Abstract
Disclosed is a detergent composition containing one or more anionic surfactants and one or more soil release agents characterized by the presence of an anionic surfactant-interactive nonionic hydrophile and/or an anionic surfactant-interactive hydrophobic moiety, or both, and a soil release agent-enhancing amount of a polyhydroxy fatty acid amide surfactant of the formula: ##STR1## wherein R.sup.1 is H, C.sub.1 -C.sub.4 hydrocarbyl, 2-hydroxy ethyl, 2-hydroxy propyl, or a mixture thereof, R.sub.2 is C.sub.5 -C.sub.31 hydrocarbyl, and Z is a polyhydroxylhydrocarbyl having a linear hydrocarbyl chain with at least 3 hydroxyls directly connected to the chain, or an alkoxylated derivative thereof.
Claims1
A detergent composition, comprising at least about 4% by weight of an anionic surfactant, from about 3% to about 50% by weight of a polyhydroxy fatty acid amide surfactant of the formula:
- ##STR18## wherein R.sup.1 is H, C.sub.1 -C.sub.4 hydrocarbyl, 2-hydroxy ethyl, 2 hydroxy propyl, or a mixture thereof, R.sup.2 is C.sub.5 -C.sub.31 hydrocarbyl, and Z is a polyhydroxyhydrocarbyl having a linear hydrocarbyl chain with at least 3 hydroxyls directly connected to said chain, or an alkoxylated derivative thereof;
- from about 0.1% to about 10% by weight of a member selected from the group consisting of:
- anionic oligomeric esters or anionic polyesters comprising sulfophthaloyl, sulfoiso-phthaloyl or sulfobenzoyl groups acting as a soil release agent;
- and
- the balance of the composition comprising additional detersive ingredients and carriers.
