpable composition of water-insoluble agricultural chemicals, there is not the solvent of deleterious poisonous soil dust or hostile environment.They also are used to provide dyestuff, pigment, and medicine, the suspension of sterilant perhaps as drilling mud, contains suspension shale and/or weight agent such as sodium-chlor, calcite, barite, square aluminium ore or rhombohedral iron ore.
Their exfoliant that can be used to suspend comprise talcum, earth, polymeric beads, sawdust, silica, seed, Pericarppium arachidis hypogaeae or Lin Suanergai, pearlisers such as mica, the glyceroyl list-or two-hard acid ester salt, or the ethylene glycol list-or two-hard acid ester salt, natural oil is as Oleum Cocois, night paper spring (evening primrose) oil, peanut oil, meadow foam oil, Prunus amygdalus oil, Lipoval A, persic oil, perhaps jojoba oil, Synthetic Oil, as the polysiloxane grease, VITAMIN, anti-scurf agent is as, Zinc Omadine, the disulphide of selenium, albumen, tenderizer is as lanolin or sec.-propyl nutmeg acid esters, wax and sun-screening agent such as titanium dioxide and zinc oxide.
Washing assistant
Detergent composition of the present invention preferably contains the suspended particle of solubility washing assistant and/or solid detergent, to obtain a kind of synergic liquid detergent.It is a kind of by improving the compound that is used for the cosurfactant cleaning function of dissolved calcium and/or magnesium to use " washing assistant " to be meant herein.The also auxiliary alkalescence that keeps washings of general washing assistant.Typical washing assistant comprises sequestering agent and recombiner, as tripoly phosphate sodium STPP, potassium pyrophosphate, tertiary sodium phosphate, sodium ethylene diamine tetracetate, Trisodium Citrate or NTA nitrile triacetic acid sodium (Sodium nitrol-triacetate), ion-exchanger such as zeolite and throw out, as yellow soda ash and salt of wormwood, and other alkali such as water glass.Described stablizer has also had a effect to all washing assistants.Preferred washing assistant is zeolite and tripoly phosphate sodium STPP.The concentration of washing assistant can reach 50% of composition weight, as 15-30%.
PH
The composition dilute with water that uses as lotion is measured preferably alkalescence of its PH later, to obtain accounting for the solution of composition weight 1%, as 7-12, is more preferably 8-12, most preferably is 9-11.
Hydrotropic agent
The present composition can optionally contain a spot of hydrotropic agent, as sodium xylene sulfonate, and toluenesulfonic acid sodium salt or sodium isopropyl xanthate, its concentration is the as many as 5% of composition total weight, is preferably and is no more than 2%, as 0.1%-1%.Hydrotropic agent is attempted the failure surface active agent structures, so importantly do not want excessive use.Its main effect is the viscosity that reduces prescription, but may make prescription unstable too much.
Solvent
Except water, composition can contain solvent.Yet as hydrotropic agent, solvent is also attempted the structure of failure surface promoting agent.Yet also the formulation cost that they increase as molten growth substance does not but have the improvement of essence to scourability.Based on the reason of environment, do not need them, it is to be to provide solvent-free composition that the present invention has special value.Therefore what our solvent selected for use accounted for composition total weight is less than 6%, more preferably is less than 5%, most preferably less than 3%, particularly is less than 2%, more especially is less than 1%, as is less than 0.5, as mixable alcohol of this water or ethylene glycol.Though the composition that we adopt needs a spot of glycerine or propylene glycol sometimes, does not have solvent basically.Sometimes need ethanol, the about 3%(weight of its concentration as many as), as 1-20 to tart up.This concentration usually can be approved the destabilization that can't cause this system.
Polymkeric substance
The present composition can comprise various polymkeric substance.Particularly it may be combined with the polyelectrolyte of consumption, as polyethylene hydrochlorate or the polymaleic acid salt that also covers.This polymkeric substance can use, because they can reduce viscosity, and because have the effect that helps washing composition, can have protection against corrosion or antiscale activity.Unfortunately their also failure surface active agent structures can not add body structure surface active agent and don't go to stablize this system with effective dose.Found that heavy dose of relatively polyelectrolyte adding structure can be washed agent combines with described stablizer, does not produce and stablizes this structure.Can provide like this than only being the stable product that the low viscosity that reaches of stablizer requires.
Some examples of the polymkeric substance that contains in the prescription are precipitation agents, as Xylo-Mucine, and the anti-whipping agent of anti-whipping agent such as polysiloxane, enzyme stabilizers, as polyvinyl alcohol and polyvinylpyrrolidone, dispersion agent such as Sulfite lignin and sealing agent such as glue and resin.We find to grind auxiliary, are very useful as dimethyl bitter edible plant sodium sulfonate/formaldehyde condensation compound, and are the same with dyestuff or formulation of pesticide, and the solid that suspends in the composition needs to grind.
The amount that adds polymkeric substance is decided by the application target of this polymkeric substance.In some cases, can be for few to 0.01%(weight) even lower.Amount 0.1~10% commonly used is 0.2-5% particularly, as 0.5-2%(weight)

Except novel laundry detergent is provided, outside fabric conditioner and the flushing breast (scouring creams), stable structure tensio-active agent of the present invention can be used for makeup, comprises shampoo, liquid soap, emulsion, vanishing cream, face cream, ointment, sterilant, tooth powder and hemostatic drug.
This tensio-active agent is for dyestuff and condensed pigment, and printing-ink, pesticide concentrates and drilling mud all provide valuable suspension matrix.In the presence of dense thick solubility ionogen, as Calcium Bromide, they are specially adapted to the closely knit liquid in oil field and (are used to fill the gap between well casing and the boring in the past, mechanical shock takes place to prevent the former), and in the oil well finish liquid (completion fluid) or as cutting liquid or lubricant.
Cenotype
The combined thing of G-of the present invention is mobile strong, but also is used as the suspended solids system.Preferably make this composition with described stablizer, also can make with other deflocculation agent, as EP0346995, the polymkeric substance described in GB2287813 and the WO9106622.
Stable and the novel L that the present invention is identical
1System also can be made with other deflocculation agents rather than described stablizer.Their it goes without doing suspension matrix, but satisfy limpid liquid washing agent and the needs of shampoo under high level of surfactant and ionogen condition.
We find to use the very water-soluble ionogen of high density especially, when preparation contains the composition of a high proportion of relatively nonionogenic tenside as potassium pyrophosphate, obtain a kind of structure phase of not appearing in the newspapers in the past, it contains isotropy dispersive phase, comprise particle diameter and typically be the 1-50 micron, we believe that it is by a micellar phase, may be a kind of L
2Opposite micellar phase perhaps in some cases, may be anhydrous liquid surfactant and a kind of typical isotropic phase, may be L
1The perhaps external phase of aqueous electrolyte, perhaps a kind of mobile intermediate phase such as we think the anisotropy phase composite of the dilution that may be lamellated G-phase.
We are also noted that and add enough dissolved ionogen continuously in the compositions that contains a high proportion of relatively nonionogenic tenside, cause a kind of formation of typical spherulite composition at the beginning, and the electroconductibility of said composition is through a peak value, so reduce to minimumly, it rises to maximum value for the second time apace subsequently.Taking place near Schwellenwert place one obvious variation, this moment is corresponding is that disperse phase is closely filled from little in the external phase of formerly isotropy or weak anisotropy, and the anisotropy spherocrystal becomes bigger, the isotropy droplet that the gap is bigger.In through first electroconductibility that approaches the electroconductibility Schwellenwert, find best solid suspension system.
Novel texture system of the present invention typically contains the nonionogenic tenside that accounts for tensio-active agent gross weight 15%-100%, usually be at least 30%, as 40-90%, be in particular 50-80%, for example pure ethoxyquin compound, or alkylphenol b-oxide are with anion surfactant such as alkylbenzene sulfonate, alkyl-sulphate, or alkyl ethoxy vitriol.Composition also contains high-content solubility ionogen, as is at least 15%(weight) be in particular greater than 18%, be preferably greater than 20%, as potassium pyrophosphate and/or Tripotassium Citrate.
The novel texture composition generally tends to flocculation, and needs the existence of described stablizer so that topple over.
