Abstract
A method for controlling rheology of a unit dose liquid detergent composition includes providing a detergent composition containing less than 20% water, a detergent surfactant, and a rheology modification system comprising iminodisuccinic acid (IDS), ethanol, and polyethylene glycol having a molecular weight of 200 to 1,000 Daltons; and encapsulating the detergent composition in a pouch made of a water soluble film. The viscosity of a mixture of 2 parts of a low water detergent composition to 1 part water can be maintained below 1,000 cp at 1.08 reciprocal seconds where the detergent composition includes about 1% to about 10% by weight of a mixture of IDS, ethanol, and polyethylene glycol having a molecular weight of 200 to 1,000 Daltons.
