Abstract
Liquid detergent compositions can be stably structured using amides of an aliphatic polyamine with two, three or four molecules of fully saturated hydroxyl alkyl acids, even in the presence of hydrolysing detergent ingredients such as lipase enzyme.
Claims15
A liquid detergent composition comprising:
- a) an amide that is a reaction product of an aliphatic polyamine with two, three, or four molecules,
- wherein the two, three, or four molecules are selected from fully saturated hydroxyl alkyl acids that comprise an alkyl group having from about 16 to about 20 carbons, and
- wherein the polyamine comprises at least one primary amino group for each saturated hydroxyl alkyl acid;
- and
- b) a surfactant;
- wherein the detergent composition has a pH of greater than about 6.
A unit dose article comprising one or more compartments, the one or more compartments formed by water-soluble film which fully encloses one or more inner volumes,
- wherein the unit dose article comprises a first liquid detergent composition, the first liquid detergent composition comprising a surfactant, and
- wherein the unit dose article further comprises an amide which is a reaction product of an aliphatic polyamine with two, three or four molecules selected from fully saturated hydroxyl alkyl acids which comprise an alkyl group having from about 16 to about 20 carbons, wherein the polyamine comprises at least one primary amino group for each saturated hydroxyl alkyl acid.
A process for making a detergent composition, comprising the steps of:
- a. providing a structuring or thickening premix comprising:
- i. from about 2 to about 10% by weight of an amide which is a reaction product of an aliphatic polyamine with two or three molecules selected from fully saturated hydroxyl alkyl acids which comprise an alkyl group having from about 16 to about 20 carbons, wherein the polyamine comprises at least one primary amino group for each saturated hydroxyl alkyl acid;
- ii. from about 8 to about 24% by weight of a surfactant;
- iii. an alkali agent;
- and
- iv. solvent;
- wherein the structuring or thickening premix has a pH of greater than about 6;
- and
- b. adding the structuring or thickening premix to a composition comprising a solvent and a surfactant.
