Description

New Cleaning preparations

The present invention relates to new Cleaning preparations, this Cleaning preparations is a single-phase liquid stable, that contain molten washing assistant and concentrated surfactant, and it has the good washing performance.

The stability of the present composition does not rely on the existence of solvent, because may be disadvantageous from the existence of cost or environmental factors solvent.

Liquid washing agent is compared with powder-like product has many superior parts, thereby makes this liquid washing agent occupy sizable ratio in whole detergent market.The introducing that contains than the compact powder of conventional powder greater concn active constituent has proposed challenge to this developing trend of liquid washing agent.Thereby market demand has the product that more thicks liquid to meet this challenge, especially needs to contain to have dissolved or the concentrated aqueous based surfactant compositions of dispersive washing assistant salt, and described composition has low viscosity.

So far, the ability of concentrated liquid detergent is subjected to conventional detergent surfactant system to be higher than 30%(wt in its concentration) form the restriction of this trend of intermediate phase when (in water and tensio-active agent weight).The order degree of intermediate phase or liquid crystal is lower than solid-state but is higher than standardized solution, as at one dimension or sequential 2 D, but is not all orderly in whole three-dimensionals.

As the high extremely about 30%(wt of concentration) time, many tensio-active agents form micellar solution (L ₁-phase), the colloidal ion of tensio-active agent is dispersed in the water in this solution, and they are aggregates of surfactant molecule and it is very little so that invisible under polarimicroscope.The outward appearance of micellar solution is similar to true solution with most of performance.Be about 30%(wt in concentration) time many detergent surfactants form the M-phases, this for having the symmetric liquid crystal of six sides, is generally the waxy substance of stationary phase mutually.This product is not dumpable, and obviously can not be used as liquid washing agent.When being in higher concentration, as be higher than about 50%(wt), normally be in and be higher than 60%, form mobile G-phase more when being lower than 80% a certain concentration range.

G-is non newtonian (shear shinning) mutually, and normally dumpable phase generally has the outward appearance and the flowability of thickness, muddiness and lacteous, and this makes them not attractive and be unsuitable for directly being used as detergent for washing clothes to the human consumer.

In higher concentration, as be higher than about 70% or 80%(wt), most of tensio-active agents form the hydration solids.Under some situation, nonionogenic tenside particularly forms the liquid phase (L of the dispersive micella ionic size that contains water droplet ₂-phase).Have been found that L ₂-be unsuitable for being used as liquid washing agent mutually, because they are difficult for disperseing, and be tending towards forming colloid in water.Can observe but be unsuitable for directly being used as detergent for washing clothes other comprise viscosity isotropy (VI) phase mutually, this is fixed mutually and has transparent outward appearance.

Can discern different phases by the combination of the crystalline structure under outward appearance, rheology, polarimicroscope and the electron microscope and X-ray diffraction or scattering of neutrons.

The out of phase following term that relates to of Tao Luning need make an explanation or define in this manual: " optically-active isotropy " tensio-active agent does not make the face of polarization modulation polarization plane change mutually usually.If a sample is placed between two sheets of polarized material optically-active face, the polarization plane of this material is in correct angle, and light impinges upon on the sheet, and then optically-active isotropy surfactant samples does not seem more a lot of than its bright surroundings when seeing through another sheet observation.It is much bright that the optically-active anisotropic material then will seem.When observing between the quadrature polarizer by microscope, optically-active anisotropy intermediate phase generally all shows its feature, otherwise the optically-active isotropic phase shows a kind of black, undistinguishable substantially continuous spectrum usually.

" Newtonian liquid " viscosity under different shearing rates remains a constant.In the present invention, when shearing rate height to 1000 second ^-1The time does not have obviously to change then as if viscosity, and such fluid is considered to newton's (liquid).

" useful load " of said composition is meant percentages of ingredients, and it is in the gross weight of said composition.The washing effect of the described composition of these components influence, i.e. function ingredients, and it comprises tensio-active agent, washing auxiliary detergent, white dyes, ealkaline buffer, enzyme, anti redeposition agent and defoamer.

" ionogen " is meant and is not tensio-active agent and at any water-soluble cpds of effects of ionization among the present invention.Preferred ionogen is that this electrolysis mass-energy is saltoutd tensio-active agent from solution when itself and tensio-active agent all exist with enough high densitys, is called in the present invention by " tensio-active agent-go solubilising ionogen ".

" soap " refers to C in the present invention ₈-C ₂₂The a kind of of natural or synthetic aliphatic mono carboxylic lipid acid at least can water-soluble on a small quantity salt, and this salt possesses the performance of tensio-active agent.

" washing assistant " refers in the present invention by improving the auxiliary compound that increases the cleaning function of tensio-active agent that is used for of dissolved calcium and/or magnesium.Usually washing assistant also helps to keep the alkalescence of washings.Typical washing assistant comprises sequestering agent and complexing agent, for example tripoly phosphate sodium STPP, potassium pyrophosphate, sodium phosphate, Trisodium Citrate or sodium nitrilo triacetate, ion-exchanger such as zeolite and precipitation agent such as yellow soda ash or potassium, and other alkali as water glass.

Cloth-washing detergent contains tensio-active agent and washing assistant usually.The latter more effectively plays a role tensio-active agent, thereby obviously reduces the consumption of tensio-active agent.The liquid washing agent that adds washing assistant generally contains the washing assistant of about 5-15% tensio-active agent and 10-30%.

When not having washing assistant, may need to use the surfactant detergent that doubles for reaching satisfied effect.Because tensio-active agent is much more expensive than washing assistant, thereby some people thinks that the latter is the essential cost that obtains useful effect.

Managing the subject matter that the solvable washing assistant of containing brings in liquid washing agent is that washing assistant is an ionogen, and they may make tensio-active agent saltout out from solution.The common consequence that adds salting-out electrolyte in the aqueous solution of organic compound is to cause to be separated.This result can observe under the aqueous based surfactant situation usually and obtain, and produces very strong infringement to adding ionogen, even in the concentration that aqueous based surfactant takes place to reduce under enough high densitys that tensio-active agent saltouts probably.For denseer aqueous based surfactant solution, then can produce more intensive infringement to the ionogen that adds with any significant quantity.

There is a special requirement for the concentrated liquid detergent that is applicable to autofeed.These products should have viscosity low, that do not rely on shearing ideally or have Newtonian viscosity, and are easy to be scattered in and do not form the intermediate colloid in the water.This class concentrated liquid detergent is specially adapted to industry and public place user, and the effect of large volume washing composition and the needs of efficient operation generally will cause using automatic metering system.

Generally speaking, commercial liquid laundry detergent is divided into three major types.Liquid laundry detergent the earliest is an aqueous based surfactant, the water-soluble washing assistant salt that only contains lower concentration, and solvent and hydrotropic agent to be to overcome any electrolytical salting out, keeps stable, a non-structure, isotropic water base micellar solution (L simultaneously ₁-phase).The performance of this series products is difficult to compare with powder-like product.By with quite high concentration, as the surfactant concentration height to 60%(by weight), use easier dissolving, but the organic solvent of also more expensive tensio-active agent and abundant consumption is prepared the usefulness of improving every gram product.Because the latter is not contained the washing assistant of high density, the common consumption that contains the product of washing assistant with standard is compared, and they must be with higher consumption batching to obtain comparable properties.The tensio-active agent that higher consumption consequently is provided in washing water is to remedy the shortage of washing assistant.In addition, more easily molten tensio-active agent is poorer as washing composition effect trend.Therefore, its benefit in general with regard to required condition is very few, and the soluble surfaces promoting agent than high cost and keep the required solvent expense (these two kinds of ways are helpless to washing functions) of each homogeny composition of homogeneous phase to deepen higher relatively this defective of the required expense of each washing, to wash consumption big but existence tensio-active agent batching poor efficiency relatively and solvent also is disadvantageous for environment at every turn.

The improvement of second type liquid washing agent makes aqueous detergent compositions solid detergent can be suspended in the water of constitution based surfactants system as tripoly phosphate sodium STPP or zeolite.Usually can form surfactant structure by dissolved ionogen and Action of Surfactant.Thereby tensio-active agent saltouts out from the isotropy micellar phase and aqueous electrolyte forms the dispersive intermediate phase.All body structure surface active agent systems all show the viscosity that depends on shearing.If this system can suspended solids and do not had sedimentary danger then non--Newtonian viscosity is essential, but when planning that this product is used for the industry that need be used with automatic feeding system or public purpose, non--Newtonian viscosity then is a deficiency.

The washing composition of the third type in up-to-date introducing market is an anhydrous type.Its advantage is high surface agent concentration and the ability that is difficult to be included in the containing oxidative bleaching agent in the water-based formulation usually.Yet existing anhydrous formulations contains a large amount of organic solvents that may cause criticism on environmental problem, and such formulation product is difficult to be diluted to washings concentration.The adding of water is tending towards causing that colloidal forms.Surfactivity may be seen the danger that excessively feeds intake from the high density of agent.The stability in storage of this class washing composition is very poor usually in addition.

An object of the present invention is to provide the cloth-washing detergent that thicks liquid relatively, as contain 35% or higher effective ingredient (comprising tensio-active agent and dissolved washing assistant), this washing composition is isotropy (L in the presence of no opalizer ₁-phase).A special purpose of the present invention provides such based composition, this based composition does not need the necessary solvent that does not conform with environmental requirement of concentrated liquid detergent up to now, or expensive stablizer or the existence that expends the tensio-active agent of height and poor efficiency relatively.
