    • 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.
    • 用于洗涤衣物的洗涤剂制剂,其特征在于其包含:其重量的约10至80%的至少一种式xNa2O.yAl2O3.zSiO2.wH2O的水合沸石(z),其中如果y = 1,x为约 0.7至1.1,z为约1.3至3.3,w为约0.005至5重量%的至少一种聚对苯二甲酸亚烷基酯 - 聚氧化亚烷基双氨酯(PET-UPOEU)共聚物非离子或阴离子防污剂 所述共聚物是通过聚对苯二甲酸亚烷基酯(PET)和聚氧化亚烷基双氨酯(UPOEU)的反应获得的,NCO官能团与所有OH官能团或OH官能当量的摩尔比为约0.5至1,约3至40 至少一种饱和C 5 -C 24脂族或羟基脂肪族烷基硫酸盐阴离子表面活性剂(FAS)的重量%,任选地与约0.5至30摩尔环氧乙烷和/或环氧丙烷缩合,任选地至多15重量% 的非离子表面活性剂 超过5重量%的所述洗涤剂配方可能由烷基苯磺酸盐组成。 已经观察到,基于沸石和脂族烷基硫酸盐的洗涤剂组合物中存在的PET-UPOEU型防污剂具有有利的抗污染性能。
