ABSTRACT:
A bleaching composition for cellulosic materials such as paper pulp, cotton and cotton blends. The chemical system of the present invention includes a mixture of sodium hydroxide, optical brighteners and an enhanced hydrogen peroxide including a silicate-free stabilizer. In the preferred embodiment, the silicate-free stabilizer includes; magnesium acetate; phosphonic acid derivative or substituted phosphonic acids; dipicolinic acid; and the balance water. The resulting textile goods are soft, absorbent, silicate-free with a Hunter Scale whiteness of greater than about 85. Because a silicate-free stabilizer is used, low levels of extractable solids are obtained.
