Abstract:
1. A method of manually cleaning dishware using a liquid hand dishwashing detergent composition, the method comprising: providing a liquid hand dishwashing composition having a total weight and including from about 4% to about 40% of the total weight anionic surfactant, between 0.01% and 20% of the total weight amine oxide or betaine, a total level of surfactants by weight of between about 1.0% and about 50%, and between about 0.001 wt % to about 10 wt % a cationic polymer having an average molecular weight between about 350,000 and about 2,100,000; and a cationic charge density above or equal to about 0.45 meq/g, wherein the cationic polymer is a guar hydroxypropyl trimonium chloride and wherein said composition has a coacervation index upon dilution of at least about 6%; diluting the detergent composition in water; forming a coacervate of the cationic polymer and the surfactant in the water such that the coacervate is available to contact the skin of a user when the user is manually cleaning the dishware; and exposing the dishware and the user's skin to the diluted detergent composition.
