Abstract
Detergent compositions and, more specifically, low pH detergent compositions comprising nonionic surfactants that are suitable for washing of clothes, and methods of making and using the same.
Claims20
A liquid laundry detergent composition comprising:
- from about 2% to about 20% by weight of the composition of a surfactant system,
- wherein the surfactant system comprises
- a first nonionic surfactant (A), wherein A has a HLB less than about 10,
- a second nonionic surfactant (B), wherein B has a HLB greater than about 10,
- wherein the weight ratio of A:B is from about 1:100 to about 40:100;
- and
- anionic surfactant;
- wherein the composition has a neat pH of from about 1.5 to about 6.9;
- and wherein the composition has a viscosity of from about 200 cps to about 3000 cps measured at 20 s−1 at 21.1° C.
6 more elements
A composition according to claim 3, wherein the first nonionic surfactant (A) is selected from the group consisting of:
- C12,13 EO2;
- C12,13 EO3;
- and mixtures thereof.
A composition according to claim 5, wherein the second nonionic surfactant (B) is selected from the group consisting of:
- C11,16 EO7;
- C14,15 EO7;
- C12,14 EO7;
- C12,14 EO9;
- and mixtures thereof.
2 more elements
A liquid laundry detergent composition comprising:
- from about 2% to about 20% by weight of the composition of a surfactant system,
- wherein the surfactant system comprises
- a first nonionic surfactant (A), wherein A has an HLB less than about 10,
- a second nonionic surfactant (B), wherein B has an HLB greater than about 10,
- wherein the weight ratio of A:B is from about 1:100 to about 40:100;
- and
- anionic surfactant;
- from about 5% to about 15%, by weight of the composition, of organic acid, wherein the organic acid comprises no more than 6 carbon atoms;
- from about 60% to about 90% water;
- wherein the composition has a neat pH of from about 2 to about 4;
- and wherein the composition has a viscosity of from about 200 cps to about 1200 cps measured at 20 s−1 at 21.1° C.
