Disclosed are aqueous liquid laundry detergent compositions which are in the form of an externally structured aqueous liquid matrix having dispersed therein a plurality of visibly distinct beads. Such beads are prepared so as to be in the form of a liquid core surrounded by a semi-permeable membrane formed by interaction of a cationic polymeric material with an anionic polymeric material. Such beads are stable in the aqueous liquid detergent compositions herein yet disintegrate substantially upon their introduction via the composition into agitated dilute aqueous laundering liquors.
L'invention concerne des compositions détergentes liquides de blanchisserie se présentant sous la forme d'une matrice liquide aqueuse structurée de manière externe, une pluralité de billes distinctes de manière visible étant dispersée à l'intérieur de celle-ci. Lesdites billes se présentent sous la forme d'un noyau liquide entourée par une membrane semi-perméable formée par l'interaction d'une matière polymère cationique et d'une matière polymère anionique. Lesdites billes sont stables dans les compositions détergentes liquides aqueuses et se désintègrent sensiblement lors de leur introduction par l'intermédiaire de la composition dans des lessives de blanchisserie aqueuses, diluées et agitées.
