Disclosed are thin until wet materials that are suitable for use as acquisition members for absorbent articles (e.g., diapers, catamenial products, and adult incontinence devices). Preferred materials according to the present invention are either: 1) fibrous assemblies that utilize wet strength means to stabilize the material or 2) compressed regenerated cellulosic sponges so that, when the material is saturated with an aqueous fluid, it has an expanded wet density of between about 0.04 grams/cm and about 0.4 grams/cm and an expanded capillary desorption height of less than about 25 cm and a temporary binding means that helps maintain the material at a compressed dry density between about 0.06 grams/cm and about 1.2 grams/cm until the material is exposed to an aqueous fluid. The ratio of the compressed dry density to the expanded wet density is also greater than about 1.5:1. A suitable process for making the materials and absorbent structures using the materials are also disclosed.

The present invention relates to an alkoxylated polyalkyleneimine soil dispersant having the formula:

Propoxylated/ethoxylated polyalkyleneimine dispersants

The present invention relates to an alkoxylated polyalkyleneimine soil dispersant having the formula: ##STR1## wherein R is C.sub.2 -C.sub.6 linear alkylene, C.sub.3 -C.sub.6 branched alkylene, and mixtures thereof; B is a continuation by branching; E is an alkyleneoxy unit having the formula:

The present invention relates to laundry detergent compositions which comprise an alkoxylated polyalkyleneimine soil dispersant having the formula: ##STR1## wherein R is C.sub.2 -C.sub.6 linear alkylene, C.sub.3 -C.sub.6 branched alkylene, and mixtures thereof; B is a continuation by branching; E is an alkyleneoxy unit having the formula:

Laundry compositions comprising alkoxylated polyalkyleneimine dispersants

The present invention relates to laundry detergent compositions which comprise bleach compatible hydrophobic soil dispersants. The dispersants are polyalkyleneimines having a backbone molecular weight of from about 2000 to about 5000 daltons and having most of the N--H unit hydrogens, preferably all N--H unit hydrogens substituted with from about 20 to about 50, alkyleneoxy units.

Bleach compatible alkoxylated polyalkyleneimines

Soil release agents which comprise: an ester backbone comprising (1) units selected from dihydroxy or polyhydroxy sulfonate (e.g., a sulfoethyl ether of glycerin), a unit which is at least trifunctional whereby ester linkages are formed resulting in a branched oligomer backbone (e.g., glycerol), or mixtures thereof, (2) terephthaloyl unit, and (3) oxyalkyleneoxy unit; and one or more capping units (preferably anionic).

Ester oligomers suitable as soil release agents in detergent compositions

High yields of 2,2'-oxodisuccinate are secured by reacting maleate and malate in aqueous alkaline media containing mixtures of particular divalent (e.g., Ca.sup.2+) and solubilizing monovalent (e.g., Na.sup.+) cations. In a preferred embodiment, the process has both an elevated temperature primary reaction step and one or more low temperature maturation steps. Yields of 2,2'-oxodisuccinate are increased and formation of fumarate byproduct is minimized.
