To preserve the lotion an additional month, you can stir in Leucital liquid as a preservative at the very end of the lotion-making process. You will still want to keep the lotion refrigerated, but it will extend the shelf life to a total of 3 months instead of 2 months. Use 2% by weight of Leucital to the weight of the lotion. If your lotion weighs 50g, you’ll use 1g of Leucital.
