Description

Liquid abrasive cleaning composition
Invention field
The present invention relates to the aqueous liquid composition, said composition contains a kind of abrasive material and a kind of polymeric viscosifier, so that abrasive material floats on a liquid.
Background of invention
Liquid abrasive cleaning composition is well-known in this area, and it mainly comprises blended detergent surfactant, particularly negatively charged ion and nonionogenic tenside, and these tensio-active agents form the stratiform micellar phase together, therefore makes the liquid thickening.This lamellar phase is as suspension system, to keep the solid abrasive stable suspersion.Usually add the stability of a kind of ionogen with further improvement suspension.
Yet detergent surfactant is very expensive composition, and except its thickening and suspension effect, it is not clear whether they very can increase the cleaning efficiency of composition.Thereby done the consumption that various effort reduce tensio-active agent, and keep necessary thickening of abrasive material stable suspersion and suspending power to provide by adding polymeric viscosifier.
Thereby disclosed liquid abrasive cleaning composition contains the washing composition of 0.02-20% among the WO91/08283, the thickened mixt that the abrasive granule of 1-70% and 0.01-10% are made up of non-starch-type polymkeric substance of straight chain and amylopectin type polymkeric substance (amylopectin).Non-starch-type polymkeric substance comprises various natural gums and synthetic polymer.The xanthan gum of preferred especially partial acetylation.The amount of in fact needed thickened mixt approximately is 3% of a composition total weight, and all embodiment specify 1.5% nonionogenic tenside.
Disclosed liquid abrasive cleaning composition contains crosslinked polyacrylic ester among the WO95/08619, perhaps at least a nonionogenic tenside, perhaps blended anion surfactant and nonionogenic tenside, pH value conditioning agent, and lime carbonate abrasive material.Described composition contains the polyacrylic ester of 0.1-2%, the nonionic of 0.1-10%, the negatively charged ion up to 10% and the abrasive material of 5-60%.In fact, according to embodiment, they contain the 0.25-0.4% polymkeric substance, and 0.5% or more nonionic and 40% abrasive material.Nonionic is wanted suitable viscosity characteristics can be provided.EP649898 discloses similar composition, and extra condition is that said composition contains hypochlorite and tensio-active agent is anti-bleaching.
Disclosed liquid abrasive cleaning composition contains inorganic abradant and the thickened systems of 10-30% among the WO96/35771, this system is made up of at least a crosslinked polyacrylate polymers and a kind of smectite-type clay, and the latter is preferably formed the thickened systems of about 50-80% thus.This thickened systems preferably accounts for the composition of 1-2.5%.In fact all cleaning compositions all contain at least 0.5 polyacrylic ester and at least 0.75% clay.
EP0352358 has described very thin silica-based powder suspension thing such as zeolite, this suspended substance comprises and has hydroxyl and the molecular weight compound as the organic polymer of suspension agent more than 1500, and requires to exist certain positively charged ion or zwitterionics as stablizer.The particle diameter of zeolite to be suspended is generally at 0.5-10 μ m, and most of raw material has the following particle diameter of 6 μ m.Cited unique polymkeric substance is blended guar gum and xanthan gum.
A kind of moisture thickener composition that is fit to each terminal applies has been described among the EP-A-0875557, said composition contains at least two kinds of surfactant mixtures with specific proportions of 0.04-30% w/w, and the HLB value of two kinds of tensio-active agents differs at least 1 unit, and the associative thickeners of the alkali-soluble emulsion polymkeric substance of the nonionic polyvalent alcohol of the Natvosol that is selected from hydrophobically modified of 0.01-5% w/w, hydrophobically modified and hydrophobically modified.In fact the amount of associative thickeners is 1-2%, and the amount of tensio-active agent is 1-10%.
EP0301885 discloses liquid abrasive cleaning composition, and said composition contains abrasive material up to 70%, contains aqueous suspension medium by what blended anion surfactant and ionogen were formed, and also containing molecular weight is the polyacrylic ester raw material of 500-3000.In fact said composition contains at least 3.5% tensio-active agent.
The solid abrasive that contains 10-50%, general 20-45% under the normal circumstances with the liquid abrasive cleaning composition of available form sale at any time.Such composition can not be diluted to the solid abrasive content of 10-20% for example and do not lose they stability, cause sedimentation.Though the abrasive material content of quoting in the patent documentation up to 70%, is such content can not occur in commodity under the normal circumstances.
The invention summary
An object of the present invention is to provide stable aqueous liquid abrasive cleaning composition, said composition does not need detergent surfactant to obtain stable suspersion.
Another object of the present invention provides liquid aqueous abrasive cleaning composition, and abrasive material is suspended in the polymeric viscosifier.
A further object of the invention provides moisture abrasive cleaning composition, and said composition or provide with ready-to-use form perhaps provides with spissated form, by the human consumer it is diluted to ready-to-use product, and don't loses permanent stability.
Therefore, the invention provides liquid aqueous abrasive cleaning composition, said composition comprises insoluble abrasive material and negatively charged ion thickening polymer.
Detailed Description Of The Invention
All percentage ratios given herein all are based on the gross weight of composition, unless otherwise specified.Term " liquid state " relates to the product that pours into easily as used herein, also relates to thickness, almost is the product of pasty state, but because its flowability physically still is categorized as liquid state with it.
Aqueous liquid abrasive cleaning composition of the present invention contains the solid abrasive of 10-95%, the negatively charged ion thickening polymer of 0.05-0.70% and be not more than 1.0% tensio-active agent.
According to the present invention, the solid-state abrasive granule of dispersive, suspension is the important component of liquid abrasive cleaning composition.The amount of Preferred abrasives is at least 20%, generally is not more than 80% for practical purposes, more preferably maximum 75%.
Can and be packaged into ready-to-use composition with this product preparation with above-mentioned special abrasive material content.That such composition can have is thick, sticking, the form of pasty product almost, perhaps they can have the liquid form that pours into easily, the product of this liquid form is easy to distribute from the bottle that has relative slot, and similar to well-known existing commodity " liquid abrasive cleaning " in appearance.Ready-to-use accompanied with sticky product preferably has high abrasive material content, and at least 45%, more preferably greater than 50%, even more preferably at least 55%, most preferably at least 60%.On the other hand, pourable ready-to-use liquid-type composition preferably has low abrasive material content, that is to say to be lower than 55% more preferably 50% or still less, even more preferably maximum 45%.
Perhaps can and be packaged into enriched material, before using, dilute this enriched material by adding an amount of water with composition preparation of the present invention.For the same finally ready-to-use product of content, the advantage that such composition has is that they only need littler packing, and this provides convenience just for storage and transportation.Can with they as intermediates in batches production and be transported to production facility near the human consumer, here water dilutes them, sells with its packing and as ready-to-use product then.On the other hand, also can be with they direct packings, sell as enriched material, by human consumer's dilute with water of staying at home.
These products also have high abrasive material content, and preferably at least 45%,, more preferably greater than 50%, even more preferably at least 55%, most preferably at least 60%.
But Preferred abrasives has less than 6 greater than 1 Moh hardness, though can use the higher hardness abrasive material for special applications.Preferred hardness is at least 2.
