Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 155 words
A powdered cleaning composition having a soil substantivity constant greater than 1.5 and consisting essentially of: (a) about 100 parts by weight particulate urea-formaldehyde polymeric material having an average particle size of from about 10 to about 105 microns in diameter, an oil absorption value of no less than 90, fiber hardness, and a bulk density of at least about 0.2 g/cc; (b) from about 5 to about 400 parts by weight of an inorganic salt adjuvant selected from sulfates, chlorides, carbonates, bicarbonates, borates, citrates, phosphates, nitrates, metasilicates and mixtures thereof, having an average particle size of from about 45 to about 600 microns in diameter; and (c) from about 5 to about 400 parts by weight of a fluid consisting essentially of 0 to 100 percent water containing sufficient surfactant to give a surface tension of less than about 40 dynes per centimeter and 100 to 0 percent of a high boiling hydrocarbon solvent.
Claim 2
Dependent Claim 155 words
A powdered cleaning composition having a soil substantivity constant greater than 1.5 and consisting essentially of: (a) about 100 parts by weight particulate urea-formaldehyde polymeric material having an average particle size of from about 10 to about 105 microns in diameter, an oil absorption value of no less than 90, fiber hardness, and a bulk density of at least about 0.2 g/cc; (b) from about 5 to about 400 parts by weight of an inorganic salt adjuvant selected from sulfates, chlorides, carbonates, bicarbonates, borates, citrates, phosphates, nitrates, metasilicates and mixtures thereof, having an average particle size of from about 45 to about 600 microns in diameter; and (c) from about 5 to about 400 parts by weight of a fluid consisting essentially of 0 to 100 percent water containing sufficient surfactant to give a surface tension of less than about 40 dynes per centimeter and 100 to 0 percent of a high boiling hydrocarbon solvent.
Claim 3
Dependent Claim 103 words
A powdered cleaning composition containing 100 parts by weight of particulate urea-formaldehyde polymeric material having an average particle size of from about 37 to about 105 microns; from about 5 to about 400 parts by weight of an inorganic salt adjuvant selected from sulfates, chlorides, carbonates, bicarbonates, borates, citrates, phosphates, nitrates, metasilicates, and mixtures thereof, and from about 5 to about 400 parts by weight of fluid component consisting essentially of 0 to 100 percent water containing sufficient surfactant to give a surface tension of less than about 40 dynes per centimeter and 100 to 0 percent of a high boiling hydrocarbon solvent.
Claim 4
Dependent Claim 103 words
A powdered cleaning composition containing 100 parts by weight of particulate urea-formaldehyde polymeric material having an average particle size of from about 37 to about 105 microns; from about 5 to about 400 parts by weight of an inorganic salt adjuvant selected from sulfates, chlorides, carbonates, bicarbonates, borates, citrates, phosphates, nitrates, metasilicates, and mixtures thereof, and from about 5 to about 400 parts by weight of fluid component consisting essentially of 0 to 100 percent water containing sufficient surfactant to give a surface tension of less than about 40 dynes per centimeter and 100 to 0 percent of a high boiling hydrocarbon solvent.
Claim 5
Dependent Claim 23 words
The cleaning composition of claim 1, wherein the average particle size of the polymeric material is from about 35 to about 105 microns.
Claim 6
Dependent Claim 14 words
The cleaning composition of claim 1, wherein said inorganic salt adjuvant is a borate.
Claim 7
Dependent Claim 14 words
The cleaning composition of claim 2, wherein said inorganic salt adjuvant is a borate.
