Disclosed is a cosmetic soap-gelled solid stick composition, which maintains its shape and aesthetic properties even when stored at high temperatures for long periods of time. The composition includes at least one alcohol (monohydric and/or polyhydric), water, and a soap gelling agent, the alcohol being a solvent for the soap gelling agent, the soap gelling agent being alkali metal (e.g., sodium) salts of fatty acids having C.sub.12 -C.sub.22 carbon chain length. At least 65% by weight, of the total weight of the soap gelling agent, are alkali metal salts of fatty acids having C.sub.20 -C.sub.22 carbon chain length.
