Peggy Sands has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10092485
    Abstract: The present invention relates to benefit agent containing delivery particles, compositions comprising said particles, and processes for making and using the aforementioned particles and compositions. When employed in compositions, for example, cleaning or fabric care compositions, such particles increase the efficiency of benefit agent delivery, thereby allowing reduced amounts of benefit agents to be employed. In addition to allowing the amount of benefit agent to be reduced, such particles allow a broad range of benefit agents to be employed.

  • Publication number: 20070021533
    Abstract: The invention teaches an encapsulated curable adhesive composition especially adapted for use as a structural adhesive. The adhesive composition enables formation of a thin layer reactive composition of microcapsules and a two-part curative. The adhesive composition comprises a first population of microcapsules encasing a monomer and a first-part curative comprising an initiator. The adhesive composition further comprises a second-part curative. The second-part curative comprises an activator and a catalyst. At least the activator of the second-part curative is preferably encapsulated in a second population of microcapsules. The catalyst and the second population of microcapsules can be dispersed in a binder material, along with the first population of microcapsules. The first population of microcapsules contain encapsulated within the core a monomer having a Tg 35° C. or less and the first-part curative. The first population microcapsules contain encapsulated within the core a monomer having a Tg 35° C.

  • Publication number: 20060263519
    Abstract: A novel method of forming water in oil microcapsules is disclosed. According to the invention microcapsules are obtained by steps comprising dispersing an oil soluble amine modified polyfunctional polyvinyl monomer and an oil soluble bi- or polyfunctional vinyl monomer along with a thermal or UV free radical initiator (optionally included in one or both of the oil or water phases) and an organic acid into an internal phase oil; heating or UV exposing for a time (and temperature) sufficient to oligomerize the amine modified polyfunctional polyvinyl monomer and oil soluble bi- or polyfunctional vinyl monomer forming a pre-polymer. Thereafter the process involves adding to the oil phase oil a water phase comprising a dispersion in water of an anionic emulsifier (and optionally initiator), and adding an emulsifying agent. Emulsifying the water phase into the oil phase (W/O) is controlled through the quantity of water employed.
