Stable solid compositions employing a water conditioning agent, including hygroscopic species or non-hygroscopic species. In particular, solid compositions combining an ionic surfactant or an amphoteric surfactant with a water conditioning agent, preferably a polyacrylate water conditioning agent, are disclosed. The ionic surfactant or amphoteric surfactant beneficially stabilize the polymer and/or chelant water conditioning agent, preferably a polyacrylate water conditioning agent, to permit formulation into a solid composition and provide stability under harsh conditions, including humid environments. Applications of using the stable solid compositions are also disclosed.

Surfactant stabilization of hygroscopic species

Solid laundry softening compositions and applications of use are disclosed. Solid laundry softening compositions combine quaternary ammonium compounds with an inorganic carrier to provide a flowable powder for solidification in a pressed or extruded solid composition. A high loading of quaternary ammonium compound in the inorganic carrier, including an inorganic salt, can be further combined with softening boosters, processing aids, surfactants, and/or additional functional ingredients to provide stable solid compositions.

Solid laundry softener composition

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.
