  • Patent number: 7078374
    Abstract: A method of preparing an aqueous dispersion of a fabric conditioning composition comprises mixing 7.5 to 60% by weight of a cationic fabric softening compound, the compound having one or more hydrocarbyl chains formed from parent fatty acyl compounds or fatty acids having an iodine value of from 0 to 20 with 0.01%–1.5% by weight of a nonionic surfactant viscosity modifier and up to 1.4% by weight of a fatty alcohol, the combination of (b) and (c) being no more than 1.5% by weight, based on the total weight of the composition, the aqueous dispersion being subjected to high-shear below the phase transition temperature of compound (a) for a time sufficient to provide a composition having a viscosity of from 10 to 250 mPa·s measured at 20 s?1 using a Haake NV1 Rotoviscometer at 20° C.
    Type: Grant
    Filed: August 24, 2001
    Date of Patent: July 18, 2006
    Assignee: Unilever Home & Personal Care USA division of Conopco, Inc.
    Inventors: Jane Howard, Kevin Anthony Ormandy, John Stuart Parsons
  • Patent number: 7056881
    Abstract: An aqueous fabric conditioning composition comprises (a) 7.5 to 60% by weight of a cationic fabric softening compound of a quaternary ammonium softening compound, the compound having one or more hydrocarbyl chains formed from parent fatty acyl compounds or fatty acids having an iodine value of between 0 and 20, (b) 0.01%–1.5% by weight of a nonionic surfactant viscosity modifier and (c) optionally up to 1.4% by weight of a fatty alcohol wherein the combination of (b) and (c) is no more than 1.5% by weight of the composition and the composition comprises particles having a mean diameter of from 0.3 to 7 microns, measured using a Malvern Mastersizer.
