  • Patent number: 10011807
    Abstract: A fabric conditioning active composition comprising an esterquat mixture of quaternized mono-, di-, and tri-esters of alkanolamine in which the tri-esterquat content of the quaternized esterquat mixture is greater than 25% by weight of the esterquat mixture, and the combined di-esterquat and tri-esterquat content in the esterquat mixture is greater than 78% by weight of the esterquat mixture. Additionally, the free fatty acid content of the composition is greater than 1% by weight based on the weight of the esterquat mixture. The fabric conditioning active composition provides high viscosity when dispersed into water at low concentrations of 0.5% to 12%, without the need for additional polymeric thickeners or other thickening additives.

  • Patent number: 9453185
    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.
