The invention relates to perfume-containing bar compositions in which the effect of said perfume(s) (e.g., longevity) is enhanced relative to comparative bars in that perfume-containing bar of the invention, comprise less than about 35% soluble surfactant. The invention further comprises a process for enhancing deposition/longevity of perfume, for example, by controlling the level of soluble active relative to insoluble active and/or by increasing levels of perfume.
