  • Skin Cell Activator Extracted From Liver Of Fish Or Shellfish And Hair Growth Agent Using The Same
    Publication number: 20090131522
    Abstract: Disclosed are a skin cell activator extracted from a pufferfish liver, and a hair growth agent comprising 10 volume % or more of the skin cell activator. The skin cell activator comprises an organic substance which contains an alcohol- and other organic solvent-soluble fat/oil component extracted from a pufferfish liver, or a high-polar organic substance which has the fat/oil component and a hydrophilic reactive group selected from a group including a carboxyl group and a hydroxyl group and bound to the fat/oil component. The present invention makes it possible to effectively utilize an internal organ of a fish or shellfish which has conventionally been precluded from utilization. In particular, based on clarification of the hair growth-promoting function of the pufferfish's internal organ, the present invention can provide a novel hair growth agent having a direct hair-growing effect by utilizing the function.
