Federal Package offers both stock and custom lip balm formulas manufactured with hot pour, anhydrous filling processes. Hot pour formulations can reportedly have a longer shelf life because the blending process doesn’t include water and oil phases, which can separate over time. They also are less prone to bacteria growth since they typically don’t have water, so there is little for the microorganisms to feed off. Furthermore, waxes help products maintain their function and quality, acting as an emulsifier for other ingredients. They prevent oils from separating within the product and keep other ingredient substances together, per Federal Package. This purportedly makes a more homogenous finished product.Federal Package
