LOCKSON TRIPOLYPHOSPHATE offers the chemical industry an effective
combination of water softening, dispersing and sequestering properties plus a high compatibility with varied mixtures. The ability of its aqueous solutions to disperse viscous or gummy materials, and in general, to deflocculate, suspend and otherwise modify water insoluble substances . . . suggests experimental application to your own particular problem.

WATER SOFTENING Blockson S T P P saves soap by softening hard water so that the soap can not react with the calcium and magnesium.
conditions of use. I t retains its seques tration properties indefinitely at room temperatures.
THRESHOLD TREATMENT
HYGROSCOPICITY
Threshold additions of a few parts per million inhibit precipitation of the cal cium and magnesium hardness elements.
Its low hygroscopicity keeps Blockson S T P P free flowing under normal con ditions of use. I t can be conveniently stored or handled and accurately meas ured in its dry state.
DISPERSION Its dispersing properties help in forming a stable suspension of the dirt in laun dering operations . . . thus preventing its redeposition on the washed articles, even during the rinsing operation.
SEQUESTRATION The sequestered calcium and magnesium is held in a soluble combination—not affected by addition of substances that normally precipitate these hardness ele ments.
STABILITY Blockson S T P P is stable through a wide range of temperatures—even in hot alkaline solutions under normal
