PURPOSE:To improve stability for long term storage of oleophilic fine powder by transforming the powder to liquid suspension by mixing the powder with molten wax and mixing the mixture further with an emulsifier. CONSTITUTION:Fluid A is prepd. by mixing oleophilic fine powder with molten wax. On one hand, an emulsifying liquid B is prepd. by dissolving a cationic surface active agent, a nonionic surface active agent, and hydrochloric acid in warm water. The fluid A is mixed with the emulsifying liquid B in an emulsifying machine to prepare a liquid suspension C. The product is cooled to ordinary temp. and then filtered by a filter to separate to a suspension of slurry D and wax emulsion E. An emulsifier F consisting of the cationic surface active agent, nonionic surface active agent and hydrychloric acid, is added to the suspension of slurry D, and the mixture is stirred to prepare the aimed emulsified liquid.
