Description
Technical field
The present invention relates to detergent composition, especially structured liquid detergent compositions.
Background and prior art
Liquid detergent composition has some advantage than granular detergent composition.For example, liquid composition is prepared burden easily and is made the human consumer not worry that fabric is impaired.This may be exactly why to introduce market since heavy duty type and the composite laundry detergent product of light-duty just to obtain the reason greatly popularized.
Have two classes common and independently liquid detergent composition, i.e. isotropy and structural liquid.Isotropic liquid is that wherein all components all is dissolved, and opposite with structural liquid, does not have structure to exist in isotropic liquid.
In structural liquid, can make structural contribution go out some character such as flowing property that the human consumer liked and/or muddy outward appearance.Many structural liquid granular solids that also can suspend.The example of structural liquid is at US-A-4244840, and EP-A-0160342 provides among EP-A-0038101 and the EP-A-0140452.Structural liquid can be " inner structure ", its structure is formed by initial component, preferably use surfactant material, and/or " outer structure ", its structure is to form by using three dimensional matrix (matrix) structure that auxiliary additive provided, additive preferred polymers, clay, silica and/or silicate material.Outer structure liquid can provide the high viscosity when storing.
Usually, the ordering degree that contains surfactant system increases with the increase of tensio-active agent and/or electrolyte concentration.When tensio-active agent and/or electrolytical concentration were extremely low, tensio-active agent can be used as molecular solution and exists, or existed as the solution of spherical micelle, and these two kinds of solution all are isotropic, and promptly they are amorphousness.Because tensio-active agent and/or electrolytical adding in addition, the structure of surfactant material can form.This structure has multi-form existence, as bilayer structure.They are called as with different terms, as rod-shaped micelle, and anisotropic surface promoting agent phase, plane laminate structure, stratiform droplet and mesomorphic phase.The various examples of the liquid with inner structure that formed by tensio-active agent are at H.A.Barnes, " Detergents (washing composition) ", chapter 2, K.walters (volume) " Rheometry:Industrial Applications (rheometry: industrial application) ", J.Wiley ﹠amp; Sons provides among the Letchworth 1980.Usually, different workers are actually identical structure with different term addresses.For example, in european patent application specification sheets EP-A-0151884, the stratiform droplet is called as spherocrystal.
The feature of preferred laminate structure is the stratiform droplet of surfactant material at continuous aqueous phase, and wherein the dispersive structure generally is considered to be made up of the class onion configuration that contains the concentric bilayer surfactant molecule mutually, is sealing water up for safekeeping between bilayer, i.e. water.Liquid with stratiform droplet structure is preferred, because this droplet tightly packed provides the ideal structure of physical stability and useful flowing property in the system, promptly good pourability combines with enough stability.This class I liquid I is at for example A.Jurgews, Micro-Structure andViscosity of Liquid Detergent (microstructure of liquid washing agent and viscosity), Tenside Surfactant Detergents 26 (1989), 222 pages and J.C.Van dePas, Liquid Detergents, Tenside Surfactants Detergents28 (1991) states in 158 pages.The existence of surfactant structure system and characteristic can be measured with the known method of person skilled in the art in the liquid, optical technology for example, various rheological measurements, X ray or neutron diffraction and electron microscopy sometimes.
The feasible composition that is difficult to prepare chemistry and physically stable of a large amount of interactions in the liquid detergent composition between the component is particularly when storing.It is inhomogeneous that this detergent composition can become, and for example some components can be separated owing to crystallization or precipitation.Liquid washing agent be their solubility property on the other hand.So far, few people are put into attention on the solubility property of liquid washing agent.When using detergent composition, the user likes seeing its dissolving rapidly in water.It is active fully that this makes the user be sure of that detergent composition becomes very soon.Structured liquid detergent compositions dissolves rapidlyer than powder detergent.But for can be used for the hand washing operation, comprise the liquid detergent composition of laundry, need extremely excellent solubility property.Low viscosity liquid washing composition such as pure nonionogenic tenside demonstrate trouble and bad solubility property, and this is because the formation of intermediate phase.Another solvability can problematic example be under the situation of the laminate structure liquid washing agent of also being made up of intermediate phase also.Although we do not wish to be bound by any theory, we believe that the dissolving that contains the structured liquid detergent of stratiform droplet can be divided into two-phase.In first phase of dilution, droplet disperses, and in second phase decomposition.Yet dilute with water can cause the reduction of the outer salt concn of stratiform droplet.Because osmotic pressure is, this can cause the swelling of stratiform droplet.Such process can help to explain the bad solvency action of some structured liquid detergent.
Many structured liquid detergent compositions can suspended solids, as zeolite.Yet with regard to rheology and stability, such composition causes some problems deserving of attention, because solid should keep in week suspending at 1-3 at least, the while composition should keep pourability.Yet solid suspends and is not always required.So do not contain stable suspersion solid structured liquid detergent is preferred, because these compositions needn't satisfy such strict demand and thereby can be easier to preparation.Yet technology the earliest relates to have the structural liquid of stable suspersion solid.
EP-A-301882 discloses has the structured liquid detergent compositions of stable suspersion solid as 20% weight zeolite.The solubility property of these compositions is not open.EP-A-362916 relates to and mixes the high-content functional polymer, to suppress the effect of fabric softening clay.The composition that is exemplified can suspended solids.The solubility property of the composition that obtains is unclear.EP-A-829530 has described and has contained the structural hard surface detergent compositions of stable suspersion solid.Solubility property about the composition that exemplifies is not open.EP-A-74134 discloses has stable suspersion solid structured liquid detergent compositions.This patent is described, if use sodium xylene sulfonate or toluenesulfonic acid sodium salt to obtain suitable viscosity and satisfactory stability, then S-WAT can be used for having the composition of high-content Tri sodium Phosphate (25-26%).Solubility property about disclosed composition does not disclose therein yet.
Therefore, be still needs for not containing stable suspersion solid rock steady structure liquid detergent composition, it should have the good solubility energy, as not showing one or more shortcomings of pointing out above.
Astoundingly, we have now found that preparation rock steady structure liquid washing agent is possible, and it shows outstanding dissolution rate, if viscosity is 21S in shearing rate
-1The time be lower than 500mPaS, said composition does not contain deflocculate polymkeric substance and stable suspersion solid substantially.
Explanation of the present invention
The present invention relates to a kind of stable structure liquid detergent composition, it is characterized by:
(i) at 25 ℃ of these polymkeric substance after 21 days generation is lower than being separated of 10% volume from when preparation; With
Be 21 S (ii) in shearing rate
-1The time viscosity be lower than 500mPaS; With
(iii) when the 10ml said composition being dissolved in 2.51 25 ℃ and 4 H water, dissolution time as measuring, is less than 120 seconds here; With
If (iv) said composition contains the polymkeric substance of visbreaking, then the visbreaking polymkeric substance is not single by dextran, and dextran sulfonate or polyoxyethylene glycol are formed; As long as when composition contains 10.4% weight Sodium dodecylbenzene sulfonate, 6.7% weight C
12-13Every mole on average by the oxyalkylated Fatty Alcohol(C12-C14 and C12-C18) of 7mol oxyethane, 4.6% weight sodium-chlor, so said composition contain at least a single be that the sodium polyacrylate of 1200-8000 is formed by weight-average molecular weight; Said composition is substantially free of deflocculate polymkeric substance and stable suspersion solid.
In this article, contain stable suspersion solid composition and be situation about can be under normal pressure not showing in the composition in 25 ℃ of 20% 3 weeks of weight zeolite 4A that suspended greater than top layer 2%, the contained zeolite in upper strata is less than bottom.
And another specific embodiments provides the method for a usefulness liquid detergent composition cleaning clothes of the present invention.
Detailed description of the present invention
The dissolution rate that the water-bearing structure liquid detergent composition is lower may be the main drawback that the user perceives.High dissolution rate makes the user be sure of that liquid detergent composition is consoluet and thereby is active fully.This point is applicable to all liquid detergent composition usually, but especially for the liquid detergent composition that is fit to the hand washing operation.Favourable dissolution rate is to be less than 120 seconds when dissolution time (as measuring below), preferably is less than 100 seconds, more preferably less than 90 seconds, more preferably less than 80 seconds, when most preferably being less than 60 seconds.According to the present invention, the 10ml liquid washing agent is added in the 3L beaker (diameter 14cm) that fills 2.5L4 H water (at 25 ℃) through a syringe with common flow.(the long 6cm of rod) stirs the water in the beaker with magnetic stirrer, and the mode of stirring should make beaker central authorities form the vortex of 1cm.Liquid washing agent is added in the outside of vortex.The record specific conductivity is as the function of time, from walls of beaker 1cm, until reading constant (all liquid washing composition all dissolves).By the gained data make even the weighing apparatus electric conductivity value reach 90% Time Calculation dissolution time, promptly when 90% weight combinations thing dissolves.
We find, when preparation has the liquid detergent composition of favourable dissolution rate, are wonderful big factors with viscosity limitation to the specific level of liquid detergent composition.
Visbreaking
The viscosity of the present composition can be controlled with known the whole bag of tricks in the present technique.In a preferred embodiment, a composition contains just like the visbreaking polymkeric substance described in the EP-A-0301882.This visbreaking polymkeric substance is compared with the same composition that is removed except all these base polymers and can be reduced the viscosity of composition that (in shearing rate is 21S more than 5%
-1Under when measuring).A large amount of different polymkeric substance can be used, as long as the requirement of electrolytic resistance and vapour pressure is satisfied.The former is that conduct is that the amount that reaches the necessary sodium nitrilo triacetate of cloud point (NaNTA) of the solution of 100ml 5% polymkeric substance in 25 ℃ of water is measured, and the pH of regulation system is neutral simultaneously, promptly is about 7 and preferably reaches this purpose with sodium hydroxide.Most preferred electrolytic resistance is 10g NaNTA, especially 15g.The requirement of vapour pressure shows that vapour pressure will be hanged down is enough to have tangible water binding ability, as what illustrate among the GB-A-2053249.Thereby the vapour pressure of polymkeric substance 20% aqueous solution preferably is equal to or less than the vapour pressure that molecular-weight average is 10% weightaqueous solution of 6000 polyoxyethylene glycol.It is emphasized that with the present invention to differ widely that EP-A-0301882 discloses and how to have removed to improve the pourability (page 2,43 row) of liquid and not point out may influence solubility property with the visbreaking polymkeric substance.In a preferred embodiment, composition of the present invention contains greater than 0.01%, is preferably greater than 0.05%, more preferably greater than 0.1% with less than 10%, preferably less than 5%, is more preferably less than the visbreaking polymkeric substance of 2.5% weight.Content is higher than these numerals and can causes instability in many compositions (but not being whole).
The visbreaking polymkeric substance is optional from polyacrylic ester, polysaccharide, modified polysaccharide, polyalkylene oxide, Polyvinylpyrolidone (PVP), multipolymer is as gathering (acrylate-be total to-maleic acid ester), poly-(acrylate-be total to-vinylbenzene) and poly-(ethylene terephthalate-be total to-oxyethane) and their mixture.The example of suitable polymers comprises: Sokalan PA50
TM, Sokalan CP5
TM(the two is available from BASF), Narlex LD 31
TMWith Narlex H1200
TM(the two is available from NationalStarch), Alcosperse 725
TM(available from National Starch), Xylo-Mucine, O14-Methyldelectine, PEG 1500 and Aquaperle (available from ICI).
In addition, the preparation of the method for composition of the present invention visbreaking routinely comprises any combination of following selection or following various selections:
(i) increase electrolytical content in the prescription.A possible shortcoming is that too high electrolyte content can cause physical instability, causes finally genetic horizon separation when storing.There is some method can correct this physical instability, these methods comprise the adding molten ionogen of salt (for example EP-A-0079646), add salt tolerant and analyse tensio-active agent (for example EP-A-0328177) and add deflocculate polymkeric substance (for example EP-A-0346995 and EP-A-0623670).
(ii) reduce surfactant content.
(iii) change the tensio-active agent ratio.For example, in the composition that contains negatively charged ion and nonionogenic tenside, can come visbreaking by the ratio that reduces or increase the anionic/nonionic tensio-active agent.This will depend on the composition situation of prescription, and the best way should be to produce viscosity by aforesaid method to lower.The person skilled in the art can find that adopting the aforesaid method visbreaking is best practical approach with simple experiment.
(iv) change cationic ratio.Usually positively charged ion is sodium and potassium, be three sometimes-or-thanomin.Change positively charged ion, for example increase potassium/sodium ratio, can cause the increase (when the part electrolysis is when existing with crystal) of electrolyte dissolution concentration.This can be by method (i) and/or amount (when dissolving takes place crystal) or visbreaking by reducing solid particulate.
(v) add a small amount of hydrotropic agent, comprise (for example, EP-A-0491 723) such as sodium xylene sulfonate, ethanol, propylene glycol.Hydrotropic amount is too high scarcely, otherwise physical instability will take place product.It is believed that and lower through the viscosity of this method that the flexible increase that is by laminar bilayer causes, this causes the increase of stratiform droplet deformability.Yet, when the amount that hydrotropic agent adds is too many, double-deck integrity forfeiture, the stratiform droplet damages and produces physical instability as a result.
