Kind Code:
A1
Abstract:
The present invention relates to inorganic powder and a method for preparing same, the inorganic powder being fatty-acid-coated inorganic powder for cosmetics and comprising a zinc-fatty acid soap coating layer on the surface thereof through dry coating. Specifically, by adding zinc oxide to inorganic powder, adding fatty acids thereto, and allowing a reaction to occur therebetween while heating to thereby coat the inorganic powder with a zinc-fatty acid soap, even if unreacted substances remain during preparation, the coated inorganic powder is safe for the skin since both zinc oxide and the fatty acids are substances that are widely used in cosmetics and ensure safety for the skin, and due to being aluminum-free, the coated inorganic powder can improve the negative image of causing Alzheimer's disease. In addition, since inorganic powder coated with a zinc-fatty acid soap is prepared by a dry method, water is not used, and thus, there are the advantages of preventing environmental pollution, saving energy, and shortening manufacturing time.
