  • Patent number: 11914295
    Abstract: The present invention is a thermosetting silicon-containing material containing one or more of a repeating unit shown by the following general formula (Sx-1), a repeating unit shown by the following general formula (Sx-2), and a partial structure shown by the following general formula (Sx-3): where R1 represents an iodine-containing organic group; and R2 and R3 are each independently identical to R1, a hydrogen atom, or a monovalent organic group having 1 to 30 carbon atoms. This provides: a thermosetting silicon-containing material used for forming a resist underlayer film which is capable of contributing to sensitivity enhancement of an upper layer resist while keeping LWR thereof from degrading; a composition for forming a silicon-containing resist underlayer film, the composition containing the thermosetting silicon-containing material; and a patterning process using the composition.

  • Patent number: 9648938
    Abstract: This application aims at providing a retainer of a cosmetic material and a method of manufacturing a cosmetic tool, which are capable of easily treating the cosmetic material even when decreasing a concentration of skin care ingredients of the cosmetic material produced by freeze-drying. A cosmetic tool (1) includes: a retainer (3) to include an annular frame (2) and a handle (5) for holding the frame (2); and a cosmetic material (4) to be produced by freeze-drying an aqueous solution of skin care ingredients and fixed in a way that covers an aperture of the frame (2).

  • Patent number: 9238688
    Abstract: Disclosed is a compound which exhibits a higher effect of preventing wrinkle formation, a higher effect of improving wrinkles, a higher effect of making the skin beautiful, and a higher effect of improving skin quality than conventional retinol and retinol derivatives in a sustained manner. Further disclosed are a method for producing the same, and an external composition for the skin and a sheet-shaped cosmetic each containing the same as an active ingredient. More specifically disclosed are retinol-modified collagen in which a dicarboxylic acid is attached to at least one hydroxyl group of collagen and retinol is attached to a carboxyl group of at least one attached dicarboxylic acid, a method for producing the same, and an external composition for the skin and a sheet-shaped cosmetic each containing the same as an active ingredient.
