1. 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 and/or R1 is a hydrogen, CH3 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 and/or builder.
