Abstract
The present invention relates to laundry detergent compositions which provide enhance hydrophilic soil cleaning benefits, said compositions comprising: a) from about 0.01% by weight, of a zwitterionic hexamethylene diamine; b) from about 0.01% by weight, of a surfactant system comprising one or more surfactants selected from the group consisting of nonionic, anionic, cationic, zwitterionic, ampholytic surfactants, and mixtures thereof; and c) the balance carriers and adjunct ingredients. The preferred embodiment of the present includes laundry detergent compositions in the form of a water soluble or dispersible tablet.

A granular laundry detergent composition comprising:
- a) from about 0.01% to about 20% by weight, of a zwitterionic hexamethylene diamine having the formula:
- wherein R is an alkyleneoxy unit having the formula:
- —(R1O)xR2

- Q is a quaternizing unit independently selected from the group consisting of C1-C8 linear alkyl, C3-C8 branched alkyl, benzyl, and mixtures thereof;
- X is a water soluble anion in sufficient amount to provide electronic neutrality;
- b) from about 0.01% to about 80% by weight, of a surfactant system comprising one or more surfactants selected from the group consisting of nonionic, anionic, cationic, zwitterionic, ampholytic surfactants, and mixtures thereof;
- and
- c) the balance carriers and adjunct ingredients.

- c) from about 1% to about 80% by weight, of a detergent builder;
- d) from about 0.1% to about 15% by weight, of a binder or processing aid;
- and
- e) the balance carriers and adjunct ingredients.
A method for removing hydrophilic soils for fabric comprising the step of contacting fabric with a composition comprising:
- a) from about 0.01% to about 20% by weight, of a zwitterionic hexamethylene diamine having the formula:
- wherein R is an alkyleneoxy unit having the formula:
- —(R1O)xR2
- wherein R1 is C2-C4 linear alkylene, C3-C4 branched alkylene, and mixtures thereof;
- R2 is hydrogen, an anionic unit, and mixtures thereof;
- the index x has the value of from about 15 to about 35;
- Q is a quaternizing unit independently selected from the group consisting of C1-C8 linear alkyl, C3-C8 branched alkyl, benzyl, and mixtures thereof;
- X is a water soluble anion in sufficient amount to provide electronic neutrality;
