Abstract
A composite powder containing a powdery base and aluminum hydroxide adhered to at least a portion of the surface of the base, wherein said adhered aluminum hydroxide in the form of a spherical and net structure is comprised preferably in a large amount. In case of using in powdery cosmetics, this composite powder hides wrinkles, pore openings and hard texture of the skin, and thus maintains the correcting effect of the troubled morphology of the skin. Thus, it exerts excellent effects of imparting natural gloss and color tone to the makeup coating without darkness, being superior in a feeling of 'elasticity' and transparency, and the like, compared to the conventional products. The effect of the above object can be more enhanced by the surface treatment such as a further surface treatment by silicon on the surface of said composite powder.
