A unitary fibrous structure comprising one or more plies of a plurality of water-soluble fibrous elements and a plurality of discrete water-soluble, active agent-containing particles present between the plies of the plurality of water-soluble fibrous elements, wherein the plurality of discrete, water-soluble, active agent-containing particles exhibits a median particle size of from about 1 μm to about 1600 μm as measured according to the Median Particle Size Test Method and wherein at least one of the water-soluble fibrous elements comprises one or more fibrous element-forming materials;
wherein one or more active agents are present within at least one of the plurality of water-soluble fibrous elements at a level of greater than 20% by weight on a dry fibrous element basis or the unitary fibrous structure at a level of greater than 20% by weight on a dry fibrous structure basis; or both; and
wherein the water-soluble, active agent-containing particles comprise at least one of anionic surfactants, amphoteric surfactants, zwitterionic surfactants, or silicones.
