To provide an efficient method for producing a non-cross-linked cyclic oligosaccharide-modified organopolysiloxane soluble in solvents despite its high molecular weight, by removing unreacted cyclic oligosaccharides.SOLUTION: A method for producing a cyclic oligosaccharide-modified organopolysiloxane comprises the following steps: [Step 1] obtaining an oligosaccharide-modified organopolysiloxane by hydrosilylation of a composition containing (A) to (D) in the following, namely, (A) an organohydrogen polysiloxane having one or more hydrosilyl groups per molecule having a kinematic viscosity of 50 mm2 / s or more at 25°C and a number average molecular weight of 8,000 or more, (B) a cyclic oligosaccharide derivative having an unsaturated group represented by the specified general formula (1), (C) a hydrosilylation catalyst, and (D) an organic solvent; [Step 2] cleaning and filtering the cyclic oligosaccharide-modified organopolysiloxane obtained in the Step 1 with a cleaning organic solvent having a relative permittivity of 23 or more at 25°C or a mixture of such solvents; and [Step 3] removing the organic solvents used in the Steps 1 and 2.SELECTED DRAWING: None

This invention discloses a method for preparing and applying aescin in cosmetics, belonging to the field of plant active ingredient extraction technology. The method for preparing aescin includes the following steps: adding horse chestnut seeds to an organic solvent, then adding an alkaloid, heating and refluxing to extract, and then removing the organic solvent to obtain a crude extract; dissolving the crude extract in water, adding a cyclic oligosaccharide, stirring and reacting, then adding an organic acid, heating and reacting, and finally purifying to obtain aescin. The preparation method of this invention can improve both the extraction rate and retention rate of aescin.

The present invention provides a composition and a method for improving physical stability of a biopharmaceutical. The present invention involves adding a specific electrolyte (a salt, an acid, or a base, which is in the form of an ion or the like in the present disclosure) and / or cyclodextrin to a dispersive medium for proteins. The present disclosure provides a protein preservative comprising a cyclic oligosaccharide, and at least one electrolyte selected from inorganic salts, organic salts, organic acids, and organic bases, or an ion of the electrolyte.

An ionic solid having pores may be useful for incorporating a substance therein. Such an ionic solid may have pores for incorporating a substance therein. The pores may be formed by a crystal lattice of a metal complex. A hydrophilic substance having a molecular weight of 60 or larger may be included in the pores. The hydrophilic substance may be selected from a polyhydric alcohol, a cyclic oligosaccharide, a saccharide, a sugar alcohol, and an amino acid. The hydrophilic substance may be a guest compound.

A pressure sensitive adhesive sheet includes at least a pressure sensitive adhesive layer, wherein a pressure sensitive adhesive constituting the pressure sensitive adhesive layer is an emulsion-type pressure sensitive adhesive containing a cyclic oligosaccharide, and an adhesive strength to soda-lime glass is 5 N / 25 mm or more. The above emulsion-type pressure sensitive adhesive is preferably an emulsion-type acrylic-based pressure sensitive adhesive.
