About KIGELIA AFRICANA FRUIT EXTRACT
Extract from the African 'sausage tree' fruit — a traditional remedy now popular in anti-aging skincare for its firming, brightening, and anti-inflammatory effects. Generally safe topically, but raw fruit is toxic.
Detailed Analysis
Kigelia Africana Fruit Extract (CAS 223749-33-5) is derived from the fruit of Kigelia africana (Bignoniaceae), the African sausage tree. Rich in flavonoids, saponins, naphthoquinones, iridoids, caffeic acid, and phytosterols. In vitro studies show low cytotoxicity on healthy cell lines. Functions as a skin conditioning agent with demonstrated firming, anti-inflammatory, antimicrobial, and skin-brightening properties. Caffeic and ferulic acid inhibit tyrosinase for brightening. EWG rates it LOW concern across all categories. Note: raw fruit is toxic — the processed extract is considered safe for topical cosmetic use.
