Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
145 words
A liquid detergent composition comprising by weight: (a) from about 15% to about 50% of an anionic surfac-tant (b) from about 2% to about 15% of a suds stabilizing nonionic surfactant selected from the group con-sisting of amine oxides, amides and the ethylene oxide condensates of alcohols and alkyl phenols; (c) from about 1% to about 20% of a water-insoluble abrasive having a particle diameter of from about 5 to 250 microns and a hardness on the Mohs scale of from about 2 to about 8; and (d) from about 20% to about 82% water; said composition providing an initial suds cover to a dish-washing solution and a suds cover after the washing of eight plates when used at a concentration of 0.07% in two gallons of 115°F. water containing 7 grains/gallon water hardness measured as CaCO3, each plate carrying 4.0 ml. of triglyceride-containing soil.
Claim 2
Dependent Claim
