Undaria Pinnatifida Powder

What is Undaria Pinnatifida Powder?

Undaria Pinnatifida Powder derives from Undaria pinnatifida, a brown macroalga commonly known as wakame seaweed, native to coastal regions of Asia and found worldwide. This edible seaweed is harvested, dried, and ground into a fine powder for cosmetic applications, particularly in powder-based formulations like face powders, dry shampoos, and masks. Botanically, it belongs to the Phaeophyceae class, rich in polysaccharides and minerals. In products, it functions by absorbing excess water and sebum to mattify skin and reduce greasiness, binding particles together for better cohesion in pressed formats, and adjusting viscosity to enhance texture, stability, and spreadability across emulsions and suspensions.
