We endeavour to only use the most skin and planet friendly ingredients in our products. Occasionally it is necessary to use a raw material that is preserved with very small amounts of a mild preservative such as potassium sorbate or phenoxyethanol to ensure that no bugs can grow. This does not mean that we add synthetic preservatives in the entire formula. Potassium sorbate is the potassium salt of sorbic acid which is found in nature, for example in certain berries. Although it is nature-identical, sorbic acid is not currently commercially available from a natural source.
