Currently, widespread concerns have been raised regarding food contamination caused by the migration of photoinitiators in food packaging materials. This article presented a review of the research on different volatile photoinitiators and their applications as standard substances both domestically and internationally. Based on the research focus, several compounds were selected as representatives of highly volatile and less volatile photoinitiators, including benzophenone (BP), 4-methylbenzophenone (4-MBP), ethyl 4-(dimethylamino)benzoate (EDB), 1-hydroxycyclohexyl phenyl ketone (PI-184), methyl-o-benzoylbenzoate (OMBB), 2,2-dimethoxy-2- phenylacetophenone (PI-651), 2-ethylhexyl-4-(dimethylamino)benzoate (EHA) and 2-isopropylthioxanthone (2-ITX). This paper summarized the mechanisms of photoinitiators migration and contamination, discussed analytical detection methods, compared the types of sample matrices used in the contamination and migration studies of different volatile photoinitiators both domestically and internationally, also analyzed the proportion of standard substances used in domestic and international research, their sources, and the demand for new standard substances. It was found that the current national standard substance resource sharing platform provides the most extensive collection of BP and ITX standard substances for photoinitiators research; however, it was recommended that other widely discussed photoinitiators, such as EDB, PI-651, PI-184 and OMBB, be included in new planning. Suggestions for the development of standard substances for photoinitiators in China were provided in this article, offering broader technical support for the study of photoinitiators contamination in the country.
