CA 2659918

The present invention relates to benefit agent containing delivery particles, compositions comprising said particles, and processes for making and using the aforementioned particles and compositions. When employed in compositions, for example, personal care, cleaning or fabric care compositions, such particles increase the efficiency of benefit agent delivery, there by allowing reduced amounts of benefit agents to be employed. In addition to allowing the amount of benefit agent to be reduced, such particles allow a broad range of benefit agents to be employed. The particles comprise a benefit agent composition and a wall material that at least partially surrounds said benefit agent composition, said benefit agent composition comprises at least 30 % of a first material having a CLogP of at least 2 and a boiling point of less than 280° C.

La présente invention concerne des particules de distribution contenant un agent bénéfique, des compositions comprenant ces particules, et des processus de fabrication et d'utilisation des particules et des compositions susmentionnées. Lorsqu'elles sont employées dans des compositions par exemple de soins personnels, de nettoyage ou de soins de tissus, ces particules augmentent l'efficacité de la distribution d'agent bénéfique, permettant ainsi de réduire les quantités d'agents bénéfiques à utiliser. Par ailleurs, pour permettre de réduire la quantité d'agent bénéfique à utiliser, ces particules permettent d'utiliser une grande gamme d'agents bénéfiques. Ces particules comprennent une composition d'agent bénéfique et un matériau de paroi qui entoure au moins partiellement cette composition d'agent bénéfique, cette composition comprenant au moins 30% d'un premier matériau possédant un CLogP d'au moins 2 et un point d'ébullition inférieur à 280 degrés C.
