Description
Invention field
The present invention relates to the aqueous liquid composition, described composition contains a kind of abrasive material and a kind of polymer viscosifier that keeps abrasive material to float on a liquid.
Background technology
Liquid abrasive cleaning composition is well-known in this area, it generally includes the mixture of anion surfactant and nonionogenic tenside, they are common to form a kind of lamellar micelle liquid phase, this lamellar micelle liquid phase as suspension system to keep the solid abrasive stable suspersion.Usually add the stability of a kind of polymer viscosifier with further raising suspension.
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).
Disclosed liquid abrasive cleaning composition contains crosslinked polyacrylic ester, at least a nonionogenic tenside, pH value conditioning agent and a kind of lime carbonate abrasive material among the WO95/08619.Described composition contains the polyacrylic ester of 0.1-2%, the nonionogenic tenside of 0.1-10%, anion surfactant up to 10% and the abrasive material of 5-60%.Disclose similar composition among the EP649898, extra condition is that said composition contains hypochlorite, and tensio-active agent is a bleach tolerant.
Disclosed liquid abrasive cleaning composition contains inorganic abradant and the thickened systems of 10-30% among the WO96/35771, described thickened systems is made up of a kind of crosslinked polyacrylate polymers and a kind of smectite-type clay that accounts for thickened systems 50-80%, and this thickened systems accounts for the 1-2.5% of liquid abrasive cleaning composition.
Disclose liquid abrasive cleaning composition among the EP0301885, described composition contains the abrasive material up to 70%, a kind of by blended anion surfactant, ionogen and molecular weight be the polyacrylic ester of 500-3000 form contain aqueous suspension medium.
Disclose the liquid abrasive cleaning composition that contains a kind of water-soluble abrasive material among the EP0570226, the amount of described water-soluble abrasive material surpasses its solubleness in composition, but is at least 20%.And mention abrasive material and can be tripoly phosphate sodium STPP.Described polymkeric substance also contains at least 0.5% anion surfactant and 1% or the Polyacrylate thickeners of above lower molecular weight (less than 10000).
Disclose a kind of similar products like among the EP0193375, described product contains at least 6% as the water-soluble salt of abrasive material and at least 1.5% the surfactant mixture with structure and suspension property.Described composition can contain according to circumstances up to 10% insoluble abrasive material with as Carbopol
TMThe polymer architecture auxiliary agent.
WO98/49261 discloses liquid abrasive cleaning composition, and described composition contains the suspension system of negatively charged ion and nonionogenic tenside composition.Said composition contains at least 1.0% anion surfactant and at least 0.5% nonionogenic tenside usually.Described composition can contain a kind of as Carbopol according to circumstances
