  • 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.

  • Patent number: 6027485
    Abstract: Medium members such as thread are provided between woven fabric sheet such as warp knitting serving as the other sheet and base member, forming linear raised portions in the woven fabric sheet. The density of woven fabric sheet at the inclined portions to either side of these raised portions becomes coarse and the gaps between fine filaments on the woven fabric sheet spread, so that retaining heads of one sheet can easily enter and so that the fine filaments easily become hooked to the base portion of the retaining heads. Consequently, the retaining of the one sheet and the other sheet in strengthened, and the peeling strength is improved.
