Abstract:
1. A heavy-duty liquid detergent composition in the form of an externally-structured, aqueous liquid matrix having dispersed therein a plurality of visibly distinct beads, which composition comprises: A) from about 5% to 50% by weight of said composition of a detersive surfactant selected from anionic surfactants, nonionic surfactants, and combinations thereof; B) from about 0.1% to 30% by weight of a laundry washing adjunct selected from detersive enzymes, optical brighteners, dye transfer inhibition agents, suds suppressors, detersive soil realease polymers, other fabric care benefit agents, and combinations of said laundry washing adjuncts; C) from about 0.01% to 1% by weight of an organic external structurant selected from the group consisting of D) from about 0.01% to 5% by weight of visibly distinct beads, each of said beads comprising a cationic or anionic polymeric component and a semipermeable membrane formed by interaction of said cationic or anionic polymeric component with an anionic or cationic polymeric material of opposite charge, said membrane serving to impart osmotic permeability characteristics to said beads such that said beads maintain their structural integrity within the aqueous liquid matrix of said composition but disintegrate without leaving visible residues as a consequence of osmotic water permeability upon aqueous dilution of said composition during washing operations; and E) from about 30% to 75% by weight of water.
