A new class of compounds having fabric softening properties is formed by hydroxamic betaines having the general formula R.sup.1 (R.sup.2)(R.sup.3)N.sup.+ -- R.sup.4 -- CO -- NH -- O.sup.- in which R.sup.1, R.sup.2, R.sup.3, R.sup.4 are hydrocarbon groups having 1-25 carbon atoms with the proviso that the betaine contains not more than 45 carbon atoms, at least one carbon chain of at least 12 carbon atoms and the carbon chain of R.sup.4 between the quaternary N-atom and the CO-- group is no longer than 4 carbon atoms. The compounds, which can be used in a fabric softening rinse composition as well as in a detergent composition, remain in dispersion during the washing process, but deposit onto the fabric when the pH decreases during subsequent rinsing.
一种具有柔软织物性能的新类化合物由具有一般公式R.sup.1(R.sup.2)(R.sup.3)N.sup.+ -- R.sup.4 -- CO -- NH -- O.sup.-的羟肟甜菜碱形成,其中R.sup.1、R.sup.2、R.sup.3、R.sup.4为具有1-25个碳原子的碳氢基团,条件是甜菜碱不含超过45个碳原子,至少有一个至少含有12个碳原子的碳链,且在季铵N原子和CO-基团之间的R.sup.4的碳链不超过4个碳原子。这些化合物可用于织物柔软漂洗剂组合物以及洗涤剂组合物中,在洗涤过程中保持分散状态,但在随后的漂洗过程中pH值降低时沉积在织物上。
