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
