Notes on other potential health effects and hazards:
- A 2003 publication mentioned anecdotal complaints of testicular atrophy in men and menstrual irregularities in women exposed to TGIC during powder paint coating work. However, no medical data to support these claims were provided (Allmaras 2003).
- The substance may cause effects on the central nervous system, kidneys, liver, lungs and gastrointestinal tract, resulting in tissue lesions (NIOSH/IPCS 2001).
- TGIC forms adducts with DNA and has tested positive in mutagenicity/genotoxicity tests (Lindell and Montelius 2001).
- Allergic contact dermatitis has been reported in several case studies of occupational exposure to triglycidyl isocyanurate (ACGIH 2001; WHO 1998).
- Occupational asthma has been reported in several case studies of exposure to triglycidyl isocyanurate (Anees et al. 2011; Meuleman et al. 1999; Piirilä et al. 1997; Sastre et al. 2011).
