Abstract
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.
Claims18
A method for treating fabric in a wash wheel, the method comprising:
- (a) providing a solid laundry softening composition comprising:
- at least about 15 wt-% of a quaternary ammonium compound having the formula:
- wherein R1 and R2 represent the same or different hydrocarbyl groups having from 8 to 24 carbon atoms, R3 and R4 represent the same or different hydrocarbyl groups containing 1 to about 4 carbon atoms, and X is an anion;
- and
- from about 50 wt-% to about 80 wt-% of an inorganic salt carrier comprising a magnesium cation,
- wherein the solid laundry softening composition is a stable solid composition formed from a flowable powder and does not contain organic salt carrier;
- (b) contacting the solid laundry softening composition with water to form an aqueous suspension;
- and
- (c) dispensing the aqueous suspension to a wash wheel, where it contacts the fabric to be treated.
