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 a non-alkoxylated esteramine.
Claims19
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. from about 0.1% to about 10% by weight of the composition of a non-alkoxylated esteramine, wherein the non-alkoxylated esteramine has the formula (I), or a partially or fully protonated structure thereof:
- R1—O(O)C—(CH2)a—N—(R2)2 (I)
- wherein:
- R1 is a branched or unbranched C4-C10 alkyl;
- each R2 is independently selected from branched or unbranched C1-C5 alkyl;
- and
- index a is from 1 to 6.
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. a non-alkoxylated esteramine, wherein the non-alkoxylated esteramine has the formula (II), or a partially or fully protonated structure thereof:
- R1—O(O)C—(CH2)a—N—(R2)2 (II)
- wherein:
- R1 is a branched or unbranched C3-C16 alkyl;
- each R2 is independently selected from branched or unbranched C1-C5 alkyl;
- and
- index a is from 1 to 6.
