Patent number: 10869947Abstract: Hydrogel compositions are provided (a) that have a continuous hydrophobic phase and a discontinuous hydrophilic phase, (b) that have a discontinuous hydrophilic phase and a continuous hydrophilic phase, or (c) that are entirely composed of a continuous hydrophilic phase. The hydrophobic phase, if present, is composed of a hydrophobic polymer, particularly a hydrophobic pressure-sensitive adhesive (PSA), a plasticizing elastomer, a tackifying resin, and an optional antioxidant. The discontinuous hydrophilic phase, if present, is composed of a crosslinked hydrophilic polymer, particularly a crosslinked cellulosic polymer such as crosslinked sodium carboxymethylcellulose. For those hydrogel compositions containing a continuous hydrophilic phase, the components of the phase include a cellulose ester composition or an acrylate polymer or copolymer, and a blend of a hydrophilic polymer and a complementary oligomer capable of hydrogen bonding thereto.Type: GrantFiled: April 29, 2014Date of Patent: December 22, 2020Assignees: Corium, Inc., A.V.

Patent number: 10866164Abstract: A biodegradable sampling bag for containing samples or the like, comprises a flexible enclosure defining a chamber adapted to contain therein the sample, the flexible enclosure being made of a plastic material, which contains an additive that renders the flexible enclosure biodegradable when exposed for a sufficient period of time to microbial action. The additive is adapted to enable microorganisms to metabolize the molecular structure of said flexible enclosure. The additive is effective in altering the polymer chain of the plastic material to allow microbial action of a suitable environment to colonize in and around the plastic material, whereby microbes can then form a biofilm on a surface of the flexible enclosure and secrete acids which break down the entire polymer chain. The flexible enclosure, when exposed to microbial action, is adapted to withstand biodegradation for a given period of time, typically of at least three months.Type: GrantFiled: October 21, 2019Date of Patent: December 15, 2020Assignee: LABPLAS INC.Inventors: May L.

Publication number: 20150107488Abstract: A composition which, when mixed with a polymer composition, allows for the formation of a continuous and cohesive film. The film is characterized in that it provides water, grease and oil resistance, provides a water vapour barrier and can used as wax replacement treatment and a top coat for flexible packaging, but also on other substrates. This film is formed at a very fast set speed without the need of thermal energy. The composition contains i) calcite alone or in combination with a salt of one or more of myristic, palmitic and stearic acid; and also ii) a C9-C18 fatty acid complex of a metal ion, the metal ion having an oxidation state of at least 3. The composition is incorporated in material such as cellulose based material or plastic based material.Type: ApplicationFiled: December 21, 2012Publication date: April 23, 2015Inventors: François Dandenault, Djamel Baghdad Daidj, Serge Bérubé, Shoreh Parandoosh
