Abstract: front page image
(EN)According to the invention there is provided polymer particles comprising (i) a hydrophobically modified polymer having a lower critical solution temperature of from 5 to 60 ˚C (particularly polyvinyl alcohol backbone having one or more hydrocarbyl group substituents of from C4 to C22 carbon chain length); the polymer particle is provided as a polymer matrix comprising multiple discrete benefit agent (ii) entities embedded in the polymer matrix, wherein, the ratio of (i) to (ii) is from 1:50 to 99:1 parts by weight; also provided are surfactant compositions comprising the polymer particles, a process to make the polymer particles and to the use of the polymer particles to deliver a benefit agent to fabric and/or to a wash or rinse medium during a wash process.
(FR)L'invention porte sur des particules de polymère comprenant (i) un polymère modifié de façon hydrophobe ayant une plus basse température critique de solubilité de 5 à 60˚C (en particulier un squelette de poly(alcool vinylique) ayant un ou plusieurs substituants de type groupes hydrocarbyles ayant une longueur de chaîne carbonée en C4 à C22); la particule de polymère étant fournie sous forme d'une matrice de polymère comprenant de multiples entités discrètes, (ii) des agents bénéfique noyés dans la matrice de polymère, le rapport de (i) à (ii) étant de 1:50 à 99:1 parties en poids; l'invention porte également sur des compositions de tensioactif comprenant les particules de polymère, sur un procédé pour fabriquer les particules de polymère et sur l'utilisation des particules de polymère pour distribuer un agent bénéfique à un tissu et/ou à un milieu de lavage ou de rinçage pendant un processus de lavage.
