The Formula
Formulation
Stability
Malonic acid is prone to decomposition upon heating, releasing carbon oxide fumes and irritating smoke. Optimal stability in formulations is suggested within its pKa range of 2.83 to 5.69, consistent with the low pH requirements (around 3.5) for many bioavailable cosmetic acids.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) lists Malonic Acid as safe with restrictions. However, it is classified as acutely toxic if swallowed (Category 4) and capable of causing serious eye damage (Category 1). Furthermore, it is identified as a corrosive and irritant substance, necessitating careful handling and specific concentration limits for safe topical application.

Verdict
While offering exfoliation and skin brightening benefits, Malonic Acid's classification as a corrosive irritant with high irritancy potential and lack of detailed clinical efficacy data make its use questionable, requiring extreme caution and strict formulation controls.
