  • Patent number: 5150722
    Abstract: Described are methods for effecting the controlled release of fragrance materials over a relatively long period of time for the purpose of air treatment and scenting. Optionally in the same time frame the methods can effect an initial "Burst" of the same or different organoleptic functional materials over a relatively short period of time. The air treatment agents can include but are not limited to insect repellents, air fresheners, odorants and deodorants. Also described are articles capable of being mass produced which are useful in effecting the controlled release of fragrances, insect repellents, air fresheners, odorants and deodorants over a relatively long period of time and, optionally, in the same time frame, effecting an initial "Burst" of the same or different organoleptic functional materials over a relatively short period of time. Also described is apparatus specifically designed to utilize such articles.

  • Patent number: 5116627
    Abstract: Described is a chewing gum comprising a chewing gum base having dispersed therein, separately, a multiplicity of sweetener bearing polymeric particles and/or flavor-bearing polymeric particles, said polymeric particles further comprising:(a) at least one water-soluble normally solid polymer;(b) at least one water-insoluble normally solid polymer;(c) and either(i) at least one flavor composition a substantial portion of which is incorporated in the water-insoluble polymer and a substantial portion of which is incorporated in the water-soluble polymer; and/or(ii) at least one sweetener composition a substantial portion of which is incorporated in the water-insoluble polymer and a substantial portion of which is incorporated in the water-soluble polymer;the water-soluble polymer and the water-insoluble polymer being physically associated with each other associated in such a manner that one is in the form of a multiplicity of discrete entities in a matrix of the other.

  • Patent number: 5070891
    Abstract: Articles for providing controlled release of materials such as flavoring and fragrance compositions into an environment, the articles comprising a core of a functional organoleptic composition dispersed within a first polymeric composition and a barrier polymer of a second polymeric substance covering a portion of the total surface area of the core or cores, the uncovered portion of the core directly contacting the environment around the article, with the average molecular weight of the functional composition being greater than 100, and the core comprising a water-soluble polymer mixed with a surfactant or fabric softener.

  • Patent number: 5069231
    Abstract: Described are methods for effecting the controlled release of the functional organoleptic materials, to wit:(a) perfumery materials;(b) insect attractants;(c) insect repellents;(d) animal repellents;(e) fabric softener compositions;(f) flavor materials;(g) surface active agents; and(h) insect pheromonesover a relatively long period of time and, in the same time frame, effecting an initial "Burst" of the same or different organoleptic functional materials over a relatively short period of time. Also described are articles useful in effecting the controlled release of such functional organoleptic materials over a relatively long period of time and in the same time frame effecting an initial "Burst" of the same or different organoleptic functional materials over a relatively short period of time.

  • Patent number: 4842761
    Abstract: Laundering compositions containing particulate olfactory polymers which provide for the controlled release of olfactory compositions such as perfumes, the particulate olfactory polymers comprising a water-soluble normally solid polymer, a water-insoluble normally solid polymer, and at least one olfactory composition which is in each polymer, one polymer being in the form of discrete entitles in a matrix of the other polymer, together with laundering articles such as packets containing such compositions; methods for laundering using such compositions; the particulate olfactory polymers; and methods for preparing the particulate olfactory polymers.

  • Patent number: 4543367
    Abstract: Described is a process for preparing extruded functional fluid and solid-containing thermoplastic foamed particles using chemical blowing agents or direct gas extrusion processes, uses of such foamed particles and articles produced from said foamed particles. The process described involves the use of a single screw or double screw extruder wherein the resin particles are added upstream from the functional fluid or solid which, in turn, is added to the extruder upstream from the point of addition of the liquid or gaseous blowing agent.

  • Patent number: 4542162
    Abstract: Described is a process for preparing extruded insect, animal or bird repellent fluid and solid-containing thermoplastic foamed particles using chemical blowing agents or direct gas extrusion processes, uses of such foamed particles and articles produced from said foamed particles. The process described involves the use of a single screw or double screw extruder wherein the resin particles are added upstream from the insect, animal or bird repellent fluid or solid which, in turn, is added to the extruder upstream from the point of addition to the liquid or gaseous blowing agent.
