ALUMINUM-FREE, FATTY-ACID-COATED INORGANIC POWDER AND METHOD FOR PREPARING SAME

Abstract

The present invention relates to a fatty acid-coated inorganic powders for cosmetics, comprising a zinc-fatty acid soap coating layer on the surface of the inorganic powders through dry coating, and a method of preparing the same. In particular, by adding zinc oxide to the inorganic powder, adding fatty acid thereto, and reacting the same by heating so that zinc-fatty acid soap is coated on the inorganic powder, even if unreacted substances remain during production, both zinc oxide and fatty acid are substances that are widely used in cosmetics and are safe for the skin, and since they do not use aluminum, they can improve the negative image of causing Alzheimer's disease, and further, since the inorganic powder coated with zinc-fatty acid soap is manufactured by a dry method, it is possible to prevent environmental pollution by not using water, and also to save energy and shorten the manufacturing time.
