[Object] Provided are an aqueous dispersion composition in which hydrophobic powders are stably and uniformly dispersed in an aqueous phase, which has excellent handling workability, and which can exhibit sufficient water repellency, water resistance, sebum resistance, and the like when compounded in a cosmetic composition or the like; a use of the same (particularly, a material for a cosmetic composition); and a method of producing a cosmetic composition.
[Solving Means] An aqueous dispersion composition which contains at least (A) carboxylic acid-modified silicone in a liquid form at 50°C, (B) a hydrophobic powder, (C) a basic substance, and (D) water; and optionally (E) one or more alcohols selected from polyhydric alcohols and ethyl alcohols; wherein 80% by mass or more of a total composition is formed of the components (A) to (E), and the component (B) is contained in a range of 10% to 70% by mass of the total composition, and the component (A) is contained in a range of 5 to 30 parts by mass with respect to 100 parts by mass of the component (B); a material for a cosmetic composition using the same; or the like.
