MANUFACTURING METHOD OF ENVIRONMENT-FRIENDLY POLYESTER USING 2,3-BUTANEDIOL MANUFACTURED BY DECOMPOSING GLYCEROL EXTRACTED FROM THE NATURE WITH ENZYME, AND A NAIL CARE COMPOSITION CONTAINING THE ENVIRONMENT-FRIENDLY POLYESTER

摘要

PURPOSE: A manufacturing method of environment-friendly polyester is provided to be able to manufacture environment-friendly polyester providing a nail care composition which is easy to put on nail, has excellent strength and glossiness of the pellicle on nail, and is not easy to be exfoliated.;CONSTITUTION: A manufacturing method of environment-friendly polyester comprises a mixing step of putting 2,3-butanediol and adipic acid in a reactor (S102); a monomer putting step of putting multifunctional monomer into the mixture mixed in the mixing step (S103); a heating reaction step of reacting by heating the mixture in which multifunctional monomer is put (S105); a cooling step of cooling the polymer manufactured through the heating reaction step (S107); and a solvent feeding step of putting a solvent in the polymer having passed through the cooling step (S109).;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Start; (BB) End; (S101) Mixing step; (S103) Monomer putting step; (S105) Heating reaction step; (S107) Cooling step; (S109) Solvent feeding step
