(57) Abstract As for this invention, next formula (i): [In upper formula: As for Y displaying oxygen atom or NH basis; As for A with direct condition, branching condition or annulation, displaying C₁ - C₁₂ arukanjiiru bases of saturation or unsaturated; As for the said basis, one or the multiple hetero atoms may be interposed, and/or: Amino (- NH₂): The acylamino (- NH-CO-R) with, R with direct condition, branching condition or annulation, those which display C₁ - C₁₀ alkyl groups of saturation or the unsaturated: Carboxylic acid (- COOH): Ester (- COOR) with, R with direct condition, branching condition or annulation, regards application it is possible to be displacement with the functional group which is chosen from those which display C₁ - C₁₀ alkyl groups of saturation or the unsaturated], as a membrane formation medicine of one which is chosen from poly branching polymers and dendorima which at least possess one basis chemical compound at least. In addition as for this invention, the constituent for membrane formation which contains the said chemical compound, it regards the application in the especially those cosmetics or the medical supply.
