  • Can glycerol trilevulinate plasticizer be a bio-based plasticizer?
  • Nonetheless, phthalates are still widely used for their versatility, high plasticization effect, low cost, and lack of valuable alternatives. This study presents the fully bio-based and versatile glycerol trilevulinate plasticizer (GT) that was obtained by the valorization of glycerol and levulinic acid.
  • How are plasticizers analyzed?
  • We measured plasticizers in 34 vegetable oils, 10 milks, 18 infant formulas, and 9 cheese powders from macaroni kits using gas chromatography coupled with mass spectrometry (GC-MS). We analyzed plastic packaging composition using FTIR spectroscopy.
  • How to design bio-based plasticizers?
  • In summary, before designing bio-based plasticizers, researchers should first start from the plasticization mechanism, considering the molecular weight, chain length, number of polar non-polar groups, and prior toxicity of the plasticizer molecule.
  • Which products have the highest and lowest plasticizer concentrations?
  • In this study, the products with the overall highest plasticizer concentrations (14,900 ng/g in a refined avocado oil with 12,000 ng/g from DEHT) and lowest plasticizer concentrations (a refined canola oil, 9 ng/g plasticizer entirely from DEHP) were both oils.
  • Are bio-based plasticizers safe?
  • The toxicological tests showed the median lethal dose of the plasticizers LD 50 > 5 g/kg, indicating the safety of the plasticizers. Some other bio-based plasticizers are also worthy of attention.
  • Are DBS and DHS a good plasticizer for PVC?
  • Where data was available, the results from this study are in good agreement with the experiment; we conclude that DBS and DHS are most promising green plasticizers for PVC, since they have properties comparable to DEHP but not the environmental and toxicity concerns.
