The invention relates to liquid laundry detergent compositions comprising a) one or more polyesters comprising two or more of the repeating structural unit (a1), one or more of the repeating structural unit (a2) and either one or two of the terminal group (a3), wherein Gis one or more of (OCH) with n being a number of from 2 to 10, Ris a Calkyl, p is based on a molar average, a number of from 0 to 60, q is based on a molar average, a number of from 0 to 50, whereby the (OCH)&#x2014; and (OCH)&#x2014; groups of the terminal group (a3) may be arranged blockwise, alternating, periodically and/or statistically and wherein the connections of the groups (OCH)&#x2014; and (OCH)&#x2014; to R&#x2014; and &#x2014;NH are free to vary, adjacent structural units (a1) are connected by the structural unit (a2), in the case that only one terminal group (a3) is present in the polymer, the other terminal group is selected from the group consisting of OH, OCH, and GOH, and both terminal groups may only be linked to the structural unit (a1), and b) one or more surfactants. The one or more polyesters of component a) possess advantageous stability in alkaline environments, beneficial solubility and advantageously are clearly soluble in alkaline compositions such as liquid laundry detergent compositions and also possess advantageous soil release properties on fatty and oily stains.
