Abstract
A low-solvent fabric-modifier sheet for in-dryer use is provided which comprises water, a polyalkylene glycol, and an amount of an organic gelling agent effective to dimensionally stabilize the sheet, having uniformly distributed in said sheet an effective amount of at least one zwitterionic fabric-softening agent.
Claims15
A fabric-softener comprising a dimensionally stable gelled sheet comprising about 40-70% water, about 5-30% of a water-miscible solvent selected from the group consisting of a liquid polyalkylene glycol, a liquid monomethoxypolyalkylene glycol and mixtures thereof;
- and an amount of a fatty acid salt gelling agent effective to form a dimensionally gelled stable sheet, having uniformly distributed therein an effective amount of a zwitterionic fabric softening agent;
- wherein said sheet leaves an insignificant residue in a rotary hot air dryer following a laundry drying cycle.
The fabric softener comprising a gelled sheet formed by a process comprising:
- (a) forming a uniform liquid dispersion of an effective amount of zwitterionic fabric-softening agent, and about 5-20% of a fatty acid salt gelling agent in about 45-60% water and about 15-25% of a liquid, water-miscible polyethylene glycol;
- and
- (b) forming the dispersion into a dimensionally stable gelled sheet;
- wherein said sheet leaves an insignificant residue in a rotary hot air dryer following a laundry drying cycle.
