Oryza Sativa (Rice) Hull Powder
What is Oryza Sativa (Rice) Hull Powder?
Oryza Sativa (Rice) Hull Powder is derived from the tough outer husks of rice grains, a common agricultural byproduct obtained during milling. Composed primarily of fibrous cellulose and silica, it forms a fine, irregular powder ideal for physical exfoliants. In cosmetics, it appears in facial and body scrubs, polishing masks, and gentle cleansers. The particles deliver mild mechanical friction against the skin surface, dislodging dead cells and impurities to enhance texture and product glide. Its natural origin makes it a biodegradable alternative to plastic microbeads, supporting sustainable formulations. Particle size variation allows customizable exfoliation intensity, while its inert nature ensures compatibility across product types without chemical reactivity.
