The invention relates to a polyester including two or more of the structural units (a1), one or more of the structural units (a2) and either one or two of the terminal groups (a3) Adjacent structural units (a1) are connected by the structural unit (a2). When only one terminal group (a3) is present in the polyester, the other terminal group is selected from the group consisting of OH, OCH, and GOH. Both terminal groups are linked to acyl groups derived from a dicarboxylic acid.

Soil release polyesters for use in detergent compositions

A renewably sourced soil release polyester comprising two or more structural units (a1), one or more structural units (a2) and either one or two terminal structural groups (a3) wherein

Renewably sourced soil release polyesters

What are described are compositions comprising a) one or more sugar amines of the formula (I) in which R1 and R2 are independently H, CHor 2-hydroxyethyl and/or one or more corresponding protonated sugar amines with the counterion R&#x2014;COO&#x2014; in which R is defined as R from the substances of component b) below, and b) one or more substances selected from the group consisting of fatty acids of the formula R&#x2014;COOH, fatty acid salts of the formula R&#x2014;COO-M+ and mixtures thereof, in which R is a linear or branched saturated alkyl radical having 11 to 21 carbon atoms or a linear or branched, mono- or polyunsaturated alkenyl radical having 11 to 21 carbon atoms and M+ is a counterion. The compositions described are very advantageous, for example, for production of liquid washing compositions, and of shower gels, liquid soaps or face cleansers. In addition, the sugar amines are advantageously suitable as neutralizing agents for fatty acids. 

Compositions comprising sugar amine and fatty acid

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.
