Abstract

Disclosed are highly concentrated aqueous soil release polyester formulations containing 50 to 90 percent by weight of soil release polyester and 0.1 to 40 percent by weight of a polycarboxylic acid or a polycarboxylate. Adding these highly concentrated polycarboxylic acids or polycarboxylates makes it possible to produce highly concentrated soil release polyester formulations which are stable while being provided with low viscosity.
