CA 2689552

A cleansing or a surface-conditioning composition comprising a mixture of (i) and (ii) in water: i) a surfactant selected from the group consisting of anionic, non- ionic, zwitterionic, cationic, and mixtures thereof; and ii) a hydrophobic benefit agent in a particulate form having a mean particle size in the range of i - 1,000 micron, and a specific gravity of > l, not encapsulated within a film or a capsule-like enclosure, the particulate hydrophobic benefit agent comprising: a) a physically- modified form of the hydrophobic benefit agent; and b) a deposition-aid material bonded to the surface of the physically-modified benefit agent, wherein the bonding between the benefit agent and the deposition-aid material is achieved prior to addition to i), wherein said deposition-aid material is not a surfactant having a weight average molecular weight of less than 5,000 Dalton.

L'invention concerne une composition de nettoyage ou de conditionnement de surface comprenant un mélange de (i) et (ii) dans l'eau : i) un tensioactif choisi dans l'ensemble constitué de tensioactifs anioniques, non ioniques, zwittérioniques, cationiques et de leurs mélanges; et ii) un agent utile hydrophobe sous une forme particulaire dont la taille moyenne de particules est comprise dans l'intervalle de 1 à 1000 microns, et de densité > 1, non encapsulé dans un film ou une enveloppe de type capsule. L'agent utile hydrophobe particulaire comprend: a) une forme physiquement modifiée de l'agent utile hydrophobe; et b) un matériau d'aide au dépôt, lié à la surface de l'agent utile physiquement modifié, la liaison entre l'agent utile et le matériau d'aide au dépôt étant effectuée avant l'addition à i), ledit matériau d'aide au dépôt n'étant pas un tensioactif ayant un poids moléculaire moyen en poids inférieur à 5000 Daltons.
