  • Fabric softening composition comprising a polymeric viscosity modifier
    Patent number: 8168582
    Abstract: A liquid fabric treatment composition comprising a cationic fabric softening agent and a water-soluble linear polymeric viscosity modifier represented by the formula: Z—Y—(X—Y)n—Z in which: X represents a polyether chain, each Y independently represents a linking group derived from a diisocyanate, each Z independently represents a hydrophobic group and optionally includes a spacer linked to Y, n represents an integer of at least 2, and the molecular weight of the polymer is from 2,000 to 80,000.
    Type: Grant
    Filed: May 23, 2006
    Date of Patent: May 1, 2012
    Assignee: The Sun Products Corporation
