Monoacylglyceride (MAC) is an important nonionic surfactant. It contains an oleophilic long chain alkyl group and two hydrophilic hydroxyl groups, so it has good surface activity and can be used as emulsifier in food, cosmetics, medicine and other fields. Recent studies have found that some monoglyls exhibit certain antibacterial properties, which makes the research and development of monoglyls have important application value
