Atsko N-O-Dor II Powder is a combination of adsorbers, including Abscents crystals which soak up every trace of odor into permanent storage, while increasing pH to slow the creation of new odor. The powder performs wet or dry and washes away easily. N-O-DOR II Powder is a blend of 25% Abscent crystals in sodium bicarbonate (baking soda). Abscents crystals are a molecular sieve of alumino silicate molecules. The crystal framework of aluminium and silicon atoms forms a three dimensional network of internal cavities having a honeycomb-like structure. The crystals have a tremendous surface area. One teaspoon has an internal surface area equal to that of a football field. This huge surface are is available for the absorption of odor causing molecules. What sets Abscent crystals apart from others is that they are hydrophobic (water hating). This means they maintain their odor absorbing qualities in high humidity or even when soaked in water. Great for deodorizing footwear. Keep clothes in a plastic bag with N-O-DOR II Powder to quickly remove any odors.
