ESTER OLIGOMERS SUITABLE AS SOIL RELEASE AGENTS IN DETERGENT COMPOSITIONS

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...

Beschreibung
Zusammenfassung:	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) therephthaloyl unit, and (3) oxyalkyleneoxy unit; and one or more capping units (preferably anionic). Agents de lavage comprenant: un squelette ester formé (1) d'unités choisies dans un dihydroxy ou un polyhydroxy sulfonate (par exemple un éther sulfoéthyle de glycérine), une unité au moins trifonctionnelle par laquelle des liaisons ester sont formées pour donner un squelette oligomère ramifié (par exemple du glycérol) ou des mélanges de ces éléments, (2) une unité téréphtaloyle et (3) une unité oxylalkylèneoxy; et une ou plusieurs unités de coiffage (de préférence anionique).
