Denture Cleansers

Denture cleanser formulations containing at least 25% Oxone® provide excellent decolorization of food and other organic stains. In addition, formulations usually include sodium perborate monohydrate, sodium carbonate and/or bicarbonate, and may also include citric acid, EDTA or DTPA chelants, flavor/fragrance ingredients, and food colorants. Cleansers are often tabletted, but may be delivered in granulated form in sachets. The long shelf life of these products requires moisture barrier packaging materials, such as a heat-sealed wrap of flexible reverse-printed polyester laminated to foil, which is extrusion coated with a sealant layer of DuPont™ Surlyn® ionomer resin.
