Polyvinyl Acetate
Polyvinyl Acetate (PVAc), a synthetic resin prepared by the polymerization of vinyl acetate has good potential as an edible coating. It coatings had high gloss, even after immersion of coated surfaces in water. The primary advantages of using PVAc as an edible coating are its unique combination of properties and its low cost has been already used in pharmaceutical coatings and as an ingredient in chewing gum. (Approved by FDA 172.615)
PVAc mainly used in pharmaceutical coatings and as an ingredient in chewing gum.
