Zusammenfassung:PURPOSE:To obtain scillaneophan powder having excellent dispersibility and stability by compounding tall oil fatty acid to a scillaneophan powder prepara tion containing scillaneophan and a basic or neutral inorganic carrier. CONSTITUTION:The objective scillaneophan powder preparation can be produced by compounding tall oil fatty acid to a powdery agent containing scillaneophan {dimethyl(4-ethoxyphenyl) [3-(3-phenoxy-4-fluoro)phenylpropyl]silane} and a basic or neutral inorganic carrier (especially preferably calcium carbonate). Tall oil fatty acid is an unsaturated fatty acid especially composed mainly of oleic acid and linolic acid and has resemblance to soybean fatty acid. The amount of the tall oil fatty acid is preferably about 0.1-0.5wt.% based on the final powdery preparation. The active component of the powdery agent is effective for keeping the stability of scillaneophan and remarkably improving the dispersibility of the powdery agent.
