Abstract

Lessive ou détergent ou composant destiné à ceux-ci, contenant au moins deux composants particulaires différents. Le premier composant particulaire comporte une poudre séchée par pulvérisation, un granulat et/ou un agglomérat, et le deuxième composant particulaire comporte un noyau et une coquille, la coquille étant composée d'au moins 30 % en poids d'un matériau correspondant au premier composant particulaire. Les composés selon l'invention permettent de réaliser une économie en agent de poudrage non réactif habituellement employé pour améliorer les propriétés d'écoulement de composants particulaires collants. Un procédé de fabrication de tels agents consiste à prendre un matériau support et à soumettre celui-ci à un composant présent sous forme coulante et/ou pulvérisable entre 15 et 40 °C de manière à former un produit intermédiaire particulaire mais non coulant, avant que le produit intermédiaire ne soit mélangé à un composant particulaire, le rapport massique du composant particulaire sur le produit intermédiaire particulaire mais non coulant étant supérieur à 1:9.
