1. A unit dose detergent product comprising:
a unit dose pouch comprising a water soluble film,
a liquid detergent encapsulated in the unit dose pouch, wherein the liquid detergent comprises:
a soil release polymer,
at least 10% by weight of alkyl-ether sulfate (AES) surfactant;
an ethoxylated polyethyleneimine;
a polyethylene glycol (PEG) polymer having a weight average molecular weight of from about 200 to about 1,000 Daltons; and
less than 30% by weight of water,
wherein the liquid detergent composition has a first viscosity at 25 degrees Celsius before further dilution with water and a second viscosity at 25 degrees Celsius after dilution with water at a 2:1 ratio of the liquid detergent to water, wherein a ratio of the first viscosity to the second viscosity is about 1:1 to about 1:3.
