Highly concentrated, aqueous oligoester and polyester formulations

摘要

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.
