Zusammenfassung:Described herein, a composition comprises an anionic surfactant system comprising from 1% to 30% of an anionic surfactant by total weight of the composition, wherein the anionic surfactant is sodium laureth(n) sulfate SLEnS, wherein n is the average moles of ethoxylation, wherein n ranges from 0 to 8, preferably from 1 to 3. The composition comprises from 0.01% to 2% of a cationic guar polymer by total weight of the composition, wherein the cationic guar polymer has a charge density from 0.6 meq/g to 2.5 meq/g. One or more coacervates are formed with the anionic surfactant system, preferably with the anionic surfactant, and the cationic guar polymer. The composition comprises from 0.001% to 10% of a plurality of polyurethane microcapsules by weight of the composition, wherein the polyurethane microcapsules comprise a shell material encapsulating a core material, said core material being disposed within said shell material, wherein said shell material comprises a polyurethane polymer and said core material comprises a benefit agent, wherein the polyurethane polymer of the shell material is the reaction product of the polymerization between one or more polyisocyanates and glycerine, and wherein the one or more polyisocyanates have at least two functional isocyanate groups. The one or more coacervates comprise one or more clusters. The one or more clusters includes a portion of the plurality of polyurethane microcapsules.
