Melt together the oil and beeswax in a small saucepan over low heat or in a double boiler until melted. Remove from heat and add honey and blend mixture with a small whisk. Stir until cooled, and then add the essential oil. The essential oil helps preserve it; also, jojoba oil will help it stay good, since it does not turn rancid. You can mix the oils, too (ex. mix half jojoba/half shea butter...).
