An emulsified detergent composition is provided. The detergent composition comprises from about 0.1% to about 70%, by weight of the detergent composition, of a detersive surfactant wherein at least from about 70% to about 90%, by weight of the detersive surfactant, is a nonionic surfactant. The detergent composition also includes an electrolyte, in an amount sufficient to render the cloud point of the detergent composition to be less than about 20.degree. C., and water. The detersive surfactant and the water are in two phases in a weight ratio of about 1:10 to about 10:1 in the detergent composition. Superior cleaning and stain removal results because the emulsified detergent composition provides separation of the water and surfactant phases in a low water wash system over a broad temperature range and allows for cleaning below the cloud point of the surfactant system.

Phase separated detergent composition

Improved soil release agents for granular laundry detergents, typically used at levels as low as about 1% of a fully-formulated anionic surfactant-containing granular detergent, are reaction products of transesterifying and oligomerizing mixtures of monomers having the functions MO.sub.3 SC.sub.6 H.sub.4 C(O)--, M'O.sub.3 SC.sub.6 H.sub.3 {C(O)O--}.sub.2, --(O)CC.sub.6 H.sub.4 C(O)-- and --OCH.sub.2 CH.sub.2 O-- wherein M and M' are independently selected from lithium, potassium and sodium, more preferably sodium; said mixtures having mole ratio of MO.sub.3 SC.sub.6 H.sub.4 C(O)-- to --(O)CC.sub.6 H.sub.4 C(O)-- of from about 0.2:1 to about 1.4:1, mole ratio of MO.sub.3 SC.sub.6 H.sub.4 C(O)-- to M'O.sub.3 SC.sub.6 H.sub.3 {C(O)O--}.sub.2 of from about 0.67:1 to about 20:1 and mole ratio of MO.sub.3 SC.sub.6 H.sub.4 C(O)-- to --OCH.sub.2 CH.sub.2 O-- of from about 0.007:1 to about 0.51:1 and being substantially free from monomers of formula HOROH wherein R is propylene or higher alkyl.

Soil release agents for granular laundry detergents

Soil removal performance of granular laundry detergents containing aluminosilicate builders is improved by presence of polyaspartic acid (or its water-soluble salts) as a co-builder/soil dispersant.

Detergent compositions with builder system comprising aluminosilicates

Anionic, sulfobenzoyl end-capped esters useful as soil release agents in granular detergent compositions. The terephthalate esters contain oxyethyleneoxy and oxy-1,2-propyleneoxy units, and are substantially amorphous in form.
