Abstract

Built laundry detergent compositions, especially granules, powders, tablets or syndet bars for domestic use, wherein the builder comprises at least in part a hybrid crystalline aluminosilicate having occluded silicate, carbonate, sulfate, phosphate, borate, nitrate, nitrite, Na2O, or mixtures thereof; and wherein the hybrid can further be chemically or physically surface-modified, combined with other builders, or processed in particular ways; and wherein the hybrid is coformulated with detergent adjuncts selected to improve the compositions, especially certain surfactants, particularly mid-chain branched types; certain bleach systems, especially those having bleach catalysts; and certain enzymes or other adjuncts.
