ABSTRACT:
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.
