Abstract:
Catalysts useful for oxidation reactions are disclosed. The catalysts comprise a polymer-encapsulated titanium zeolite. The catalysts are easy to prepare and use, they are easy to recover and reuse, and they provide good conversions in a variety of important oxidation processes. The invention includes a process which comprises oxidizing an organic compound in the presence of hydrogen peroxide and a polymer-encapsulated titanium zeolite. In one example, the organic compound is propylene and the reaction product is propylene oxide. ® KIPO & WIPO 2007
Abstract:
Catalysts useful for oxidation reactions are disclosed. The catalysts comprise a titanium zeolite, a transition metal, and a polymer, wherein at least one of the titanium zeolite or transition metal is encapsulated within a thin layer of the polymer. The catalysts are easy to prepare and use, they are easy to recover and reuse, and they provide good conversions in a variety of important oxidation processes, including propylene epoxidation. The invention includes a process which comprises oxidizing an organic compound in the presence of hydrogen, oxygen, and the catalyst, wherein the transition metal catalyzes formation of hydrogen peroxide in situ. ® KIPO & WIPO 2007
Abstract:
Vesicle and microemulsion compositions comprising a silicone surfactant, a co-surfactant, a polar organic oil, and water are disclosed. A method for forming vesicles from a microemulsion comprising a silicone surfactant, a co-surfactant, a polar organic oil, and water is also disclosed. The vesicle and microemulsion compositions are useful in a variety of personal care applications.
Abstract:
The present invention relates to microcapsules delivering long lasting and intense vanilla-based odor note. More particularly, the present invention concerns a microcapsule comprising between 10% and 30% by weight, relative to the total weight of the microcapsule, of a particular perfuming ingredient imparting a vanilla-based odor note, which can be used in perfuming compositions and perfuming consumer products.
Abstract:
Disclosed herein are a method for producing a miniaturized liposome on a large production scale, and an apparatus for producing a liposome which is to be used in the above-mentioned method. Provided is a method for producing a liposome, including a step of stirring a mixture containing an oil phase in which at least one lipid is dissolved in an organic solvent and a water phase in a first tank of an apparatus having the first tank and a circulation path, in which the ratio of the capacity of the circulation path to the total capacity of the tank and the circulation path is 0.4 or less and/or the time required for the mixture to return to the first tank after being discharged therefrom is within 2.0 minutes.
