Erythritol is highly compatible with most cosmetic ingredients and presents no known significant incompatibilities at typical use levels. It blends well with other polyols and humectants to provide synergistic moisture retention. It is stable across a wide pH range and does not interact adversely with common preservatives or actives.
Formulation notes
Erythritol is a four-carbon sugar alcohol derived by fermentation that functions as a humectant by attracting and retaining moisture in the skin. It is valued for its mild, non-sticky feel compared to glycerin and for its ability to improve skin hydration without tackiness. It has a good safety profile, is well tolerated by sensitive skin, and also demonstrates some antioxidant and cryoprotective properties in certain formulation contexts.
