Abstract

PURPOSE: To prepare the titled substance having high dispersibility and suitable for the control of the color of cosmetics, by adding an aqueous solution of a water-soluble ferrous salt dropwise to an aqueous solution of an alkali hydroxide or alkali carbonate, blowing air through the mixture, separating the produced precipitate from the solution by filtration, and leaving the precipitate to stand in a hydrogen atmosphere within a specific temperature range for a specific period.
CONSTITUTION: An aqueous solution of a water-soluble ferrous salt having a ferrous ion concentration of 20W150g/l, e.g. an aqueous solution of ferrous sulfate, is added dropwise to an aqueous solution of an alkali hydroxide or alkali carbonate having a concentration of 2W8mol, e.g. an aqueous solution of sodium hydroxide or sodium carbonate, and at the same time, air is introduced into the mixture. The produced precipitate is filtered, and left to stand in a hydrogen atmosphere at 250W350°C for 0.5W3hr to obtain ultra-fine powder of black ferrosoferric oxide having a particle diameter of ≤100mm and a specific surface area of ≥40m2/g.
