  • Patent number: 7214382
    Abstract: This invention relates to cosmetic applications for topical applications to the human skin. In particular, it relates to anhydrous cosmetic and dermatological compositions, with the capacity for self-warming or self-heating upon application. The self-warming or self-heating cosmetic compositions of the present invention comprise: (i) from about 0.1 to about 99% by weight of an anhydrous skin care preparation; and (ii) from about 0.01 to about 99% by weight of a heating agent selected from polyvinyl amine, polyalkyleneamine or polyalkyleneimine.

  • Patent number: 7119060
    Abstract: The present invention relates to a controlled delivery system that can be incorporated in liquid, as well as, dry granular, or powder, fabric care products, such as fabric softeners, laundry detergents, rinse added products, and other fabric care products, to enhance fragrance performance. The controlled delivery system of the present invention is a solid, substantially spherical particle comprising hydrophobic cationic charge enhancing agents in conjunction with cationic fabric softening agents that assist in adhering the particles onto fabric. The particles can also include a fragrance. The particle can have an average particle diameter of from about 1 micron to about 500 microns. The controlled delivery system of the present invention can be utilized to deliver a broad range of fragrance ingredients onto fabric and prolong fragrance release from the dry laundered fabric over an extended period of time, or yield a high impact fragrance “burst” upon ironing the fabric.

  • Patent number: 6979440
    Abstract: The present invention is a controlled delivery system that can be incorporated in hair, skin, and fabric care products such as shampoos, conditioners, hair styling products, lotions, creams, liquid laundry detergents, fabric softener, and other hair, skin, and fabric care products to effectively deliver a broad range of active agents and sensory markers onto the hair, skin, and fabric. The system also prolongs the release rate of the active agents or sensory markers over an extended period of time, or provides heat triggered release of the active agents and yields a high impact fragrance “burst” upon blow drying the hair, ironing the fabric, or other types of heat treatment. The controlled delivery system of the present invention is a nano-sphere, having an average sphere diameter of from about 0.01 microns to about 10 microns.

  • Patent number: 6887493
    Abstract: The present invention relates to an improved controlled release system that can encapsulate different flavors, sensory markers, and active ingredients, or combinations of flavors, sensory markers and various active ingredients and release multiple active ingredients in a consecutive manner, one after the other. The controlled delivery system of the present invention is substantially free-flowing powder formed of solid hydrophobic nanospheres that are encapsulated in a moisture sensitive microspheres. The flavors, and active ingredients encapsulated in the hydrophobic nanospheres, in the water sensitive microsphere, or in both the nano and the microsphere. The flavors and active ingredients encapsulated in the nanospheres can be the same or different from those encapsulated in the microspheres.

  • Patent number: 6740631
    Abstract: The present invention relates to an improved controlled delivery system that can be incorporated in dry granular, or powder, fabric care products, such as laundry detergents, tumble dryer sheets, rinse added products, and other fabric care products, to enhance fragrance performance. The controlled delivery system of the present invention comprises substantially free-flowing, powder formed of solid hydrophobic, positively charged, nano-spheres of encapsulated active ingredients, such as a fragrance, that are encapsulated in a moisture sensitive micro-spheres, solid spheres. The high cationic charge density of the nano-sphere improves fragrance deposition onto the laundered fabric.
