Abstract
Liquid detergent compositions with polymer blends to provide a stable aqueous use solution of a highly alkaline detergent composition are provided. The liquid detergent composition include concentrates and use solutions with blends of alkali-swellable polymers (ASE) and hydrophobically-modified alkali-swellable polymers (HASE). Methods for washing textiles using the liquid detergent compositions are also provided.

A method of washing textiles comprising:
- providing a liquid detergent composition comprising:
- between about 1 wt-% and about 50 wt-% alkalinity;
- between about 1 wt-% and about 10 wt-% rheology modifiers comprising at least one alkali-swellable polymer (ASE) and at least one hydrophobically-modified alkali-swellable polymer (HASE), wherein the ASE rheology modifier has a molecular weight between about 20,000 to about 300,000 g/mol, and wherein the HASE rheology modifier has a molecular weight between about 50,000 to about 500,000 g/mol, and wherein the ratio of the HASE rheology modifier to the ASE rheology modifier is from about 0.5:1 to about 10:1;
- between about 1 wt-% to about 50 wt-% nonionic surfactant(s);
- between about 10 wt-% to about 80 wt-% water;
- and
- optionally at least one of chelant/sequestrant/builder;
- and
- contacting a textile with the liquid detergent composition.
