US Patent No. 9,771,546 B2; The Procter & Gamble Company has patented a laundry detergent composition that contains cationic polymer, a silicone and a surfactant system. The cationic polymer is comprised of a structural unit derived from (meth)acrylamide, and a second structural unit derived from diallyl dimethyl ammonium chloride (DADMAC). The cationic polymer is characterized by a molecular weight of from about 10 kDaltons to about 150 kDaltons.
P&G has also been awarded a patent (US Patent No. 9,771,551 B2) for a liquid cleaner with abrasives. It contains abrasive cleaning particles comprised of a biodegradable thermoplastic material selected from the group consisting of biodegradable petroleum-based polyesters, thermoplastic starch, cellulose esters, and mixtures thereof (said biodegradable petroleum-based polyesters selected from the group consisting of polyesteramide, aliphatic copolyesters, aromatic copolyesters, and mixtures thereof); one or more surfactants selected from the group consisting of anionic, nonionic, cationic, amphoteric and mixtures thereof; and a first acidic component that consists of one or more chelating acids.
