Solid laundry fabric softening compositions for laundry applications of use are disclosed. In particular, solid laundry fabric softening compositions combining quaternary dialkyl actives with low iodine values and silicone provide softness without causing any significant yellowing or loss of water absorption or wicking to the treated linen. The solid laundry fabric softening compositions can be provided as a multi-use block having uniform dispensing rates and without block sloughing. Beneficially, the combination of processing aids for solidification comprising one or more of (A) polyethylene glycol and an acidulant, (B) a surfactant and an acidulant, or (C) polyethylene glycol, a surfactant and an acidulant, are combined with the quaternary ammonium compounds and silicone to provide the stable solid composition.
本发明公开了用于洗衣用途的固体洗衣织物柔软组合物。特别是,固体衣物织物柔软剂组合物结合了低碘值的季烷基二烷基活性物质和硅氧烷,在提供柔软度的同时,不会使处理过的亚麻布明显变黄或失去吸水性或吸水性。固体洗衣织物柔顺剂组合物可以多用途块状形式提供,具有均匀的分配率,且不会出现块状剥落。有益的是,由以下一种或多种组成的固化加工助剂组合与季铵盐化合物和有机硅结合,可提供稳定的固体组合物:(A) 聚乙二醇和酸化剂;(B) 表面活性剂和酸化剂;或 (C) 聚乙二醇、表面活性剂和酸化剂。
