Specialty Bleaching

Hydrogen peroxide is used to bleach a wide range of different products. The standard approach is the application of H₂O₂ under alkaline conditions. The concentration and the pH value can differ in a wide range in order to take care of the specific sensitivity of the products to be bleached. Wood veneer, wooden products, straw and grasses are examples for these products. Hair and bristle need specially buffered bleaching conditions to maintain the raw materials quality. Other products are bleached under weak to strong acidic conditions, e. g. sulfuric acid, vegetable oils or animal products like fish oil.
