PROBLEM TO BE SOLVED: To provide a precipitate preventing agent composition for an aqueous coating material, which is excellent in dispersibility, thixotropy, and precipitate preventing capability for pigment and the like, when preparing the aqueous coating material therewith. SOLUTION: The precipitate preventing agent composition includes a polyamide [A] obtained by reacting a 4-40C diamine with a 4-40C dicarboxylic acid and having a weight average molecular weight of 1,000-4,500, a polyolefin wax [B] having a weight average molecular weight of 1,000-3,000, and a surface active agent [C].
