b. a plurality of prills within the internal volume comprising:
i. from about 1% to about 60%, by weight of the prills, of a cationic surfactant chosen from behentrimonium methosulfate, brassicamidopropyl dimethylamine, behentrimonium chloride, stearamidopropyl dimethylamine, and/or behenamidopropyl dimethylamine;
ii. from about 10% to about 90%, by weight of the prills, of a fatty alcohol;
wherein the prills dissolve to form a gel network;
wherein the pouch comprises a melting point of greater than 45° C.; and
wherein the internal volume is adapted to contain about 0.5 to about 5 grams of the prills.
