Lotion bars or bath fizzies don't have water, so you wouldn't need a preservative. Citric acid is a Ph adjustor for bath & body products, but it's needed for bath fizzes for the chemical reaction. Vit. E (an anti-oxidant) or grapefruit seed extract (could be adulterated with Trichlosan which is a preservative, but a harsh one) are not preservatives. Stearic acid is normally used in regular lotions and not needed in lotion bars. There aren't any natural preservatives on the market today for the home crafter that truly work for all mold, germs and bacteria. If you want to make lotion bars, start with 1/3 liquid oils, 1/3 butter(s), 1/3 wax.
