The subject invention involves liquid fabric softener compositions for use in the rinse cycle of a laundering process, and concentrates of such compositions, the compositions and concentrates comprising: (a) from about 0.4 % to about 24 % cationic fabric softener; (b) from about 0.3 % to about 10 % hydrophobic perfume; (c) from about 0.4 % to about 20 % nonionic surfactant; (d) from 0 % to about 3 % water-soluble ionizable inorganic salt; (e) from about 60 % to about 98.5 % water; and (f) from 0 % to about 10 % other ingredients; the composition having a ratio of cationic softener to perfume of from about 1:3 to about 5:1, and a ratio of cationic softener to nonionic surfactant of from about 1:2 to about 4:1, the amount of cationic softener plus nonionic surfactant being from about 1 % to about 30 %; and the composition being a liquid aqueous phase with discrete hydrophobic particles dispersed substantially uniformly therein. The subject invention also involves processes for making such compositions and concentrates.

La présente invention se rapporte à des compositions liquides d'assouplissants conçues pour utilisation en cours de cycle de rinçage d'un processus de lavage du linge, ainsi qu'à des concentrés de telles compositions. Ces compositions et concentrés comportent (a) de 0,4 % environ à 24 % environ d'un agent assouplissant cationique, (b) de 0,3 % environ à 10 % environ d'un parfum hydrophobe, (c) de 0,4 % environ à 20 % environ d'un tensioactif non ionique, (d) de 0 % à 3 % environ d'un sel inorganique, ionisable et soluble dans l'eau, (e) de 60 % environ à 98,5 % environ d'eau et (f) de 0 % à 10 % environ d'autres ingrédients. Dans cette composition, le rapport de l'agent assouplissant cationique au parfum est compris entre 1 pour 3 environ et 5 pour 1 environ, et le rapport de l'agent assouplissant cationique au tensioactif non ionique est compris entre 1 pour 2 environ et 4 pour 1 environ, la quantité d'agent assouplissant cationique ajoutée à celle du tensioactif non ionique étant comprise entre 1 % environ et 30 % environ, et ladite composition étant une phase liquide aqueuse contenant de discrètes particules hydrophobes dispersées de manière sensiblement uniforme. La présente invention se rapporte également à des procédés de fabrication de telles compositions et de tels concentrés.
