Widespread occurrence of phthalate and non-phthalate plasticizers
Besides phthalates, adipates, tributyl phosphate (TBP) and dibutyl sebacate (DBS), are used as plasticizers in synthetic polymers ( EU, 2008, LCSP, 2011 ). Adipates (especially, di (2-ethylhexyl)adipate; DEHA) and DBS are used in soft plastics, especially food wraps and films.
Dibutyl sebacate
Dibutyl sebacate (DBS) is an organic chemical, a dibutyl ester of sebacic acid. Its main use is as a plasticizer in production of plastics , namely cellulose acetate butyrate , cellulose acetate propionate , ethyl cellulose , polyvinyl butyral , polyvinyl chloride , polystyrene , and many synthetic rubbers (especially nitrile rubber and neoprene ) and other plastics.

Effect of plasticizer on the electric-field-induced adhesion
The plasticizers DOP and DBP connect PVC chains and allow only a limited rotation of PVC chain segments. Consequently, the number of free dipoles decreases . In contrast, for DEA and DBS plasticizers, the PVC chains are not restricted and the dipoles on the PVC chains are free to respond in the applied electric field.
Widespread occurrence of phthalate and non-phthalate plasticizers
DBS are used in soft plastics, especially food wraps and lms. The occurrence of adipate esters at concentrations of a few thousand mi- crograms per gram in plastic food packaging materials...
