What Oryza Sativa Starch does

Absorbs oil and sebum from the surface
Gives a soft, matte-like feel
Helps powders spread smoothly

Rice starch comes from the grains of rice. The starch is separated during processing, washed, and dried into a fine white powder. Starch is a natural carbohydrate that plants store as energy, and rice is one of the common sources used for it.

Formulators use rice starch because it absorbs oil and moisture well without feeling heavy. In dry shampoo, it is often used to soak up oil at the roots, which helps hair look fresher between washes. It also gives powder products a soft, silky slip. Its texture is light and dusty, so it blends easily into other ingredients.

Good for

Good for people who want a lightweight powder that soaks up oil, such as in dry shampoo or powder makeup.
