Disclosed herein are amphoterically-modified ethoxylated oligoamines, their manufacture, and methods of using them.

Amphoterically-modified oligopropyleneimine ethoxylates for improved stain removal of laundry detergents

A liquid laundry composition comprising: (i) from 1 to 60 wt % of one or more surfactants selected from non-soap anionic surfactants, nonionic surfactants, and mixtures thereof; and (ii) from 0.05 to 10 wt % of an amphoterically-modified oligopropyleneimine ethoxylate having a following formula (I) wherein E is an ethoxy side chain corresponding to a formula —(RO)—R' (I) in which R units are ethylene; n has an average value from 5 to 50, preferably from 10 to 40; R′ units are each independently selected from hydrogen and SO—, wherein at least 30% of R′ units, preferably at least 50%, are SO—; Q units are each independently selected from C1-C4 alkyl, H and a free electron pair, wherein at least 50% of Q units, preferably at least 80% Y, more preferably at least 90% are C-Calkyl; and x ranges from 1 to 3.
