Provided is a conductive material dispersion liquid for a lithium-ion secondary battery positive electrode, containing a conductive material, methyl octyl cellulose, and a dispersion medium.

A method for production of anti-microbial orthodontic elastomeric ligatures is disclosed. The elastomeric ligatures are coated with an anti-microbial solution layer by layer. The coating solution comprising an anti-bacterial agent, a polymer and a solvent in the following ratio: 2 g anti-microbial agent, 4 g polymer and 200 mL solvent. The hypo-allergic latex-free orthodontic elastomeric ligatures with an internal diameter of 0.045 inches and external diameter of 0.115 inches are rinsed in distilled water, dried at 60° C. and sprayed with the anti-bacterial solution two times and dried for five minute. This process is repeated for five times and the elastomeric ligatures are dried at room temperature for 1 h.

The invention provides hydrogel, wherein the hydrogel has a supramolecular cross-linked network obtainable or obtained from the complexation of an aqueous composition including a host, such as cucurbituril, and one or more polymers having suitable guest functionality. One or more polymers in the aqueous composition may have a molecular weight of 50 kDa or more, such as 200 kDa or more. The hydrogel may hold a component, such as a therapeutic compound or a biological molecule. The hydrogels are suitable for use in medicine.

The present invention provides a simple method for producing a medical/cosmetic sheet that is excellent in adhesion to skin or the like and sense of wearing, and is capable of releasing a functional component gradually and supplying it continuously to a treatment area or the like, and a medical/cosmetic sheet produced by this production method. Provided is a method for producing a medical/cosmetic material including a step of shaping a raw material containing a water-soluble salt of a first polyanionic polysaccharide having a viscosity-average molecular weight of 10,000 or lower, and a water-soluble salt of a second polyanionic polysaccharide having a viscosity-average molecular weight of 50,000 or higher, and thereby obtaining a water-soluble shaped body. A medical/cosmetic material produced by this production method is also provided.
