  • Are plasticizers esters?
  • Plasticizers are almost invariably esters because of their specific requirements for interacting with the polymer. Plasticizers in flexible PVC must be closely associated with the amorphous part of the polymer at room temperature, and plasticizers must be fairly permanent.
  • Is the plasticizer fully acetylated monoglyceride based on hydrogenated castor oil safe?
  • The plasticizer fully acetylated monoglyceride based on hydrogenated castor oil (SNS) has been approved by European Union for food contact use without any restrictions. The plasticizer has no specific migration limit .
  • Does plasticizer have a migration limit?
  • The plasticizer has no specific migration limit . Migration studies of this plasticizer to acidic, alcoholic and fatty (sunflower oil) simulants have shown lower migration values than those observed for DEHP and DINP plasticizers, with a range of migration reductions from 50 to 100 times in aqueous simulants .
  • Do plasticizers cause genetic changes in humans?
  • Some studies developed in the 90's showed that some plasticizers of the phthalate family caused genetic changes in mice, but that was not observed in humans. Anyway, the concept of precaution was placed on low-molar mass phthalates, such as BBP, DIBP, DIHP and DEHP, limiting their use in some products.
