A plasticizer for propellant compositions is 2-hydroxy-3-butoxypropyl oleate. The plasticizer can be incorporated into propellants which conventionally include a binder fuel component, oxidizer component, isocyanate curing agent as well as other conventional components as desired such as bonding agents, curing catalysts and ballistic modifiers. Specifically, a preferred propellant having the internal plasticizer therein includes ammonium perchlorate oxidizer, HTPB binder, aluminum powder fuel, isophorone diisocyanate curing agent, a bonding agent and a delayed quick-cure catalyst. The migration of the plasticizer is substantially reduced so as to extend the shelf-life of rocket motors having the plasticized propellant therein.
