Alkaline solid block composition

A solid block alkaline detergent composition containing an effective amount of a condensed phosphate sequestering agent, the stabilized composition comprising:

• (a) about 10 to 60 wt-% of an inorganic source of alkalinity;
• (b) about 10 to 45 wt-% of a condensed phosphate sequestering agent;
• and
• (c) about 1 to 15 wt-% of an effective stabilizing and reversion inhibiting amount of a reversion inhibitor, the inhibitor comprising a C.sub.4 to C.sub.6 monosaccharide, or a disaccharide comprising sucrose, maltose, lactose or mixtures thereof;
• wherein the solid block is packaged within a container and wherein less than about 15 wt-% of the condensed phosphate sequestering agent is reverted.

A solid stabilized block alkaline functional material composition containing an effective amount of a functional agent selected from the group consisting of an enzyme, a nonionic surfactant, a chlorine source, the stabilized composition comprising:

• (a) about 10 to 60 wt-% of an inorganic source of alkalinity;
• (b) about 0.1 to 60 wt-% of a functional agent;
• and
• (c) about 1 to 15 wt-% of an effective functional stabilizing and reversion inhibiting amount of a reversion inhibitor, the inhibitor comprising a C.sub.4 to C.sub.6 monosaccharide, or a disaccharide comprising sucrose, maltose, lactose or mixtures thereof;
• wherein the solid block functional material composition is packaged within a container.
