Not reviewed
Sensitization risk Moderate

The Cosmetic Ingredient Review (CIR) has not yet assessed Methyl Propyl Diketone. While a closely related chemical, Methyl Propyl Ketone (2-Pentanone), is noted for being free of common irritants, a structurally similar alpha-diketone, 2,3-Pentanedione (Acetyl Propionyl), is classified as a moderate skin irritant and strong eye irritant, with a documented danger of skin sensitization. This information suggests a moderate sensitization risk for Methyl Propyl Diketone, necessitating cautious use.

Verdict

Questionable

Given its primary role as a fragrance ingredient, lack of CIR review, and potential for moderate irritancy and sensitization based on chemically similar compounds, Methyl Propyl Diketone is of questionable suitability for precision skincare formulations.
