Abstract

The present invention relates to detergent or cleaning compositions with improved sudsing profile, which comprise a cationic polymer, an organomodified silicone and a siloxane-based diluent.

2 . The detergent or cleaning composition of claim 1 , wherein said cationic polymer comprises from 5 mol % to 99 mol %, preferably from 15 mol % to 98 mol %, more preferably from 30 mol % to 97 mol %, and most preferably from 60 mol % to 96 mol %, of said first nonionic structural unit.

3 . The detergent or cleaning composition of claim 1 , wherein the second cationic structural unit of the cationic polymer is derived from a monomer selected from the group consisting of diallyl dimethyl ammonium salts (DADMAS), N,N-dimethyl aminoethyl acrylate, N,N-dimethyl aminoethyl methacrylate (DMAM), [2-(methacryloylamino)ethyl]tri-methylammonium salts, N,N-dimethylaminopropyl acrylamide (DMAPA), N,N-dimethylaminopropyl methacrylamide (DMAPMA), acrylamidopropyl trimethyl ammonium salts (APTAS), methacrylamidopropyl trimethylammonium salts (MAPTAS), quaternized vinylimidazole (QVi), and combinations thereof, and preferably said second cationic structural unit is derived from diallyl dimethyl ammonium chloride (DADMAC).

4 . The detergent or cleaning composition of claim 1 , wherein said cationic polymer comprises from 1 mol % to 99 mol %, preferably from 2 mol % to 80 mol %, more preferably from 3 mol % to 60 mol %, and most preferably from 4 mol % to 40 mol %, of said second cationic structural unit.

5 . The detergent or cleaning composition of claim 1 , wherein said cationic polymer further comprises a third nonionic structural unit derived from a monomer selected from the group consisting of vinylpyrrolidone (VP), vinyl acetate, vinyl alcohol, vinyl formamide, vinyl acetamide, vinyl alkyl ether, vinyl pyridine, vinyl imidazole, vinyl caprolactam, and combinations thereof, and preferably said third nonionic structural unit is derived from VP.

6 . The detergent or cleaning composition of claim 5 , wherein said cationic polymer comprises from 0 mol % to 95 mol %, preferably from 0 mol % to 90 mol %, and more preferably from 0 mol % to 85 mol %, of said third nonionic structural unit.

7 . The detergent or cleaning composition of claim 1 , wherein said cationic polymer is present in an amount ranging from 0.005% to 10%, preferably from 0.01% to 5%, more preferably from 0.05% to 3%, and most preferably from 0.1% to 1% by total weight of the detergent or cleaning composition.

8 . The detergent or cleaning composition of claim 1 , wherein the aromatic ring of said one or more aryl moieties in said organomodified silicone is selected from the group consisting of phenyl, furan, pyrrole, thiophene, imidazole, pyrazole, oxazole, pyridine, pyrazine, naphthalene, anthracene moieties, and derivatives thereof, and preferably said one or more aryl moieties are selected from alkylphenyl moieties, and more preferably said one or more aryl moieties are 2-phenylpropyl moieties.

9 . The detergent or cleaning composition of claim 1 , wherein said organomodified silicone further comprises one or more C 2 -C 20 aliphatic moieties, and preferably said one or more C 2 -C 20 aliphatic moieties are C 6 -C 10 alkyl moieties.

10 . The detergent or cleaning composition of claim 1 , wherein said organomodified silicone comprises from 1 mol % to 75 mol %, preferably from 5 mol % to 50 mol %, and more preferably from 10 mol % to 40 mol %, of siloxane units containing a 2-phenylpropyl moiety; and from 1 mol % to 20 mol %, preferably from 2 mol % to 15 mol %, and more preferably from 3 mol % to 10 mol %, of siloxane units containing a C 3 -C 30 aryl moiety.
