    摘要： Detergent formulation for washing laundry characterized in that it comprises: from about 10 to 80% of its weight of at least one hydrated zeolite (z) of formula xNa.sub.2 O.yAl.sub.2 O.sub.3.zSiO.sub.2.wH.sub.2 O in which, if y=1, x is from about 0.7 to 1.1, z is from about 1.3 to 3.3 and w is from about 10 to 264 from about 0.005 to 5%, of its weight of a least one polyalkylene terephthalate-polyoxyalkylenebisurethane (PET-UPOEU) copolymeric nonionic or anionic anti-soiling agent, said copolymer being obtained by reaction of a polyalkylene terephthalate (PET) and a polyoxyalkylnebisurethane (UPOEU), the molar ratio of the NCO functions to all of the OH functions or OH function equivalents being from about 0.5 to 1, from about 3 to 40%, of its weight of a least one saturated C.sub.5 -C.sub.24, aliphatic or hydroxyaliphatic alkyl sulphate anionic surfactant (FAS) optionally condensed with approximately 0.5 to 30 mol of ethylene oxide and/or propylene oxide, optionally, up to 15% of its weight of a nonionic surfactant, it not being possible for more than 5% by weight of the said detergent formulation to consist of an alkylbenzenesulphonate. It has been observed that this PET-UPOEU type of anti-soiling agent, present in low amount in detergent compositions based on zeolite and aliphatic alkyl sulphate, has advantageous anti-soiling properties.
