Deep White 2B Powder is a high performance optical brightener which is especially formulated for the textile and paper industries for the reduction of the tint and yellow shades of the paper and the white fabrics. It improves the brightness of the materials on which it is applied by absorbing all the short wavelengths and invisible radiations. This powdered compound is a medium substantive brightening agent which makes it suitable for the cellulosic fibres and its blends.
