Title
(EN) SOIL RELEASE POLYMERS AND LAUNDRY DETERGENT COMPOSITIONS CONTAINING THEM
(FR) POLYMÈRES ANTISALISSURES ET COMPOSITIONS DE DÉTERGENT À LESSIVE CONTENANT CES DERNIERS
Abstract
(EN) The invention provides a polymer providing soil release properties (also termed a "soil release polymer" or SRP) when incorporated in a laundry detergent composition, the polymer comprising a capped polyoxyalkylene end block connected to a polyester segment; the polyester segment comprising alternating -B1-A-B2- and -R- units; in which B1 and B2 are each independently selected from -OC(O)- and -C(O)O- groups; A is a 2,5-furanylene ring and R is a divalent alkylene radical. The polymer provides good compatibility, stability and cleaning performance when incorporated into a laundry detergent composition, preferably a liquid laundry detergent composition, comprising one or more detersive surfactants.
(FR) L'invention fournit un polymère fournissant des propriétés antisalissures (également appelé "polymère antisalissure" ou SRP) lorsqu'il est incorporé dans une composition de détergent à lessive, le polymère comprenant un bloc d'extrémité de polyoxyalkylène coiffé relié à un segment de polyester ; le segment de polyester comprenant des unités -B1-A-B2- et -R- alternées ; B1 et B2 étant chacun indépendamment choisis parmi des groupes -OC(O)- et -C(O)O- ; A étant un cycle 2,5-furanylène et R étant un radical alkylène divalent. Le polymère fournit une compatibilité, une stabilité et une efficacité de nettoyage satisfaisantes lorsqu'il est incorporé dans une composition de détergent à lessive, de préférence une composition de détergent à lessive liquide, comprenant un ou plusieurs tensioactifs détersifs.
