Description
Technical field
The present invention relates to the water-based isotropy Liquid laundry composition of the external structurant comprising tensio-active agent and suspended particles.
background
Wish microparticle material be mixed in liquid detergent composition, such as packing perfume compound or visual cues (visual cues).Advantageously, the rheological of this liquid should provide the yielding stress (also referred to as critical stress) making particle keep stable suspersion and dispersion.
Propose in water-washing liquid, use external structurant to provide required rheological and suspension effect.
Hydrogenated castor oil (HCO) becomes external structurant by crystallization conversion in this liquid or a part of liquid.This crystallisation process may apply formula restriction, especially when using high surface agent content.The structurized liquid slight haze of HCO, this is not desirable when visual cues is suspended in this liquid.Because HCO structurising agent is formed, if impose extreme temperature to this liquid by cooling---in supply chain or in human consumer's hand, its performance can be reduced.When being added to by packing fragrance microcapsules in the concentrated surfactant solution comprising HCO, micro-capsule has been found in the process of mixing step and has been agglomerated into block.These agglomerates keep not disperseing in this liquid.This improves the visibility of this micro-capsule.When taking out liquid from container, the uneven input of micro-capsule content when this also causes each washing.
A kind of replacement scheme of HCO is by the fibroplastic structured network of insoluble fibrin.A kind of such external structurant system uses microfibrous cellulose (MFC), and it is as used alone in US2007/0197779 or as being combined with HCO in WO2010/048154.But MFC has other shortcoming.First, due to the incorporation that it is extremely low, if form microbubble and retained to make MFC float by this structured network, it cannot keep in a liquid dispersed.This such as occurs during release air in the Thermal Cycling of the product stored.Because needs make HCO keep correct crystal form to provide structurizing effect, the combination of itself and HCO has the same disadvantages of HCO system.
Citrus fruit fibres is described and they are for the structurized purposes of food and personal care composition in US2004/0086626 and US2009/269376.Material can be suspended in this structured compositions by suggestion.The structurized liquid detergent composition of activation citrus fruit fibres and the consistency cleaning and nurse enzyme is described in PCT/EP2011/067549.It is disclosed and Cationic Deposition Polvmer (Jaguar quaternized guar) is used from dandruff control shampoo in WO2012/019934.In US 7981855, disclose the combination of MFC and citrus fruit fibres, it discloses the washings surfactant composition comprising maximum 15 % by weight tensio-active agents (comprising at least 1% anion surfactant), maximum 2 % by weight bacteria celluloses (preferred MFC) and 0.001 to 5 % by weight citrus fruit fibres.Also can entrapped air unstability is fixed when this is combined in be enough to particle suspension amount is in a liquid used.
We have found that, as long as use insoluble fibre cellulose fiber with sufficiently high amount (being enough to make particle to be suspended in yielding stress in isotropy laundry detergent compositions in mode that is stable and dispersion to provide), especially citrus fruit fibres is activated, this fibrous texture network just also can voids, particularly very thin microbubble.Such bubble may be separate out from solution due to the thermal cycling of product or may be formed in said composition manufacture and the process loading its container.The content reducing insoluble fibre cellulose fiber can cause external structurant network failure to make all air be released because of himself buoyancy.This inefficacy is considered to cannot fill up the whole volume of liquid owing to this external structurant network and sink, and reserves limpid non-structured layer at container top.
The citrus fruit fibres of high water binding ability such as can be used as " Herbacel AQ plus citrus fibre " available from HerbaFoods.
Another system being intended to solid particles suspended is as EP1402877(Rohm and Haas) and Research Disclosure, in June, 2000, No. 434, the combination of clay and rheology modification of polymers disclosed in 1032-1033 page.Clay itself can not form stable structure system in water-based isotropy Liquid laundry composition.Thickening polymer must be used to act synergistically with necessity of clay to provide with relatively high content.In addition, these polymkeric substance be found, to the spatter property in laundry composition, there is disadvantageous effect and and other component often existed in liquid washing agent there is unacceptable interaction.Their costlinesses also bring manufacture complicacy.
An object of the present invention is to provide the external structurant system being applicable to water-based isotropy cleaning liquid composition, it provides particle, such as the stable suspension of packing perfume compound, simultaneously can not by bubble destruction stability.
summary of the invention
According to the present invention, provide a kind of water-based isotropy Liquid laundry composition of external structurant, it comprises:
-at least 10 % by weight water,
The mixed surfactant system comprising anion surfactant of-at least 10 % by weight,
-a kind of external structurant system, comprises 0.025 to 0.15 % by weight insoluble fibre cellulose fiber, and it comprises at least 50 % by weight activation citrus fruit fibres,
-at least 0.01 % by weight suspension non-clay solids,
It is characterized in that described external structurant system comprises at least 0.1 % by weight water swellable clays further.
This liquid composition preferably has the yielding stress of at least 0.08 Pa at 25 DEG C.Yielding stress at 25 DEG C is more preferably at least 0.1 Pa, even at least 0.15 Pa.This liquid composition is 20
s-1at least 0.2 Pa.s is preferably with the viscosity at 25 DEG C.
This insoluble fibre cellulose fiber preferably comprises the activation citrus fruit fibres of at least 90 % by weight, most preferably its 100% be activation citrus fruit fibres.Activation citrus fruit fibres is at other detergent ingredients, and especially enzyme is very sane under existing.Said composition preferably comprises at least 0.05 % by weight activation citrus fruit fibres, and more preferably at least 0.07 % by weight.
These suspension non-clay solids are neither liquid neither gas.But they may comprise and are contained in liquid in solid shell or matrix or gas.This shell or matrix may be rigidity or deformable.This liquid preferably comprises at least 0.1 % by weight, even the suspension non-clay solids of at least 0.2 % by weight.Preferred non-clay particulate solid material is micro-capsule.This micro-capsule can have melamine formaldehyde outer shell.Other suitable sheating material can be selected from (gathering) urea, (gathering) carbamate, starch/polysaccharide, aminoplastics and xyloglucan.As fruit instant and desirable, the mixture of dissimilar micro-capsule can be combined.
This micro-capsule can be fragrant capsule.The median size of this micro-capsule is preferably 1 to 100 micron, and the micro-capsule of at least 90 % by weight has the diameter within the scope of this.Preferably the micro-capsule of 90 % by weight has 2 to 50 microns, the more more preferably diameter of 5 to 50 microns.The most preferably diameter micro-capsule that is less than 30 microns.
The non-clay particulate solid material substituted or add comprises visual cues, the mark preferably formed by the thin-film material comprising polymkeric substance, to provide visual effect to greatest extent by the marking materials of low weight.The visual cues be made up of film can be 2 to 5 mm dias (overall dimension).
This clay preferably has and is less than 250 microns, is more preferably less than the granularity of 100 microns.The D of this clay
50granularity is preferably less than 50 microns.This clay can be used as dry starting material or gel or the form be more easily distributed in CFF and water pre-composition and uses.
In this external structurant system, the total amount of the insoluble fibre cellulosic material and clay that comprise activation citrus fruit fibres is preferably in the scope of 0.10 to 0.80 % by weight.
Preferably comprise at least 50 % by weight activation citrus fruit fibres, more preferably at least 90 % by weight, the insoluble fibre cellulose fiber most preferably comprising 100% activation citrus fruit fibres can give the suspension character of isotropy cleaning liquid composition excellence.But, also easily by mixing, transport and filling process entrapped air.Degassing equipment is used to be difficult to solve the entrained air in late period in filling process.When utilizing high-shear dissemination to activate the fiber of formation external structurant network, entrained air is a large problem.This may have from comprising 100% the micro-air discharged the external structurant system of the insoluble fibrin fibre network of the yielding stress being high enough to suspending solids material owing to being formed in reactivation process and seeming difficult especially.This air can accumulate to the amount being enough to this structured network " is floated ".
Such as, when using needed for suspension fragrance microcapsules 0.25 % by weight activation citrus fruit fibres as external structurant system in washing liquid, it also can make the air suspension of carrying secretly, and the air of this suspension makes the fibre network of this external structurant system rise.This produces again the uneven liquid of the micro-capsule that to fall apart containing difference.The reduction of activation citrus fruit fibres amount can be sunk due to this external structurant system and make the scarce capacity from suspending or making micro-capsule suspend in a dispersed form.
Be well known that, clay generally cannot oneself suspend with colloidal dispersion form in high surfactant liquid.But, we have found that, low amounts insoluble fibre cellulose fiber, the combination of preferred activation citrus fruit fibres and other water swellable clays do not suspended provides the structurizing system of stable storing, and it can make micro-capsule keep fully dispersion and unstability can not determine because of the air retained.With use alone compared with (high-content) activation citrus fruit fibres, also improve the painted of liquid.
detailed Description Of The Invention
water
This detergent composition is water-based, and water forms the most of solvent in said composition.Hydrotrote can be comprised, if propylene glycol and glycerine are as solubility promoter with the amount fewer than water.Water is needed to make tensio-active agent, any polymkeric substance, solvable washing assistant, enzyme etc. keep dissolving in the composition.The described water yield comprises free-water and any Bound moisture.The water yield in said composition is preferably at least 20 % by weight, more preferably at least 30 % by weight.
mixed surfactant system
Due to the sane character of this novel external structurant system, to the type of mixed surfactant system or quantitative limitation little.Synthetic surfactant preferably forms the major portion of this surfactant system.The mixing of the mixture of synthetic anionic and nonionogenic tenside or full anionic mixed surfactant system or anion surfactant, nonionogenic tenside and both sexes or zwitterionics all can for the choice for use measured needed for required clean up task and detergent composition according to formula teacher.
The tensio-active agent forming mixed surfactant system can be selected from " Surface Active Agents ", 1st volume of Schwartz & Perry work, Interscience 1949, Schwartz, the volume Two of Perry & Berch work, Interscience 1958, ' McCutcheon's Emulsifiers and Detergents ' or " Tenside Taschenbuch " that Manufacturing Confectioners Company publishes, H. Stache, 2nd edition, Carl Hauser Verlag, the tensio-active agent described in 1981.
Tensio-active agent amount in the composition can be 3 to 75 % by weight, preferably 10 to 60 % by weight, more preferably 16 to 50 % by weight.Technician will appreciate that, optimum surfactant concentration greatly depends on product type and expection using forestland.
Anion surfactant can comprise soap (salt of lipid acid).Preferred soap by hydrogenated coconut oil fatty acid, such as Prifac 5908(is from Croda) neutralization make.Also saturated and mixture that is unsaturated fatty acids can be used.
Nonionic detergent tensio-active agent is as known in the art.Preferred nonionogenic tenside is the C12-C18 ethoxylated alcohol that per molecule comprises 3 to 9 ethylene oxide units.More preferably there are average 5 to 9 ethylene oxide groups, more preferably the linear primary ethoxylated alcohols of C12-C15 of average 7 ethylene oxide groups.
The example of suitable synthetic anion surface active agent comprises sodium lauryl sulphate, sodium lauryl tri(oxyethyl) sulfate, dodecyl sulfo-succinic acid ammonium, ammonium lauryl sulfate, ammonium dodecyl ether sulfate, cocounut oil acyl hydroxyethyl sulfonate, lauroyl hydroxyethyl sulfonate and N-sarcosyl.Most preferred synthetic anion surface active agent comprises synthetic anion surface active agent linear alkylbenzene sulfonate (LAS).Being applicable to another synthetic anion surface active agent of the present invention is alcohol ethoxy ether sodium sulfate (SAES), preferably comprises the C12 alcohol ethoxy ether sodium sulfate (SLES) of a large amount.Said composition preferably comprises LAS.
Preferred mixed surfactant system comprises synthetic anionic and nonionic detergent active material and optional amphoterics, comprises amine oxide.
Another preferred mixed surfactant system comprises two kinds of different anion surfactants, preferred linear alkylbenzene sulfonate and vitriol, such as LAS and SLES.
Synthetic anion surface active agent can such as exist to about amount of 70 % by weight with about 5 % by weight of this mixed surfactant system.
This detergent composition can comprise amphoterics further, and wherein amphoterics is with 1 to 20 of this mixed surfactant system % by weight, and preferably 2 to 15 % by weight, more preferably the concentration of 3 to 12 % by weight exists.Suitable both sexes and the representative instance of zwitterionics are alkyl betaine, alkyl amido betaine, amine oxide, aminopropan acid esters, aminoglycinate, amphoteric imidazoline compound, alkyl dimethyl betaine or alkyl two polyethoxye trimethyl-glycine.
insoluble fibre cellulose fiber
This external structurant system is made up of water swellable clays and one or more insoluble fibre cellulose fibers (comprise at least 50 % by weight and activate citrus fruit fibres, more preferably comprise 90 % by weight activation citrus fruit fibres, most preferably comprise 100 % by weight activation citrus fruit fibres).Pristine fibre possibility part is solvable, and all amounts therefore provided in this specification sheets comprise insoluble and soluble part.This fiber may be all a type or may use as blend fiber system.Optimum fiber is by bacteriogenic microfibrous cellulose and the natural origin fiber from plant.Due to the water-absorbent that it is very high, use activation citrus fruit fibres.Generally speaking, water-absorbent is higher, this fiber or fibre blend more preferred.Many commentaries about the processing of citrus fruit fibres are also applicable to the insoluble fibre cellulose fiber of other type.
activation citrus fruit fibres
The white cortex (albedo) of citrus fruit is used to manufacture powdery citrus fruit fibres.It has " spongy microstructure ".By de-for citrus fruit (mainly lemon and bitter orange) juice to leave insoluble Plant cell wall material and some sugar included and pectin.Be dried and sieve, then washing to improve fibre content.Dry material is large grain (100's micrometer cell fragment, is made up of the protofibril of combining closely).After grinding, powdery citrus fruit fibres material is obtained.Method therefor makes a large amount of natural fine cell wall remain intact, simultaneously except desaccharification.Gained high swelling property citrus fruit fibres material is often used as foodstuff additive also for low fat mayonnaise.The pH of this dispersed powders is acid.
Microscopy shows, powdery citrus fruit fibres is the Inhomogeneous charge thing of the particle with various size and shape.This material major part is made up of the gathering agglomerate of cell walls and cell wall fragments.But, the tubular structure that many opening diameters are about 10 microns can be identified, usual cluster arrangement.These so-called xylem vessels are the water transport channel of the skin being mainly arranged in citrus fruit.Xylem vessel is formed by dead cell is stacking, and they are joined together to form the relatively long pipe of 200 to 300 microns long.The outside of these pipes is generally the xylogen enhancing of ring or spiral laying, caves in owing to acting on the capillary force of tube wall in water delivery process to prevent these pipes.
The powdery citrus fruit fibres of preferred type is Herbafoods ' Herbacel AQ+ N-type citrus fruit fibres.This citrus fruit fibres has total (the solvable and soluble) fibre content being greater than 80% and the soluble fibre contents being greater than 20%.It is as the thin dry powder supply with low color and have the water binding of about 20 kg water of every Kg of powder.
In order to obtain suitable structure, by high-shear dispersion activation (hydration structurally open) powdery citrus fruit fibres at low concentrations in water to form pre-composition.Because the activation citrus fruit fibres of dispersion is biodegradable, it is favourable for comprising sanitas at this pre-composition.
Shear and should not be high enough to cause defibrillation (defibrillation).If use high-pressure homogenizer, it should run between 200 to 600 bar.The shearing applied is larger, and gained particle is not finer and close.Although high-shear can change form, seem to change technique aggregate size.Fiber is broken, then fills aqueous phase.Shear the outside of also rubbing loose cell walls with the hands, and these can form the matrix of the water structure outside the volume of pristine fibre.
Or, by using high shear mixer, citrus fruit fibres addition of structurant can be activated as Silverson grinding manufactures.This pre-composition can be made through several continuous print high-shear stage to guarantee that the complete hydration of citrus fruit fibres and dispersion are to form activation citrus fruit fibres dispersion.The further hydration of this pre-composition (aging) is made after high-shear dispersion.The preferred fresh use of pre-composition of activation.
The pre-composition of high pressure homogenization is better than ground pre-composition because they more weight be that liquid carrying is for sufficient suspension effect effectively.The raising of homogenization pressures improves the weight efficiency of this pre-composition further.Suitable operating pressure is about 500 barg.
Activation citrus fruit fibres content in pre-composition preferably 1 to 5 % by weight, more preferably 1.5 to 2.5 % by weight scope in.Activation citrus fruit fibres concentration in pre-composition depends on that equipment deals with the ability of the viscosity higher brought by higher concentration.The water yield in pre-composition is preferably at least 20 times of citrus fruit fibres amount, more preferably at least 25 times, even up to 50 times.Excessive water is favourable to make the abundant hydration of activation citrus fruit fibres.
Preferred pre-composition has the yielding stress of at least 70 Pa using Anton Paar zig-zag cup and rotor (cup and bob) geometry to record at 25 DEG C.
When adding in cleaning liquid composition, activation citrus fruit fibres promote said composition yielding stress and 20
s-1under topple over viscosity and said composition is shear-thinning liquid.Yielding stress and 20
s-1under viscosity substantially unanimously with activation citrus fruit fibres content to improve.
Activation citrus fruit fibres is compatible with enzyme used in household care detergent composition with laundry.
This pre-composition can add in washings as the composition of rear input, or by this pre-composition, then can add to wherein by other composition, form said composition thus.Need certain high-shear to be well dispersed in said composition by this pre-composition, but this effect so need unlike for pre-composition preparation.
The insoluble fibre cellulose fiber comprising activation citrus fruit fibres should use with sufficiently high content to guarantee that external structurant network can not sedimentation under its own weight.If this network sedimentation, the solids of any suspension can with this network sedimentation.For avoiding air entrapment in structured network, preferably the amount of activated fiber is down to close to making solids, such as, minimum quantity needed for packing perfume compound suspends.The clay fraction of this external structurant system contributes to the activated fiber amount needed for reduction.
water swellable clays
Suitable water swellable clays is hydrated aluminum phyllosilicate, sometimes has the iron of variable quantity, magnesium, basic metal, alkaline-earth metal and other positively charged ion.Clay is formed and hexagon sheet like mica group.Clay is ultrafine particulate (being usually considered to be less than 2 micron-scales in standard particle size classification).
Clay is often referred to as 1:1 or 2:1.Clay is made up of tetrahedral sheet and octahedral sheet substantially.1:1 clay is made up of 1 tetrahedral sheet and 1 octahedral sheet, and example comprises kaolinite and serpentine.2:1 clay is made up of the octahedral sheet be clipped between two tetrahedral sheets, and example is illite, montmorillonite and attapulgite.
Montmorillonite (smectite) class comprises Dioctahedral smectite, as polynite (montmorillonite) and nontronite, and trioctaedric smectite, such as saponite.And wilkinite, pyrophyllite, hectorite, sauconite, talcum, beidellite.Other 2:1 clay type comprises sepiolite or attapulgite---there is the clay of long aquaporin in their structure.Phyllosilicate comprises: halloysite, kaolinite, illite, polynite, vermiculite, talcum, polygorskite, pyrophyllite.Polynite (montmorillonite) is montmorillonite phyllosilicate (smectite phylosilicate) (Na, Ca)
0.33(Al, Mg)
2(Si
4o
10) (OH) 2nH
2o.Polynite is very soft phyllosilicate class mineral, and it is usually with micro-crystal formation to form clay.Polynite is 2:1 clay, means that it has two tetrahedral sheets clamping middle octahedral sheet.This particle is sheet shape, and mean diameter is about 1 micron.Polynite is the main component of wilkinite-a kind of volcanic ash sedentary product.Hectorite is the natural smectite clay with high silicon dioxide content.Natural water pyroxene is rare soft, greasy, white clay mineral.
Suitable water swellable clays comprises: montmorillonite, kaolin, illite, chlorite and attapulgite.The specific examples of this type of clay comprises wilkinite, pyrophyllite, hectorite, saponite, sauconite, nontronite, talcum and beidellite as clay of smectite type.This water swellable clays is preferably clay of smectite type.
Polynite is even in the presence of a stabilizer also to ionic strength sensitive.Their liquid structure efficiency is lost under the high electrolyte content that they usually exist in many detergent composition.Clay tends under these conditions from caving in or flocculating.If there is this caving in storage process, this liquid can lose its physical stability, disturbed in synersis and/or solid settlement.
Preferred water swellable clays is the clay of smectite type being selected from Laponites, pure aluminium silicate, wilkinite and aerosil.Most preferred business synthetic hectorite is the Laponites from Rockwood.Particularly preferred synthetic hectorite is: Laponite S, Laponite RD, Laponite RDS, Laponite XLS and Laponite EL.Most preferably Laponite EL.Laponite RD, XLG, D, EL, OG and LV are lithium silicate magnesium sodium.
Other synthetic hectorite type clay comprises: from the Veegum Pro of RT Vanderbilt and Barasymacaloids and Proaloids of Veegum F and the branch Baroid from National Lead Company.
Synthesis montmorillonite by metal-salt, as salt and the silicate of sodium, magnesium and lithium, especially water glass be combined in controlled rate and temperature under synthesize.This produces amorphous throw out, its subsequent portion crystallization.Then filtered by products therefrom, washing, dry also grinding is to produce containing lamellated powder, and it has the average flake size being less than 100 nanometers.Lamina dimensions refers to the longest linear dimension of given thin slice.Synthesis of clay is avoided being used in the impurity found in natural clay.
By merging salt and the water glass of sodium magnesium and lithium under the ratio carefully controlled and temperature, synthesis Laponite.This produces amorphous throw out, and it is subsequently by pyroprocessing partial crystallization.Filtered by products therefrom, washing, drying also grinds to form white fine powder.
The granularity of this clay is important.Therefore, superfine synthetic hectorite is especially preferred due to their small grain size.Granularity is the size of the discrete particle of moistening clay.Suitable granularity is 0.001 to 1 micron, more preferably 0.005 to 0.5 micron, most preferably 0.01 to 0.1 micron.By this clay abrasive or can pulverize to make mean particle size within the required range.
Laponite has the average sheet overall dimension being less than 100 nanometers.Laponite has Rotating fields, is the dish type crystalline form of about 1 nanometer thickness and about 25 nanometer diameters separately when it is dispersed in water.Small thin slices size provides good spraying property, rheological and clarity.This clay preferably has the size range within the scope of colloid.This type of clay provides clear solution usually when hydration, may be because when this clay water merges stripping, clay particles is scattered light not.Other larger clay can provide the low-shear viscosity formed on demand, but said composition lacks clarity.
This clay with at least 0.05 % by weight, preferably at least 0.1 % by weight, more preferably the amount of at least 0.2 % by weight is present in said composition.
This clay is preferably to be not more than 0.7 % by weight, and more preferably no more than 0.6 % by weight, the amount being most preferably not more than 0.5 % by weight exists.
The use of colloidal sol level synthesis of clay reduces the intermittent time (batch time), and this is favourable.
Rockwood using Laponite EL run after fame supply synthesis of clay most preferably as water swellable clays.It has minimum granularity and the tolerance to the high ionic strength existed in washings concurrently.Laponite EL forms dispersion and has high surface charge in water.This allegedly gives its tolerance to ionogen (comprising anion surfactant) improved.Laponite EL can obtain with powder and solation.Any one is all applicable to cleaning liquid composition.
It is the Rotating fields of dish type crystalline form that Laponite has when being dispersed in water.It can be envisioned for two dimension " inorganic polymer ", and wherein this empirical formula forms the structure cell in crystal, and it has six the octahedra magnesium ions be clipped between two layers be made up of four tetrahedron Siliciumatoms.By 20 Sauerstoffatoms and 4 these groups of hydroxyl counter.The height of this structure cell represents the thickness of Laponite crystal.This structure cell repeats many times in both direction, to bring the plate-shaped appearances of this crystal.Estimate, typical Laponite crystal contains maximum 2000 these structure cells.The macromole of this granularity is referred to as colloid.Natural clay mineral thickening material, as wilkinite and hectorite have similar dish type crystalline structure, but large more than one magnitude dimensionally.The primary particle size of Laponite than natural water pyroxene or wilkinite much smaller.Utopian structure has neutral charge, has 6 divalence magnesium ions in octahedral layer, to produce 12 positive charges.But in practice, some magnesium ions are replaced by lithium ion (monovalence) and some positions are vacated.The every structure cell of this clay has 0.7 negative charge, and it is neutralized in the fabrication process, because sodium ion is adsorbed to plane of crystal.Crystal stacked arrangement, by sharing sodium ion in the interlayer region between adjacent crystal, by their electrostatical bindings together.Under 25oC, in tap water and under fast stirring, this process completes after 10 minutes substantially.Do not need high shear mixing, the temperature of rising or chemical dispersant.Laponite rare dispersion in deionized water can remain the dispersions with low viscosity of non-interaction crystal for a long time.Plane of crystal has 50 to 55 mmol.100
g-1negative charge.Crystal edge has the little local positive charge generated by ionic absorption, and crystalline structure terminates at this.This positive charge is generally 4 to 5 mmol.100
g-1.Polar compound (simple salt, tensio-active agent, agglomerated solvent, soluble impurity and additives in such as pigment, filler or tackiness agent etc.) is in the solution added in Laponite dispersion and can reduce osmotic pressure to make sodium ion away from particle surface.This makes this electrical double layer shrink and allows the negativity surface interaction of more weak positive charge in crystal edge and adjacent crystal.
The method can continue to produce " playing cards room (house of cards) " structure, and it is counted as high thixotropic gel in the simple system of Laponite, water and salt.This gel is made up of the single flocculate particles combined by weak electrostatic force.
suspension non-clay particle
Said composition comprises suspension non-clay particle.These particles are preferably solid; Namely they are neither liquid neither gas.But in term solid, we comprise the particle with rigidity or deformable solid shell, it subsequently can containing fluid.Such as these solids can be micro-capsules, as fragrant capsule, or the nursing agent additive of encapsulated forms.This particle can be insoluble composition, as the form of silicone, quaternary material, insoluble polymer, insoluble brightening agent and other the known beneficial agent as described in such as EP1328616.The amount of suspended particles can be 0.001 to being up to 10 or even 20 % by weight.The solids of the type suspended are visual cues, the flat film mark of the type such as, described in EP13119706.This mark itself may contain separation (segregated) component of this detergent composition.Because this mark must water soluble but be insoluble to said composition, it is made up of modified polyvinyl alcohol insoluble in the presence of mixed surfactant system easily.In this case, this detergent composition preferably comprises at least 5 % by weight anion surfactants.
Suspension non-clay particle can be any type.This comprises the solid opacifying agent of fragrant capsule, nursing agent capsule and/or visual cues or suspension, as the mixture of mica or other pearlescent material suspended and these materials.The density of suspended particles is more mated with the density of this liquid and the liquid added before this external structurant is thicker, and suspensible particle weight is larger.Usually, the maximum suspended particles of 5 % by weight of this mixing external structurant stable system suspension can be used; But the amount being up to 20 % by weight is possible.
Realize by providing yielding stress suspending.Yielding stress needs to be greater than by this micro-capsule or mark applying stress on that network, otherwise can destroy this network, and particle can sink or float, and depends on that whether they are closeer than matrix liquid.Fragrance microcapsules almost has neutral buoyancy (neutrally buoyant) and little, and therefore required yielding stress is low.Bubble is comparatively large and have maximum density difference, therefore needs high yielding stress (>0.5 Pa, depends on bubble size).If yielding stress is not too high, bubble can by floating and being separated with surface and overflowing.
Micro-capsule preferably comprises solid shell.Should fully disperse micro-capsule with anionic charge to avoid agglomeration problem.Also the micro-capsule with cationic charge can be used.This micro-capsule can have melamine formaldehyde outer shell.Other suitable sheating material can be selected from (gathering) urea, (gathering) carbamate, starch/polysaccharide, xyloglucan and aminoplastics.

This micro-capsule can be attached in suitable substrate, such as, to provide the permanent fragrant of desirably release after cleaning course completes.
liquid detergent composition
This detergent composition has at least 0.08 Pa, preferably at least 0.09 Pa, more preferably at least 0.1 Pa, even the sufficient yielding stress recorded at 25 DEG C of at least 0.15 Pa, also referred to as critical stress.The yielding stress level that these increase progressively can suspend the particle increased progressively with the density difference of bulk liquid (bulk liquid).The yielding stress of 0.09 Pa is found to be enough to suspend the fragrant capsule of most of type.Pure clay is unstable and cannot provide the resulting structure of water-based isotropy cleaning liquid composition.Mixing external structurant system also keeps dispersion; Neither float (isolating lower clear layer), also do not sink (isolating supernatant layer).By guaranteeing that this structurizing system will occupy the whole volume of washings, realize this from suspending.This depends on the amount of clay used and cellulosic fibre.Only realizing this point by activation citrus fruit fibres makes the so high consequently bubble of yielding stress suspend, and these make this structured network unstability fixed subsequently.
This washings can be formulated as be applied directly in substrate or for after dilution (as before this liquid composition of use or dilute by human consumer or in washing device in process) be applied to suprabasil concentrated cleaning solution.

measuring method
In suspension compared with under the insoluble fibre cellulose fiber of the higher amount needed for heavy particle, become too large from forming separately the water yield removed the matrix of pre-composition, therefore the rear input of addition of structurant is not feasible selection.On the contrary, structurizing detergent composition can be prepared by activated fiber, in activated fiber, add other composition with they normal interpolation order.Except can the activated fiber of more high-content be mixed except washings, this has another advantage, namely in the adding procedure of following component (comprising the clay of rear interpolation), continue through high-shear dispersion activated fiber but not as rear shearing step, reduce the intermittent time thus.We have found that, best practice is before liquid composition is loaded container, it is degassed.But this external structurant system allows larger technological flexibility and this step is not basic.
