About

Threitol is a cosmetic ingredient used in product formulations. Its specific function may vary between products. Exercise caution due to limited available safety data.

Threitol is a tetrahydroxy alcohol (C4H10O4) used as a humectant and skin conditioning agent in cosmetics. It is closely related to erythritol which has been evaluated for safety. The ingredient is not restricted in EU Annex II or III. It is a small, well-characterised molecule with low toxicity and is commonly present in foods and natural systems. JECFA has assigned an acceptable daily intake of 'not specified' for erythritol-like polyols, supporting a safety score in the 90s.
