A detergent compatible granular fabric softening composition, comprising a water soluble quaternary ammonium compound, a clay having an ion exchange capacity of at least 50 meq./100g and one or more amides, imides and urea derivatives according to four specifically defined formulae.
A preferred group of amides to be applied are those according to the formula
wherein R₁ and R₂ are the same or different and represent C₁-C₂₂ alkyl groups and wherein R₂ additionally may represent hydrogen and wherein R₃ represents hydrogen, C₁-C₂₂ alkyl, -(C₂H₄O)xH or -(C₃H₆O)xH wherein x has a value of 1 to 25, with the proviso that the sum of the carbon atoms of two radicals of R₁, R₂ and R₃ is at least 16. More preferred are N-stearylstearamide or N-oleylpalmitamide.
Additionally the invention relates to detergent-compositions comprising these softening compositions in an amount from 0.5 to 50% by weight and preferably 2-20% by weight.

水溶性季
铵化合物、一种离子交换容量至少为 50 meq./100g 的粘土和一种或多种酰胺、
亚胺和
脲衍
生物,它们符合四种特定的定义式。
优先使用的酰胺类是符合以下式子的酰胺类
其中 R₁ 和 R₂ 相同或不同,代表 C₁-C₂₂烷基,R₂ 还可以代表氢,R₃ 代表氢、C₁-C₂₂烷基、-(C₂H₄O)xH 或 -(C₃H₆O)xH 其中 x 的值为 1 至 25,但 R₁、R₂ 和 R₃ 的两个基的碳原子之和至少为 16。更优选的是 N-硬脂酰硬脂酰胺或 N-油酰棕榈酰胺。
此外,本发明还涉及包含这些软化组合物的洗涤剂组合物,其用量为 0.5%至 50%(按重量计),最好为 2%至 20%(按重量计)。
