Vitamin C Coated

Introduction: This is a Vitamin C crystal coated with a thin film of medicineclass high polymer. The film is either aqueous high polymer or lipolytic high polymer .Observed under intensified microscope , most of the Vitamin C crystals are coated. Because of the film protection , the anti-oxidation ability of the product is stronger than those without films and has a better performance for moisture resistance. Coated VC and Coated VC-S both have two contents 90% and 95%.

Package: Net weight 25kg cardboard cartons/ drums ( or as per customer's requirements )
