Use of tertiary amine to control rheology of unit dose detergent pack

A detergent composition exhibiting approximate Newtonian behavior during hydration and comprising:

• A. a surfactant component comprising an alcohol ethoxy sulfate having a C8-C20 backbone that is ethoxylated with from about 1 to about 10 moles of ethylene oxide and is present in an amount of from about 5 to about 30 weight percent actives based on a total weight of said detergent composition, wherein said alcohol ethoxy sulfate is sodium laureth sulfate;
• B. water present in a total amount of from about 5 to about 10 weight percent based on a total weight of said detergent composition;
• and
• C. a tertiary amine present in an amount of about 2.5 to 5 weight percent actives based on a total weight of said detergent composition and having three arms wherein each arm comprises from about 1 to about 25 moles of ethylene oxide functionality, and
• wherein said detergent composition has a viscosity of less than about 2,000 cps and is measured using an AR2000-EX Rheometer at a shear rate of 1.08 1/s over 5 minutes at 20° C. with a geometry cone of 40 mm, 1:59:49 degree:min:sec, and a truncation gap of 52 microns when diluted with additional water at about a 2:1 weight ratio of detergent composition:water.

A method for modifying rheology of a detergent composition to be a Newtonian fluid independent of shear, said method comprising the steps of:

• providing a detergent composition comprising;
• a surfactant component comprising an alcohol ethoxy sulfate having a C8-C20 backbone that is ethoxylated with from about 1 to about 10 moles of ethylene oxide and is present in an amount of from about 10 to about 20 weight percent actives based on a total weight of the detergent composition;
• water present in a total amount of from about 5 to about 10 weight percent based on a total weight of the detergent composition;
• and
• a tertiary amine present in an amount of about 5 to about 7.5 weight percent actives based on a total weight of said detergent composition and having three arms wherein each arm comprises from about 1 to about 25 moles of ethylene oxide functionality, and
• diluting the detergent composition with additional water such that the detergent composition has a viscosity of less than about 1,000 cps at a shear rate of from about 0.41 to about 10 1/s over 5 minutes measured at 20° C. with a geometry cone of 40 mm, 1:59:49 degree:min:sec, and a truncation gap of 52 microns when diluted with additional water at about a 2:1 weight ratio of detergent composition:water.
