Abstract

An absorbent substrate such as a wool dryer ball is imbued with a fragrance or treatment composition. The fragrance or treatment composition comprises an aqueous carrier, free fragrance, and encapsulated fragrance. The composition includes about 0.1 wt. % to about 5 wt. % free fragrance and about 0.1 wt. % to about 10 wt. % encapsulated fragrance. A kit includes absorbent balls, the fragrance or treatment composition, and an applicator for applying the fragrance or treatment composition onto or within the absorbent balls.
