Publication number: 20110159103Abstract: Hydrophobic liquids are microencapsulated by an enteric matrix in an environment substantially free of organic solvents. The process includes forming an emulsion of the enteric material and hydrophobic liquid in water, titrating the emulsion with an acid to form a particulate precipitate and optionally coating the particulate with a combination of enteric material and plasticizer.Type: ApplicationFiled: December 22, 2010Publication date: June 30, 2011Applicant: KRAFT FOODS GLOBAL BRANDS LLCInventors: Ahmad Akashe, Anilkumar Ganapati Gaonkar, Les Lawrence, Amado R. Lopez, George W. Haas, Dana Sebesta, Yan Wang

Patent number: 7947370Abstract: The invention relates to microcapsules made of a core which contains at least one rubber additive and of a shell made of a first polymer. At least one coating made of a second polymer, which differs from the first polymer, and/or of a low molecular inorganic or organic compound, is deposited on the surface of the microcapsules as sliding or wearing layer in order to reduce the static friction.Type: GrantFiled: September 4, 2003Date of Patent: May 24, 2011Assignee: Schill + Seilacher GmbHInventors: Monika Jobmann, Gerald Rafler, Jozef Sagala, Ingeborg Gross

Patent number: 7943067Abstract: The present invention includes a method for preparing polymer hydrogel spherical particles on a nanometer scale (nanogels). The method includes encapsulating hydrogel-forming components into liposomes, diluting the large unilamellar liposomes suspension to prevent polymerization outside the liposomes, and polymerizing the encapsulated hydrogel-forming components. The lipid bilayer may be solubilized with detergent. The phospholipid and detergent molecules and their micelles may then be removed by dialysis. The resulting nanogels may then be dried by evaporation in a temperature gradient. Poly(acrylamide), poly(N-isopropylacrylamide), and poly(N-isopropylacrylamide-co-1-vinylimidazole) hydrogel particles with a diameter from 30 to 300 nm were detected and characterized by dynamic light scattering technique. The solvent, temperature, pH, and ionic sensitivities of the nanogels were studied.Type: GrantFiled: August 14, 2002Date of Patent: May 17, 2011Assignee: Polytechnic Institute of New York UniversityInventors: Sergey Kazakov, Marian Kaholek, Kalle Levon
