Abstract
PURPOSE: To obtain a sufficient modifying effect without using an unfavorable organic solvent, by using a salt of a polyamino acid in the treatment for controlling surface activity of inorganic powder.
CONSTITUTION: When a perfume or drug coexists with inorganic powder such as kaolin, talc, etc., an acidic or basic the powder exhibit acidity or basicity, to produce an offensive odor and decomposition. To prevent this, the powder is dispersed into an aqueous solution of a salt of a polyamino acid, and, if necessary, heated, so that the powder is sufficiently absorbed on the salt of a polyamino acid and dried.
