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过程中,纤维素材料从织物中松动并移除时,土壤和污垢被纤维素材料捕获并重新沉积到织物表面的问题。本发明的组合物包括:a)约0.01%重量的双性聚胺,其包括聚胺骨架,该骨架包括两个或更多氨基单元,其中至少一个氨基单元是季铵化的,并且至少一个氨基单元被一个或多个能够具有阴离子电荷的基团取代,进一步地,包含该阴离子基团的氨基单元的数量小于或等于季铵化骨架氨基单元的数量;b)约0.00005%重量的木聚糖酶酶;c)约0.5%至约50%重量的表面活性剂系统,包括:i)约10%至约99%重量的非离子表面活性剂;ii)约1%至约90%重量的阴离子表面活性剂;iii)可选地,选自阳离子表面活性剂,双性表面活性剂,两性表面活性剂和其混合物的洗涤性表面活性剂约1%至约50%重量的表面活性剂系统;以及d)剩余的载体和辅助成分。
