THE CSE SILVER POLISH Combining the ingredients that produce the best sheen o n sterling silver is often a problem for the polish maker. In this case, the separation problem couldn't be solved satis factorily by homogenization or colloid miiiing — and a number of products tested could not prevent the separa tion without making the emulsion too thick for easy use. Then Carbopol 934, the new water soluble resin from B.F.Goodrich Chemical Company, was tried. Carbopol 934 — ideal for extremely high viscosity at . 5 % concen tration — is also a very efficient suspending or dispersing agent at lower concentrations. At . 3 % concentration or less it produces stable suspensions with relatively low viscosities — gives just the right consistency for easy application and removal. Best of all, the suspension is permanent — no more need for "shake well before using" on the jar. Carbopol may be the answer to your need for an improved product or application. Information and samples are avail able. Write Dept. DA-3, B. F. Goodrich Chemical Com pany, 3135 Euclid Avenue, Cleveland 15, Ohio. Cable address: Goodchemco. In Canada: Kitchener, Ontario.
