A self-emulsifying composition contains: 70 to 90% by weight in total of one or more compounds selected from the group consisting of ω3 polyunsaturated fatty acids and their pharmaceutically acceptable salts and esters; 1 to 29% by weight of an emulsifying agent selected from among a polyoxyethylene sorbitan fatty acid ester, a sorbitan fatty acid ester, a glycerin fatty acid ester and a polyoxyl castor oil; and 0.5 to 6% by weight of water when the composition is defined to be 100% by weight as a whole. The self-emulsifying composition is excellent in self-emulsifying property, composition dispersibility, emulsion stability, and absorbability, is free from ethanol and polyhydric alcohols or only has such an alcohol added thereto at a reduced concentration, and is useful for foods and pharmaceuticals.

The present invention relates to droplet-based washing. According to one embodiment, a method of providing a droplet in contact with a surface with a reduced concentration of a substance is provided, wherein the method includes: (a) providing a surface in contact with a droplet comprising a starting concentration and starting quantity of the substance and having a starting volume; (b) conducting one or more droplet operations to merge a wash droplet with the droplet provided in step (a) to yield a combined droplet; and (c) conducting one or more droplet operations to divide the combined droplet to yield a set of droplets comprising: (i) a droplet in contact with the surface having a decreased concentration of the substance relative to the starting concentration; and (ii) a droplet which is separated from the surface.

A process for preparing an alkylene oxide, which process comprises:(i) oxidizing an alkylbenzene to obtain a stream comprising alkylbenzene hydroperoxide,(ii) contacting at least part of the alkylbenzene hydroperoxide obtained in step (i) with an olefin to obtain a product stream comprising an alkylene oxide(iii) separating alkylene oxide compound from the product stream of step (ii) to obtain (a) a residual product stream comprising alkylphenyl alcohol, and (b) alkylene oxide,(iv) feeding at least a part of the residual product stream comprising alkylphenyl alcohol to a reactor having a catalytic distillation zone, and concurrently in the reactor,(a) contacting the residual product stream comprising alkylphenyl alcohol with hydrogen in the catalytic distillation zone to convert the alkylphenyl alcohol in the residual product stream to alkylbenzene and form a reaction mixture, and(b) separating alkylbenzene from the reaction mixture by fractional distillation,(v) withdrawing a stream comprising alkylbenzene and having a reduced concentration of alkylphenyl alcohol than the feed stream from the reactor at a position upper from the catalytic reaction zone;(vi) withdrawing from the reactor at a position lower than the catalytic distillation zone a bottom stream comprising dimer(s) of alkylbenzene;(vii) converting the dimer(s) of alkylbenzene in the bottom stream from (vi) to alkylbenzene; and(viii) recycle at least a part of the alkylbenzene produced from (iv)(b) and / or (vi) to step (i).

The invention relates to compositions and methods for isolation of microvesicles produced by mammalian cells. These microvesicles, known as extracellular microvesicles or circulating microvesicles, are isolated from sample materials such as body fluids, or from cell culture media that has been used to culture and maintain mammalian cells in vitro. The isolation of microvesicles as described herein results in purification and concentration of the microvesicles.The invention also provides related methods for producing blood serum and / or blood plasma that is free of detectable microvesicles, largely depleted of microvesicles, or has reduced concentration of microvesicles compared to the blood serum or blood plasma starting material (collectively termed “microvesicle-depleted”). The generation of microvesicle-depleted blood serum or plasma is critical for use in experimental systems where it is desirable to use a cell culture media that does not contain endogenous microvesicles, or has been depleted of endogenous microvesicles, from the source material.
