Rhus Semialata Extract
What is Rhus Semialata Extract?
Rhus semialata Extract is obtained from the nutgalls of the Rhus semialata tree, a sumac species native to Asia, where insect activity induces gall formation packed with hydrolyzable tannins and phenolic compounds like gallic acid. Classified as a botanical extract in cosmetics, it serves mainly as a skin conditioning agent in formulations such as lotions, creams, and toners. The tannins provide astringent action by interacting with skin proteins to form a subtle film, which aids in preserving moisture, refining texture, and promoting a supple feel. This natural extract contributes to product stability and sensory qualities, drawing from traditional uses in Asian herbal practices adapted for modern skincare.
