Abstract: Low-viscosity liquid fabric softening compositions are disclosed that comprise a fabric softener active system that contains at least one ammonium fabric softener compound and less than 8% added solvent. The fabric softening compositions have a Dispersion Parameter that is less than 100, provided the fabric softening active system has a viscosity of less than 2000 cP at 80° C. and the fabric softening composition has an initial viscosity of less than 400 cP. A method of preparing the liquid fabric softening composition and a method of softening fabric articles with the liquid fabric softening composition are also disclosed.

Abstract: The presently described technology provides for methods and compositions for deactivating the allergenic protein content of surfaces by treatment with an allergenic protein deactivating compound. Preferred allergenic protein deactivating compositions of the present technology comprise: (1) cationic compounds and (2) nitrogen-containing compounds. Quaternary ammonium salts are particularly preferred allergenic protein deactivating compounds. In some embodiments, allergenic protein deactivating formulations of the present technology additionally contain antimicrobial agents to deactivate microorganisms on surfaces, in the air, or both. Additives including cyclodextrins, soluble aluminum salts, urea, alkyl trimethyl ammonium salts, polyvinyl pyrrolidone, tannic acid, immobilized tannic acid, polyphenols, enzymes, benzyl benzoate, inorganic salts, surfactants, buffers, oils, waxes, solvents, preservatives and mixtures thereof are also envisioned for use with the described technology.
