About UNCARIA GAMBIR EXTRACT
A catechu extract from Uncaria gambir used as an astringent in cosmetics; contains condensed tannins (proanthocyanidins) and can trigger allergic reactions in susceptible individuals.
Detailed Analysis
Uncaria gambir (Gambier catechu) is a vegetable tannin extract rich in (+)-catechin, epicatechin, and gambiriin A. Its astringent properties are exploited in skincare for oil control and pore-minimising effects. EU CosIng shows no Annex II or III restriction specifically for Uncaria gambir extract. However, catechin-rich extracts have been subject to IFRA monitoring for sensitisation. The score in the 60-74 range reflects moderate concern around tannin allergenicity in leave-on products.
