Science
Mechanism of Action
This ingredient functions as a mild physical exfoliant, effectively lifting dead skin cells to refine skin texture and promote natural cellular renewal. Its high absorbency actively manages sebum and moisture, resulting in a desired matte finish. Beyond this, it offers antioxidant benefits, shielding the skin from environmental stressors, and aids in reinforcing the skin's protective barrier. Formulators also value its chelating, thickening, and stabilizing properties within formulations.

Oryza Sativa Hull Powder is stable under normal conditions, with an optimal pH range of 6.0-7.5 in a 1% solution. It is critical to avoid moisture exposure to maintain its integrity. When incorporated in the cold stage, it does not exhibit gelling; however, when heated, it can contribute to thickening and gel formation.

Safety Profile
Generally well-tolerated and recognized as safe for cosmetic applications by regulatory bodies such as the European Cosmetics Regulation and the CIR Expert Panel. Its natural origin contributes to its hypoallergenic profile, with adverse reactions being rare. However, Moumoujus emphasizes strict monitoring to ensure any potential contaminants, like pesticides or heavy metals, remain below established thresholds. A precautionary patch test is advised for individuals with exceptionally sensitive skin.
