About

2-methyl-3-buten-2-ol is a cosmetic ingredient used in product formulations. Exercise caution due to limited available safety data.

This simple tertiary allylic alcohol exhibits relatively low toxicity compared to more complex unsaturated fragrance materials. The allylic system introduces mild sensitization potential, but the simple structure allows for more predictable metabolic degradation. IFRA assessment supports use at conventional fragrance concentrations, and EU cosmetic regulation does not place this substance on restricted lists beyond standard allergen disclosure requirements.
