Abstract: In one aspect, the present disclosure provides a complex containing kojyl methylenedioxycinnamate; a compound containing an ethylene glycol moiety or a propylene glycol moiety; a surfactant containing a saccharide moiety; and an antioxidant, and an emulsion formulation containing the complex. In another aspect, the present disclosure provides a method for manufacturing the complex, comprising: (a) adding kojyl methylenedioxycinnamate, a compound containing an ethylene glycol moiety or a propylene glycol moiety, a surfactant containing a saccharide moiety, and an antioxidant; and (b) homomixing the result of the (a).

Abstract: An object of the present invention is to provide the tocopherol derivatives represented by the following formula (I), and their salts: Wherein, R1, R2 and R3 are H or methyl group, and at least one positions selected from group consisting of the R1, R2 and R3 positions are methyl group; and, A is CH2—CH(CH3)— or CH═C(CH3)— The other object of the present invention is to provide a method for preparing the above tocopherol derivatives. The tocopherol derivatives is prepared by reacting tocopherol with phosphorous oxychloride in an equivalent ratio of 1:1˜1.3, in presence of an organic base, in an organic solvent; reacting the tocopherol dichlorophosphate produced by the above reaction with 3-aminopropanol in presence of an organic base, in an organic solvent; and, hydrolyzing the above products.
