Description

The method for manufacturing the isotropism aqueous detergent liquid of external structurant

Technical field

The present invention relates to manufacture external structurant aqueous detergent liquid method, for this method clay powders and The structuring of citrus fruit fibres (citrus fibre), homogenized pre-composition and use the structuring, homogenized premix The aqueous detergent liquid of the external structurant of gained prepared by object.

Background technology

Isotropic liquid detergent composition does not have suspended solid particles, such as indicant (cue) and encapsulant (encapsulate) capability.Although can be suspended by suitably manipulating surfactant and electrolyte level Medium, but such method imposes undesirable constraint to composition.This already leads to use so-called outside " structural agent (structurant) ", it now is possible to by the suspension function (duty) needed for its acquisition without the level to component in composition Impose restricted constraint.

The term " outside " used present document relates to structural agent refers to that can be added to preparation, while keeping detergent liquid The reagent of the required fluid properties of body.This is contrasted with " inside " structural agent, and " inside " structural agent is using for example Electrolyte or salt make detergent liquid structuring and its result in from inside can be with the lamellar phase of suspended solid particles or " solidifying Glue ".Although the use of internal structure agent can be the method for the cost-efficient suspension property for generating particle in detergent, But such preparation often has excessively high viscosity, results in the need for rheology modifier.In contrast, it is often preferable to use can be with " outside " is added to preparation, while keeping the reagent of fluid properties.

In the presence of many structural agents applied for detergent.One example of external structurant is citrus fruit fibres.Packet Composition containing citrus fruit fibres and its be used for the description of the purposes in food and personal care composition in US2004/0086626 and In US2009/269376.

In addition, the citrus fruit fibres structural liquid detergent composition of activation exists with the compatibility description for cleaning and nursing enzyme In WO2012/052306.Citrus fruit fibres are combined with Cationic Deposition Polvmer (Jaguar quaternized guars) is used for antidandruff The purposes of shampoo is also disclosed in WO2012/019934.US 7981855 is disclosed comprising up to 15wt% surfactants (comprising at least 1wt% anion surfactants), up to 2wt% bacteria celluloses (preferably MFC) and 0.001 are to 5wt% mandarin oranges The detergent liquid surface activator composition of tangerine fiber.

Unfortunately, when using structural agent of the citrus fruit fibres as detergent preparation of activation, especially when with enough There are disadvantages when high yield strength level use is with suspended solid particles, because ought liquid composition for example be poured out from container When, this can lead to reservation of the residue on container.In addition, when citrus fruit fibres are used alone as external structurant, and do not have When having citrus pulp (citrus pulp) fiber of overprocessing, level of stability needed for composition can not possibly be often obtained.

Such as EP1402877 (Rohm and Haas) and Research Disclosure, in June, 2000, the 434th phase, Disclosed in 1032-1033 pages, another known architectures for suspended solid particles are clay and rheology modification of polymers Combination.

Clay had previously been used as clay colloidal sol in detergent preparation in liquid form.Clay colloidal sol and clay powder Difference lies in by clay is pre-dispersed and the stable components for belonging to supplier of logical usual additional at end.Although molten using clay Glue than being easily processed colloidal sol using clay powders, is thus reduced by the intrinsic of the clay powders sucking generation during handling really Some unique advantages are provided in terms of safety issue, but are led to the problem of using clay colloidal sol other, need to carry out it It solves to allow efficient processing.This problem includes needing to use preservative, because clay is liquid form, Yi Jiyou The increased processing cost caused by the high price of clay colloidal sol and collosol intermixture is processed into volume caused by detergent liquid Outer expense.

In addition, the shortcomings that main thickener in using clay as detergent composition is that they are easy to and other ingredients Interaction, the result is that the viscosity of composition changes over time and syneresis may occur.

Although there is also the preparations used with the citrus fruit fibres of clay aerosol composition as external structurant, also It is found that such preparation shows stability problem.

In reducing preparation cost and overcoming the problems, such as the trial related to known detergent preparation, the present inventor is present Thus gram it has been devised by improved novel method, allows coprocessing structural agent, especially clay powders and citrus fruit fibres, Take intrinsic manufacturing issue and increased cost.

In addition, the present inventor has been designed that novel method now, through this can successfully coprocessing clay powders with For citrus pulp fiber to obtain effective structurant system, which overcome previously undergone when structural agent is used alone or in combination Prior art problem.

Therefore, it is an object of the present invention to provide for manufacturing the isotropism aqueous detergent for being used for external structurant The improved method of the co-structured agent pre-composition of liquid, which overcome the problems related to existing method.

It is a further object to provide the detergent pre-composition preparations and packet of the structural agent comprising coprocessing Isotropism aqueous detergent liquid containing its external structurant.

Specific implementation mode

Detergent composition

1. the citrus fruit fibres of activation

Can be by citrus fruit (mainly lemon and bitter orange) de- juice to leave insoluble plant cell wall material, some Contain sugar and pectin in inside." the sponge micro-structure " for being referred to as white cortex (albedo) can be used for preparing acid powders shape mandarin orange Tangerine fiber.The structure is dry, screening, is washed out to improve fiber content.Dried material is typically big (to have 100 microns of cell fragment is made of the fibrinogen of close adhesion/combination).Powdered citrus fruit fibres material is obtained after grinding Material.The step keeps many natural fine cell walls complete and removes desaccharification.The swellable citrus fruit fibres material of gained is typically used as food additive Add agent and is frequently used for such as low-fat mayonnaise.

Microexamination shows that powdered citrus fruit fibres are the heterogeneous mixtures of the particle with various sizes and shape. The major part of material is made of the aggregation agglomerate of cell wall and cell wall fragments.However, it is possible to identify that many opening diameters are About 10 microns of tubular structure, usual cluster arrangement.These so-called xylem vessels are predominantly located at citrus fruit Water transport channel in skin.Xylem vessel is made of dead cell stacking, they are joined together to form 200 to 300 microns long Relatively long pipe.The lignin enhancing that the outside of pipe is generally ring or spiral is laid with, to prevent pipe due in water delivery process In act on the capillary force of tube wall and cave in.

For preferred type detergent composition and used according to the invention powdered citrus fruit fibres from Herbafoods is with trade (brand) name Herbacel^TMAQ+ type N citrus fruit fibres can obtain.The citrus fruit fibres have total more than 80wt% (soluble and insoluble) fiber content and the soluble fibre content more than 20wt%.It is as the thin drying with light colour Powder supplies and the water binding ability with about 20 kilograms of water of every Kg of powder.

In order to obtain structure appropriate, when forming the pre-composition of the present invention, via high shear dispersion method in water with viscous The powdered citrus fruit fibres of native powder activation (be hydrated and opened in structure).Include in pre-composition by preservative advantageously, This is because the citrus fruit fibres of the activation of dispersion are biodegradable.

Desirably being applied to the shearing of citrus fruit fibres should not up to cause fibril to detach (defibrillation).Cause This, if using high-pressure homogenizer, preferably in 5 000 to 100 000kPa, more preferably between 7 000 to 70 000kPa Operation.The shearing of application is bigger, and gained particle is got over not fine and close.Although changing form by high shear, appear not to change The aggregate size of change method.But fiber is broken, is subsequently filled water phase.Cutting method also rubs the outside of loose fresh fruit cell wall, And these can form the matrix of the water-bound outside the volume by pristine fibre.

Pulpous state citrus fruit fibres produce bacteria cellulose considerably cheaper.

2. water-swellable clay

Suitable water-swellable clay for laundry applications is aqueous layer aluminium silicate (aluminium Phylosilicate), there is iron, magnesium, alkali metal, alkaline-earth metal and the other cations of variable sometimes.Clay forms class It is similar to the flat hexagon piece of mica.Clay is ultrafine particulate (it has been generally acknowledged that being sorted in smaller in dimension than 2 based on standard particle size Micron).

Clay is commonly known as 1:1 or 2:1 clay.Clay is substantially constructed by tetrahedron and/or octahedral sheet.1:1 clay It is made of a tetrahedral sheet and an octahedral sheet, and example includes kaolinite and serpentine.2:1 clay is by being clipped in two Octahedral sheet composition between tetrahedral sheet, and example is illite, smectite (smectite) and attapulgite.

Smectite class includes dioctahedron smectite, such as montmorillonite and nontronite and trioctahedron smectite, such as soap Stone.And bentonite, pyrophyllite, hectorite, sauconite, talcum, beidellite.Other 2:1 clay type includes sepiolite Or attapulgite, it is the clay that there is long aquaporin in its inside configuration.Phyllosilicate includes：Galapectite, kaolinite, she Sharp stone, montmorillonite, vermiculite, talcum, palygorskite, pyrophyllite.Montmorillonite is smectite phyllosilicate (Na, Ca)_0.33(Al,Mg)₂ (Si₄O₁₀)(OH)2·nH₂O.Montmorillonite is very soft laminar silicic acid salt mineral, and it typically is microcosmic crystal forms with shape At clay.Montmorillonite is 2:1 clay, this indicates that it has 2 tetrahedral sheets for accompanying center octahedral sheet.The particle is sheet , with about 1 micron of average diameter.Montmorillonite is the main component of bentonite (volcanic ash sedentary product).Hectorite It is the natural smectite clay with high silicon dioxide content.Natural hectorite is very soft, oiliness white clay mineral.

Suitable water-swellable clay includes：Smectite, kaolin, illite, chlorite and attapulgite.It is such viscous The specific example of soil includes bentonite, pyrophyllite, hectorite, saponite, sauconite, nontronite, talcum and beidellite conduct Smectite type clay.Water-swellable clay is preferably smectite type clay.

Montmorillonitic clay is in the presence of a stabilizer to ionic strength sensitive.They are being typically found in many washings Its liquid structure efficiency is lost under polyelectrolyte level in agent composition.Clay tends to be caved under these conditions certainly With it or flocculate.If this occurs during storage to cave in, liquid will lose its physical stability, experience syneresis and/ Or solid sedimentation.

Preferred water-swellable clay used according to the invention is smectite type clay, selected from Laponite, silicic acid Aluminium, bentonite and pyrogenic silica.Most preferably hectorite is commercially synthesized from BYK Additives (Altana Corporate entity) Laponites.Particularly preferred synthetic li-montmorillonite is：Laponite S、Laponite ES、Laponite RD, Laponite RDS, Laponite XLS, Laponite ESL and Laponite EL.Laponite RD、XLG、D、EL、 OG and LV is entirely lithium metasilicate magnesium sodium.Most preferably Laponite EL, Laponite ESL and Laponite ES.

Other synthetic li-montmorillonite type clays include：Velum Pro and Velum F from RT Vanderbilt, and come From the Barasymacaloids and Proaloids of Baroid division of National Lead Company.

Smectite is synthesized by metal salt, such as the salt and silicate of sodium, magnesium and lithium, especially the combination of sodium metasilicate is controlled Ratio is synthesized at a temperature of.This generates amorphous sediment object, then partially crystallizable.Then the product of gained is filtered, washed, To generate the powder for including tablet (platelet), the tablet has the mean tabular less than 100nm for dry and grinding Object size.Platelet size refers to the longest linear dimension of given tablet.Synthesis of clay avoids using to be existed in natural clay Impurity.

By the ratio that carefully controls and at a temperature of combination sodium, magnesium and lithium salt synthesize Laponite with sodium metasilicate.This Amorphous sediment object is generated, then passes through high-temperature process partially crystallizable.The product of gained is filtered, washed, dried and ground To thin white powder.

The size of clay is important.Therefore, because the small grain size of synthetic li-montmorillonite, very thin synthetic li-montmorillonite It is particularly preferred.Granularity is the discrete particle size for the clay got wet.Suitable granularity is 0.001 to 1 micron, more preferably 0.005 to 0.5 micron and most preferably 0.01 to 0.1 micron.It can be by clay abrasive or crushing so that average-size is in required model In enclosing.

Laponite has the average platelet size full-size less than 100nm.Laponite has layer structure, point It is the plate-shaped crystal form of respectively about 1nm thickness and about 25nm diameters when dissipating in water.Small platelet size provides good Spraying property, rheological characteristic and transparency (clarity).Preferably, clay has the particle size range within the scope of colloid.In general, working as When it is hydrated, such clay provides clear solution, this may be because when clay hydration and stripping (exfoliate), clay Particle does not scatter light.Other larger clays will provide the low-shear viscosity built on demand, but composition will lack transparency.

It is by BYK Additives for the method for the present invention and the most preferred water-swellable clay of detergent preparation With title Laponite EL, ES or ESL supply synthesis of clay because these clays combine very small granularity with to washing Wash the tolerance of high ionic strength present in agent liquid.Laponite EL, ES or ESL form dispersion and have in water High surface charge.In other words give its improved tolerance to electrolyte (including anion surfactant). Laponite EL, ES or ESL can be obtained in the form of two kinds of powder and colloidal sol.Each is suitable in detergent liquid composition.

Laponite has layer structure, is plate-shaped crystal form when being dispersed in water.It can be envisioned for two-dimentional " nothing Machine polymer ", wherein empirical formula form the structure cell in crystal, and the structure cell has two layers for being clipped in four tetrahedron silicon atoms Between six octahedra magnesium ions.These groups are by 20 oxygen atoms and four hydroxyl counters.The height of structure cell represents The thickness of Laponite crystal.Structure cell is repeated many times in both direction, brings the plate-like appearance of crystal.It has been expected typical case Laponite crystal include up to 2000 these structure cells.The macromolecular of the granularity is referred to as colloid.Natural clay mineral increases Thick dose, such as bentonite and hectorite are with similar plate-shaped crystal structure but dimensionally greatly higher than an order of magnitude. The primary particle size of Laponite is more much smaller than natural hectorite or bentonite.Utopian structure will have neutral charge, six A divalent magnesium ion generates 12 positive charges in octahedral layer.However in fact, some magnesium ions are by lithium ion (monovalence) Substitution, and some positions are empty.The clay has 0.7 negative electrical charge per structure cell, is neutralized during manufacture, because of sodium Ion is attracted on plane of crystal.Crystal arrangement is at stacking, by sharing the sodium in the interlayer region between adjacent crystal Ion and electrostatical binding are together.At 25 DEG C in tap water and under fast stirring, this method is substantially after 10 minutes It completes.High shear mixing, raised temperature or chemical dispersant are not needed.The dilution dispersions of Laponite in deionized water The dispersions with low viscosity of non-interaction crystal can be kept for a long time.Plane of crystal has 50 to 55mmol.100^g-1Negative electricity Lotus.Crystal edge has small local positive charge, is generated by the Ions Absorption of crystal structure termination.The positive charge is usual It is 4 to 5mmol.100^g-1.Polar compound (such as simple salt, the surface of solution form are added to the dispersion of Laponite The additive of the forms such as activating agent, agglomerated solvent, soluble impurity and pigment, filler or adhesive) osmotic pressure will be reduced, it keeps Sodium ion is far from particle surface.This makes electric double layer shrink and makes the negativity table of positive charge weaker in crystal edge and adjacent crystal Face interacts.

This method can continue with generation " playing cards room (house of cards) " structure, in Laponite, water and salt Simple system in be considered as high thixotropic gel.The gel is by passing through the combined single coagulated particles group of weak electrostatic force At.

The water-swellable Laponite clays for being used to form the pre-composition in the method for the present invention are powder types and can To be used with the amount of at least 0.04wt%.

Preferably, water-swellable Laponite clays can be used with the amount of at least 0.05wt%.It is highly preferred that water soluble Swollen Laponite clays can be used with the amount of at least 0.06wt%.

In addition, water-swellable clay preferably exists with the amount no more than 3.5wt%.It is highly preferred that water-swellable clay with Amount no more than 3wt% exists.Most preferably, water-swellable clay exists with the amount no more than 2.5wt%.

Laponite EL, ES and ESL clays be also with such as the present invention in preparation containing citrus pulp be used together it is preferred Structural agent because clay makes it possible to obtain the preparation of relatively low citrus pulp as co-structured agent by using clay.

According to the present invention it is possible to by using high-shear mixer, such as Silverson grindings prepare the citrus fibre of activation Peacekeeping caly structure pre-composition.In the method for the invention, can make pre-composition by several successive high shear stages with Ensure the abundant hydration of citrus fruit fibres and clay and disperses to form citrus fruit fibres/clay powders dispersion of activation.

Although pre-composition can be made further to be hydrated (or aging) after high shear dispersion, but it is preferred that in the pre- of activation Mixed object uses when fresh.

In addition, the pre-composition through high pressure homogenization is more preferred than ground pre-composition, because the former for liquid to providing enough Suspension function more weight it is effective.

It has been found that improving homogenization pressures provides the weight efficiency further increased for pre-composition.Suitable operating pressure It is about 5000 to 80000kPa.It is highly preferred that the operating pressure for being about 10000 to 50000kPa can be used.

Because lacking the stability of the detergent preparation prepared under big plant layout sometimes (due in preparation Entrapped air, macro (micronization) of this air usually during grinding by, deteriorate), mechanical degasser also may be used For removing the air for suspending and capturing by process of lapping from the liquid of structuring.

It is used using (co-streamed) water-swellable Laponite clays according to the present invention flowed altogether and citrus pulp fiber In reducing the aeration quantity in preparing, mechanical deaeration amount is thus reduced, the production cost of faster operating time and reduction is caused.

Level of the citrus fruit fibres of activation in pre-composition prepared in accordance with the present invention is preferably 0.2 to 3wt%.More preferably Ground, the level of the citrus fruit fibres of activation in pre-composition prepared in accordance with the present invention is preferably 0.1 to 2wt%.Most preferably, living Level of the citrus fruit fibres of change in pre-composition prepared in accordance with the present invention is preferably 0.04 to 1.5wt%.

However, to there is the reader of technology to will be apparent that concentration of the citrus fruit fibres of activation in pre-composition depends on equipment Cope with the ability of viscosity higher (especially at higher concentrations).

Preferably, amount of the water in pre-composition is at least 20 times of the amount of citrus fruit fibres.It is highly preferred that water is in pre-composition Amount be at least 25 times of amount of citrus fruit fibres.Even further preferably, amount of the water in pre-composition is up to the amount of citrus fruit fibres 50 times.It is also advantageous in that there are excessive water with the citrus fruit fibres of abundant Hydration Activation.Preferred pre-composition has at least 15Pa Measurement yield stress, surveyed at 25 DEG C using Anton Paar zigzag cups and rotor (cup and bob) geometry Measure yield stress.

When being added to liquid detergent composition, the citrus fruit fibres of activation promote composition yield stress and 21^s-1Under Topple over viscosity (pour viscosity), and composition is referred to as shear thinning liquid.Yield stress and 21^s-1Under Viscosity increases generally according to the horizontal of citrus fruit fibres of activation.

The citrus fruit fibres of activation have the advantages that further below：It is used with laundry and residential care detergent composition Enzyme it is compatible.

It can add the water-swellable of preparation according to the present invention clay/citrus pulp pre-composition as rear dosing ingredient It adds in detergent liquid preparation.Alternatively, can be by starting from water-swellable clay/citrus of preparation according to the present invention Then slag pre-composition is added as needed on other ingredients and forms detergent liquid preparation.Some high shears are needed will premix Object is well dispersed in detergent preparation, but high unlike the requirement prepared to pre-composition to the function.

The citrus fruit fibres of activation also have benefited from no air-treatment, because this improves the stability of gained liquid composition, especially It is that " bottom clear layer " is detached.In other words, air, the air of macro cures experience especially in mill (ripening), undesirable " rise " or floating for leading to the fibre structure agent in preparation, lead to detergent preparation Non-uniform appearance.

It is expected that using the citrus fruit fibres of activation to ensure external structurant network not in its dead weight under sufficiently high level Lower sedimentation.If network settles, the solid particle of any suspension settles together with network.In order to avoid in structured network Air entrapment, the amounts of the citrus fruit fibres of activation is preferably decreased to (such as combine for household cleaning close to suspended solid particles The aromatic of encapsulation in object or dento liva of milling (olive stone)) needed for minimum value.

It also have been discovered that the presence of the clay of a part as external structurant system also contributes to reduce detergent group Close the level of the citrus fruit fibres of the activation needed in object.

The citrus fruit fibres of activation according to the present invention/caly structure pre-composition can be alternatively by using high shear mixed Clutch, such as Silverson grind to prepare.Can make the pre-composition of clay and citrus fruit fibres by several high shear stages with Ensure the abundant hydration of citrus fruit fibres and clay and disperses to form the citrus fruit fibres dispersion of activation.After high shear dispersion, Pre-composition can be made further to be hydrated (also referred to as aging).However, it is preferred that being used when the pre-composition of activation is fresh, especially When pre-composition is liquid form, if not using pre-composition within a few hours, lead to increased microbial activity at any time The problem of.

However, the pre-composition through high pressure homogenization is more preferred than ground pre-composition, because the former more weight is effective and is Liquid provides enough suspension functions.In addition, improving homogenization pressures provides the weight efficiency further increased for pre-composition.Properly Operating pressure be about 50000kPa.

3. water

Detergent composition prepared in accordance with the present invention is aqueous, and water forms most of solvent in composition. Can also include hydrotropic agent with degree more smaller than aqueous solvent, such as propylene glycol and glycerine/glycerine are as cosolvent.Group It closes and needs water in object to protect other components of composition, such as surfactant, polymer, soluble builder, enzyme etc. It holds in solution.The water referred in composition includes both free water and any combination water.The amount of water in the composition is preferably extremely Few 20wt%.It is highly preferred that the amount of water in the composition is at least 30wt%.

4. mixed surfactant system

Citrus fruit fibres and clay using activation mean as external structurant to can be used for detergent composition Mixed surfactant system type or amount exist almost without limitation.However, synthetic surfactant is preferably formed as table The major part of surfactant system.Choosing according to formulator to the required cleaning function and required dosage of detergent composition It selects, following whole can be used：The mixture or full anion blending surface of synthetic anionic and nonionic surfactant are lived Property agent system or anion surfactant, nonionic surfactant and both sexes or the blending of zwitterionic surfactant Object.

In addition, the surfactant for forming mixed surfactant system can be selected from description in ' Surface Active Volume 1, Schwartz＆Perry, Interscience 1949, volume 2, Schwartz, Perry＆Berch of Agents ', Interscience 1958, by the ' McCutcheon's published by Manufacturing Confectioners Company Emulsifiers and Detergents ' or ' Tenside Taschenbuch ', H.Stache, second edition, Carl Hauser Verlag, the surfactant in 1981.

The amount of surfactant in the composition can be 3 to 75wt%.It is highly preferred that surfactant is in the composition Amount can be 4 to 60wt%.Most preferably, the amount of surfactant in the composition can be 6 to 50wt%.There is technology Fiduciary (addressee) will additionally appreciate optimum surfactant concentration and will largely depend on product type and expection Use pattern.

Conclusion

Have been observed that (it includes activation and water-swellable according to the method for the present invention from the above experiment and result The citrus pulp of Laponite clay combinations) yield-stress ratio of pre-composition for preparing is related to preparing and only includes the pre-composition of citrus pulp Method it is low.

In addition, it was further observed that for using the total stream method of citrus pulp and water-swellable Laponite clays according to the present invention The pre-composition of preparation, yield stress is increase with time.This pre-composition with only citrus fruit fibres is on the contrary, observe only citrus fruit fibres The yield stress of pre-composition reduces at any time.

Although being not intended to be bound to any particular theory, inventor believes that the surrender of pre-composition prepared in accordance with the present invention is answered The increase of power be due to during citrus pulp activates in citrus pulp fiber include caly structure agent, altogether flow pre-composition with Time gradually forms gel, thus increases the yield stress of pre-composition.

As by lacking bubble and the shortage " reduction " seen in preparation when balance in detergent, (Fig. 3 a are to figure It 3b) proves, when pre-composition is in final detergent liquid preparation, the increased yield stress for flowing pre-composition altogether also carries For static stabilization.

Therefore, because citrus pulp fibre is wherein activated in the presence of water-swellable Laponite clays according to the present invention to using The increased stability that detergent preparation prepared by the pre-composition of dimension is observed, can use lower level structural agent group It closes, such as citrus pulp/clay is 0.05%/0.1%.Due to the unstability of structural agent combination, lower level structuring Agent combination can not achieve and used for detergent compositions designer before.

Therefore, the present invention provides the improved methods for producing stable co-structured agent pre-composition, wherein together It processing structure agent and is handled under lower amount when than being prepared separately, and it can be used to detergent preparations to provide The product for continuing 12 weeks stabilizations at all temperatures thereby conforms to current industrial standards test.
