  • Are DEHP-alternative plasticizers cytotoxic?
  • In vitro cytotoxic effects of DEHP-alternative plasticizers and their primary metabolites on a L929 cell line Phthalic acid esters have been widely used to improve the plasticity of PVC medical devices. They carry a high exposure risk for both humans and the environment in clinical situations.
  • Are alternative plasticizers cytotoxic in vivo?
  • Objectives: Our study focuses on the in vitro cytotoxicity of two alternative plasticizers (DINCH and DINP) contained in certain medical devices. They are likely to migrate and be transformed in vivo into the primary and secondary metabolites by a metabolism similar to that of DEHP.
  • Is Deha cytotoxic?
  • DEHA showed no cytotoxicity, but its corresponding monoester ( MEHA) produced a cytotoxic effect at 0.05 mg/ml. In clinical situations, medical devices can release plasticizers, which can come into contact with patients. In vivo, the plasticizers are quickly transformed into primary metabolites.
  • Are plasticizers toxic?
  • All plasticizers induce an action on cell proliferation at 0.1 mg/ml. DEHP, ATBC and DINCH are considered as potentially toxic in the standard EN 10993-5. All plasticizers primaries metabolites cause a decrease in cell viability except MOTM. MINCH causes a very high inhibition of cell proliferation.
  • Are plasticizers toxic to fibroblasts?
  • Concerning cytotoxicity of plasticizers, no effect was observed at 0.01 mg/mL. DEHP and DINCH caused a decrease in L929 cell proliferation from the concentration of 0.05 mg/mL, and their effect was massive at the highest concentration, with total cell death. DINCH was as toxic as DEHP for the L929 fibroblast cells.
  • Are plasticizers cytotoxic?
  • However, authors report difficulties applying the EN 10993-5 ( NF, 2009) standard for plasticizers: these substances are hydrophobic, and cannot be used as they are for direct contact in a culture medium. It is therefore necessary to use a solvent for these materials, which is itself non-cytotoxic toward the cells, to perform the tests.
