I’ve been wondering about whether you need to include a preservative when you use vegetable powders in formulas. From your Beetroot Lip Gloss, I take it you don’t. Am I right or is absence of a preservation just specific to this use of beetroot?
You must ALWAYS use a preservative when you have water/water soluble liquid and plant material in a product. The recipe for the beetroot lip gloss is a few years old and from the time Marie was still experiementing with preservatives (I’m guessing), because all of her recent lip gloss recipes that use glycerin include a preservative. If you were to make this recipe, I would deifinitely add a preservative.
