Abstract
A high-solids rinse cycle fabric softener formulation having enhanced viscosity and softening properties includes a blend of at least one imidazolinium quaternary ammonium compound, at least one dialkyl dimethyl quaternary ammonium compound and at least one solvent with the proviso that no thickening agents are utilized to achieve the enhanced viscosity properties. The formulation upon dilution increases in viscosity to a commercially successful level. The blend results in a combination of both hard and soft tallows for improved rewet and softening capabilities.
Claims35
A low-viscosity, high-solids rinse cycle fabric softener formulation comprising a blend of (a) about 1 to about 50% by weight of at least one imidazolinium quaternary ammonium compound;
- (b) about 1 to about 40% by weight of at least one dialkyl dimethyl quaternary ammonium compound;
- and (c) about 1 to about 50% by weight of at least one solvent, with the proviso that no polymeric thickening agent is present.
A method of preparing a low-viscosity, high-solids rinse cycle fabric softener formulation comprising blending about 1 to about 50% by weight of at least one imidazolinium quaternary ammonium compound;
- about 1 to about 40% by weight of at least one dialkyl dimethyl quaternary ammonium compound;
- and about 1 to about 50% by weight of at least one solvent, with the proviso that no polymeric thickening agent is present;
- said formulation capable of increased viscosity upon dilution with water.
A method of laundering comprising adding a low-viscosity, high-solids rinse cycle fabric softener formulation to an article needing laundering wherein the fabric softener formulation comprises a blend of about 1 to about 50% by weight of at least one imidazolinium quaternary ammonium compound;
- about 1 to about 40% by weight of at least one dialkyl dimethyl quaternary ammonium compound;
- and about 1 to about 50% by weight of at least one solvent, with the proviso that no polymeric thickening agent is present yet said formulation is capable of increased viscosity upon dilution with water.
