| abstract |
This disclosure relates to bleaching laundry compositions comprising a chlorine bleach, an optical brightener, preferably of the sulfonated triazole class, and a reducing agent such as inorganic sulfites, organic sulfinates, water-soluble phosphites, and inorganic alkaline materials combined with hydrogen peroxide. The presence of the reducing agent enables the composition to enhance brightening of the fabric being cleaned without adversely affecting the bleaching thereof to any appreciable extent. The optional addition of a detergent or surface active agent, also beneficially affects the brightener intensity. |
