Safety
Safety Profile
While generally exhibiting low toxicity, the D-Threitol isomer is associated with GHS hazard statements indicating potential for skin irritation (H315) and serious eye irritation (H319). It has the capacity to cause skin inflammation in certain individuals and may worsen existing dermatitis conditions. Its safety for cosmetic use has not been reviewed by the Cosmetic Ingredient Review (CIR).

Verdict
Despite its humectant properties beneficial for dry skin, the 'medium' irritancy rating, potential to cause skin inflammation and exacerbate dermatitis, coupled with an unreviewed CIR safety status, positions Threitol as a questionable ingredient for precision skincare.
