The present application relates to compositions comprising coated particles, and processes for making and using such particles and compositions. The covering is selected from shellac, zein, paraffins and mixtures thereof. Such particles mini-mize or eliminate certain drawbacks of benefit agents including encapsulated benefit agents. When employed in compositions, for example, 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 parti-cles allow a broad range of benefit agents to be employed.
La présente invention porte sur des compositions comprenant des particules enrobées et sur des procédés pour la fabrication et l'utilisation de telles particules et compositions. L'enrobage est choisi parmi la gomme laque, la zéine, les paraffines et des mélanges de celles-ci. De telles particules réduisent au minimum ou éliminent certains inconvénients d'agents bénéfiques y compris d'agents bénéfiques encapsulés. Lorsqu'elles sont employées dans des compositions, par exemple des compositions de nettoyage ou d'entretien de tissus, de telles particules augmentent l'efficacité de la distribution d'agents bénéfiques, ce qui permet de cette manière d'employer des quantités réduites d'agents bénéfiques. En plus de permettre de réduire la quantité d'agents bénéfiques, de telles particules permettent d'employer une large gamme d'agents bénéfiques.
