Provided is a lubricating composition for inhibiting plugging including a base oil and any one selected from a fatty acid and an emulsifier, with the lubricating composition forming a single phase even when a carboxylic acid-based monomer is introduced with respect to the base oil. The lubricating composition suppresses plugging occurring in a process of preparing a copolymer derived from the carboxylic acid-based monomer. In addition, also provided is a method of inhibiting plugging using the lubricating composition for inhibiting plugging.
