Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
82 words
A composition for cleaning flooring of soiled wax deposits and depositing a fresh coating of wax thereupon comprising moist shreds of a hydrophilic polyurethane foam comprising an open-celled highly reticulated matrix, wherein said matrix incorporates an interior aqueous phase and an effective scouring amount of abrasive particles silane coupled within said matrix, and wherein said shreds incorporate a wax which is partially released from said shreds as an aqueous emulsion when the shreds are contacted with the flooring under conditions of pressure.
Claim 2
Dependent Claim
82 words
A composition for cleaning flooring of soiled wax deposits and depositing a fresh coating of wax thereupon comprising moist shreds of a hydrophilic polyurethane foam comprising an open-celled highly reticulated matrix, wherein said matrix incorporates an interior aqueous phase and an effective scouring amount of abrasive particles silane coupled within said matrix, and wherein said shreds incorporate a wax which is partially released from said shreds as an aqueous emulsion when the shreds are contacted with the flooring under conditions of pressure.
Claim 3
Dependent Claim
15 words
The composition of claim 1 wherein the wax is emulsified in the interior aqueous phase.
Claim 4
Dependent Claim
25 words
The composition of claim 1 wherein the wax is emulsified in an exterior aqueous phase which is absorbed into the cells of the foam shreds.
Claim 5
Dependent Claim
12 words
The compositions of claims 2 and 3 wherein the wax comprises polyethylene.
Claim 6
Dependent Claim
24 words
The composition of claim 3 wherein the weight ratio of exterior aqueous phase-wax emulsion comprises from about 20-40% by weight of said foam shreds.
Claim 7
Dependent Claim
18 words
The composition of claim 1 wherein said interior aqueous phase comprises a nonionic surfactant and a silicone oil.
Claim 8
Dependent Claim
45 words
The composition of claim 6 wherein the nonionic surfactant comprises the condensation product of a polyoxypropylene ether and a polyoxyethylene ether wherein the polyoxypropylene ether has a molecular weight of about 1500-3000 and the polyoxypropylene content is about 35-55% by weight of the surfactant molecule.
Claim 9
Dependent Claim
12 words
The composition of claim 6 wherein the silicone oil comprises a polydimethylsiloxane.
Claim 10
Dependent Claim
15 words
The composition of claim 1 wherein the interior aqueous phase further comprises an organic solvent.
Claim 11
Dependent Claim
30 words
A method of removing soiled wax from flooring and applying a fresh coating of wax thereto, comprising contacting the flooring with an effective amount of the composition of claim 1.
