A hyaluronic acid product is comprising a cross-linked hyaluronic acid and one or more cyclodextrin molecules, and further comprising a guest molecule capable of forming a guest-host complex with the aminocyclodextrin molecule acting as a host, wherein the guest molecule is a retinoid, preferably adapalene, or a RAM BA. The hyaluronic acid is cross-linked by ether bonds, and the one or more cyclodextrin molecules are grafted onto the cross-linked hyaluronic acid by amide bonds, preferably using a triazine-based coupling reagent.

The invention is a composition that can prevent formation in, or scavenge undesirable organic materials from, a polymer matrix. The composition contains cyclodextrin and particles of activated carbon. The composition can scavenge thermal decomposition products that can be produced during melt processing of a polymer, contaminants inherent in a polymer, or other types of impurities from a polymer matrix that otherwise may elute into the air, a water supply, or an ingestible material such as a food, a drug, or a beverage. Other aspects of the invention are blends of the composition with polymeric materials, methods of making blends, articles containing the composition, and methods of making articles containing the composition.

A method for preparing a sustained release antibacterial film includes: (1) mixing a cyclodextrin metal-organic framework (CD-MOF) material with a silver nitrate short-chain alcohol solution to prepare an intermediate material A; (2) mixing the intermediate material A with a caffeic acid short-chain alcohol solution to prepare an intermediate material B; (3) dispersing the intermediate material B in a solvent, adding a polydimethylsiloxane main agent and a PDMS auxiliary agent in sequence, and mixing well by stirring to obtain a casting solution; and (4) coating the casting solution on a film support material, conducting vacuum drying, and peeling off a film from the film support material to obtain the sustained-release antibacterial film. A mixed matrix-based film material in which the CD-MOF and the PDMS are physically blended is prepared based on CD-MOF and PDMS for the first time, and may be used in application researches of food, environment and other fields.

Cyclodextrin compositions including one or more radiation polymerizable monomers and a cyclodextrin inclusion complex, the cyclodextrin inclusion complex including a cyclodextrin compound and an olefinic inhibitor of an ethylene generation in produce, are coated onto packaging materials and cured. Treated containers and treated package inserts having the cured cyclodextrin compositions are useful in packaging of respiring plant materials.

The present invention relates to a degradable film for packaging fruit and vegetables, which comprises a polyolefin-based polymer matrix that incorporates an antimicrobial (biocidal or fungicidal) active ingredient of an essential oil, selected from the group consisting of: carvacrol, cinnamaldehyde, cineol, sabinene, thujaplicin, or a mixture of same, or incorporates the essential oil itself, selected from the group consisting of: cinnamon oil, oregano oil, eucalyptus oil, nutmeg oil, hinoki oil, or a mixture of same. The polymer matrix further comprises degrading agents. The invention also relates to a method for microencapsulating the antifungal or antibacterial active ingredients of the essential oil or the essential oil itself, and to a method for preparing the film.

The present disclosure provides a water-soluble 1,3-diphenylguanidine (DPG)-based supramolecular inclusion complex and a preparation method and use thereof. A supramolecular compound and a vulcanization accelerator DPG are subjected to supramolecular interaction to form a DPG-based supramolecular inclusion complex. While improving water solubility and dispersibility of the DPG, a molecular structure of the DPG can be completely retained, and the supramolecular host used does not affect a performance of latex. The supramolecular compound and the DPG are ball milled in a certain proportion to prepare the DPG-based supramolecular inclusion complex, the water-soluble DPG-based supramolecular inclusion complex is added in a natural latex curing process; and after mixing evenly, a mixture is foamed on-machine, vulcanized in a steamer, and dried to obtain a latex foam product. The latex product has significantly improved tensile strength and elongation at break, and reduced hardness, which is more healthy and hygienic, showing broad market prospects.

An article that repels animals includes a synthetic resin composition. The synthetic resin composition includes a first thermoplastic polymer. A master blend is combined with the first thermoplastic polymer. The master blend includes a second thermoplastic polymer. At least one odorant compound is selected from the group consisting of a salicylic acid ester, menthol, corn mint oil, eucalyptus oil, camphor oil, and combinations thereof. At least one scent extender compound includes at least one cyclodextrin compound, wherein a ratio by weight of the second thermoplastic polymer to a combination of the odorant compound and the scent extender compound is about 2:1. A method for forming a master blend, a method for forming a synthetic resin composition, and an article that repels animals including a synthetic resin composition are also described.

A conducting composition includes a topological polymer (e.g., a polyrotaxane polymer) and poly(3,4-ethylene-dioxy thiophene):polystyrene sulfonate (PEDOT:PSS). Devices may include a conducting layer including the conducting compositions, e.g., a device comprising a conducting layer, wherein the conducting layer includes a polyrotaxane polymer and a PEDOT:PSS array.
