Miglyol:Miglyol is based on Glycerine. Glycerine is produced out of plant oil. In Europe this oil is usually produced from canola (=colza, lat.: Brassica napus), and the product we use is also based on canola grown in Europe.Sodium Carboxymethylcellulose:This ingredient derives from Cellulose. Cellulose is produced from trees or cotton wool. The supplier of the ingredient of Secure Adhesive is using Scandinavian fir and spruce exclusively for our ingredient as we insist on very high quality.Polyvinyl Acetate (PVA):This is a non soluble ingredient responsible for this main difference of secure to other competitors. PVA is completely inert, non allergic, does not affect the taste and can not be absorbed. Polyvinylacetate is a very common ingredient in chewing gums and is registered as substance for chewing gum base in Europe as well as in the USA, where it is approved as food ingredient by the FDA.
