Abstract: A plasticizer, which is biodegradable, has a molecule including a central structure, at least two connecting structures and at least one side-chain structure. The central structure includes at least one of a benzene derivative and at least one amino acid. The connecting structures are respectively connected to the central structure, wherein the connecting structures include a first connecting structure and a second connecting structure. The first connecting structure is an amine group, and the second connecting structure is a carboxyl group. The side-chain structure is a chain of multiple carbon atoms, and the side-chain structure is connected to at least one of the first connecting structure and the second connecting structure. An amide bond is formed as the side-chain structure connected to the amine group, and an ester bond is formed as the side-chain structure connected to the carboxyl group.

Abstract: A plasticizer, a plastic composition and a plastic product are provided. The plasticizer is an amino acid derivative and has a biodegradability, wherein the plasticizer includes a central structure and at least one side chain structure. The central structure is an aspartic acid, the at least one side chain structure includes a first side chain structure and a second side chain structure. The plasticizer has a structure represented by Formula (I), in which each of the symbols thereof is as defined in the specification.
