  • Publication number: 20170238576
    Abstract: A gum base comprises nanoparticles and/or non-uniform microparticles containing at least one crosslinked polymer. Non-uniform microparticles may be in the form of polymer composite microparticles, hollow shell microparticles and/or core-shell microparticles. It has been found that such gum bases exhibit desirable chewing properties similar to conventional gum bases. Cuds formed by chewing gum bases containing crosslinked polymer microparticles are easily removable from environmental surfaces such as concrete, fabrics and flooring materials.

  • Publication number: 20170199179
    Abstract: Described herein are methods of catalyzing oxidation reactions by an oxidizing agent (e.g., hydrogen peroxide). The methods include contacting a substrate with an oxidizing agent and a nanoparticle in a reaction mixture, wherein the nanoparticle comprises a Pd core at least partially surrounded by a coating comprising Ir. In addition, disclosed herein are kits for catalyzing the oxidation of a substrate by an oxidizing agent. The kits include a substrate, an oxidizing agent, and a nanoparticle, wherein the nanoparticle comprises a Pd core at least partially surrounded by a coating comprising Ir. The kits also include instructions describing how to contact the substrate, the oxidizing agent and the nanoparticle so as to catalyze the oxidation of the substrate.

  • Publication number: 20150150279
    Abstract: The present invention provides gum bases and chewing gums, as well as methods of manufacturing the gum bases. More specifically, the gum bases provided herein contain microparticles comprising a crosslinked polymer selected from the group consisting of crosslinked polyvinyl alkanoates, crosslinked polyvinyl alkenoates, crosslinked polyvinyl aryloates, crosslinked polysiloxanes, and copolymers and mixtures. The microparticles render a gum cud comprising the gum base more easily removable from surfaces onto which it may become adhered than gum cuds comprising conventional gum bases.

  • Patent number: 8617623
    Abstract: A chewing gum comprises a primary chewing gum composition comprising gum base, a sweetener and a flavoring agent and a food acceptable delayed-release modification agent. The delayed-release modification agent reacts with the primary chewing gum composition after a chewed cud of the gum composition is formed, causing the primary gum to exhibit increased environmental acceptability after the chewed cud is discarded.

  • Patent number: 8414939
    Abstract: A composition includes a first component containing phospholipids and a second component encapsulating the first component. The composition includes between about 10% and about 80% by weight phospholipids. The composition may be used in chewing gum to provide a gum cud that does not adhere to concrete and does not dissolve in the mouth while chewing.

  • Publication number: 20130052301
    Abstract: A chewing gum base which is cud-forming and chewable at mouth temperature contains a food acceptable tri-block copolymer having the form A-B-A or A-B-C and comprising a soft mid-block which constitutes at least 30 wt. % of the total polymer and hard end-blocks each having a glass transition temperature below 70° C. The tri-block copolymer is optionally plasticized with a compatible di-block copolymer to function as an elastomer system in the gum base.

  • Publication number: 20120269924
    Abstract: A chewing gum, when chewed, produces a cud having improved removability from environmental surfaces by virtue of its linear viscoelastic shear rheology. The cud has a specified temperature dependent storage modulus differential (? log G?/?T) at 25° C. and 60° C. Specifically, the cud has a temperature dependent storage modulus differential less than 0.050.

  • Patent number: 8048450
    Abstract: An aqueous dispersion of hydrogel nanoparticles and methods of making the aqueous dispersion of hydrogel nanoparticles having an interpenetrating polymer network (“IPN”) are described. The uniformed sized mono-disperse IPN nanoparticles have inverse thermo gelation properties that allow therapeutic medications to be uniformly distributed in a liquid form of the aqueous dispersion of hydrogel nanoparticles. Such medications can then be released from a solid form of the aqueous dispersion of hydrogel nanoparticles in time dependant manor.
