The work aims to study the Phthalate Acid Esters (PAEs) plasticizer in food contact silicone rubber products (FCSRPs) marketed in China and their migration and exposure to the infant milk powder, to provide theoretical support and scientific basis for the safety study of FCSRPs. Sixteen PAEs in 32 FCSRPs marketed in China were detected by ultrasonic solvent extraction-gas chromatography-tandem mass spectrometry (UASE-GC-MS/MS). In particular, a QuEChERS-GC-MS/MS method was established and used to study the migration of PAEs in silicone rubber milk cups. Five PAEs (DBP, DIBP, DEHP, DEP, DMP) were detected in 32 FCSRPs, and the content of PAEs varied greatly among different samples. The EDI values of the five PAEs for children of different ages were all below 10 μgžkg-1žbw-1žday-1. This study provided data and theoretical support for the study of PAEs in FCSRPs and other materials. PAEs are generally detected in FCSRPs and the exposure values of five PAEs ingested by infants through using silicone rubber cups are below the limit value.
