Abstract
Adjuvant surfactant compositions for beneficially modifying the properties, particularly rheological properties, of surfactant systems are provided. The surfactant compositions, which include at least one primary surfactant and can be substantially free of monoethanolamines, diethanolamines, and diethanolamides include alkoxylated hydroxyalkyl isostearamide which is substantially a liquid at room temperature. The isostearamide composition may also include a second surfactant. Methods of preparation and uses are also disclosed.
Claims46
A surfactant system comprising:
- a) a primary surfactant composition;
- and
- b) an adjuvant composition comprising (C2-C4)alkoxylated mono(C2-C3)alkanol isostearamide, wherein the adjuvant composition is substantially a liquid at room temperature and modifies the rheological properties of the surfactant system.
An adjuvant composition for modifying the rheological properties of a surfactant system, wherein the composition is substantially liquid at room temperature and comprises a surfactant adjuvant comprising (C2-C4) alkoxylated hydroxy (C2-C3) alkyl isostearamide and a second surfactant different than the adjuvant.
A method of thickening a surfactant system comprising at least one primary surfactant, the method comprising the step of adding to the surfactant system an adjuvant composition comprising (C2-C4) alkoxylated hydroxyethyl isostearamide which is substantially a liquid at room temperature.
A method of thickening a surfactant system comprising at least one primary surfactant, the method comprising the step of adding to the surfactant system a composition comprising polypropylene glycol hydroxyethyl isostearamide and a second surfactant.
A surfactant system free of any added monoethanolamines, diethanolamines, and diethanoamides comprising the reaction product of
- a) a primary surfactant composition;
- and
- b) an adjuvant composition comprising alkoxylated hydroxyalkyl isostearamide, which is substantially liquid at room temperature and modifies the rheological properties of said surfactant system.
A cleansing composition comprising:
- a) a detersive composition selected from the group consisting of sodium lauryl sulfate, sodium lureth sulfate, ammonium lauryl sulfate, ammonium lauryl ether sulfate, sodium 2-(C14-C16) alkene sulfonate, sodium 3-hydroxy (C14-C16) alkene sulfonate, sodium 4-hydroxy (C14-C16) alkene sulfonate, cocoamidopropyl betaine, and combinations thereof;
- and
- b) an adjuvant composition to modify the rheological properties that is free of any added monoethanolamines, diethanolamines and is substantially a liquid at room temperature comprising polypropylene glycol hydroxyethyl isostearamide and a second surfactant different than the isostearamide selected from the group consisting of polypropylene glycol hydroxyethyl caprylamide, polypropylene glycol hydroxyethyl cocamide and combinations thereof.
A surfactant system free of any added monoethanolamines, diethanolamines and diethanaolamides comprising:
- a) a primary surfactant composition;
- and
- b) an adjuvant composition comprising polypropylene glycol hydroxyethyl isostearamide, wherein the adjuvant composition is substantially a liquid at room temperature and modifies the rheological properties of said surfactant system.
A cleaning composition comprising PPGn hydroxyethyl isostearamide and a (C14-C16) alkene sulfonate wherein n is from 1 to 2.
