Oryza Sativa (Rice) Starch
Oryza Sativa (Rice) Starch
Rice starch is a plant-derived polysaccharide obtained from Oryza sativa. In cosmetics it functions primarily as an absorbent, mattifying, bulking, and texture-improving powder. It can reduce the feel of greasiness, improve slip, and help disperse oils or moisture in powders, creams, and dry shampoos. It is generally considered a low-risk, inert cosmetic support ingredient rather than an active treatment ingredient.

Risks & Warnings
Generally low risk. Potential issues are mainly physical: dustiness or airborne powder may irritate eyes, nose, or airways in sensitive individuals. Rarely, contaminated or poorly processed starches can contribute to irritation or microbiological concerns in formula if manufacturing quality is poor. Not a meaningful source of comedogenicity or photoreactivity.
