Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
84 words
A composition for cleaning flooring fouled with oily or greasy soils comprising oil absorbent shreds of a hydrophilic polyurethane foam comprising an open-celled highly reticulated matrix, wherein said matrix incorporates an interior aqueous phase and abrasive particles silane coupled within said matrix and wherein the cells incorporate an absorbed exterior aqueous phase which is partially released from said shreds when the shreds are contacted with the flooring under conditions of pressure wherein in said foam shreds have a particle size of about 5-20 mesh.
Claim 2
Dependent Claim
84 words
A composition for cleaning flooring fouled with oily or greasy soils comprising oil absorbent shreds of a hydrophilic polyurethane foam comprising an open-celled highly reticulated matrix, wherein said matrix incorporates an interior aqueous phase and abrasive particles silane coupled within said matrix and wherein the cells incorporate an absorbed exterior aqueous phase which is partially released from said shreds when the shreds are contacted with the flooring under conditions of pressure wherein in said foam shreds have a particle size of about 5-20 mesh.
Claim 3
Dependent Claim
18 words
The composition of claim 1 wherein the interior aqueous phase comprises a nonionic surfactant and a silicone fluid.
Claim 4
Dependent Claim
28 words
The composition of claim 2 wherein the nonionic surfactant comprises the condensation product of a C 8 -C 22 -alkyl alcohol with about 2-50 moles of ethylene oxide.
Claim 5
Dependent Claim
12 words
The composition of claim 2 wherein the silicon fluid comprises a polydimethylsiloxane.
Claim 6
Dependent Claim
14 words
The composition of claim 1 wherein the interior aqueous phase incorporates an organic solvent.
Claim 7
Dependent Claim
17 words
The composition of claim 1 wherein the foam matrix further incorporates particles of an inorganic suspending agent.
Claim 8
Dependent Claim
14 words
The composition of claim 1 wherein the exterior aqueous phase consists essentially of water.
Claim 9
Dependent Claim
20 words
The composition of claim 7 wherein the exterior aqueous phase comprises about from 2-50% by weight of said foam shreds.
Claim 10
Dependent Claim
27 words
The composition of claim 1 wherein said foam shreds are obtained from a dense, friable foam bun having a tensile strength of less than about 8 psi.
Claim 11
Dependent Claim
19 words
The composition of claim 1 which has a free flow, bulk density within the range of about 0.1-0.6 g/cc.
Claim 12
Dependent Claim
28 words
A method for removing oily or greasy deposits from soiled flooring comprising contacting the surface of the flooring with an effective amount of the composition of claim 1.
