The present invention relates to a multi-phase detergent composition of compressed particulate matter, wherein the average particle density of one phase differs from the average particle density of at least one other phase by at least 25g/l.The phases of the compositions of the present invention are easy to separate and avoid excessive contamination which would cause problems for reblend operations.The present invention also relates to a method of separating the phases of a multi-phase detergent compositions of compressed particulate matter, wherein the average particle density of one phase differs from the average particle density of at least one other phase by at least 25g/l, said method comprising the steps:(a) breaking up the compressed composition into particles, and(b) separating phases on the basis of their density.
L'invention concerne une composition détergente à plusieurs phases sous forme de matière particulaire comprimée, dans laquelle la densité moyenne de particule d'une phase diffère de la densité moyenne de particule d'au moins une autre phase de 25 g/l au moins. Les phases des compositions de l'invention sont faciles à séparer et permettent d'éviter une contamination excessive qui causerait des problèmes lors d'opérations de refaçonnage. L'invention concerne aussi un procédé de séparation des phases de compositions détergentes à plusieurs phases constituées de matières particulaires, dans lesquelles la densité la densité moyenne de particule d'une phase diffère de la densité moyenne de particule d'au moins une autre phase de 25 g/l au moins, ce procédé consistant (a) à réduire sous forme de particules la composition comprimée, et (b) à séparer les phases sur la base de leur densité.
