Title
(EN) DELIVERY SYSTEM HAVING ENCAPSULATED POROUS CARRIER LOADED WITH ADDITIVES, PARTICULARLY DETERGENT ADDITIVES SUCH AS PERFUMES
(FR) SYSTEME DE LIBERATION DOTE D'UN SUPPORT POREUX ENCAPSULE CHARGE D'ADDITIFS, NOTAMMENT D'ADDITIFS DETERGENTS TELS QUE DES PARFUMS
Abstract
(EN) The present invention relates to a delivery system for additives, which are incorporated in a variety of consumer products, including detergents and cleaning compositions, room deodorizers, insecticidal compositions, carpet cleaners and deodorizers, wherein the additive is protected from release until exposed to a wet or moist environment. Specifically, the present additive delivery system is a particle comprising a core of porous carrier material containing an additive, such as a perfume, in its pores; a first coating of a hydrophobic oil encapsulating said core; and a second coating of a water-soluble or water-dispersible, but oil-insoluble, material, such as starch or modified starch, encapsulating the hydrophobic-oil coated core. The present delivery particle can be used to deliver laundry and cleaning agents either to or through the wash cycle. A laundry additive delivery particle according to the present invention effectively delivers perfume ingredients through the wash to a fabric surface.
(FR) La présente invention concerne un système de libération d'additifs qui sont incorporés dans de nombreux produits de consommation, tels que des détergents et des compositions nettoyantes, des désodorisants, des compositions insecticides, nettoyants et désodorisants de moquette, dans lequel l'additif n'est libéré que lorsqu'il est exposé à un environnement mouillé ou humide. D'une manière plus spécifique, le système de libération d'additifs de l'invention est une particule comprenant un noyau constitué d'un matériau support poreux contenant dans ses pores un additif, tel que du parfum ; un premier revêtement en huile hydrophobe enveloppant ledit noyau ; et un second revêtement constitué d'un matériau hydrosoluble ou dispersable dans l'eau mais insoluble dans l'huile, tel que l'amidon ou l'amidon modifié, qui enveloppe le noyau enrobé d'huile hydrophobe. La particule de libération de l'invention peut s'utiliser avec des agents de nettoyage ou de lessivage lors ou pendant un cycle de lavage. Au cours du lavage, une particule de libération d'un additif de lessivage de l'invention libère efficacement sur la surface d'un tissu des ingrédients parfumés.
