Patent

CA 2439424

The present invention relates to a water-soluble and/or water-dispersible particle comprising an active ingredient uniformly dispersed, preferably an enzyme, in a matrix comprising from 20-95% by weight of the particle of polyvinyl alcohol of a molecular weight of 10-30K daltons. The present invention further relates to a process to obtain a particle, to a detergent composition comprising the particle and to the use of particle to minimise, reduce or prevent the generation of dust while providing excellent cleaning on enzyme sensitive stains and soils and on particulate stains, improved thermostability and fabric softness performance.

La présente invention concerne une particule soluble dans l'eau et/ou dispersable dans l'eau, comprenant un ingrédient actif dispersé de manière uniforme, de préférence une enzyme, dans une matrice comprenant de 20 à 95 % en poids de la particule d'alcool de polyvinyle d'un poids moléculaire de 10 à 30K daltons. La présente invention concerne également un procédé permettant d'obtenir une particule, une composition détergente comprenant la particule et l'utilisation de la particule pour minimiser, réduire ou prévenir la génération de poussière tout en garantissant un excellent nettoyage des taches et salissures sensibles à l'enzyme et des taches particulaires, ainsi qu'une thermostabilité et une efficacité d'assouplissement améliorées.
