Ground Joshua-tree yucca — a natural saponin-rich scrub/cleanser material. Gentle in rinse-off; saponins can sting eyes.
Yucca Brevifolia Powder is dried, milled material from Joshua tree (Yucca brevifolia), a Mojave-Desert arborescent yucca. Like other Yucca species, it is rich in steroidal saponins (yuccaosides, yuccagenin glycosides) used traditionally by indigenous peoples for washing hair and skin. In cosmetics it acts as a mild natural cleanser, foaming agent, and mechanical exfoliant/bulking particle. Saponins provide its surfactant-like action but also account for its main safety flag — eye and mucous-membrane irritation at elevated concentration. The plant is protected in many jurisdictions, so sustainable sourcing is a relevant consideration. Dedicated cosmetic safety data is limited, and supplier standardization varies.
