SESQUKARBONATE OF SODA with α distinctive combination of physical and chemical properties not found in any other form
of alkali SOLVAY* SNOWFLAKE CRYSTALS brand of sesquicarbonate of soda has such an unusual combination of both physical and chemical properties that its uses range from that of an important ingredient in the manufac ture of luxury cosmetic products . . . to its application in a wide variety of basic industrial processes. The stable crystalline form of SOLVAY Sesquicarbonate of Soda gives it unusual physical properties. Sparklingly attractive, it remains free-flowing and noncaking even after prolonged periods of storage (in fact, it will frequently impart these qualities to dry materials with which it may be mixed). Almost entirely dustfree, it dissolves very rapidly and completely even at relatively low temperatures. Chemically, SOLVAY Snowflake Crystals is a true sodium sesquicarbonate, a double salt of sodium car bonate and sodium bicarbonate, corresponding to the formula N a 2 C O s · N a H C O s · 2 H 2 0 . The product thus retains many of the active chemical properties of the stronger alkali, along with the mildness of the lower pH component. SOLVAY Sesquicarbonate of Soda, in two grades o f bulk density—Snowflake Crystals and Snowline—is in expensively priced. Both densities are available in any quantity—from single packages to bulk carloads—to meet any requirements.
