ABSTRACT:

TECHNICAL FIELD
This application relates to detergent compositions containing a soil entrainment system. The detergent composition cleaning solution is also preferably suitable for use with a disposable cleaning pad. This application also relates to a process of using the detergent composition with such a cleaning pad, and the provision of a kit containing the detergent composition and cleaning pad are disclosed.
BACKGROUND OF THE INVENTION
The developer and formulator of surfactants for hard surface cleaning must consider a wide variety of possibilities with limited (sometimes inconsistent) information, and then strive to provide overall improvements in one or more of a whole array of criteria, including performance in the presence of free calcium and a wide variety of soils, in complex mixtures of surfactants and polymers, e.g. cationic polymers, formulation changes, enzymes , various changes in consumer habits and practices, and the need for biodegradability.
One particularly problematic area is that of the different types of soils. Particulate soils, such as clay, sand, dirt, lint, humic soils, and silicates, are especially problematic. The difficulty with particulate soils is not their dissolution, but rather their removal from the surface. In no rinse situations the particulate soils are suspended, but reappear upon drying as streaking and hazing on the “cleaned surface”. Alternatively, rinsing the surface after suspending the particulate soil is not a realistic option, either because of the nature of the surface, e.g. wood which is easily damaged by water, or the impracticality and possible hazards of using large volume of water in cleaning household surfaces near electrical appliance. Wiping the surface with a cloth, sponge mop or the like at best can remove some of the particulate soil. At worst merely redistributing the particulate soil over the surface being cleaned. Floors are particularly susceptible to this redistribution, as the solutions used traditional cleaning methods, i.e. mop with dilute cleaning solution in a bucket, effectively become “dirty water” after a limited application of the mop and solution to the surface. This either require frequent stoppages to refresh the cleaning solution, or that the consumer tolerate surfaces which are streaked and hazy.
Consequently, there remains the need for a hard surface cleaning composition which can readily and conveniently remove particulate soil from a hard surface and prevent their redeposition, without the use of rinsing.
SUMMARY OF THE INVENTION
The present invention meets the aforementioned needs in that it has been surprisingly discovered that a soil entrainment system traps the particulate soil facilitating its removal from the surface, eliminating the need for rinsing the surface.
A first aspect of the present invention relates to an aqueous hard surface cleaning composition that provides effective cleaning and good filming streaking, in combination with a disposable cleaning pad, said combination being suitable for use without rinsing wherein said composition comprises:
a) an effective amount of a soil entrainment system, said soil entrainment system is selected from the group consisting of
1) one or more modified polyamine compounds, said modified polyamine compounds are selected from:
i) (PA)

ii) (PA)

iii) [(PA)

; and
iv) mixtures thereof;
 wherein PA is a grafted or non-grafted, modified or unmodified polyamine backbone unit, T is an amide-forming polycarboxylic acid crosslinking unit, and L is a non-amide forming crosslinking unit; provided that for compounds of type (i) and (iii) the indices w and x have values such that the ratio of w to x is from 0.8:1 to 1.5:1; for compounds of type (ii) the indices w and z have values such that said modified polyamine compound comprises from about 0.05 to about 2 parts by weight of said L unit; for compounds of type (iii) the indices y and z have values such that said modified polyamine compound comprises from about 0.05 to about 2 parts by weight of said L unit; and
2) polyethylene glycols with an average molecular weight of from about 400,000 daltons to about 15,000,000 daltons;

b) the balance adjunct ingredients;
wherein said composition has a pH under usage conditions of from about 2 to about 12.
