Safety score · 0–100

Good

Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.

An ester derived from levulinic acid and butanol — works as a skin-conditioning agent with a pleasant, mild scent; low concern at typical cosmetic levels.

Butyl levulinate is the ester of levulinic acid (4-oxopentanoic acid) and n-butanol. It is used in cosmetics as a skin-conditioning agent and sometimes as a fragrance ingredient due to its mild, fruity odor. Levulinic acid derivatives are generally low in toxicity, and the esterification with butanol reduces any acid-related irritation potential. No regulatory restrictions are noted in EU CosIng or US FDA listings for cosmetic use.
