I'm a star employee at CHROM&#xC9;CLAIR, a brand of hema free gel polish.Today, I'll organize some information about the migration and toxicity of photoinitiators, hoping it will be helpful to you.The molecular weight of photoinitiators typically ranges between 100 and 300. 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&#xE9; infant formula in Italy. Globally, the European Union maintains the strongest focus on the health impacts of chemicals and enforces the most stringent regulations.</description><thumbnail_url>https://changhongchemical.com/wp-content/uploads/2025/10/1-8.webp</thumbnail_url><thumbnail_width>3462</thumbnail_width><thumbnail_height>2084</thumbnail_height></oembed>
