For example, 1173 has a molecular weight of 164.2, TPO has 348.4, and 819 has 418.5, all classified as low-molecular-weight organic compounds.Under incomplete light exposure, these photoinitiator molecules may remain in the cured material, forming potential migration substances. Furthermore, the generation of free radicals by photoinitiators is predominantly achieved through cleavage reactions. These free radicals may form lower molecular weight compounds upon final quenching.These small-molecule products not only contribute to migration concerns but may also generate toxic substances. Both residual photoinitiators and the small molecules produced during reactions pose potential migration risks in light-cured products, potentially adversely affecting users.The most significant incident occurred in 2005 when the photoinitiator ITX was detected in Nestl\u00e9 infant formula in Italy.
