CA 2245572

The invention provides a process for producing a particulate laundry additive composition. More particularly, the process produces a particulate laundry additive for perfume delivery in laundry detergent compositions, especially those in the form of granules or agglomerates. The process includes mixing a porous carrier material, typically containing perfume, and an encapsulating material, typically a carbohydrate material, to form agglomerates or an extrudate which is then sized into particles for incorporation into a detergent product. The process may be employed to produce particulate additive compositions which may be used in fabric softening and diswhashing as well as laundry detergent compositions.

L'invention concerne un procédé pour produire un additif particulaire pour un détergent à lessive. Plus particulièrement, le procédé permet de produire un additif particulaire (surtout sous forme de granulés ou d'agglomérats) pour un détergent à lessive, émettant un parfum. Le procédé consiste à mélanger un matériau de support poreux, contenant typiquement un parfum, et un matériau d'encapsulation, typiquement un hydrate de carbone et ensuite à former des agglomérats ou un extrudat qui est ensuite réduit en particule pouvant être incorporées dans un détergent. Le procédé peut servir à produire des additifs particulaires qui peuvent être utilisés non seulement dans des compositions de détergents à lessive, mais également dans des compositions d'adoucissants pour textiles et dans des compositions pour laver la vaisselle.
