Polymer blend to stabilize highly alkaline laundry detergent

A method of washing textiles comprising:

• providing a liquid detergent composition comprising:
• a) between about 25 wt-% and about 40 wt-% alkalinity comprising alkali metal hydroxide;
• b) between about 4 wt-% and about 7 wt-% rheology modifiers comprising:
• i) a C12-C16 alkyl polyglycoside nonionic surfactant,
• ii) at least one alkali-swellable polymer (ASE) according to the following formula:
• wherein R is hydrogen or a C1 to C6 alkyl chain;
• R1 is hydrogen or a C1 to C6 alkyl chain and wherein the ratio of x:y is from 1:10 to 10:1,
• iii) at least one hydrophobically-modified alkali-swellable polymer (HASE) according to the following formula:
• wherein R is a hydrogen or C1-C6 alkyl group;
• wherein R1 is a hydrogen or C1-C6 alkyl group;
• wherein R2 is a hydrophobic alkyl group in the range from C4-C24;
• wherein R3 can be any one of a hydrogen or C1-C6 alkyl group;
• wherein the ratio of x:y is from about 1:20 to about 20:1;
• wherein the ratio of x:w is from about 1:20 to about 20:1;
• and
• wherein the ratio of x:z is from about 1:1 to about 500:1,
• 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 1.1:1 to about 4.5:1;
• c) between about 15 wt-% to about 35 wt-% ethoxylated alcohol nonionic surfactant(s);
• d) between about 15 wt-% to about 40 wt-% water;
• and
• e) optionally at least one of a chelant, sequestrant or builder;
• and
• contacting a textile with the liquid detergent composition.
