Stable surfactant compositions for suspending components
View Patent ↗A free-flowing surfactant composition comprising at least one anionic surface-active agent, an alkanolamide, an electrolyte, and water is described. In particular, the composition is a surfactant composition that has free-flowing non-Newtonian shear thinning properties and the ability to suspend components and is stable under at least one freeze/thaw cycle.
1. A composition comprising:
(a) about 5% to about 30% by weight of sodium trideceth sulfate;
(b) about 1% to about 20% by weight of at least one material comprising lauroamphoacetate or cocoamidopropyl betaine;
(c) about 0.1% to about 10% by weight of cocomonoethanolamide;
(d) water;
(e) about 0.1% to about 3% by weight of guar hydroxypropyl trimonium chloride;
(f) about 0% to about 35% by weight of an oil phase; and
(g) salt.
2. The composition of claim 1 , wherein in (b) the material comprises lauroamphoacetate.
3. The composition of claim 1 , wherein the pH of the composition is about 4.0 to about 6.5.
4. The composition of claim 1 further comprising about 0.1% to about 3.0% by weight of a nonionic guar gum.
5. The composition of claim 1 wherein the oil phase comprises an oil comprising a vegetable, mineral, or silicone oil.
6. The composition of claim 1 , wherein said composition comprises a total salt content of about 1% to about 6% by weight.
7. The composition of 1 wherein the salt is NaCl.
8. The composition of 5 wherein the vegetable oil comprises sunflower oil or soy bean oil.
9. The composition of claim 1 , wherein said composition comprises about 5% to about 20% by weight of sodium trideceth sulfate.
10. The composition of claim 1 , wherein said composition comprises about 1% to about 3% by weight of at least one material comprising lauroamphoacetate or cocoamidopropyl betaine.
11. The composition of claim 1 , wherein said composition comprises about 0.1% to about 5% by weight of cocomonoethanolamide.
12. The composition of claim 6 , wherein said composition comprises a total salt content of 3% by weight.
