The on-liquid abrasive cleaning composition also is known.The form that these compositions are taked has pasty state, gel and powdery.These compositions can comprise tensio-active agent, can comprise the water of relative low levels.Be used for the typical abrasive material of these compositions and comprise calcite and rhombspar.
The invention summary
We have now determined the C with significant quantity 2-C 6Alkanolamine and a kind of ionogen alkali except that alkanolamine can be prepared the on-liquid scrubbing agent through improving.The existence of alkanolamine is needed, because when owing to alkali the pH value being raise, alkanolamine not only can be used as solvent, and can be used as other alkali and assist in removing ticklish dirt.Thereby the invention provides the scrubbing agent of a kind of effective cleaning and stable storing.Detailed Description Of The Invention
The invention provides a kind of on-liquid abrasive cleaning composition, it comprises
A) one or more abrasive granules of 50-99.5% weight,
B) C of 0.5-15% weight 2-C 6Alkanolamine,
C) the ionogen alkali except that alkanolamine of at least 0.1% weight,
D) one or more tensio-active agents of optional 0.1-20% weight and
E) optional 0.1-20% weight dewater or alkanolamine outside solvent.
Should think that in the presence of water, in use promptly, the combination of alkali and alkanolamine can improve cleaning action.
The present invention also provides a kind of light dirt to clean (being dishwashing detergent) method, and this method comprises the treatment step with composition cleaning objects disclosed herein.
On-liquid scrubbing agent related products form is pasty state, gel or powdery within the scope of the present invention.Abrasive material
According to the present invention, abrasive granule is the necessary component of composition mutually.
Particle preferably includes water-fast abrasive granule mutually.In addition, abrasive material can also be soluble, and in the excessive water that is present in composition, is containing the solubleness of aqueous phase so that surpass abrasive material, has solid abrasive in the composition thereby make.
Suitable abrasive material can be selected from granular zeolite, calcite, and rhombspar, feldspar, silica, silicate, other carbonate, aluminum oxide, supercarbonate, borate, vitriol, and polymkeric substance are as polyethylene.
It is 2-6 that the abrasive material that is preferred for common purposes composition has Mohs' hardness, can use the abrasive material of higher hardness certainly for specialized application.
Average (weight average) particle diameter of preferred abrasive material is the 0.5-400 micron, and its value is preferred at about 10-200 micron.In this scope, can reach good cleaning performance and substrate is hanged down acceptable compromise proposal between the damage.
Preferred abrasive material content range is a 60-95% weight in the product, preferable range 65-90% weight.The influence of the abrasive material content that the physical form of product will be existed.In general, the composition with higher abrasive material content is a powdery, and have a lower aq those be pasty state.Say exactly, make the abrasive granule product when powdery becomes pasty state, be subjected to the influence of other component when the abrasive granule that exists reduces with content.As can be seen, if when abrasive material content is lower than 80-90% weight, composition becomes pasty state from the following description of the present invention preferred embodiment.
The physical stability of mashed prod can improve by there being high-load abrasive material.In this case, high-load abrasive material is greater than 80% of composition total weight.
Most preferred abrasive material is lime carbonate (calcite), the mixture of lime carbonate and magnesiumcarbonate (rhombspar), sodium bicarbonate, vitriolate of tartar, zeolite, aluminum oxide, hydrated aluminum oxide, feldspar, talcum and silica.
Calcite, feldspar and rhombspar and their mixture are particularly preferred because low, hardness of its cost and color and luster are suitable.Alkanolamine

These results show that the use of salt of wormwood can be anhydrous form or hydrated form.Yet should be pointed out that when using the carbonate of low levels using salt hydrate is not to negate need add entry to make the sample thickening.
Example 5: use different abrasive materials
The pH value of 50% slip of test case P2 and 2% water in several weeks, is measured the pH value of the slip of each prepared fresh then at the beginning.The pH value that records the sample that contains water after several weeks reduces.
The abrasive material of P2 is changed to feldspar (potassium aluminosilicate).Water with 2% adds in the sample, and monitors its pH value as mentioned above.The pH value of initial two samples is 11.9.The pH value that does not add the water sample after 10 days is 11.7, and the pH value that adds the water sample is 11.8.Thereby the decline of pH value do not appear.
Example 6: whipability
Preparation has the example of table 7 prescription.The whipability of evaluation example as shown in table 8.

Be the test whipability, with 1: 4 Prenton water: the mixture of softening water, its final water hardness～5 H, it is 0.04% actives that tested sample is diluted.The sample of dilution is 45 ℃ of insulations down.The 100ml sample is put into the plunger cylinder, and add branch sample such as standard dirt 0.2ml up to lather collapse.Measure and just " kill " the needed five equilibrium sample of foam quantity.Each sample testing 4 times calculates average and standard deviation.
