Abstract: An accurately mixed fragrance can be provided. A fragrance generation device includes: a first ultrasonic vibrator provided in a water container that contains water and used for atomizing the water; a first emission hole used for emitting the water atomized by the first ultrasonic vibrator; a plurality of second ultrasonic vibrators provided in a plurality of perfume containers that individually contain multiple types of perfumes, respectively, and used for atomizing the perfumes; a plurality of second emission holes arranged around the first emission hole and used for emitting the perfumes atomized by the plurality of second ultrasonic vibrators; and a control unit configured to control driving of the first ultrasonic vibrator and the second ultrasonic vibrators.

Abstract: The present disclosure provides a powder-containing water-based composition having high powder dispersibility and stability even when the content by percentage of powder is high, and also having little stickiness. The powder-containing water-based composition includes (A) an aqueous phase constituting a continuous phase, (B) 10 to 45% by mass of a powder, and (C) 0.7% by mass or greater of a thickener. The thickener is a polymer that includes, as a constituent component, 2-acrylamido-2-methylsulfonic acid or a salt thereof. A content of an oily component is 15% by mass or less relative to the mass of the composition.
