First claim

The invention claimed is:

1. A liquid laundry detergent composition for clothing consisting of:
a bacteria-eliminating active agent,
at least one cationic polymer selected from components (a), (b) and (c),
a surfactant, and
optionally one or more water-soluble solvents, alkali agents, metal scavengers, anti-recontamination materials, antioxidants, rust inhibitors, preservatives, colorants, coloring agents, and perfumes;
wherein the component (a) is a polymer having a constitutional unit selected from formulas 1, 2, 3, 4 and salts thereof;
the component (b) is a copolymer having a constitutional unit selected from formula 5 and salts thereof and a constitutional unit selected from formulas 1, 2, 3, 4 and salts thereof; and
the component (c) is a polymer having a constitutional unit selected from formula 6 and salts thereof, or a copolymer having a constitutional unit selected from formula 6 and salts thereof and a constitutional unit selected from formulas 1, 2, 3, 4 and salts thereof:

wherein X represents

R 1 represents a hydrogen atom, an alkyl group having 1 to 3 carbon atoms or a hydroxyl group;
R 2 and R 3 independently represent an alkyl or hydroxylalkyl group having 1 to 3 carbon atoms;
Z − represents a halogen ion, a sulfate ion, an alkyl sulfate ion having 1 to 3 carbon atoms, an aromatic sulfonate ion or a hydroxyl ion;
R 4 represents a hydrogen atom or an alkyl group having 1 to 3 carbon atoms;
A represents —NH 2 , —OM, —OR 5 or —NR 6 R 7 ;
M represents a monovalent cation;
R 5 represents an alkyl group having 1 to 24 carbon atoms;
R 6 and R 7 independently represent an alkyl or hydroxylalkyl group having 1 to 3 carbon atoms; and
n is an integer between 1 and 3,000; and

wherein the bacteria-eliminating active agent is at least one selected from the group consisting of a guanidine compound, an imidazolium salt derivative, and a bis(aminoalkyl)alkylamine compound.

2. The liquid laundry detergent composition for clothing according to claim 1 , wherein the bacteria-eliminating active agent is at least one selected from the group consisting of:
a polyaminopropyl guanidine compound; an imidazolium salt derivative selected from the group consisting of 1,10-di(3-decyl-2-methylimidazolium)decane dichloride, 1,10-di(3-decyl-2-methylimidazolium)decane dibromide, 1,12-di(3-decyl-2-methylimidazolium)dodecane dichloride, 1,12-di(3-octyl-2-methylimidazolium)dodecane dichloride, and 1,10-di(3-decyl-2-methylimidazolium)decane dichloride; and bis(aminopropyl)dodecylamine.

3. The liquid laundry detergent composition for clothing according to claim 1 , wherein the bacteria-eliminating active agent includes at least one member selected from the group consisting of:
a polyaminopropyl guanidine hydrochloride and bis(aminopropyl)dodecylamine.

4. The liquid laundry detergent composition for clothing according to claim 1 , comprising:
the bacteria-eliminating active agent in an amount between 0.1% by weight and 20% by weight,
the at least one cationic polymer selected from the components (a), (b) and (c) in an amount between 0.1% by weight and 20% by weight, and
the surfactant in an amount between 5% by weight and 90% by weight.
