  • Patent number: 5773399
    Abstract: Granular laundry detergents are formulated with percarbonate bleach and oxidation-sensitive ingredients such as brighteners, enzymes, perfumes and the like. The storage stability of such compositions is improved by the presence of silicate. For example, the tendency of stilbene-type brighteners to form undesirable yellow shades in the presence of percarbonate is diminished by the corporation of silicate materials into the granules.
