Abstract:
A powder detergent composition consisting ofa) anionic surfactants, non-ionic surfactants, amphoteric surfactants, or mixtures thereof; b) builder; c) from 0.1 to 75 weight percent, based on the total weight of the powder detergent composition, of a polymer having a hdrophilic backbone and at least one hydrophobic moiety, wherein said hydrophilic backbone is prepared from one monomer selected from the group consisting of unsaturated C1-C6 acids, and esters, wherein said hydrophilic backbone is optionally substituted with one or more amino, amine, amide, sulfonate, sulfate, phosphonate, hydroxy, carboxyl or oxide groups; wherein said hydrophobic moiety is prepared from a monomer selected from the group consisting of siloxanes, saturated or unsaturated alkyl and hydrophobic alkoxy groups, aryl and aryl-alkyl groups, and combinations thereof, provided that said polymer does not include partially esterified copolymers of maleic anhydride or substituted maleic anhydride; and d) one or more additives selected from the group consisting of enzymes, bleaching agents, bleach activators, dye transfer inhibitors, anticorrosion materials, antistatic agents, optical brighteners, perfumes, fragrances, dyes, fillers, chelating agents, fabric whiteners, brighteners, sudsing control agents, buffering agents, soil release agents, and fabric softening agents.
