    • The present invention solves the problem of soil and dirt becoming entrained in cellulosic material loosened and removed from fabric during washing wherein said dirt and soil is entrapped by the cellulosic material and re-deposited onto the fabric surface. The compositions of the present invention comprise: a) from about 0.01% by weight, of a zwitterionic polyamine which comprises a polyamine backbone, said backbone comprising two or more amino units wherein at least one of said amino units is quaternized and wherein at least one amino unit is substituted by one or more moieties capable of having an anionic charge wherein further the number of amino unit substitutions which comprise said anionic moiety is less than or equal to the number of quaternized backbone amino units; b) from about 0.00005% by weight, of a xyloglucanase enzyme; c) from about 0.5% to about 50% by weight, of a surfactant system comprising: i) from about 10% to about 99% by weight, of said surfactant system, of a nonionic surfactant; ii) from about 1% to about 90% by weight, of said surfactant system, of an anionic surfactant; iii) optionally, from 1% to about 50% by weight, of said surfactant system, of a detersive surfactant selected from the group consisting of cationic surfactants, zwitterionic surfactants, ampholytic surfactants, and mixtures thereof; and d) the balance carriers and adjunct ingredients.
    • 本发明解决了在洗涤期间从织物松开和去除的纤维素材料中夹带污垢和污垢的问题,其中所述污垢和污物被纤维素材料包裹并重新沉积在织物表面上。 本发明的组合物包含:a)约0.01重量%的包含多胺主链的两性离子多胺,所述骨架包含两个或更多个氨基单元,其中至少一个所述氨基单元是季铵化的,并且其中至少一个 氨基单元被一个或多个能够具有阴离子电荷的部分取代,其中进一步包含所述阴离子部分的氨基单元取代数小于或等于季铵化主链氨基单元的数量; b)约0.00005重量% 的木葡聚糖酶; c)约0.5重量%至约50重量%的表面活性剂体系,其包含:i)约10重量%至约99重量%的所述表面活性剂体系的非离子表面活性剂; ii) 约1重量%至约90重量%的所述表面活性剂体系;阴离子表面活性剂; iii)任选地,所述表面活性剂体系的1重量%至约50重量%的选自下组的去污表面活性剂: 阳离子 表面活性剂,两性离子表面活性剂,两性表面活性剂及其混合物; andd)平衡载体和辅助成分。
