22-Feb-17 A new independent study on the toxicological properties of Perstorp’s Pevalen™ non-phthalate plasticizer for PVC provides new evidence that Pevalen™ has no toxic properties and that it should be approved for food contact applications. Perstorp developed Pevalen™ (PETV or pentaerythritol tetravalerate) to provide uncompromising performance in close-to-consumer applications in flexible PVC. It is already widely used for products such as coated fabrics, but approval for use in products made from flexible PVC that may come into contact with food—conveyor belts in food preparation for example—is ongoing due to more strict testing requirements.
The recently completed test, carried out by the independent Research Toxicology Centre (RTC) in Pomezia, Italy, is a key requirement for approval by the U.S. Food and Drug Administration, the FDA. The tests showed that Pevalen™ is non-toxic, even at the highest dosage that is required by standard protocols. “This study is the latest and most detailed of several studies showing that Pevalen™ is non-toxic,” says Carina Fogelberg, Product Stewardship & Regulatory Affairs Specialist at Perstorp. “We are obviously very happy with the results, and we shall now move ahead to obtain full food contact approvals as soon as possible.”
