Abstract
The need for a liquid detergent composition for washing dishes which provides effective removal of both crystalline and polymerised grease, while requiring less time and effort to clean and rinse the dishes, is met when the composition is formulated with a surfactant system having an anionic surfactant, a co-surfactant, and an esteramine.
Claims20
A liquid hand dishwashing cleaning composition comprising from about 5% to about 50% by weight of the total composition of a surfactant system wherein the surfactant system comprises:
- a. an anionic surfactant
- b. a co-surfactant selected from the group consisting of an amphoteric surfactant, a zwitterionic surfactant, and mixtures thereof;
- and
- c. an esteramine, wherein the esteramine has the formula (I):
- [R1C(O)O(CH2)c]aN[(R2)b(AO)dH](3−a) (I)
- wherein:
- each R1 is independently a branched C8 alkyl;
- each R2 is independently a C1 to C5 alkyl;
- the index a is either about 1 or about 2;
- the index b is independently selected from 0 to about 3;
- the index c is independently selected from about 1 to about 5;
- each AO is independently selected from an ethoxy-, propoxy-, butoxy-, or a mixture thereof;
- and
- the index d is independently selected from 0 to about 3.
A method for removing grease from dishware using a liquid detergent composition, wherein the liquid detergent composition comprises:
- a. an anionic surfactant;
- b. a co-surfactant selected from the group consisting of an amphoteric surfactant, a zwitterionic surfactant, and mixtures thereof;
- and
- c. an esteramine, wherein the esteramine has the formula (II):
- [R1C(O)O(CH2)c]aN[(R2)b(AO)dH](3−a) (II)
- wherein:
- each R1 is independently a C3 to C16 alkyl;
- each R2 is independently a C1 to C5 alkyl;
- the index a is either 1 or 2;
- the index b is independently selected from about 0 to about 3;
- the index c is independently selected from about 1 to about 5;
- each AO is independently selected from an ethoxy-, propoxy-, butoxy-, or a mixture thereof;
- and
- the index d is independently selected from about 0 to about 3.
