Perstorp of Sweden (U.S. office in Toledo, Ohio) will launch at the K 2013 show this month a general-purpose, non-phthalate plasticizer called Pevalen. It's a polyolester plasticizer based on food-approved raw materials. Food-contact approval is currently under way. Pevalen boasts high efficiency and requires less plasticizer in most formulations. Low migration and volatility, along with excellent UV stability are claimed. It is also said to blend faster and easier with PVC than most other plasticizers, which reduces processing time.
