ALLANTOIN PABA
Commonly Found In
Overview
Allantoin PABA is a combination ingredient that links the skin-soothing allantoin molecule with PABA (para-aminobenzoic acid), a UV absorber. It is banned in EU and UK cosmetics due to the PABA component's potential to cause photoallergic reactions. Rarely encountered in modern formulations.
Also known as: allantoin p-aminobenzoate, allantoin para-aminobenzoic acid
Key Benefits
The allantoin component may help soothe and condition skin, while the PABA component provides UV absorption. However, clinical evidence indicates a meaningful photoallergic sensitization risk, leading to its ban in the EU and UK.
