  • FLUID FABRIC ENHANCER COMPOSITIONS
    Publication number: 20160348040
    Abstract: Fluid fabric enhancer compositions comprising microcapsules having a cationic, nonionic and/or anionic coating, a formaldehyde source that can comprise components of said microcapsules and a formaldehyde scavenger, as well as processes for making and using such fluid fabric enhancer compositions. Such fluid fabric enhancer compositions contain a formaldehyde scavenging system that provides more consistent formaldehyde scavenging over time.

  • Cationic polymer stabilized microcapsule composition
    Patent number: 8765659
    Abstract: The present invention relates to the use of a cationic polymer to provide stability to microcapsules in a composition, wherein the microcapsule comprises a shell encapsulating materials having an average C log P of at least 2.5 and more than 60% by weight of the encapsulated materials have a C log P of at least 3.3. The cationic polymer is derived from the polymerization of 5 to 100 mole percent of a cationic vinyl addition monomer, 0 to 95 percent acrylamide, and 5 to 500 ppm of a tetrafunctional vinyl addition monomer cross-linking agent. The cationic polymer and encapsulated material may be used, for example, in a fabric softener composition.

  • ENCAPSULATES
    Publication number: 20110152147
    Abstract: Encapsulates, compositions, packaged products and displays comprising such encapsulates, and processes for making and using such encapsulates, compositions, packaged products and displays. Such compositions have improved deposition and retention properties that may impart improved benefit characteristics to a composition and/or situs.
