INCI: Oryza Sativa Starch
Oryza Sativa Starch (rice starch) is a high-polymeric carbohydrate derived from the peeled seeds of the rice plant (Oryza sativa L., Poaceae). It functions primarily as an absorbent and mattifying agent, soaking up excess sebum and oil on the skin surface to create a smooth, shine-free finish. It also acts as a viscosity controller and bulking agent in powder-based and creamy formulations, and is widely used as a natural alternative to talc.

Is Rice Starch safe? Key considerations
Can Rice Starch cause irritation?
Low RiskRice starch is well tolerated by most skin types, including sensitive skin. The CIR Expert Panel (Cosmetic Ingredient Review) concluded it is safe in current practices of use. Rice-derived ingredients are generally considered non-allergenic; rare reactions have been linked to raw rice proteins, not cosmetic-grade processed starch. No EU Annex II or III restrictions apply.
Does Rice Starch increase sun sensitivity?
No RiskRice starch has no photosensitising properties. No increased sun sensitivity is expected from topical use, and no special SPF precautions are required based on its presence in a formulation.
Is Rice Starch safe during pregnancy?
SafeRice starch is considered safe for topical use during pregnancy and breastfeeding. Motherfigure classifies it as 'limited data suggests no known risk.' The CIR Expert Panel found no reproductive or developmental concerns. As a plant-derived starch with minimal dermal absorption, systemic exposure is negligible.

Individuals with known rice allergy (rare) should review the considerations above before use.
