  • ACTIVATOR INCLUDING BIOSURFACTANT AS ACTIVE INGREDIENT, MANNOSYL ERYTHRITOL LIPID, AND PRODUCTION METHOD THEREOF
    Publication number: 20100228013
    Abstract: The present invention includes as an active ingredient at least one biosurfactant, in particular mannosyl alditol lipid (such as MEL and MML) or triacylated mannosyl alditol lipid. This allows providing an activator and anti-aging agent that is excellent in activating and anti-aging effects on cells and that is safe enough to be used for a long time, and also providing cosmetics, quasi-drugs, drugs, and drinks and foods including the activator and the anti-aging agent as active ingredients. Further, the present invention provides MEL whose mannosyl erythritol skeleton in a molecular structure is 1-O-?-D-mannopyranosyl-meso-erythritol and a method for producing the MEL with use of a microorganism.

  • Process for producing liposome and apparatus therefor
    Publication number: 20040099976
    Abstract: A method for producing liposome encapsulating a desired substance is provided. The method is characteristic in that an aqueous phase containing the substance to be encapsulated is added to a homogenous fluid mixture of a phospholipid or a glycolipid and carbon dioxide either under a supercritical condition or under a condition in which temperature or pressure is higher than or equal to its critical point. This method makes it possible to produce liposomes with improved trapping efficiency in fewer steps and without using harmful organic solvents.
