  • Patent number: 6727220
    Abstract: The invention provides a fabric softening composition comprising: i) at least one nonionic fabric, and ii) at least one anionic surfactant, and iii) at least one cationic polymer wherein the particles formed from i), ii) and iii) have a net negative charge and the composition comprises no more than 1% by weight non-polymeric cationic surfactant and/or cationic fabric softening compounds. The compositions give good fabric softening without decreasing absorbency, and deposit well without being detrimentally affected by anionic carry-over from the wash. Also provided is a method of depositing a nonionic fabric softening agent from a fabric softening composition, comprising emulsifying the agent with an anionic surfactant and a cationic polymer or emulsifying the agent with an anionic surfactant and then post-dosing an aqueous solution of a cationic polymer to form a particle having an overall negative charge and treating fabric therewith.
