about 40 to 60% by weight of a reducing agent selected from the group consisting of thiourea, thiourea dioxide, and alkali metal sulfoxylate formaldehyde;

about 5 to 20% by weight of an anionic surfactant;

about 1 to 6% by weight of an anti-foaming agent;

about 5 to 15% by weight of a dye or soil redeposit prevention agent; and

about 20 to 40% by weight of fillers.

2. The composition of claim 1 wherein said fillers comprise buffers and stabilizers.

3. A process for desizing and decolorizing fabrics or garments in a washer which includes placing into said washer a composition according to claim 1 in water in a liquor ratio of about 10:

1 to 30;
