Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
174 words
An aqueous false-body hard-surface scouring cleanser consisting essentially of: A. from about 0.2% to 5% by weight of a bleaching agent which yields hypochlorite ion in aqueous solution; B. from about 1% to 30% by weight of an inorganic colloid-forming clay selected from the group consisting of smectites, attapulgites and mixtures of smectites and attapulgites; C. from about 0.1% to 5% by weight of a paraffin sul-fonate surfactant of the formula RSO3M wherein R is a primary or secondary alkyl group containing from about 8 to about 22 carbon atoms and M is an alkali metal; D. from about 5% to about 60% by weight of insoluble particulate abrasive material which has particle diameters ranging from one micron to about 250 microns and a specific gravity of from about 0.2 to about 5.0; E. from about 2% to about 15% by weight of an inorganic alkaline buffer salt capable of maintaining composition pH within the range of from about 10.0 to 14; and F. from about 10% to about 90% by weight of water.
Claim 2
Dependent Claim
174 words
An aqueous false-body hard-surface scouring cleanser consisting essentially of: A. from about 0.2% to 5% by weight of a bleaching agent which yields hypochlorite ion in aqueous solution; B. from about 1% to 30% by weight of an inorganic colloid-forming clay selected from the group consisting of smectites, attapulgites and mixtures of smectites and attapulgites; C. from about 0.1% to 5% by weight of a paraffin sul-fonate surfactant of the formula RSO3M wherein R is a primary or secondary alkyl group containing from about 8 to about 22 carbon atoms and M is an alkali metal; D. from about 5% to about 60% by weight of insoluble particulate abrasive material which has particle diameters ranging from one micron to about 250 microns and a specific gravity of from about 0.2 to about 5.0; E. from about 2% to about 15% by weight of an inorganic alkaline buffer salt capable of maintaining composition pH within the range of from about 10.0 to 14; and F. from about 10% to about 90% by weight of water.
